Abstract

Value engineering is a decision-making process based systematic and structured multi disclipinary. Drainage is a disposal water mass media in natural or artificial from the surface or subsurface of a place. In the housing scope, drainage is enabled to accomodate the flow of used water and rain water from the house which then flowed into the downstream or river as the final disposal place. The purpose of this study is to assess the initial design of the stream viewed from the cost budget plan. Find out whether the alternative design are required, find out the ideal alternative design, and get a comparison between the initial design and the alternative design. The result of this research is the analysis of budget plan, the production cost of initial design with u-ditch and buis concrete material is inefficient with budget of cost Rp. 1.781.350.200,- and then made alternative design buis concrete precast with budget of cost Rp. 1.104.667.700,- . After comparison between initial design and some alternative design, it is known that alternative design that can be recomended to be done is the alternative design with buis concrete precast material because it has lower price, by the difference of profit Rp. 676.672.500,-.

Abstract

Proses penyaringan tahu di IKM Tahu ECO masih dilakukan secara manual sehingga membutuhkan tenaga fisik besar, memakan waktu, dan berpotensi menimbulkan risiko ergonomi serta inkonsistensi mutu. Penelitian ini bertujuan merancang alat penyaring tahu otomatis yang lebih efisien, ergonomis, aman, dan higienis dengan menggunakan pendekatan metode Research and Development (R&D) serta mempertimbangkan aspek Product Design & Development (PDD). Pengumpulan data dilakukan melalui observasi proses produksi, pengukuran antropometri operator, serta analisis kebutuhan teknis dan sanitasi. Hasil perancangan menghasilkan alat dengan struktur ergonomis setinggi 100 cm, sistem mekanis berbasis motor listrik dan transmisi pulley–V-belt, serta saringan stainless steel food grade. Analisis ekonomi menunjukkan total biaya produksi sebesar Rp 2.350.000 dengan harga jual Rp 2.920.000 dan margin keuntungan 20%, sehingga alat dinyatakan layak secara ekonomis. Dari aspek keselamatan, alat telah dilengkapi panel listrik terisolasi, manajemen kabel, pelindung mesin, serta material yang higienis. Pengujian menunjukkan bahwa alat mampu mempercepat proses penyaringan, meningkatkan efisiensi tenaga kerja, dan menghasilkan kualitas sari kedelai yang lebih konsisten dibanding metode manual. Secara keseluruhan, alat penyaring tahu otomatis ini dinilai efektif untuk meningkatkan produktivitas IKM, memperbaiki ergonomi kerja, serta memenuhi standar keamanan pangan.
