Abstract

"Mi Lethek" industry is an industry that produce dry noodles. In the production process of "Mi Lethek" industry, there were some waste that could inflict a financial loss for industry. Waste that occur in "Mi Lethek" industry were unnecessary = inventory and excessive transportation. To reduce that waste, lean manufacturing approach is required. Lean approach functionalized as a system for identified all of activities in "Mi Lethek" industry. That activities were classified into two kind activities, namely value added activity and non value added activity. The time of each activity used to calculate the process cycle efficiency (PCE). Based on the research, the existing score of PCE in "Mi Lethek" industry was 12,05%. The recommendations for increase PCE are relayouting the plant and change the order scheduling of raw materials. These recommendations could increase PCE score  to 15,68 %.ABSTRAKIndustri “Mi Lethek” merupakan industri yang menghasilkan produk berupa mi kering berbahan baku tepung tapioka. Pada proses pengolahan mi di industri “Mi Lethek”, terdapat berbagai pemborosan (waste) yang dapat merugikan industri. Diantara pemborosan yang terjadi berupa persediaan bahan baku yang belum diperlukan dan transportasi berlebih. Untuk mereduksi pemborosan tersebut diperlukan suatu perbaikan pada value stream  menggunakan pendekatan lean. Pendekatan lean difungsikan sebagai sebuah sistem yang digunakan untuk mengidentifikasi seluruh aktivitas yang ada pada industri “Mi Lethek”. Aktivitas-aktivitas tersebut kemudian digolongkan menjadi dua jenis aktivitas, yaitu aktivitas yang memberikan nilai tambah dan aktivitas yang tidak memberikan nilai tambah. Waktu dari masing-masing aktivitas tersebut yang selanjutnya digunakan untuk menghitung nilai process cycle effieciensy (PCE). PCE adalah efisiensi relatif dalam sebuah proses yang mer=wakili presentase waktu yang digunakan untuk menambah nilai pada produk dibandingkan total waktu yang digunakan produk selama dalam proses. Berdasarkan penelitian yang telah dilakukan, didapatkan nilai PCE awal dari industri "Mie Lethek" sebesar 12,05%. Perbaikan yang dilakukan ialah dengan mengubah tata letak pabrik dan melakukan perbaikan penjadwalan pemesanan bahan baku. Hasil perbaikan tersebut berhasil meningkatkan nilai PCE menjadi 15,08%.

Abstract

The reality showed that in the community of small scale food agroindustry there were many problems. The main prob­ lem was the technology difusion could not be transferred swimmingly, because social capital of small scale food actors were very weak, and it was only based on material bonds. Based on basic assumptions, economic value assessment of social capital in small scale agroindustries prove that social capital could reduce technology diffusion outlet conges­ tion, and increase agroindustry endurance and welfare. This research method used Participatory Rapit Appraisal by putting the priority on Focused Group Discussian process, participatory observation, and indepth interview towards facilitators, owners, workers and sellers or consumers of food products. The result of this research showed that the dominan social capital economic value identified were; family relation among agroindustry actors, cooperating in raw material suplying and stocking, products distribution and marketing, agroindustrial networking and sharing of enter­ prise management information. The contribution values were; labour productivity increase of 10­25 % and reduction cost of 12 %, material cost reduction of 5-10 %, increase of marketing efficiency up to 25 %, relative value of group­ ing and information sharing it could facilitate enterprice acess.  In terms of technology diffution the dominan factors were family relation, community guarantee, institution and communication media, teamwork­based success orienta­ tion based on trust. The reinforcement of food small scale industry security and technology diffusion could be done (1) reinforcing family relation, (2) reinforcing and developing enterprice grouping based on community education, (3) expanding enterprise group networking by providing social capital, distributor and product marketing, (4) mapping enterprise relations between producers and vendors or suppliers and (5) intensively utilizing facilitators from a variety of sources.ABSTRAKRealitas menunjukkan bahwa masih banyak permasalahan di komunitas agroindustri pangan skala kecil, terutama pada saluran difusi teknologi yang tidak berfungsi secara baik.  Akar penyebabnya diindikasikan karena lemahnya ikatan sosial antar pelaku yang lebih didasarkan atas ikatan material dan menyampingkan modal sosial. Penelusuran nilai ekonomi modal sosial pada agroindustri pangan skala kecil, merupakan bentuk pembuktian atas asumsi dasar bahwa modal social dapat memperbaiki tersumbatnya saluran difusi teknologi, sehingga meningkatkan ketahanan agroindustri yang pada gilirannya dapat menigkatkan kesejahteraan. Metode yang digunakan adalah Participatory Rapit Appraisal dengan mengedepankan proses Focused Group Discusian, observasi partisipatif, dan indept inter­ view terhadap pendamping, pemilik, pekerja dan penjual atau konsumen. Hasil yang diperoleh menunjukkan bahwa nilai ekonomi modal sosial teridentifikasi pada; hubungan kekerabatan antar pelaku agroindustri, kerjasama dalam pengadaan dan persediaan bahan baku, distribusi dan pemasaran produk, bermitra usaha dan sharing informasi pen­ gelolaan usaha. Besaran nilai kontribusinya; tenaga kerja terhadap peningkatan produktivitas 10 ­ 25 % dan penghe­ matan biaya 12 %, bahan baku 5­10 %, pemasaran  sampai 25 %,  berkelompok dan sharing informasi besarannya relatif tetapi memudahkan akses usaha. Faktor difusi teknologinya; hubungan kekerabatan, masyarakat poguyuban (tanggung renteng), tersedianya media komunikasi dan kelembagaan, serta orientasi sukses bersama atas dasar trust. Penguatan   difusi teknologi dan ketahanan agroindustri pangan skala kecil dapat dilakukan dengan memperkuat hubungan kekerabatan, pengembangan kelompok berorientasi usaha sebagai basis sekolah rakyat, memperluas jarin­ gan kelompok dengan penyedia modal, distributor dan pemasaran produk, memetakan relasi usaha diantara produsen dengan pemasok bahan baku, dan pemanfaatan intensif berbagai  pembinaan dan sumber.

Abstract

Kenaf fibres is one of the primary fibre commodities in Indonesia. However, the national total production of the fibre meets only 20-30% of the national consumption. In addition, most of the fibre quality is still low, where, 15-20 % of the fibre grouped into quality A, 40-50 % quality B and the rest, is grouped into quality C. It is likely that the resting process in the chain of fibre production is the main source of its low quality. n order to reduce rettin time and improve the fibre quality obtained, various efforts have been done to improve the rating processes, including the use of integrated processes of microbiological, mechanical and semi mechanical processes. The addition 2.5 % of adaptive starter of Bacillus polymyxa BCC-27 into 'wiling process was unsignificant (p > 0.05). It is likely that the case was nullified by the addition of 0.005 % urea. The six and three hour per day circulation treatments could enhance the condition of resting processes; mainly pH and temperature, but still less than DO. Without circulation unsignificant (P > 0.005) toward the degradation of peclin, holocellulose, cellulose and lignin. The fibre produced by the sixth combination treatments, that are circulation treatments and 0.05 % urea by culture enrichment 2.5 % meets the standart quality A. End-point rating or top resting accured on the process period of after five day. The process is still under resting on the fifth day, but over 'wiling after the seventh day.

Abstract

The combine harvester in Yogyakarta Province Special Region has a small size because it is used to harvest rice in a narrow area. The purpose of this study is to determine which parts of the mini combine harvester machine are not ergonomic and need to be improved so that the operator can work comfortably and safely. The types of mini combine harvester machines investigated in this study are QUICK H140R, TANIKAYA Ironbee HT12, and JAP001. Results showed that, for the three combine harvester machines, there was a mismatch in the physical size of the engine and the anthropometry of the operator. The main problems of the mini combine harvester machine are less ergonomic seat, inappropriate placement of the control table, hand activity in the maximum area, narrow workspace for leg movements, and less supportive footstep for the operator to work while standing. This information is expected to be utilized by Indonesian mini combine harvester machine designers so that the new design of combine harvester machines will be ergonomic, safe, and comfortable.

Abstract

Herbal tea is a functional beverage with significant health benefits, produced from processed plants, namely Chinese teak (Cassia angustifolia Vahl) and soursop leaves (Annona muricata L). However, herbal industry faces a productivity problem due to the production process time caused by human factors, machines, and raw materials. Productivity can also be affected by non-value-adding activities in the production processes, such as unnecessary inventory and overproduction. Fossil energy used by industry to generate electricity contributes to the production of solid waste, posing a long-term environmental risk. To address this problem, Objective Matrix (OMAX) is needed to measure the industry production rate, where all non-value-adding activities are reduced in lean and green productivity. The concept of lean and green productivity facilitates the identification of all activities to determine the locus of the highest waste, material, or energy usage. Therefore, this research aimed to propose alternative improvements for enhanced productivity by assessing production rates and identifying generated waste, energy consumption, and emissions. The results show that herbal industry had low productivity, 0.4, on a scale of 1. To improve efficiency, recommendations for lean aspect were based on forecast demand and workload. This improvement was projected to raise Process Cycle Efficiency (PCE) ore from 7.97% to 9.05% and reduce solid waste by maintaining and repairing filling machines. Green aspect could be improved by turning off idle facilities and machines, thereby minimizing electricity energy usage to 43.37%.
