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 time to peak model is indispensable in determining the design of water infrastructure in Indonesia, given the many immeasurable watersheds that do not have rainfall and discharge data in determining the design in an area. The typical Indonesian peak time models that have been developed include Gama I, where several other Shyntetic Unit Hydrograph (SUH) still adopt models developed based on watersheds that are not in Indonesia. The Time Peak Model developed 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). watershed form factor (Fb), river branching factor (RB), river length factor (RL), and Fractal Dimension (DF). This parameter will be compared with the time peak obtained from the hydrograph calculation of the observation unit using the Collins method. To calculate the hydrograph, the observation unit requires rainfall and discharge data. Meanwhile, to obtain these parameter values, a topographic map, a Digital Elevation Model (DEM) map, and a land use map are needed as well as the help of ArcGIS, Hec-RAS, AutoCAD, and Microsoft Excel software. Rainfall analysis will be tested by RAPS, stationary test, and outlier test, while the discharge data is stationary test and outlier test. The results of research from 10 watersheds spread across Java and Sulawesi obtained peak time (Tp) 3-5 hours, peak discharge (Qp) 1.89-39.93 m3 / s, watershed area 40.62 - 1376.75 km2; length of the main river (L) 24.95-106.48 km; the length of the river from the center of gravity of the watershed to the outlet (Lc) 5.45 - 32.99 km; river slope (S) 0.004-0.138; Watershed roughness (n) 0.035-0.048; watershed form factor (Fb) 0.04-0.70; river branching factor (RB) 3.05-40.51; river length factor (RL) 2.47-6.74; Fractal Dimensions (DF) 0.94-1.85. The results showed that the parameter L had the highest correlation rate followed by parameters A, RL, Lc, RB, DF, S, n and
Each community or group has local wisdom that is different from one to another. This is because local wisdom was born driven by the needs of the group in interacting with its environment, the natural surroundings, the groups that interact with it, as well as with group members. Forms of local wisdom can be either material or immaterial in the form of patterns of action or cultural outcomes. This research will raise local wisdom from one of the community groups in Indonesia, namely the Riau Malay community with local wisdom in the form of oral literature, in this case, Pantun. Therefore, this study will discuss the Pantun of the Riau Malay community as one of the local wisdom in Indonesia.
