Abstract

An energy audit needs to be carried out to calculate energy consumption in buildings. This activity is a form of energy management which aims to meet national energy needs in accordance with long-term energy management policies, including Law no. 30 of 2007, concerning energy. This research uses data on the use of electrical energy at the Tiara Residence boarding house. The results of the energy audit serve as a reference for increasing profits from the boarding house business by saving on monthly electricity usage costs based on the amount of electricity consumption paid. This research was carried out by calculating the energy consumption intensity (IKE) value with influencing variables including energy consumption (kWh) per square meter (m2) per month. Based on the results obtained, the monthly power consumption is 1049 kWh-1231 kWh at a cost of Rp. 1,576,836-Rp. 1,852,473, then the IKE value is calculated and it is known that the efficiency level of energy use is in the efficient category in February, March, July, August, September and October, while in January, April, May, June it is categorized as very efficient. Apart from that, there are opportunities to save from installed electrical equipment by applying special behavior to the equipment.

Abstract

This research aims to evaluate the biomass energy potential in North Sumatra using the Long-range Energy Alternatives Planning (LEAP) system. North Sumatra, a region rich in agricultural and forestry resources, presents significant opportunities for biomass energy development. The LEAP model, a widely used tool for energy policy analysis and climate change mitigation assessment, was employed to simulate and analyze various scenarios of biomass energy utilization in the region. Key biomass resources in North Sumatra, such as palm oil residues, rice husks, and wood waste, were identified and quantified. The study involved the collection of data on biomass availability, current usage patterns, and technological options for biomass energy conversion. By integrating these data into the LEAP model, different scenarios were developed to explore the potential contributions of biomass energy to the regional energy mix and greenhouse gas (GHG) emissions reduction. The analysis results show that in 2028, the significant potential for new and renewable energy in North Sumatra includes water energy, wind energy and biomass energy. The potential biomass energy produced is 27.0 MW.

Abstract

Provinsi Sumatera Utara menghadapi tantangan yang signifikan dalam pengelolaan sampah akibat peningkatan populasi dan aktivitas ekonomi. Sebagian besar sampah yang dihasilkan adalah sampah organik yang memiliki potensi besar untuk diubah menjadi sumber energi alternatif melalui teknologi biogas. Penelitian ini menganalisis potensi sampah organik di Sumatera Utara sebagai sumber energi listrik alternatif, dengan fokus pada proses konversi sampah menjadi biogas melalui fermentasi anaerobik. Hasil analisis menunjukkan bahwa pemanfaatan biogas dari sampah organik dapat menghasilkan energi listrik. Potensi energi listrik yang dihasilkan dari pengkonversian sampah menjadi biogas pada tahun 2020 sebesar 25.14 MW, pada tahun 2021 sebesar 30.25 MW, pada tahun 2022 sebesar 65.74 MW, dan pada tahun 2023 sebesar 70.86 MW.

Abstract

Beban penerangan, beban air conditioner (AC) dan peralatan listrik portabel memainkan peranan penting dalam menentukan kebutuhan daya listrik pada sebuah gedung. Penentuan kebutuhan daya listrik yang tepat dapat meningkatkan efisiensi penggunaan energi listrik sehingga dapat menurunkan biaya tagihan listrik. Selain itu juga dapat menanggulangi resiko kebakaran akibat listrik. Penelitian ini memiliki tujuan untuk mengevaluasi kebutuhan daya listrik pada Gedung Distributor Kertas PT X Medan sesuai dengan standar kelistrikan yang berlaku. Evaluasi dilakukan dengan cara membandingkan kebutuhan daya listrik hasil perhitungan sesuai dengan standar PUIL 2011 terhadap daya listrik yang terpasang pada gedung. Berdasarkan hasil perhitungan diperoleh total kebutuhan daya listrik untuk Gedung Distributor Kertas PT X Medan sebesar 22.290 Watt dengan perincian kebutuhan daya listrik untuk penerangan sebesar 2.250 Watt dan kebutuhan listrik untuk AC sebesar 20.040Watt. Berdasarkan hasil observasi, daya listrik terpasang pada gedung sebesar 23.000 VA. Dengan demikian, daya terpasang Gedung Distributor Kertas PT X Medan perlu dinaikkan hingga 26.000VA untuk menanggulangi dampak faktor daya dan pemakaian peralatan listrik portabel

Abstract

Pada perkembangan telekomunikasi yang semakin berkembang pesat kebutuhan akan energi listrik juga semakin tinggi, untuk itu perlu digunakan energi alternatif untuk menutupi kebutuhan energi. Energi alternatif dapat memanfaatkan energi yang terdapat di bumi salah satunya yaitu gelombang elektromagnetik bebas dengan menggunakan sistem RF (Radio Frequency) energy harvesting. Salah satu komponen penting pada sistem RF (Radio Frequency) energy harvesting adalah antena. Pada penelitian ini dirancang antena mikrostrip array patch segiempat frekuensi 2100 MHz yang terdiri dari atas 4 susunan. Dari hasil pengukuran antena didapat nilai VSWR dan return loss yang terbaik sebesar 1,07 dan -29,25 dB pada frekuensi 2170 MHz. Tegangan keluaran dari antena mikrostrip yang diimplementasikan pada sistem RF energy harvesting adalah sebesar 17 mV untuk pengukuran daerah kota Medan, yaitu di Laboratorium Sistem Komunikasi Radio, 29 mV untuk pengukuran daerah kota Medan di Jalan Abdul Hakim dan 33 mV untuk pengukuran di Plaza Medan Fair. Dari implementasi yang telah dilakukan dapat diambil kesimpulan tegangan yang dipanen di dalam ruangan lebih kecil dibandingkan di luar ruangan.

Abstract

Three-phase transformers are integral components of modern electrical power systems, serving as the backbone of energy transmission and distribution networks. Their primary purpose is to step up or step-down voltage levels efficiently, enabling the transfer of electrical power over long distances with minimal losses. Due to their widespread use in industrial, commercial, and residential applications, understanding the operational characteristics of three-phase transformers is crucial for improving energy efficiency, ensuring reliability, and optimizing performance. The analysis of transformer characteristics, such as efficiency, voltage regulation, power losses, and behavior under varying load conditions. This research aims to analyze the characteristics of three-phase transformers using MATLAB. The results of the analysis obtained in the study of the characteristics of 3-phase transformers produce an active power (P) of 6183.42 W, a reactive power (Q) of 3832.14 VAR, an apparent power (S) of 7274.61 VA and a transformer efficiency of 97.75% with a time of 0.02 s and produces losses in copper of 81.65 W which forms electromagnetic field radiation where the radiation pattern of the electric field (E field) and the magnetic field (H field) is in the form of a polar graph.
