Abstract

Pembuatan Kipas Angin Otomatis yang dikendalikan oleh suhu ruangan dan gerak manusia, dilatarbelakangi oleh perkembangan alat teknologi yang sangat pesat di jaman modern ini. Khususnya alat elektronik yang banyak digunakan untuk membantu meringankan pekerjaan manusia, sehingga besar akan kebutuhan listrik. Sedangkan sumber atau pembangkit arus listrik sangat terbatas. Penghematan merupakan salah satu solusi mengatasi besarnya pemakaian arus listrik. Untuk dapat mengoptimalkan penghematan listrik, maka dapat dilakukan dengan beralih pada alat elektronik yang bersifat otomatis atau membuat rancangan elektronik lainnya seperti halnya Kipas Angin Otomatis. Kipas Angin Otomatis menggunakan mikrokontroler Atmega8 yang mengendalikan sistem kipas angin berdasarkan suhu ruangan dan gerak manusia. Sensor yang digunakan adalah passive infrared receiver yang mendeteksi perubahan infra merah pasif.

Abstract

Proyek akhir buka tutup bak sampah menggunakan mikrokontroler AT89S52 ini dirancang untuk memudahkan pengguna dalam membuang sampah pada tempatnya tanpa harus menentukan jenis sampah dengan manual. Dalam hal ini sampah dipilih berdasarkan sampah logan dan non logam. Metode yang digunakan untuk mendeteksi keberadaan obyek ini adalah metode rancang bangun yang menggunakan sensor metal dan motor penggerak jenis DC ini terbagi menjadi dua bagian, yaitu bagian hardware dan software. Hardware terdiri dari sensor metal, sensor infra merah, sistem minimum mikrokontroler AT89S52 sebagai rangkaian pengendali input dan output, 4N25 sebagai IC driver motor dc. Sedangkan software yang dibuat menggunakan program 8051. Unjuk kerja tempat sampah otomatis menggunakan mikrokontroler AT89S52 ini secara keseluruhan dapat bekerja dengan baik, sehingga efektif memilih jenis sampah.

Abstract

KKM UNIBA Group 1 Lebak Wangi Village conducted ecoprint training activities on tote bags in Lebak Wangi Village, Walantaka Sub-district, a creative and sustainable initiative that aims to empower local communities, especially women, in developing new skills in the field of handicrafts. Ecoprint is a natural dyeing technique that utilizes organic materials such as leaves, flowers and twigs to create unique motifs on fabric. The training was designed to introduce the eco-friendly ecoprint method, as well as provide an economic alternative for the villagers through the production of tote bags that can be sold as local products. The results of this training showed that the participants were able to master the basic ecoprint techniques and produce tote bag products that have aesthetic and commercial value. In addition, this activity also encourages awareness of the importance of protecting the environment through the use of natural materials and production processes that minimize waste. Thus, the ecoprint training in Lebak Wangi Village is not only a means of developing skills, but also plays a role in efforts to preserve the environment and improve the economic welfare of the local community.

Abstract

Electromigration is a critical issue in materials science and electrical engineering, significantly impacting the reliability and efficiency of electrical systems. This study investigates the electromigration behavior of PVC-insulated copper wires under various overcurrent conditions, focusing on material degradation and electrical performance. Copper cables, identified as 046620.3 Eterna CU/PVC 1.5 mm2, were subjected to currents ranging from 0 to 110 A. The mean time to failure (MTTF) was calculated using Black’s equation, revealing a sharp decline in MTTF with increasing current density. Surface morphology analysis using SEM showed the formation of voids and hillocks at higher currents, indicating severe electromigration damage. XRF analysis demonstrated significant changes in the elemental composition, particularly a reduction in copper content and an increase in chlorine and other elements, suggesting degradation of the PVC insulation. FTIR spectroscopy revealed substantial chemical changes in the PVC material, especially under extreme overcurrent conditions, highlighting dehydrochlorination and carbonyl group formation. There is a clear relationship between overcurrent conditions and electromigration phenomena, as evidenced by the observed damage to surface morphology, changes in elemental composition, and alterations in the chemical structure of PVC. The mechanisms and causes of electromigration are explained comprehensively in this work, illustrating how increased overcurrent accelerates the electromigration process, leading to the formation of voids and hillocks in the copper conductor. This damage is accompanied by a significant reduction in copper content and an increase in chlorine levels, indicating the degradation of PVC insulation. FTIR spectra further confirmed these findings by showing chemical changes such as dehydrochlorination and carbonyl group formation under high current stress. The MTTF values reflect the severity of these impacts, with samples exposed to higher currents showing drastically reduced lifespans. For instance, samples subjected to 100 A and 110 A currents exhibited MTTF values of 0.2 minutes and 0.004 minutes, respectively.

Abstract

Photovoltaic (PV) installations and wind turbines that are installed on the rooftops of buildings need to be protected because the layout is in a high position and there is a risk of being struck by lightning. Therefore, a more effective protection system is designed to anticipate electronic damage and fire on all materials in the distribution network, especially the addition of PV and wind turbine installations on building roofs. The purpose of this study is to simulate a lightning protection system on the distribution network and the results of on-grid PV energy conversion using electrical transient analyzer program (ETAP) software. Feeder relay delay times and cascade coordination patterns between outgoing and incoming relays do not overlap. the delay time of the relay working on the feeder is 0.31 s and the coordination pattern of the outgoing relay and incoming relay does not touch each other, so the delay time for the incoming relay is 2.73 s. Then testing the results of PV energy conversion connected to the grid using MATLAB Simulink monitoring obtained data reaching 1.600 Wp at peak power with sun conditions parallel to the PV installation layout.
