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.

Asphalt cement is used as the main part of mixtures in pavement materials. It is necessary to know the physical and rheological properties to simulate the behavior of the asphalt binder. Rutting and pavements crack are the major distress of flexible pavement to enhance the properties of asphalt binder and to prolong the lifetime of roads must modify asphalt binder. The purpose of this paper is to analyze the physical and rheological properties where they are important parameters for predicting the efficiency of the asphalt binder. For the preparation of modified asphalt binders, asphalt (40-50) grade penetration from Daurah refinery has been used with two additives of bentonite (khawa clay) and crumb rubber; each additive has three percent (3 %, 6 %, and 9 %) of asphalt weight. To assess, the rheological properties used in numerous experiments involved the rotational viscometer (RV) at two temperatures of 135℃ ,165℃ , the dynamic shear rheometer (DSR) for the asphalt binder. The physical properties were tested via several conventional methods, such as penetration, ductility, and softening point tests. Also, a thin-film oven test to study the aging of original and modified asphalt pavement. The optimum content of the modifiers was 6% crumb rubber and 9% bentonite. From the result can conclude that the addition of bentonite and crumb rubber enhance asphalt properties such as increase the viscosity, ductility, and softening point, decrease penetration Compared to original asphalt, based on the results of rheological tests, the performance grade (PG) of original asphalt binder was PG64-16, and the performance degree for Bentonite modified Asphalt binder was PD70-16 and crumb rubber modified Asphalt binder was PD76-16.
Durian seed flour is a source of carbohydrates that has the potential to be used to meet the carbohydrate needs of Type 2 Diabetes Mellitus (DMT-2) sufferers, but before it is used to fulfill carbohydrate needs in diabetes sufferers, an in vivo test is needed to identify the glycemic index (GI) of the flour. This study aims to determine the glycemic index of durian seed flour given orally to Sprague Dawley rats. This research was arranged in 2 steps, namely the manufacture of durian seeds flour and the glycemic index test with 5 repetitions with time variations 0; 30; 60; and 120 minutes at 3 days intervals using a glucometer. Rats were grouped into 3 groups each consisting of 2 rats. Flour was suspended in 0.1% sodium carboxymethyl cellulose (Na-CMC) at a dose of 0.5625 g, positive control was 1.125 g of glucose that given in an oral way. Data in the form of test animal blood glucose levels versus time were analyzed into the Area Under Curve (AUC) glucose levels versus AUC. GI calculations were carried out by comparing the AUC of durian seed flour to glucose AUC. The results of the research and calculations carried out obtained the GI of durian seed flour of 10.90 with low criteria category. With this GI value, it can be stated that durian seed flour has the potential as a source of carbohydrates for DMT-2 sufferers.
