Abstract

The availability of clean water is a serious challenge amidst rapid urbanization, environmental pollution, and climate change, especially in Bali. This condition is exacerbated by limited access to PDAM (Regional Water Company) and the declining quality of ground and surface water. This research developed TOPO (Traditional Purifier Pot), a household water filter device based on traditional pottery from Sentra Binoh, North Denpasar. TOPO is designed as a solution for providing clean water that is affordable, environmentally friendly, while also elevating local Balinese values ​​through functional and aesthetic design. The research method combines qualitative and quantitative approaches, including literature studies, observations, interviews, and laboratory tests on well water quality before and after filtration using a pottery filter made of clay and paras powder. Test parameters include physical, chemical, and microbiological aspects referring to Minister of Health Regulations No. 2 of 2023 and No. 66 of 2014. The results show that the pottery filter is able to reduce contaminant levels significantly, although some elements such as manganese still exceed the safe threshold. Therefore, TOPO is more appropriate for use as a container for raw water that is boiled before consumption. The TOPO design was developed through an ATUMICS approach, using the metaphor of the turtle as a symbol of balance, sustainability, and the water element in Balinese culture.

Abstract

In the urban transportation system, Semarang is one of the cities with a high level of vehicle density, causing traffic congestion. This is also compounded by side obstacles, such as vehicles entering and exiting, stopped vehicles, parking on the roadside, pedestrians, and pedestrians. The Majapahit Road section is one of the intercity connecting roads. Thus, this road plays a very important role in serving a fairly large traffic flow. So that on this Majapahit Road section often experiences congestion that occurs not only at certain hours, because on this road section congestion is also caused by the presence of shopping centers, education, and shops. The important role of Majapahit Road results in vehicle queues and traffic delays, vehicle buildup, travel time delays (delays), and a decrease in the level of road service. Analysis of the performance of urban road sections, with performance indicators namely traffic flow (Q), capacity (C), degree of saturation (DS), free flow speed which is carried out with various performance indicators namely free flow speed (FV), as well as analyzing the level of service (Level of Service / LOS) on the road section. Based on calculations and analysis of this road segment in August 2025, the traffic flow (Q) value was 3,863.55 pcu/hour, the capacity value (C) was 2,821, and the degree of saturation (DS) was 1.37, exceeding 1. These values do not meet the required conditions. The free flow speed (FV) was 37.26 km/hour, and the level of service (LOS) was categorized as level F. Based on the calculation results in 2025, solutions/alternatives are needed to reduce the degree of saturation (DS) value by increasing the capacity value.

Abstract

Road traffic injuries are a serious global health issue, especially in nations with low and moderate incomes. In 2021, for example, the Asia-Pacific region accounted for approximately 60% of all worldwide traffic fatalities, a figure that highlights the urgency of the problem. In Indonesia, a developing country, motorcycles are the most popular mode of transport, but they are also the deadliest, with riders accounting for over 70% of traffic deaths between 2013 and 2018. This issue is particularly pronounced among young adults (aged 18–25), who are responsible for 51% of all traffic accidents in the country.To address this, a comprehensive study was conducted using a modified Motorcycle Rider Behaviour Questionnaire (MRBQ) engaged to the Indonesian context. The research aimed to identify factors associated with unsafe riding behaviors, which are primarily driven by human factors. Of the 96 riders approached, 92 participated (96% response rate); most were male (61.25%), aged 19–20 years, students (97.80%), and used automatic motorcycles (89.70%), with 72% having less than 10 years of riding experience and 58% reporting a near-crash in the past year. Traffic violations (M = 3.65 ± 0.46) and errors (M = 2.12 ± 0.32) were the most prevalent behaviors and were significantly associated with negative attitudes, social norms, and crash involvement (r = 0.15–0.45, p < 0.01), whereas stunt-related behaviors were rare (M ≈ 1.02) and formed a distinct factor.These findings highlight the need for targeted interventions that focus on psychological factors like negative attitudes and social norms, which were found to be strongly linked to risky riding and crash history. This study demonstrates that the MRBQ exhibits a context-specific four-factor structure (errors, violations, safety gear violations, and stunts) among Indonesian young adult motorcyclists with strong psychometric support, while also highlighting the need for further item refinement and alternative data collection methods to address contextual behaviors.

Abstract

Competence in concrete quality testing is an essential skill for vocational high school graduates in the construction sector to meet the demands of the construction industry. However, limited laboratory facilities and practical experience often hinder students from mastering non-destructive testing methods, particularly the Rebound Hammer Test. This community service program aimed to improve the knowledge and practical skills of students from the Building Construction and Housing Engineering Program at SMK Negeri Pringsurat in conducting concrete quality assessment using the Rebound Hammer Test. The program was implemented through a sequence of activities, including needs assessment, classroom instruction, equipment demonstration, guided hands-on practice, and evaluation using pre-tests, post-tests, practical observations, and participant response questionnaires. The results demonstrated a significant improvement in students' understanding of concrete quality testing principles, testing procedures, and interpretation of test results, as reflected in higher post-training evaluation scores. Furthermore, participants were able to operate the testing equipment according to standard procedures and expressed highly positive responses toward the practice-based learning approach. The program also strengthened teachers' instructional capacity through the provision of a training module that can be integrated into future laboratory learning activities. Although the program was limited by training duration and the availability of testing equipment, the integrated approach combining theoretical instruction, demonstrations, and guided practice proved effective in enhancing participants' competencies. This training model has the potential to be replicated in other vocational schools to support the development of industry-oriented competencies in the construction sector.

Abstract

The utilization of wood waste as an additive in mortar has attracted increasing attention as an environmentally friendly approach to reducing industrial waste while promoting sustainable construction materials. This study aimed to evaluate the effect of wood waste addition on the physical and mechanical properties of mortar, particularly its early-age compressive strength. Wood waste was incorporated into the mortar mixture at proportions of 0% (control), 10%, and 15% by weight of fine aggregate. The tests included measurements of mass, density, and compressive strength of cube mortar specimens at the age of 3 days. The 3-day testing period was selected to evaluate the early-age characteristics of the mortar as an indicator of its initial physical and mechanical performance. The results revealed that increasing the wood waste content reduced the mass, density, and compressive strength of the mortar. The control mortar achieved an average compressive strength of 1.07 N/mm², whereas the incorporation of 10% and 15% wood waste resulted in strength reductions of approximately 31% and 66%, respectively. This reduction was mainly attributed to the low density, porous structure, and hygroscopic nature of wood waste, which increased mortar porosity, reduced the effective water available for cement hydration, and weakened the interfacial transition zone between the cement paste and wood particles. At higher wood waste contents, several specimens experienced premature failure during the compression test, indicating reduced structural integrity. Despite the reduction in compressive strength, the incorporation of wood waste decreased the density of the mortar, indicating its potential for producing lightweight mortar. Therefore, wood-waste mortar is more suitable for non-structural applications, such as masonry and plastering, while simultaneously supporting sustainable construction through the beneficial utilization of industrial wood waste
