Pesona Jamur farmer groups primarily focus on producing baglog and cultivating oyster mushrooms. Currently, they are doing business development by making a food product called oyster mushroom chips. This program aims at improving the quality of processed oyster mushroom chips by applying the appropriate technology of a spinner machine equipped with a magnetic contactor. The method used were practical training and assistance in processing oyster mushroom chips then dissemination of applied technology a spinner machine to the partners. The result of this program indicated that the oyster mushroom chip product processed by the Pesona Mushroom Farmers Group has a light brown color and the shape of the mushroom chips is not crushed. Oyster mushroom chip products are of higher quality than before the training activities because they had used the correct processing technique. The taste of the chips is also more savory, coupled with the complete form of chips, which are expected to attract consumers and increase product value. The correct chip processing technique and a spinner machine can minimize the oil content in oyster mushroom chips and expired dates. The product's expiration has increased from one month to four months without preservatives.

The development of the food processing industry carried out by MSMEs in Indonesia is still largely dominated by traditional processing systems. A problem occurred in terms of the need for much labor to require higher production processes. An example of MSMEs that currently in promising development is the cassava chips snack industry. Many employees involved in the cassava chips production process, long production process, and the cassava chips (lanting) produced is a lack of uniformity. This study aims to design and fabricate a lanting extruder machine with a capacity of 40 kg/hour with a 0.5 HP electric motor. The FEA simulation results with the loading of 490.5 N using Autodesk Inventor 2020 software showed a maximum Von Misses stress of 17.68 MPa, a displacement of 0.04 mm, and a safety factor of 11.7.

Salacca midrib fibers are abundant natural waste in Turi, Sleman Regency, Daerah Istimewa Yogyakarta. Cellulose Microfibers from the salacca midrib fiber has been isolated by mechanical treatment and successfully has good physical characteristics. Cellulose fibers with micro sizes can strengthen the bond effect between the matrix and the fiber due to the vast contact area. The method for isolated cellulose microfibers by mechanical treatment for speed rotation of 5000, 10000 and 15000 rpm. Mechanical stirrer treatment aims to fibrillation and reduces fiber dimensions because of their high rotation. The characterization by XRD, FTIR, and SEM. The XRD results showed that the mechanical stirrer treatment did not damage the crystallinity index of cellulose microfibers. The crystallinity index of the raw material is 64.3%, increased to 79.1% for the microfiber cellulose crystallinity index. Identification of functional groups using FTIR did not show changes in cellulose compounds resulting from mechanical treatment. Morphological observation of fibers by SEM shows that the diameter cellulose microfibers size obtained from salacca midrib fiber ranges 5-10 µm with 100-300 µm in length. Cellulose microfibers have potential materials as reinforcement in the micro composite and extraction into nanocellulose materials.

Stress analysis of the bender components in the design of the begel fabricator machine was carried out using FEA (Finite Element Analysis) with three variations of the constituent material parameters, namely 6061 aluminum, mild steel, and cast iron with a modulus of elasticity of 68.9 GPa, 220 GPa, 120.5 GPa, respectively. The test is carried out by a loading parameter 2520 MPa and fixed constraint. The maximum von misses stress and displacement obtained for each material parameter components using aluminum, mild steel, and cast iron are 17.78 MPa; 0.00765, 17.49 MPa; 0.00229, 17.62 MPa; 0.00427 respectively.
