Liliana, Abertun Sagit Sahay, Supiyan — Wed, 12 Feb 2025 00:00:00 +0000

This study evaluates the physical properties, bulk density, water absorption, and specific gravity of artificial coarse aggregate derived from Tangkiling clay, Palangka Raya City, as well as the effect of wire fiber addition on the mechanical properties of fiber concrete. The artificial coarse aggregate was produced by firing clay at a temperature of 1000°C, resulting in rounded aggregate shapes. The bulk density of the aggregate in a loose condition was recorded at 889 kg/m³, while the water absorption was 13.69%. The specific gravity in dry and saturated surface-dry conditions was 1.260 and 1.385, respectively. The fiber concrete made with a combination of artificial coarse aggregate and wire fiber showed a hardened concrete bulk density ranging from 1890 – 2070 kg/m³. The optimal wire fiber concentration of 1.93% produced a maximum compressive strength of 20.399 MPa. However, statistical analysis revealed that the addition of wire fiber had no significant effect on increasing the compressive strength.

Wiyogo Wiyogo, Asi Pebrina Cicilia Runting, Kristanto Suryadhi, Khusnul Khotimah — Mon, 12 Feb 2024 00:00:00 +0000

This study aims to analyze the impact of education levels on environmental behavior among communities in the Katingan Watershed (DAS Katingan). The findings reveal that education levels play an important role in shaping environmental behavior, although their contribution is relatively small compared to other factors. Respondent data analysis indicates that the majority of the population has a secondary education level (high school), with occupational distribution dominated by the agricultural sector (27%), while most residential locations are situated along riverbanks (75.2%). Higher levels of education have the potential to increase environmental awareness; however, the low coefficient of determination (R² = 3.6%) suggests that education accounts for only a small portion of the variation in environmental behavior. Other factors, such as attitudes, access to environmental management facilities, government policies, and socio-economic conditions, exert a greater influence. This study concludes that a holistic, community-based approach, enhanced infrastructure access, and supportive policies are essential to fostering better environmental behavior. These findings provide a foundation for developing environmental education programs that are relevant to local needs, particularly in the agricultural sector and natural resource management.

PASSIVE LIGHTING DISTRIBUTION SYSTEM IN EDUCATIONAL BUILDINGS CASE STUDY OF PPIG BUILDING, PALANGKARAYA UNIVERSITY

Wed, 12 Feb 2025 00:00:00 +0000

This study explores the passive lighting distribution system in educational buildings at PPIG Palangka Raya University. The main focus of the study is how the distribution of natural lighting decreases significantly in spaces that are far from the lighting source, especially in buildings that have light sources on the side that is difficult to reach the entire space. Using an analysis test with the Andrewmarsh application, the distribution of lighting in the Daylight Factor was found with an average of 43.48%. The results of the study show that the placement of space towards the position of windows or openings that are less strategic causes a gap in light distribution, thus affecting visual comfort in the room. This study is expected to be a reference in designing educational buildings that are more energy efficient and comfortable for their users.

DEVELOPMENT OF A DATA LOGGER-BASED WATER LEVEL MONITORING SYSTEM FOR PEATLANDS

Wed, 12 Feb 2025 00:00:00 +0000

This study investigates the dynamics of water level (TMA), electrical current, power, and battery voltage in a data loggerbased monitoring system designed for peatlands. Data collected from October 30 to December 4, 2024, highlight significant fluctuations influenced by environmental factors, load surges, and voltage disruptions. Scenario simulations, including changes in rainfall, sudden load increases, and voltage system disturbances, were performed to evaluate the system's operational efficiency and stability. The findings indicate that TMA is highly influenced by hydrological conditions, where a 50% reduction in rainfall significantly decreases TMA, impacting the stability of current and power. A 50% load surge drives the current and power close to the system's maximum capacity, while voltage disruptions lead to a 20% increase in current and a 20% reduction in power, revealing system imbalances. Energy efficiency remains stable under normal conditions (0.0022) but drops significantly during disruptions. The study underscores the need for integrating protective technologies, such as Automatic Voltage Regulators (AVR), Overcurrent Protection, and balanced load management, to mitigate risks and maintain system stability. Additionally, improved water management in peatlands contributes to stabilizing TMA and reducing environmental impacts on electrical parameters. This research highlights the importance of a holistic approach, combining technology, hydrological management, and data-driven simulations, for sustainable operations. The findings offer practical recommendations for system enhancement, risk mitigation, and the development of future energy monitoring tools. Opportunities for renewable energy integration are also explored to ensure long-term operational efficiency and environmental sustainability.

Suwung Final Disposal Site (TPA) is a waste disposal site located in Suwung Kauh village, Denpasar District, south of the city of Denpasar, Bali. One of the problems arising from the accumulation of waste in the TPA is the presence of pollutants in the form of leachate. The aim of this research is to determine the level of concentration in the leachate and its effect on the quality of shallow groundwater around the Suwung landfill. Parameters tested on leachate include pH, chloride, turbidity, odor and color concentrations which will be compared with leachate water quality standards in the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number P.59/Menlhk/Setjen/Kum.1/7/2016 and shallow groundwater quality testing with the Regulation of the Minister of Health of the Republic of Indonesia 416/Menkes/PER/IX/1990.In the leachate water quality test, the results showed pH (7), chloride (3.0 mg/L), turbidity (194 FNU), odor and brownish black color (qualitative test using the five senses). Shallow groundwater quality tests are carried out in each well that has been determined. Testing the quality of shallow groundwater obtained results for the Suwung TPA monitoring well, pH (7), chloride (0.3mg/L), turbidity (1, 19FNU), odorless and colorless. Testing for residents' dug wells approximately 1 (one) kilometer away resulted in pH (6), chloride (1.5 mg/L), turbidity (1.95 FNU), odorless and colorless. Results from shallow groundwater characteristics testing shows that there are five parameters that meet water quality standards, namely pH, chloride, turbidity, odor and color.So it can be concluded that leachate water does not affectthe quality of shallow groundwater in residents dug wells around Suwung TPA with concentrations of pH,chloride,turbidity,odor and color

Slums always can be found in big cities in Indonesia, as a result of the impact of urbanization. This slum settlement is identical to the conditions of inadequate environmental infrastructure including the condition of houses that are almost uninhabitable. Physically, most of the house buildings use used materials. Materials such as wood / used beams for house frame structures, used boards mixed with used zinc and rust for walls, and used zinc (metal or plastic) and straw for roof coverings. The cumulative impact of the existence of these slums is a decrease in the visual quality of the urban built environment and a decrease in the quality of the health of the urban built environment. as a solution, it was stated that the model of the Simple Healthy Sustainable House of Local Bamboo Construction in this case bamboo that grows in Central Kalimantan.At present most of the design of cheap bamboo-based houses is using Petung Bamboo (Dendrocalamus Asper), while on the island of Kalimantan this type of bamboo has very little population. For this reason, it has been researched and modeled for sustainable healthy simple houses using local bamboo species whose populations are widely available in Central Kalimantan such as Suluk Bamboo (Gigantochloa Levis (Blanco)), Tamiang Bamboo (Schizotachyum Blumei Nees) and Yellow Bamboo (Bambusa Vulgaris Schard). The three types of bamboo are determined as a component of the Sustainable Healthy Simple Houses Construction, namely as Main Column component, Supporting Columns, Frame and Wall Coverings, and also as Ring Balk.
