Abstract

The Switch is a tool that everyone knows its use in everyday life. Switch functions as a breaker and connector of an electrical or electronic equipment. Switches are divided into 2 types, namely: mechanical switches and electronic switches. Mechanical switches are made of metal / copper, while electronic switches are made of a semi-conducting material called transistors, which are coupled with other electronic components. The design methode consists of design block design, work system, and design trials. The results obtained are in the form of a prototype electronic circuit called an electronic switch which uses several electronic components such as: resistors, electrolytic capacitors, integrated circuits, diodes, transformers, and relays.

Abstract

Makalah ini membahas tentang sistem PLTS yang terhubung dengan jaringan listrik PLN. Energi surya merupakan sumber energi besar dan tidak akan habis, tidak menimbulkan polusi, aman bagi lingkungan. Pemilihan sistem PLTS yang terhubung dengan jaringan listrik PLN dianggap cocok untuk penggunaan pada daerah yang sudah tersedia jaringan listrik (On Grid). Pada makalah ini perencanaan beban mengambil simulasi beban pada rumah tangga daya 900 VA non subsidi. Berdasarkan hasil perhitungan maka didapatkan nilai efisiensi sebesar 20% menggunakan sistem PLTS.

Abstract

Lagu dihargai karena fitur linguistik, pedagogis, budaya, dan hiburannya dan memang demikian bahan pembelajaran bahasa yang berharga. Pada jurnal ini menggunakan metode bernyanyi serta memastikan efektivitas penggunaan lagu sebagai sarana untuk meningkatkan kosakata bahasa Inggris dan untuk menentukan apakah lagu memengaruhi motivasi belajar bahasa inggris. Yaitu dapat digunakan untuk mengajar dan mengembangkan setiap aspek dari suatu bahasa. Hasil penelitian menunjukkan bahwa lagu memiliki pengaruh positif terhadap kosa kata anak-anak TK. Apapun setting yang digunakan, aural atau aural/visual, hasilnya membuktikan lagu itu cocok untuk gaya belajar yang berbeda lagi menyenangkan, mendorong pengalaman belajar yang positif, dan meningkatkan pengetahuan. Lagu membantu motivasi dan membantu pelajar mengembangkan kecintaan pada pembelajaran bahasa. Siswa termotivasi dengan cara ini adalah imajinatif, kreatif, dan bersemangat untuk belajar dan berhasil.

Abstract

Abstract Transformer oil is very important because it functions as a coolant and also as an insulator. In transformer oil there are dissolved gases that can cause failure of the transformer due to gas failure (fault gas). This research was conducted to determine the condition of transformer oil by analyzing the results of the Dissolved Gas Analysis (DGA) test. The DGA (Dissolved Gas Analysis) test is used to determine the type of failure in a transformer that has been operating for years. The DGA test is carried out by monitoring fault gases such as H2, CH4, CO, CO2, C2H4, C2H6, C2H2, O2, N2 and O2N2 which generally cannot be detected in testing the characteristics of transformer oil. Based on the test results using the Total Dissolve Gas Analysis (TDCG) method condition 1 with the amount of flammable gas 202.845 ppm with the interpretation that the transformer can operate normally. The test results using the Roger's Ratio method on the Power Transformer 1 GI Kotabumi obtained codes 0 0 0. From the combination of the 3 codes above, it shows that the transformer oil is in good condition. The results of the test using the Key Gas method on Power Transformer 1 GI Kotabumi obtained a CO value of 56 percent caused by overheating of cellulose or overheating of solid insulation in the transformer but that value is still far from the threshold Keywords Dissolved Gas Analysis (DGA),Transformer oil, Roger'r ratio method, KeyGas

Abstract

Drop tegangan di wilayah Tulang Bawang dan Mesuji sudah mencapai level – 50 percents dari tegangan nominal. Sedangkan berdasarkan SPLN T6.001 tahun 2013 tentang Tegangan Tegangan Standar disebutkan bahwa tegangan tertinggi dan tegangan terendah perbedaannya tidak boleh lebih besar kurang lebih 10 percents dari tegangan nominal sistem. Drop tegangan terjadi karena panjang penghantar jaringan terlalu panjang dan beban feeder besar di ujung jaringan serta terlambatnya pembangunan gardu induk Mesuji. Perbaikan tegangan pada sistem kelistrikan di wilayah Tulang Bawang dan Mesuji disimulasikan menggunakan Aplikasi ETAP dengan memanfaatkan fungsi Load Flow Analisis sehingga diperoleh hasil aliran daya pada sistem kelistrikan tersebut. Simulasi dilakukan pada dua kondisi yaitu kondisi sebelum dan kondisi setelah Mobile Substation 150/20 kV beroperasi pada sistem kelistrikan Tulang Bawang dan Mesuji. Dari hasil simulasi dengan Aplikasi ETAP dapat diketahui perbaikan tegangan pada sistem kelistrikan Tulang Bawang dan Mesuji. Sehingga apabila hasil simulasi dianggap layak, maka pengoperasian Mobile Substation 150/20 kV dapat dilaksanakan

Abstract

Abstract — To maintain battery performance, it is necessary to have a battery monitoring system that functions to determine several parameters in the battery, such as voltage, current, capacitance and battery capacity. The technology for knowing battery capacity is often known as state of charge (SOC). State of charge (SOC) is the ratio of the remaining energy to the maximum energy capacity of the battery. State of charge values ​​are often expressed in percentage form, 0 percent -100 percent. Estimating the value of the state of charge is quite important in battery monitoring technology. The lead acid battery testing process is carried out for 10 hours or 36000 seconds, both in the condition of discharging and charging the battery. In this study, the initial State of Charge (SOC) value for the battery is given, namely the upper limit and lower limit. The upper limit value for the initial State of Charge (SOC) is 100 percent, while the lower limit value is 20 percent. In the process of discharging the lead acid battery, it can be seen that the current value when discharging is stable at 1.2 Amperes. The charging current value is very constant, namely at 0.425 A. Meanwhile, the charging voltage value is also constant at 12.215 V. Keywords — State of Charge, Lead Acid, Coulomb Counting, Matlab.
