A dye sensitized solar cell (DSSC) is a low-cost solar cell with attractive features. DSCC contains of photoelectrode, dye, electrolyte, and counter electrode with photoelectrochemical system. The aim of this research is to determine the percent efficiency produced by DSSC from the Mahkota Dewa extract. This was carried out in various stages, namely sample preparation and extraction, DSSC assembly, TiO2 characterization using Scanning Electron Microscopy (SEM), and testing its current and voltage. The results showed that the maximum wavelength of the Mahkota Dewa extract dye test using a UV-Vis spectrophotometer was 554 nm with an absorbance of 0.163, which was believed to be the wavelength of flavonoid and anthocyanin compounds. Based on the characterization results, surface morphology was spherical and agglomerated. However, after being soaked in the dye, the surface morphology of the TiO2 layer did not appear spherical on the surface that was expected to have been covered by the dye. The measurement using sunlight sources showed that the maximum current and voltage of DSSC with a concentration of 30% w/v was 21.8x10-4A and 58.86 V with an efficiency of 22.43x10-3 %. In addition, there was a 0.482% decrease in DSSC efficiency based on the storage time which lasted for a period of 6 days.

AbstractPersyaratan Umum Instalasi Listrik (PUIL) are requirements that must be met in electrical installations. The application of the PUIL standard in electrical installations is very important in order to avoid unwanted things due to errors in electrical installations such as fire. West Aceh State Community Academy, which is a vocational college, really needs electricity to operate practicum equipment. If the electrical installation at the Aceh Barat State Community Academy does not meet PUIL standards, it is very vulnerable that the practicum equipment will be damaged quickly and even a fire occurs because the practicum equipment requires a fairly large amount of electrical power. The purpose of this study was to analyze the suitability of the Kuat Hantar Arus (KHA) in the electrical installation conductors of the West Aceh State Community College based on the 2011 PUIL standards. The research method used was the method of literature study and field observation. The results showed that in general the KHA conducting electrical installations at the West Aceh State Community Academy which was divided into 10 lines was very good where 2 lines were in accordance with the standards and 8 lines were above the 2011 PUIL standards. Keywords:PUIL 2011; Electrical Installation; Strong Conducting Current..__________________________ AbstrakPersyaratan Umum Instalasi Listrik (PUIL) merupakan persyaratan yang harus dipenuhi pada instalasi listrik. Penerapan standar PUIL pada instalasi listrik sangat penting dimana untuk menghindari hal-hal yang tidak diinginkan yang dikarenakan kesalahan pada instalasi listrik seperti kebakaran. Akademi Komunitas Negeri Aceh Barat yang merupakan perguruan tinggi vokasi sangat membutuhkan listrik untuk mengoperasikan alat-alat praktikum. Apabila instalasi listrik di Akademi Komunitas Negeri Aceh Barat tidak memenuhi standar PUIL maka sangat rentan alat-alat praktikum tersebut akan cepat rusak dan bahkan terjadi kebakaran karena alat-alat praktikum tersebut membutuhkan daya listrik yang lumayan besar. Tujuan penelitian ini adalah menganalisis kesesuaian Kuat Hantar Arus (KHA) pada penghantar instalasi listrik Akademi Komunitas Negeri Aceh Barat berdasarkan standar PUIL 2011. Metode penelitian yang digunakan adalah metode studi pustaka dan observasi lapangan. Hasil penelitian menunjukkan bahwa secara umum KHA penghantar instalasi listrik Akademi Komunitas Negeri Aceh Barat yang dibagi 10 jalur sudah sangat baik dimana 2 jalur sudah sesuai standar dan 8 jalur berada di atas standar PUIL 2011. Kabel yang terpasang diatas standar pada beberapa jalur dianggap sangat baik dikarenakan apabila suatu saat nanti dilakukan penambahan beban maka masih mampu dilayani oleh penghantar tersebut.

AbstractThe quality of electrical energy is a crucial requirement for the Akademi Komunitas Negeri (AKN) Aceh Barat. Electrical outages negatively impact performance, as equipment cannot be utilized during these times. A generator set is a machine that produces electrical energy and serves as a backup when the electrical supply from PLN is interrupted. Currently, AKN Aceh Barat has a generator set with a capacity of 7,800 watts, which is insufficient to meet the academy's power demands. The average monthly energy consumption from April to September 2024 is 5,199.83 kWh. To overcome the lack of power from the generator set, priority loads have been designated based on the importance of different rooms that facilitate essential services, ensuring that teaching and learning activities can proceed effectively. The generator's backup energy primarily supports a load of 6,290 watts, reaching an operational loading percentage of 81%. The electrical energy distribution from the generator to these priority rooms is managed through a new installation known as the Automatic Transfer Switch (ATS) panel, which activates automatically when the electrical supply from PLN is disrupted.Keywords:Power; Electrical; Distribution; Generator; EfficiencyAbstrakKualitas energi listrik menjadi kebutuhan utama bagi Akademi Komunitas Negeri Aceh Barat, pemadaman energi listrik berdampak buruk terhadap kinerja yang disebabkan peralatan tidak dapat digunakan. Generator set adalah mesin generator yang mampu menghasilkan energi listrik yang digunakan sebagai energi cadangan bila suplai energi listrik dari PLN terputus. pada AKN Aceh Barat generator set yang tersedia memiliki daya sebesar 7.800 watt dan tidak mampu memenuhi kebutuhan daya yang diperlukan oleh AKN Aceh Barat, rata-rata pemakaian beban AKN Aceh Barat dari bulan april sampai bulan September tahun 2024 mencapai 5.199,83 kWh per bulanya. Untuk mengatasi kekurangan daya dari generator set sebagai energi cadangan maka dipilih beban prioritas berdasarkan ruang prioritas yang berfungsi untuk pelayanan sehingga kegiatan belajar mengajar berjalan dengan baik. besar beban prioritas yang distribusi oleh daya generator sebagai energi cadangan sebesar 6.290 watt dengan persentase pembebanan mencapai 81%. Distribusi energi listrik dari genset ke ruang prioritas sebagai energi cadangan terhubung dengan instalasi baru yaitu panel ATS yang hidup secara automatis bila suplai energi listrik dari PLN terputus.Kata kunci:Daya; Distribusi; Listrik; Generator; Efisiensi

Traffic Steering is an additional technique applied to network traffic especially when filtering, modification, or optimization is required. Network operators usually use traffic steering to expand the value of VAS or value-added service (value-added service that refers to additional services (content) based on existing telecommunication networks). This technique is applied so that the use of traffic from a link can be directed according to the client's needs and further maximize the functional use of the link itself. In general, the implementation of traffic steering is built based on three concepts, namely: NAT (Network Address Translation), Firewall RAW, and IP Routes. In this Traffic Steering implementation, the DSTNAT chain feature on the NAT firewall is used to direct access with the destination that has been set to a specific web server.
