The shoes selection as the right footwear is very related to the feet comfort, especially in the selection of shoe materials. The shoe consists of three parts: insole, outsole, and upper shoe. The right outsole material will affect the comfort of feet during activity. This paper demonstrates a mechanical testing method on optimization of outsole material based on computer aided engineering (CAE). The outsole design on milutes diabetic patients in previous studies used as the basic design for mechanical testing at CAE. Three types of mechanical testing on Abaqus software 2016: bending, torsion, and plantar plessure used in this paper to determine the optimal outsole material as outsole material shoe orthotik. The test results showed that the material EVA rubber type declared with optimum characteristics of the von mises stress 0.0013 MPa, maximum principal stress 0.0036 MPa and features shock absorption of 5.01562 mJ. This data can served as a basic reference for the process of manufacturing the outsole of shoe on CNC machines.

Moyudan Subdistrict is an area that has several small industries of chicken farming. Partner who was the participant of this community service program, Prayogo’s Chicken Slaughterhouse, an SME in Yogyakarta, had a major obstacles to increase the production capacity of good, neat, clean, and hygienic chicken meat and meeting halal standards. In addition, this business still did not have chicken cutting standards according to factory standards (SNI 01-6160-1999). The cutting process was still done manually and conventionally, with mediocre quality and quantity. Production capacity was low, and many production operators experienced high fatigue in the hands and shoulders or experienced musculoskeletal fatigue. The expected transfer of technology in this program is the design of modifications to poultry cutting machines that suit the needs of this partner and is associated with the selection of portable poultry machine designs and manufacturing technologies that can later improve the quality and capacity of chicken meat processing according to halal standards. The results of this community service activity are; (1) one unit of portable poultry machine given to partner; (2) an increase in production capacity of 429% in terms of cutting capacity per day with smooth, precise, and accurate cutting quality; (3) reduced fatigue experienced by the production operators after the machine in operation. The chicken cutting capacity of Prayogo's Chickens Slaughterhouse can be increased by 4.29 times from 75 chickens a day to a maximum of 321 chickens a day.

Club foot is one of the foot deformities caused by genetic factors. Patients with this characteristic have abnormal foot shape. Daily activities cannot be carried out by patients properly. The most important difficulty is finding shoes as the right footwear, precision and comfortable to use. The number of patients who are not small in Indonesia is an important topic discussed in this paper. Semi-Reverse innovative design (RID) is a Reverse Engineering application with 3D mesh data and able to get the precise and accurate surface contours of the club foot patient. Computer Aided Design (CAD) PowerShape 2019 was used in this paper to get a variation of the design of an orthotic ankle foot insole that fits the club foot patient's foot. The resulting output is in the form of three types of insole designs with geometric error tolerance of 0.08 mm.

The ceramic tile wall is a decorative element used inside restaurants, museums, hotels, aristocratic residences, and places of worship. It plays a critical role in the development of a structure with strong personality and unique qualities by providing relief patterns specific to history or era. The demand for distinctive ornamental wall ceramics that can be mass produced with precision and accuracy has been a challenge for numerous ceramic enterprises in Indonesia, which have historically relied on the skills of artistic professionals in a handmaking process. The purpose of this research was therefore to develop and apply a ceramic tile design process that integrates computer design and fabrication methods with traditional ceramic production techniques. Using the ArtCAM 2015R2 software, photos of batik and Islamic themes were effectively converted into a 2.5D computer-aided design model. Additive manufacturing technology was then used in conjunction with Objet30 Pro 3D printer to precisely produce master molds with Islamic nuances such as puzzle and floral patterns, then conventional ceramic fabrication technology was employed to produce ceramic tiles using these molds. By combining computer-aided design and rapid prototyping technologies, a variety of exact and detailed Islamic decorative ceramic wall tiles were produced with dimensional accuracies within 2.00 mm. Furthermore, the proposed approach demonstrated a 90% reduction in design-to-production time from to 10–12 months to roughly 1–1.5 months.
