Abstract

The need for a high resolution to the thermal image is urgent and essential. The high resolution of the thermal image can give accurate information on the heat distribution map of the objects. The accurate heat distribution maps can give accurate temperature information. This accurate temperature measurement is used for measuring many objects such as electric motors, engines, the human body, and so on—this information is used to detect the anomalies of the object to find the damaged parts. The anomalies are considered damaged parts found in solar panels, agricultural fields, buildings, bridges, etc. As the super-resolution of thermal images is very important, generating them is compulsory. The camera for obtaining super-resolution thermal images is rare, not available in the common market. Furthermore, this kind of device is costly too. Therefore not all the users, such as farmers or technicians, can have them. In order to handle the problem, the proposed method has the purpose of generating super-resolution thermal images economically and is more accessible through the deep learning method. The dataset is taken from the solar panel. The results show that the proposed method can handle the low-resolution problem of thermal images.

Abstract

Since the pandemic two years ago, The schools have mostly conducted teaching and learning activities online. Students are provided with teaching materials in the form of documents or videos to follow the teaching materials. Of course, a cellphone is a basic requirement for students to be able to interact online with teachers. Most students as internet users use cell phones more than using laptops or internet cafes, but only for browsing, chatting with social media applications or playing online games so that it is time consuming, but not enabled for self-creativity. Therefore, an understanding is given to students so that cellphones are used optimally apart from being a formal learning medium, they are also enabled to develop their own creativity or educate themselves using digital technology by creating content that can be used as a business or online business. One of them is through the KUNCIE application, students can learn to start a business as beginners, learn from mentors who are experts in their respective fields to convey how digital-based hobbies can be used as self-potential for creativity.

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

Environmental parameters in a greenhouse influence plant growth, namely sunlight, air temperature, air humidity, which can be controlled more easily. Using a greenhouse allows you to get closer to optimal conditions for plant growth. A plant can generally grow in a warm and humid environment. Therefore, keeping plant seeds in a warm growing environment will speed up the plant growth process. Apart from the above parameters, it is also necessary to pay attention to disturbances from destructive animals at night which disturb fruit and vegetable crops. Since the existence of the green house, KWT has been active in helping the family's economy by planting vegetables such as soycin, celery, leeks, lettuce, eggplant and tomatoes. However, at night the Green House has no lighting. Because the green house is on empty land surrounded by weeds, there have been several incidents where animals have entered the green house and disturbed or damaged the plants, such as rats and raccoons. And it would be a shame if these plants were already bearing fruit like tomatoes and eggplant. Therefore, greenhouses need lighting in addition to maintaining temperature or warm conditions to speed up the seeding process and also to protect the plants in the greenhouse from nocturnal animals that damage fruit and vegetable plants. The team offers automatic lighting technology. also equipped with automatic watering.

Abstract

Khadijah Food are experiencing obstacles related to the Banana Sale production process which still uses traditional methods in drying raw materials through direct sunlight. Actually, this partner already has an oven dryer, but the performance of the tool is not optimal because the production results and the quality of the dried bananas are not as expected, because the caramelization process, which is an important stage in drying bananas, does not go well. The solution provided is to use a food drying device using the concept of drying moisture content with a heating element for drying, and a blower for heat circulation in the drying room, so that the drying results of bananas can run more optimally because apart from the heat from the heater, sufficient air circulation is also provided in the drying process. Drying banana ingredients with a concept like this will allow the caramelization stage to run optimally because the water content will not be trapped on the surface of the banana or evaporate. Caramelization is a reaction of sugar content to high heat temperatures which results in bananas becoming more pliable or not easily brittle, brownish in color and having a distinctive taste. With this service activity, partners benefit directly through the touch of technology provided. An increase in turnover will occur and market needs will also be met even though the weather is not supportive.

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.
