The Technology of Robusta Coffee Decaffeination for Small and Medium Scale of Industries

The research on the Technology of Robusta Coffee (Coffea canephora L.) Decafeinationfor Small and Medium Scale of Industries had been carried out. The purpose of the research was to get the technology of decaffeination on robusta coffee. The research was conducted by using Completely Randomized Design (RAL) with raw material samples taken from specified area (purposive sampling), there wereMuara Enim, Pagar Alam and Lubuk Linggau Districts and then combined by composites. The main apparatus were 10 liter silindric container and 10 liter steamer with simple condenser. The treatments include boiling and steaming coffee beans at 100°C for 30, 60 and 90 minutes. The results show that the process of decreasing caffeine (decaffeination) by boiling 30, 60 and 90 minutes resulted caffeine content of 0.66%, 0.45% and 0,40% each; whereas by steaming resulted 1.65%, 0.42% dan 0.45% each. The results of this research can be applied by small and medium industres (SMIs) because simple and low cost

Integrasi Critical Path Method (Cpm) Dan Line of Balance Method (Lob) Dalam Perencanaan Proyek Jalan

Aplikasi metode Critical Path Method (CPM) secara luas dalam perencanaan proyek konstruksi disebabkan karena kesederhanaan dan kemudahan penggunaan serta lebih fleksibel dalam hubungannya dengan waktu dan logika. Di sisi lain, metode CPM jika digunakan pada proyek repetitif seperti proyek jalan akan menemui kendala terhadap ketidakmampuan untuk memelihara kontinuitas kerja bagi tenaga kerja dalam proyek. Metode Line Of Balance (LOB) yang umumnya digunakan pada proyek repetitif menemui kendala apabila jaringan kerja dan hubungan logika aktivitas yang banyak.Tujuan penelitian ini adalah untuk memberikan gambaran mengenai perencanaan proyek jalan dengan mengintegrasikan keunggulan-keunggulan dari metode CPM dan LOB dalam hal pemanfaatan waktu tenggang (float time) dan perataan sumber daya. Penggunaan waktu tenggang pada proyek jalan akan berdampak pada penggunaan sumber daya secara merata serta akan menghemat biaya proyek.Penelitian dilakukan dengan studi literatur dan diaplikasikan dengan contoh kasus yang berhubungan dengan perencanaan proyek jalan.Hasil yang diharapkan dengan penelitian ini adalah pemanfaatan waktu tenggang aktivitas nonkritis pada proyek jalan dan perataan sumber daya proyek. Dengan pemanfaatan waktu tenggang dan perataan sumber daya akan menghemat penggunaan sumber daya dan menyelesaikan proyek tepat waktu.Kata

The Influence of Business Models, Information Technology on the Quality of Accounting Information Systems Digitizing MSMEs Post-COVID-19

Many organizations realize the importance of building information systems based on the formulation of business models and implementing them into company activities. The survival of an organization is determined by its ability to compete in the market. In modern systems, there are dependencies between enterprise information systems, business models and enterprise business processes. There is an equally strong influence between business models and information systems. The goal achieved between business models and information systems is to maintain a balance between the three dimensions of sustainable development, namely: environmental, social, and economic. The research method used is qualitative with a field approach, an institutional approach, and a library approach. The types of data used in this research are primary data and secondary data. The data collection technique used is observation and literature study both nationally and internationally, while secondary data comes from journals, proceedings, government regulations, and statutory regulations. The output target achieved is obtaining business models, information technology on the quality of MSME accounting information systems after Covid-19

Does Internal Control Promote Employee Engagement Drivers? A Systematic Literature Review

Internal control (IC) and employee engagement (EE) are critical organizational factors, whereby one is part of accounting principles, while the other is under the human resource domain. This study investigates the linkage between the implementation of IC and the factors that drive EE, specifically, how internal control measures impact employee engagement drivers. The research uses a systematic literature review by reviewing published articles about EE in journals published by Web of Science, Scopus, and Google Scholar from 2013–2022. The results show that internal control practices can also resonate as the drivers of EE. The findings mean that an organization will benefit from implementing internal control correctly because it will serve two objectives. The first objective is to ensure record accuracy, boost operational efficiency, reduce risks, safeguard assets, and encourage compliance with laws, policies, and regulations. The second objective is to promote employee engagement levels. The findings offer opportunities for further empirical research to back up the conclusions drawn here and better comprehend the business world\u27s reality

Detoxification of Hydrogen Cyanide Acids (HCN) From Rubber Seed (Hevea Brasiliensis Mull. Arg) Through Some Physical Treatment as Fish Feed Ingredients

The research was carried out on July until August 2013 in the Fish Nutrition Laboratory, Faculty of fisheries and Marine Science University of Riau, Pekanbaru. The purpose of this study was to remove HCN from rubber seed and See influence treatment of nutrients. so the rubber seeds can serve as fish feed constituents. This study used a Randomized Complete Design (RAL) with nine treatment three times in rreplication. R0 = Without treatment, R1 = Boiling rubber seeds open for 30 minutes, R2 = steaming open rubber seeds for 30 minutes, R3 = rubber seeds drying out under sunlight for 12 hours, R4 = rubber seed soaking in running water for 36 hours, R5 = combination of steaming open rubber seeds for 30 minutes and drying out for 12 hours, R6 = combination of soaking for 36 hours with steaming open for 30 minutes, R7 = combination of soaking rubber seed soaking in running water for 36 hours with an open boiling for 30 minutes, R8 = combination of Boiling rubber seeds open for 30 minutes and drying out for 12 hours with sun light. The result showed that combination of Boiling rubber seeds open for 30 minutes and drying out for 12 hours with sun light (R8) was the most effective way to decrease HCN content, and gave better quality of rubber seed meal for ruminant feed

Spatial-Based Earthquake Disaster Risk Analysis In Parepare City, South Sulawesi

The research objectives are to create hazard maps, vulnerability maps, spatial-based risk analysis in the form of earthquake disaster risk mapsin Parepare. The earthquake disaster riskanalysis applied Geographic Information System spatial-based overlay analysismethod. Research to identify earthquake hazard risk was based on earthquake hazard factors, the vulnerability factor of population density and capacity factor. Earthquake hazard map wasgenerated from calculatingThe Peak Ground Acceleration  value, procured from the source map and hazards of earthquake in Indonesia 2017 (Team 9)the peak acceleration map in the base rock for the probability exceeded 2% in the last 50 years. Automatic terrain classification map using SRTM (250 m or mesh 1 km) was obtained from Koiwahashi and Pike (2007)and the average distribution of S-waves, shallower than 30m (AVS30),were acquired from J-SHIS for each topographical characteristic (16 classes or 24 classes). The vulnerability data were used for calculating population exposure index and loss index, and the vulnerability was obtained from Focus Group discussion. The earthquake disaster risk index calculated by useing AHP method (Analytical Hierarchy Process).The calculation results showed that the villages with a high risk of earthquake disaster were Bukit Harapan Village, Bukit Indah Village, Ujung Lare Village, WatangSoreang village, and Lapadde village, while the village having the lowest risk of earthquake was Mallusetasi vill
