Design for manufacturing and assembly (DFMA) is widely applied in many industries to optimize the manufacturing and assembly process at the early stage of design, with the aides of the CAD model. Many researchers apply the DFMA to increase assembly efficiency, by decreasing the number of parts from a product, decreasing the manufacturing cost, and reducing assembly time. Therefore, this research applies DFMA to develop exhaust fan housing with ceiling mounting for high rise building type with the same purpose, and at the same time to justify that the method can overcome the problem of assembly time in a production line. Both designs from before and after the application of DFMA, are being compared by using finite element simulation and experimental. The simulation employs stress analysis, to predict the strength of those designs. While the experimental uses a manufacturing cost survey, real assembly time survey and failure test to show the advantages of DFMA design results. The research result shows that the DFMA method can decrease the manufacturing cost by 0.44%, and the assembly time by up to 2%, and able to withstand the entire mass of the ceiling mounting fan.

Forecasting load is an integral part of the planning, operation, and control of power systems. This paper is part of a research effort aimed at developing better energy demand forecasting models for load dispatch centers (LDCs) in Indian states as part of an ambitious project utilizing artificial intelligence-based load forecasting models. In this paper, we present a half hourly load forecasting method for the energy management system of the project that will be used at 33 /11 kV and 0.415 kV substations with good accuracy. The paper uses the half-hourly load consumption dataset collected from MSEDCL for Maharashtra from July 1, 2020 through August 31, 2022. This paper evaluates 24 regression model-based half hourly based load forecasting algorithms for ALE PHATA load based on the load consumption dataset and the collected meteorological dataset. The 24 models in MATLAB Regression belong to five types of regression models: Linear Regression, Regression Trees, Support Vector Machines (SVM), Gaussian Process Regression (GPR), Ensemble of Trees, and Neural Networks. As a consequence of their nonparametric kernel-based probabilistic nature, the GPR family of models demonstrates the best load forecasting performance. Least squares estimation was used to determine the regression coefficients. There is a direct correlation between load in an electrical power system and temperature, due point, and seasons, as well as a correlation between load and previous load consumption. Therefore, the input variables are Wet Bulb Temperature at 2 Meters (C), Dew/Frost Point at 2 Meters (C), Temperature at 2 Meters (C), Relative Humidity at 2 Meters (%), Specific Humidity at 2 Meters (g/kg) and Wind Speed at 10 Meters (m/s). The mean absolute percentage error and the R squared are used to validate or verify the accuracy of the model, which is shown in the results section. Based on this study, two GPR models are recommended for load forecasting, the Rational Quadratic GPR and the Exponential GPR and Exponential GPR as final model.

This study aimed to look at madrasah's efforts in developing a learning system through "digital learning." This was done by examining the digital learning system implemented at MAN in terms of its advantages and disadvantages. The method used in this research was descriptive qualitative, with the data collection techniques employed were direct observation and interviews. Meanwhile, the research location is four MAN in Jakarta and Tangerang area, including. The four madrasahs that became the research locations were MAN Insan Cendekia Serpong (South Tangerang), MAN 1 Tangerang, MAN 4 Jakarta, and MAN 13 Jakarta. The researcher conducted interviews with school parties, namely teachers and principals. The results showed that three madrasahs have well-managed e-learning systems. In this case, they are MAN IC Serpong, MAN 1 Tangerang, and MAN 4 Jakarta. The e-learning system used by each madrasah is E-Learning Madrasah which can be accessed using the web and applications from Play Store. Meanwhile, MAN 13 Jakarta still needs to have its e-learning system and use standard features such as zoom, G-meet, etc. Basically. Madrasahs such as MAN IC Serpong, MAN 4 Jakarta, and MAN 1 Tangerang have registered to utilize the digital learning platform with all the features provided. Meanwhile, MAN 13 Jakarta has yet to register, so it cannot utilize the features contained in the digital learning platform. This research implies that madrasahs have innovated well in digital learning implementation so that learning during the pandemic can run well and smoothly. This research further contributes theoretically and practically to the world of education, especially for madrasas regarded as "second-class" schools. In general, this research contributes to the development of the world of digital learning by providing a valuable platform through the various features provided
这项研究旨在考察伊斯兰学校通过“数字学习”开发学习系统的努力。这是通过检查在MAN实施的数字学习系统的优点和缺点来完成的。本研究采用描述性定性方法，数据收集采用直接观察和访谈方法。同时，研究地点是雅加达和丹格朗地区的四个MAN，包括。成为研究地点的四所伊斯兰学校是MAN Insan Cendekia Serpong(南丹格朗)、MAN 1 Tangerang、MAN 4 Jakarta和MAN 13 Jakarta。研究者对学校当事人，即教师和校长进行了访谈。结果显示，三所伊斯兰学校拥有管理良好的电子学习系统。在这种情况下，他们是MAN i Serpong, MAN 1 Tangerang和MAN 4 Jakarta。每个伊斯兰学校使用的电子学习系统是电子学习伊斯兰学校，可以使用网络和Play商店的应用程序访问。同时，MAN 13 Jakarta仍然需要拥有自己的电子学习系统，并使用zoom、G-meet等标准功能。基本上。manic Serpong, man4 Jakarta和man1 Tangerang等伊斯兰学校已经注册使用具有所有功能的数字学习平台。与此同时，MAN 13雅加达尚未注册，因此无法利用数字学习平台所包含的功能。这项研究表明，伊斯兰学校在数字化学习实施方面进行了很好的创新，因此大流行期间的学习可以顺利进行。这项研究在理论和实践上进一步为教育界，特别是被视为“二等”学校的伊斯兰学校做出了贡献。总的来说，本研究通过提供的各种功能提供了一个有价值的平台，有助于数字学习世界的发展

The main problem of transportation is the very high growth of vehicles causing congestion, resulting in various derivative impacts such as pollution, fuel waste, time value, and other environmental problems. This problem can be solved by Transportation Demand Management (TDM). TDM is a combination of various strategies, which strategy should be chosen whose priority depends on the conditions of each region. This research was conducted in a medium-scale city by determining the priority of TDM using the Analytical Hierarchy Process (AHP) tool. The final result of the judgment is the priority weight of the TDM strategy that will be applied with a CR value of < 10%, namely the pull strategy. This strategy is represented by improving public transport services and infrastructure (especially the integration of public transport services). This study shows that the strategy group with a high AHP Consensus Index (ACI) score means a high consensus among experts.

Digital technology is currently highly developed in all fields. The development of this technology certainly has a big impact on the world of business and industry. This study tries to prove the effect of instrument readiness in developing technopreneurship abilities in students. The readiness instrument variables used are Capital Thourgh, Information and Social Network. The study was conducted on 150 students who have technology-based businesses (technopreneurs) as samples. The data analysis technique used is the structural equation model with the help of Smart PLS. The results showed that Capital Through did not have a significant effect on technopreneurship, but Information and Social Networks had a positive influence on technopreneurship. In addition, the Social Network is able to encourage a technopreneur to make it easier to obtain information related to business development.
