Abstract

Lighting is one of the most important requirements of a building. This is because inadequate lighting of a space can affect the health and comfort of activities in that space. In addition to less important lighting, room temperature adjustments, room temperature adjustments have a significant impact on comfort during activities in the room. This magazine describes the lighting and room temperature control design of the CilacapState Polytechnic Welder Shop. The method used in this study is a quantitative method. This method calculates the required lighting and room temperature control and compares it with the standards. 2 rooms increase the number of light points and 3 rooms change the type of lamp with a higher lumen. There are 8 rooms that are recommended to use air conditioners with SNI 91714189. According to the SNI, the number of air conditioners and the capacity of air conditioners adjusts to the size of the room.

Abstract

Renewable energy sources in Indonesia have been widely used, one of which is solar energy, for various needs, one of which is for solar power generation by using solar cells as the medium. In generating electricity, solar cells are very dependent on the intensity of the sun so as to produce currents and voltages that are not constant. Because of this, a monitoring system was created to monitor the current and voltage in a solar cell module to determine current and voltage conditions. In this study, the monitoring system used wireless data transmission via the XBee S2C module installed on the Arduino Mega 2560 and Arduino UNO. The INA 219 sensor is mounted on a solar cell module along with a relay module connected to the Arduino Mega 2560 and the XBee S2C module. The test results show that wireless data transmission cannot be used indoors at a distance of more than 20 meters. The INA 219 sensor as a reader for DC current and voltage parameters has an error rate of 0.49% to 0.75% for voltage and for DC current readings it has an error rate of 1.85%. The results of current and voltage readings are displayed on a LabVIEW interface in real-time and can be accessed via a web browser using a local network. Relay control carried out through LabVIEW has a delay time of 6.08 seconds. Logging data can be stored in .xls files and data displayed on a web browser has a delay of one to two seconds.

Abstract

In general, the kWh meter is installed in a distribution substation that supplies electrical energy to the building. The weakness of ordinary kWh meters cannot provide real information on electricity consumption. Measuring and recording the use of electrical energy still requires human power. By utilizing an internet network based on the Internet of Things (IoT) concept, this research aims to design and manufacture a digital kWh meter to monitor and control the use of electrical energy in buildings in real-time on a website. Using the website and the MYSQL-PHPMyAdmin Database as data storage. The PZEM-004T sensor is used to measure the electrical energy used, then it is processed on the Wemos D1 Mini microcontroller. From the test results that have been carried out, the digital Kwh meter has succeeded in monitoring and controlling the use of electrical energy through the website in real-time. Percentage average error value: voltage: 0.44% - 0.49%, current: 0.36%, cos phi leading: 39%, cos phi lagging: 1%, power: 0.93% - 2.68%, kWh: 16.3%, frequency: 0 %.

Abstract

Indonesia has a large solar energy potential, with an average radiation of 4.5-4.8 kWh/m² every day. Politeknik Negeri Cilacap (PNC) can take advantage of this opportunity to develop a Solar Power Plant. This study examines the possibility of building an on-grid rooftop solar power plant in the Department of Electrical and Mechatronics Engineering. This study uses Homer to simulate the solar power plant design. The parameters discussed are total energy production (kWh/year), renewable fraction, net present cost/NPC (Rp) which is all costs used in construction, both in installation and operation of the solar power plant and Cost of energy/COE (Rp/kWh) which is the cost incurred to produce electrical energy per 1 kWh. The results of the study include an average solar energy at PNC of 4.66 kWh/m²/day. Based on Homer's simulation results, the total energy generated by the solar power plant is 149,056 kWh/year, with 68,599 kWh/year from photovoltaic and 80,457 kWh/year from the PLN grid. The renewable fraction is 44.8%. The NPC is Rp 1,880,000,000, and the CoE is Rp 1,000/kWh.

Abstract

Pada sistem otomasi, Programmable Logic Controller (PLC) adalah perangkat berbasis mikrokontroler yang dirancang khusus untuk mengendalikan berbagai jenis proses. Program dalam PLC disimpan dalam memori dan dibuat menggunakan perangkat lunak CX Programmer, dengan diagram wiring dalam bentuk ladder. Penelitian ini berfokus pada otomasi proses pengisian minyak dan penutupan botol menggunakan PLC Omron CP1L. Sistem menggunakan empat input dengan alamat 000, 001, 002, dan 004, serta tiga output dengan alamat 100.00, 100.02, dan 100.05. Fungsi dari ketiga output ini adalah mengendalikan M1 sebagai penggerak konveyor, pompa DC 12 V, dan M2. Penelitian ini menerapkan sistem otomatisasi yang beroperasi secara real-time saat proses berlangsung. Sistem ini dimulai dari tombol start, yang menggerakkan botol secara berurutan, dan akan berhenti ketika mendeteksi sensor proximity yang mengirim sinyal untuk memulai proses berikutnya. Sistem akan berhenti ketika tombol stop ditekan. Hasil pengukuran menunjukkan kecepatan motor saat membawa beban 150 ml hingga 350 ml adalah 20-27 rpm, dengan rata-rata tegangan output sebesar 11 V dan arus output sebesar 2-3 A. Total daya yang dibutuhkan mencapai 108,558 W. Jarak pembacaan sensor pertama adalah 8 cm, dan sensor kedua adalah 21 cm. Terdapat pula penyesuaian waktu pengisian minyak dari 150 ml hingga 350 ml, dengan durasi antara 50 hingga 160 detik.

Abstract

Widarapayung Wetan Village was designated as an innovation village by the Cilacap Regency Innovation Village Determination which is located in Binangun District, Cilacap Regency. The main potential of Widarapayung Wetan Village is in the tourism sector, such as Widarapayung Beach and the pioneering tourist village. The facilities that have been built and already exist in this pilot tourism village are an art performance stage, pavilion, gazebo, gamelan instruments, plantation land, and rice fields. One of the pioneering developments of tourist villages is the development of educational tourism. This community service activity applies appropriate technology by developing water pump technology for irrigating rice fields using solar energy. Apart from irrigating rice fields, this solar-powered water pump technology is also used for educational tourism at the Widarapayung Wetan tourism village pilot, especially in the field of utilizing new and renewable energy. The stages of work carried out included surveying the installation site, designing and manufacturing a solar water pump system, system installation at the installation site, operational trials of pumps, and operational training and pump maintenance. The result of this activity is a solar water pump system for irrigating rice fields with a capacity of 30 liters/minute.

Abstract

To avoid the occurrence of currents, jumps or electric sparks between electrical conductors, then isolation is used. Insulating oil is one of the insulating materials used in transformers that function to isolate and cool electrical equipment. The properties of transformer insulating oil change when it contains pollutants that enter the oil, in which causes faster failure. Besides the change of temperature will also affect the strength of the insulating oil. The results showed that the percentage contribution of the effect of temperature and salt content on the breakdown voltage was 36.4% with a temperature increase of 10C followed by an increase in the breakdown voltage of 0.044 times and each increase in the salt content was followed by a decrease in the breakdown voltage of 0.292 times.
