Kemajuan komunikasi yang berkembang sesuai dengan kemajuan zaman. terdapat keinginan manusia untuk dapat meningkatkan pengiriman suara ditambah gambar yang bergerak yang dikenal dengan Televisi, Tujuan dari penelitian ini untuk mengetahui besar kuat sinyal yang di terima pada lokasi tertentu dalam daerah layanan TVRI stasiun Makassar berdasarkan kuat medan hasil pengukuran dan hasil perhitungan. Penelitian dilakukan dengan cara mengambil data pengukuran yang dilakukan oleh TVRI pada daerah-daerah layanannya dengan menggunakan alat ukur (Field Strength Meter ML 512 A / Merk Anritzu). Daerah pengukurannya yaitu daerah Gowa dan Takalar. Hasil analisis diketahui kuat sinyal yang sampai ke daerah Gowa masih baik, sedangkan pada daerah Takalar kuat sinyal cukup baik dimana noise sudah ada. Dari hasil perhitungan kuat medan, kuat sinyal yang sampai ke penerima sudah baik yaitu di atas 40 dBµ,V. Adanya perbedaan antara hasil pengukuran dan perhitungan disebabkan oleh beberapa hal seperti, pembacaan yang kurang tepat

Analisis Faktor Penurunan Gangguan Saluran Udara Tegangan Menengah (SUTM) Pada Penyulang Parangbanoa

The reliability of the electric power system is one of the most important things to pay attention to in order to maintain the performance of the three main pillars of PT. PLN (Persero). The problem that often occurs in the distribution sector is interference with feeders. The purpose of this study was to determine the causes of trip feeder disturbances in parangbanoa feeders at PT. PLN (Persero) ULP Kalebajeng. The problem that often occurs in the distribution sector is feeder disturbance. Based on the results of the ArcGIS (Geometry Informindo System) output, the potential causes of trip disruption in the parangbanua feeders are trees and plants that affect SUTM, animals on the network, damaged JTM components, broken insulators, and less tight connections causing hot temperatures. Maintenance activities carried out are divided into integrated maintenance. saving obtained is 7,418 kWh / week, and the gain obtained can reach Rp. 10,882,206, - / week, while the benefits are a reduction in the number of interruption of feeder trips

PEMANFAATAN AIR LAUT SEBAGAI SUMBER CADANGAN ENERGI LISTRIK

The development of science and technology is growing rapidly, as well as the development of knowledge about alternative energy. This study aims to analyze the design of the circuit form so as to produce electric current and to determine the operating flow of a series of seawater energy generating devices as a source of electrical energy reserves. The research was carried out by taking measurement data carried out by the Electrical Engineering laboratory. From the results of the measurement experiment the use of sea water explains that at one liter produces a voltage of 0.86 V, when using two liters produces a voltage of 1.85 V, when using three liters produces a voltage of 2.57 V. From the results of the research It was carried out that the voltage contained in 1 container of seawater was obtained 0.68 V, with the information of the lamp being off, and for 4 containers of sea water obtained a voltage of 3.87 V with a description of the lamp of life. This marine energy is used not only to turn on LED lights, but is used to power electricity in a narrow area or even in large areas. If this sea water energy can be developed in Indonesia, then the Indonesian state can save energy, because most of Indonesia's territory is water / sea. Energy sources derived from fossils at any time will soon be depleted. From the results of research conducted, it can be concluded that this sea water can be used as a source of renewable and environmentally friendly energy reserves

Penanganan, Pengolahah, dan Pengawasan Pangan (Tanaman, Ikan dan Ternak)

Adriani A. 2022. Food handling, processing and control (plants, fish and livestock). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang  27 Oktober 2022. pp. 18-26. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The purpose of handling, processing and controlling foodstuffs is to ensure their availability for the people of Indonesia. These foodstuffs must be in a healthy, safe and sustainable condition. However, in the development of food supply from plants, livestock and fish, there are global challenges. The global challenges of food supply are climate change which is uncertain, arable land is getting limited, clean water is getting limited and the population is increasing. Of course this is a challenge in the provision of food in the future. One of them is by increasing productivity, sustainability and quality. On the other hand, food handlers must pay attention to quality and quantity to consumers. Physical, chemical and biological treatment of food ingredients needs serious attention from raw materials, processing, transportation and storage to produce quality food. In accordance with the 5.0 industrial revolution, the availability of quality food is a priority so that the quality of human life increases, is safe and comfortable
