Abstract

This study aims to identify the potential utilization of banana stem fiber (BSF) as a locally sourced composite material to support building infrastructure in North Maluku. The research focuses on analyzing the tensile and impact properties of the composite. An experimental method was used, incorporating different treatment durations for the fibers by immersing them in liquid smoke for 1, 2, and 3 hours. The treated fibers were then heated at 40°C for 30 minutes. The next step involved fabricating BSF-reinforced composite specimens by preparing the resin and fibers, with a fiber length of 10 mm and a composition of 30% BSF and 70% resin. Tensile and impact tests were conducted to evaluate the mechanical properties of the composites. The results showed that the tensile strength of the P3J composite increased to 88.351 MPa, representing a 3.79% improvement compared to the untreated composite (TP). Meanwhile, the impact strength showed the highest increase after 1 hour of immersion, reaching 10.911 KJ/m, which is 25.45% higher than TP. These findings indicate that liquid smoke treatment enhances the tensile and impact properties of the composite.

Abstract

Soft subgrades with shear strength, cu of 10 kPa to 25 kPa are given low bearing capacity and high settlement. Local government has been built infrastructure of embankment such unpaved road on the soft subgrade by using timber and bamboo materials (called “Cerucuk”) are very familiar for Indonesian local people. By developing load capacity of floating pile type, bamboo pile cluster was applied for Tol road in North the Java Island. However, bamboo material limited of life construction inside the soft ground, and exploitation of timber pile was violated environmental issue. Therefore, this research method is developed a new geometrical small - cluster pile by using concrete from local material or Igneus stone such as gravel and sand produced in quarry Ternate Island. Ultimate bearing capacity of single small - cluster pile installation modelled in soft subgrade tank. Then, observed by several block concretes and it is presented by empirical formulae. Finally, the ultimate load capacity of small-pile cluster in soft subgrade is obtained Qu of 15.92 kN and 19.79 kN for observation and calculation, respectively. Rearrange of piles can be increased load capacity of small-cluster pile in soft subgrade as spacing single pile by spacing 5Deq to 3Deq. Mostly load capacity of small-pile clusters should be calculated by using empirical method to provide bearing capacity based on geotechnical rule with laboratory and field soil investigation data and load standard for unpaved roads.

Abstract

Desa sokonora merupakan desa yang berada di kabupaten Halmahera Utara, dengan kondisi masyarakat prasejehtera, kondisi penduduk yang berprofesi sebagai petani banyak membutuhkan teknologi-teknologi sederhana untuk menunjang aktifitas mereka, sehingga Perguruan Tinggi memiliki tanggung jawab moral dalam menjawab kebutuhan masyarakat tersebut Melalui program pengabdian tahun 2024 pelaksana akan melakukan penguatan elemen masyarakat dalam pelatihan dan transfer tekonolgi mesin parut kelapa mini dalam menunjang aktifitas masyarakat.Untuk mengetahui peningkatan pemahaman kelompok mitra, dirancang suatu evaluasi yang dilakukan di awal (pre test) dan akhir kegiatan (post test). Berdasarkan hasil kuisioner post-test sebanyak 90% peserta telah mengetahui atau pernah mendengar mengenai mesin parut kelapa mini dari sebelumnya 35% belum mengetahui, sebanyak 90% peserta pernah mendengar tentang mesin parut kelapa mini dari sebelumnya 25% peserta belum pernah mengetahuinya, 90% peserta memiliki keinginan untuk menggunakan mesin parut kelapa mini, 90% peserta sudah mengetahui prinsip kerja mesin parut kelapa mini, 100% peserta mengetahui prosedur penggunaan mesin parut kelapa mini, 90% peserta yang megetahui bahan membuat kompor alternatif.

Abstract

The 2022 PKM activities carried out by the Mechanical Engineering Study Program, Faculty of Engineering, Khairun University, were completed in Takofi Village, Pulau Moti District. Takofi Village is one of the villages located in Pulau Moti District, with the average population working as farmers and fishermen. One of the biggest fertilizer producers from this village is cloves and nutmeg. The clove and nutmeg home processing industry in this village can be said to be very minimal. The clove and nutmeg marketing process carried out by the people of Takofi Village is usually carried out individually by the farmers and then sold to Village collectors; there are also itinerant traders who come from door to door to buy dried cloves from clove farmers who want to sell their cloves to them and some are sold directly to Ternate. The dedication results show that partners easily understand and practice the training material. This is evident from their ability to make several processed clove and nutmeg products, such as making clove oil and processed nutmeg products into candied nutmeg as taught. Through this activity, partners can be motivated to become entrepreneurs by utilizing existing local potential. Thus, the existing natural resources can not only be used optimally but also can generate added value for the family economy.Keywords:  Cloves, Nutmeg, Community Empowerment, Takofi Village.
