This research examines the dynamic load resistance of the Giromill type wind turbine to the variable wind speed, which is converted to the value of the force received by the wind turbine blades. The analysis was carried out numerically using Autodesk Inventor Professional 2019 software. The variations in wind speed used were 2.5 m/s with a force value of 0.195 N for the Giromill turbine, at a speed of 3.5 m/s with a force value of 0.274 N, at 4.5 m /s with a Force value of 0.352 N and a wind speed of 5.5 m/s with a force rating of 0.430 N. From the simulation results using the Autodesk Inventor Pro 2019 software, the effect of gravitational force is greater than the wind force in, so stress analysis is mainly caused by gravity while the wind force has no significant impact. The simulation results also have a characteristic that the higher the wind speed, the lower the stress value. In addition to the dynamic load simulation, the author also tries to implement the Giromill wind turbines in Muara Enim district, South Sumatra, Indonesia. The wind turbine blade rotation will be faster, and the Wind Generator will produce a greater voltage if it is supported by sufficient wind speed.

Madrasah is a place of study or formal school equivalent to elementary school, but at madrasah there will be more to learn about Islam, especially learning to read the Koran. Madrasah Ibtidaiyah (MI) Kintap uses the at-tanzil method in the process of learning the Qur'an, with the aim that students can understand more quickly about tajwid and the law of reading the Quran. MI Darul Ulum Kintap will provide a notebook of the achievements of the students so that parents can monitor the extent to which the students have learned. The problem that exists in recording the student's achievement using a note book is the negligence of the students in maintaining the achievement record book, so that it can make it difficult for parents and teachers to monitor the learning process of the students. To overcome this problem, the authors take advantage of technological developments by building a system that can be used to access data on student achievement in real time. This research also adds a feature to register new students, so that parents can register their children online. In this research, data analysis uses the method waterfall. The results of the research that has been carried out are that all features or functions of the system built have run well according to their function by testing the functionality of the system using the method black-box.

Biodiesel is a biomass fuel that can replace petroleum diesel fuel. One of the advantages of biodiesel fuel as renewable energy source that it is more environmentally friendly than fossil fuels because biodiesel significantly reduces greenhouse gas emissions compared to fossil fuels. FAME (fatty acid methyl ester) is a derivative product of CPO (crude palm oil) that has been treated both physically and chemically. The main advantage of FAME lies in the low content of impurities, especially sulphure and metal content. FAME comes from vegetable oil raw materials, which contain high enough fatty acids, around 61-62%, and nowadays, it is used as a mixture with petroleum diesel. The characteristics of biodiesel obtained from the conversion of FAME into biodiesel by pyrolysis at a temperature range of 160 – 200 oC indicate that the biodiesel produced is density 0.8475 kg/m3, viscosity 3.053 cSt, calculated cetane index (CCI) 48.5, flash point 59oC, moisture content 223 ppm, and sulphure content of 0.07% m/m. The results obtained are below the maximum limit of the specified biodiesel quality requirements.

Underground Coal Gasification (UCG) is a process of converting coal in the ground into synthetic gas that has economic value. In the UCG process which will be carried out in the UCG prototype assisted by the presence of oxygen as a gasification agent, which this gasification agent will help the process of burning coal in the ground. The flow rate of oxygen in the process of UCG affecting the coal combustion temperature and effective flame from burning coal. The highest temperature at a flow rate of 5 l/min is 240oC, at an oxygen flow rate of 3 l/min the highest temperature is 143oC and at an oxygen flow rate of 2 l/min the highest temperature is 135oC and time effective flame at a flow rate of 5 l / min ie 80 minutes, effective burning time on the speed of the flow rate of 3 l / min ie for 120 minutes and time effective flame at a flow rate of 2 l / min ie for 165 minutes. This study proves that the greater the oxygen flow rate is used as the gasification agent at UCG process the lignite coal combustion temperatures will be high and effective flame coal combustion process will be more brief.

International Journal of Research in Vocational Studies (IJRVOCAS) Vol. 1 No. 3 (2021): IJRVOCAS - December
Publisher : Yayasan Ghalih Pelopor Pendidikan (Ghalih Foundation)

Pesantren Nurul Muhibbin Tanah Laut, which is classified as a new Islamic boarding school, was founded in 2018, and as such, it requires significant input and assistance in resolving issues, particularly those relating to financial management and accounting information systems. If an error is made, not only social sanctions are imposed, but also legal sanctions; this must be a bright spot in the pesantren's financial management. This research employs a qualitative approach in the hope of identifying financial phenomena that can be used as material for joint evaluation. The study examines financial planning, implementation, supervision, and reporting phenomena. This financial process will be visualized as a flowchart in the hope that the relationship between the various components is obvious. Several of the findings in this study indicate that financial planning has been successful in terms of implementing a priority scale, deliberatively forming APBPP, and developing plans to strengthen pesantren financial management. The implementation process has not perfectly implemented the principle of accountability and generally continues to make ineffective cash payments, the supervisory process continues to violate the principles of organizational adjustment and responsibility, and the management accounting process and reporting continue to have numerous shortcomings, such as conventional accounting processes and the use of accrual accounting. The pesantren currently lacks a flow chart that adequately depicts the financial management process.
