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.

The synthetic unit hydrograph method is a popular method for analyzing watershed flood discharge for rivers that do not have observational flood hydrographs. To create flood hydrographs for rivers with no or very few observed flood hydrographs, it is necessary to require data on characteristics or parameters of watershed areas (DAS). The Time to peak Model in this study will consider several parameters including the area of the watershed (A), the length of the main river (L), the length of the river from the center of the watershed to the outlet (Lc), river slope (S), watershed roughness (n), factor the shape of the watershed (Fb), as well as the fractal characteristics of the watershed in the form of river branching ratio (RB) and river length ratio (RL). To get the accuracy of the time to peak model and to get a flood hydrograph that can represent the prototype, it is necessary to do some statistical analysis. The time to peak model predicted using linear regression analysis produced the time to peak equation (Tp) as a function of watershed area (A) and river length from the center of the watershed to outlet (Lc). This equation has a good level of accuracy with a correlation coefficient of 0.893; The coefficient of determination is around 0.797 and Adjusted R2 is around 0.746. The model has also met the requirements of the classical assumptions including linearity test, residual normal test, heteroscedasticity test, autocorrelation test (indicated by the Durbin Watson value of 1.895 with the interpretation of no autocorrelation) and multicollinearity test. Model validation has NSE value of 0.731 (good), RMSE value of 0.482 and MAE value of 0.390 (both RMSE and MAE values are close to zero). Model verification has NSE value of 0.758 (very good), RMSE value of 0.394 and an MAE value of 0.320 (both RMSE and MAE values are close to zero).
Magneto telluric, Gravity, and Passive Seismic Tomography (PST) surveys were conducted over the southwestern part of Central Java, Indonesia. The thick volcanic sediments conceal the prospective sedimentary basin in the area, which has been researched for more than five decades without any significant results. New evidence of the tecto-volcano system in the study area was found based on the methods. The study reveals two major geological structures in the area. The northeast-southwest lineaments, which correspond to the Meratus Thrust-Folds were strike-slip faulted by the Pamanukan-Cilacap Fault Zone (PCFZ) in the northwest-southeast directions. The Meratus Thrust-Folds existence proved that the study area is related to the Paleogene Fore-Arc Basin. However, the Meratus Thrust-Folds has been vanished partially due to the volcanism activities. Superimposed calderas of the ancient-volcanoes system were distinct in the area. The circular patterns which are interpreted as the part of ring-fault are found based on the Gravity dataset as well as the geomorphology and geological formation. The old magmatic chamber and the volcano conduit system within the calderas have been modeled based on the Magneto telluric dataset and confirmed with the PST interpretations. The interpretation is constrained by the existing exploration well. Two eruption points delineated following the high-resistive zones of the Magneto telluric dataset, while another eruption points are estimated based on circular patterns. All of the eruption points are located at around PCFZ as the weak zone, where the plume passes through and rising the volcanoes.
This study aims at measuring the level of municipal services quality and citizen’s satisfaction in Jenin Area. Obviously, the study problem shows that the citizens are not satisfied with the current services quality offered by the municipalities in the Governorate of Jenin. Hence, this paper is considered as a base-stone for the municipalities of Jenin area in which academic researchers at institutes and universities can get use of its findings and recommendations. The study population comprises citizens who reside in Jenin area. Whereas, the study sample is made up of (400) respondents of the surveyed municipalities. The study findings reveal that the citizens are satisfied with the Service Quality offered by the municipalities in Jenin area. The findings also show that citizens' evaluation of the quality of the municipal services is positive for each of the five dimensions of Service Quality (tangibles, assurance, responsiveness, reliability, empathy). As a consequence, the aforementioned findings of this paper come up with a number of recommendations. However, the most significant recommendation states that the municipalities in Jenin area should adopt the findings of this paper especially the positive evaluation of the Service Quality. This positive evaluation reflects the satisfaction of the citizens, which leads the working municipalities in Jenin area to offer better services.
This study was aimed to apply the powder of sea cucumber (Holothuria scabra) in the formulation of composite sago based biscuits. The sea cucumber was processed through smoking, drying, and grinding to make a powder. Biscuits were made by mixing that powder with other ingredients. The formulations of the biscuits dough applied were T0 (100% wheat) as a control, T1 (50% wheat, 40% sago, 10% sea cucumber), T2 (50% wheat, 35% sago, 15% sea cucumber), T3 (50% wheat, 30% sago, 20% sea cucumber), and T4 (50% wheat, 25% sago, 25% sea cucumber). The product obtained was then measured its sensory properties and antioxidant activity. Other characteristics tested were their chemical content, and morphological properties with Scanning Electron Microscope (SEM). The results showed that the formulation of T1 gave a relatively best sensory characteristic. Meanwhile, protein, fat, minerals, and antioxidant activity were increased as the percentage of sea cucumber powder substitution was increased. The morphological appearance of the products indicated that sea cucumber powder was evenly mixed with other ingredients in the formulation. The inclusion of sea cucumber in the formulation of processed food products had improved the nutritional and functional values of the food, and it may improve its added value.
This paper presents the field result evaluation on the effectiveness of grouting method foundation improvement on the Tugu Dam to the Lugeon value. The geology of Tugu Dan consists of alluvial-collovial. The evaluation is carried out in the dam foundation on the 0-50 m depth. The implementation of grouting is divided into three parts that are blanket, sub-curtain, and grouting.
