A DC converter is needed to adjust the voltage generated by the PV cell so that it can be connected to the battery. DC converter devices have various efficiencies depending on the type of topology, as well as the selection of electronic components that make up the DC converter which has an impact on a lot of wasted energy in the electrical conversion process. According to Chapman (2005:105), the Buck Converter topology has an efficiency of up to 85%. A common challenge found in all types of DC converters is how to design a DC converter with high work efficiency. The author designed a Buck Converter with an efficiency of up to 90%, which can be integrated with a 20Wp PV Cell as input and a 12V50Ah VRLA Battery as output. The design begins by making a circuit simulation on the NI Multisim 14.2 software. Based on the simulation, a Buck Converter prototype was made with an Arduino Nano controller. Input Voltage Variation Test resulted that the maximum efficiency of the Buck Converter Simulation is 98% and the maximum efficiency of the Buck Converter Prototype is 92%. Duty Cycle Variation Test resulted that the maximum efficiency of Buck Converter Simulation is 99.3% and the maximum efficiency of Buck Converter Prototype is 96.4%. Load Variation Test resulted that the maximum efficiency of Buck Converter Simulation is 97.3% and the maximum efficiency of Buck Converter Prototype is 91.8%.

Miftahul Fikri, Christiono Christiono, Iwa Garniwa Mulyana K — Sun, 08 Jan 2023 06:24:39 +0000

Insulation failure due to high voltage phenomena such as corona discharge (CD) still occurs in many electrical systems in Indonesia. This is due to not being able to do early detection of CD. One form of CD is sound. As the first step for early detection of insulation failure in the form of clustering, a study is needed (in a 20 kV cubicle) that can optimize the sound characteristics of CD, which is the aim of this research. Based on observations on the needle-rod electrode 3 cm apart, the smallest breakdown was obtained at 34.3 kV. So that the classification of CD sound is set into 3 clusters starting from the cubicle voltage of 20 kV until before the breakdown occurs, namely 33 kV. The temperature in the cubical is between 27.5℃ - 35.3℃ and humidity ranges from 70% - 95%. Feature extraction was carried out using the linear predictive coding (LPC) method, then optimization of the likelihood function was carried out using the normal hidden Markov model which is expected to be used as a first step for early detection of insulation failure.

Kontrol Torka Pengereman Regeneratif Pada Sepeda Listrik Dengan Integrasi Ultrakapasitor

Sat, 04 Feb 2023 02:02:00 +0000

Regenerative braking on conventional electric vehicles utilizes the battery as a load in the braking phase to create reverse electric torque which will slow down the vehicle. This method has the disadvantage that the amount of braking torque depends on the maximum charging current of the battery. This final project examines a regenerative braking system using an ultracapacitor as a reverse electric torque-producing load that creates a slowdown in the rotation of the driving motor (BLDC/Brushless DC). The regenerative braking trial using ultracapacitors was carried out on a laboratory scale test model by varying the rotational load or inertia and the number of parallelized capacitors, which will see the effect on the amount of regeneration energy and braking torque that occurs. The load variations are 2.5 kg, 3.75 kg and 5 kg, speed variations of 600 rpm, 700 rpm and 800 rpm and variations of single, parallel ultracapacitor configuration. From the test results obtained the highest current, voltage and braking values at a load variation of 2.5 kg with a speed of 800 rpm and one ultracapacitor with a successive value of 1.57 m/s2, 5.8 mA and 7.87 V. As for the highest energy of 0.2091662 Joule obtained from a load variation of 5 kg with a speed of 800 rpm and parallel ultracapacitor. In addition, it is also known that the highest deceleration torque, on average, was obtained in the test with the lowest load mass, namely 2.5 kg. From the overall test results, it can be observed and concluded that the retarding torque is influenced by the maximum regeneration current that can be achieved, where the value is influenced by the type of capacitor and the regeneration voltage. So that the effective deceleration is only seen at low load inertia and less significant at high load inertia.

Thu, 09 Mar 2023 17:45:17 +0000

In 2018, RW 04 which is in the administrative area of Palmerah District, West Jakarta, has been designated as one of the slum RWs based on DKI Jakarta Governor Regulation number 90. This determination is based on aspects of physical environmental arrangement, social and cultural empowerment, as well as community economic empowerment . The waste problem is one of the indicators in the aspect of physical environmental management because 22% of domestic household waste in residential areas is transported to the TPA (Water Treatment Plant) less than 2 times a week. Improper waste management can have a negative impact on health, the environment, as well as on the socio-economic and cultural life of the community. Waste production at TPA per day averages 0.28 m³/day or around 0.1 tons/day, plastic waste reaches an average of 22.6%, which can be recycled around 17%. So plastic waste that can be recycled is 3.1 tons/day, this is a very potential business opportunity. The community must be given incentives in sorting organic and inorganic waste because if it does not provide added value to the community it will be difficult to invite the community to participate in managing waste, training, introduction and increasing the ability to manage plastic waste chopping machines so that people are interested in sorting the waste.

To help the community improve their economy and see the abundant water potential and apply science and technology in Gadog village, the team will build a catfish farming pond. What needs to be considered for catfish cultivation is the timing of feeding on time, while people spend all day farming in the fields / in the fields because of the far position. To facilitate this, feeding will use an automatic fish feeder that is equipped with photovoltaic at the top of the tool. While the application of science and technology uses a solar energy-based DC water pump, where this water pump will be used for the pond irrigation process. For fish feeders in feeding can be set according to needs, where in this case the time setting is made every 5 hours. The pond used is a conventional pond with a length x width x height of 3m x 2m x1m, with a total of 4 pool units which are divided into 1 pond for nursery, 1 pond for growth and 2 other ponds for harvest ponds. And for the water pump that is used to drain and or refill water to the pool, a DC water pump is used with a pump output capacity of 180 Watts, 12 Volts. Harvesting of fish is done after the fish are 3 months old from breeding at the age of 15 days.

Indonesia has two seasons, namely the dry season and the rainy season. When the rainy season comes, many areas will experience flooding, which can be caused by silting of rivers or heavy rainfall. To reduce the impact caused by flooding, the aim of PKM is to create an early warning tool for flooding. This tool can remind residents around the river to get ready to evacuate if the river water discharge has entered a residential area. From this technology, many people can apply it, for example, a tool that is implemented as a flood early warning using a solar cell power supply.

In this case the PKM Team will also implement a flood early warning tool with a microcontroller-based method using a PLTS power supply in the area around the river at Villa Mutiara Serpong housing, where when the rainy season comes the water discharge around the housing increases and can become a flood hazard. This tool uses the power supply from the PLTS as well as lighting, due to the condition of installing the early warning device a bit far from the PLN power pole, and it is unethical to take PLN electricity for equipment purposes.

The results of the PKM team of electrical engineering lecturers so that people can get to know more about the technology of flood warning devices and PLTS, how to install and maintain them, so they can understand if there is damage or subsequent problems.

Pengenalan Energi Baru Terbarukan Dalam Rangka Pemerataan Kelistrikan Di Desa Kadubeureum Kabupaten Serang Banten

Thu, 09 Mar 2023 17:52:05 +0000

Solar power plants (PLTS) convert electromagnetic energy from sunlight into electrical energy. This renewable energy-based power plant is one of the recommended solutions for electricity in remote rural areas where sunlight is abundant and fuel is hard to come by and relatively expensive. The Ministry of Energy and Mineral Resources has issued Ministerial Regulation (Permen) Number 49 of 2018 on the use of Rooftop Solar Power Plant (PLTS) systems by consumers of the State Electricity Company (PLN). The hope is that with this rule the business and solar panel industry can grow. The government first implemented a dispersed PLTS system for rural electricity in 1987, and expertise on photovoltaic systems is still in its early stages. This is due to the lack of availability of experts, skilled technicians, and engineering companies competent to design, build, and maintain systems. Meanwhile, a better supply chain of PLTS system parts is needed to ensure the sustainability of this system in Indonesia, especially in rural areas. For that we strongly support programs for new and renewable energy for remote areas that are difficult to get electricity supply. In an effort to support the use of new renewable energy we conduct community service with the theme "Education and Implementation of Renewable Energy in the Community in Kaduberuem Serang Village".

Provision of sufficient water for chili plants is very important because chili plants are plants that are very sensitive to water, if excess water will cause root rot, and vice versa if chili plants lack water, chili plants will die of drought. So that appropriate and precise technology is needed to meet their needs. Conventional irrigation systems have not been able to provide good water needs, so smart technology is needed to meet these needs. Wireless Sensor Network (WSN) technology is a good infrastructure for use in drip-based smart irrigation systems for irrigation systems, especially in open land irrigation. This technology is able to provide integrated information on land by dividing by cluster. So that information on the condition of the land can be obtained properly. This technology consists of a collection of sensors that are integrated with each other by using wireless as a link for each sensor node. To manage water distribution precisely and precisely, this technology uses the Long Short-Term Memory (LSTM) algorithm for its computing system. This algorithm will determine the distribution time of water in chili plants according to the data obtained from the sensor. This algorithm works on a centralized microcontroller module and is integrated with Solenoid valves and wireless sensor networks. The results obtained after testing this computational model are able to help monitor the need for irrigation water in chili plants with an accuracy rate of up to 96%, this condition is quite good compared to using conventional irrigation technology and drip irrigation technology without WSN.

When distributing electrical power from the substation to the load center, distribution channels are needed. According to Manokwari area data from the Customer Service Implementation Unit (UP3), interruptions can occur up to 70 times in one month in 2019 and require quite long handling times; however, disruptions are not reported directly. PLN (Persero) Company UP3 Manokwari has six feeders consisting of 13 to 40 distribution transformers. If there is interference, the field staff (Yantek) must follow each feeder route to find the location of the disturbance point. It takes a lot of time and effort. The long-term objective of this research is to detect the location of points and types of disturbances for each distribution network obtained from reports of raw data from the SCADA system for up to eight variables in applications planted on mobile devices based on spatial data, not only for small-scale distribution networks like Manokwari but also for large distribution networks. The study's objectives were to determine the location and sub-location of the disturbance point of each feeder in the distribution network using secondary notification data from the SCADA system displayed in the UP3 Dispatcher for mobile device applications. The algorithm C4.5 is used to obtain a classification pattern of point locations and disturbance types. Dijkstra's algorithm is used to determine the closest route based on spatial data from mobile devices. The research results are very helpful for Yantek officials to find the closest route to the disturbance location with 98.33% accuracy and report disturbances in the distribution network in real time.

Analisis Multivariat untuk Penentuan Pola Kebutuhan Beban Listrik secara Spasial Menggunakan Metode Geographically Weighted Regression

Dwi Anggaini, Adri Senen, Tri Wahyu Oktaviana Putri — Thu, 09 Mar 2023 18:45:36 +0000

Distribution system planning must be in accordance with the pattern of needs and load characteristics, so that the location and capacity of distribution substations can be determined. In general, the existing electrical load demand pattern approach is in macro and does not involve interactions between variables (multivariate), making it difficult to map and determine the existence of load centers. Therefore, a spatial approach to the pattern of Electric Load needs using the Geographically Weighted Regression (GWR) is a suitable method to overcome this. GWR is a linear regression method where the basic principle difference between GWR and ordinary linear regression lies in the weight of the location, so that each model will have a spatial effect. The linear regression model can be used to see the relationship between load density in each subdistrict and the most influential factor. This study uses the value of Variance Inflation Factors (VIF) as a criterion to determine the presence of multicollinearity between independent variables. The optimum weighting carried out in the GWR modelling is Adaptive Exponential with the Exponential kernel function because it has the smallest AIC value and the largest R Square that is 0.9853. The GWR analysis shows that the variables Housing, GDP, and Housing have a significant effect on Load Density in each village. While social factors do not have a significant effect on Load Density.

Recently, the use of cement for construction has shifted from Ordinary Portland Cement (OPC) to Portland Composite Cement (PCC). PCC cement is cement in the Indonesian Green Listing from the Green Building Council Indonesia, this is based on the industry’s commitment to environmental issues. PCC-type cement is easier to obtain on the market and has been widely used in construction in various environments, although its advantages have not been studied much. The use of PCC Cement is often feared for its strength as structural concrete when compared to OPC cement by service users. Therefore it is necessary to do research on the use of PCC cement. Flay ash is a waste of coal combustion which continues to increase rapidly every year. It is necessary to study the characteristics and utilization of fly ash waste to determine the potential of the fly ash. This study analyzes the performance of concrete using PCC cement by utilizing PLTU Indramayu’s fly ash as a cement substitution. The research method was carried out experimentally in the laboratory. In the early stages, material testing was carried out and then continued with the manufacture of test objects with variations in the use of fly ash as a cement substitution of 0%, 10%, 20%, 30% and 40% which were tested under pressure at the age of 7 days, 14 days and 28 days. The results of compressive strength at 28 days were 25.19 Mpa; 25.36 Mpa; 25.62 Mpa; 26.92 Mpa and 22.92 Mpa. The optimum compressive strength is found in variations of 30% fly ash as a cement substitution. PCC cement can be used in the manufacture of both structural and non-structural concrete, on the other hand the development of this type of PCC cement will help reduce emissions or environmental problems from industrial activities.

Electric vehicle technology is currently experiencing rapid development. Electric vehicles use energy sources derived from batteries. This is an advantage in electric vehicles because they do not produce exhaust gases. In thestamp duty, it is necessary to charge electric chargewhich will be used as an energy source in electric vehicles. Precise controls and monitors are needed to ensure the efficiency of battery use in Electric Vehicles. Efficiency is very important in Electric Vehicles. The battery monitoring system used by Electric Vehicles generally only shows how much electrical energy is left in Electric Vehicles. The battery charging process requires monitoring to determine the condition of the cell battery, Battery Management System (BMS), and energy management during the charging process. All monitoring results are displayed in a GUI (Ghrapical User Interface) that is adequate so as to help the user during the charging process. This controller can receive data read by the sensor and transmit the data to the created GUI. In addition, in the charging process, energy management needs to be carried out so that the charging process can be carried out optimally. Energy management is carried out by making arrangements in the BMS section. The results of the analysis on the monitoring system show that BMS settings can speed up charging time. The time required for the charging process without BMS setting is 6536s, after setting it only requires charging time of 3860s. BMS settings are carried out by paying attention to the constant current and constant voltage methods.

Shading is one of the conditions that gives impact to the performance of a solar panel. Shading can be caused by some reasons e.g. weather conditions (sunny day) or any object(s) exists around the solar panels (trees, humans, or other objects) that covers the solar panel to get the maximum amount of irradiation from the sun. If there is only a slight amount of shadow covering the surface of the module caused from a tree branch and other shadow sources, the solar panels will experience a significant decline of its power output this occurs because solar panels consists of a solar cells which connected in series[1][2]. In different condition when more areas of the solar panels shading from direct sun then the power output of the solar panels will become smaller and smaller[3-5]. In this study, testing will be carried out on the power output of polycrystalline and monocrystalline 300 Wp solar panels with 4 test scenarios, namely normal conditions, shadows due to buildings (25% irradiance reduction), shadows due to weather (90% irradiance reduction) and shadows due to trees (50% irradiance reduction). And from the research that has been done, there is a decrease in power output in both types of solar panels, which is an average of 35% of normal conditions.

A direct strike on the phase wire can cause a traveling wave which will also cause damage to the insulator, these events are called Sheilding Failures. These disturbances due to lightning will be more common in tropical areas which have high intensity of lightning strikes. Improvement of the protection system can minimize the damage caused by this direct strike. To protect overhead transmission line, planning for the construction of transmission towers must be equipped with reliable protection and isolation equipment. However, the reliability of protection and isolation systems often exceeds the standard provisions regarding overvoltage and isolation coordination. In areas with a high density of lightning strikes, there is a discrepancy between the design and the concept of isolation, which can be seen from the excessive number of insulators on the transmission tower, the choice of class of lightning arrester is too high, the distance between the equipment and the distance between the lightning arrester equipment is too far. This is what causes the transmission system that has been built not in accordance with the isolation coordination concept, so it needs to be re-evaluated in order to get a reliable and efficient protection system, and recommend improvements to the lightning protection and grounding system in the transmission line.

There are certain specifications that must be used in selecting batteries in solar power plants, such as how long a solar panel battery will last, and how much power the battery provides. In this study, there will be several criteria that will be used in comparing regarding battery energy storage options and several types of solar power plant batteries. When considering for solar energy storage options many specifications whose products are still very difficult the most important thing to use for this evaluation are battery capacity, power value, energy release (DoD). Capacity is the total amount of electricity that a solar battery can store measured in kilowatts – Hours (kWh). A battery with a high capacity with a low power rating will produce a fairly low amount of electricity as well as it can only be used to power some important electrical appliances while a battery with a low capacity and high power rating can run all household appliances but in a short time only a few hours. For this reason, this study obtained the results of the magnitude of DoD referring to the amount of battery capacity used with a battery capacity of 10 kWh having a DoD of 90% then it should not use more than 9 kWh of battery before recharging. In general, having a higher DoD will be able to take advantage of the battery capacity used.

Concrete beam is one form of embodiment of concrete material. The beam basically bears a bending moment followed by a shear force so that the stress that arises in each part or element shows characteristics that can be identified both based on deformation and damage patterns visually. Under certain conditions experimental concrete testing cannot be carried out with various limited resources. The finite element method (FEM) approach is quite reliable in analyzing the behavior of structural elements made of concrete both in elastic and inelastic conditions. However, for concrete inelastic conditions, further parameters are needed, namely the concrete damage plasticity parameter. Compressive and tensile behavior and their parameters are key in conducting FEM analysis to obtain stress output, deformation and failure mode of the element being analyzed.

In accordance with the Regulation of the President of the Republic of Indonesia No. 55 of 2019 concerning Battery-Based Electric Motor Vehicles has led to the growth of the motorized vehicle industry and products. As an innovation that is still new, of course it still needs various kinds of studies so that this product can truly be accepted by consumers, so producers must create products that depart from the voice of customers which in the end become reliable products that lead to industrial profits. In the research entitled, "Development of Product Design for Electric Motorcycles Using the Kano Model Integration Method in Quality Function Deployment (QFD)", this examines the use of integrating the Kano Model into Quality Function Deployment (QFD) with the House of Quality (HOQ) matrix, we can find almost all attributes have a negative gap value (except the vehicle body and display on the odometer) this indicates that the existing attributes of electric motorcycles have not satisfied consumers. while the results of attribute classification using the Kano method, obtained 25 attributes that fall into the important category. Among other things, 8 attributes are in the Must-be category, 5 are in the One-dimensional category, 7 are in the Attractive category, and 5 are Indifferent. The independent category can be omitted because this category has no effect on the satisfaction level of motorbike owners. From the results of the integration of the Kano method and Quality Function Deployment up to stage 3 (quality process) the output of the House of Quality stage 3 is obtained by taking into account the value of Ranking Priority Technical Contributions (%). Improvement efforts are obtained that need to be prioritized by electric motorbike manufacturers in increasing consumer satisfaction, with the 5 highest Quality Process contributions being full (battery) in 60 minutes (charging process speed) with a contribution value of 18.1%, improving battery quality (storage) with a contribution value of 17.0%, collaboration with associations (increasing charging stations) with a contribution value of 14.0%, (increased cooperation with) Swap Battery Company with a contribution value of 11.6%, and the use of aluminum alloy material (as a frame material) with a contribution value of 5.6%. But in general it can be concluded that the most important thing in the development of electric motorbikes is in terms of improving the quality (durability and charging power) of the battery.
