This paper presents how to increase the effectiveness of automobile manufacturing in terms of production machine performance. Automobile companies are one of the many industries that exist in various countries. This is because automobiles are transportation products that are widely used both for the purpose of transporting people and goods. Poor production machine performance will disrupt internal productivity to the point that it will affect the stability of industrial profits. One of the factors causing poor engine performance is due to predictive maintenance analysis activities that are still not optimal. SCADA system development will focus on monitoring equipment before it becomes abnormal (predictive maintenance) in real time. The monitoring and control method is carried out automatically by using sensors for data retrieval and a programmable logic controller as a remote terminal unit. Then, data will be sent to the server via CC-Link IE Field Communication and later be recorded and analyzed through the SCADA display. The results of research optimizing engine performance using the SCADA system are effective, with an increase in engine performance of 96.2% for downtime and 97.0% for frequency trouble.

Various regulations and standards have been issued by various authorities to support and increase the efficiency of energy use and manage energy conservation activities. Energy conservation is the obligation of all parties, including from the side of energy users in buildings, including one of them is the ITERA Public Lecture Building which is used mostly for classrooms, but there is no data on the quality of the lighting system. Therefore, this study aims to analyze the lighting system (energy consumption and lighting level) on the 3rd Floor of the ITERA General Lecture Building using the energy audit method. From the results of the study, it was found that the total energy consumption in the artificial lighting system (lamps) was 798.72 kWh/month, and the lighting level met the minimum limits of SNI 6197-2020, but out of 11 classrooms there were 7 rooms that were too much larger than SNI 6197-2020. So that the saving opportunity that can be done is to change the awareness of room energy users by reducing the length of time the lamp is used and prioritizing the use of natural light in the morning and afternoon so that it can save energy use by up to 34%.

Kabel diproduksi dengan metallic sheath yang merupakan selubung metalik untuk ketahanan terhadap benturan agar terhindar dari kerusakan mekanis. Ketika kabel dialiri listrik, terjadi tegangan induksi dari konduktor inti ke metallic sheath yang ditanahkan. Studi kasus ini dilaksanakan di PLTU FTP 2 Lombok, dimana saat switching capacitor bank beroperasi maka terjadi transien tegangan secara cepat dan dapat mengakibatkan kenaikan suhu serta kegagalan jangka panjang pada kabel transmisi. Sheath voltage limiter perlu ditambahkan pada salah satu ujung kabel dengan instalasi teknik single point bonding dengan maksud untuk mencegah tegangan induksi pada selubung kabel. Sheath voltage limiter merupakan perangkat pelindung dari lonjakan tegangan yang terhubung antara metallic sheath dan ground. Simulasi ATP-EMTP (Alternative Transients Program – Electromagnetic Transients Program) digunakan untuk mengetahui keefektifitasan shealt voltage limiter dalam mereduksi nilai tegangan induksi pada metalic shelath cable. Hasil dari simulasi menunjukan dengan pemasangan SVL di sisi pembangkit dapat mereduksi nilai tegangan induksi pada kondisi normal sebesar 87.2% dan saat terjadi transien sebesar 89.58% - 94.53%.

Lube oil cooler fan at Combine Cycle Power Plant (CCPP) Block 1-2 PT. PLN Indonesia Power Priok is used as a heat exchanger to reduce the temperature of the lubricant that has passed through the system so that it can return through the system at a lower temperature. CCPP Block 1-2 often experience Start-Shutdown units due to requests from the PLN load regulator, therefore the lube oil cooler fan often continues to operate even though the lubricant temperature is low during the Shutdown (RS). The lube oil cooler fan optimization program is an activity to turn off one fan during the reverse shutdown unit and turn off all the fans manually by the operator when the lubricant temperature is below 42oC and then recorded for documentation. This activity is contained in the Standard Operating Procedure regarding energy saving during RS Gas Turbines. With the existence of an optimization program for operating patterns by turning off the lube oil cooler fan, it is hoped that it will be able to reduce power, with the target of reducing electric power consumption by 40,000 KWh per year. This program can save 165,454.34 kWh of power in 2020, or the equivalent of 595.64 GJ, and in 2021 it can save 101,468.40 kWh of energy, or the equivalent of 365.29 GJ.
联合循环电厂(CCPP) Block 1-2 PT. PLN Indonesia Power Priok的润滑油冷却器风扇被用作热交换器，以降低通过系统的润滑剂的温度，使其能够以较低的温度返回系统。由于PLN负载调节器的要求，CCPP Block 1-2经常经历启停单元，因此即使在停机(RS)期间润滑油温度较低，润滑油冷却器风扇也经常继续运行。润滑油冷却器风扇优化程序是一项活动，在反向停机装置期间关闭一个风扇，当润滑油温度低于42℃时，由操作员手动关闭所有风扇，然后记录为文件。这项活动包含在关于RS燃气轮机节能的标准操作程序中。通过关闭润滑油冷却器风扇的运行模式优化程序的存在，希望能够降低功率，目标是每年减少40,000千瓦时的电力消耗。该方案2020年可节电165,454.34 kWh，折合595.64 GJ, 2021年可节电101,468.40 kWh，折合365.29 GJ。

Saat ini, sampah menjadi salah satu dilema di setiap negara, baik di negara berkembang maupun di negara maju. Pengangkutan sampah dari Tempat Pembuangan Sementara menuju Tempat Pembuangan Akhir dengan truk sampah yang lambat dapat menyebabkan terjadinya penumpukan sampah. Untuk itu diperlukan suatu sistem yang dapat memberikan notifikasi kepada petugas untuk segera mendatangi tempat sampah yang sudah penuh dan mengangkut sampah tersebut ke Tempat Pembuangan Akhir. Penelitian ini bertujuan untuk merancang dan membangun sebuah sistem monitoring ketinggian sampah yang diterapkan pada wadah sampah di sebuah Alat Pemilah Sampah Otomatis. Sistem monitoring ini dipasang pada wadah sampah logam, organik, dan anorganik yang terdiri dari tiga buah sensor ultrasonik HC-SR04 yang terpasang pada masing- masing wadah sampah tersebut. Sistem ini dikendalikan oleh mikrokontroler yang dapat terhubung dengan internet yaitu NodeMCU ESP8266. Pemantauan ketinggian tempat sampah dapat dilakukan dimana saja dengan menggunakan perangkat yang sudah terinstal aplikasi Blynk. Dari hasil dari pengujian diketahui bahwa sistem dapat mengukur ketinggian sampah secara real-time mulai dari jarak 0 sampai dengan 25 cm. Sistem monitoring juga dapat mengirim notifikasi ketika wadah sampah sudah penuh sampai dengan pengujian sejauh 1 km.

The Seven Step multilevel inverter has 3 H – Bridge switching circuits which are designed from transistor and IGBT semiconductor circuits. The performance of the switches is regulated by the ignition unit which consists of pulses of frequency with a certain ignition angle. This pulse pulse determines the output voltage form of the H-Bridge multilevel inverter circuit. The output voltage form is a square pulse. There are seven step output voltage levels that are close to a sinusoidal shape, but still contain high levels of harmonics. This large Total Harmonic Distortion (THD) can be overcome by increasing the number of levels or steps in the output voltage by adding an H-Bridge strand to the next level. The modeling of this 7 step multilevel inverter circuit is designed using Matlab Simulink Tools.

Load Breaking Switch (LBS) is an asset that has an important role in the distribution system with the role of disconnecting and connecting the flow of electrical power from a 20 kV distribution system, LBS can also be used as a section when adding or reducing feeder loads and is often used as a maneuvering point between Feeder. To optimize the function and operation of the Motorized LBS, it is necessary to integrate the SCADA system so that it can be operated remotely. In this integration process, one of the important components needed is the Remote Terminal Unit (RTU) which functions as a device that provides information about the equipment and carries out orders (teleinformation), but to achieve this we are constrained by the very expensive price of the RTU. For this reason, an alternative remote terminal unit is needed as a substitute for the RTU which represents the function of the RTU on the scada system itself. By installing alternative RTUs, SAIDI decreased by 17.74 % and recovery time by 2.99 %.

Poverty is a condition where a person or household has insufficient income to meet the minimum living needs. BPS states that 40% of Indonesians are in the lowest economy. One of the measures to tackle poverty by the government is the application of electricity subsidies. The government in collaboration with PT. PLN to control poverty has an electricity subsidy program by providing electricity subsidy assistance funds to underprivileged communities. The purpose of the subsidy is to achieve electricity supply and help poor customers and those who have not been contacted by PT. PLN so that they can participate in enjoying electrical energy. However, there are still obstacles where there are many procedures so that it takes a long time to make decisions, because it must be seen from several criteria. One of the methods used to overcome the many criteria of FMADM is TOPSIS to complete 10 alternatives including: Job, Income, Dependents, Vehicle Assets, Home Ownership, Building Area, Drinking Water Source, Electrical Power Range, type of floor, and type of house wall. The results of the study obtained accurate results, namely from 20 submissions, only 11 residents were automatically acceded without having to wait a long time in the decision to grant electricity subsidies. And for 9 residents, they were given recommendations to be acc, 1 citizen was given a recommendation not to be acc
