Abstract

HYB SOHO, the Small Office Home Office concept is an integration between residential and office, which provides 2 floors in each unit, with a height of 7 meters from floor to floor, balconies in each unit, and other supporting facilities such as Gym, Jogging Track, and Swimming Pool. This concept produces a residence that offers a comfortable apartment as well as a home office. HYB = HYBRID The building concept in this design is a hybrid architecture that combines Jakarta's heritage architecture, buildings that have important cultural, historical, and social values, with modern architecture to create something new. Slipi, West Jakarta, is a strategic area with good accessibility. The location is close to the business center and offices in Central Jakarta and has easy access to various public facilities such as shopping centers, restaurants and public transportation. The SoHo (Small Office Home Office) Apartment in the Slipi area can be an attractive choice because of its large market potential.

Abstract

Tempe is a traditional Indonesian food with high nutritional value, particularly in its plant-based protein content. However, its market value remains relatively low when sold only in fresh form due to its limited shelf life, fluctuating raw material prices, and the lack of innovation in derivative products. This community service program was carried out to support the diversification of tempe products by applying appropriate technology for Tempe Jowo Household Industry (IRT), the partner. The implementation methods included problem observation, socialization, and training, as well as the application of technology through a slicing machine, an oil spinner, and a hand sealer for packaging. The results showed a significant increase in the partner's knowledge and skills, with the average post-test score rising from 60 to 82. More than 80% of participants were able to properly practice the production techniques for tempe chips, including slicing, temperature-controlled frying, and hygienic packaging. The application of appropriate technology improved production efficiency, reducing processing time by 30–40% compared to manual methods. The resulting tempe chips had a crunchier texture, better flavor, a longer shelf life, and more hygienic, attractive packaging. With product innovation and technological support, the partner IRT enhanced competitiveness and expanded market opportunities for modern retail and online platforms.

Abstract

Magnesium AZ31B is a promising biodegradable implant material due to its mechanical properties comparable to natural bone and its ability to degrade in physiological environments, potentially eliminating the need for secondary surgery. However, its rapid degradation can cause a significant loss of mechanical integrity, limiting its use in load-bearing applications. This study investigates the evolution of mechanical properties and surface characteristics of AZ31B during in-vitro immersion in Simulated Body Fluid (SBF). Tensile tests were conducted on triplicate specimens after immersion for 3, 6, and 9 days, while surface morphology and corrosion products were analyzed using SEM–EDX. In addition, pH variation and mass loss were monitored to evaluate corrosion behavior. The results show a progressive decrease in tensile strength from 279.77 ± 5.30 MPa (0 days) to 167.64 ± 2.31 MPa after 9 days of immersion, representing an overall reduction of approximately 40%. This degradation was accompanied by increased surface corrosion, mass loss, and solution alkalization. These findings provide quantitative insight into the relationship between corrosion progression and mechanical degradation of AZ31B, highlighting its time-dependent performance limitations and the need for surface modification strategies in biodegradable implant applications.
