Abstract

Last 10 years, more than 50 papers and handbooks have been published on the topic of sustainable production and processing in the coffee commodity. Review process is used by desk study based on several scientific journals which are related to the topic. It was found by scientific publisher webs such as Scopus, Ebsco, Academia.edu, Researchgate, Portal Garuda, DOAJ and Google Scholar. Technically, sustainability was discussed at least 3 aspects, i.e. economic, social and ecology. In global growth, particularly a coffee commodity has been disturbing production which was caused by global warming, fair-trade and social conflict. On the other hand, dynamically there has been increasing of demand (export and local) due to lifestyle. Based on the fact, the realistic solution is needed on these matters. This study has done several articles reviewed and synthesized. The systematic of it’s through content analysis on that article and then clustered by a topic which assessed. The realistic solution complied based on economic, social and ecology aspects in a sustainable production and processing. Finally, we suggest several new techniques and products (downstream) which could be developed to reach the sustainability and processing of the coffee, especially cold-brew for new coffee product.Keywords: coffee, processing, state of the art, sustainable production

Abstract

This research deals with identification of potential hydrological drought at 15 watersheds in Eastern part of East Java Province. Hydrological drought events is indicated by water deficits at the main river of the watersheds during certain period of record. Discharge data from 15 watersheds in East Java are used as main input for this analysis. TLM modul based on HydroOffice platform is used to calculate the deficit. Deficit event is counted when the discharge during more than > 7 days is below the threshold level. The threshold level is set up using percentile 90% (Q90). The value of Q90 is determined from discharge times series. Furthermore, the discharge is rangked from high to low flow. Results from TLM are then imported to EXCEL for further analysis. Furthermore, GIS software package (Quantum GIS) is used for mapping the spatial variation of discharge values (avarage, maximum, Q90), frequency and duration of deficits events. This analysis produces the spatial maps of discharge value and deficit events ( averaged annually).Keywords: TLM, hydrological drougth, percentile 90 (Q90), discharge

Abstract

Cocoa is the one of agricultural commodities with high contribution in national economy. Low quality and defeccted product during process were still problems faced by cocoa processing unit. The objectives of this research were to identify defeccted product during processing and to create alternatives ways to solve problems based on SPC. SPC (statistical process control) with p chart, pareto chart and fishbone chart were implemented in this reasearch to analyze data which collected from field. The results of this research found that all of processing unit in the plantation were still under control (inside control range). Over ripe (almost damage) was dominant damage product during harvesting process, and broken bean was dominant damage product during drying process. Man, method, raw material, machine (tools) and environment were important factors (cause factors) in of cocoa bean process. Proportion of worker number, improved skill and high intencity of controlling were still required to improve cocoa bean product.Keywords: Statistical Process Control (SPC), processing, cocoa beans
