Fire is an event where small fires or large fires start that we don't plan and cause a lot of losses around it. Fire is a tragedy that often occurs in Indonesia. There are various factors that can trigger a fire including human negligence, natural factors and intentional factors. One type of fire that often occurs in Indonesia is a type of fire caused by human negligence, namely house fires where house fires can cause large losses, both material losses and fatalities. In 2020-2022 there will be lots of house fires caused by explosions of LPG gas where the initial cause of these explosions was not caused by gas cylinders but caused by devices from these gas cylinders such as hoses and regulators. Through this incident, we need a fire detection system that can detect the presence of leaking gas smoke or fire in the house. In this study the authors will create a fire detection system using Arduino Uno R3 as a microcontroller connected by an MQ5 gas sensor as an input that can detect the presence of methane and butane which will then issue an output in the form of a red LED, a green LED and a 5v buzzer as a reminder alarm.

PT. Kalbio Global Medika (KGM) is one of the first and pioneer biopharmaceuticals in Indonesia and is a subsidiary of PT Kalbe Farma, Tbk., a leading healthcare provider in Indonesia and Southeast Asia. Liquid pharmaceutical waste from the results of drug production activities will be collected and processed in the Killing Tank System machine before being sent to Lippo's wastewater treatment plant so that the hazardous substances contained do not have a negative impact on the environment. There are 2 methods to kill bacteria in production waste water, namely by the method of ozonation and heating with steam. Currently, when the Killing Tank is in Steam mode, someone has to wait for 2 hours during the Holding process. When it's finished, the steam mode wastewater treatment process must be turned OFF manually by rotating the selector switch to stop the supply of steam from the boiler to the Killing Tank. If the process continues for more than 2 hours, there will be a waste of steam used during the wastewater treatment process. This research aims to provide a solution to this problem, namely to simplify and increase the effectiveness of the Killing Tank machine. By adding the Omron H3CR-A8 timer to the Killing Tank, it will automatically stop the steam supply from the boiler according to the set time.

High voltage substation is a crucial facility in the electric power system. This facility functions to distribute electricity from power plants to consumers through complex equipment such as transformers, switches and circuit breakers. The goal is to ensure a stable and secure supply of electricity. One of the important devices in a substation is the Power Disconnector (PMT), whose job is to cut off the flow of electricity in the event of a disturbance or overload on the electrical network. PMT has an important role in maintaining the security and availability of electricity supply in the power grid. Therefore, damage to PMT is very detrimental to the operation of the electric power system, so it is necessary to test it regularly to ensure its safety and controllability in operation. In this study, the simultaneity test was only carried out, namely by comparing the values obtained with the standard values for each test listed in SK-DIR 0520-2014. The test results show that the delta time values obtained both at open and close are each under 10ms, so it can be concluded that the PMT installed in transformer bay-1 of the Tasikmalaya Baru 150kv substation is still in safe condition and feasible to operate according to standards.

Di Indonesia, dari segi teknis, tenaga listrik dibagi menjadi 3 yaitu Pembangkitan, Transmisi dan Distribusi. Ketiga komponen besar tersebut merupakan hal utama dalam pemanfaatan energi listrik agar dapat dikonsumsi oleh seluruh masyarakat. Agar dapat dikonsumsi oleh masyarakat, diperlukan penyaluran tenaga listrik dari pembangkit listrik ke gardu distribusi. Sistem jaringan ini terdiri dari saluran transmisi SUTET 500-275 KV, SUTT 150-70 KV dan jaringan distribusi. SUTT adalah saluran tenaga listrik yang menggunakan konduktor telanjang di udara dengan tegangan di atas 35 kV sampai dengan standar 245 kV di bidang ketenagalistrikan. SUTT adalah sistem distribusi tenaga listrik dari pembangkit listrik skala besar ke gardu induk (GI) langsung ke gardu konsumen. Saluran transmisi sering terganggu terutama sambaran petir (lonjakan) karena sifatnya yang terbuka. Jika saluran transmisi ini terganggu, saluran lain seperti gardu induk dan saluran distribusi akan terganggu dan rusak. Petir yang menyambar kabel tanah saluran transmisi menyebabkan tegangan lebih berupa gelombang berjalan yang menjalar dari titik sambaran ke menara transmisi. Diperlukan fondasi yang baik di kaki menara. Salah satunya dengan ground rod yang dapat mengurangi tahanan pentanahan pada kaki-kaki tower secara paralel. Dengan harapan dapat meminimalisir gangguan yang sering terjadi akibat petir.
