Abstract

Studying and understanding technological developments is also one of the teacher's obligations. Today , as a teacher, it is necessary to utilize media or applications to improve the quality of learning. The development of information technology and computers is now taking place very quickly. Almost all fields of work and activities around us are always associated with systems connected to information technology and the use of computers. So that mastery of computer applications is absolutely necessary for anyone who wants to complete a field of work or activity more easily and quickly. The field of Engineering expertise is currently experiencing very rapid development, especially in the field of product design and design optimization. In the industrial world, the design process for a product no longer uses conventional methods, but uses a computer facility through a design and optimization software which is commonly referred to as CAD (Computer Aided Design). Multinational manufacturing companies have applied this technology and one of them is the AutoCAD application which can facilitate the creation of technical drawing learning. Mastery of the AutoCAD software application is very important for vocational students, especially to welcome global competition that can be used for engineering drawing. The current problem faced by teachers is how to install and run the AutoCAD application. AutoCAD is application software that is widely used in the domestic and foreign industrial world, so learning this application will provide many benefits for teachers and students, especially at SMK 5 Padang.

Abstract

Coffee is categorized into three types Robusta, Arabica, and Liberica. The roasting process is the most crucial step in developing the aroma, flavor, and underlying color that determine coffee quality. The coffee roasting process produces complex aroma compounds that impart the desired taste and aroma characteristics of coffee. This research aims to design a coffee content detection tool by determining the carbon monoxide (CO) level in Arabica, Robusta, and Liberica coffee. The research uses the Backpropagation artificial neural network method with 2 hidden layers, including 4 input layers and 3 output layers, to identify the tested coffee varieties. The highest carbon monoxide (CO) levels were found in Arabica Special coffee, with an ADC level of 662 carbon monoxide gas. The lowest carbon monoxide (CO) levels were detected in Liberica coffee, with an ADC level of 105 carbon monoxide gas. Coffee identification was carried out using an artificial neural network method with a success rate of 98% for Liberica coffee, 100% for Arabica coffee, and 98% for Robusta coffee.

Abstract

Sale pisang is a typical Indonesian food made from dried bananas. Usually, this drying is done by drying directly in the sun. Drying bananas in the sun is not very effective because it takes a long time and is very dependent on weather conditions. After innovation was made by making a dryer, sale pisang was produced which had a hard texture and low moisture content that affected the caramelization process. Therefore, a dryer is needed that can replace the drying process under the sun. One of the contents of sunlight is ultraviolet light. Irradiation of ultraviolet light, especially UVC light, can help shrink the cell wall of bananas so that the evaporation of water during drying is small. This study aims to identify good UV levels for the caramelization process to produce the same sale pisang as drying under the sun using 5 different treatments, namely, without UV lighting, 15 minutes irradiation, 30 minutes irradiation, 1-hour irradiation, and 2 hours irradiation. Irradiation for 15 minutes produces a water content of 11%, irradiation for 30 minutes produces a water content of 12%, irradiation for 1 hour produces a water content of 18%, and Sale pisang with irradiation for 2 hours produces a water content of 20%. Based on the texture analysis produced by irradiation for 1 hour produces a texture that is almost the same as drying directly under the sun.

Abstract

Kelompok tani di Sungai Buluh memanfaatkan lahan yang dimiliki oleh beberapa anggota untuk ditanami tanaman cabe. Pengelolaan lahan tanaman cabe ini dilakukan secara rutin setiap hari oleh semua anggota kelompok tani secara bergantian mulai dari pembibitan, pemupukan, penyiraman, dan penyemprotan pestisida. Proses penyemprotan pestisida dilakukan menggunakan alat bernama Tasco yang disandang pada punggung dan disemprot ke tanaman cabe satu per satu secara manual dengan menekan tuas pada bagian bawahnya. Dilihat dari kondisi tasco yang sering tersendat atau macet sehingga proses penyemprotan pestisida menjadi terhambat. Oleh karena itu, tim mengupayakan tawaran teknologi yang memudahkan kelompok tani untuk proses penyemprotan pestisida tanaman cabe otomatis dengan motor pompa 12 volt yang dikendalikan secara otomatis menggunakan mikrokontroler. Sumber listrik diupayakan dari solar sel yang akan mencukupi daya penyemprotan. Tawaran teknologi ini sangat bermanfaat bagi kelompok tani yang rutin melakukan penyemprotan pestisida

Abstract

Salah satu kelompok pemberdayaan perempuan untuk melerstarikan pekarangan lingkungan sekitar di lahan pangan lestari dengan nama kelompok wanita tani Demplot di kelurahan Lubuk Begalung. Lahan kosong berukuran 500 meter persegi dimanfaatkan oleh ibuk-ibuk yang bergabung dalam KWT-Demplot untuk bercocok tanam sayuran. Ketua kelompok pangan lestari ini di koodinir oleh ketua RT setempat. Pengelolaan lahan sayuran ini dilakukan bergantian secara rutin setiap hari oleh ibu-ibu mulai dari pembibitan, pemupukan, pembersihan dari hama rumput serta penyiraman.Rumput liar dapat menjadi masalah serius bagi pertanian dan kebun jika tidak segera diatasi. Beberapa rumput liar dapat berkembang biak dengan cepat melalui biji, sementara yang lain dapat merambat. Tanah yang sehat dan subur dapat memberikan keunggulan bersaing terhadap rumput liar. Memastikan tanah terbebas dari rumput liar dengan menjaga kelembaban tanah atau mencegah genangan air dan memberikan nutrisi yang tepat untuk tanaman utama adalah langkah kuncinya. Cara mengatasinya tanpa terganggu dengan rumput tersebut dengan penyiangan secara rutin dengan cara manual untuk mengendalikan pertumbuhan rumput liar. Ini mencakup mencabut rumput liar secara manual atau menggunakan alat penyiangan tanah. Tim mengamati bahwa pekerjaan ini memang membutuhkan waktu dan tenaga yang melelahkan, kemudian dilihat dari kondisi rumput yang subur tumbuh. Oleh karena itu, tim mengupayakan tawaran teknologi yang memudahkan ibu-ibu untuk proses pemotongan rumput liar dari tanaman sayuran. Solusinya dengan memodifikasi mesin potong rumput yang ada dengan mesin potong rumput berdaya baterai sehingga ringan dibawa-bawa selama pemotongan rumput.
