Abstract

Gudang berperan sebagai distributor untuk menyalurkan bahan baku menuju jalur produksi. Respon gudang dalam menyuplai bahan baku berkaitan dengan proses penyiapan yang mempengaruhi waktu setup komponen bahan baku untuk dikirim ke lini perakitan. Jumlah produksi dari lini perakitan yang bertambah dari 160 unit menjadi 200 unit per bulan menuntut waktu setup yang lebih pendek dari pihak gudang bahan baku. Selama ini waktu set-up yang diperlukan untuk 1 lot produksi atau 40 unit produk adalah berkisar antara 5 – 7 hari. Dalam penelitian ini dilakukan pengaturan ulang tata letak dan perbaikan terhadap prosedur setup di gudang bahan baku untuk mengurangi waktu penyiapan komponen rakitan sebelum masuk ke jalur produksi. Hasil dari pengaturan ulang tata letak dan perbaikan prosedur ini adalah penghematan ruang sebesar 5 %, eliminasi aktivitas setup yang tidak perlu yang menghasilkan waktu setup yang lebih pendek, dan  prosedur baru penyiapan komponen yang lebih efisien. Kata kunci: gudang bahan baku, proses penyiapan, tata letak, waktu setup.     Abstract   Storage have a function to distribute materials to production line. Storages respon in time supplying materials influenced by preparation process  known as component setup  process. Increased production quantity in production line from 160 units to 200 units per month press for shorter storages setup time. All this time setup time for one production lot or 40 units range from five to seven days. This research try to improve setup prosedur to reduce component preparation time before entered production line. Research include redesign of storage layout. The results show improvement by 5 percent saving in space, elimination of unnecessary preparation activity resulting in shorter setup time, and the new preparation procedure  that more efficient. Key word: layout, materials storage, preparation process, setup time.

Abstract

Astuti et al, 2018. Utilization of Organic Waste in the Making of Bacillus thuringiensis-based Bioinsecticides as Agents for Control of Caisim Brassica juncea Pests. JLSO 7(2):136-143. Bacillus thuringiensis was one of the entomopathogenic bacteria that can produces toxic crystal proteine (ᴕ-endotoksin). The use of bioinsecticide as a biological agent in pest control was one component of integrated pest control (IPM). The aimed of this reseacrh was to know the population of pests in plants and the percentage of damage to plants that exist in each treatment. The research was conducted in a vegetable garden in the Banyuasin district in November 2017 until January 2018. The research method used a randomized block design with 5 treatments and 4 blocks. The treatment was Bacillus thuringiensis KJ3R5 cultured in coconut water and rice washing water  (A), Bacillus thuringiensis LC2 cultured in coconut water and tofu wastewater (B), commercial Bacillus thuringiensis (C), inorganic insecticide (sidametrin) (D), and water as control (E). The variables observed were arthropod populations on the canopy and ground surface of choy sum (Brassica rapa var. parachinensis or Brassica chinensis var. parachinensis) plants. The results showed that 4 species of pests i.e. Pyllotreta crucifera, Spodoptera litura, Plutella xylostella, and Helula sp. Treatment with Bacillus thuringiensis LC2 (B) resulted in reduction of plant damage by 61%.
