Sago solid waste as by product result of sago palm processing potentially have great value for some bio processing such as source of carbon on microbes substrate. Utilization of sago solid waste as substrate for filamentous cyanobacteria cultivation is a rareresearch activity in Indonesia as one of the three leading world companies producer of sago starch. Therefore, we focused on sago waste treatment using cyanobacteria agent in order to rid the waste and gain the value of nutrition rich starch from that waste. Several concentrations of growth media contain sago solid waste were tested into cyanobacteria culture and solid waste hydrolysis as pretreatment more conducted in the research. Result shows that addition of sago solid waste (50, 500 and 5000 ppm) into media can increase the algae biomass production which is rich of carbohydrate and protein.The proximate value of biomasses with sago solid waste treatment was exhibited significantly higher than control. During cultivation exposure time, the solid waste is gradually consumed by the algae. The study implies that sago solid waste can be used as substrate for the biomass production of filamentous cyanobacteria which is known as source of active compounds, potential resource for valuable bioproduct.

Improvement for educational quality Indonesia is continually realized by the issuance of various policies, one of them is Minister of Education and Culture Regulation No. 23 of 2017 on School Day. This regulation stipulates that school days begin on Monday to Friday. Hence, the review of this policy is important to identify how extent the effectiveness of its implementation. This study aims to determine the effectiveness of the implementation of five days school program in terms of psychological aspects and academic aspects. Also, this research is conducted using a mix method design with sequential explanatory data analysis model. Results indicated that the effectiveness of five days school program implementation could be observed from its purposes and impacts. Based on the findings at the psychological aspect indicator, there are five indicators that have not met the standards of Minister of Education and Culture Regulation thus 5 days school has not been effective to develop psychological students, meanwhile from the academic aspect, overall research indicator is in accordance with expected standards hence 5 days school has been effective in supporting the academic development of students. This research serves as a reference for a stakeholder to make regulation and how to make an effective learning process that can solve studentsÃ¢â‚¬â„¢ psychological during five days of school.

Microalgae are photosynthetic microorganisms that have potential to produce some useful chemical substances such as carbohydrates, proteins, and lipids. Microalgae are also known exhibited ability as a bioremediation agent. This report is emphasized on analyzing the growth rate and nutritional content of microalgae including carbohydrate, protein and lipid from selected isolates LIPI11-2-AL002 that treated with sago waste. Microalgae were cultivated into hydrolysed sago ?ampas? at the concentration of 0,50, 500,5000 ppm, and medium AF-6 (as control culture) respectively.Therefore selected microalgae isolate was cultivated in series of cultivation volume start from 100 mL until 5 Liter media gradually. Observed parameters were covered cell viability (growth) and proximate content of biomass including carbohydrate,lipid and protein content. The results showed that the carbohydrate and protein content in the algal biomass was increase along the addition of series sago ?-ampas? concentration.The highest concentration of addition the sago ampas is 5000 ppm which is limit for the algal survival. In the highest treatment of sago waste the alga l proximate contents were 261.09 ppm of carbohydrate, 5.12 ppm of protein and 3.61% per of lipid dry weight respectively. In addition, the toxicity effect of fermentation product was not appeared in a toxicity test using gold fish komet(Carassius auratus).

In a world increasingly concerned with environmental sustainability and corporate responsibility, the relationshiop between water disclosure, social entrepreneursip, and the cultivation of the entrepreneurship ecosystem emerges as a critical nexus. Water is the essensial need for human life and business life. Entrepreneurial concern for these issues also influences access to financing and market. These problems have received much attention from researcher, but there has been no attempt to synthesize the results. This research aim to explores and synthesize the literature related water disclosure and social entrepreneurship in the entrepreurship ecosystem. The analysis was based on Scopus database in the last decade and PRISMA protocol and VOSViewer was used. This study performs co-occurrence and co-authorship analysis. Social entrepreneurship, sustainability, innovation, water disclosure, and strategy are some of the frequently emerging variables. The results of network analysis show that social entrepreneurship and water disclosure are linked by variable stakeholder, economic and social effect, and sustainable development. It highlights that water disclosure and social entrepreneurship is a mandate of the stakeholders and its implication is that the entrepreneurial ecosystem has moved towards sustainable development.
