UT Surabaya has a warehouse for storing spare parts needed either during heavy equipment maintenance work or customer demand in purchasing spare parts. This warehouse still does not maximize the existing capacity, seen from the many spare parts that are not arranged. This is due to the lack of shelf storage capacity due to the demand for many spare parts. In addition, the placement of spare parts that are not organized according to their group creates one of the problems, namely oil leaks that hit other spare parts. Seeing these problems, it is necessary to design a warehouse rack supported using the Ulrich Method by making three design concepts for selecting the most appropriate concept and in accordance with warehouse needs. Making design and structural strength analysis using Fusion 360 Software based on Finite Element Methods.

Concrete technology has significantly advanced and remains an interesting research topic. The demand for cement usage rises significantly due to concrete usage in various sectors. Cement production leads to air pollution issues and causes a greenhouse effect, even in the modern filtration era. Fly ash is an industrial waste that has been identified as a viable substitute for cement due to its pozzolanic properties. Silica Sand is sandblasting waste, where added value is needed. This study investigates the effectiveness of fly ash substitution in the cement portion of cementitious composite materials as an effort to minimize cement usage. Using sandblasting waste is an effort to implement 3R activity (reduce, reuse, recycle) for maritime waste. Compressive and tensile tests were evaluated in the variation of fly ash substitution for cementitious composite reinforced by coco fiber and wiremesh model. The results show that a 40% fly ash substitution gives the highest compressive strength of 32.98 MPa and the tensile strength of 5.90 N/mm². The best model composition provides the increments of compressive and tensile strength compared to the control specimen at 43.60% and 12.60%, respectively. ANOVA tests confirmed the significance of the enhancing effect as the presence of fly ash, both for compressive and tensile strength. Additionally, static analysis simulations using Fusion360 software were performed and indicated that the cementitious composite lawn table prototype’s design is safe and has good formability, as a safety factor performed 2.26, exceeding the required value of 2.00. This result explicates that fly ash and waste materials can be effectively used in cementitious composites for practical applications.

Effective machinery and supporting systems significantly influence production capacity, precision, and workflow continuity. In several companies, the lifting of hardened furan sand is still performed using forklifts, leading to delays and reduced efficiency, particularly during night shifts. This condition highlights the need for a more reliable material handling system. This study aims to design a conveyor system capable of transporting hardened sand to the sand crusher machine as an alternative to forklift-based handling. The conveyor is designed to match the height and spatial constraints of the existing sand crusher and can be operated without forklift assistance. The design process includes problem identification, product requirement definition, concept development, and concept evaluation. The results indicate that the second design concept provides the best performance, with a maximum stress of 60.729 MPa, supported by six structural frames, and a total manufacturing cost of Rp 37,923,000. The proposed conveyor system offers a more efficient and practical solution for material handling in sand-processing operations.
