Abstract

Design of an Auto Transfer Switch (ATS) Panel on a Hybrid PLN Sistem – Timer Switch Based Solar Panel. Along with the times, modern technological equipment that is present today is very helpful for human life. Using the MCB, timer, contactor, panel box. The results of the study obtained electric current data from PLN when using a lamp load of 5, 10, 15, 20, 25 watts respectively, namely 0.03, 0.06, 0.09, 0.12, 0.15 A with a calculated voltage of 166 Volts. The current from the solar panel when using a light load of 5, 10, 15, 20, 25 watts respectively is 0.03, 0.06, 0.09, 0.13, 0.16 A with a calculated voltage of 166, 153 and 156 Volts. The lag time for moving from PLN to solar panels is 1.60 seconds. Savings using this hybrid sistem is 19,468 rupiah.

Abstract

Kekuatan lengkung material merupakan kemampuan suatu material untuk menerimah tegangan tanpa menyebabkan material menjadi patah.. Untuk mengetahui lengkungan material lambung kapal melalui proses penekukan dan untuk mengetahui kekuatan lengkung maksimum material pada lambung kapal yang sesuai dengan standar. Bahan material pada pengujian ini menggunakan plat baja ST.40 karbon rendah dengan ketebalan 8 mm. Spesimen menggunakan tandar ASTM baja ST 40 disebut dengan istilah AISI 420, Jenis pengujian ini menggunakan pengujian lengkung untuk mengetahui kekuatan baja. Hasil pengujian kekuatan lengkung ST.40 specimen A didapatkan rata-rata kekuatan lengkung maksimum sebesar 606 N/mm2, sedangkan spesimen B didapatkan rata-rata kekuatan lengkung maksimum sebesar 785 N/mm2. Kesimpulan Dari 2 (dua) pengujian spesimen nilai rata-rata kekuatan lengkung maksimum yang mendekati standar BKK yaitu specimen A.

Abstract

The forward reverse circuit is an electric motor control circuit whose function is to provide current to the electric motor or elmot. So that the electric motor can rotate to move forward and backward to move a machine.. The aim of this research is to determine the design, working methods and test results on a 3 phase electric motor forward reverse circuit.The data collection method for this research is observation, namely collecting information from observations or proving the truth of a research design being carried out, the literature study method looking for theoretical references that are relevant to the problem in accordance with the writing of the final assignment, the experimental method is carrying out an experiment to observe the process and The results can then be drawn to conclusions and the waterfall method is a design development model where each stage is carried out sequentially from top to bottom.The results of this study obtained a design by selecting tools and materials for the forward reverse circuit on a 3 phase electric motor. Electric current, obtained from the forward system circuit in the R phase 05.65 A, S phase 06.28 A and T phase 06.09 A and the voltage obtained in the R to S phase 396.5 V, S to T phase 400.3 V and the T to R phase is 387.5 V and the power produced is 811.1278 watts and the speed produced by a 3 phase electric motor using a forward system circuit is 1284 rpm. Electric current, obtained from the reverse system circuit in the R phase 06.07 A, S phase 05.85 A and T phase 06.02 A and voltage, obtained in the R to S phase 400.5 V, S to T phase 398.8 V and the T to R phase is 389.5 V and the power produced is 815.2452 watts and the speed is produced by a 3 phase electric motor using a reverse system circuit of 1278 rpm.
