Abstract

Humanitarian organizations that support social communities by providing work opportunities for employees. In actuality, a website is required to serve as a channel for contacting new contributors and publicizing the organization. In order to create websites for humanitarian organizations using the task-centered system design methodology, research was done based on these issues. Identification, requirements, design as a scenario, and walkthrough evaluation are the four stages of this process. The PACT framework is used to identify users and necessary tasks during the identification phase. The tasks that are actually required are then chosen at the requirements stage. The task-based design is then completed using the Figma program during the design as scenario stage. The workflow and usability of the website, which was developed utilizing cognitive walkthrough and SUS, are also evaluated at this point. Based on the findings of the assessment, it can be said that cognitive walkthrough testing can be used to assess the components of an interface that are easy to learn, effective, and efficient, and that SUS can be used to assess the usability of the design outcomes. Based on the findings of the cognitive testing, a learnability and effectiveness score of 95% with the predicate "very good" and an average efficiency value of 0.1 goals/second with the predicate "very fast" were obtained. The SUS test then yielded an acceptable predicate and a SUS rating of 83

Abstract

Load balancing is one of the things that must be considered by reducing the value of voltage drops or power losses that occur in distribution channels. It is necessary to know the characteristics of the load in an area or area with a balanced supply so that each phase is burdened evenly. Calculating the voltage drop on the distribution network conductors, the voltage drop on the KBN09 Slawi feeder was calculated. What will be calculated here is from the line to the transformer furthest from the GI, namely from the three-phase 20 kV main line, single-phase branching. The results of power calculations from GI Kebasen Tegal show differences between R, S and T phases with three 20 kV phases in pre-balance and post-balance conditions. As written, the value for R wire is 82661.52 W, for S 52613 W, while for the T phase the value is 60127.06 W. Meanwhile, the calculation of power losses from GI Kebasen Tegal shows differences between the R, S and T phases with 1 phase voltage in the conditions before balance and after balanced. On the 3-phase line for the R wire, the power loss decreases from 34,198 W to 17,0425 W, for S it increases from 11,540 W to 19,077 W, while for the T phase the value remains 15,274 W.

Abstract

The Department of Education, Youth and Sports is a government agency that operates in the formal and non-formal education service sector as well as in managing education governance in schools. The Department of Education, Youth and Sports has a structural field, one of which is the SUPEG field "General and Personnel Sub-Section", where it deals with a lot of issues related to general and personnel, one of which is incoming and outgoing letters. However, there are obstacles and problems faced, namely that incoming and outgoing letters often have double numbering, some letters cannot be found, the archive process is still manual and there are many other problems. With the existence of this incoming and outgoing mail archive website, it is hoped that it will be useful and can solve this problem at SUPEG in the future. The website was designed using native PHP language and several collaboration languages, namely JavaScript, CSS and others, for the database itself using Xampp. The final result of this research is the production of an Archives Website for Incoming and Outgoing Mail. who can provide information and solve problems that occur in SUPEG "General and Personnel Sub-Section" especially in the correspondence section both within the agency and from outside.

Abstract

The Gondoriyo 1-phase network has a network length of 3.2 km supplied by a 1-phase network that is charged in phase S on BSB 1. The extent of the service area makes the load on phase S jump high. The measurement results obtained by the load current during peak load reached a total of 62A. While the load current of the repeater at the time of peak load is phase R of 32A, phase S of 98A, and phase T of 44A. With such conditions, it is necessary to expand the medium voltage distribution network in the Gondoriyo area with the aim of balancing the load on the BSB 1 extension. To facilitate load sharing in the expansion of the Gondoriyo area, the ETAP powerstaion 7.5.0 simulation program is used. which consists of 1 phase simulation before expansion and 3 phase simulation after expansion. From the results of this engineering shrinkage simulation, the total engineering shrinkage value in the 1-phase network before the expansion was 6480 kW, after the network expansion, the total engineering shrinkage changed to 2510.4 kW. With the simulation that has been made, it is expected to produce a load sharing plan that will make it easier for PT PLN (Persero) Rayon Boja to share the load on the network after the expansion.

Abstract

Sistem distribusi merupakan bagian dari sistem tenaga listrik yang berfungsi menyalurkan energi listrik ke konsumen. Penggunaan energi listrik akan terus berkembang dan hal ini mengharuskan adanya perkembangan jaringan distribusi, sehingga kerja dari sistem proteksi membutuhkan keandalan dalam menjaga peralatan penyaluran dari gangguan diantaranya gangguan hubung singkat. Oleh karena itu untuk meminimalisir gangguan tersebut diperlukan sistem proteksi yang memenuhi persyaratan sensitifitas, keandalan, selektifitas dan kecepatan, yang semuanya tergantung pada ketepatan dalam setting peralatan proteksinya. Salah satu peralatan proteksi yang digunakan adalah relai arus lebih (OCR) dan relai hubung tanah (GFR),yaitu relai yang berfungsi mengistruksikan PMT untuk membuka sehingga gangguan pada jaringan yang terganggu dapat dipisahkan dari sistem pendistribusian tenaga listrik. Pada penulisan penelitian ini akan dibahas evaluasi antara setting OCR dan GFR BWN 02 dan BWN 09 pada Gardu Induk Bawen. Hasil perbandingan setting koordinasi proteksi perhitungan dengan simulasi, menunjukkan bahwa setting koordinasi proteksi perhitungan dapat bekerja dengan baik dibanding dengan simulasi yang terpasang di Gardu Induk Bawen. Hasil perhitungan dari setting OCR pada sisi incoming di dapat nilai TMS = 0,151, sedangkan setting OCR pada sisi outgoing didapat nilai TMS = 0,127. Penyetelan GFR pada sisi incoming di dapat nilai TMS = 0,345, sedangkan setting GFR pada sisi outgoing didapat nilai TMS = 0,172. Koordinasi antar relay pada perhitungan sudah sesuai dengan standart IEC 60255 dengan granding time 0,3-0,5 detik.

Abstract

Energi fosil adalah energi yang paling banyak digunakan, namun ketersediaan bahan bakar fosil semakin menipis. Energi terbarukan dapat digunakan sebagai salah satu pemenuhan energi. Panel surya adalah salah satu energi terbarukan yang bekerja dengan mengubah energi matahari menjadi energi listrik. Pemanfaatan panel surya biasanya dihubungkan langsung dengan beban tanpa konverter pada tegangan rendah. Digunakan boost converter untuk menaikkan tegangan DC. Tegangan keluaran panel surya tergantung pada iradiasi dan beban yang disuplai panel surya. Untuk menjamin tegangan keluaran panel surya konstan, diperlukan umpan balik tegangan pada konverter DC-DC. Pada Penelitian ini dirancang boost converter mengunakan umpan balik tegangan pada panel surya. Tahapan perancangan diawali menghitung komponen boost converter, verifikasi menggunakan software PSIM dan implementasi perangkat keras. Boost converter telah berhasil dibuat dan mampu menghasilkan tegangan keluaran lebih besar sebesar 21,9 – 41,8 volt. Penguatan boost converter dari duty cycle 0%-80% adalah 0,96 – 5,56. Dari pengujian menggunakan umpan balik tegangan variasi iradiasi, beban, iradiasi dari matahari, dan partial shading, tegangan keluaran konverter mampu dijaga konstan 24 volt dengan error rata-rata 0,36%, 0,35%, 0,95%, dan 0,11%. Efisiensi rata-rata boost converter tanpa umpan balik tegangan 85,37% dan dengan umpan balik tegangan 90,26%.
