Abstract

West Pasaman Regency is one of the regencies in West Sumatra that experiences flooding the most. In 2020, in April and September, floods occurred in the West Pasaman district, more precisely around the Nagari Ujung Gading area, Lembah Melintang District. Floods most often inundate the Jorong Lombok and Jorong Irian areas. The flood that occurred was caused by the overflow of the Batang Bayang river. Puddles of water inundated at least 150 residents' houses until the water level reached a height of 1 meter. The problem of flooding almost every year is felt by residents who live near the location of the Batang Bayang river. This study aims to determine the flood discharge of the Batang Bayang river with return periods of 2, 5, 10 and 25 years. Then this study also aims to determine the ability of the Bayang Bayang River to flow flood discharge for 2, 5, 10 and 25 years return periods. The results show that the 2-year return period produces a maximum flood discharge of 47.2 m/s3. In the 5-year return period it produces a flood discharge of 110 m/s3, in the 10-year return period it produces a flood discharge of 143.6 m/s3 and at the return period of 25 years resulted in a flood discharge of 189.2 m3/s. The cross section modeling in the 2 year return period resulted in a water elevation of 21.07 meters. The 5-year return period modeling results in a water level elevation of 22.4 meters. The 10-year return period models the water at an elevation of 23.01 meters and the 25-year return period produces a water level of 23.72 meters.

Abstract

Air pollution is one of the most dangerous and worrying. One of the causes of air pollution is dust or Total Suspended Particulate (TSP), namely particles with a diameter of <100 μm. The Total Suspended Particulate causes visual distrurbances and respiratory disorders such as URTI (Upper Respiratory Tract Infection). According to data from Badan Pusat Statistik Kota Padang in 2018, URTI represents the highest complaint in the district Lubuk Begalung as many as 5,534 cases (28%). In the district has industrial and transportation activities which are a source of air pollution. However, in there haven’t real time monitoring of air pollution, so it is necessary to carry out air pollution simulations. This study aims to determine the concentration of TSP ambient air pollution and to analyze the distribution air pollutant in the Lubuk Begalung District, Padang City. The research method used a quantitative, where the emission inventory and meteorological data used the Gauss dispersion model and surver 15 software. The maximum TSP from measurement and modeling results was 113.42 µg/m3 and 27.16 µg/m3. This result explain about the TSP concentration is still below the National BMUA in PP RI No. 41 of 1999, which is 230 µg/m3 (still in good condition). This is different from previous studies because this study only considers sources of industrial emissions without other sources of pollution. The result of the TSP distribution is moving increasingly towards the Southwest from the emission source and reaches a maximum concentration at the coordinate point (-0.98103 oS, 100.34567 oE), according to the dominant wind direction.

Abstract

Effective energy conservation strategies are required to be implemented in academic buildings as they consume significant energy while considering the convenience and function of the buildings. However, the influencing factors are interrelated and complex, requiring an appropriate approach to unravel the complexity. Therefore, this study aims to identify, analyse, and map the interaction relationship between factors affecting energy conservation in academic buildings. This study used Interpretive Structural Modeling (ISM) procedure starting from developing the Structural Self Interaction Matrix (SSIM), converting SSIM into a Reachability Matrix, revising the matrix, and categorizing the factors by using MICMAC analysis. This study involved 9 factors, including architectural design, illumination technology, education and awareness, energy monitoring and management, renewable energy use, efficient HVAC system, energy-saving equipment, institutional policies, and campus community participation. The study found that renewable energy use at level 3 was the factor that was not influenced by and did not interact with any other factors. Meanwhile, the illumination technology was a factor that interacted with the efficient HVAC System factor which was at level 1 where these two factors were influenced by other seven factors. This study aligns with current developments in energy conservation, including an increased focus on renewable energy and energy efficiency in academic buildings, supported by global and national policies aimed at achieving sustainability goals. It provides a comprehensive understanding on developing sustainable energy conservation strategies in academic buildings.

Abstract

Processing rice products into rice requires further processing, where the grain harvested from farmers is processed into rice. The Nagari Binaan Community Service team from Padang State University will later develop this process. Farmer groups say that the availability of continuous and cheap electricity is their obstacle in producing good and cheap rice products. Counseling and assistance in making civil buildings capture turbulence water micro-hydro power plants is a solution to partner problems offered by the community service team of the Nagari program assisted by Padang State University. The output of the Nagari Fostered Program will be used to build a 5000-watt capacity power plant, supporting the need for free and environmentally friendly electricity. This aligns with the government's renewable energy program for 2030, which aims to produce 25% of the national electricity from renewable sources. This program is planned for 3 (three) stages, where the first year is mapping and detailed engineering design in the form of reports and design drawings. The second year is in the form of civil construction, and the third year's target is the installation of electrical machines and panels for commissioning. There will be training for partners, such as farmers in Kanagarian Kamang Hilia, Agam.

Abstract

Entrepreneurship is increasingly seen as an important strategy in reducing unemployment among college graduates and promoting economic resilience. This study aims to examine the predictive role of self-efficacy an individual's belief in their ability to complete a specific task in shaping entrepreneurial interest among university students. Self-efficacy is believed to influence how individuals perceive opportunities and challenges in starting a business, thereby playing a central role in entrepreneurial motivation. A descriptive quantitative approach was used in this study, with data collected through a structured questionnaire distributed to 348 students from nine faculties at the University of Padang. The questionnaire was designed using a Likert scale to measure levels of self-efficacy and interest in entrepreneurship. Data analysis was conducted using descriptive tests, normality, linearity, homogeneity, and hypothesis testing using Pearson's correlation. The results of the study showed a positive and significant relationship between self-efficacy and entrepreneurial interest (significance value= 0.012), with a Pearson correlation coefficient of 0.113, indicating a moderate relationship. Most students demonstrated relatively low levels of self-efficacy and interest in entrepreneurship, but students with high self-efficacy tended to have greater interest in entrepreneurship. These findings emphasize the importance of integrating self-confidence building into university entrepreneurship programs to enhance students' readiness and motivation to enter the entrepreneurial world after graduation.
