Abstract

Easy access to distributed generation (DG) technology is promoting the utilization of single-phase DGs for residential purposes. Surplus energy generated by household DGs can be shared or sold to other communities through existing networks. However, the interconnection of single-phase DGs from residential generators to the distribution network requires careful handling to secure the reliability and quality of the electric power system. This paper focuses on the optimal placement of single-phase multi-type DGs on unbalanced distribution systems that are connected to nonlinear loads. The objective of this study is to minimize the power losses and voltage unbalances in the distribution networks. To verify the efficacy of this method in reducing voltage unbalances and harmonics, an optimization approach is also presented using three-phase DG. Optimal placement of DG is performed on a modified Kaliasin distribution system using an adaptive real coded genetic algorithm (ARC-GA). Simulation results demonstrate that the installation of single-phase DGs is highly effective in reducing power losses and voltage unbalances in the distribution networks.

Abstract

Electricity is one of basic human needs. However, PLN's ability to meet customer demands is hampered by its limitations. On the other hand, the sunny geographical advantage of Makassar city can be utilized as a new renewable and environmentally friendly energy source in a smart home. Smart house is a family residence that is able to synergize electricity usage based on the habits of its residents with the help of smart technology so that comfort, safety and efficiency of using electrical energy are obtained. The utilization of solar cell hybrid power – battery – PLN can be implemented in addition to meeting the needs of electricity load in the smart home, it can also contribute excess energy to fulfill off-grid building load.  Monte Carlo Simulation (MCS) is carried out at the beginning of data processing by randomly generating 24-hour models of solar irradiance and smart home load requirements along with weather conditions. PLN not only takes over fulfilling the needs of the smart home load when there is less and or no sunlight and minimum battery capacity conditions, but also it will charge the battery capacity up to 100% every midnight. On average, the daily load requirement for a smart home is almost half the energy produced by PVs, which are 12,439 kW and 24,509 kW respectively. Furthermore, the smart home hybrid power is capable of producing 8,946 MW of excess energy in a year to serve the off-grid building load needs.

Abstract

Penggunaan daya listrik pada gedung Kantor Bupati Kabupaten Halmahera Barat semakin hari semakin bertambah sesuai dengan kebutuhan dan perkembangan Kabupaten Halmahera Barat di masa akan datang, otomatis penambahan daya sangat diperlukan. Untuk memperoleh daya listrik terpasang yang efisien, oleh karena itu perlu dilakukan observasi dan perhitungan daya yang digunakan sesuai dengan ilmu kelistrikan.Konsumen komersial atau perkantoran rata-rata memiliki standar faktor kebutuhan sebesar  70% - 90% dan faktor beban 25% - 30% untuk mendapatkan penggunaan daya listrik yang efisien. Faktor kebutuhan adalah perbandingan antara kebutuhan maksimum (beban puncak) terhadap total daya tersambung.Total penggunaan daya maksimum 197,4 kVA dengan standar faktor kebutuhan sebesar 1,88. Total luas ruangan ber-AC 9.361 m2, dengan mengkomsumsi energi listrik selama satu bulan totalnya 36.135 kWh/bulan, jika di bandingkan dengan standar IKE maka nilainya sangat efisien, berbeda dengan perhitungan IKE untuk ruangan tidak ber-AC yang memiliki total luas ruangan 875 m2 dan mengkomsumsi energi selama satu bulan 2,484 kWh/bulan, jika di bandingkan dengan standar IKE untuk ruangan tidak ber-AC maka nilai IKEnya masuk kriteria ruangan yang boros atau sangat boros mengkomsumsi energi listrik.Kata kunci: Daya listrik terpasang, factor beban, faktor kebutuhan, perbandingan intensitas  komsumsi energi (IKE).

Abstract

Teknologi jaringan Generasi ke-5 (5G) menjadi fenomena yang baru di Sulawesi Selatan dimana akan terjadinya migrasi teknologi jaringan Generasi ke-4 (4G) ke 5G. Menyusul semakin meningkatnya penetrasi pengguna internet, maka wajar jika teknologi 5G perlu segera diterapkan. Penelitian ini menggunakan metode observasi berupa studi literature dan wawancara. Data yang diperoleh dianalisis menggunakan metode Strength-Weakness-Opportunities-Threat (SWOT). Hasil analisis migrasi 4G ke 5G berdasarkan perubahan arsitekturnya adalah Serving Gateway (SGW), Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Evolved-Universal Terresterial Radio Access Network (E-UTRAN), dan Next Generation-Radio Access Network (NG-RAN). Standar pengimplementasian teknologi jaringan 5G berdasarkan rekomendasi International Telecommunication Union (ITU) melalui program International Mobile Telecommunication (IMT)-2020. Pada kurun waktu 2018 sampai 2021, jumlah pengguna internet di Sulawesi Selatan meningkat sebesar 67,6%. Sementara itu selang waktu tiga tahun jumlah desa/kelurahan yang  dapat dilayani Base Transceiver Station (BTS) berteknologi 4G bertambah 335 wilayah. Hal tersebut menjadi salah satu peluang yang dimiliki Sulawesi Selatan untuk mengimplementasikan jaringan 5G. Ditambah lagi infrastruktur yang cukup baik menjadi salah satu kekuatan karena tersedianya 94% BTS 4G dari keseluruhan BTS di tahun 2021. Hanya saja perlu memaksimalkan teknologi Device to Device (D2D). 5th Generation (5G) network technology is a new phenomenon in South Sulawesi where there will be 4G to 5G technology migration. Following the increasing penetration of internet users, the technology needs to be implemented immediately. This study used observation method in the form of literature studies and interviews. The obtained data were analyzed using Strength-Weakness-Opportunity-Threat (SWOT) method. The analysis results of  4G to 5G migration based on architecture evolution are Serving Gateway (SGW), Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Evolved-Universal Terresterial Radio Access Network (E-UTRAN), and Next Generation-Radio Access Network (NG-RAN). The standards required for the 5G network technology implementation are based on the recommendation of International Telecommunication Union (ITU) through International Mobile Telecommunication (IMT)-2020 program. During 2018 to 2021, the number of internet users in South Sulawesi increased by  67,6%. Meanwhile, the number of villages/wards served by BTS with 4G technology expanded by 335 area for three years. This is one of the opportunities for South Sulawesi implementing 5G network. Futhermore, sufficiently good infrastructure is as one of the strengths due to the availability of 94% of 4G BTS from all BTS in 2021. However, it needs to maximize Device to Device (D2D) technology.

Abstract

Koperasi Baba Farm Torano menghadapi kendala dalam pemantauan kestabilan pH dan konsentrasi nutrisi pada sistem hidroponik, karena proses pemantauan yang masih dilakukan secara manual, lambat, dan sering menghasilkan data yang tidak konsisten. Untuk mengatasi masalah tersebut, tim PKM mengembangkan dan menerapkan sistem monitoring berbasis Internet of Things (IoT) menggunakan sensor pH dan TDS yang terintegrasi dengan mikrokontroler. Sistem ini memungkinkan pemantauan kondisi larutan secara real time melalui aplikasi pesan singkat (telegram) maupun diakses melalui website. Pelaksanaan program meliputi sosialisasi, pelatihan penggunaan perangkat, penerapan teknologi pada instalasi hidroponik, serta pendampingan dan evaluasi. Hasil kegiatan menunjukkan peningkatan signifikan pada keterampilan teknologi mitra berdasarkan perbandingan nilai pre-test dan post-test, serta peningkatan produktivitas panen sebesar 15–20% setelah penerapan IoT. Secara keseluruhan, program PKM ini berhasil meningkatkan efisiensi kerja, kualitas produksi hidroponik, dan kapasitas teknologi Koperasi Baba Farm Torano dalam mendukung kemandirian pangan lokal.
