Abstract
The existence of the batik industry is economically enough to provide a great livelihood for the community. The increasing demand of batik by the community has an impact on the growth of the batik industries in various regions in Indonesia. However, this industrial activity has a negative impact in production of liquid waste disposal. In batik production process, the liquid waste was produced by more than 95% which is emitted from process of soaking, heating and rinsing. Liquid waste has the potential to cause environmental pollution and affect the condition of living organism, including humans. One of efforts to reduce pollutants in batik waste water is by using biodegradation. Biodegradation is usually carried out by a consortium of a number of microbes. The objective of this study was to evaluate the potential of microbes for batik waste water degradation. Samples were taken from water and sludge contaminated batik waste water in the sewerage and river at Banyumas. Isolation and purification using the dilution planting method were conducted, to obtain pure culture using the pour plate technique, and maintenance of bacteria using streak culture. About 8 genus of microbes found in water bodies that have been contaminated by batik waste water are Mesophilobacter, Methylococcus, Agrobaacterium, Neisseria, Xantobacter, Deinococcus, Sporosarcina, and Bacillus. The result showed that BOD degradation in batik waste water by microbial consortium was about 85.71%. Regarding on the result, it can be concluded that bacteria found in the sewerage and river were able to degrade pollutant from batik wastewater.

Published: August 2019

AbstractBase flow is the portion of stream that is not run off and results from seepage of water from the ground into a channel slowly over time. Base flow is considered to be the groundwater contribution to stream flow. Estimates of the amount of base flow can be derived from stream records. This study is about groundwater recharge condition at two sub watersheds in Krueng Peusangan: sub watershed of Lut Tawar and sub watershed of Teupin Mane (Krueng Teumbo). The Krueng Peusangan Watershed is one of priority for watershed management because this watershed is in a critical condition. The Krueng Peusangan Watershed is an important water catchment area in Aceh where there are one million people depend on life from the water source watershed, such as dringking water, agriculture, and fisheries. The Krueng Peusangan includes four regencies, an upstream Aceh Tengah, a midstream area in Bener Meriah and downstream area in Bireuen and Aceh Utara. This research aims to get groundwater recharge using Seasonal Recession Method and Base Flow Separation Method. Both of methods were used to estimate groundwater recharge for each peak in stream flow during the period of record (2008-2012). The results showed that the trend pattern of the stream hydrograph could be explained using the exponential function where the dots lowest discharge that is the end of the recession (y) than any period of time on stream hydrograph semi logarithmic (x). The regression formula for the watershed of Krueng Peusangan is: y=1.3x−0.12(Lut Tawar - Wih Nareh) and y=1.94x−0.42(Teupin Mane-Krueng Teumbo). The filtering method (Base Flow Separation Method) by Chapman (1999) gave a lower percentage of the low flow component (base flow) for Sub Watershed of Teupin Mane (Krueng Teumbo): 2008/2009 (18%), 2009/2010 (3%), 2010/2011 (1%), 2011/2012 (1%). For Sub Watershed of Lut Tawar (Wih Nareh): 2008/2009 (1%), 2009/2010 (1%), 2010/2011 (4%), 2011/2012 (1%). Estimates using the two methods define a reasonable range of the base flow contribution to stream flow in the watershed.

Abstract
Pesisir Selatan District is one of the areas in West Sumatra that often experiences natural disasters of landslides. Natural disasters of landslides that occur in this area often cause losses in the form of property or human lives and disruption of road access to other areas. The aims of this research were to analyze the hazard of landslides based on land characteristics, analyze the carrying capacity of the region based on landslide hazards, analyze social vulnerability, and analyze prediction of Population loss. The method used in this study is a survey method with a geomorphological approach. Data used in the form of primary data and secondary data. The technical analysis used is in the form of scoring to analyze landslide hazards and GIS used to analyze the carrying capacity of the region, vulnerability, and exposed populations. The results showed that the hazard of landslides in the study area was divided into three, namely low, medium, and high hazards. The hazard of low landslides is generally found in plain areas near the coast. This area is formed due to the results of sedimentation processes from both rivers and the sea. The hazard of moderate landslides is generally found in hilly areas, and the hazard of high landslides is generally found in hilly or mountainous areas. The hazard of landslides is caused by physical characteristics in the form of high rainfall, steep slopes to very steep slope, high rock weathering. Social vulnerability in the research area is divided into two parts, namely low and medium. Low social vulnerability is caused by the ratio of male population more than female population, ratio of vulnerable groups, ratio of poor Population, and a ratio of disabled Population. Social vulnerability is being caused by a greater number of female populations, ratios of vulnerable groups, and disabled Population. The prediction of population loss found in the Lakitan Tengah area is in Lengayang Subdistrict, which is 11,869 Population.

Published: August 2019

Abstract
Some parts of Bojonegoro Regency along the Bengawan Solo River experience flooding every year due to its downstream area. This leads to a drowning in the rice field areas for several months in the rainy season. As the consequence, the rice fields cannot function well in the agricultural cultivation process. One of the ways to adapt to this condition is cultivating floating rice. However, the further research on the social economic characteristics of the farmers in their accordance to the technological advancement needs to be conducted. This article aims to study the social economic characteristics of the farmers on the existence of the demonstration plots of floating rice cultivation. The method used in this research includes the demonstration plots and farmers survey. The surveyed respondents were 200 farmers living 3 km away from the demonstration plots. The findings show that the characteristics in which respondent farmers are dominated by unproductive ages, low education, low income, limited land tenure, and the lack of information shall be the obstacles in developing floating rice cultivation. This is due to the relatively high operational cost for making floating medium and caring plants different from others. The farmers’ mindset tendency to give up to the natural condition is difficult to change when adapting to flood conditions.

Experimental Research on the Stability behavior of Composite Curved Stiffened Fuselage Panel under Four-Point-Bending load
Authors: Hao C , Nan C Y , Bo Y Z , Lei L 
Published: August 2019

Abstract
In the design of fuselage structure, not only the longitudinal stability should be considered, but also the circumferential stability of fuselage structure is important because of its circumferential bearing of bending moment, shear force and axial force, as well as considering crash conditions. In this paper, the circumferential stability test researches of the fuselage structure were performed on the single-frame curved panel test specimens. The buckling and post-buckling characteristics of the single-frame curved panel under the negative bending condition were examined by four-point bending loading method. At the same time, the buckling mode, failure process and damage mechanism of single-frame curved panel were analysed through the load-strain curves of the skin and the different degree of damage of the three test specimens. The experimental results show that the buckling of skin is an important factor causing the debonding between the cap-stringers and the skin. The expansion of the debonding area greatly reduces the bearing capacity of the curved stiffened panel structure, which eventually leads to the breakage of the frame.

Published: August 2019

Abstract
The effect of trace Ca addition on corrosion resistance of ZA124 magnesium alloy was studied. The results showed that the effect of adding 0.3% Ca on the refinement of the microstructure of the alloy was obvious, in which the reticular transformation was fine and intermittent or strip-like, and no new phase was formed. With the addition of Ca, the corrosion rate and current density of the alloy in 3.5% NaCl solution decreased, which improved the corrosion resistance of the alloy. When the calcium content was 0.3%, the alloy had the best corrosion resistance.
