Abstract

This study aims to examine how technology, particularly social media, plays a role in increasing community participation in the development of the sago forest tourism area in Kampung Sereh, Sentani District, Jayapura Regency. The area holds strong natural and cultural potential, yet its development as a tourist destination remains underutilized. The research adopts a qualitative descriptive approach using interviews, field observations, and document analysis. findings reveal that digital technology-especially social media platform such as Instagram and Facebook-has broadened the reach of tourism promotion. Young people in the community have started to use these platforms to share tourism- related activities and local cultural practices. However, challenges persist, including low digital literacy, limited access to proper devices, and the lack of technical training and assistance. Community participation is evident in various aspects, such as organizing cultural performances, preparing traditional food, and engaging in environmental conservation. This study recommends ongoing digital training and the formation of a community- managed promotional team to support sustainable and inclusive tourism development.

Abstract

Wahno Subdistrict in Abepura District, Jayapura City, faces drainage problems that disrupt the area’s water management function. The varied topography, population growth, and the community’s habit of disposing waste into drainage channels have reduced the system’s capacity and caused frequent waterlogging during rainfall. This study aims to analyze the existing condition of the drainage channels in Wahno and to evaluate their effectiveness in conveying stormwater flow. The research methods include field surveys, channel dimension measurements, capacity calculations, and analysis of the effective volume compared to actual conditions affected by waste and sedimentation. The data were analyzed using quantitative and descriptive approaches to assess the performance level of the drainage system. The results show that most drainage channels in Wahno are not functioning optimally, with an average effectiveness of only 45–60% due to blockages caused by waste and sedimentation. The main factors reducing drainage effectiveness are decreased storage capacity, substandard design, and lack of regular maintenance. It is concluded that improvements to channel capacity, better waste management, and routine maintenance programs are necessary to enhance the drainage system’s effectiveness.

Abstract

Green Open Space (GOS) is an essential element in urban spatial planning that functions to maintain air quality and ecosystem balance. This research aims to analyze the influence of GOS on the concentration levels of Carbon Dioxide (CO2​) in the urban area of Jayapura City. The study locations were focused on two areas with distinct characteristics: Jalan Sam Ratulangi, which has high vegetation coverage, and Jalan Percetakan, which is dominated by built-up areas and dense commercial activity. The methods used include spatial analysis utilizing Landsat 8 satellite imagery Band 4 (Red) and Band 5 (NIR) to calculate the NDVI (Normalized Difference Vegetation Index), a vegetation time series analysis from 2019–2024, and direct CO2​ concentration measurements taken at three different times (morning, noon, afternoon). The data was processed using ArcGIS with the Kriging Interpolation method to generate spatial distribution maps of CO2​ in both locations. The results show that Jalan Sam Ratulangi has a GOS area of 6.13 ha (94%), while Jalan Percetakan has only 2.95 ha (31%). This difference significantly impacts CO2​ levels, with an average concentration of 484 ppm at Sam Ratulangi, which is lower than Percetakan's average of 567 ppm. The highest CO2​​ value at Percetakan reached 649 ppm during the afternoon, whereas Sam Ratulangi recorded only 488 ppm. This study proves that the wider and healthier the GOS, the lower the CO2​​ concentration detected. These results demonstrate that vegetation plays a significant role in reducing carbon emissions in urban areas, supporting the crucial role of GOS in maintaining air quality and supporting sustainable urban development in Jayapura City.

Abstract

Denny's house is one of the houses that uses a minimalist architectural concept. The minimalist concept has become a trend in the world of architecture, because of its simple yet effective concept, minimalist design has become one of the most preferred styles by graphic design professionals, architects, and artists (Aliwafa, 2023). The actualization of the Vitruvius architectural concept is based on Vitruvius's theory of Utility (Function Aspect), Firmitas (Strongness and Structure Aspect), and Venustas (Beauty). By comparing Vitruvius's theory with Henry Wotton's Theory, the aim is to actualize the architectural concept in the contemporary design of Denny's house as well as become a case study that can be accepted by the reader's audience. This case study uses descriptive qualitative techniques of data processing that aim to achieve study results on a comprehensive phenomenon. The application of the Vitruvius architectural concept is the focus of discussion in the contemporary design of the facade of Denny's house which becomes a reference for the discussion to examine with an architectural approach. The house becomes the initial locus of discussion by prioritizing the function of beauty, the function of strength or structure, and the function of venustas or beauty. Vitruvius is a theory used to examine the application of design theory by providing a precedent study of Denny's architectural work, which uses a minimalist functionalist theme. This study examines Vitruvius' theory regarding the relevance of design to Denny's home.

Abstract

This study aims to analyze work time efficiency and determine standard time in the furniture production process at CV. JM Putra using the Time and Motion Study method. The background of this study stems from the problem of low production time efficiency due to suboptimal work methods, ineffective work area layout, and a lack of systematic work time measurement. The research was conducted quantitatively and descriptively through direct observation, interviews, and time measurements using a stopwatch for the table production process, which consisted of five main activities. The results showed that the average total cycle time for one table unit was 347.25 minutes, with the activity of assembling the table frame being the longest activity at 120.13 minutes or about 34.6% of the total working time. After performance assessment and the addition of a 15.5% allowance factor, the standard time was obtained at 129.03 minutes. These results indicate that the activity of assembling the table frame is the most critical point that affects production efficiency. The implications of this study show the importance of improving work methods, area layout, and operator training to increase labor productivity. The application of standard time measurement results can be used as a basis for setting work standards, production capacity planning, and a more objective labor incentive system.

Abstract

The limited urban land in Greater Jakarta demands the emergence of a residential approach that is more adaptive to the growing needs of space. This study examines the application of the concept of a growing house in the residence of Rumah Swatantra by Studio Dasar. The research method uses a qualitative-descriptive approach through literature studies and direct interviews with the designer architects. The results of the study show that the application of modular patterns and concrete hollow infill structure systems provides the flexibility of space growth without the need to dismantle the basic structure. The process of space growth occurred gradually following the development of the family from 2017 to 2024, and showed that the quality of space can still be maintained even though the building is built in stages. These findings confirm that the concept of growing houses can be an alternative strategy for sustainable housing in urban areas that experience limited land. In addition, this study highlights the importance of careful spatial planning from the early stages of development so that spatial expansion can be carried out efficiently, measurably, and in harmony with the needs of residents. This approach not only improves the comfort and functionality of the space, but also minimizes construction waste and future renovation costs.

Abstract

In the development of a construction project, cost control is very important in the process of managing project costs. Many problems will be encountered in a construction project such as wasteful use of materials, unskilled labor and late completion of the project. This causes waste of costs that do not match the specified budget. In the construction project of the Rectorate of the Sorong City Health Polytechnic building, a budget of Rp. 36,570,996,788.55 is required. This study aims to make savings on previously planned costs, in addition to knowing the comparison of total project costs after analysis. The method used in this study is the Value Engineering method. The Value Engineering method is a method used to identify and eliminate unnecessary activities or reduce costs without reducing function. There are 4 stages of the work plan in this method, namely: Information Stage, Creative Stage, Analysis Stage, and Recommendation Stage. After conducting the Value Engineering analysis, savings of Rp. 654,875,786.25 or 1.79% of the total project cost were obtained. The analysis was conducted on the two highest-cost work items: wall and floor work. For the wall work, it was recommended that the HPL wall covering be replaced with plasterboard, while for the floor work, it was recommended that the 60x60 granite be replaced with 60x60 ceramic tiles.

Abstract

A decline in performance in automatic motorcycles that have been used for a long time is a common problem caused by wear and tear on the Continuously Variable Transmission (CVT) system. This condition results in a reduction in the clamping force of the V-belt on the pulley, causing slippage and a decrease in transmission capacity. Based on the manufacturer's specifications, the torque is 8.32 Nm at 5500 rpm, while the test results show a torque of 7.41 Nm at 6500 rpm, a decrease of 10.9%. The study aims to analyze the effect of variations in pulley angle and surface roughness on the torque value of a 108 cm³ automatic motorcycle as a method to restore transmission performance without replacing the main components. The pulley angles tested were 14°, 13.8°, and 13.5°, while the surface roughness was varied based on the turning process with cutting inserts having nose radii of 0.2 mm, 0.4 mm, and 0.8 mm. The testing was conducted using a dynamometer at an engine speed range of 6000 – 9000 rpm. The results showed that the combination of a 13.8° pulley angle with a 0.2 mm cutting insert nose radius produced a torque of 7.41 Nm at 6500 rpm, an increase of 8.2% compared to the standard 14.5° configuration, which only produced 6.85 Nm. Modifying the pulley angle and surface roughness was proven to increase the V-belt clamping force, thereby improving transmission performance.

Abstract

Many used ABS plastic wastes have problems in their management. The aim of this research is to obtain a prediction of the fatigue life of a mixture of ABS plastic and used ABS as an injection molding product. The research method is carried out through the stages of mixing used ABS with a volume of 10%, 20%, and 30% in ABS grade A and grade B; making fatigue test specimen molds according to R. R. Moore standards, injection molding of a mixture of used ABS and ABS grade A and grade B, checking the straightness and smoothness of the specimen surface, fatigue testing with increasing serial loads, analysis and making a graph of bending stress (S) against fatigue life (N) (S-N Curve). The results of the study showed that the addition of used ABS had an effect on the fatigue life of both grade A and grade B of ABS, where the fatigue life of grade A of ABS increased with the addition of the volume percentage from 0% -30% of used ABS with the highest value at the addition of 30%, namely 43698.9 cycles, while in grade B of ABS, the fatigue life decreased with the increase in volume from 0% -30% with the highest fatigue life in grade B of ABS plastic without a mixture or 0%, namely 41377.5 cycles, the implication of which is that the addition of 0% -30% of used ABS in grade A can increase the fatigue life, but grade B of ABS actually decreases its fatigue life.

Abstract

This study aims to analyze production performance and the factors influencing the productivity of mining operations at PT. XYZ during August 2025. The evaluation covers production achievement against the corporate work plan (RKAP) and the owner’s operational plan, equipment availability (Physical Availability), the productivity of loading and hauling units, and various types of loss time that reduce effective working hours. The results indicate that production realization reached only 65% of the RKAP target, while achieving 102% of the owner’s plan for total material. Low equipment availability, high loss time such as no hauler, wait operator, and front preparation, as well as the underperformance of 80-ton and 100-ton units, were identified as the main contributors to production deviation. Additional influencing factors include unit reassignment, suboptimal haul road conditions, and insufficient operational fleet numbers. The study recommends optimizing fleet management, enhancing preventive and predictive maintenance programs, reorganizing hauling workflows, and controlling dominant loss time sources to improve operational efficiency and production target achievement in future periods.
