Abstract

Coffee, one of Indonesia's largest commodities, is often processed using traditional methods and tools that rely heavily on manual labor and can be labor-intensive. To make the coffee roasting process more efficient and reduce the need for human effort, a coffee roasting machine can be used. This study aimed to analyze coffee roasting drums using computational fluid dynamics (CFD) to determine the optimal drum thickness and rotation speed in a coffee roasting machine. The study considered three different thicknesses (1mm, 2mm, and 3mm) and three different rotation speeds (60rpm, 65rpm, and 70rpm). The coffee roasting drum was modeled using CFD. The study's results showed that a drum thickness of 2mm and a rotation speed of 70rpm achieved the best heat distribution during roasting, reaching the desired temperature in 900 seconds. This information could be used to design a more efficient coffee roasting machine or improve the performance of existing machines.

Abstract

Energi merupakan salah satu masalah utama yang dihadapi oleh hampir seluruh negara di dunia. Hal ini mengingat energi merupakan salah satu faktor utama bagi terjadinya pertumbuhan ekonomi suatu negara. Permasalahan energi menjadi semakin kompleks ketika kebutuhan yang meningkat akan energi untuk menopang pertumbuhan ekonominya justru membuat persediaan cadangan energi konvensional menjadi semakin sedikit. Seiring dengan bertambahnya jumlah penduduk, maka kebutuhan energi listrik juga akan bertambah. Pembangkit yang ada di Indonesia masih terbatas pada umumnya berasal dari energi air, panas bumi, dan batu bara sedangkan pemanfaatan Energi yang lainnya, misalnya energi listrik yang berasal dari sinar matahari jarang digunakan. Berdasarkan permasalahan tersebut, energi surya dipilih sebagai energi alternatif untuk produksi listrik. Untuk dapat memanfaatkan energi matahari secara terus menerus baik siang maupun malam, energi listrik yang dihasilkan terlebih dahulu disimpan dalam baterai yang dikendalikan oleh pengontrol. Output dari pengontrol dihubungkan langsung ke inverter DC ke AC. Jadi apabila listrik dari PT PLN padam maka lampu di dalam rumah tidak akan padam, selain itu khusus untuk penerangan dan beban kecil tenaga surya sehingga mengurangi pembelian token listrik dan menjadi lebih efisien. Biaya pemakaian listrik per hari dalam setahun rata-rata 365 hari, maka harga listrik sebesar Rp. 558.450,-. dan biaya pembelian peralatan energi surya yaitu Rp. 5.425.000, akan kembal modal (break even point) dalam waktu 9,71 tahun. Hasil penelitian bahwa energi listrik yang digunakan untuk keperluan lampu penerangan dan beban dalam rumah sederhana di penelitian ini, rata-rata perhari memerlukan energi listrik sebesar 1,132 kWh. Kemudian setelah dikonversikan dengan Tarif Dasar Listrik (TDL) yang berlaku yaitu Rp. 1.352 per kWh, biaya untuk pemakaian listrik setiap harinya adalah sebesar Rp. 1.530,- dan dalam setahun rata-rata terdiri dari 365 hari, maka biaya listrik yang digunakan dalam waktu setahun adalah sebesar Rp. 1.530,- x 365 hari = Rp. 558.450,-. Jadi biaya pengadaan perangkat solar cell untuk keperluan rumah tinggal yang sesuai dengan beban yang ada yaitu sebesar Rp. 5.425.000,-, akan kembali modal dalam waktu 9,714 tahun.

Abstract

The creation, transmission, distribution, and consumption of electrical energy are the first steps in the provision of electrical energy. The efforts that are made to conserve energy need to be continuously improved to supply electricity that is affordable. In order to conserve energy, it is necessary to have the backing of technology, laws, and legislation, in addition to applying behavioral discipline to those who utilize energy. To put it simply, a smart energy meter is one of the fundamental components of conservation technology. At the moment, the bulk of PLN's 67.6 million clients make use of traditional energy meters that are powered by electromechanical technology. The measuring device has not been incorporated with the technology that is associated with the internet of things (IoT). On the other hand, electronic items like televisions, washing machines, and air conditioners have started to adopt the Internet of Things and become smart devices. The integration of smart gadgets and smart meters enables the creation of an energy management system that can be used to the consumption and distribution of electricity in residential or commercial facilities. At Tiara Sella Hospital, which has a high monthly energy consumption, this community service project was carried out in order to measure the optimization of energy use and to determine opportunities for improvement. It is believed that the installation of this energy meter would result in improved and more reliable methods of measuring and estimating the amount of energy that is utilized within the hospital setting, which will allow for more sustainable optimization efforts.
