Abstract

Santan kelapa adalah komoditas pertanian serbaguna, terutama sebagai bahan makanan dalam hidangan dan minuman, dengan nilai ekonomi yang tinggi. Berbagai desain mesin telah dikembangkan untuk mendukung industri pengolahan santan. Salah satu metode tersebut adalah ekstraksi mekanis menggunakan proses pengepresan. Makalah ini menyajikan desain dan pengembangan alat ekstraktor santan kelapa portabel dengan sistem ulir horizontal. Setelah desain selesai, dilakukan pengujian kinerja dan evaluasi ekonomi, yang menunjukkan kapasitas rata-rata sebesar 11,3 kg/jam dan titik impas (BEP) sebesar 2.925,57 kg/tahun. Mesin ini juga mencapai hasil rendemen hingga 76%. Pengujian kinerja lebih lanjut menunjukkan bahwa suhu air secara signifikan memengaruhi proses ekstraksi sebagai katalis. Secara khusus, penggunaan air mendekati titik didih menghasilkan hasil optimal. Mesin portabel ini ditujukan untuk memenuhi kebutuhan teknologi usaha mikro dan kecil dalam pengolahan santan kelapa.

Abstract

Corn (Zea mays) is a vital global commodity, yet traditional shelling remains a bottleneck for small-scale farmers, leading to high labor intensity and low productivity. This study aimed to design, construct, and evaluate the performance of a spiral-type corn sheller powered by a 1-HP electric motor. The performance was assessed through quantitative parameters (feeding rate, shelling capacity, and yield) and qualitative parameters (percentage of damaged and unshelled seeds). Results indicated a shelling capacity of 150 kg/h with a yield of 87%. The quantitative analysis showed 0.24% of unshelled seeds and 7% seed damage. Economic evaluation revealed a production cost of Rp 135.83/kg and a Break-Even Point (BEP) of 1,911.96 kg/year. The spiral-type mechanism effectively increases efficiency compared to manual shelling (±20 kg/h), making it a viable solution for small-scale agricultural industries.

Abstract

The post-harvest processing of areca nut (Areca catechu L.) in Fifty Thousand Kota District, which has a plantation area of 1,254 ha with a production of 196.12 tons/year, is often done manually, especially at the stage of slicing young areca nuts into thin slices. The manual method using knives or cutters is time-consuming (8 minutes/kg) and carries a high risk of cuts. However, sliced areca nuts have a higher selling price and low water content (0.9%), which increases farmers' sales by up to 45% compared to whole nuts. Therefore, this community service activity (PkM) aims to overcome these problems through training and demonstrations on the use of young areca nut slicing machines to 15 participants from farmer groups at the FRD Pinang Raya SME, Mungo, Limapuluhkota Regency. The methods used include coordination, needs assessment, machine testing, and participatory practical training. The results of the activity showed that this training successfully improved the participants' understanding and skills in operating and maintaining the machine. This technology transfer has been proven to increase time efficiency and productivity, producing faster and more uniform pineapple slices compared to the manual method. Overall, this PkM has succeeded in empowering the community through practical solutions to post-harvest processing problems, contributing to increased processing efficiency and the potential for economic improvement for partners.

Abstract

The juvenile correctional system (LPKA) in Indonesia carries out a fundamental mandate to rehabilitate correctional students (Andikpas) and prevent the recurrence of criminal acts (recidivism). A crucial instrument in correctional rehabilitation is competency-based vocational training. This study aims to analyze the theoretical relevance of the Shielded Metal Arc Welding (SMAW) welding training program based on the Indonesian National Work Competency Standard (SKKNI) at LPKA, identify existing structural implementation challenges, and formulate optimization strategies through a collaborative model. The results of the analysis show that welding training is a very effective strategic program. The industrial sector in Indonesia needs at least 45,000 welding experts, proving the high demand for the job market. These skills serve as a powerful catalyst to achieve desistance by providing the human capital needed to get a stable job, thus overcoming the job instability associated with the risk of repeat crime. Despite having great potential, the implementation of coaching programs at LPKA is hampered by limited funds, inadequate facilities, and a lack of expert instructor Human Resources (HR). To overcome this obstacle, it is recommended to adopt a Mutualistic Partnership model with external parties, which aims to ensure the standardization of the 320 Hours of Training (JP) curriculum in accordance with SKKNI, competency certification, and integration of vocational work readiness measurements. This partnership creates mutual benefits and strengthens LPKA's capacity on an ongoing basis.

Abstract

Proses pengeringan ikan merupakan proses dalam menjaga mutu ikan sehingga dapat disimpan dalam waktu yang lama, sehingga aman dikonsumsi oleh konsumen. Tujuan penelitian ini adalah mengetahui pengaruh suhu dan laju kecepatan udara pengering terhadap ikan nila yang dikeringkan, melakukan uji kinerja alat, serta melakukan uji organoleptik ikan nila kering. Metode yang digunakan dalam penelitian ini meliputi modifikasi alat, persiapan bahan, pengujian kinerja, dan uji organoleptik ikan kering. Peralatan yang digunakan terdiri atas ruang pengering, rak pengering, exhaust fan, termokopel tipe K, Arduino Uno, data logger, anemometer, ruang pemanas, dan kompor listrik 2000 W. Pada penelitian ini suhu pada setiap rak berbeda berdasarkan data yang diperoleh. Suhu pengeringan berfluktuasi dari 42 °C hingga 71 °C selama 7 jam proses pengeringan. Pengurangan jumlah air pada jam pertama berkisar antara 26–40 gram/jam, sedangkan pada jam kedua sebesar 10–15 gram/jam dan menurun secara bertahap pada jam berikutnya. Semakin lama proses pengeringan berlangsung, semakin sedikit jumlah air yang diuapkan. Laju kecepatan aliran udara dalam ruang pengering tergolong tinggi, yaitu 3–3,6 m/s. Kadar air akhir ikan adalah 15,14%, sehingga produk ikan nila kering telah memenuhi standar SNI, termasuk kategori ikan kering berkualitas baik dan memiliki daya simpan lebih lama. Laju pengurangan air pada ikan berada pada kisaran 9,85–11,85 gram air/jam. Total energi pengeringan adalah 0,9278 kWh dengan efisiensi energi pengeringan sebesar 46,4%. Berdasarkan uji organoleptik, ikan nila kering memiliki warna cerah serta tekstur dan aroma yang baik.
