The Best Solvent And Extraction Time In Pectin Production made From Waste Of Jackfruit (Bark and Straw)
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%
Post-harvest Quality Evolution of Jonagored Apples (Mallus domestica cv. Borkh) during Shelf life Storage
The experiment was carried out to study the quality evolution of Jonagored apples (Mallus domestica cv. Borkh) during 14 days of shelf life prior to controlled atmosphere (CA) storage. The apple were harvested from the “Fruitteelt centrum” (Velm, Belgium) in 24 September 2010 (optimal picking) and 8 October 2010 (late picking) and were stored at 18°C and 65% RH to mimic the shelf life condition. The apple then were measured for colour, firmness, soluble solid content (SSC), titratable acidity, ethylene production rate, O 2 consumption rate, CO 2 production rate and respiratory quotient (RQ) at 0, 7 and 14 days after harvest. There was a significant effect of shelf life duration in colour of the apple. The apple turn its colour from green to yellowish green at the end of shelf life. The optimal-harvested apple had a greener colour than the late-harvested apple at 0 and 7 days of shelf life except at 14 days where the older apple had a greener colour. Although the effect was not consistent, firmness of apple was affected by shelf life and picking time as well. Firmness decreased along shelf life and the optimal-harvested apples were firmer than the late-harvested apple. Apple’s acidity decreased during shelf life from 8,43 mL NaOH (optimal-harvested apple) and 8.85 mL NaOH (late- harvested apple) to 7.58 mL NaOH (optimal-harvested apple) and 7.03 mL NaOH (late- harvested apple) at the end of shelf life. Yet, acidity was not affected by picking time. Ethylene was considerably increased throughout shelf life and the late-harvested apple had a higher ethylene production level than the optimal-harvested apple. Optimal-harvested apple had a lower respiration rate than the late picked apple. Older apple consumed oxygen and produced carbon dioxide at a higher rate than the younger apple. Moreover, respiration rates as represented by O 2 consumption rate, CO 2 production rate and respiratory quotient (RQ) tended to increase along shelf life

The improvement formulations for the proposed Value Stream Mapping were made by determining optimal crew size, work-cell design, Kanban design, and idea of autonomation. The improvement formulations of the proposed Value Stream Mapping could reduce work in process (inventories) of 57.81 %, delays amounting to 55.52 %, and transportations between work stations at 52.54 %. The company’s PCE increased by 12.06 %
Assessment of Workers’ Body Temperature and Workload in Tomato Production Greenhouse Work
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
The Role of Logistics Service Providers in the Distribution Channel of Imported Perishable and Processed Food Product to Java Island, Indonesia
Today fierce competition has highly enforced the company to focus more on their core competency and has encouraged them to strengthen competitive advantage. This condition reinforces the role of logistics service providers (LSP) to help company run their supporting activities. This research aims to identify the characteristics of LSP and to analyze their role in the distribution channel of imported perishable and processed food products in Indonesia. Convenience sampling was employed as sampling methodology and in-depth interview was used to collect detail information from respondents including private stakeholders, port authorities, freight forwarder association and retailers. The research results show that the characteristics and size of the company affects the involvement of LSP in the distribution channel. The roles of freight forwarders (FF) extensively include pre-customs clearance, customs clearance and post-customs clearance. Furthermore, the role of FF considerably contributes to the ease of arranging international shipment. The role of distributor plays vital role in the tracking and tracing system and timeliness of distribution channel. Meanwhile, the role of FF and transporter is fairly low in encouraging track-able and traceable distribution channel. Further improvements are needed to encourage better distribution channel performance
