ns as it depends on weather conditions, requires 2–3 days, and produces products that are less hygienic and inconsistent in quality. The purpose of this activity is to provide a solution through mentoring and training in the use of the electric emping melinjo dryer (KEPINGJO) so that partners are able to operate the equipment and increase production capacity. The implementation method includes several stages: preparation, technology socialization, training, trials, evaluation, and mentoring. The results show that the partners actively participated and were able to operate the equipment independently. The use of the electric dryer resulted in a reduction from 1 kg to 0.64 kg within 1 hour at a temperature of 55 °C, which is much faster than the traditional drying method that takes 2–3 days. In addition, the moisture content of emping melinjo, initially 29% in the wet condition, decreased to 9.5% after the drying process using the electric dryer. The final product is more hygienic, evenly dried, and has a longer shelf life. The application of the KEPINGJO electric dryer has proven to increase productivity, product quality, and household income while strengthening the role of universities in delivering appropriate technological innovations.

Abstrak: Kegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh permasalahan pengeringan emping melinjo di Kecamatan Perbaungan, Kabupaten Serdang Bedagai, yang masih mengandalkan sinar matahari. Metode tersebut memiliki banyak keterbatasan karena bergantung pada cuaca, membutuhkan waktu 2–3 hari, serta menghasilkan produk yang kurang higienis dan tidak seragam. Tujuan kegiatan adalah memberikan solusi melalui pendampingan dan pelatihan penggunaan alat pengering elektrik emping melinjo (KEPINGJO) agar mitra mampu mengoperasikan dan meningkatkan kapasitas produksi. Metode pelaksanaan meliputi tahap persiapan, sosialisasi teknologi, pelatihan, uji coba, serta evaluasi dan pendampingan. Hasil kegiatan menunjukkan mitra aktif berpartisipasi dan mampu menggunakan alat secara mandiri. Penggunaan alat pengering elektrik memperlihatkan penyusutan dari 1 kg menjadi 0,64 kg dalam waktu 1 jam pada suhu 55 °C, jauh lebih cepat dibanding metode tradisional 2–3 hari. Selain itu, kadar air emping melinjo yang semula sebesar 29% pada kondisi basah menurun menjadi 9,5% setelah proses pengeringan menggunakan alat pengering elektrik. Produk yang dihasilkan lebih higienis, kering merata, dan memiliki daya simpan lebih lama. Penerapan pengering elektrik KEPINGJO terbukti meningkatkan produktivitas, kualitas, serta pendapatan rumah tangga, sekaligus memperkuat kontribusi perguruan tinggi dalam menghadirkan inovasi tepat guna.

and efficient feeding. One of the main problems faced by the group is the difficulty in maintaining optimal water temperature and quality as well as manual feeding management. To overcome this problem, it is necessary to implement Internet of Things (IoT) technology integrated with an Android application. This technology allows monitoring of pond conditions such as water temperature and pH automatically, as well as periodic fish feeding settings. This community service aims to build IoT-based automatic monitoring tools and systems, as well as provide training and mentoring to members of the Jabal Farm Taruna Tani Group in using IoT technology for fish pond management. The implementation method in this activity uses a Participatory Rural Appraisal (PRA) approach that emphasizes active community participation in all stages of the activity, from problem identification to evaluation and follow-up. With IoT technology, it is expected that fish pond management patterns will become more modern and efficient. This technology can help improve fish farming performance, reduce risks, and facilitate management, thus having a positive impact on the productivity and welfare of farmers.

of land preparation, seed placement, and corn covering not occurring simultaneously. By providing training and direct assistance to partners on the use of corn seed planting tools, it can improve their understanding and skills in using the tool effectively. By conducting socialization methods to provide understanding to partners with the aim of the community understanding the use of corn seed planting tools based on the double seed hopper and understanding how to maintain the tool. Thus, with this tool, the corn seed planting process becomes faster. Corn planting is the most widely produced crop in the world, and corn seed plants are most suitable for planting in high-temperature areas. Especially in Indonesia, corn plants cover more than 100 million hectares, consisting of 70 countries and even 53 developing countries. The tool being socialized is a simple tool that is used with human power by pushing without the use of motorized equipment. In the planting process, the spacing between corn seed plants and the number of corn seeds can be adjusted during the planting process. The vessel or container supplying corn seeds is a hopper located at the top, and a hole is provided at the bottom of the hopper, which is the outlet channel. Thus, the results of this socialization can shorten the time in the corn seed planting process.

hich enables devices to be interconnected through the internet to perform monitoring and data exchange in real time. In hydroponic cultivation, water quality stability is a crucial factor that affects plant growth. The main parameters that need to be monitored include water acidity level (pH), water temperature, and dissolved nutrient concentration measured using Total Dissolved Solids (TDS). However, water quality monitoring is still commonly conducted manually, making it less efficient and potentially causing delays in detecting changes in water conditions. This study aims to design an IoT-based water quality monitoring system for hydroponic cultivation using an ESP32 microcontroller integrated with pH, temperature, and TDS sensors. The collected data are sent to a server and displayed on a web dashboard in real time, equipped with automatic notification features. The proposed system is expected to improve monitoring efficiency and increase the productivity of hydroponic cultivation

Abstrak: Perkembangan teknologi informasi dan komunikasi mendorong transformasi digital dalam berbagai sektor, termasuk pertanian. Salah satu teknologi yang banyak diterapkan adalah Internet of Things (IoT) yang memungkinkan perangkat saling terhubung melalui jaringan internet untuk melakukan pemantauan dan pertukaran data secara real-time. Pada budidaya hidroponik, kestabilan kualitas air menjadi faktor penting yang mempengaruhi pertumbuhan tanaman. Parameter utama yang perlu diperhatikan meliputi tingkat keasaman air (pH), suhu air, serta konsentrasi nutrisi terlarut yang diukur menggunakan Total Dissolved Solids (TDS). Namun, pemantauan kualitas air masih banyak dilakukan secara manual sehingga kurang efisien dan berpotensi menimbulkan keterlambatan dalam mendeteksi perubahan kondisi air. Penelitian ini bertujuan merancang sistem pemantauan kualitas air hidroponik berbasis IoT menggunakan mikrokontroler ESP32 yang terintegrasi dengan sensor pH, suhu, dan TDS. Data dikirim ke server dan ditampilkan pada web dashboard secara real-time serta dilengkapi notifikasi otomatis. Sistem ini diharapkan meningkatkan efisiensi pemantauan dan produktivitas budidaya hidroponik.

The method used is the application of the NN model, especially the Multilayer Perceptron (MLP), which is trained using historical air quality data such as dust particle levels (PM10, PM2.5), carbon monoxide (CO) gas, and temperature. The data used in this study came from urban air quality monitoring stations collected over a period of time. The results show that the Neural Network algorithm can provide quite accurate predictions of air quality with a low Mean Absolute Error (MAE) value, showing the effectiveness of the model in predicting f fluctuations in air quality. The conclusion of this study is that Neural Network algorithms, specifically MLPs, are an effective tool for air quality prediction, which can be used as a basis for urban air quality management policies.
