Abstract

The lighting system is one of the aspects of assessing the function of the building. The building lighting system is included in the health aspect of the building. To achieve proper function, the building lighting system must meet the illumination value of each room according to the type of utilization in accordance with SNI 6197:2011, SNI 6197:2011, SNI 03-2396-2001, dan SNI 03-6575-2001. This study aims to analyze the lighting system in the Gedung Kuliah Bersama at the Politeknik Negeri Cilacap. This study uses a quantitative method by comparing the amount of light intensity based on field measurements, calculation results, and the SNI 6197:2011 standard. Based on the results of observations, data processing, and measurements, it was found that there were still some rooms in the Gedung Kuliah Bersama that did not meet SNI. Rooms that have fulfilled SNI include classrooms, library rooms, language laboratories, lecturer transit rooms, multipurpose rooms, terrace, and warehouses. It is necessary to carry out maintenance and repair of lamps for rooms that do not meet SNI. Maintenance and repair of lighting systems are carried out by replacing, adding, and/or repositioning lamps.

Abstract

Land requirements are one of the obstacles to developing solar power plants . One solution is to utilize the surface of the reservoir for the construction of floating solar power plants. Excessive heat from sunlight received by photovolataics reduces the effectiveness of floating solar power plants output. Excessive heat in photovoltaics can be reduced by cooling methods. In this research, a photovoltaic cooling system using water was developed. A water pump is installed to channel reservoir water to the photovoltaic surface. The cooling system uses two methods, namely the sensor and timer method. In the sensor method, a sensor is installed on the solar power plants to detect the photovoltaic surface temperature. If the temperature detected by the sensor exceeds the photovoltaic effectiveness limit, the water pump is started. In the timer method, the pump is run based on a preset time. Based on the test results, the cooling system is able to increase the photovoltaic voltage output. The average value of the timer mode cooled photovoltaic voltage is 3.79% higher compared to the photovoltaic voltage without cooling and the average value of the sensor mode cooled photovoltaic voltage is 1.02% higher than the photovoltaic voltage without cooling.

Abstract

Mesin pemipil jagung menggunakan motor listrik sebagai penggerak utamanya dan panel surya yang terhubung dengan baterai sebagai sumber energi utamanya dan PLN sebagai sumber energi cadangan. Dengan adanya mesin ini diharapkan mampu meringankan beban petani jagung dalam proses pemipilan yang tadinya masih menggunakan tenaga manual bahkan menggunakan mesin besar dengan biaya yang relatif mahal. Tujuan perencanaan mesin pemipil jagung tenaga panel surya yaitu untuk mengetahui cara membangun alat pemipil jagung menggunakan teknologi panel surya dan untuk mengetahui berapa kapasitas produksi yang dihasilkan mesin pemipil jagung dalam waktu 1 menit. Berdasarkan hasil pengujian sebanyak 5 kali.Nilai rata-rata kapasitas mesin dalam memipil jagung sebesar 760,6 gram/menit.
