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.

One of the alternative generators in supplying electrical energy is a 3-phase generator made from a 3-phase slip ring induction motor, after which the rotor winding is supplied with a DC source and rotated using a prime mover. The problem arises because of the large % voltage regulation of a 3-phase generator when it is under load. This is because the induction generator has a relatively larger voltage loss when loaded with a certain load compared to a 3-phase synchronous generator. To overcome these conditions, there are several ways that can be used to stabilize the voltage from the generator, namely: setting the excitation current from the generator, setting the connection on the rotor windings (using 2 windings or using 3 rotor windings) and a combination of the two steps above. . Based on the results of experiments that have been carried out, it is known that the method of stabilizing the output voltage by setting the rotor winding connection is less effective than setting the excitation current because it turns out that the results of changing the output voltage are not too significant compared to changing the generator excitation current. In addition, it is also known that the stabilization of the output voltage from an inductive load will require a DC voltage that is greater than when under a resistive load because of the large difference in losses.

The Kebon Agung sugar factory has two power supplies, namely from the PLTU Kebon Agung sugar factory itself and from PLN. There are 3 synchronized generators at the Kebun Agung Sugar Factory, with a power of 4.5 MW on generators 1,2 and 1,6 MVA on generator 3. The difference in power between generators 1,2 and 3 causes frequent interference with generator 3 because it has less power. This Final Project analyzes load sharing and load shedding using MATLAB Simulink R2013a. Through these simulations it is shown the division of the load from each generator during normal conditions or when one generator is released. see the effect of the generator that has been set to speed droop when load sharing conditions, the speed of droop is varied so that it knows the characteristics of the generator that has been set speed droop. In the Final Project, the simulation value and calculation of the speed droop setting value in the Kebon Agung sugar factory is ideal. Because ideally the setting of speed droop in the settings so it is not too sensitive and not too long in responding to changes in load that occur in the system.
