Authors: Soriano C , Gita D I , Pertiwi D , Rizaldianto A R , Farhah A D
Published: April 2020

Bio-drying is a technology used to reduce water content in waste using microorganisms that naturally increase the temperature in the decomposition process. With this process, the water content can drop more within a month. Bio-drying produces a product in the form of Solid Recovered Fuel (SRF) which is produced from partially degraded waste. To obtain a waste that is not fully stabilized and maintains a high biomass content, degradation of organic compounds is carried out partially. During the bio drying process, temperature affects the degradation process. Temperature affects the bio drying, which will also affect the bio drying product that is indicated by the value of water content. Therefore, in this study, the change of process parameters will be explained, which is in the form of temperature and water content, that is caused by the difference in the air discharge entering the reactor (0, 2, 4, and 6 l/m) with the initial water content of 60%-65%. After 30 days, the optimum airflow is 4 l/m with a decrease in water content of 58.29%; on the last day of the bio drying process (30th day).

Construction projects are large-scale works that are mostly done in open areas. This large and open activity has the potential to produce waste and carbon footprint. Therefore, the purpose of the research is to find out the causes, impact analysis, and possible mitigation of waste and carbon footprint in the construction project. Survey and in-depth interviews with construction projects become research methods. The results showed that the causes of waste were dominated by worker factors while the main causes of waste in the design phase are client requests, DED changes and complexity, and design errors. Meanwhile, carbon footprint occurs because it does not use renewable energy and environmentally friendly materials. The impact of indirect waste is 8.93% of the total workers’ budget, while direct waste is 5.64% of the material budget, which is at the contractor’s tolerance threshold of 3-6%. The carbon footprint in the production phase still dominates the contribution to the amount of carbon footprint produced when compared to the transportation, fabrication and installation phases.

This study aims to explore the role of social capital in promoting sustainable rural development area in Banyumas Regency, Central Java. This study departs from the problem of a lack of community involvement in a rural development area. Community force or social capital has a potential role in determining the future of rural development. Also, Law No 6/2014 on Village, in particular, Section 2, mentions that social participation becomes a vital principle of the rural development area. Using three villages in Somagede Subdistrict Banyumas Regency, this study applied a legal research approach and qualitative case study to understand the existing community forces in supporting a pilot project of the rural development area in Somagede Subdistrict. Informants were purposively selected representing community leaders, village government, young leaders, and village development cadres. Our results show that various community-based organizations have developed well in three villages. There are at least four types of community-based organizations, namely tourism, agriculture, animal husbandry, and small industries. Besides, local wisdom also still exists in three villages, including Suran and Sadrana. Klinting Village, which is partly a Hindu community, celebrates Nyepi. In terms of performing arts, all three villages have lumping horse and wayang lengger performing arts. The Tanggeran Village specifically has additional performing arts from Beans. From the legal perspective, the implementation of the rural development area project should take community-based organizations and local wisdom into account. The village law also states that the application of the rural development area will require all elements in the village to have a common perception, shared vision, joint mission, and common purpose. The involvement of social capital elements in rural development will promote the sustainability of the agricultural development area project. Therefore, the findings of this study contribute to an understanding of the role of social capital in promoting sustainable development area.

Published: April 2020

The people of Yogyakarta City who live in the watershed always suffer in the rainy season. The threat of flood disaster, landslides and dengue fever has become a routine that has never been resolved. This article aims to discuss collective actions of urban communities in disaster risk reduction. This study used a case study approach. The author chose the research location in Kampung Gambiran, Yogyakarta City, because it could explain the stages of collective action of urban communities in reducing disaster risk faced each year. The findings showed that the collective actions in Kampung Gambiran could reduce disaster risk. The stages of collective action in Kampung Gambiran start from 1) the first stage: the emergence of disquiet and ideas, 2) the second stage: the formation of an environmental community, and 3) the third stage: achievements. The collective action of the community initiated the city government to create a Program Kampung Hijau, one of which aims to mitigate flood disasters.

Published: April 2020

Urban farming through aquaponics has begun in Semarang, since 2016. More than eighty people formed an aquaponics community. The community has conducted routine training on aquaponics to develop urban farming through this system. But the number of aquaponics was unstable. Therefore, the purpose of this research was to find out the motives and dynamics of the aquaponics community in supporting urban farming. The method of this research used a qualitative approach. The results of studies with the analysis of the theory of motives and group dynamics show that this community was in the class of altruism and collectivism motivation so that it has a chance of sustainability even though at certain moments it decreases. As for the dynamics of some actors who think that they weren’t in line with expectation, factors emerge that weaken the community in aquaponic. However, those who have altruism and collectivism motives will tend to survive because they got personal satisfaction and a good impact on their environment. Therefore, when many actors leave this system, they keep trying to return to carry out aquaponic activities in support of urban farming in Semarang.

Jajar River is geographically located between Demak and Grobogan Regency area. For most part, Jajar River which lies on lowland area is mainly utilized for agricultural purposes. The utilization of the land around the area of Jajar River might potentially cause several environmental problems such as river water contamination, causing degradation of river water quality. Generally, river has the capacity to purify itself by decomposing any pollutants blended in the water. This capacity is called self-purification. The aim of this study is to determine the level of self-purification capacity (time and distance of water purification) using Streeter-Phelps equation, by obtaining data about organic pollutant concentrations DO and BOD at a certain pollutant point in a river. By using Streeter-Phelps equation, it is expected to find oxygen reduction curve toward time and distance. Deoxygenation and reaeration constants are needed to draw the curve. Moreover, Streeter-Phelps equation can generate the oxygen reduction curve which shows self-purification distance. The results showed that there was no natural purification process in Jajar River. In other word, the water sample test in each segment showed the existence of waste input, which was indicated by unacceptable results of DO and BOD parameters. In this condition, the river ecosystem had not been able to purify the water from BOD input. It supposedly happened due to the inability of DO concentration to return to the ideal condition of anaerobic river from waste contamination in the extended segments.

Published: April 2020

As one of the province that borders DKI Jakarta, West Java has been named the most populous province in Indonesia. This has an impact on land cover change in the region. For example, a lot of land that was once a vegetation land, is now converted into built up land. From previous studies, changes in land cover are caused by several factors, one of which is the existence of cities/regencies in the West Java region itself. However, is yet known for certain that changes in land cover are influenced by only the closest city/regency or all cities/regencies. Therefore, an analysis of the influence of cities/regencies existence towards land cover change in West Java is needed based on geospatial data. One calculation method to determine the influence of cities/regencies existence towards land cover changes is Binary Logistic Regression (BLR). BLR is used to analyse binary phenomenon. This study shows that to determine land cover change at a point in the province of West Java it is sufficient to be seen not only from the influence of the closest city/regency, but also necessary to be seen from the influence of all cities/regencies.

Thekelan Hamlet is one of the tourist hamlets in Kopeng District, Semarang Regency, Indonesia, which is near the Gunung Merbabu National Park area. Furthermore, the potential of biomass from the livestock and agricultural sectors in this village has not been well utilized. The purpose of this study is to determine the amount of energy use in the Thekelan hamlet, and analyze the potential use of renewable energy (biogas) to substitute conventional electricity. The method used in this research is descriptive qualitative combined with IPCC default methods based on a questionnaire from 40 respondents taken randomly. The result of the research shows that the use of energy sources from fuel wood is 9, 830 kg and LPG is 215.5. The number of cattle in the hamlet of Thekelan is 70 heads and 34 goats. The largest GHG emissions are generated from the use of fuel in animal husbandry activities with a value of 0.206 Gg CO2e/year while the lowest GHG emissions from LFG utilization activities are 0.008 Gg CO2e/year. The total emissions of all activities are 0.599 Gg CO2e/year. The use of biogas as an alternative energy is known to be able to reduce GHG emissions by 34.3% because the substitution of fuel wood and LPG is transferred to the use of biogas. This research is expected to be a stimulant and basic data for the realization of low carbon energy conscious villages.
