One of the important contributions from the academic community of Brawijaya University is the empowerment of students in the boarding school setting. A range of empowerment programs have been adopted, encompassing the enhancement of traditional beverage production tools and workshop tools, as well as the introduction of handicraft innovations to augment income. The economy of the students and members of the Darul Mutaqin Islamic boarding school in Dau Village, Batu City, primarily relies on donations, supplemented by revenue generated from the sale of herbal goods. The school is strategically located next to rice fields, which offer ample natural resources. Food self-sufficiency can be achieved by utilizing animal husbandry techniques that involve feeding animals with nutritious green feed derived from agricultural waste, such as water hyacinth and maize stalks. This approach holds significant promise. Presently, the livestock industry at Darul Mutaqin Islamic Boarding School, namely in poultry farming, remains underdeveloped despite the ample availability of natural resources. Poultry farming, a generally manageable approach, might suffer a decrease in economic profitability if not adequately planned. The implementation of suitable technology via the Doktor Mengabdi initiative is anticipated to enhance students' proficiency in animal husbandry, augment livestock yield, and uphold environmental well-being. Darul Mutaqin's future goals include attaining financial self-sufficiency. This effort offers solutions by implementing a cutting-edge pilot project for a contemporary livestock system that integrates diverse mechanization and automation technology. The purpose of these suitable technologies is to generate sustainable poultry products, hence benefiting the pesantren community.

A coating is widely applied to protect base material during contact with surrounding. One important application in engineering is to protect a boat hull. The coating is applied to boat hull to prevent a decrease of mechanical properties of base materials particularly with corrosive seawater. Composite coating is applied since the composite coating provides better protection compared to paint coating. Additionally, sandblasting prior to composite coating is worked out to improve the mechanical properties of the coating. This work investigated the influence of the projection angle of the sandblasting process on the shear strength of the coated surface. The projection angle of sandblasting was varied from 30 to 90 Â°. The result shows that a higher projection angle decreases the strain strength of the coating surface. The experiment work showed that the shear strength of 30Â°, 45 Â°, 60 Â°, and 90Â°projection angle are 1.02, 0.66, 0.38, and 0.24 MPa, respectively.

The purpose of this study was to determine the effect of immersion time of NaOH at a temperature of 60-70 â„ƒ in wulung bamboo fibers on the tensile strength of the epoxy matrix composites. Wulung bamboo fibers (Gigantichloa Atroviolacea) have the potential to be used as reinforced in composites because they have high strength and are widely grown in Indonesia. In this study, bamboo wulung fiber reinforcement was used without treatment and with variations, soaking time 30 minutes, 60 minutes, and 90 minutes in 6% NaOH solution with a temperature of 60-70 â„ƒ. The composite manufacturing method used was vacuum assisted resin infusion and the standard composite specimen used as a tensile test was ASTM D638-01. The results showed that the longer the immersion time resulted in a rougher topography of the fiber surface which caused the composite tensile strength to increase due to the better mechanical interlocking between the fibers and the epoxy resin matrix. The wettability results on the fibers also show that the wetness between the fibers and the epoxy resin matrix is getting better, which is shown from the droplet contact angle on the resulting fibers. The highest composite tensile strength was obtained at 90 minutes immersion time of 169.765 MPa followed by immersion time of 60 minutes of 123.2 MPa, immersion time of 5 minutes of 81.7 MPa and without treatment of 71.6 MPa. Based on the results of the macro photo shows that the treatment given will reduce the failure of the pull out and debonding defects on the composite fracture.

Of many manufacturing processes, sand casting is one of the most widely used since there is no size limit of the workpiece. Big size product can be carried out at an affordable cost. In its process, sand casting comprises interconnected and complex series. If some of the processes are not properly carried out e.g. during solidification, will result in defects in the casting products. Simulation is an important method currently since it can model the entire metal casting process and show the dynamic character of the casting scheme. In this study, CAD is used for a 3D design on casting simulation. In this study, the grain size of molded sand, material quality and other process parameters were considered identical to all design schemes. This study aims to investigate the effect of varied design and dimensions of the gating system. It was found in this study that porosity and improper solidification were related to the improper gating and riser design.

Natural fiber composites are a good choice for many businesses uses because of their better mechanical properties and are friendly environment. Researchers are currently looking into bamboo petung fiber (BPF) and epoxy composites as alternative to synthetic fibers and products made from petroleum. This study's goal is to improve the overall performance of these composites while reducing the need for non-organic materials. This study used the various concentration of bromelain enzyme in BPF to changes the mechanical and physical properties of epoxy composites made from BPF. Composites were characterized the mechanical properties including tensile strength using tensile tester, impact strength using Charpy impact test, bending strength using three point bending methods, and surface morphology observation using scanning electron microscope. This study indicates that BPF composites that have been treated with bromelain enzyme have better mechanical properties. After being treated with bromelain, the BPF composite's tensile strength increase up to 59% with maximum tensile strength of 138.230 MPa, flexural strength increases up to 42% with maximum flexural strength of 135.58 MPa, and impact strength increases up to 64% with maximum impact strength of 4.88 J/m. The bond between the epoxy resin and the BPF makes the composite stronger. These results suggest that combining natural fibers and enzymes can make composite materials that work well and are strong.

This work investigates grape seed oil as a green substitute for conventional mineral-based cutting fluids to reach sustainable manufacturing methods. The application of grape seed oil as a cutting fluid in the machining of 316L stainless steel using the MQL method has not been documented in prior research studies. In this work, the study focuses on determining the effect of the grape seed oil on the surface integrity and comparing these findings to standard dry machining conditions by examining surface topography, roughness, and corrosion resistance at three different spindle speeds (1500, 1800, and 2100 rpm). Results of experiments showed that grape seed oil greatly improved surface quality and corrosion resistance. Surface roughness dropped noticeably by 61.6% at 1500 rpm as opposed to dry machining. Likewise, changes in surface roughness noted were 54.0% at 1800 rpm and 54.9% at 2100 rpm. Furthermore, the potentiodynamic polarization data show that the grape seed oil greatly prevents post-machining corrosion of 316 L stainless steel. The corrosion rates of the material face milled using grape seed oil were decreased by 78.6%, 74.6%, and 80.8% at spindle speeds of 1500, 1800, and 2100 rpm, respectively, when compared with dry face milling. These results indicate that grape seed oil demonstrates its ability as a cutting fluid even for high-speed machining operations. Hence, grape seed oil can address industrial demands for more environmentally friendly manufacturing methods.
