Abstract

Cooling technology plays an important role in daily life, particularly in refrigerators used for storing fruits, vegetables, and beverages. However, conventional cooling systems still use freon, which can damage the ozone layer. This study utilizes the Peltier Effect on the Peltier TEC 12706 module as an environmentally friendly cooling component. The DHT22 sensor is used to measure temperature and humidity, while the NodeMCU ESP8266 processes sensor data displayed through the Blynk application. Three fans are installed outside the cooling chamber to prevent the Peltier module from overheating, and one fan is placed inside the chamber for air distribution. A heatsink is used to assist in heat dissipation. Testing compared the DHT22 sensor with AZ HT-02 and FY-11, producing regression values of R² = 0.9902 for temeprature and R² = 0.9798 for humidity, indicating high accuracy. Using two Peltier TEC 12706 modules and a 12 V 30 A AC-DC adapter, the temperature in the cooling chamber with dimensions (26x17x10) cm was reduced to 19.6°C, with humidity rising to 90.1% within 2 hours. These results show that the developed cooling system can function effectively.

Abstract

Nagari Sunua Barat memiliki potensi limbah sabut kelapa hasil perkebunan kelapa yang melimpah. Kegiatan pengabdian ini bertujuan untuk memberdayakan kelompok tani di Nagari Sunua Barat melalui pelatihan pengolahan limbah sabut kelapa menjadi cocopeat dan cocofiber, yang lebih memiliki nilai ekonomis dan ramah lingkungan. Kegiatan pengabdian kepada masyarakat dilakukan oleh tim dari Fakultas Matematika dan Ilmu Pengetahuan Alam, dimulai dengan tahap perencanaan yang melibatkan mitra kelompok tani untuk mengidentifikasi kebutuhan dan potensi yang ada pada mitra. Kegiatan ini diikuti oleh 47 peserta yang berasal dari kelompok tani dan masyarakat yang ada di Nagari Sunua Barat. Peserta diajarkan tentang pengelolaan sampah limbah sabut kelapa, yang dimanfaatkan menjadi cocopeat dan cocofiber. Metode yang digunakan meliputi demonstrasi, praktik langsung, dan diskusi interaktif. Hasil dari kegiatan menunjukkan antusiasme yang tinggi dari peserta. Sebagian besar mampu memahami dan mempraktikkan teknik yang diajarkan, dengan beberapa peserta mulai memproduksi cocopeat dan cocofiber untuk keperluan pribadi maupun komersial. Pelatihan ini berhasil meningkatkan kesadaran masyarakat akan pentingnya pengelolaan limbah yang berkelanjutan serta memberikan peluang ekonomi baru bagi kelompok tani. Kegiatan ini diharapkan dapat menjadi langkah awal untuk menjadikan Nagari Sunua Barat sebagai sentra pengolahan limbah sabut kelapa, sekaligus mendorong terciptanya masyarakat yang lebih peduli lingkungan dan mandiri secara ekonomi

Abstract

The fashion industry in Indonesia significantly contributes to the country’s creative economy. However, public knowledge about various types of fabric materials is still limited, often leading to fraud. This research aims to develop a device that can classify fabric materials based on their structure using computer vision techniques. The device uses a digital microscope endoscope magnifier 1600x USB camera to capture fabric structure images and the YOLOv8 algorithm to classify 17 types of fabric materials from 1,700 raw image data. The research methodology includes collecting fabric image datasets, preprocessing data, and training the YOLOv8 model. The results show that the YOLOv8 model achieves an accuracy of 98%. The classification results are displayed on an LCD connected to NodeMCU ESP8266. System testing shows that the device effectively classifies fabric materials, sends the results to the database via API, and displays the results on the LCD. Overall, this device provides an effective solution for distinguishing types of fabrics and preventing fraud in fabric purchases.

Abstract

Electricity is essential for everyday needs, including food preservation through refrigeration. However, access to electricity remains uneven in remote regions due to geographical constraints. Solar energy offers a promising alternative, especially in areas with abundant sunlight, highlighting the need for compact, portable, and eco-friendly cooling system. This study aims to design an eco-friendly cooling system using the Seebeck Effect in Peltier TEC 12706 modules powered by solar energy. The system consists of two Peltier TEC 12706 modules, a 50 Wp solar panel, and a 33 Ah accumulator, with a cooling chamber measuring 26 × 17 × 10 cm. Temperature and humidity were remotely monitored via the Blynk application. Experimental results showed the lowest temperature achieved was 15°C between 08:00 AM and 10:00 AM. In comparison, the most significant temperature drop of 11.7°C occurred between 12:00 PM and 02:00 PM, with an average light intensity of 176,846.15 Lux. Although the system demonstrated cooling performance, the minimum temperature of 15°C does not meet the standard refrigeration temperature of around 0°C. Therefore, the current system is not yet suitable for replacing conventional refrigerators, but it shows potential as an environmentally friendly alternative cooling solution with further development.

Abstract

Kegiatan pengabdian ini dilaksanakan di Nagari Persiapan Lubuk Gadang Tenggara, Solok Selatan, yang sebagian besar wilayahnya berada dalam kawasan Taman Nasional Kerinci Seblat (TNKS). Masyarakat menghadapi persoalan mendasar berupa ketidakjelasan status hukum kawasan, lemahnya kelembagaan lokal, terbatasnya akses terhadap hasil hutan bukan kayu, serta defisit kepercayaan terhadap otoritas konservasi. Untuk menjawab tantangan tersebut, digunakan metode Participatory Rural Appraisal (PRA) melalui pemetaan sosial, diskusi kelompok terarah, dan fasilitasi dialog multipihak. Hasil kegiatan menunjukkan bahwa forum partisipatif mampu mengidentifikasi potensi lokal, memperkuat kebutuhan pembentukan Kelompok Tani Hutan (KTH) dan Forum Nagari Konservasi (FNK), serta membuka ruang negosiasi yang lebih adil antara masyarakat dan TNKS. Temuan ini menegaskan pentingnya komunikasi deliberatif dan kemitraan konservasi yang inklusif, agar konservasi tidak hanya melindungi ekosistem tetapi juga meningkatkan kesejahteraan masyarakat.
