The protection system is essential in the 20 kV distribution network system. The 20 kV equipment control system is supplied from 2 sources: PT (Potential Transformer) and DC voltage supply (Battery). If the protection relay and mechanics do not get a DC voltage supply, it will have an impact on the equipment not being able to trip when there is a disturbance in the network. There is no DC voltage supply due to battery failure or damage. For this reason, it is necessary to operate the tool manually, which results in the normalization process taking longer because it takes time and long distances, so the duration of outages is even greater. In this study, a monitoring system for the battery of the equipment will be made where previously observations were made about the need for this tool. The method used by the tool uses the blynk application as a receiver of direct voltage and temperature measurement reports that are connected to the gsm module. As a microcontroller processes, Arduino Nano commands from intelligent phones, generating a measurement report from the battery. GSM SIM 900 module as a data receiver and sender in the system. This tool is easy to apply to the system because it does not require a sufficient additional voltage source from the battery. The results of this study become a solution for companies to improve their 20 kV. distribution network system.

Warehousing or warehouse is a very important part to support the smooth operation of the upstream oil and gas industry. Work accident is one of the risks that can cause operational disruptions in the warehouse and can cause delays in the process of supplying and delivering tools and materials needed for oil and gas production activities. More than 145,000 people work in 7,000 warehouses, where the fatal injury rate for warehousing is higher than the average for all industries (OSHA, 2004). Therefore companies are required to have a system that regulates hazard identification, risk assessment and risk control or commonly known as Hazard Identification, Risk Assessment and Risk Control (HIRARC). Currently, PT Borneo Mitra Bersama currently has a project at PT Pertamina Hulu Mahakam, namely the Warehouse Support Project. Based on PT BMB's preliminary observations there has been no HIRARC implementation related to the project's operational activities, while the project has a high risk value based on the tender documents. In this study using a qualitative approach. The study design in the research used was based on the ISO 31000: 2018 standard with a semi-quantitative risk analysis technique, by taking informants using a purposive sampling technique, totaling 6 people. The research results show that the risk assessment in PT Borneo Mitra Bersama's warehousing operations has 33 risks identified with the results of the risk evaluation level obtained at the initial risk, namely 6 (18.18%) risk priority level 3, 34 (72.72%) substantial level risk and 11 (33.33%) very high level risk, while the risk evaluation results obtained for residual risk are 24 (9.09%) acceptable level risk and 9 (27.27%) priority 3 or tolerable level risk risk.

The course Algorithms and Programming in the Informatics Engineering study program is given in the first and second semesters, as this course is a scientific course that serves as a basis for advanced programming courses in higher semesters. It is often the case that intelligent graduates obtain good academic grades during their studies and become outstanding students, but when working in their field of expertise, their performance is not as good as graduates who had lower academic grades. Success is not only determined by intellectual intelligence (IQ), but also by other types of intelligence. Intellectual intelligence or cognitive intelligence is one type of intelligence, while non-intellectual intelligence includes other types of intelligence outside of cognitive intelligence. One of this non-intellectual intelligence is emotional intelligence. Intellectual intelligence and non-intellectual intelligence play equally important roles in supporting individual success. This research discusses the analysis of the effect of emotional intelligence on the level of understanding of algorithms and programming using the linear regression method implemented with an application. The sample taken is students of the Informatics Engineering study program in the third and fourth semesters. With the results of the influence of emotional intelligence on the understanding of Algorithms and Programming, it can provide a solution to improve students' understanding of the Algorithms and Programming course and other computer courses in the scientific field of the Informatics Engineering study program. The application is created using the Python programming language.
