Abstract

Ngrangin Hamnlet, Sumberpasir Village, Malang Regency, is a major banana growing area that produces a lot of organic waste from banana stems. Sadly, this waste is not being used as well as it could be, even though there is a growing need for fertilizer, which is often hard to get for farming. The Purpose of this community service is to help banana farmers learn how to make compost from banana plant waste. This will help them become more self-sufficient effective in getting organic fertilizer locally. This workshop used a learning and hands on approach, including advice, practice and technical help. The activity was aimed at 26 banana farmers who belong to farmer group in Ngrangin Hamlet. The result show that the farmer understood more about recycling farm waste and had better skills in making compost. The compost was good quality, with a crumby texture, dark brown colour, and odorless. Another good thing was that banana farmer started working together to manage compost in the hamlet and they became more aware of sustainable farming methods. This activity shows that helping people locally with the right technology can be a good way to manage waste and provide the fertilizer farmers need.

Abstract

The Sukun, Lowokwaru, and Karangbesuki areas of Malang City are known for their supply of construction workers, the most significant proportion being carpenters. However, the transformation of modern construction materials, such as light steel, aluminum, and WPC, is gradually replacing the role of wood in structural work. This has reduced the scope of work for pre-construction carpenters, so a solution is needed to maintain the sustainability of their profession through post-construction work. This community service program is designed in response to this challenge through training in making smart furniture: functional, compact, and modern furniture relevant to the limited space needs of student boarding/rental housing around the State University of Malang campus. The activity methods include concept counseling, introduction to technical design (DED), and direct manufacturing practice in two partner workshops, namely the Revan Furniture and Indah Meubel wood workshops, each making smart furniture using different material variants (solid wood, Dutch teak, multiplex, and HPL finishing). The main work is a folding table and chair unit with dimensions of 120x100x90 cm that can be easily folded for minimalist housing needs. Evaluation of the training and outreach results showed a 45% increase in understanding of working drawings, a 20% increase in jointing skills, and a 20% increase in OSH awareness. This product meets three key criteria for engineered furniture: functionality, ease of use, visual appeal, and comfort. In conclusion, this training enhanced the carpenters' technical capacity and opened up new economic opportunities in the adaptive furniture sector..ABSTRAKWilayah Sukun, Lowokwaru, dan Karangbesuki di Kota Malang dikenal sebagai penyedia pekerja konstruksi, proporsi terbanyak adalah tukang kayu. Namun, transformasi material konstruksi modern seperti penggunaan baja ringan, aluminium, dan WPC, secara bertahap menggantikan peran kayu dalam pekerjaan struktur. Hal ini berdampak pada berkurangnya ruang lingkup kerja tukang kayu pra-konstruksi, sehingga diperlukan solusi untuk mempertahankan keberlangsungan profesi mereka melalui pekerjaan pasca-konstruksi. Program pengabdian ini dirancang sebagai respon atas tantangan tersebut melalui pelatihan pembuatan smart furniture: furnitur fungsional, ringkas, dan modern yang relevan dengan kebutuhan ruang terbatas pada hunian kost/kontrak mahasiswa di sekitar kampus Universitas Negeri Malang. Metode kegiatan meliputi penyuluhan konsep, pengenalan desain teknis (DED), hingga praktik pembuatan langsung di dua bengkel mitra, yaitu bengkel kayu Revan Furnitur dan Indah Meubel, pembuatan smart furniture masing-masing menggunakan varian material berbeda (solid wood, jati belanda, multiplek, dan finishing HPL). Karya utama berupa unit meja-kursi lipat berdimensi 120×100×90 cm yang dapat dilipat secara mudah untuk kebutuhan hunian minimalis. Evaluasi hasil pelatihan dan penyuluhan menunjukkan peningkatan pemahaman gambar kerja sebesar 45%, keterampilan kerja sambungan sebesar 20%, dan kesadaran K3 naik sebesar 20%. Produk ini memenuhi tiga dari empat kriteria utama furnitur teknik: fungsionalitas, kemudahan penggunaan, daya tarik visual, dan kekurangan adalah kenyamanan. Kesimpulannya, pelatihan ini meningkatkan kapasitas teknis tukang kayu, dan  membuka peluang ekonomi baru dalam sektor furnitur adaptif.

Abstract

In the landslide–prone terrains of Puri District, East Java, engineers have crafted a groundbreaking solution to a life–threatening problem: a hybrid retaining wall that fuses traditional batu kali masonry with reinforced concrete, designed to outlast both relentless soil creep and violent earthquakes. Standing 4.25 meters tall and stretching 20 meters across a fragile slope, this structure—embedded 1.5 meters into the earth—defies seismic forces amplified by climate change, withstanding horizontal accelerations of 0.19g and shear forces that spike 388% during quakes. Rigorous analysis reveals its secret: D16 steel bars, spaced as tight as 100 mm at stress hotspots, work in concert with locally quarried stone to balance cost and resilience. The wall’s success lies in numbers—sliding safety factors of 4.02 (normal) and 1.78 (seismic), bearing pressures grazing 99.9% of limits without failure—but its true victory is human. Shielding a riverside community from catastrophic landslides, it ensures roads stay open, homes remain intact, and daily life flows uninterrupted. As Indonesia battles rising rainfall and tectonic unrest, this innovation offers a replicable blueprint: marrying ancestral building wisdom with 21st–century engineering to turn vulnerability into durability. Keywords: Retaining Wall; Seismic Condition; Landslide Mitigation; Masonry Structure; Sustainable Infrastructure.

Abstract

Building materials that emit pollutants, are non-renewable, and generate environmental waste require attention. Wood, a popular and natural material, is facing increasing scarcity, necessitating a substitute. Laminated bamboo emerges as the most akin and natural alternative to wood. Research into laminated bamboo encompasses diverse cross-sections, joint types, and field applications, demanding further investigation.This study aimed to ascertain failure types and damage patterns in laminated bamboo hollow section beam-column joints modified with glue-in rod-bracket connections, using petung bamboo (dendrocalamus asper). The research employed an experimental approach with descriptive analysis. Joint failures were evaluated based on moment-rotation relationships within prescribed rotational limits per standards, while joint damage was assessed through visual inspection of joint components.The study's dependent variables included thread rod diameters of 6 mm, 8 mm, dan 10 mm, and 4 dan 6 embedded thread rods, while the independent variables were failure types and joint collapses. Results revealed serviceability failures in samples 8.6, 10.4, and 10.6. Joint damage across all test specimens primarily manifested as broken thread rods. The highest joint strength observed was 6.28 kNm in sample 10.6, with the lowest at 2.25 kNm in sample 6.4.Based on the findings, increasing thread rod diameters to achieve ductile joints resulted in longer rotations but did not meet the planned strength due to bracket-induced prying effects causing bolt head failure. Despite this, the collapse type aligned with the research plan. Addressing the bracket's fulcrum effect during field applications requires solutions, potentially involving enlarging the bracket's base and increasing the number of thread rod points. The tests did not damage the laminated bamboo components, emphasizing the need to consider laminated bamboo cross-sectional dimensions and thread rod fulcrum effects in subsequent tests to ensure uniform component performance.

Abstract

Transformasi digital dalam industri konstruksi menuntut peningkatan efisiensi dan akurasi, terutama dalam pengelolaan material seperti besi tulangan yang memiliki kontribusi besar terhadap struktur dan biaya proyek. Building Information Modelling (BIM) hadir sebagai solusi inovatif untuk menjawab tantangan ini. Namun, adopsi BIM dalam proyek skala kecil-menengah, khususnya di daerah seperti Tulungagung, masih sangat terbatas. Kegiatan pengabdian ini bertujuan untuk mensosialisasikan dan melatih penggunaan teknologi BIM kepada pelaku konstruksi lokal, dengan fokus pada perencanaan kebutuhan tulangan besi untuk membangun kolom dan balok. Pelatihan ini melibatkan pemodelan struktur 3D menggunakan Autodesk Revit serta penerapan metode Bar Bending Schedule (BBS) untuk menghitung volume, waktu, dan efisiensi material. Hasil ini BIM mampu mengurangi potensi pemborosan besi tulangan sebesar 18,7% dan memangkas perkiraan waktu dari 9 jam menjadi 3 jam. Selain peningkatan akurasi perencanaan, peserta menunjukkan antusiasme yang tinggi untuk menerapkan BIM dalam proyeknya. Temuan ini membuktikan bahwa pelatihan BIM berbasis studi kasus lokal efektif dalam meningkatkan efisiensi proyek dan kapasitas sumber daya manusia di wilayah tersebut. Replikasi kegiatan dan dukungan infrastruktur digital direkomendasikan untuk memperluas dampak positif teknologi BIM di sektor konstruksi nasional. Kegiatan ini berdampak positif dalam membangun kesadaran akan pentingnya digitalisasi perencanaan konstruksi dan membuka peluang untuk adopsi BIM yang lebih luas di tingkat lokal. Disarankan agar ada dukungan lebih lanjut berupa pelatihan tingkat menengah dan penyediaan akses perangkat lunak BIM sehingga dampak dari kegiatan tersebut dapat berkelanjutan.
