Social capital can be one of the factors or forces that support the empowerment process in the community. This article aims to describe the role and elements of forming social capital in the management of BUMG in Trieng Gadeng Village, Darul Aman District, East Aceh. The qualitative method used and data obtained from observations, interviews, and literature studies. The results of this study indicate that the types of social capital in the management of BUMG are bounding and linking. Geuchik as an actor, support both types of social capital. Geuchik's leadership can make the elements of social capital work effectively, such as building trust between various parties, running the BUMG program following local norms, and building social networks. So, the social capital plays a role as a driving force for the birth of cooperation between the government, BUMG managers, and the community in the success of the program set by BUMG in Trieng Gadeng Village, East Aceh. Abstrak Modal sosial dapat menjadi salah satu faktor atau kekuatan yang mendukung proses pemberdayaan di dalam masyarakat. Artikel ini bertujuan untuk mendeskripsikan tentang peran dan unsur-unsur pembentuk modal sosial dalam pengelolaan BUMG di Gampong Trieng Gadeng, Kecamatan Darul Aman, Aceh Timur. Metode yang digunakan adalah metode kualitatif, dan data diperoleh dari hasil observasi, wawancara, dan studi literatur. Hasil penelitian ini menunjukkan bahwa tipe modal sosial dalam pengelolaan BUMG adalah bounding dan linking. Kedua tipe modal sosial tersebut ditopang oleh seorang aktor yaitu pak Geuchik. Kepemimpinan Geuchik mampu membuat unsur-unsur modal sosial berjalan secara efektif seperti membangun kepercayaan antar berbagai pihak, menjalankan program BUMG sesuai dengan norma setempat dan juga membangun jaringan sosial. Dapat dinyatakan bahwa modal sosial berperan sebagai pendorong lahirnya kerjasama antara pemerintah, pengelola BUMG, dan masyarakat dalam menyukseskan program yang telah ditetapkan oleh BUMG di Gampong Trieng Gadeng, Aceh Timur.

Subterranean termites Coptotermes curvignathus has found as pest in oil palm plantation. The research aimed to control the termites in oil palm plantation using Hexaflumuron bait with different dosage. Location of research was oil palm plantation at Purun village in Mempawah Regency. The study was conducted by a completely randomized design method. The research treatment was dose of Hexaflumuron termite bait, consisting of 30 gram and 60 gram. Three blocks was choosing as a sample treatment consists of block H 35, block H 38 and block H 39. Hexaflumuron bait has weight 30 gram. Treatment dose of 30 gram was conducted with lay down the bait of Hexaflumuron at the mud tunnel of termites in the trunk of oil palm. Treatment dose of 60 gram was conducted with lay down two bait of Hexaflumuron at the mud tunnel of termites in the trunk of oil palm in the different place. Then inspection of bait consumption was conducted every week. Data of bait consumption and termites elimination was collected. Results of the research showed that Hexaflumuron bait was consumed by termites up to 100%. The bait has attracted the termites to consume and non-repellent to termites. After four until seven week consumption the Hexaflumuron bait, termites eliminated from the oil palm. The result of variance analysis showed that there was no significance difference between the dose of 30 gram and 60 gram on the termite consumption level. Hexaflumuron bait was effective for termites elimination in oil palm plantation within four until seven weeks and dose 30 gram was optimum for termites elimination. PENDAHULUANRayap merupakan serangga yang mendekomposisi selulosa yang terdapat pada kayu. Peranan rayap sangat penting di alam karena rayap membuat tanah menjadi lebih subur sebagai hasil dari proses dekomposisi serasah yang dilakukan oleh rayap. Namun rayap juga dikenal sebagai hama bagi tanaman perkebunan kelapa sawit. Beberapa peneliti menyatakan rayap menjadi hama yang merugikan di perkebunan kelapa sawit, dan jenis yang ditemukan meliputi Coptotermes curvignathus Holmgren, Schedorhinotermes javanicus, Macrotermes gilvus dan Microtermes sp

The heat absorbability and the efficiency of water heaters are increased by adding phase change material as heat storage in solar water heaters known as cylindrical through collectors type. It used to absorb heat from solar energy and will concentrate towards an absorber pipe containing water, so it can increase the water temperature that flows through the tube. In this study, two absorber copper pipes used with Ø 2.54 and Ø 1.91 cm, respectively. The copper pipes arranged parallel and placed the heat storage materials with different conditions. A drum with a diameter of 55.5 cm and a length of 10 cm is split vertically into two parts which will be used as a cylindrical type of solar collector — the solar intensity measured during the experiment. Results show the highest water out temperature is 65 °C at 13:00 WIB that the position of paraffin inside pipe 2 with a solar intensity is 1195 W/m2 and the efficiency is 13.5%. The water inside of pipe 2 found the water out temperature is 62 °C and the efficiency is 12.31%. The position of air inside of pipe 2 recorded the water out temperature is 60 °C, and the efficiency is 10.21%. It can be concluded that the effect of adding paraffin inside of pipe 2 is better than water and air.

The paper reported the study on the tensile strength of polymer composite reinforced with abaca fiber and polyester matrix. The effect of fiber weight content and fiber orientation on the tensile strength of the abaca composite were investigated in the study. The abaca composite panel was fabricated using press method with 3 levels of the fiber weight content (20%, 30% and 40%) and 3 levels of fiber orientation (00, 450 and 900). The tensile specimen was prepared according to ASTM D3039 standard. The tensile test was conducted using MTS Landmark servo hydraulic testing machine with a tensile speed of 2 mm/min. The result of the experiment showed that both of fiber weight content and fiber orientation gave significant effect on the tensile strength of the abaca composite. The highest tensile strength was 61.9 MPa, produced by the abaca composite panel with fiber weight content 30% and fiber orientation 00. According to the standard, the tensile strength has fulfilled the requirements as a non-structural material.
