Abstract

The development of a portable ladder for pepper harvesting in Sanatap Village, Sajingan Besar Sub-district aims to improve farmers' ergonomics, safety, and productivity. Using the Quality Function Rapid Entire Body Assessment (REBA) dan Deployment (QFD) methods, this study identified farmers' key needs such as ease of operation, lightweight materials, and ease of storage. The designed ladder is foldable, has wheels, and is made of strong yet lightweight galvanised iron, and has additional safety features. The results of the analysis showed a significant improvement in the farmers' working posture and a reduction in the risk of injury, from moderate risk (REBA score 4-7) to low risk (REBA score 2-3). This shows that the ladder can reduce the risk of injury to pepper farmers. In addition, this portable ladder is expected to not only improve the efficiency and safety of pepper farmers, but also open new business opportunities that contribute positively to the local economy. The implementation of this tool is expected to improve the welfare of farmers in Sajingan Besar Sub-district and provide practical solutions that are profitable and sustainable.

Abstract

Predictive maintenance involves the early detection of potential machine failures and subsequent maintenance to prevent such failures. Machine learning is a pertinent statistical method for predictive maintenance, enabling the early detection of machine failures and the implementation of preventive measures through a model. The development of the machine learning model commences with data collection from the machine, encompassing vibration, acceleration, machine temperature, and machine sound, facilitated by a microcontroller equipped with sensors. Subsequently, the data undergoes cleaning, including removing outliers or missing values and standardization. Data is partitioned into 70% allocated for training and 30% for testing. After determining hyperparameters and their values through hyperparameter tuning, the training data is utilized to train machine learning models, such as K-nearest neighbor, decision tree, and random forest models. Post-training, the models are evaluated using the remaining test data, employing performance metrics such as accuracy, precision, recall, and F1-score. The random forest model excels due to its utilization of a substantial number of trees for predictions and the full exploitation of the variables which F1-score is 91.22%. The best-performing model is subsequently deployed into a monitoring system, providing real-time machine condition predictions. The deployment results validate the accurate prediction of machine failures.

Abstract

Senior Motor Workshop faced several workplace problems, including disorganized working areas, untidy equipment, low cleanliness levels, and the absence of Standard Operating Procedures (SOPs). This study aims to improve the workplace environment through the implementation of the 5S method (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) and to develop SOPs as guidelines for sustainable implementation. Data were collected through observation, interviews, and documentation, covering workshop conditions, workspace and rack dimensions, layout, as well as the quantity and volume of spare parts. The analysis was conducted using a 5S checklist, assessment of existing conditions, implementation of the 5S method, and evaluation after improvements. The results showed an increase in the score from 18 to 74, indicating a more organized, neat, clean, and disciplined workplace. This improvement was supported by the establishment of SOPs, which include sorting, organizing, cleaning, utilization, and maintenance of workshop equipment.

Abstract

Desa Sengkubang, Kabupaten Mempawah, merupakan wilayah pesisir rawan kebakaran hutan dan banjir yang berdampak pada kestabilan ekonomi rumah tangga dan kerentanan terhadap masalah kesehatan. Program pengabdian ini memiliki pembeda dari PkM sejenis karena mengintegrasikan penguatan rantai nilai produk olahan berbasis komoditas lokal dengan penguatan kapasitas Komunikasi, Informasi, dan Edukasi (KIE) kesehatan dalam satu desain intervensi terpadu, melibatkan dua mitra dengan peran berbeda: kelompok PEKKA dan PKK. Mitra PEKKA menghadapi kendala pada konsistensi produksi, mutu, dan pemasaran, sedangkan mitra PKK mengalami keterbatasan manajemen kegiatan serta kemampuan menyusun dan menyampaikan KIE kesehatan yang terstruktur.Kegiatan bertujuan meningkatkan (1) kapasitas manajemen produksi, standardisasi mutu, dan pemasaran produk olahan komoditas perkebunan pada PEKKA serta (2) kapasitas manajemen program dan keterampilan penyusunan–penyampaian KIE kesehatan pada PKK, sebagai fondasi transformasi ekonomi dan penguatan promosi kesehatan di wilayah rawan bencana. Metode dilaksanakan Agustus–Oktober 2025 melalui pendekatan pelatihan-partisipatif dan pendampingan: pemetaan kebutuhan, pelatihan manajemen produksi–pemasaran, penerapan teknologi tepat guna untuk memperbaiki efisiensi proses dan mutu, serta penguatan perencanaan KIE (pesan, media, dan simulasi penyampaian) yang diintegrasikan dengan agenda desa. Evaluasi menggunakan pretest–posttest pengetahuan, penilaian keterampilan berbasis observasi (checklist proses produksi dan praktik KIE), serta pemantauan luaran produksi dan implementasi kegiatan. Sebanyak 20 peserta aktif mengikuti program. Hasil menunjukkan peningkatan skor pengetahuan sebesar  71,4% berdasarkan perbandingan nilai pretest–posttest pada materi produksi–pemasaran dan KIE kesehatan, disertai peningkatan keterampilan pengolahan (termasuk minyak kelapa dan VCO), perbaikan mutu proses (kebersihan dan pengemasan), peningkatan kapasitas produksi, serta tersusunnya perangkat KIE dan pelaksanaan simulasi/penyuluhan oleh PKK. Keberlanjutan diperkuat melalui kolaborasi dengan pemerintah desa untuk integrasi agenda dan dukungan jejaring.

Abstract

Kegiatan Pengabdian kepada Masyarakat (PKM) ini dilaksanakan untuk mengatasi permasalahan pemanfaatan limbah sabut kelapa yang selama ini belum dikelola secara optimal oleh Kelompok Pelestari Lingkungan Buih Muara di Desa Sungai Kupah, Kabupaten Kubu Raya. Limbah sabut kelapa yang jumlahnya mencapai 26.000–39.000 kg setiap musim panen umumnya hanya dibakar atau dibiarkan membusuk sehingga berpotensi menimbulkan dampak lingkungan. Program PKM ini menerapkan teknologi tepat guna berupa hot moulding press untuk mengolah serat sabut kelapa menjadi produk bernilai tambah berupa piring sekali pakai. Metode pelaksanaan menggunakan pendekatan partisipatif melalui tahapan identifikasi masalah, perancangan alat, diseminasi teknologi, pelatihan operasional, dan evaluasi. Hasil kegiatan menunjukkan bahwa alat hot moulding press mampu meningkatkan pemanfaatan limbah sabut kelapa dan menghasilkan 10–12 piring per siklus pencetakan dengan suhu 150 °C. Selain itu, kegiatan ini membuka peluang usaha baru, meningkatkan pengetahuan teknis mitra, serta memberikan dampak sosial bagi masyarakat dan mahasiswa melalui kolaborasi dalam kerangka Merdeka Belajar Kampus Merdeka (MBKM). Program ini berkontribusi pada peningkatan perekonomian masyarakat Desa Sungai Kupah melalui diversifikasi produk berbahan limbah tanaman kelapa serta penerapan teknologi ramah lingkungan.
