<p><em>Housing employees of PT. Cipta Lestari Sawit Bumirejo Estate in block B55 is located in the middle of an oil palm planta- tion, so the state electricity company network cannot reach the housing. So, this housing uses a diesel power plant (PLTD) as a source of electricity, its operational hours are limited and it also causes noise and air pollution. From this problem, one suitable solution is to build a solar power plant (PLTS) that does not cause noise and air pollution and its operating hours can be adjusted as needed. In planning PLTS, there are main components that need to be calculated including Solar Panels, Solar Carger Controller (SCC), Batteries, and Inverters. For planning PLTS in employee housing block B55 PT. Cipta Les- tari Sawit Bumirejo Estate requires 273 solar panels with a capacity of 300 wp per unit, 53 solar charge controllers (SCC) with a capacity of 80 amperes, 34 batteries with a capacity of 2000 Ah per unit, and 68 units with a capacity of</em> <em>6000 watts per unit. to supply electricity to 70 houses and 8 street lights.</em></p>

The maximum output voltage of the audio amplifier is limited to the magnitude of the power supply voltage of the power transistor or the operational amplifier on the final amplifier. This limits the maximum power of the audio amplifier output. The way to enlarge the output power of the audio amplifier without increasing the voltage is the bridge method or bridged modes. With this method a bridge amplifier will be generated. This Bridge Amplifier is also known as Bridge-Tied Load (BTL) or Bridged Transformerless. The principle of Bridge Amplifiers is to use a pair of final amplifiers whose outputs have opposite phase each other. There are 3 ways to make a pair of power amplifiers have opposing phases: with internal modification, with an audio transformer (phase splitting audio input transformer) and with a simple active phase reversal splitter circuit). This paper will discuss Bridge Amplifiers with simple phase inverting circuits. A pair of audio power amplifiers using two TDA2050 chips which are operated at ± 19 Volt supply voltage. The phase inverting circuit using IC TL072. Sinusoidal signal with an amplitude of 200 mVp and a frequency of 1 KHz is used as an input signal. The results to be observed and measured are gain, input, output and bandwidth of the bridged amplifier compared to the usual amplifier

<em>T<em><span>The induction motor is the electric drive for industry so special attention is needed for maintainance and control system. Induction motors pulling high starting currents at starting. Various starting methods have been developed to overcome this problem, one of which is the Direct On-Line starting method. This method is the most common method because it is the easiest and cheapest to use, but there is high inrush current arround 6-8 times the nominal current will pulled by induction motor when using this method. This starting current can cause several disturbances, both from the electricity network, damaging the motor and can cause fatal losses to the electric power system.This research discusses the application of the Soft Starter starting method to a 3-phase induction motor to reduce the high starting current pulled by a 3-phase induction motor. The induction motor used in this study is a squirrel cage rotor type with 4kVA power, a rotational speed of 1430 r.p.m, a frequency of 50 Hz, and a voltage of 380 V.

MATLAB SIMULINK is used to simulate the application of the soft starter starting method on a 3-phase induction motor.The results prove that the Soft Starter method is successful in reducing staring currents when compared to the Direct On-Line method. When using the Direct On-Line method the starting current is 77.29 78.80 A, when using the sine-triangle soft starter method the starting current is 60,46 61,46 A, and when using the sine-sawtooth soft starter method. starting 59,96 60,60 A. However, at steady state conditions, the Direct On-Line rotational speed is better than the Soft Starter because when using the Soft Starter method the voltage is cut. Soft St</span></em></em>

<p><em>Aerator has function to supply the dissolved oxygen in the water is very important for the survival of fish, therefore the</em><br /><em>aerator is required to be on for 24 hours. However, due to depending on PLN electricity, when there is a power outage for a</em><br /><em>long period of time, the aerator can't supply dissolved oxygen into the pond and the oxygen supply in the pond will drop</em><br /><em>drastically. This is dangerous because it can threaten the survival of ornamental fish. Therefore, an energy supply system is</em><br /><em>needed that can supply electrical energy to the aerator to replace the dependency electricity from PLN. This tool is designed</em><br /><em>to use a power supply from solar panels so that it is not affected in the event of a PLN power outage, and can always supply</em><br /><em>dissolved oxygen levels for the survival of ornamental fish. In addition, this tool is also equipped with a monitoring system</em><br /><em>based on the Nodemcu ESP8266 Microcontroller which is displayed via the Thingspeak server. The monitoring system used</em><br /><em>in this tool uses a PH sensor and a temperature sensor. The use of PH sensors and temperature sensors because the level of</em><br /><em>acidity (PH) and temperature are one of the parameters of water quality other than dissolved oxygen. When the aerator is on,</em><br /><em>the information on the pool water will be read through the PH sensor and temperature sensor.</em></p>

<p><em>Water pollution often occurs due to the disposal of household waste (solid waste and liquid waste) as well as industrial </em><br /><em>waste, small industry and non-organic waste.

The</em><br /><em>purpose of this research is to make a device that can determine the condition of river water, which is polluted or not from a</em><br /><em>long distance. The method used in this study is by taking samples from river water that can represent polluted and unpolluted,</em><br /><em>then data is taken from these samples which are then processed so that their condition can be known.

Dalam Alkitab, manusia diciptakan segambar dan serupa dengan Allah atau disebut dengan Imago Dei. Allah menciptakan manusia dan memberi kuasa kepada manusia supaya merawat dan  menjaga seluruh ciptaan-Nya. Namun, kuasa yang diberikan Allah membuat manusia merasa berhak untuk melakukan apa saja terhadap ciptaan-Nya. Dan tidak sedikit juga manusia salah memahami konsep segambar dan serupa dengan Allah yang mengaitkannya dengan kedagingan. Berdasarkan tulisan  ini penulis akan membahas penciptaan manusia segambar dan serupa dengan Allah (Kejadian 1 : 26-28). Penulis bertujuan untuk memberi pemahaman konsep (Gambar dan Rupa) yang tidak sama dengan kedagingan dan pemahaman tentang kuasa yang diberikan Allah serta makna teologis dalam ayat tersebut.

Seiring dengan pesatnya perkembangan pendidikan, dan tuntutan mengikuti perkembangan teknologi, maka sekolah perlu untuk terus berinovasi dalam meningkatkan pelayanan serta interaksi yang lebih komprehensif dengan wali siswa pada khususnya dan masyarakat pada umumnya. Berangkat dari kebutuhan tersebut, sekolah perlu mempunyai media yang bisa digunakan sebagai sarana interaksi antara pihak sekolah dengan masyarakat dan sebagai sarana eksistensi sekolah di dunia maya. Sistem informasi sekolah sekarang ini sedang menjadi tren di dunia pendidikan dan sistem informasi sekolah mendapatkan perhatian, tanggapan yang sangat bagus dari berbagai pihak baik itu dari tenaga kependidikan, siswa dan juga masyarakat serta keberadaan sistem informasi sekolah pada saat ini memang sangat penting.
