Published: October 2019

In some areas, compacted clay liner is chosen as leachate barrier for solid waste landfill. Due to the typical shape of the landfill, the compacted clay liner will be rested both in flat and sloping ground. Since clay has characteristics of low shear strength, improvement of shear stability of compacted clay liner is required. One of the stability methods to increase the shear strength of clay is by adding another material which has higher shear stability. In this study, bentonite is used to represent clay liner while zeolite is utilized as stabilizer material. Four compositions of bentonite with 0%, 5%, 10%, 15% addition of zeolite were prepared to investigate the stability performance of the mixtures. The results indicate that the addition of zeolite into bentonite has increased the friction angle of the bentonite. However, the addition of zeolite seems to alter the hydraulic performance of bentonite. The highest permeability is demonstrated by the bentonite with 15% of zeolite. Whether the permeability increases, the hydraulic performance of all the mixtures are still met the maximum permeability allowed for landfill liner.

Published: October 2019

In recent years, Tourism activities in Gunungkidul Coastal Area rapidly increased. A large number of tourists visiting the coast considered as elements at risk that are exposed to tsunami hazards. Disaster infrastructures provided by the government e.g. hazard maps, evacuation routes, and locations for assembly points are inadequate. The tsunami inundation models provided by the government are based on national topographic maps (RBI), resulting in inaccurate models. DEM generation using UAV Photogrammetry produces high spatial resolution data that results in more accurate tsunami inundation model. The results of the model using UAV photogrammetry are also capable of producing several inundation scenarios and determine the safe areas that can be used for temporary evacuation sites. The use of UAV photogrammetry for tsunami inundation models provides many advantages including low cost and accurate model results. Evaluation of hazard maps and assembly points using UAV Photogrammetry modeling lead to more effective and less time-consuming on the evacuation process.

Authors: Subiyanto Agus , Nurhayati  , Allien Astri Adriani
Published: October 2019

Traditional fishermen in the North Coast of Central Java commonly have a simple life economically, and their income is sometimes sufficient only for fulfilling their very basic needs, especially food. However, their social life and environment are worth appreciating. The tough life in the sea has taught them how to behave with others. They believe that the sea is inhabited by many supernatural creatures, and so they have to avoid doing improper behavior as reflected in seafaring myths. This paper aims to discuss the kinds of seafaring myths related to forbidden acts among fishermen in the North Coast of Central Java, and the factors causing their belief of the myths. In this case, an eco-linguistics perspective is used to uncover the phenomena of the seafaring myths. This study used the data taken from interviewing fishermen, randomly chosen as the informants, who live in fishing areas in Semarang, Kendal, and Demak. The result of the study shows that seafaring myths still exist, and they are preserved because of the empirical facts they often experience when violating the myths. From an eco-linguistic perspective, the existence of the myths cannot be separated from biological, sociological, and ideological aspects of the fishermen.

Authors: Djayanti Silvy
Published: October 2019

Energy resources are gradually scarce and expensive. Raised a gap between increasing demand and energy supply. Bridging gap of demand together with energy supply by increase energy supplies is a very costly decision. Moreover, in the industrial sector with the high cost of energy, the longer the competitiveness decreases. Energy costs in total production costs reduce the number of profits each year. The strategy to prevent these problems is by increasing the efficiency of industrial operations and equipment. Several stages of the efficiency process begin with identifying balance, energy-saving opportunities, and energy utilization. This stage is better known as an energy audit. The advanced stage of the energy audit helps identify potential energy conservation and encourages the industry to focus on efficiency and conservation and is supported by adequate financing. In the research strategy, the opportunity to save energy costs in oil boiler units is practical, sustainable and economically feasible. On the results of measurements and calculations obtained boiler efficiency of 53.67% where the factors that cause the low efficiency of this boiler are the high excess water by 17.32% and heat loss from dry exhaust gas by 42.03%. The solution is done by controlling excess air by regulating the air entering the combustion chamber. In this way, energy savings can be increased by 15%.

The government has budgeted assistance/grants continuously many bed dryers to farmers but many of them were not used because farmers felt that the drying production rate of rice is more expensive than the traditional open sun drying. The farmers choose to go back to the traditional way that takes the drying process longer than using the dryer. For 1 year, open sun drying can process 100 batches, and dryer can process 450 batches. This research tries to solve the high cost problem by looking for a new alternative solution. The solution is replacing the oil burner with a rice husk burner, which is appropriate both economically and environmentally. For the stirring mechanism, this system must continuously stir up the pile of grains during the drying process. The point must be fulfilled is that the total cost of the drying process should not rise, especially the cost of the stirring process. A stirrer mechanism that needs smaller power than the maximum power setting is made. Farmers’ income for this innovative modification will get a 332% increasing profit than using oil burner bed dryer machine and will get a 41% increasing in welfare than using the standard husk burner bed dryer.

Electrical energy is produced by objects that are electrically charged. Static electric charges will cause electrical potential energy, while dynamic electric charges will cause electric current and magnetic energy. The size of the population and the diversity of activities in metropolitan cities in Indonesia have resulted in general problems in urban infrastructure services, such as current waste problems. Waste is defined as solid waste consisting of organic substances which are considered useless and must be managed so as not to endanger the environment and protect development investment. Landfill gas is a gas produced by solid waste which is disposed of in landfills. The waste is piled up and pressed mechanically and the pressure from the layer above it. Because the condition becomes anaerobic, the organic matter decomposes and gas landfill is produced. This gas is increasingly gathering to be slowly released into the atmosphere and if it is not used or handled properly it will be dangerous because it can pollute the air and the atmosphere of the earth. The largest gas content found in LFG is methane by 45 - 60% and followed by carbon dioxide by 25-50%. Landfill gas is produced from the decomposition of organic waste material.

With the development of technology, the need for electricity is increasing. In terms of Indonesia's topology, the Solar Power Plant is most suitable for use in rural (remote) areas, known as the Solar Home System (SHS). This system is preferred because it is small in scale and uses a direct current (DC) system. This system can reduce costs because it does not use an inverter. But the weakness of this system is the difficulty of finding home electronic equipment such as TV, Radio / Tape and others that use DC, so the SHS system is not attractive to use. PLTS connected to PLN's electricity network, Interactive Grid, BIPV (Building Integration PV) is a hybrid application between the electricity network (PLN) and PLTS that are already widely used. Thus, PV-Genset Hybrids can reduce the inefficiency of operations and maintenance and reduce large initial investment costs

The subsurface pressure analysis is used to detect the overpressure and problems in the well that will be drilled based on exploration well data. Various problems were found while drilling operations carried out on A and B wells, namely, Kick and Pipe sticking which cause a high Non-Productive Time (NPT). This research is conducted to identify the mechanism of overpressure formation in Tight Sand Gas and Shale Gas in the Jambi Sub-Basin. Furthermore, to predict pore pressure using the Drilling Efficiency and Mechanical Specific Energy (DEMSE) and Bowers method. The final result will be a 3D pore pressure cube in the area based on quantitative analysis of post-stack seismic inversion. The results of the pore pressure analysis from the wells and the 3D pore pressure model indicate that top of overpressure occurs in the Gumai Formation, then it is decreasing gradually approaching the hydrostatic pressure on the Basement. The mechanisms of overpressure are caused by under compaction, fluid expansion (kerogen maturation). The Gumai Formation and Talang Akar Formation are shale rocks so the type of mud weight that is well used is oil based mud (OBM).
