ABSTRACT Hybrid natural-natural fibre reinforced polymer composites become attractive alternative to seek the friendly-environmentally materials. Study on the durability level of the hybrid composites have the importance reason due to the role in application as structural function. This study focuses on examining the fatigue strength of polypropylene polymer composites reinforced with hybrid sugar palm-kenaf fibres. The hybrid composite materials were prepared by mixing the fibres and matrix with several compositions. There are five composition types of specimens that evaluated, such as 70:10:10, 70:15:15, 70:20:10, 80:10:10 and 90:5:5. The hybrid composites were composed by PP, sugar palm fibre and kenaf fibre. Furtheremore the tensile test were conducted to find the value of ultimate tensile strength for every specimens of hybrid composites. The fatigue test also were conducted with four level of stress i.e. 80%, 70%, 60% and 50%. The results show that in the lower level of stress, the hybrid composites with higher content of sugar palm fibre posses the better performance of fatigue life compare to the others

This research aims to discuss the forms, causes, and effects of poverty as expressed in the novel Kembara Rindu. This research uses descriptive literary research methodology, by observing words, phrases, clauses, and sentences related to poverty in the novel. The data collection techniques used include reading and understanding the novel, recording relevant data, and organizing them based on the research questions. Data analysis consisted of several stages: (1) identifying data related to the form of poverty; the causes of poverty, and its impact in the novel, (2) analyzing the collected data, and (3) presenting conclusions related to the issue of poverty in the form of a thesis. The findings of this study reveal that the forms of poverty found in the novel are absolute and relative poverty. The factors that cause poverty are the low quality of the labor force, difficult access to capital ownership, low technological capabilities, and inefficient use of resources. The effects of poverty are unemployment, crime, school dropouts, and difficult access to health.

This study investigates the fatigue behavior of sugar palm fibre (SPF)-reinforced thermoplastic polyurethane (TPU) composites with varying fibre contents (10 wt%, 20 wt%, and 30 wt%). The composites were fabricated using extrusion followed by hot press moulding. Tensile tests were conducted in accordance with ASTM D638 to determine the ultimate tensile strength (UTS), and fatigue tests were performed under stress levels of 80%, 70%, 60%, and 50% of the UTS, following ASTM D7791. The results indicate that an increase in fibre content leads to a reduction in both tensile strength and fatigue life, likely due to poor interfacial bonding and fibre agglomeration. Fatigue life was found to be significantly higher at lower stress levels across all fibre contents. These findings provide valuable information about the potential and limitations of SPF/TPU composites for applications involving cyclic loading, particularly in lightweight and sustainable material applications

This study was focused on the characterize the hibridisation of kenaf and sugar palm fibre in reinforcing the polypropylene matrix. Addition of MAPP (Maleic Anhydride Polypropylene) was used as compatibilizing agent with variation of 2%, 3% and 5%. The specimen materials were prepared with 30% amounts of fibres while the ratios between kenaf and sugar palm fibre are 10:20, 15:15 and 20:10. The composites were fabricated using melt mixer technique and followed by compression molding process. The specimens were cut according ASTM Standard D790 for conducting the flexural testing. After testing done, the results shown that flexural strength of composites tend to decreased when the content of MAPP increased. The ultimate flexural strength was attained at 2% MAPP addition of the hybrid composites with 20% kenaf fibres. Among the composites with different ratios, the hybrid composites that contain more kenaf fibres exhibit the higher value in flexural strength than the composites that contain more sugar palm fibres.

This community service aims to improve care, maintenance and repair of submersible water pumps spread across Gampong Luthu Lamweu, Aceh Besar Regency, Aceh Province. Activities begin with the preparation stage, site feasibility survey, identification of problems with partners, implementation of activities, as well as socialization and evaluation of results. Problem identification is carried out through maintenance, upkeep and repair steps for water pumps, which are delivered through training and technical assistance by the PKM implementation team to participants, with the aim of ensuring that participants are able to independently manage and maintain the water pump system. The repair process focuses on components that can be repaired, while for damaged components, they are replaced with new spare parts. Evaluation is carried out at the final stage of activities to ensure that the water pump is functioning optimally and water distribution is running normally, so that the availability of water for agricultural and rice field needs can be guaranteed. This activity was carried out successfully, as evidenced by the appreciation received from the participants, especially local farmer groups, which showed their level of satisfaction and pride in their success in independently managing the maintenance and repair of water pumps.
