Sistem tenga listrik dapat dikatakan memiliki keandalan yang tinggi apabila sistem tersebut menyediakan pasoka energi listrik yang dibutuhkan konsumen secara kontinyu, pada kenyataannya permasalahan yang dihadapi penyaluran sistem tenaga listrik adalah gangguan kedip tegangan (voltage sags) yang diakibatkan gangguan hubung singkat pada sisi penyulang, Penelitian ini menganalisa kedip tegangan yang terjadi pada Saluran Udara Tegangan Menengah (SUTM) 20 KV akibat gangguan hubung singkat tiga phasa berdasarkan jenis konduktor yang digunakan pada sisi penyulang, kajian dilakukan dengan asumsi sistem penyaluran tanpa gardu hubung dan menggunakan konduktor AAC dan AAAC. Hasil penelitian menunjukan besar magnitud arus ganggan hubung singkat tiga phasa pada kedua konduktor menyerupai disepanjang penyulang, sedangkan besar kedip tegangan yang terjadi disepanjang penyulang menyerupai jika terjadi gangguan dititik 0% - 10% panjang penyulang dan terdapat perbedaan besar kedip tegangan apabila gangguan terjadi diatas 25% panjang penyulang. Hasil dari penelitian ini dapat digunakan untuk keperluan penyetelan proteksi pada sisi penyulang dalam menjaga keamanan dari penyaluran energi listrik.

The need for a charge controller for the use of electrical energy sourced from solar panels and DC generators is very necessary for the purposes of the battery function as electric power in the inverter which functions as a voltage source. Usually the battery is used for inverter purposes in meeting household electricity needs as a substitute for PLN. The charging process will occur if the output voltage from the DC voltage source is higher than the battery voltage to be recharged. In this study, the charging process is based on PWM settings, and consists of 2 types, namely boost mode and float mode which are distinguished from the duty cycle setting. The voltage reading on the voltage divider sensor using a resistor has an error of less than 6.22% at the source terminal, and 6.89% at the battery. However, the charging process is able to provide an average voltage of 13.14 Volts on the battery (12 Volts), so that the charging process can run well.

The need for clean water is currently the concern of many people, especially brackish water that occurs from land water discharge and the mixing of sea water with fresh water. Jambi Province in particular, there are several areas downstream of the river where the chemical/physical properties of water are blackish brown and are brackish water content, with this water content it is necessary to find a way to reduce the level in order to get water that is suitable for use by the community. The purpose of this study was to separate the content of brackish water using the plasma DBD (Dielectric Barrier Dicharge) method. Where the plasma concentration of DHF affects the level of brackish water related to Ph, TDS and Salinity. From the results of research on the DHF Plasma process for purification / separation of parameters of brackish water content from parameters of Ph, TDS and Salinity, there is a change or decrease in each of these parameters at each change in the length of the test time (5 minutes, 10 minutes and 15 minutes).

Automotive workshop activities generate waste water requiring some treatments before being discharged into receiving water surface. One of the wastewater treatment methods for is the electrocoagulation method. This study aims to observe the effectiveness of the electrocoagulation method in treating wastewater from automotive workshop activities. Observations were limited to the effect of current density on the efficiency of removal of pollutants from wastewater from automotive workshop activities, including pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) ,oil and grease Current density were varied into 62 A/m2, 53 A/m 2, and 31 A/m 2. The results showed that the highest removal efficiency for the pollutant parameters BOD, COD, and oil and grease respectively were 91.53%, 94.90%, and 81,38% at current density 62 A/m 2. The electrocoagulation process was strongly influenced by the current density, where the higher the current density, the higher the removal efficiency.

Photovoltaic (PV) is an environmentally friendly renewable energy source. Photovoltaic when connected directly to the load, the power delivered to the load is not optimal. Therefore it is important to get maximum power from the PV system to increase efficiency. This study presents an MPPT system using the Incremental Conductance (IC) algorithm to analyze PV systems installed in parallel and installed in series using 3 PVs. This IC algorithm works by monitoring the current gradient to determine the direction of voltage change and providing a change in derivative voltage so that it can determine the speed of delivery. From the results of the study, the average power using 3 PVs installed in series was 95.4% and using 3 PVs installed in parallel was 88.44%. The algorithm (IC) has a faster response in tracking the maximum power point when installed in parallel even though its efficiency is lower. However, current variations when there are changes in solar radiation tend to be constant as long as the temperature conditions are close to stable.

Photovoltaic (PV) is an environmentally friendly renewable energy source. When Photovoltaics are connected directly to a load, the power delivered to the load is not optimal power. Therefore, it is important to get maximum power from the PV system thereby increasing efficiency. Various maximum power point tracking (MPPT) techniques of PV systems are proposed, such as Perturb and Observe (P&O) algorithm. MPPT techniques are usually limited to uniform weather conditions. This research presents an MPPT system with a series of DC-DC Boost converters under conditions of changes in solar irradiation, each change is assumed to last 5 hours and a temperature of around 250C, while the amount of solar irradiation is 300 W/m2, 500 W/m2, 700 W/m2 and 1000 W/m2. From the results of research carried out with the help of MATLAB simulations, it was found that the average efficiency was 95.6% and obtained low oscillation MPP tracking as well as fast and dynamic response during stable weather conditions.
