No full textKelurahan Mulyorejo merupakan kelurahan yang terletak di wilayah Kecamatan Sukun, kota Malang dengan luas wilayah 2.75 km2. Saat ini, masyarakat Kelurahan Mulyorejo aktif dalam memanfaatkan barang ataupun lahan kosong yang ada pada wilayahnya dengan konsep urban farming. Salah satu urban farming yang dilakukan oleh warga Kelurahan Mulyorejo adalah budidaya bunga telang. Diversifikasi produk yang memiliki nilai jual tinggi dari hasil budidaya bunga telang belum dilakukan secara menyeluruh. Oleh karena itu, penting bagi masyarakat Kelurahan Mulyorejo untuk diberikan pelatihan keterampilan skill agar lebih memahami diverisifikasi produk bunga telang. Salah satu bentuk pelatihan keterampilan yang dapat diberikan kepada masyarakat adalah pembuatan batik berbasis bunga telang sebagai pewarna alami. Pewarna ini memiliki kelebihan yaitu warna bersifat lembut, memiliki nilai jual tinggi dan ramah lingkungan sesuai dengan konsep sustainable development goals yaitu clean water and sanitation. Selain itu, dalam pelatihan ini akan diperkenalkan cara kombinasi warna dari berbagai kombinasi pewarna alam berbasis bunga telang. Pengabdian dilaksanakan pada tanggal 7 Oktober 2023 dengan peserta sebanyak 8 peserta. Berdasarkan hasil kuisioner dapat diketahui bahwa nilai mean mencapai angka 3.88 dan nilai modus dari masing-masing pertanyaan adalah 4.0. Hal ini dapat diinformasikan bahwa peserta pelatihan paham, merasakan manfaat serta puas terhadap pelatihan pembuatan batik dengan pewarna alami berbasis bunga telang. Peserta pelatihan juga mendapatkan alat canting elektrik dari tim pengabdian yang dapat digunakan untuk memproduksi batik secara mandir
Application of Compost APT01 on Apple Crop (10.0-10.5 years)
No full textAbstract— Production of apple tends to decrease because of soil degradation. Objectives of this study are to determine the addition of compostAPT01 to increase fruit production in apple crop.This study aims to analyze the effect of the type and amount of compost APT01 as the soil organic matter to the apple crop production at 3 and 4 months of a day after defoliation and at harvest time (SR3, SR4 and SPN). The experiment was carried out according to completely randomized factorial design with the amount of compost APT01 and the season time of production. The experiment was conducted in 600 square meters. Organic materials of mud cake was fermented for 3 weeks. The amount of compost APT01 as much as 40, 60, and 80 kg per tree was applied a day after defoliation. A total of 27 apple trees aged about 10.0 - 10.5 years with a distance between trees 2-3 meters were randomly selected. Observations made during fruit growth 3 and 4 months after giving compost (SR3 and SR4) and at harvest (SPN). The parameters measured were the number and weight of fruit per tree. Results were analyzed variance, two-way ANOVA with interaction (α = 0.05), using Microsoft Excel. The addition of compost APT01 as much as 40, 60 and 80 kg per tree increasing the number and weight of fruit from initially 5.71 kg (58.84 fruits) to 9.99 kg (95.46 fruits) and 12.12 kg (104.06 fruits) respectively. Moreover, it also improves quality grade in terms of the average fruit produced from 9.56-10.22 fruits/kg (grade AB) to 8.59 fruits/kg (grade AA)
Automation System Simulator With Solid State Relay For The Exchange Of Electrical Energy Sources Between Pln And Generators
No full text70 HalamanGenset akan beroperasi jika suplai dari PLN padam dan genset merupakan suatu mesin/alat yang dapat mengubah energi mekanik menjadi energi listrik dengan diseting/dioperasikan secara otomatis melalui alat Automatic Transfer Switch. ATS ( Automatic Transfer Swicth) adalah saklar otomatis yang dapat memindahakan sumber penyedia tegangan listrik secara otomatis maupun manual .Ditinjau dari teknologi segi peralatan ATS sendiri umumnya masih menggunakan relay elektromagnet sebagai media untuk memindahkan sumber tenaga antara PLN dan Genset hal ini menyebabkan delay waktu ,karena komponen relay elektromagnet itu sendiri membutuhkan waktu untuk menggerakan coilnya. Dalam penelitian dirancang dan dibangun sebuah ATS yang menerapakan Solid State Relay sebagai alat yang digunakan untuk mengatasi waktu delay saat perpindahan arus listrik dari PLN ke Genset atau sebaliknya. Proses pembuatan penulis menggunakan metode eksperimen dan perancangan yang mana dalam proses eksperiment di dapatkan hasil Alat yang dibuat bekerja dengan baik pada pengujian ketika listrik PLN padam ATS menggunakan Solid state Relay ini dapat langsung menggantikan perpindahan dari PLN ke Genset atau sebaliknya. The generator will operate if the supply from PLN goes out and the generator is a machine/tool that can convert mechanical energy into electrical energy by setting/operating automatically through the Automatic Transfer Switch. ATS (Automatic Transfer Switch) is an automatic switch that can move the supply voltage source automatically or manually. In terms of technology, ATS equipment itself generally still uses electromagnetic relays as a medium to move the power source between PLN and Genset this causes a time delay, because the electromagnetic relay component itself takes time to move the coil. In this research, an ATS is designed and built that applies Solid State Relay as a tool used to overcome the delay time when transferring electric current from PLN to Genset or vice versa. The process of making the author uses experimental and design methods which in the experimental process results are obtained. The tool that is made works well in testing when the PLN electricity goes out ATS using this Solid state Relay can directly replace the transfer from PLN to Genset or vice vers
Nature-Inspired Principles for Sustainable Process Design in Chemical Engineering
No full textSustainable chemical processes should be designed to combine the technological advantages and progress with lower safety risks and minimization of environmental impact such as, for example, reduction of raw materials, energy and water consumption, and avoidance of hazardous waste and pollution with toxic chemical agents. A number of novel eco-friendly chemical technologies have been developed in the recent decades with the help of the eco-innovations approaches and methods such as Life Cycle Analysis, Green Process Engineering, Process Intensification, Process Design for Sustainability, and others. An emerging approach to the sustainable process design in process engineering builds on the innovative solutions inspired from nature. However, the implementation of the eco-friendly technologies often faces secondary ecological problems. The study postulates that the eco-inventive principles identified in natural systems allow to avoid secondary eco-problems and proposes to apply these principles for sustainable design in chemical process engineering. The research work critically examines how this approach differs from the biomimetics, as it is commonly used for copying natural systems. The application of nature-inspired eco-design principles is illustrated with an example of a sustainable technology for extraction of nickel from pyrophyllite
