Abstract

Program listrik prabayar merupakan terobosan PT. PLN yang dikeluarkan tahun 2008. Salah satu alasan selain untuk meningkatkan pelayanan, dibuatnya program listrik prabayar ini diantaranya adalah kejadian salah baca meter, tagihan yang tidak menentu, tunggakan rekening dan salah pemutusan. Listrik Prabayar atau Token adalah terobosan dari PLN dalam menjawab permasalahan yang kerap terjadi dalam sistem pencatatan meteran. Sistem token ini selain meminimalisasi aksi-aksi penyimpangan, juga mampu mengajak masyarakat lebih bijak dalam menggunakan listrik. Akan tetapi, pada kenyataannya banyak masyarakat yang belum mengetahui perhitungan listrik prabayar yang selama ini mereka gunakan. Oleh karena itu perlu diberikan sosialisasi perhitungan listrik prabayar dan simulasi perhitungannya pada masyarakat.

Abstract

Road is a vital public facility that connects one region to another region. Hence, the existence of public street lighting is a key to supports people’s activities at night. But not all roads are equipped with public street lighting. For example, the village roads in Sukarame Village, Sajira sub-district, Lebak regency, Banten. This village is fully electrified but the supply for public street lighting is still limited. Therefore, it is neccesary to install public street lighting in the form of solar lamps as an effective alternative for street lighting and public facilities. Solar lamp is chosen because it doesn’t need power supply and the village’s geographical is very potential for utilizing solar lamps. Solar lamps installed in 3 strategic points, which are village road in front of local kindergarten, village road in front of public field, and mosque’s terrace. Besides solar lamp installation, this research also focused in economic analysis of this program. The analysis was done by comparing total cost needed for conventional public street lighting using bulbs that connect to grid with total cost needed for public street lighting using solar lamps. Despite solar lamp’s price is more expensive, for the long-term usage, public street lighting using solar lamps is more economically profitable compared to conventional public street lighting with the cost difference of Rp 636,582.80 per lamppost for 3 years usage period.

Abstract

As the rising of electricity demand, electricity load profile characterization (ELPC) is the integral aspect in planning, operating system, and distribution network development. The approach in the existing ELPC is still relatively macro in nature and does not involve other aspects outside the electricity variable, so the results tend to be biased for areas experiencing rapid land use changes. Therefore, this paper proposes an ELPC approach based on micro-spatial. Microspatial analysis is done by dividing area in the form of the smallest grids involving various electrical, demographic, geographic and socio-economic variables, which are then grouped using adaptive clustering based on fuzzy C-means (FCM). The adaptive clustering algorithm is proven to be able to determine the degree of membership of each grid data against each cluster with the ability to determine the number of clusters automatically according to the attribute data provided. The ELPC results which consist of 5 clusters are then analyzed using descriptive statistic, plotted, and mapped to obtain more accurate and realistic load characteristics in accordance with the pattern and geographical conditions of the region, so that the results can be used as a reference in load forecasting, network development, and distributed generation (DG) integration.

Abstract

Listrik merupakan kebutuhan yang sangat vital untuk menunjang operasional manusia. Saat ini, rasio elektrofikasi di Indonesia sudah mencapai 98,93 %. Untuk mencapai rasio elektrofikasi sampai 100% tentunya ada tantangan tersendiri, selain sebaran konsumen yang tidak merata seperti di daerah terpencil juga biaya yang dibutuhkan untuk membangun suatu jaringan yang besar serta ketersediaan suplai listrik dari pembangkit. Keterbatasan suplai listrik ini juga dialami oleh kampung Gadog di Desa Sukamahi, Kab. Cianjur yang berada di daerah perbukitan dan kondisi ketersediaan suplai listrik di desa tersebut belum 24 jam. Untuk mengakomodir permasalahan akan kebutuhan listrik ini, maka tim membangun Pembangkit Listrik Tenaga Surya (PLTS) rooftop off grid yang terkoneksi dengan instalasi jaringan arus searah (DC). Karna instalasi berupa jaringan DC (DC House) maka untuk saat ini pembebanan sebatas 5 titik penerangan masing – masing 5 Watt dan pompa air DC dengan kapasitas 180 Watt. Agar listrik yang dihasilkan PLTS tidak hanya dinikmati oleh satu rumah warga, maka tim juga menyediakan saluran pengisian daya listrik untuk mengecas portable power yang dimiliki warga.

Abstract

Kampung Gadog Desa Sukamahi merupakan sebuah kampung yang terletak di Cianjur Jawa Barat. Topologi Kampung Gadog dikelilingi oleh persawahan sehingga mayoritas masyarakat berprofesi sebagai petani. Pendapatan masyarakat yang rendah mengakibatkan kondisi masyarakat kurang sejahtera. Untuk membantu masyarakat meningkatkan perekonomiannya dan melihat potensi air yang melimpah serta menerapkan IPTEK di kampung Gadog, maka tim akan membangun kolam budidaya ikan lele. Yang perlu diperhatikan untuk budidaya ikan lele adalah waktu pemberian pakan tepat waktu, sedangkan masyarakat menghabiskan waktu seharian jika bercocok tanam di sawah / di ladang karena posisi yang jauh. Untuk memfasilitasi hal tersebut maka pemberian pakan akan menggunakan automatic fish feeder yang sudah dilengkapi dengan photovoltaic di bagian atas alat.. Sedangkan penerapan IPTEK menggunakan pompa air DC berbasis energi surya, dimana pompa air ini akan digunakan untuk proses pengairan kolam. Untuk fish feeder dalam pemberian pakan dapat di setting sesuai dengan kebutuhan, dimana dalam hal ini settingan waktu yang dibuat adalah dalam setiap 5 jam sekali. Kolam yang digunakan adalah kolam konvensional dengan ukuran panjang x lebar x tinggi adalah 3m x 2m x1m, dengan jumlah 4 unit kolam yang terbagi menjadi 1 kolam untuk pembibitan, 1 kolam untuk pertumbuhan dan 2 kolam lainnya untuk kolam panen. Dan untuk pompa air yang digunakan untuk menguras dan atau mengisi kembali air ke kolam digunakan pompa Air DC dengan kapasitas output pompa sebesar 180 Watt ,12 Volt.

Abstract

Load demand forecasting is crucial in energy supply planning due to economic progress and territorial expansion, where land utilization transforms dynamically. An accurate sectoral load prediction can preclude the loss of beneficial opportunities arising from excessive load demand or excessive investment at a low-growth juncture. However, the particular area in this sectoral approach is still relatively large, rendering it incapable of precisely projecting load at minor points (micro-spatial). This study has proposed a micro-spatial load prediction strategy that categorizes identified areas into smaller grids or districts. This procedure includes clustering similar sites together for improved accuracy. K-Means is one of the partitional clustering approaches, a clustering algorithm utilizing object-based centroid-based partitioning approaches. The algorithm determines a cluster's centroid or centre as the average point for the cluster. This technique is advantageous as it can process extensive data efficiently and is appropriate for circular data. This technique can divide the data into multiple partitions, ensuring that each object belongs to precisely one cluster. Subsequently, mathematical modelling is used to predict the load of each cluster, which can then be utilized to more accurately evaluate the positions and sizes of prospective substations, transmission, and distribution facilities.

Abstract

The Timor system is one of the large systems in the East Nusa Tenggara region. Based on the general plan for electricity supply for 2021-2030, there is a plan to interconnect a 2x11 MW wind power plant. The addition of wind power plants will pose a considerable threat to the system due to the intermittency nature of renewable energy plants. Therefore, a comprehensive grid impact study is needed to convince network managers that adding wind farms will not cause disruptions to the system either locally or in general and is expected to strengthen the electricity system. The power flow simulation results, installing a 2x11 MW wind farm on the Timor system can improve voltage quality and reduce losses on both 70 and 150 kV systems. For transient stability, the frequency value on the Timor system still meets the grid code requirements. In addition, the simulation results of the intermittency impact of the wind power plant output show that the Timor system is still in a stable condition. The stability of the rotor angle of the existing power plant when the transient stability simulation is carried out shows that it is still in a balanced condition.
