Abstract

Kegiatan pengabdian ini bertujuan meningkatkan manajemen kelompok usaha mikro tersebut. Kegiatan ini dilakukan dengan mengadakan alat pencetak produk plastik yaitu alat Blow Molding Plastik, dan kegiatan- kegiatan pelatihan manajemen dan pembukuan serta pelatihan pengoperasian dan perawatan alat. Dengan alat blow molding plastik ini diharapkan bisa meningkatkan nilai jual sampah plastik dari kelompok usaha mikro tersebut. Target dan luaran yang diharapkan pada kegiatan Ipteks bagi Masyarakat ini adalah: (1). Terciptanya satu alat blow molding plastik, dimana alat blow molding plastik tersebut dapat menghasilkan produk plastik baru dengan bahan baku sampah plastik hasil dari penampungan sampah plastik tersebut, (2). Kelompok usaha mikro yang telah terlatih dalam mengoperasikan dan merawat alat blow molding plastik, dan (3). Kelompok usaha mikro yang telah terlatih tentang manajemen usaha dan pembukuan. Metode pelaksanaan kegiatan ini dilakukan dengan pelatihan manajemen dan pembukuan, perancangan dan pembuatan alat blow molding plastik yang meliputi observasi lapang, perancangan alat blow molding plastik, fabrikasi dan perakitan, pengujian alat blow molding plastik, pelatihan pengoperasian dan perawatan alat, monitoring dan evaluasi. Hasil dari kegiatan program pengabdian masyarakat ini, diperoleh hasil yang cukup baik, yaitu dihasilkannya sebuah alat blow molding plastik yang diaplikasikan pada kelompok usaha mikro tersebut untuk meningkatkan nilai jual produk dan pendapatan kelompok usaha mikro, kelompok usaha mikro yang mendapatkan peningkatan kemampuan dalam hal manajemen usaha, pembukuan, pengoperasian dan perawatan alat blow molding plastik.

Abstract

Setiamulya Village is one of the villages that has a Cooperation Agreement (PKS) with the Faculty of Engineering, Siliwangi University. Through PKS, the Faculty of Engineering, Siliwangi University is committed to developing and overcoming problems in society through knowledge developed on campus. The Waste Bank is one of the solutions for the community in Setiamulya Village to overcome the waste problem that occurs in the environment. In its implementation so far, the Setiamulya Village waste bank has carried out the process of separating and storing recyclable waste for further distribution to parties who will recycle the waste. However, due to limitations, the organic waste in the waste bank cannot be utilized. so accumulation still often occurs. With this community service community partnership program, the Setiamulya Village waste bank community group will be provided with knowledge and facilities for processing organic waste through maggot cultivation. So that the organic waste in the waste bank can increase its economic value.

Abstract

The increasing volume of data on the Internet of things (IoT)-based systems has driven the need for efficiency in data management, particularly in air quality monitoring systems. One approach to address this challenge is data duplication detection, which works to eliminate redundant data to reduce storage requirements and power consumption. This study aims to develop an IoT-based air quality monitoring system incorporating a data duplication detection method as part of an effort to support the green IoT concept. The methodology involved a comparative analysis between systems with and without the implementation of data duplication detection, accompanied by a comprehensive evaluation of system performance. The data tested included the size of transmitted data and device power consumption during the transmission process. Testing was conducted under real operational conditions over a 24-hour period. The results indicate that the implementation of data duplication detection successfully reduced the size of transmitted data from 56 bytes to 11–44 bytes, depending on the level of data redundancy. Power consumption was reduced by 1.59% to 3.84% compared to the system without data duplication detection. This method was also proven not to affect the accuracy of the displayed data, thereby maintaining the system’s functional requirements. In conclusion, the implementation of the data duplication detection method in an IoT-based air quality monitoring system not only optimizes data transmission processes but also supports energy efficiency in line with the principles of green IoT. This research provides a significant contribution to the development of more sustainable and energy-efficient IoT systems.

Abstract

Gardu Induk Tasikmalaya menyalurkan energi listrik tegangan menengah 20 kV melalui empat transformator, salah satunya Transformator V yang menyuplai Penyulang TNJG. Penyulang ini sering mengalami gangguan hubung singkat yang menyebabkan trip dan pemadaman, serta berpotensi memicu trip relay incoming 20 kV sehingga berdampak pada penyulang lain. Oleh karena itu, diperlukan koordinasi proteksi arus lebih (OCR) yang tepat antara sisi incoming dan penyulang. Analisis dilakukan melalui perhitungan arus hubung singkat sebagai dasar penentuan setting relay. Hasil perhitungan menunjukkan perbedaan dengan setting eksisting, di mana nilai TMS hasil perhitungan pada Penyulang TNJG sebesar 0,212 s dan incoming sebesar 0,27 s. Seluruh nilai masih memenuhi standar IEC 60255, dan hasil simulasi menunjukkan koordinasi proteksi telah bekerja dengan baik dan selektif.
