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 volcanic area is blessed with a lot of resources and cursed with eruptive disaster at the same time. Fertile land, deep forest, mining deposit, and water reserve are examples of the potential within a volcanic environment. The more productive activity is taking place, the more it risks damaged by a disaster. In 2010, Merapi, an energetic volcano in Java – Indonesia, erupted on a massive scale equal to one event in one hundred and seventy years. It was estimated up to 140 million m3 lahars produced, overwhelming installed sabo dams with only 20 million m3 in capacity. It damaged these sabo dams severely. Meanwhile, damaged sabo dams urgently needs to be either rehabilitated or reconstructed to set preparation against the next incoming eruption. This paper would focus on the estimation of functional performance given by the sabo dam at present actual condition. The aim is to create modelling framework base on structural equation modelling (SEM). It adopts water resources principles, recent developed model, regulations and factors that influencing this purpose. All governing factors are grouped into three major classifications, i.e. physical aspect, regulative aspect and social aspect. Output will be governing aspects proportion of weight in assessing actual performance. The model will be useful to value sabo dam conditions in the framework of rehabilitation and reconstruction planning where a limited budget is present
Nakayasu synthetic unit hydrograph is one method that is widely used in the analysis of design flood discharge in Indonesia. The Nakayasu synthetic unit hydrograph method requires relatively little data and the results still need to be tested in order to fit the reality. Following the various studies related to α parameter that have been carried out, these parameters are still not optimal and only valid in certain locations, so the formulation is needed to determine the value of α parameter which is adjusted to the physical watershed characteristics in Java. This research aims to develop a model α parameter that is related to the characteristics of the watershed in Java. The physical parameters of the watershed are shape factor (E), watershed slope (S), the distance from the outlet to a point on the stream nearest the centroid of the watershed area (T), watershed length (I), perimeter (W) and watershed area (A). The α parameter developed is generated from statistical analysis for several watershed characteristic variables that have a significant effect. The results of the model development α parameter are with R2 = 0.8768 and R = 0.9364
