Abstract

The greater the power losses, the higher the loss costs for the transformer. These losses can occur due to load, no-load, and load imbalance factors. This study aims to obtain the cost of losses incurred due to these three factors for ten years (2023-2033). The estimated cost of losses due to unbalance is obtained from the calculation of power losses in the neutral of the transformer, the cost of no-load losses is obtained from the losses of the iron core in the transformer, In contrast the cost of load losses is influenced by the development of the load and the interest rate for each year. As a result, the greatest power losses occur under unbalanced conditions with an average load for ten years of 88.68%, followed by no-load conditions of 11.10% and 0.21% load. The total power losses for ten years amounted to Rp. 3,029,196,416.64.

Abstract

Crackers are one of the food commodities favored by Indonesian people. Most of the cracker business actors are MSMEs. The main problem faced by many MSMEs is the lack of business knowledge, so they are often inferior to manufacturing businesses. The same thing was experienced by MSME crackers in Krembung District, Sidoarjo which was managed by Mr. Abdul Ghofur. In this service activity, the University of Surabaya Informatics Engineering has an assistance program through technology, to expand the market share that can be reached and help MSME financial management. The programs carried out are the development of an online market place information system that is integrated with the financial system. The activity begins with program socialization and problem analysis. After that, it is followed by application development, training, mentoring, as well as observation and evaluation. Finally, reflection is carried out for the continuation of further activities. The duration of this community service activity is eight months, including one month of assistance to ensure that MSME personnel are able to use the system properly. During the mentoring process, business processes at MSMEs can run more smoothly, where sales transactions are more centralized in the system, stock records are better, and owners can get financial information more accurately and easily. Therefore, it can be concluded that this community service activity went well and helped Mr. Abdul Ghofur's MSME business processes. Service activities will be developed by providing supplies in the form of digital marketing so that MSMEs can reach new customers to access this application.

Abstract

Ruang publik merupakan elemen penting dalam suatu perumahan, berfungsi sebagai sarana interaksi sosial guna meningkatkan kualitas hubungan antar warga. Perumahan diperkotaan, khususnya di kampung kota seringkali tumbuh tak terencana dan berkembang menjadi permukiman padat. Fenomena tersebut terjadi pada perumahan di RW 03 Kelurahan Petamburan, Kecamatan Tanah Abang, Jakarta Pusat. Program pengabdian masyarakat ini bertujuan untuk membantu masyarakat dalam menangani permasalahan kepadatan hunian dan pengelolaan spasial komunal. Salah satunya dengan memberikan pemahaman, pengetahuan, memberikan contoh ruang publik yang memenuhi standar kesehatan dan kenyamanan, serta perilaku komunal yang bertanggung jawab dalam menjaga dan mengelola sarana - prasarana secara partisipatif melalui mekanisme self-organization. Kegiatan PKM ini dilakukan dengan metode pendekatan PAR atau participatory action research, dalam bentuk konsultasi dan pendampingan pada desain fisik ruang yang berfokus di balai RW 03. Ruang luar komunal tersebut ada yang terbentuk secara spontan, sehingga kualitas fisik ruangnya sangat minim. Kegiatan PKM ini diharapkan dapat meningkatkan pemahaman dan kemampuan masyarakat setempat dalam mengorganisasikan diri untuk berpartisipasi pada penyelenggaraan lingkungan yang layak huni, terutama di ruang luar komunalnya. Hasil yang diharapkan dari program PKM: (1) identifikasi harapan dan masalah dalam rencana perancangan penyempurnaan fisik ruang luar komunal; (2) usulan program dari komunitas; (3) poster perancangan penyempurnaan fisik ruang luar komunal, publikasi jurnal, dan Hak Cipta.

Abstract

The use of electric motors in industry often experiences damage caused by several things, including high starting current surges, overload or full load, loss of one phase in the electric motor, and other causes of damage to the 3-phase motor. The main problem that occurred in this research was damage caused by high starting currents, where in the case study many 3-phase motors were used to drive factory machines. The use of 3-phase motors to drive factory machines is often damaged by unstable currents in the machines. This is because the time and workers for monitoring are very minimal and the materials for repairing machines are inadequate. In this way, the solution for repairing a 3-phase motor is to replace and rewind the damaged motor so that it can be used again. This research aims to find a solution on how to reduce high starting currents in 3-phase motors by utilizing the influence of replacing damaged induction motor components as well as repair methods used in starting when rewinding 3-phase motors. The research results from the groove distance with a wire size of 0.90 mm showed that the groove distance of 9, 9, 8 was 29.3, and at a distance of 10, 10, 10 it had a current of 31 A with no-load testing and recommended groove distances of 10, 10, 10. Next, testing wire sizes of 0.75 mm and 0.90 mm with distances of 10, 10, 10, and 9, 9, 8 without load obtained 26.1 A and 27.4 A while 0.90 mm was 30, 7 A and 28, 1 A. The load was 43.5 A and 43.9 A, while 0.90 mm was 51.3 A and 49.3 A. From the test results, the largest current decrease was at a distance of 10, 10, 10 with a wire size of 0.75 mm. Keyword - 3 Phase Induction Motor, Groove Spacing, Starting, Wire Size.

Abstract

The voltage generated by the generator will always change due to the fluctuating load. The output voltage must be kept constant within the desired value to ensure the supply of generator output power to meet the load requirements, a device called an AVR (Automatic Voltage Regulator) is needed. AVR aims to regulate the amount of excitation current supplied to the generator and the amount of excitation current is directly proportional to the amount of voltage generated by the generator. This study aims to analyze the performance of the AVR in maintaining the stability of the generator output voltage and power. Monitoring the performance of the AVR installed on the generator is carried out for 31 days. The results of monitoring and analysis after the generator installed AVR, it can be seen that the output voltage is in stability with a variation in the value between 11.59 kV to 11.8 kV while the generator output power is also still in stability with a variation in values ??between 38.1 MW to 38.3 MW.
