Abstract

Kegiatan ini bertujuan untuk menganalisis peningkatan pengetahuan anggota pertanian Agrowisata Barrotani terkait adopsi teknologi budidaya melon menggunakan sistem screenhouse terintegrasi Pembangkit Listrik Tenaga Surya (PLTS) dan irigasi tetes. Metode pelaksanaan melibatkan pretes dan postes untuk mengukur tingkat pengetahuan sebelum dan sesudah intervensi berupa penyuluhan dan demonstrasi intensif. Data dianalisis menggunakan metode Normalized Gain (N-Gain) untuk mengukur efektivitas transfer ilmu, baik secara keseluruhan maupun secara komparatif berdasarkan kelompok usia (< 35 tahun dan > 35 tahun) serta per topik. Hasil menunjukkan bahwa transfer ilmu berhasil meningkatkan pengetahuan secara substansial, dengan rata-rata N-Gain keseluruhan adalah 0.584, yang berada dalam klasifikasi Sedang. Peningkatan tertinggi tercatat pada topik Screenhouse (g=0.640). Selain itu, peningkatan terjadi secara merata dan inklusif; baik Kelompok Muda (g=0.623) maupun Kelompok Dewasa (g=0.551) sama-sama berada dalam kategori Sedang. Kesimpulan menunjukkan bahwa program ini efektif dan berhasil mengatasi potensi disparitas usia, memberikan dampak positif signifikan pada literasi teknologi, meskipun intervensi lanjutan sangat direkomendasikan untuk memaksimalkan penguasaan aspek teknis seperti PLTS.

Abstract

This study presents the design, fabrication, and evaluation of a space-efficient, lightweight, and foldable study table intended to enhance learning conditions in Islamic boarding school (pesantren) environments. The table was designed using Computer-Aided Design (CAD) software with a focus on ergonomic principles, particularly a recommended working height of 70 cm to support proper posture. The final product features a durable steel tube frame, a plywood tabletop, and a collapsible leg mechanism, enabling compact storage in limited dormitory spaces. The fabrication process included precision cutting, Shielded Metal Arc Welding (SMAW), and the application of rust-resistant enamel paint, resulting in a total weight of approximately 6.5 kg with a load capacity of 40 kg.To evaluate its effectiveness, five students participated in comparative study sessions using both the old and the new table under controlled conditions. Concentration duration, used as the primary performance indicator, increased from an average of 264 seconds with the old table to 359 seconds with the new one—an improvement of 95 seconds or 36.43%. This enhancement is attributed to improved ergonomic posture, structural stability, and positive psychological effects stemming from user involvement and aesthetic design. The foldable design also allows better space utilization in multifunctional boarding school rooms. Overall, the table demonstrates significant functional and educational benefits and offers a scalable, low-cost solution for learning environments in resource-constrained settings. Future improvements may include using lighter materials and integrating storage or seating features to further improve user experience and usability.

Abstract

Ballistic composites are key materials in protective applications designed to absorb and dissipate the impact energy of projectiles. Currently, the reliance on synthetic materials such as aramid fibers (Kevlar) and ultra-high molecular weight polyethylene (UHMWPE) faces challenges including high production costs, environmental impact, and import dependency. Indonesia, with its abundant natural fiber resources such as ramie, abaca, bamboo, and sisal, has great potential to develop sustainable and self-reliant ballistic composite materials. This review aims to systematically examine the potential of Indonesian natural fibers as ballistic composite materials by analyzing their mechanical properties, comparing them with ballistic requirements, and identifying key challenges and development strategies. The study concludes that although natural fibers exhibit promising mechanical properties, they face major limitations such as hydrophilic nature and variability in characteristics. However, chemical treatments and surface engineering (such as reinforcement with SiO₂, CNT, or SiC) have been shown to improve fiber–matrix interfacial performance, thereby opening opportunities for the utilization of Indonesian natural fibers in effective and environmentally friendly ballistic composites.
Peningkatan Produktivitas Melon dan UKM Jamu Melalui Penerapan Teknologi Screen House dan Mesin Pengering di Desa Kepatihan, Kecamatan Selogiri, Wonogiri Nurhayati, Dewi Ratna; Harjunowibowo, Dewanto; Diharjo, Kuncoro; Khasanah, Lia Umi; Supeni, Siti; Solikhah, Efi Nikmatu; Sawitri, Andini Desi

Abstract

Desa Kepatihan, Kecamatan Selogiri, Kabupaten Wonogiri merupakan wilayah agraris dengan potensi hortikultura dan tanaman obat yang cukup besar, namun belum didukung oleh teknologi produksi yang memadai. Dua mitra utama dalam program ini, yaitu Kelompok Tani Barro Tani Manunggal dan UKM Jamu Tanaman Obat Fit (Tanofit), menghadapi kendala produktivitas dan efisiensi usaha. Petani melon masih menggunakan sistem budidaya terbuka yang rentan terhadap iklim, hama, serta boros air. Sementara itu, UKM jamu masih mengandalkan pengeringan tradisional yang tidak higienis, belum memiliki legalitas PIRT, dan minim pemasaran digital. Program ini menawarkan solusi berupa penerapan teknologi screen house berbasis Internet of Things (IoT), sistem irigasi tetes otomatis, dan panel surya untuk mendukung pertanian hemat energi. Bagi UKM, diperkenalkan mini plant jamu skala rumah tangga dengan mesin pengering otomatis berbasis thermostat digital, alat pencuci dan perajang rempah, serta sistem pengemasan higienis. Metode pelaksanaan meliputi pelatihan, instalasi teknologi, pendampingan intensif, serta monitoring dan evaluasi. Hasil program menunjukkan peningkatan produktivitas, efisiensi air, percepatan proses produksi jamu, serta peningkatan kapasitas masyarakat dalam manajemen usaha dan pemasaran digital. Program ini diharapkan menjadi model teknologi tepat guna berbasis energi terbarukan dalam pemberdayaan masyarakat desa.panjang
