Abstract

Tempe merupakan makanan tradisional berbasis kedelai yang memiliki peran penting dalam pemenuhan kebutuhan gizi dan konsumsi harian masyarakat Indonesia. Namun, proses fermentasi tempe yang masih dilakukan secara konvensional sering menghadapi kendala terkait ketidakstabilan suhu dan kelembapan selama proses pengolahan, sehingga berpotensi menghasilkan produk cacat yang tidak layak konsumsi. Kondisi ini mendorong terjadinya peningkatan Food Lost and Waste (FLW), yang tidak hanya merugikan pelaku usaha dari sisi ekonomi, tetapi juga dapat menurunkan kapasitas produksi dan memberikan dampak negatif terhadap aspek keberlanjutan lingkungan. Oleh sebab itu, diperlukan inovasi teknologi yang mampu mengendalikan parameter fermentasi secara optimal dan konsisten selama proses berlangsung. Penelitian ini bertujuan untuk mengurangi tingkat produk cacat tempe dan meminimalkan FLW melalui perancangan dan implementasi alat fermentasi berbasis Internet Of Things (IoT). Metodologi penelitian meliputi observasi langsung terhadap proses produksi tempe, penyusunan Value Stream Mapping (VSM) As-Is untuk menganalisis aliran proses dan mengidentifikasi pemborosan, perancangan prototipe alat IoT, pengujian eksperimen pada tiga variasi kondisi fermentasi (ruang terbuka, ruang tertutup, dan inkubator IoT), serta penyusunan VSM To-Be untuk mengukur peningkatan efisiensi proses setelah penerapan alat. Hasil implementasi IoT mampu menjaga kelmabapan dan suhu 30℃-40℃ secara otomatis dan mampu mempersingkat waktu fermntasi yang semula 55 jam menjadi 26 jam

Abstract

The increasingly advanced digital era and the development of technology and information through WhatsApp Groups (WAG) currently provide convenience in communicating and quickly obtaining information, but at the same time also quickly in the misuse of information dissemination. Therefore, this wise educational activity in the use of technology and information through WhatsApp Groups (WAG) aims to increase digital literacy and awareness of healthy social media for members of the Embung Kandong Village Youth Organization. The methods used include delivering materials, interactive discussions, and providing case examples related to digital ethics, data security, and preventing the spread of false information. The results of the activity show that members of the Youth Organization have increased their understanding of the responsible use of social media, including the ability to sort information, maintain privacy, and communicate ethically in the digital space. Education through WAG has proven effective as a flexible, easily accessible learning tool and is able to encourage active participation of participants. Thus, this activity contributes to forming wiser and more productive digital behavior among village youth so that they are wiser in using social media.

Abstract

Height measurement is an important activity in community health services, particularly for growth monitoring and anthropometric data collection. However, manual height measurement processes often face challenges such as time inefficiency, potential reading errors, and inconsistent measurement results. This community service activity aims to implement an automatic height measurement device based on Arduino Uno and an ultrasonic sensor as a simple technological solution to support community health service activities during the Community Service Program (PENGABDIAN KEPADA MASYARAKAT) in Pringgasela Selatan Village. The implementation method includes device design, system assembly, functional testing, and direct application of the device in community service activities. The results show that the automatic height measurement device provides relatively consistent measurement results compared to manual methods and simplifies the measurement process by delivering quick and easily readable outputs. The application of this device also improves the efficiency of health service activities and supports the provision of more practical measurement data. Therefore, the Arduino-based automatic height measurement device can be utilized as a supporting tool for community health services using simple technology.

Abstract

This community service program aims to enhance the skills, creativity, and economic potential of women members of the PKK group in Kembangsari Village through a training session on leaf-based ecoprint techniques using cotton fabric. The activity was conducted in a single mentoring session involving 30 participants. The implementation method consisted of delivering fundamental material on ecoprint principles, demonstrating the pounding technique, facilitating hands-on practice, and evaluating both the participants’ artworks and their attitudinal changes before and after the training. Throughout the activity, participants were able to understand each production stage ranging from leaf selection, motif arrangement, and pounding, to the color-fixation process. The resulting ecoprint works showed good visual quality, although several participants required additional time to determine more harmonious motif compositions. In terms of affective outcomes, there was a noticeable increase in motivation and self-confidence: 20 participants expressed their intention to continue practicing ecoprint at home, and 12 participants identified ecoprint as a potential source of additional income. Challenges encountered during the program included inconsistent leaf pigment quality, variations in leaf conditions, and limited time that prevented exploration of other ecoprint techniques such as bundling and tataki-zome. However, these challenges were relatively minor and provided opportunities for further capacity-building activities. Overall, this program successfully improved participants’ knowledge and practical skills, while also pening prospects for the establishment of an ecoprint craft group as a creative local product identity of Kembangsari.

Abstract

Limbah rumah tangga organik di Kabupaten Lombok Timur, khususnya Desa Terara, masih menjadi persoalan lingkungan yang belum tertangani dengan baik. Di lokasi ini limbah rumah tangga ditangani melalui pembakaran atau pembuangan sembarangan yang berpotensi mencemari lingkungan. Kegiatan pengabdian ini bertujuan memberdayakan Kelompok Wanita Tani (KWT) Sinar Mulia melalui produksi eco-enzyme sebagai pupuk organik cair berkelanjutan. Metode pelaksanaan yang digunakan mencakup sosialisasi, demonstrasi, praktik langsung, evaluasi, dan monitoring. Selain itu telah  dilakukan studi pendahuluan untuk mengidentifikasi permasalahan, dilanjutkan dengan uji coba pembuatan eco-enzyme dari sampah dapur organik (kulit buah dan sayuran) yang difermentasi dengan gula merah dan air. Peserta kemudian dilibatkan dalam praktik langsung agar mampu memproduksi eco-enzyme secara mandiri. Evaluasi dilakukan melalui kuesioner dan diskusi, sementara monitoring fermentasi dilakukan untuk menilai kualitas produk yang dihasilkan. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan anggota KWT dalam mengolah limbah rumah tangga menjadi pupuk organik cair dengan rata-rata sebesar 90%. Produk eco-enzyme yang dihasilkan memiliki kualitas fisik baik dan terbukti meningkatkan pertumbuhan tanaman sayuran hingga 37% dibanding kontrol. Program ini tidak hanya mengurangi volume sampah rumah tangga dan menekan pencemaran lingkungan, tetapi juga memperkuat kemandirian petani, mendukung praktik pertanian organik, serta membuka peluang ekonomi melalui pengembangan produk unggulan desa.

Abstract

Soybeans are one of the largest food commodities in Indonesia. Tempe is a soybean product that is a daily staple in Indonesian cuisine. Tempe is a traditional food with high nutritional value, and it is consumed by almost all ages. A common problem is that tempeh doesn't last long after being purchased at the market. Poor quality tempeh affects its taste when consumed. Poor quality tempeh is usually caused by unpredictable weather during the fermentation process and a short storage period. This can increase food loss and waste (FLW). FLW itself is the loss and waste of food, making FLW monitoring crucial for improving food security and mitigating climate change. By measuring and monitoring temperature and humidity parameters in real time, the system integrates IoT technology, such as the DHT11 sensor, to measure temperature and humidity, ensuring that the tempe fermentation process is maintained at a stable temperature and runs optimally.Furthermore, because it is IoT-based, the temperature on this device can be monitored in real time via a smartphone, provided it is connected to the internet. In the monitoring application there is an interface that displays the temperature and humidity at that time and there is a bottom for turning the lights and fans on or off manually.
