3D printing has rapidly evolved due to its significant advantages in rapid prototyping. 3D-printed products for industrial applications require stable mechanical properties, which are influenced by various factors. The lack of a comprehensive discussion addressing the factors affecting mechanical properties is the main reason for this review. This article aims to provide an overview of Fused Deposition Modeling (FDM) 3D printing concerning the factors that influence the mechanical performance of FDM 3D products using polylactic acid (PLA) material. The article covers the impact of material factors, process parameters (such as layer thickness, infill patterns, print orientation, infill patterns, infill density, infill width, temperature, and printing speed), as well as post-processing treatments as key considerations. The contribution of this article is to explain to researchers and industry practitioners the factors that affect the mechanical performance of FDM 3D printed products.

Primary health service transformation implementation focuses on a lifecycle approach with promotive and preventive efforts and brings health services closer to cadres through Posyandu. Good integration of Primary Services requires efforts to improve the skills of posyandu cadres through E-Leaflet media. This study aims to determine the influence of e-leaflet media on improving toddler posyandu cadres' skills. This study used a quasi-experimental design with a one-size-fits-all posttest without a control group. The sample amounted to 43 posyandu cadres. The sampling technique is simple random sampling—data analysis with the Wilcoxon test. The p-value on the respondents' skills before and after being given the e-leaflet media was (p=0.001). There was a significant increase in skills after being given the e-leaflet media to the cadres of the Posyandu for toddlers. This statistically significant outcome confirms the efficacy of digital learning resources in strengthening frontline community health worker capabilities.

Coal mining has positive impacts in the form of increasing the national economy and people's income. However, it also has negative impacts, including the decrease of environmental quality such as air, soil, and noise, as well as the potential for spontaneous combustion. The research was conducted to assess the technical and economic aspects of environmental management at coal stockpiles in the Tarahan Port Unit of PT Bukit Asam Tbk to support environmental sustainability. The technical assessment of stockpile environmental management was carried out by comparing observation results with the Environmental Management and Monitoring Plan Document (RKL/RPL) and Indonesia’s applicable Environmental Quality Standards. The economic assessment focused on the cost of environmental monitoring and management by observing the discrepancies between the planned and realization in the first and second quarters. The technical assessment results show that environmental management at the stockpile has been implemented effectively. Air quality parameters and noise levels remain below the established standards, soil quality is classified good as indicated by vegetation growth, and no spontaneous combustion occurred during the observation period. The economic assessment revealed a discrepancy of 2.02% between the planned cost of IDR 121,183,548 to the actual realization of IDR 123,641,668. This increase was attributed to the construction of a dust reduction system and an operational chimney for the 2X8 MW Steam Power Plant, through the use of Electrostatic Precipitators. The study recommends a detailed inventory of environmental cost plans and potential cost escalation to anticipate risk factors. It also highlights the need for regular maintenance of machines that are known to frequently produce emissions. These efforts are expected to reduce the emissions and lower the costs of environmental management and monitoring.

Self-talk is one strategy that can increase self-awareness. This research aims to design a self-talk multimedia product that meets feasibility criteria and effectively increases students' self-awareness. Using the Borg and Gall development model, data were obtained through expert assessments, user ratings, and self-awareness scales, which were validated using Aiken's V and tested for reliability using Cronbach's Alpha. Qualitative analysis was carried out on validator and user suggestions, while quantitative analysis used feasibility percentages and t-tests. The results of the study show that multimedia self-talk is suitable for use, with 80% of media experts and 97.1% of material experts. Paired t-tests revealed significant improvements in self-awareness (p < 0.05; pretest = 72.49; posttest = 76). These findings prove that multimedia self-talk is effective in increasing students' self-awareness. The implication is that this product can be an innovation in technology-based guidance and counseling services that support students' learning independence and self-reflection.
