Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Digital Outcrop model (DOM) is a three-dimensional model produced through image/photo data processing, therefore, it tends to provide a precise picture of rock outcrops or geological features. The use of this method have been discussed in some studies, however, research on the analysis is yet to be statistically compared to direct measurement data in the field. This research was carried out on granitic basement rocks in the Indragiri River, Muaro Silokek, West Sumatra with an area of 510 m x 19 m. Data was obtained by comparing the fracture characteristics in DOM and five scanline-windows scan locations with dimensions of 500 cm x 200 cm. Based on the fracture orientation spread over the DOM, there are four domain segmentations with three main orientation directions namely NNW-SSE, NE-SW, and ENE-WSW which are part of the Takung Fault. The results showed that by statistically analyzing the scanline - windows scan data, the direction and dip of the shear fracture is relatively similar to the fracture analysis on the DOM, with a measurement difference of ± 8°
Metropolitan cities often face land subsidence problems due to natural and human factors, which are associated with tectonics, soil compaction, massive groundwater extraction and building loads. The uses of land have been limited due to the regulated city spatial plan in controlling the intensity and building heights maps. This study therefore aims to examine the efficiency of Regional Spatial Planning in controlling land subsidence. Data were obtained from the Spatial Plan and research sites in Kelapa Gading and Penjaringan Sub-districts, North Jakarta, by analyzing the overlay of land subsidence maps, groundwater extraction, land use, building height, and soil type. The results showed that the Jakarta Spatial Plan is an effective approach in reducing land subsidence by determining building heights according to the soil type, and by zoning the utilized land
The “S” Gas Field began production in 2015 which was distributed by 10 production wells from 3 clusters and would be develop with improve the facilities such as flowline & well connection. There are 3 Cluster to support 10 wells. Facility gas Development of Field “S” has been produced gas 310 MMscfd, 12,500 Bpd Condensate production design and 2,000 Bpd of produced water. Pipe flowline trunkline towards CPP, Central Processing Plant (CPP) facility with a capacity of 2 train x 155MMscfd, Gas Pipeline along 23 Km for transport sales gas and Condensate storage tank & loading Condensate jetty termina. Regarding the “S” Gas Field development phase-2, it requires optimization of Condensate products starting from the new well flow rate, Condensate formation process, Condensate component acquisition process, Condensate storage, Condensate pipeline process. The purpose of this research is to analyze the capacity of existing gas production, especially Condensate products through simulation, so that it can be known that the need for additional Condensate processing equipment until the required lifting is known. Thus, the additional investment from the development plan will be efficient. This study can be useful to make the design of Condensate production from two gas development scenarios. So that it will be known the suitability of the equipment that will be developed
This paper proposed a method to model the gait movement of four-legged amphibious robot. This type of robot has shown a great potential to perform complex operations in difficult and challenging land and underwater environments. Not only they can monitor and manipulate complicated environment conditions during disasters such as floods, landslides, and others, but it can also perform deep ocean exploration, underwater structures manipulation, disaster rescue operations, and reconnaissance. The promising advantages of amphibious underwater robots have motivated researchers to propose different design strategies for the structures and control methods of such vehicles. To design and model the four-legged amphibious robot, the connection between the input links with the output links was identified in this paper. The system architecture and system prototype were developed for model performance test. The tests were conducted and analyses using the SAM- the Ultimate Mechanism Designer for various configurations of the links in terms of the angle, angular velocity and the angular acceleration
Acid Mine Drainage (AMD) is a liquid waste caused by mining industrial activity. AMD has a very acidic pH and contain heavy metals, such as Fe and Mn. Therefore, the solution of this global problem should be investigated. One of the ways to treat AMD is by adsorption using activated carbon. Activated carbon is made from coals through chemical activation process using ZnCl2 with a composition of 40% ZnCl2 and 60% coals. Afterwards, carbonization process was performed at 500oC for 120 minutes. The synthesis result of activated carbon was analyzed for iodine numbers and characterized using BET. The activated carbon had maximum iodine numbers of 1373 mg/g and maximum surface area of 667 m2/g. Ion content in Fe and Mn in AMD was adsorbed using activated carbon with several variations of activated carbon grain size, mass, and contact duration. The results showed maximum adsorption of 100% for Fe and 56% for Mn, with increased maximum pH from 3 to 6.2. Kinetic and adsorption study was conducted on contact duration variation and obtained that adsorption process followed Langmuir isothermal model with adsorption capacity of 2.54 mg/g.
