Abstract

Fires in coconut plantations, especially on tropical peatlands, cause serious environmental and economic problems. While most studies focus on oil palm, this literature review summarizes the causes, impacts, prevention methods, and restoration strategies specific to coconut plantations. The review shows that fires are mainly triggered by cheap land-clearing practices and the accumulation of dry wastes like husks and fronds, which become highly flammable during El Niño droughts and over-drainage. These fires cause direct palm mortality, reduce crop yields for up to three years, cause peat subsidence, and generate dangerous smoke haze that harms public health. To prevent these fires, strategies like proper water management, community involvement, and satellite or drone monitoring are essential. For post-fire recovery, maintaining the surviving coconut canopy and using coconut fiber as mulch offer cost-effective ways to restore soil and biodiversity. In conclusion, managing fires requires a combination of better waste management, water control, and active community participation.

Abstract

The rapid development of soft pneumatic actuators (SPAs) has driven a transition in manufacturing approaches from elastomer-based casting to additive manufacturing (AM). Although both methods have been widely adopted, systematic comparative studies to support manufacturing method selection remain limited. This study proposes a comparative evaluation framework to assess casting and additive manufacturing based on three key parameters: relative cost, fabrication time, and mechanical characteristics. The analysis was conducted through a structured literature review and semi-quantitative synthesis of 29 publications published between 2015 and 2025. The results indicate that casting provides lower material costs and superior structural homogeneity, whereas additive manufacturing offers greater design flexibility, more complex internal geometries, and higher production repeatability. The proposed evaluation framework provides a conceptual basis for selecting the most appropriate SPA manufacturing method according to application requirements, production scale, and available resources.

Abstract

Recycled high-density polyethylene (rHDPE) offers a sustainable alternative to virgin plastics, but repeated processing can degrade its mechanical properties, motivating reinforcement with natural fibers and fillers. This study investigated the combined effect of coir fiber and rice husk ash (RHA) on the mechanical and burning-rate characteristics of rHDPE composites using a two-stage experimental design. In Stage 1, coir fiber content (5, 10, and 15 vol.%) was varied to determine the optimum reinforcement level based on impact strength. In Stage 2, the selected optimum fiber content was combined with RHA (5 and 10 vol.%) to evaluate tensile strength and burning behavior, tested according to ASTM D638, ISO 179, and ASTM D635, respectively. Results showed that 10 vol.% coir fiber produced the highest impact strength (16.36 kJ/m²), while higher fiber loading reduced toughness due to agglomeration and void formation. The composite with 5 vol.% RHA exhibited superior tensile strength (10.46 ± 1.23 MPa), whereas 10 vol.% RHA improved ignition resistance, extending ignition time to 14 s. These findings demonstrate that alkali-treated coir fiber and RHA can enhance rHDPE performance, supporting the valorization of plastic and agricultural waste into sustainable composite materials.

Abstract

Evacuation route maps are essential visual safety media during emergency situations. However, compliance evaluations against the ISO 23601:2020 standard in regional general hospitals remain lacking. To evaluate the compliance level of the evacuation route map on the 1st floor of The Hospital based on ISO 23601:2020, identify the impact of visual safety gaps, and redesign the map. This study used a descriptive quantitative design to evaluate 6 map units using a checklist of 12 ISO 23601:2020 indicators and Guttman Scale data analysis. The evaluation showed that only 5 out of 12 indicators (41.67%) met the criteria (poor category), while 7 out of 12 indicators (58.33%) failed to meet them. Major gaps included the absence of "you are here" information, incomplete safety symbols, non-standard color usage, missing legends and emergency instructions, and outdated maps. A redesign was developed incorporating initial position markers, complete safety symbols, ISO standard safety color schemes, legend information, emergency instructions, mapping of 2 outdoor assembly point locations, and strategic placement recommendations. This redesign is expected to enhance safety communication effectiveness and serve as a reference for improving emergency response preparedness in other regional general hospitals.
