Abstract

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

Abstract

Geothermal Power Center is a power plant with renewable energy. Basically, PLTP is a power plant whose raw materials come from the bowels of the earth in the form of hot steam. This steam is obtained from several wells which are then channeled through a transmission pipe system to the PLTP unit. after arriving at the PLTP the steam is controlled and regulated, and the pressure is then channeled to the steam turbine which rotates the electric generator. This research discusses the response of the electronic governor when the system frequency drops which affects the work of the Kamojang PLTP unit 4 equipment. From various methods applied it is evident that when the system frequency drops all PLTP equipment is disrupted, especially the condenser level where the pressure increases from 780 mmH2O to 1023 mmH20. this can cause the turbine to trip so that it needs to be responded to properly by maneuvers on the operating side so that the generator is able to survive under conditions of system frequency disturbances down.

Abstract

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.

Abstract

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.

Abstract

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%.

Abstract

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%.

Abstract

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.
