Publisher : APTA and DTIP FTP UGM

In Indonesia, the scope of agroindustry are related to the food and non-food industry managedby Small-Medium Enterprises (SME). The classical problem of Indonesian Agroindustry wererelated to logistic, infrastructure, technology, high-cost economy, regulation, and financingconstraint. Therefore, an innovative business model is required for competitive and sustainableSME. Importance rate of the model can be defined by determining some criteria in a businessmodel. Analytical Network Process (ANP) is required to determine importance rate of businessmodel. However, ANP could not minimize the subjectivity factor of the respondent indetermining the criteria. Application of Conditional Probability Co-occurrences Matrix (CPCM)is required to minimize the subjectivity factor by comparing priority weight of each criterias. Theresearch objectives are: 1) To apply ANP method for representing business model criteria andattribute of SME; 2) To apply CPCM method for criteria pattern extraction. The case study ofresearch is SME Bakpia Tela Ungu and Telopia. CPCM Pattern extraction of Contrast, Energyand Local Homogeneity indicated the significant different of business model criteria betweenfood, non-food agroindustry and local governmental board. The research results indicated thatthere were different subjectivity to determine criteria priority weight.

Many workers work in the tomato production greenhouse in Japan, exposed to unfavorable environmental conditions during their work, especially in the summer season. In this study, workers’ body temperatures of internal, facial, and head area temperature were measured, so did the workers’ workload. They were related to environmental conditions of solar radiation and air temperature to clarify their relationships. Three workers in semi-commercial tomato production greenhouse were employed for this research. Jobs were classified into upper and lower canopy job, to examine the working condition in the greenhouse. Ear thermometer and thermal camera were used to measure worker’s body temperatures. Workload of the jobs was assessed and determined the level with Heart Rate Reserve (HRR). Workers’ heart rate itselves was measured using finger pulseoxymeter. Significant correlations were found between workers’ body temperature and environmental conditions. Worker’s workload could change on changing environmental conditions. Workload level of tomato production greenhouse job is considered low, as the job relatively does not require heavy physical work.

Publisher : APTA and DTIP FTP UGM

Jackfruit barks are known to have fairly high pectin content, by 4.7% on wet and 22.5% on dry barks. The content is sufficiently highboy make it worthy of being raw material for producing pectin. Pectin is a polygalacturonic acid containing methyl ester. Pectin is a high- value functional food that is widely used as gelling agent and stabilizer. Approximately 65 until 80% jackfruit barks were wasted from the industry and it were only useful for animal feed . To increase the added value of it, so that jackfruit barks were extracted to get the pectin. This research used randomized block design (RBD) with 2 factors:(i)the type of solvents(hydrochloric and citric acids, with pH = 1.5) and (ii) extraction times (30, 90 and 150 minutes). Each factor is conducted in triplicate in order to get 18 units of experiment. Before analyzed, the jackfruit waste (bark and straw) was powdered during sample preparation. Later on, the yield, equivalent weight, methoxyl, galacturonic acid, and ash contents of the powdered, then were analyzed and used as pectin’s parameters. Multiple attribute method (Zeleny method) was used to determine which combination of treatments that produced pectin with the best pectin’s parameter. The best pectin made from jackfruit waste is derived from the combination of citric acid solvent and the extraction time of 150 minutes, resulting in yield of 10.21%, methoxyl content of 9.25%, equivalent weight of 1088.43 g/mol, ash content of 2.79%, and galacturonic acid content of 47.40%.
