Abstract

We still often hear in the media that there are fire accidents caused by leakage currents/short circuit currents and accidents due to being hit/touched by electric currents which cause injuries and even fatalities. The Indonesian government has determined that in carrying out electrical installation activities, it must comply with the General Electrical Installation Requirements (PUIL). One of the efforts to assist the government in socializing PUIL to the public in electrical installations, especially on a household (Domestic) scale and because there has never been a PUIL-standard electrical installation socialization or restructuring activity in that area, a community service activity (PkM) is planned to be located in Jl. Parigi Village, RT. 04 RW. 06, Sukamulya, Rumpin, Bogor, West Java 16350. Based on the survey that has been conducted, it was found that along the roads in the area, street lighting installations are generally not standard PUIL 2011 and have had a long service life and many have died. then a restructuring of the electrical installation must be carried out to avoid accidents due to electric shock. The method used in this PkM is to work with the local community in restructuring public street lighting installations. This is done so that people can be given knowledge about how to install electricity and immediately put it into practice. The tools and materials used to check and restructure electrical installations include: multimeters, tespen, miniature circuit breakers, lamps, cables, electrical insulation, and other supporting tools. The result of this PkM activity is that electrical installations on several power poles along roads in the area are feasible for use and in accordance with PUIL 2011.

Abstract

The performance of solar panels greatly determines the electrical energy production of a solar power generation system. The decrease in performance has an impact on efficiency, output power, output voltage and current. Currently, at Universitas Pamulang a solar photovoltaic system (PV) is installed with a capacity of 2.56 kWp since 2018. However, no performance test and analysis have been conducted to determine its level of efficiency and reliability. This paper presents an experimental method used for performance testing of a 320 W mono-crystalline solar panel, measuring from 08.00 AM to 4.00 PM, using the solar survey 200R to measure solar irradiation, ambient and cell temperature. A digital multimeter CD800a was used to measure Voc and a PV200 tester used to measure voltage and current output. The results revealed that at an ambient temperature of 38°C and cell temperature 50.9°C, the intensity of solar radiation was 702.7 W/m2 and output voltage of 42.9 V with a performance of 78.37% and an efficiency of 27.73% was due to an increase cell temperature. Low-efficiency values with high cell temperatures indicate that this system requires an external solar panel cooling system.

Abstract

Matahari merupakan salah satu bintang raksasa pada alam semesta. Matahari ini menyediakan berbagai macam energi tidak terbatas di dalamnya. Dengan perkembangan teknologi, energi matahari dapat dimanfaatkan sebagai alternatif sumber energi listrik yang banyak dibutuhkan oleh umat manusia, yang artinya matahari menghasilkan energi listrik dengan menggunakan teknologi panel tenaga surya. Panel surya sebagai alat yang mampu mengubah energi cahaya matahari menjadi energi listrik. Potensi energi surya di Indonesia sangat besar yakni sekitar 4.8 kWh/m2 atau setara dengan 112.000 GWp, namun yang sudah dimanfaatkan baru sekitar 10 MWp. Saat ini pemerintah telah mengeluarkan roadmap pemanfaatan energi surya yang menargetkan kapasitas PLTS terpasang hingga tahun 2025 adalah sebesar 0.87 GW atau sekitar 50 MWp/tahun. Jumlah ini merupakan gambaran potensi pasar yang cukup besar dalam pengembangan energi surya di masa datang. Akan tetapi penerapan panel surya saat ini masih terbatas pada bidang industri dan perumahan menengah ke atas, hal ini dikarenakan investasi awal yang cukup mahal sehingga penerapan teknologi panel surya masih terbatas. Oleh karena itu perlu dilakukan suatu terobosan dalam upaya peningkatan minat masyarakat akan penerapan panel surya tersebut. SMK merupakan instansi pendidikan khusus kejuruan yang sangat memerlukan pengembangan ilmu pengetahuan dan teknologi dalam sistem pembelajarannya. Dengan diberikan informasi melalui pengenalan teknologi panel surya diharapkan siswa memiliki skil tambahan sehingga mampu bersaing di dunia kerja setelah lulus nanti. Dampak lain dari keahlian tambahan ini siswa dapat langsung dirasakan oleh masyarakat. Pengenalan sistem panel surya ini juga diharapkan agar masyarakat dapat memiliki pemahaman akan pentingnya penerapan sumber energi panel surya sebagai sumber energi bersih dan ramah lingkungan. Bentuk pengenalan teknologi panel surya ini berupa trainer panel surya 50 Wp yang saat ini di wilayah Tangerang Raya khususnya SMKN 4 Tangerang belum ada trainer panel surya.

Abstract

A solar cell is a semiconductor element that can convert solar energy into electrical energy on the basis of the photovoltaic effect. The solar module is a collection of several solar cells. The power generated by solar cells is influenced by the level of solar radiation and ambient air temperature, the lower the solar radiation, the lower the power generated. So that the power generated by solar cells is always optimal, it is necessary to adjust the position of the sun's light to vary the intensity of solar radiation. The system used for such regulation is called a solar tracker system. This research discusses the performance of solar trackers with solar cells as sensors. The solar tracker captures direct light, the voltage is processed by Arduino and the servo motor acts as a drive to adjust the direction of the solar cell to a direction perpendicular to the sun's light. The input of the system is the position of the sunlight and the output is the direction of the solar cell in degrees. This sun tracking system can show a stable response to the movement of solar cells in accordance with the perpendicular position of sunlight so that the power generated by solar cells can be more optimal. This research succeeded in functioning solar cells as solar tracking sensors.

Abstract

Sistem plumbing gedung bertingkat merupakan salah satu bagian terpenting dalam menyediakan air bersih. Air bersih pertama kali ditampung pada ground water tank, kemudian dikirim ke roof tank menggunakan pompa melalui pipa discharge. Ketika pompa motor induksi 3 fase ON dan OFF, terjadi suara dentuman dan getaran yang keras pada pipa discharge pompa air bersih. Hal ini sebagai permasalahan yang membuat para tenant tidak nyaman dan dapat merusak pipa discharge karena terjadinya benturan akibat perbedaan kecepatan aliran fluida pada komponen pipa discharge atau disebut water hammer. Perlu diperbaiki kecepatan aliran fluidanya agar konstan. Mengubah metode sistem kontrol motor dari pengasutan StarDelta menjadi pengasutan variable speed drive (VSD). Tujuan merubah akselerasi dan deselerasi motor sehingga suara dentuman dan getaran pipa discharge hilang dan tidak terjadi lonjakan (surge) fluida pada pipa discharge. Hasil pengujian pengasutan StarDelta menimbulkan suara dentuman dan getaran baik saat motor ON maupun OFF, sementara pada pengasutan VSD tidak terjadi getaran. Suara dentuman dan getaran akibat sistem pengasutan StarDelta dapat dihilangkan dengan mengubah metode sistem kendali menjadi sistem pengasutan VSD.

Abstract

A mechanical jack is one of the tools that is needed for every vehicle owner, especially in car workshops. Smartphone is a modern communication tool and the most widely used today. Some individuals or institution also have to take advantage of technological developments to make work more effective, efficient, and safer. For example, in operating a mechanical jack, although it looks simple, it requires time and energy to operate it. Therefore, a prototype of a mechanical jack controller was made by maximizing the Smartphone as an interface that is connected to the NodeMCU ESP8266 Microcontroller via the internet network which can later be developed in its actual form. The method used is to program NodeMCU for DC motors, current sensors, load cells, with the aim that the jack can be controlled remotely and the current on the DC motor and the load on the jack can be monitored via a smartphone. The results obtained from the study are, the jack can increase and decrease the maximum load of 5kg, with a current when rising is 0.31A, and the average time to rise is 42 seconds. With the effectiveness of the working distance between the jack and the smartphone can be controlled remotely.

Abstract

Photovoltaic (PV) temperature is an important parameter that can influence PV performance. The increase in PV temperature can cause a drop in PV output voltage, which indicates that the PV does not operate optimally. In this paper, a design of an integrated cooling system based on fuzzy logic to control the PV temperature is presented. This, in effect, will potentially ensure that the PV performance is at its maximum condition. In this work, the temperature of the PV is kept constant by attaching a cooling system that carries water inside it. The constant temperature of the cooling system is carried out through a radiator and thermoelectric with electronic control. The experiments are carried out using two 320-watt PV systems; one with the cooling mechanism and the latter without the cooling system as a control. Several important data such as temperature, voltage, current, and radiation measurement in each PV were collected for three days from 10:00 to 17:00 with an interval of 10 minutes for each measurement. The results of the integrated cooling system measurement showed an increase in PV power generation and efficiency of 1.32% compared to the control PV unit. From the results of the study, it can be concluded that the fuzzy logic-controlled cooling system contributed to the increase in PV performance.
