Evaluation of the performance of roof covering materials on building energy savings

Azwan Aziz

The roof as a covering component of a house, especially in tropical areas, is the surface of the building that is most exposed to solar radiation. Therefore, its role must be optimized in blocking solar heat radiation so that thermal comfort in the room below can be achieved. For this reason, choosing the right roof covering material and construction is important in optimizing its role in containing and transporting heat. The research method used is quantitative. This is because this research involves a lot of roof performance calculations regarding heat transfer values, namely RTTV (Roof Thermal Transmittance Value), and radiation calculations. The buildings studied were selected to use roofs with different materials, namely metal sheets without insulation, ceramic tiles without insulation, and ceramic tiles equipped with insulation. The RTTV calculation results show that the roof that best meets the energy conservation criteria is a ceramic tile roof that uses insulation, and the most energy-wasting roof is a metal sheet roof without insulation.

In the modern era, mobile applications for mountain climbers are increasingly important because they help them find accurate navigation and important information about their journey. In this research, we developed an approach to optimize the display design of a mountain climber application using GPS. We utilize GPS technology to provide accurate mapping and navigation, with a focus on an easy-to-understand and informative user experience. To ensure that the app was useful and effective, the development process on AdventHub, the app we'll be discussing, involved testing on a specific group of users. The research results show that the proposed method can enable mountain climbers to explore nature more safely and efficiently, improving performance and user satisfaction. so that mountain climbers do not experience difficulties with internet signals to access climbing routes and help them avoid.

Almost no childhood illnesses are immediately serious, most illnesses in children start with symptoms of mild illness such as fever, cough, runny nose, diarrhea and constipation or difficulty defecating. In general, people already understand quite well how to deal with symptoms of minor illnesses in children. But it would be better to include medical participation in detecting symptoms of disease, because many symptoms of disease are considered trivial by some people but can be diseases that are fatal for children. Therefore, it is necessary to create an application based on medical knowledge to diagnose diseases in children which can be used as a tool to obtain information about children's diseases and provide recommendations as the first action that must be taken to overcome diseases in children. The author created this application using the Visual Basic 06 programming language as a helper application for simulating the application created.

PEMANFAATAN APLIKASI DIGITAL MARKETING SEBAGAI STRATEGI PEMASARAN BISNIS PADA UKM SADAWIRA STORE

The utilization of digital marketing can serve as a strategic choice in product promotion, facilitating entrepreneurs in monitoring and satisfying the needs and desires of potential consumers. Conversely, from the perspective of prospective consumers, digital marketing can function as a means to ease the search for information about products. However, its adoption is not widely recognized by business operators, especially Small and Medium Enterprises (SMEs) such as Sadawira Store, which still rely on conventional marketing systems. This initiative is designed with the following objectives: 1) enhancing the knowledge and skills of Sadawira Store SME operators in marketing management to boost product sales on a larger scale and improve SME competitiveness, and 2) improving the mastery of digital marketing among SME operators to attract the interest of potential consumers through the use of Digital Marketing applications and Marketplaces. The implementation method of the Digital Marketing Camp includes: 1) observation and interviews; 2) problem identification; 3) creation of Digital Marketing applications; 4) showcase presentations; 5) preparation of the Digital Marketing Camp activity report, including training outcomes, progress reports, and a final report; and 6) creation of a national journal article. The results of the activity implementation include the achievement of all activity targets, successful collaboration with partners, broader product marketing reach, and increased competitiveness for Sadawira Store SMEs.

Infrastruktur Hijau Di Jakarta Berperan Penting Dalam Mengurangi Polusi Udara

Jakarta has poor air quality with a lot of air pollution. Jakarta has limited green open spaces, so the existing air pollution cannot be optimally addressed. This research aims to highlight the role and potential of urban green infrastructure in reducing dangerous air pollution to human health and improving air quality in Jakarta. The research method involves data collection, remote sensing observations, and data analysis utilizing various information provided by the Meteorology, Climatology, and Geophysics Agency (BMKG) and several reliable websites that provide necessary information regarding air pollution in Jakarta. Observations in Jakarta were conducted at twenty points, while observations in Bogor were conducted at two points. Data obtained from remote sensing observations at twenty locations in Jakarta indicate that air quality in Jakarta is on average at unhealthy levels. Meanwhile, data obtained from observations in Bogor show that air quality in Bogor is still healthy. The average air quality in Jakarta is 131, while the average air quality in Bogor is 31. These monitoring results are certainly worrying for the health of the people living and engaging in various activities in Jakarta. Therefore, this research aims to increase public awareness of the importance of clean air and improve green infrastructure to enhance air quality in Jakarta.

Calculating the cost of production (HPP) is an important thing to pay attention to because competition between companies is increasing in producing quality products at fairly competitive prices. This research was conducted at the holy cookies shop. The aim of this research is to determine the cost of donut production and compare the calculation of the cost of donut production implemented by the company with calculations using the full costing method and to analyze the results of calculations using the full costing method that have been carried out.

Review Biodegradasi POME dari Sudut Pandang Penggunaan Bioreaktor

Palm oil industry is one of the biggest, important and prominent global agriculture industries. The global production of palm oil was around 76.538 million metric tons in 2021. In that period, Indonesia and Malaysia were the leading exporters of palm oil worldwide (Indonesia exported 44.500 MT and Malaysia 19.700 MT). However, enermous volumes of production has subsequently discharged large volumes of a palm oil mill effluent (POME). Numerous biological and physicochemical treatment processes have been used in bench or pilot scale to treat the POME, but no one process could be used alone on a commercial scale because of the huge volume of adsorbents and coagulants necessary. As a result, the entire treatment is impractical and uneconomic. The aim of this review is to discuss various existing treatment process, type of bioreactor chosen and conversion of POME to renewable biogas such as biomethane and biohydrogen on a commercial scale.

Selection of a suitable treatment process and type of bioreactor is very important in processing POME and increasing the resulting product, both in the form of biofuel and other organic compounds.
