Perumahan Giripalma mempunyai sumur air yang dikelola sendiri oleh warga Perumahan. Penggunaan air dari sumur ini berbayar atau dengan kata lain warga Perumahan berlanggan. Warga berlangganan dimaksudkan agar pemakaian air tidak boros, dengan demikian diharapkan agar sumur tidak cepat habis airnya. Air dari sumur ini dinaikan ke tandon dengan menggunakan motor pompa listrik tiga fasa 380V. Sampai saat ini motor pompa dihidupkan dan dimatikan dengan cara manual, yaitu apabila apabila air di tandon sudah habis maka pompa dihidupkan, sampai tandon air penuh. Ada petugas sendiri yang menghidupkan dan yang mematikan pompa. Kelemahan dari cara manual ini, petugas sering bolak-balik untuk melihat apakah tandon sudah penuh atau belum, karena kalau tandon ditunggu sampai penuh maka butuh waktu lama, padahal dengan waktu yang lama ini petugas bisa mengerjakan pekerjaan yang lain.Untuk memudahkan dan meringkankan pekerjaan petugan maka kami membuat kontrol pompa air ini secara otomatis, yaitu apabila tandon kosong maka otomatis pompa bekerja, dan apabila tandon penuh pompa maka berhenti. Selanjutnya untuk memantau kontrol pompa air ini tidak dipercayakan kepada petugas lagi tetapi dipercayakan kepada Karang Taruna Perumahan Giripalma, agar Karang Taruna bertanggungjawab terhadap lingkungan hidupnya, dan untuk kerampilan mereka di masa mendatang.

The timber industry in the process of cutting is done several types of sawing machine that has been designed in accordance with the needs of use facilitatein the process of cutting. Besides the saw machine simplifythe work given the limited ability of the power human beings either in the form of materials to be cut and safety work of employees. If the company is just a racket manpower is very limited, so to increase that efficiency desirable will be difficult to achieve, therefore required appropriate technology to help improve the eficiency. Technology that can help is to use shawmill machine automatically. In the process of sawing there are several types of sawmill such as: disc saw, bandsaw, in this case the writer uses bandsaw, adjusted with observation data with the power of 22 Kw saws and at the train with power of 1.5Kw. In the manufacture of this control the autor uses the HMI program in the process of controlling the engine from a distance, and operates it. Inside the HMI can be seen on a running machine and a machine that is a trouble.

One of the causes of the reduced life of the transformer is due to loading. From the eleven transformers, it can be seen that there are different loading variations, it is expected that the transformer life will remain at normal age. IEC 60354-1, 1991 stipulates the normal life of the transformer is 20.55 years. The research method used is to perform calculations using the long-time method and 24-hour daily data by calculating the loading at the time of LWBP and WBP on a 20 kV distribution transformer. Analysis of the calculation results revealed that the normal condition of the transformer P1385 (68.66 %) winding temperature at LWBP 67.47°C and when WBP 69.45°C compared to transformer P0032 with overload conditions (120.91%) winding temperature when LWBP 60, 88°C and at WBP 119.51°C. From the data on the lowest loading on the eleven transformers, namely transformer P0527 (41.69%) it is obtained that the estimated real aging age is 0.125 and the estimated age of the P0527 transformer is >20 years. Compared to transformer P0032 (120.91%), the estimated real aging age is 12,0003 p-u and the estimated age is less than 20 years or 9.5 years. Loading above 100% on the transformer based on the standard IEC 60354-1, 1991 if it takes place continuously will cause heating of the transformer windings which can cause the shrinkage process in the life of the transformer to be faster.

Analisis Rencana Pemasangan Transformator Sisipan Untuk Mengatasi Overload dan Drop Voltage pada Penyulang Selogabus PT. PLN (Persero) ULP Bojonegoro Kota Sukamdi; Harrij Mukti K.; Muhammad Hadyan Farizan; Muhammad Rafid Faiz Firmansyah

Transformers MA164 (250 kVA) and MA267 (250 kVA) have experienced overload (LoadMA164 = 102% and LoadMA267 = 111%) based on the loading standardization, namely SE DIR PT. PLN (Persero) No.0017/2014 (≤ 80%). The MA164 and MA267 transformers also have the farthest customer end voltages of 187 V (ΔVMA164 = 23%) and 189 V (ΔVMA267 = 22%) which do not comply with SPLN standard No. 1 Th. 1995 (+5% and -10%). An effective solution is to install an insert transformer because MA164 and MA267 cannot be uprated and cannot be broken by the JTR load. For planning the installation of the insert transformer it is necessary to carry out load forecasting, determination of the capacity of the insert transformer, division of the line of the farthest customer parts, determination of the location and selection of distribution substation accessories.The MA164 insert transformer (160 kVA) is installed at a distance of 416 m from the MA164 Transformer with a loading of 47%, while the MA267 insert transformer (200 kVA) is installed at a distance of 255 m from the MA164 Transformer with a loading of 47%. After installation the insert transformer MA164 transformer has a load of 77% and a end voltage of 211.9 V (ΔVMA164 = 9%), while the MA267 Transformer has a loading of 62% and an end voltage of 212.7 V (ΔVMA267 = 8%). With the appropriate conditions, the transformer can function properly and the customer's electrical equipment can function normally.

This study aims to design a PWMtype charger controller, to discover the performance of the PWM type controller, to determine the compatibility of the PWM type charger controller and MPPT, and to analyze the performance of the PWM type charger controller in the PLTPH in JLC. The method of analysis of this study uses field data and is tested on the PWM type charger controller and the MPPT type charger controller. From the data, the two charger controllers are compared. The results showed that the PWM and MPPT charger controller performed well to cut off the load current when the battery was full, the PWM and MPPT charger controller performed well to disconnect the load when the battery began to run out. The PWM and MPPT charger controllers have the same charging speed, and the MPPT charger controller has good efficiency in the PLTPH system.

A Variable Speed Drive (VSD) is a device that regulates the speed and rotational force or torque of mechanical equipment. VSD improves efficiency by allowing the motor to operate at the ideal speed for each load condition. In many applications, VSD reduces the electricity consumption of the motor by 30-60%. The energy-saving potential of electric motors is significant as motor systems account for more than 60% of the power consumed by industries. It is due to these advantages that VSD can be used to control the speed of compressor motors, thereby enhancing the performance of the compressor. A compressor motor is a device that compresses air and increases its pressure. To compress air, the compressor requires a driving force, and one of them is the motor. When the output air pressure of the compressor exceeds a certain value, the relief valve will open automatically, allowing the air to remain in the tank even when the motor is still running. During compressor operation, the motor is always started with a high starting current, resulting in high power demand. Therefore, control of the compressor motor is necessary.
