Authors: Hardyanti N , Sudarno S , Jayanti A E 
Published: April 2020

Abstract
One of the dominant compound in a personal care product is sodium lauryl sulfate (SLS). So in this study, SLS is used as a pollutant that might influence the anaerobic digestion treatment. The effect of SLS on the efficient removal of ammonium (NH4+) and COD can be investigated with anaerobic batch reactors. In these reactors, house septic tank sediments were contacted with artificial wastewater with ammonium concentration 30 mg NH4+−N/L and 300 mg/L COD concentration. Reactors are operated for 15 days with variations of SLS concentration 0, 5, 10, 50, 100 mg/L. The best COD removal efficiency and the rate is in the 5 mg SLS/L with the efficiency value of 99,6% and a reduced rate of 19,67 mg/L. The efficiency and rate of COD removal continue to decrease with increasing SLS concentrations. Meanwhile, the best ammonium (NH4+−N) removal efficiency and the rate is in the 0 mg SLS/L with an efficiency value of 73,32% and a reduced rate of 1,30 mg/L. The magnitude of the efficiency and removal rate of ammonium also decreases with increasing SLS concentration. Temperature and pH values for all reactors are in the range of 26-28°C. The pH values in the five reactors were relatively the same both without and with the addition of SLS concentrations.

Abstract
Wastewater is the liquid waste generated after being used for different purposes. It has a great impact on the environment when discharged untreated or partially treated. The poor management of wastewater at Gacuriro wastewater plant leads to the discharge of subsequently untreated and partially treated wastes. Therefore, the research focused on the assessment of the efficiency of Gacuriro wastewater treatment plant. Samples of wastewater were collected at the inlet and outlet of the treatment plant for laboratory analysis. Parameters tested include pH, Temperature, Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Coliform (TC), Oil and Grease, and Total Phosphorus (TP). Inlet and outlet results are 112.5-364.5 mg/l, 60-190.2 mg/l for BOD; 447-820 mg/l, 46.6-300 mg/l for COD, 19-24 mg/l, 12-18 mg/l for TSS; 6.8-9.05 mg/l, 6.4-5.75 mg/l for TP, 2419.6-50000 counts/100 ml, 1730-30000 counts/100 ml for TC, and 1.012-1.079 mg/l, 0.75-0.923 mg/l for Oil and Grease. Their percentage reduction of efficiency were in the range of TSS (62.50-75%), COD (63.05-78.74%), BOD5 (69.97-83.70%), Oil and Grease (48.67-62.19%), TP (49.26-60.82%), TC (57.14-64.00%) while average inflow and outflow discharge are 2.5 l/s and 1.5 l/s, respectively. The effluent from the treatment plant needs improvement in disinfection systems to remove bacteria out of discharged effluent.

Published: April 2020

Abstract
Water loss is a serious problem in the world of drinking water management. In addition to disrupting services that result in economic losses, pipe leaks can cause health problems if contamination occurs. In this paper, the author will conduct a potential risk analysis causing water loss to address technical problems in the management of transmission and distribution pipelines in the Regional Water Supply System of Bregas in Central Java, Indonesia. The author tries to present a simple method for assessing the potential risk of water loss from the physical aspects of the network and the environment with passive control. Passive control is a reaction to leaks that are usually reported by customers or recorded by company staff. This study concludes that the pipe condition had the highest potential risk compared to other factors. Transmission pipelines from Kaligiri and Gombong springs are considered to have the highest risk of water loss. Although incomplete, this research can be a valuable reference source for practitioners and researchers dealing with water loss management in distribution systems and providing a road map for future research.
Addition of Solid Recovered Fuel (SRF) to the Bio-drying Process and the Effects of Variation in Air Discharge on Temperature Parameters and Urban Waste Water Content
Authors: Soriano C , Gita D I , Pertiwi D , Rizaldianto A R , Farhah A D 
Published: April 2020

Abstract
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).
Lean Construction: Evaluation Of Waste And Carbon Footprint In Construction Project
Authors: Wibowo M A , Sholeh M N , Rizkyawan A W 
Published: April 2020

Abstract
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.

Abstract
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.

Abstract
The tsunami of Sunda Strait that struck Banten and Lampung on Saturday, December 22, 2018 had been claimed many lives, especially in three most affected areas, Pandeglang, Banten, and South Lampung. To minimise the casualty, disaster preparedness program needs to be initiated from the smallest element, such as family or household. Family members need to understand the steps that are needed to be taken for life survival and property protection during the disaster situations. This research was conducted to determine the effect of family resilience towards household disaster preparedness in response to disasters in Sumur District, Banten. The participants of this study were 174 respondents from the family affected by the tsunami. Disaster Preparedness Measured by LIPI-UNESCO/ISDR Instrument and the instrument for Family Resilience by Walsh Family Resilience Framework – Questionnaire were used in this research. The finding shows that family resilience had a significant contribution to the household disaster preparedness by 27.1%. Furthermore, this study also found a high level of household disaster preparedness among families in Sumur District. However, household disaster preparedness and family resilience need to be socialized continuously due to many family members do not have adequate knowledge about disaster preparedness.
