Abstract

Automatic Transfer Switch (ATS) adalah suatu rangkaian yang mampu memindahkan beban dari sumber listrik utama ke sumber listrik cadangan. Apabila kemudian PLN kembali normal selanjutnya ATS bertugas untuk mengembalikan jalurnya dengan memindahkan switch kembali ke sisi utama. Suplai daya utama dari PLN tidak selamanya berkesinambungan, suatu saat pasti terjadi pemadaman yang dapat disebabkan oleh perawatan secara berkala atau pun gangguan pada pembangkit di sistem distribusi dan sistem transmisi. Maka untuk mengatasi hal tersebut diperlukan back up daya yang berupa generator. Kendala dalam menggunakan generator ini adalah ketika suplai daya dari PLN terputus operator akan membutuhkan waktu yang lama dalam menghidupkan generator, inilah mengapa kita membutuhkan alat bantu otomatis untuk mempermudah operator yakni ATS. Alat yang dibuat ini dilengkapi dengan Programmable logic control (PLC), PLC ini merupakan sistem kontrol utama untuk alat yang akan dibuat sebagai kontrol otomatis sehingga memudahkan dalam pembuatan, instalasi, dan perawatan.Kata kunci : ATS, PLC, Generator

Abstract

This research aims to provide empirical evidence regarding the effect of working capital, liquidity, Leverage and activity on profitability in health sector companies listed on the Indonesia Stock Exchange. Specifically, working capital is measured by Working Capital Turnover (WCTO), liquidity is measured by Current Ratio (CR), Leverage is measured by Debt to Equity Ratio (DER) and activity is measured by Total Asset Turnover (TATO). The sample selection was carried out using purposive sampling method, based on the criteria that have been determined, a sample of 12 health sector companies on the Indonesia Stock Exchange (IDX) during the 2019-2023 period was obtained. Based on the results of hypothesis testing, it shows that working capital has a significant effect on profitability, liquidity has a significant effect on profitability, Leverage has an effect on profitability, activity has an effect on profitability in health sector companies listed on the Indonesia Stock Exchange for the period 2019 to 2023.

Abstract

Water is one of the basic necessities used by living things on this earth. Along with the population growth with climate change, there are several cases of water crisis in Java and Bali, especially in the dry season. The purpose of this research is to project water demand and availability based on climate change scenarios, develop an analysis model for the impact of climate change on the water sector based on the water balance, and calculate environmental economic losses resulting from water deficit losses. The type of scenario used in climate analysis is RCP (Representative Carbon Pathway) 4.5 with two types of models. Provinces experiencing very critical water conditions in the 2021-2050 period using the CSIRO model are DKI Jakarta, East Java and Bali, with water criticality indexes of 296.25%, 113.88% and 123.64%, with a water deficit loss of IDR 1.2 billion, IDR 7.93 billion and IDR 0.87 billion. Whereas with the MIROC model, the areas that have very critical water conditions are DKI Jakarta Province with a water criticality index of 220.36%, with a water deficit loss of IDR 0.42 billion.
