Optimasi Likelihood Function Suara Corona Discharge Menggunakan Model Normal Hidden Markov Sebagai Langkah Awal Deteksi Dini Kegagalan Isolasi

Miftahul Fikri — 2023-01-08

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

Rizki Pratama Putra — 2023-02-04

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.

Arief Suardi Nur Chairat — 2023-03-09

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.

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

Alex Fernandes — 2023-03-09

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".

This high school which was founded in 1965 accommodates around 1485 students (36 study groups), 68 teachers who teach 75 subjects, 27 classrooms, and other facilities. The activities of the Teaching and Learning Group were also assisted by 23 school administrators. Based on the results of initial interviews with the principal and several teaching staff, the management of the potential of the school, especially in the form of providing information digitally, cannot be categorized as good, because: 1) the management system is simple, and still uses conventional and manual methods, especially for information of school activities and public facilities; and 2) The form of promotion and registration for entering high school still uses manual methods so that it affects administrative and financial management. These things cause the development of the school is disrupted and in the end, become undeveloped. The potential for school development can be seen from several perspectives/aspects, which include: 1) Development of promotion patterns to attract interest, not only students, but also investors; 2) Development and use of websites as a means of disseminating school information; and 3) expansion of coordination and cooperation network. The solutions offered are: 1) creating a special website for high school and its various developments containing information on education, activities, and other fields; and 2) providing training on website management as a means of supporting the dissemination of information and a forum for school coordination.

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 — 2023-03-09

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.

Evaluasi Sistem Proteksi Petir Pada Tower Transmisi Saluran Udara Tegangan Tinggi 150 kV dengan Tipe Tower AA

Andi Junaidi — 2023-03-13

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.

Pemilihan Baterai Untuk Kebutuhan Pembangkit Listrik Tenaga Surya Yang Efisien

Novi Gusti Pahiyanti — 2023-03-13

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.

Muhammad Sofyan — 2023-03-13

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 optimizing the solar intensity that solar panels receive, system design optimization requires the most suitable angle of inclination of the solar panels to receive the highest solar radiation. This research was conducted to determine the highest radiation intensity when changing the angle of inclination of solar panels at the PLN Institute of Technology using PV Syst software. The research methodology used in this study is observation and experimentation, specifically direct testing of the influence of an experimental variable, namely changes in the angle of inclination, with certain variations starting from 0° to 65° with variations in the difference every 5°. Data on the results of direct testing at the best angle of 35° are then obtained, and tests are then contrasted using PV syst software. The results obtained in the simulation with the software make it possible to obtain different angles of inclination for each period. The 30° to 35° tilt angle for April to September captures 973 kWh/m2 of radiation, the 0° to 10° inclination angle for October to March captures 854 kWh/m2 of radiation, while the inclination angle from 10° to 13° in one year with an irradiation yield of 1769 kWh/m2.

Muhammad Sofyan — 2023-03-13

Fly ti t one of the pozzolanic materials derived from coal combustion. However, unlike Portland cement, fly ash does not have the capacity to bond. An activator solution, such as Portland cement, is required so that fly ash can have binding capability. Glass trash from industry and homes, in addition to fly ash, may be processed to be utilized as a material that can increase the performance of geopolymer materials since it contains considerable silica (SiO2) and lime (CaO) components. Glass powder was utilized as a fly ash alternative in geopolymer paving blocks in percentages of 0%, 15%, 30%, 45%, and 60%. The compressive strength and water absorption of paving blocks were examined. When the material was 7 days old, the test was performed. The findings revealed that the best compressive strength was found in paving block geopolymer with 45% glass powder variation and 55% fly ash variation, namely 30.67 Mpa, which comprised paving block quality B. The lowest water absorption was reported in paving block geopolymer with 45% variation in glass powder. The paving blocks manufactured in this study were of B quality, according to SNI 03-0691-1996.
