Abstract

Laundry workers are required to be able to fold quite a lot of clothes in a fairly short time and neatly. Based on this, an innovation is needed in terms of folding clothes that can help household chores and the UMKM scale laundry industry in terms of folding clothes. The main aim of the research is to create an Arduino-based automatic clothes folding device. Arduino Uno is a microcontroller that is often used in making prototypes of electronic circuits which are useful for making things easier for users. Making an Arduino-based module requires a circuit schematic which is useful for making things easier when making tools. Electronic circuit schematics are needed as a guide in making electronic circuits. The electronic circuit schematic should be designed or drafted first before carrying out the process of making the electronic circuit. Testing of this servo motor is carried out by starting the rotation of the servo motor from an angle of 0⁰ to a rotation of 180⁰. The test results can be concluded that the three servo motors used are in good condition. Having an automatic clothes folding tool can help with daily housework and help laundry entrepreneurs in folding clothes neatly, saving time and energy. The time required to fold a short-sleeved t-shirt is 3.56 seconds and a short-sleeved shirt is 3.66 seconds

Abstract

Monitoring shrimp ponds involves observing and measuring key environmental factors that influence shrimp health and growth. This study was conducted at a shrimp pond on Jalan Paluh Merbau, Tj. Rejo, Kec. Percut Sei Tuan, Deli Serdang Regency, North Sumatra, Indonesia. Traditionally, air humidity and water temperature are monitored manually by taking water samples for laboratory analysis or using litmus paper. These conventional methods are time-consuming and prone to inaccuracies, potentially compromising shrimp health. To address these challenges, this research implemented an Internet of Things (IoT)-based monitoring system to automate the measurement of air humidity and water temperature. The system utilizes DHT11 and DS18b20 sensors, integrated with an ESP32 module, to continuously collect data and automatically transmit it to Google Sheets for real-time monitoring. This IoT approach enables shrimp farmers to easily track water quality parameters, enhancing the accuracy and efficiency of pond management. A two-day testing phase demonstrated stable environmental conditions, with humidity levels recorded at 86.5% to 87.78% and water temperatures ranging from 27.55°C to 28.06°C. These readings were within the ideal thresholds for optimal shrimp growth, showcasing the system's effectiveness in maintaining suitable pond conditions. This research will contribute significantly to more efficient, accurate, and sustainable shrimp farming practices.

Abstract

Abstrak: Tanaman sagu (Metroxylon sp.) merupakan komoditas pangan kaya karbohidrat yang menjadi bahan pokok di beberapa wilayah Indonesia. Kegiatan pengabdian masyarakat ini melibatkan 10 orang peserta petani sagu di Desa Durian Lingga. Kegiatan PKM ini bertujuan untuk meningkatkan keterampilan teknis (hardskill) petani dalam pengolahan limbah sagu menjadi pakan ternak dan pembuatan alat pencacah, serta mengembangkan kemampuan manajerial (softskill) dalam pemasaran produk. Metode pelaksanaan menggunakan pendekatan partisipatif melalui ceramah interaktif, pelatihan praktik langsung, focus group discussion (FGD), dan pendampingan intensif. Untuk sistem evaluasi dilakukan dengan Observasi langsung dan Uji kinerja alat Pencacah tersebut. Selain sebagai sumber pangan, sagu memiliki multi-fungsi karena seluruh bagian tanamannya dapat dimanfaatkan. Pelatihan pengolahan sagu menjadi pakan ternak ini menjadi solusi strategis untuk mengatasi masalah limbah pertanian sekaligus meningkatkan pendapatan petani melalui diversifikasi produk. Namun, petani sagu di Desa Durian Lingga masih menghadapi kendala berupa kurangnya pengetahuan teknis dan keterampilan manajerial. Kegiatan ini penting untuk membangun kemandirian petani dalam mengelola sumber daya lokal secara berkelanjutan. Tim pengabdian masyarakat melaksanakan pelatihan praktis yang mencakup: pengolahan sagu menjadi pakan ternak, pembuatan alat pencacah sagu, serta manajemen pemasaran. Dampak jangka panjangnya adalah peningkatan ekonomi sekitar 85% masyarakat melalui pengoptimalan potensi lokal dan penguatan kelembagaan petani berbasis agribisnis.Abstract: Sago plants (Metroxylon sp.) are a carbohydrate-rich food commodity that is a staple food in several regions of Indonesia. This community service activity involved 10 sago farmer participants in Durian Lingga Village. This PKM activity aims to improve farmers' technical skills (hard skills) in processing sago waste into animal feed and making shredders, as well as developing managerial skills (soft skills) in product marketing. The implementation method uses a participatory approach through interactive lectures, direct practice training, focus group discussions (FGD), and intensive mentoring. For system evaluation, direct observation and performance testing of the shredder tool are carried out. In addition to being a food source, sago has multiple functions because all parts of the plant can be utilized. This training in processing sago into animal feed is a strategic solution to overcome the problem of agricultural waste while increasing farmers' income through product diversification. However, sago farmers in Durian Lingga Village still face obstacles in the form of a lack of technical knowledge and managerial skills. This activity is important to build farmer independence in managing local resources sustainably. The community service team conducted practical training that included: processing sago into animal feed, making sago shredders, and marketing management. The long-term impact is an increase in the economy of around 85% of the community through harmonization of local potential and strengthening of agribusiness-based farmer institutions.

Abstract

This study was conducted to determine how much influence EVA (Ethylene Vinyl Acetate) added to Laston AC-BC has on Marshall characteristic values. The Marshall test carried out will produce stability values at the optimum asphalt conditions that meet the 2018 Highways specifications. The stability value will be used to analyze changes in the characteristics of the Laston AC-BC (Asphalt Concrate – Binder Course) mixture after adding a mixture of EVA (Ethylene Vinyl Acetate) . To determine an aggregate gradation in the AC-BC mixed layer, coarse aggregate is used in the form of crushed stone with a maximum size of ” while for fine aggregate it is a mixture of crushed stone, stone ash and sand. The additive or modifier used is EVA (Ethylene Vinyl Acetate) polymer. Next, to obtain good asphalt concrete, the gradation of the aggregate must meet the general specifications of Bina Marga 2018 which have been determined through SNI-ASTM-C136-2012. In making the test object, ± 1200 gram of aggregate and asphalt are needed so that the specified height of the test object will be produced. Through the analysis of the aggregate sieve, the weight of the aggregate required for the test object can be calculated. Modification of asphalt with EVA aims to determine the stiffness and properties of asphalt in resisting loading with a certain penetration value so as to produce a Penetration Index value which will affect the characteristics of asphalt against weather changes. Research and knowledge related to the addition of a mixture of EVA (Ethylene Vinyl Acetate) to asphalt can be further developed so that it can be implemented on types of road pavements with higher traffic density conditions.

Abstract

Designing the utility planning concept for the Ampera Medan road corridor, it starts with identifying the condition of the drainage system, traffic signs, road markings, public road lighting, and road user safety devices. Furthermore, a study of changes to road utility requirements is carried out by road management guidelines and road environmental conditions in the form of improving kindness on the road surface, installing signs and warning devices, installing flashing lights, removing roadblocks, and installing noise tape based on certain distances. This research aims to produce a design concept for road utility planning that is environmentally friendly and sustainable (sustainable road) under the guidelines of the Ministry of PUPR while still paying attention to basic human needs and economic growth. Research and knowledge related to the concept of environmentally friendly road utility planning on the Jalan Ampera Medan corridor is a contribution to scientific work that can provide benefits to the Muhammadiyah University of North Sumatra and the Medan City Government as material for consideration and decisions in the construction of environmentally friendly roads (green roads) in the city Medan.
