Abstract

Adolescence is an important transition phase from childhood to adulthood which is marked by physical, emotional and social changes. At this stage, teenagers are in the process of searching for their identity so they are very vulnerable to the influence of the environment, peers and social media. Lack of self-control, minimal understanding of the risks of dangerous behavior such as promiscuity, smoking and drug abuse, as well as weak parental attention and moral education further increase teenagers' vulnerability to risky behavior. Indonesian adolescent mental health data for 2024 shows that one in three adolescents, or around 15.5 million individuals, experienced mental health problems in the last 12 months, with anxiety disorders being the most common cases (28.2% of girls and 25.4% of boys). In addition, around 2.45 million teenagers experience at least one mental disorder. Factors such as academic pressure, family relationship dynamics, bullying, gadget addiction, and socio-economic conditions also influence their mental health conditions. This research on adolescent mental health aims to provide education and prevention efforts against risky behavior that can damage physical and mental health. Through this educational activity, it is hoped that teenagers will have a better understanding of the consequences of their actions, be able to maintain mental health, and build strong character to face future challenges positively.

Abstract

Occupational Health and Safety (OHS) is an approach designed to prevent workplace accidents that may cause death, injury, or disability. If potential hazards in the workplace are not adequately identified and managed, they can lead to fatigue, musculoskeletal disorders, injuries, or serious accidents. Due to the high-risk nature of its production processes and the lack of ergonomic considerations, the kerupuk processing industry at UD Mamak Kito must pay greater attention to Health, Safety, and Environment (HSE). One method to support OHS implementation is the HAZOP (Hazard and Operability Study) method, which systematically identifies potential hazards in the workplace. The study identified ten high-risk conditions, primarily associated with the use of personal protective equipment (PPE), ergonomics, and exposure to high heat or hot oil. Six moderate-risk conditions were also found, including failure to use PPE and minor environmental hazards. Low-risk factors, including minor cuts and slippery surfaces, were additionally observed. Based on these findings, recommended improvements include enhancing workplace conditions and promoting safer work practices to reduce the risk of accidents and occupational health problems.

Abstract

Roads are land transportation infrastructure that includes all parts of the road system, such as connecting structures, complementary buildings, and equipment intended for traffic activities on, above, and below the ground surface, including water surfaces, excluding railways, haul roads, and cable roads. This research aims to identify the condition of environmental roads in Lereng Village, Kuok District, and to produce a spatial distribution map of the environmental road network. The study applies a survey-based quantitative descriptive method, focusing on describing actual conditions and revealing factual problems found in the field. Primary data were obtained through direct field observations and measurements, while secondary data were collected from related institutions. Geographic Information Systems were selected as the main analytical tool due to their ability to manage spatially referenced data, process complex structures, and efficiently support decision making related to road infrastructure management. The results show that most environmental roads in Lereng Village are in damaged condition, dominated by potholes, longitudinal cracks, and surface deterioration. Several roads are classified as heavily damaged, including Transad Alley 1, Transad Road 2, and other local roads within the village area. These conditions reduce driving comfort and safety for road users and indicate the urgent need for improvement. The mapping results produce an environmental road condition map with priority scores ranging from 9 to 18. Roads with priority values greater than 7 are categorized as requiring routine maintenance, providing a basis for planning maintenance and rehabilitation programs.

Abstract

Research-based elective courses can be an alternative to Student-Centered Learning (SCL) classes. Project-based learning (PjBL) can be an attractive learning method. PjBL was developed through lecturers' research interests to balance the tri dharma of higher education. This study aims to give an example of creating an elective course in an SCL class. Kansei Engineering in Affective Design (KEiAD) class is a PjBL elective course successfully implemented in the Industrial Engineering Department of Universitas Trisakti by appointing the lecturer's research. Course learning outcome (CLO) was developed through five major stages of the KEiAD framework: identifying Kansei users, selecting design concepts, identifying key design elements, formulating design, and prototyping. The first lecture had good results. Eleven groups containing two to three students could formulate 11 affective products. All students also succeeded in achieving the expected outcomes of this course. Several students showed interest in using KEiAD as a final project topic. In the future, a quota for elective courses that is too large, such as 32 students, is considered too large because the assistance in class is not intensive enough. Smaller student quotas and R studio alternatives can be considered for continuous improvement.

Abstract

Riau Province is one of Indonesia’s largest palm oil–producing regions, generating substantial biomass waste such as palm kernel shells. One potential use of this waste is Palm Kernel Shell Ash (PKS-Ash), which contains silica (SiO₂) and alumina (Al₂O₃) that are beneficial for cementitious reactions. This study aims to evaluate the effect of PKS-Ash as a cement additive on the properties of Cellular Lightweight Concrete (CLC) bricks, particularly unit weight, water absorption, and compressive strength. A laboratory-scale experimental method was applied. The test specimens were produced using cement, sand, water, a foaming agent, and PKS-Ash with variations of 0%, 4%, 6%, and 8% by weight of cement. All specimens were tested at curing ages of 7, 14, 21, and 28 days in accordance with SNI 8640-2018. The results at 28 days showed that the addition of PKS-Ash significantly influenced the characteristics of the CLC bricks. Compressive strength increased with higher PKS-Ash content, reaching a maximum value of 1.775 MPa at the 8% variation, compared to 0.975 MPa for the control mixture. The unit weight of the specimens ranged from 1,304.29 kg/m³ to 1,716.44 kg/m³. Water absorption values varied, with the lowest absorption observed in the 0% mixture and the highest in the 4% mixture. The study concludes that PKS-Ash has strong potential as a sustainable additive to improve the compressive strength of CLC lightweight bricks while promoting effective utilization of palm oil industry waste.

Abstract

The development of urban areas demands the existence of community sports facilities that not only function as physical activity spaces, but also as a medium for shaping environmental quality and the identity of sustainable public spaces. The Boxing Community Center is characterized by high-intensity activities that produce special demands on thermal comfort, air quality, and spatial flexibility. This study aims to examine how an eco-futuristic appropriate is applied in the formation of the Boxing Community Center building mass composition and its implications for environmental performance and architectural expression. The research method used is qualitative-descriptive through literature review, analysis of sports building precedents, and exploration of design concepts. The results of the study show of that the application of fragmented, layered, and climate-adaptive mass composition can improve natural ventilation, daylighting, and the quality of the transition space between the building and the outside environment. In addition to contributing to energy efficiency, this mass composition strategy also creates a dynamic and futuristic architectural image that is in harmony with the character of boxing. This study confirms that the processing of building mass with an eco-futuristic approach plays an important role as a passive strategy as a basis for designing community sports facilities that have optimal environmental performance and long-term flexibility.

Abstract

Recharge areas play a crucial role in maintaining hydrological balance and sustaining groundwater resources. Uncontrolled land use change can reduce infiltration capacity and increase environmental risks such as flooding and groundwater depletion. This study aims to analyze and map the potential of groundwater recharge areas using a Geographic Information System (GIS) to support spatial planning and water resource management. The research employed secondary data consisting of rainfall, slope, soil type, and land use. Each parameter was standardized, weighted, and scored according to its influence on infiltration capacity, then integrated using a weighted overlay method within GIS software to produce a comprehensive recharge potential map. The results classify the study area into low, moderate, and high groundwater recharge potential zones. Areas with high recharge potential are predominantly associated with gentle slopes, coarse-textured soils, relatively high rainfall, and land use dominated by vegetation cover, whereas low potential zones are characterized by steeper slopes, fine-textured soils, and built-up land use. The resulting map provides a spatial representation of recharge capacity that can be used to identify priority areas for conservation and guide land use control. This study demonstrates that GIS-based multi-criteria analysis is effective for evaluating groundwater recharge potential and generating practical spatial information. The findings are expected to support decision making in spatial planning, groundwater conservation strategies, and sustainable environmental management, as well as to serve as a reference for future studies related to hydrological assessment and land use planning. It also enhances data integration, transparency, and consistency across planning processes locally.
