ANALYSIS OF WASTE BANK MANAGEMENT MODEL AROUND LAKE TONDANO TOURISM OBJECT IN SUPPORTING SUSTAINABLE TOURISM DEVELOPMENT

Unmanaged waste can cause various problems of environmental damage including threatening tourism development. The current waste problem is quite worrying because it can have a direct impact on humans, such as the entry of plastic elements into the human body through fish or food exposed to microplastics. Aim: The waste bank around Lake Tondano tourism object was studied qualitatively with the aim of describing the waste bank management mechanism to be used as a model for developing a waste bank to support sustainable tourism development. Methodogy and Results: The research data was obtained through field research through observations and interviews with waste banks around the Tondano lake tourist attraction, in this case the Mapalus waste bank located in Papakelan Village. Conclusion, significance, and impact study: The results show that the current form of waste bank management on the shores of Lake Tondano is a waste bank that is purely managed by the community. The form of management is to collect waste from the community by first going through a sorting process. After sorting, organic waste is used as fertilizer and inorganic waste is made into valuable products and can be used as souvenirs for tourists.  The waste bank program can reduce the increase in waste directly from the source. In addition, the waste bank can produce new products and provide benefits to the community. The waste bank is also a solution in the context of developing tourism on the coast of Lake Tondano

Chronic Energy Deficiency Associated with Body Mass Index of Adolescent Girls

Chronic Energy Deficiency (CED) is a nutritional issue that poses a threat to adolescents in Indonesia, particularly to adolescent girls. According to the 2018 Basic Health Survey (Riskesdas), the proportion of CED among adolescent girls in Indonesia was 36.3%. This study aimed to identify the factors associated with CED among adolescent girls in the catchment area of Poka-Rumah Tiga, Ambon City. The study was conducted in August 2022 and used a cross-sectional approach with total sampling. The respondents were students aged 15-19 years from three high schools/equivalents in the catchment area of Poka-Rumah Tiga Health Center (SMKN 5 Ambon, SMAN 3 Ambon, and MA Al-Mabrur), with a total of 441 respondents. CED was determined based on the mid-upper arm circumference size being less than 23.5 cm. Logistic regression analysis was used to identify factors associated with CED in adolescent girls. Of the 441 adolescent girls who participated in this study, 45.80% were found to have CED. The odds of CED were lower in adolescent girls with normal BMI (18.5-22.9 kg/m2) (OR=0.09; 95%CI: 0.05-0.15; p<0.001) and overweight (≥23 kg/m2) (OR=0.01; 95%CI: 0.00-0.07; p<0.001) compared to those who were underweight (BMI<18.5 kg/m2). This study highlights the importance of conducting nutrition-specific and nutrition-sensitive interventions for adolescent girls. This includes raising the awareness and knowledge of adolescent girls, family members, and school teachers regarding the importance of balanced nutrition to reduce CED

Development of polypropylene fiber as concrete reinforcing fiber

The objective of this research is to produce polypropylene fibers with improved interface bonding with a concrete matrix. The Laboratory Mixing Extruder paired with the Randcastle fiberline drawing device was used for producing fiber from polypropylene (PP) chips. A target diameter of 0.5 mm fiber was obtained from a 2-stage process in the production line. The effort to improve the fiber surface by applying aluminum oxide sol-gel coating was unsatisfactory due to the failure of the coating materials to adhere to the fiber. Incorporating silica fume (SF) powder in the fiber extrusion process enhanced fiber properties. Silica fume co-extruded PP (SFPP) fiber has different characteristics in appearance, flexibility and surface roughness. Most importantly, the co-extrusions produced significance improvements in surface characteristics. Silica fume particles caused significant changes in the surface roughness of the fiber and contributed to the improved bonding performance in a cement-based matrix. The inclusion of the extruded fibers in a concrete matrix also improved the flexural toughness. Additional testing was conducted to examine the performance of extruded fiber in preventing plastic shrinkage cracking. Fiber reinforced mortar containing RPP and SFPP fibers were evaluated. Based on total crack area reduction efficiency, and crack width reduction efficiency SFPP fibers performed better than RPP fibers. These results indicate that the objective of developing a concrete reinforcing fiber using laboratory equipment was successfully achieved. The inclusion of silica fume particles in the extrusion process significantly changed the properties of the fiber and therefore contributed to the performance of these extruded fibers in the concrete matrix.Applied Science, Faculty ofCivil Engineering, Department ofGraduat

Development and testing of a weatherometer to accelerate the surface checking of wood

A new version of a weathering device (Accelerated Check Tester, ACT) was built, and weathering cycles for accelerating the surface checking of decking board samples exposed in the device were developed. The device permits the testing of realistic-sized decking board samples that are oriented horizontally and restrained in the device by screws. Two experiments were carried out to validate the device and associated test cycles. In the first experiment, southern pine (Pinus sp.) and western red cedar (Thuja plicata) samples were exposed to 6 different cycles in the ACT to determine which elements of weathering cycles (moisture, heat, freezing and UV radiation) were critical to the ACT’s function of accelerating checking. Large number of checks developed on the surface of samples subjected to wetting and drying cycles. Samples subjected to a cycle that also involved UV exposure developed significantly more and larger checks than samples subjected to any of the others cycles. Checking was much more pronounced in southern pine than in western red cedar samples. The second experiment examined the checking and distortion that developed in artificially weathered boards compared to those that developed in naturally weathered boards. Matched pairs of kerfed and unkerfed southern pine boards were subjected to accelerated weathering in the ACT or natural weathering. The number and length of checks that developed in boards exposed in the ACT were similar but not identical to those in boards subjected to natural weathering. The width of checks was greater in boards subjected to accelerated weathering. Kerfing had no significant effect on checking or distortion of boards. Exposure of boards in the ACT accelerates checking approximately 16 times compared to natural weathering. The Accelerated Check Tester should be a very useful tool for obtaining information on factors that affect the checking of wood.Forestry, Faculty ofGraduat
