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.

In this work, ANSYS WORKBENCH finite element analysis is used to construct and solve the problems related with the surface crack in round bars under combined bending and torsion moments. The solutions of stress intensity factors under combined loading are then compared with the results combined explicitly from the individual loading. Based on the observations, the pattern of all stress intensity factor is symmetrical and there are some discrepancies between both results as maximum as 4% where the combined stress intensity factors obtained directly from finite element analysis is always higher than the stress intensity factors obtained explicitly. However, for the case of area close to the outer surface, the stress intensity factors from both methods are well agreed to each other
This study aims to examine the ability of natural essential oils extracting from plants to control stem rot disease. The experiment was conducted at the Balittro, from July to November 2017, using a randomized block design consisting of seven treatments with four replicates. The plot size was 2 x 2 m and planted with peanut of local variety (Payo, Solok City) 9 plant: 1) JAI1: Cinnamon leaf oil (Cinnamomum burmanii) spraying once week, 2.) JAI2: spraying cinnamon leaves once every two weeks, 3). JBI1: bamboo piper oil (Piper aduncum) spraying once a week, 4). JBI2: weekly spraying of bamboo piper oil, 5). JCI1: citronella oil (Androphogon nardus) spraying once a week, 6). JCI2: citronella oil is spraying once every two weeks and 7). J0: without fungicides (controls). The formulated essential oil distillated from cinnamon leaves, bamboo piper and citronella were sprayed every week or two weeks, with dosage 3000 ppm. Parameters observed including the percentage and intensity of disease attack observed for six times. Observation of agronomic parameters included plant height and number of branches, pod number, weight per clump and weight 100 seeds. The results showed that botanical fungicide essential oils of citronella and bamboo piper have a higher ability compared to cinnamon leaf in controlling stem rot disease of peanuts (84.85% and 65.65%). Vegetative growth of peanuts treated with, essential oils of citronella, bamboo piper is better than cinnamon leaves and without fungicides. The amount of peanut fruit weight, weight per clump and weight of 100 seeds was significantly higher (51.74 g) than the fungicide treatment of essential oils of citronella oil and bamboo piper oil. The implication of the study is botanical fungicide derived from citronella and bamboo piper offered an environmentally sound solution to overcome the attack of stem rot disease in peanuts plants
