Abstract

Higher Education institutions play an important role in the development of Science and Technology. They are supported by adequate facilities for carrying out educational activities, research, and innovation development through Special Purpose Forest Areas (KHDTK/Kawasan Hutan Dengan Tujuan Khusus). KHDTK is a forest area designated by the government for public purposes such as research and development, education and training, and religion and culture, the management of which is given to customary law communities, educational institutions, research institutions, and social and religious institutions. The research aims to identify wind direction, wind speed, and slope. This research uses a quantitative approach with the instruments of ArcGIS and Google Earth Pro and the analysis technique of WRPlot.The research results show that the wind speed and direction in 2023, between January and March, in the Undip MIL Field Laboratory area was strong, most of which blew from the northwest. In April, the wind speed decreased, and the direction of wind gusts changed starting from the south. Stable conditions were shown between May and December, with an average wind speed of 2.7 m/s and some wind gusts coming from the southeast. Moreover, the MIL UNDIP Field Laboratory has three types of slope classes: flat, gentle, and wavy slopes, with a value of 6.6%, 13.3%, and 20%, respectively.

Abstract

In the equatorial region, Indonesia experiences distinct wet and dry seasons influenced by monsoon. The country's agricultural sector is highly susceptible to the impacts of climate change, including extreme weather events and shifting seasonal patterns due to global warming. This study aims to analyze variations in rainfall intensity and their effects on the onset of the seasons in Indonesia from 2001 to 2022. The research used GSMaP data, focusing on the area between 6° N - 11° S and 95° - 141° E. The start of the season was determined based on rainfall criteria from BMKG. The findings reveal significant changes in the onset of the rainy and dry seasons in regions such as Sumatra and Kalimantan, with the maximum change being 8 dasarian. The study also indicates that the rainy season during the 2012-2022 period is shorter compared to the 2001-2011 period, resulting in a longer dry season. Furthermore, the maximum standard deviation is 14 dasarian, allowing the season's start to shift by up to 14 dasarian annually in certain areas of Indonesia. ENSO can influence changes in the pattern of the start of the season.

Abstract

The potential of oil palm empty fruit bunches (OPEFB) as a raw material for membrane production has not been fully explored. OPEFB waste contains a relatively high cellulose content, a natural polymer that can serve as a precursor for plastic and membrane synthesis. Membranes are semi-permeable barriers commonly employed in applications such as clean water purification and liquid waste treatment. To utilize cellulose from OPEFB, it must first be converted into cellulose acetate (CA) via an acetylation reaction. Cellulose acetate is a biodegradable polymer known for its hydrophilic nature, high chemical stability, and mechanical strength, making it a widely used material in membrane technology. Moreover, CA is suitable as a matrix for developing nanocomposite membranes with enhanced performance characteristics. Membranes are typically fabricated using the phase inversion technique, involving solvents such as acetone or dimethylformamide (DMF). The resulting membrane properties—including morphology, porosity, and chemical interactions—depend on the choice of polymer and additives in the casting solution. Additives such as nano-silica and polyethylene glycol (PEG) are often incorporated to improve tensile strength, increase hydrophilicity, and control pore size distribution. Optimizing the composition ratios of cellulose acetate, solvent, and additives is essential to achieve desirable properties, particularly for ultrafiltration (UF) applications. OPEFB offers promising potential as a sustainable, renewable resource for producing UF membranes, supporting circular economy principles and waste valorization in environmental applications.

Abstract

Cardiovascular disease (CVD) represents a profound global health challenge, contributing to an estimated 17.9 million deaths annually worldwide. In Indonesia, the burden of CVD is particularly significant, with coronary heart disease prevalence at 1.5% and Non-Communicable Diseases (NCDs), including CVD, accounting for 73% of all fatalities. Community-based programs, such as Prolanis, have been implemented as key intervention strategies. This systematic review analyzes the effectiveness of these programs in reducing CVD risk factors among NCD patients in Indonesia, examining their impact within the complex environmental and socio-cultural context. The methodology involved collecting articles from Google Scholar, PubMed, and ScienceDirect, applying keywords in PICO format, and filtering using the PRISMA flow diagram, ultimately including six articles for detailed analysis. Findings indicate that community-based programs generally contribute positively to controlling cardiovascular risk factors through health education and regular monitoring. However, effectiveness varies, influenced by intervention duration, participant adherence, and individual health conditions. This variability underscores the profound influence of broader environmental factors, including air and water quality, food environment, green space access, waste management, and noise pollution, all prevalent challenges in Indonesia. Furthermore, socio-cultural factors, such as traditional health beliefs, communal habits like gotong royong, and socioeconomic disparities, significantly mediate program acceptance and adherence. This analysis highlights the imperative for holistic, context-specific, and interdisciplinary approaches to CVD prevention in Indonesia, integrating public health interventions with environmental improvements and culturally sensitive strategies to enhance overall program effectiveness and sustainability.

Abstract

Anaerobic digestion for biogas production was assessed utilizing egg-laying chicken, broiler chicken and cow dung as co-substrate. This was demonstrated in varying reactors named R1, R2, R3, and R4 containing various proportions of egg-laying chicken, broiler chicken and cow dung with a total solid concentration of 8%. This experiment was carried out for 40 days at a temperature of 25ºC. The volatile solid and chemical oxygen demand for all the reactors were as follows; 29.1, 56.6, 44.7, and 36.6% and 54.5, 89.17, 70.1, and 64.01% respectively. R2 contains 75% egg-laying chicken and 25% cow dung gave the optimal outcomes; a methane yield of 85.4%, and VS reduction of 56.6%.

Abstract

Efforts are required to save energy and utilize energy efficiently because of fossil fuel depletion. The purpose of this study is to determine the performance of the Tutong CCPP through a study of energy and exergy efficiency, also exergy losses analysis by determining four scenarios. Energy and exergy analysis using the Cycle Tempo program obtained the results of energy efficiency in scenario 1, which is 49.26%, almost the same as the energy efficiency in scenario 2, which is 49.1% where the CCPP operates with the same GT and ST loads but in scenario 2 the ST ASV experiences actuator damage. Scenario 3 obtained CCPP efficiency of 47.6% and scenario 4 obtained open cycle efficiency of 28.2%. The largest exergy loss occurred in the Condenser, which was 81.9% in scenarios 1 and 2 and 83.4% in scenario 3. From these results, it shown the greatest exergy loss occurred in scenario 3 where two ACC fans were not functioning, resulting in greater losses due to suboptimal vacuum. A significant exergy loss also occurs in the combustion chamber, which are 15.1%, 15.05%, 15.6% in scenarios 1, 2, 3 and also 16.7% in scenario 4. A large exergy loss in scenario 4 also occurs in the chimney, that is 16.7%.
