Abstract

Pandemi COVID 19 berdampak pada melemahnya kemampuan ekonomi masyarakat yang tergabung dalam Poklahsar Citara Singosari Malang yang mengembangkan budidaya ikan lele pada kolam bio floc. Masalahnya, kemampuan ekonomi yang rendah menyebabkan mereka hanya mampu mengembangkan 4 unit kolam, sehingga hasilnya belum optimal. Untuk mengatasinya, dilakukan kegiatan pengabdian masyarakat ini. Metode pengabdian adalah metode difusi Ipteks untuk menghasilkan kolam biofloc bertenaga surya. Tahapan kegiatan meliputi: menyiapkan lokasi, mendesain, membuat dan memasang kolam biofloc bertenaga surya.  Karya utama berupa 4 unit kolam biofloc bertenaga surya, berdiameter @ 2 m dengan kapasitas 3.000 ekor ikan/kolam. Pompa air kolam digerakkan oleh panel surya berkapasitas 500 WP dan mampu menyala 24 jam/hari. Dampak dan manfaat yaitu terjadi pemberdayaan masyarakat dan lingkungan yang cukup signifikan. Masyarakat mampu mengubah lahan kosong yang tidak produktif menjadi lahan produktif untuk pengembangan budidaya lele biofloc. Jumlah kolam yang semula hanya 4 unit dan berukuran kecil, diameter @ 1,5 m, berkembang menjadi 10 unit berukuran besar, diameter @ 2-4 m, yang semuanya digerakkan oleh pompa air bertenaga surya, sehingga kebutuhan listrik menjadi zero (nol). Perhitungan kapasitas produksi dan omzet budidaya lele naik mencapai  4 kali lipat dari sebelumnya. Kolam biofloc bertenaga surya ini sangat penting untuk meningkatkan kapasitas produksi budidaya lele dan ketahanan pangan masyarakat di masa pandemi, sehingga potensial dikembangkan lagi di kemudian hari.

Abstract

A manufactured product in the form of a mixture of dissimilar materials (bimetal) must be considered, including: selecting the right metal, selecting the appropriate filler, setting the current and voltage, etc. For this reason, research related to bimetallic welding using Gas Metal Arc Welding (GMAW) was conducted. The aims were to determine the effect of current on the tensile strength of bimetallic welding of low carbon steel and stainless steel 304 using GMAW welding, to determine the effect of voltage on the tensile strength of bimetallic welding, and to determine the effect of the interaction of current and voltage on the tensile strength of bimetallic welding using welding. GMAW. The research method used is experimental where the results of bimetallic welding are tested by the destructive test method. The results showed that current, voltage, and the strong interaction between current and voltage affect the tensile strength of bimetallic welding of low carbon steel and stainless steel 304 using GMAW welding. The use of amperes between 120A-160A and a voltage of 19V-22V gives a small difference and a tensile strength of 300 MPa-330 MPa.

Abstract

Wortel merupakan tanaman buah yang juga mengandung vitamin A yang salah satunya bermanfaat bagi mata. Dengan adanya ragam kebutuhan olahan dasar wortel sehingga menjadikan produk olahan wortel meningkat, salah satunya jajanan risol ataupun adonan bubur bayi. Produsen olahan dasar wortel pada industri menengah kebawah masih banyak yang menggunakan cara manual dengan pisau tangan dan membutuhkan waktu yang cukup lama untuk proses perajangan wortel. Tujuan perancangan mesin perajang wortel ini untuk meningkatkan kinerja pada proses perajangan dan mempersingkat waktu produksi dalam usaha olahan bahan dasar wortel.Metode desain dan pembuatan mesin perajang wortel ini meliputi: menentukan mekanisme mesin perajang wortel, perhitungan daya motor yang diperlukan, perhitungan susunan transmisi, perhitungan diameter poros, perhitungan rasio gearbox, pemilihan material, serta pembuatan gambar kerja mesin perajang wortel.Hasil dari desain berupa gambar kerja dan gambar susunan dengan dimensi 940 x 600 x 725 mm, serta material yang dipilih yaitu baja karbon St 37 untuk mendapatkan harga yang ekonomis agar dapat dijangkau oleh industri menengah kebawah dan SS 304 untuk menjaga kualitas produk agar teteap higienis. Total estimasi harga jual mesin perajang wortel kapasitas 75 kg/jam adalah Rp 4.477.000,00.

Abstract

Small PLTS on residential rooftops are now being widely applied. It can contribute to using alternative energy to support government programs to save electricity costs. It can also be used as backup electricity when PLN power outage. The purpose of this research is to be able to calculate the use of electric power in residential homes, design and make small PLTS off grid 240 WP from the use of electric power, calculate BEP when the payback time of the total investment in the procurement of small PLTS 240 WP with DC and AC systems. 240 WP power on the rooftop of a residential house is carried out for a load of 8 lights AC with 6 watts and one fan. This research showed that the total daily electric power usage was 0.55 kWh/day or 16.5 kWh/month. The design of 240 WP PLTS on the rooftop of a residential house according to the total household electricity needs of 550 watts/day requires core equipment such as two solar panels (120 WP), one battery (12 V 100 Ah), Inverter (12 V to 220 V) = 1000 Watt or 1 kWh as much as one piece, SCC = 20 A as much as one piece. The results of making 240 WP PLTS on the rooftop of a residential house accorded to the total electrical power needs of the household. Break Even Point on this application of 240WP solar power PLTS on residential rooftops with 1300 V power will return capital in 19.5 years. Where the total investment cost of procuring 240 WP PLTS is Rp. 5,558,000, and the cost of electricity per month from the above load is Rp. 23,850 / month or Rp. 286,200 / year.

Abstract

Sumberingin Bath is one of the natural tourist destinations located in Wringinsongo Village, Tumpang District, Malang Regency, East Java. This bathing site features a clear and refreshing spring, attracting many visitors from various regions. However, Sumberingin Bath has tourism potential that has not been fully optimized, particularly in the area of night tourism. The objective of this community service project is to develop a decorative lighting area powered by renewable energy at Sumberingin Bath. The methodology employed includes the development of decorative lighting infrastructure, providing training to the community on the management, maintenance, and installation of lights integrated with a solar power system, and creating a selfie tourism program that leverages the beauty of decorative lights to enhance the destination's appeal on social media. The results of this community service initiative offer solutions to the issue of limited lighting and the need to extend the operational hours of the tourist site, while also increasing knowledge and adding value to the location as a renewable energy-based night tourism destination. A total of more than 40 decorative lights were installed, with an average power consumption of 1,200 watts. The energy for these lights is derived from renewable energy stored in a powerwall system with a capacity of 14,400 watts
