Abstract

Public street lighting (PJU) is an infrastructure that supports community activities at night, as lighting for pedestrians and vehicle users, so as to improve driving safety and comfort, improve environmental security and prevent crime. The existence of PJUs that are not controlled, such as forgetting to turn them off until noon is often the cause of the high consumption of electrical energy. This is often ignored by the public and is considered normal, even though when viewed from the total national energy consumption it has extraordinary consequences. Saving electricity consumption is a solution to the problems faced by the community, with the manufacture and installation of an automatic PJU light control system. The purpose of this PJU lamp automatic control system is to make it easier to operate PJU lamps so as to reduce electrical energy consumption. The stages of implementation in Community Service are a solution to problems by making direct observations to the location to find out the components needed, designing control systems, procuring tools and materials, assembling control panels, installing and testing automatic control systems, providing education to the community. of the importance of controlling the consumption of electrical energy by not neglecting the safety and security of electrical hazards by applying standardization in the use of electrical equipment. The expected results in this Community Service, apart from providing safety and comfort, increasing environmental security and preventing crime as road users, can also provide public understanding and concern for energy saving, safety and security in using electricity.

Abstract

Perkembangan komunikasi bergerak sudah sangat maju teknologi. Tujuan perkembangan jaringan komunikasi bergerak adalah menyediakan standar yang dapat memenuhi aplikasi-aplikasi nirkabel yang luas variasinya, tidak hanya mampu menyediakan jenis layanan dasar seperti suara (voice) dan pesan (messaging) saja melainkan telah diperluas hingga mampu menyediakan jenis layanan multimedia dan high multimedia. Salah satu karakter layanan multimedia dan high multimedia adalah sifat keasimetrisan dari sisi trafiknya, sehingga kebutuhan data rate pada arah downlink berbeda dengan kebutuhan data rate pada arah uplink. Hal ini dapat menyebabkan ketidakefisienan penggunaan bandwitdh apabila diimplementasikan dengan menggunakan sistem FDD, untuk hal tersebut maka UMTS juga mengeluarkan standard TDD dimana pada sistem ini alokasi time slot antara uplink dan downlink dapat diatur sehingga sistem dapat mencapai kondisi optimal. Pengalokasian time slot antara uplink dan downlink yang optimal disimulasikan dengan metode alokasi time slot seragam (uniform allocation) dan metode alokasi time slot tak-seragam (non-uniform allocation). Masing-masing formulasi kedua metode alokasi time slot tersebut diselesaikan dengan metode optimasi simpleks. Dari hasil simulasi tersebut terlihat bahwa metode uniform allocation sesuai untuk jenis trafik simetris dan komposisi trafik antar sel yang seragam, sedangkan metode non-uniform allocation sesuai untuk jenis trafik asimetris dengan tingkat keasimetrisan yang tinggi. Pada kondisi rasio interferensi yang tinggi maka metode non-uniform memiliki tingkat ketahanan kapasitas yang lebih baik dibandingkan metode uniform.

Abstract

Telah dilakukan pengembangan sistem pengontrolan berat menggunakan PID berbasis Arduino dan Paralax Data Acqusition. Pengontrolan berat pada benda cair ini berguna dalam proses di industri. Loadcell (Strain gauge) akan membaca besar nilai dari berat benda cair tersebut. Loadcell dirancang dengan menggunakan Arduino UNO R3 yang didalamnya terdapat mikrokontroler ATMEGA 328P menggunakan komunikasi data Integrated Inter Circuit (I2C) sebagai penghubung terhadap LCD sebagai display dan menggunakan gear pump sebagai alat penambah ataupun pengurang dalam pengontrolan berat pada benda cair ini. Untuk menampilkan hasil pengukuran dari loadcell digunakan software Paralax Data Acqusition yang akan menampilkan grafik serta tabel data pengukuran. Data hasil pengukuran menunjukan bahwa pompa akan bekerja mengikuti set point yang telah ditentukan dan menyesuaikan berdasarkan kondisi pembacaan berat. Berdasarkan hasil pengujian ini maka sistem  dapat digunakan menjadi sistem pengontrolan berat pada benda cair.

Abstract

The role of solar power plants can be an alternative energy as a substitute for electricity from PLN. In addition, solar power plants are also environmentally friendly power plants because of the energy obtained from the sun. The purpose of this study is to analyze the load needs of solar power plants with the number of installed canteens, analyze the capacity of the area to determine the potential capacity of the installed VP, and analyze the capacity and type of power efficiency in the installed area. In this study, the PV tested was monocrystalline with a capacity of 485 Wp, with a total PV of 108 units. In this test, the area that will be used in the construction of the Unpam Viktor Rooftop Solar Power Plant has a width of ± 9 meters and a length of ± 70 meters, or an area of ± 630 m². The area of this array is a large rooftop that can be used as a place-to-place solar PV, which has a width of ± 9 meters and a length of ± 70 meters or an area of ± 630 m², with dimensions of the PV array which are 2252 x 1048 x 35 mm (88.7 x 41.3 x 1.38 in). The total of 108 PVs produced a power of 52.5 kWp. The total electricity demand of the canteen per day is 81,900 kWh.

Abstract

Instalasi kelistrikan tidak tertata dengan baik beresiko kebakaran akibat korsleting dan menyebabkan biaya listrik mahal. Masalah ini berdampak terhadap keamanan dan keberlangsungan operasional. PkM ini bertujuan untuk menambah sumber energi alternatif bersumber photovoltaik dilengkapi pewaktu pada penerangan lapangan dalam meningkatkan kenyamanan kegiatan santri. Diterapkan metode analisis kebutuhan, pemilihan bahan standar, pemasangan instalasi, pengujian dan evaluasi dengan melibatkan santri. Hasil menunjukkan peningkatan signifikan dalam aspek tata kelola instalasi dan mengurangi risiko kebakaran akibat korsleting. Partisipasi santri menjadi faktor kunci keberhasilan yang menciptakan rasa memiliki dan kesadaran akan pentingnya keamanan instalasi listrik. Selanjutnya diperlukan pemeliharaan rutin instalasi dan edukasi berkala. Kegiatan ini menunjukkan kontribusi nyata dalam pemberdayaan masyarakat melalui pendekatan inovatif dan berkelanjutan.

Abstract

This activity is designed to provide a deep technical understanding to the people of Ciasmara Village regarding the routine maintenance of the Micro Hydro Power Plant, including cleaning the intake, inspecting the turbine, and maintaining the electrical system so that the plant can operate more reliably and efficiently. So that residents are able to handle daily maintenance and prevent damage that can interfere with operational continuity. This activity consists of several stages, including surveys, formulation of training manuals and modules, socialization and training, establishment of institutions and independent funding systems, and upstream environmental conservation education. The results of this activity are expected to make a real contribution to the development of a more targeted socialization strategy, increase community participation in technical maintenance, and support independent and sustainable plant management. In addition, this activity can also be considered for local governments, non-governmental organizations, and donor institutions in designing renewable energy-based community empowerment programs. With this activity, there will be a collective awareness from the community of the importance of maintaining and caring for the energy infrastructure that has been built, not only as a source of electricity, but also as a long-term socio-economic asset.
