Composite material could be developed into new material that would be useful for many interests. Fiber as composite raw material must be given pretreatment to improve the quality of composite. In this research, raw material for the composite was umbrella grass (Cyperus Alternifolius). A tool was designed to facilitate the processes of rolling or pressing, or abbreviated as roll press. Indeed, the design of roll press was preceded by designing the construction section that involved shaft, transmission system, bearing, pulley belt, and driver motor to move the roll. Result of rolling must be suitable for processing umbrella grass into the fiber of composite raw material. Testing was conduced to examine the work of the tool against the stalk of umbrella grass. Two testing was considered. First was testing against the variation of loads, which involved 10kg, 12kg and 14kg. Second test was against the variation of roll rotation at 160rpm, 197rpm and 280 rpm. Result of both tests provided specific fiber derived from umbrella grass that would be compatible to be composite material. Some results of research were indicated. Main drive motor was Â½ PK with rotation (n1) = 1430rpm. Pulley diameter (d1) was 75mm. Reducer system was signified by n2 = 831rpm and d2 = 129mm, and if d3 = 59mm was used, the outcome was n4 = 160rpm with d4 = 307mm. In case of bearing, its sliding moment was 0.309N.mm and tangent force was 2.06N. The frame of roll press tool was designed at the dimension of length x wide x height = 600mm x 320mm x 1200mm. The best parameter was 160rpm with load force of 10kg. By taking account all these results, it could be said that the result of roll press processing had successfully produced the fiber from umbrella grass into the suitable raw material for the composite.

Concrete is a discreet material that consist of aggregate as filler and cement paste (matrix) as binder. Both of them work together as a composite or monolithic mechanism, depends on the interface zone characteristic that developed by aggregate. Monolithic mechanism leading to failure catastrophically (brittle and instantly), while composite mechanism prevails failure occurs gradually. Monolithic mechanism maybe found in high strength concrete where hardness and stiffness of aggregate are compatible with their matrix. At the moment when the matrix tensile strength (ft) is reached. The cracks will propagate quickly cutting both aggregates and matrix, as well at once. Contrary to the composite condition, when the matrix tensile strength is reached, the aggregate will take over the load and the crack will propagate through the interface zone. The perspective of fracture mechanics and the failure parameters explain the mechanism of crack propagation based on the energy principles. This investigation reviews the phenomenon of concrete compressive strength with angular aggregates compared to rounded aggregates on cylindrical specimens with diameter (d) 15 cm and height (h) 30 cm of the same compressive strength. The difference between them, shows the tendency of the influence of the interface zone as traction, which significantly contributes to the performance capacity before collapse

Kegiatan abdimas ini bertujuan untuk membantu memberikan solusi atas masalah yang dihadapi oleh kelompok wanita tani (KWT) Mawar yaitu (1) peningkatan kapasitas produksi, dan (2) pencatatan keuangan. KWT Mawar mempunyai kegiatan utama menanam sawi. Saat ini, KWT Mawar berupaya untuk memenuhi pupuk tanaman sawi dengan memproduksi sendiri. Kotoran kambing yang menjadi bahan utama pupuk kandang diperoleh secara gratis dari peternak kambing. Kotoran kambing tersebut dihancurkan dengan tenaga manusia, sehingga hasil produksinya hanya mencapai 75 kg per bulan. Padahal kebutuhan pupuk sebesar 250 kg per bulan. Metode pelaksanaan abdimas ini adalah pembuatan mesin komposter elektrik, pelatihan penggunaan mesin komposter elektrik, dan pendampingan untuk pencatatan keuangan. Pembuatan komposter elektrik didasarkan dari hasil penelitian salah satu anggota Tim Abdimas. Mesin komposter elektrik ini dapat mempercepat dan meningkatkan kapasitas produksi pupuk menjadi sebesar 900 kg. Kelebihan produksi tersebut dijual ke anggota KWT Mawar dan non anggota. Penjualan ini memberikan konsekuensi logis bagi pengurus KWT Mawar untuk mengadministrasikan pencatatan keuangan secara akuntabel. Solusi atas permasalahan ke-2 adalah pendampingan penetapan harga pokok produksi dan pencatatan keuangan sederhana berbasiskan MS Excel. Penetapan harga pokok produksi menggunakan konsep target costing. Hasil pendampingan menunjukkan bahwa biaya produksi untuk kemasan pupuk 5 kg sebesar Rp 11.560. Harga jual ditetapkan sebesar harga pasar Rp 13.000 untuk kemasan 5 kg. Ini memberikan tambahan penghasilan sebesar Rp 187.200. Pencatatan keuangan sederhana berbasiskan MS Excel mengakomodir kebutuhan pengurus KWT dalam mencatat dana titipan anggota dari hasil penjualan sawi. Dana titipan ini akan dibagikan ke para anggota pada saat bulan Ramadhan.

Hydrogen is a fuel that is being developed today as a substitute for fossil fuels that are depleting. One way to produce hydrogen fuel is through the electrolysis method using a water-based HHO generator. This study aims to determine how much hydrogen is produced from each electrolyte solution, which is then compared to the area and color of the resulting flame. The comparison of each electrolyte solution comes from the ratio of moles of solute and solvent (H2O), which is 1:12, with the solutes used being NaCl, CH3COOH, and NaHCO3. The concentration of hydrogen gas produced is detected using the MQ-2 sensor. At the same time, the area and color of the flames are obtained through the results of a 20-minute combustion video, which is made into 100 photo frames for each electrolyte solution. The results of this study showed that the average hydrogen production for NaCl solute was 891.0 ppm and the flame area was 12.64 mm2 without blue color, the solute CH3COOH was 917.33 ppm, the flame area was 16.46 mm2 with 40.52% blue color, and NaHCO3 solute was 980.67 ppm with a flame area of 17.47 mm2 with 76.19% blue color
