GAMBARAN BODY IMAGE, MINORITY STRESS, DAN GAY COMMUNITY STRESS LAKI-LAKI HOMOSEKSUAL DI JAKARTA
Full text linkThis study explores the experiences of body image, minority stress, and gay community stress among homosexual men in Jakarta. Previous research suggests that homosexual men are more vulnerable to developing negative body image, with their sexual identity and involvement in the gay community creating additional layers of complexity in this process. Employing a qualitative approach with thematic analysis, data were gathered through semi-structured face-to-face interviews with four participants in their early twenties, all of whom identified as homosexual men over the age of 18 and represented diverse social backgrounds and community experiences. The findings show that body image formation is shaped by minority stress and gay community stress, both of which reinforce the idealization of masculinity. Minority stress stemmed from heteronormative cultural pressures that position masculinity as the normative ideal, while gay community stress originated within the community itself, where masculine bodies are often valued as the primary marker of social and sexual desirability. This dual pressure to appear masculine generated internal conflict which, when unmet, resulted in anxiety, feelings of undesirability, and negative self-evaluations about their physical appearances, further intensified by social media and dating applications. These findings highlight the importance of addressing the psychosocial experiences of homosexual men to inform more inclusive interventions

Rancang Bangun Alat Pencahayaan Terkontrol Berbasis Motor Stepper Dan Railing untuk Studio Fotografi
Full text linkPhotography studios often require various lighting arrangements for different photo and video shooting themes. Lighting in a studio environment is critical to producing high-quality images and videos. However, conventional lighting sources, such as lamps or other lighting equipment, are often inflexible to reposition according to the photographer’s desired thematic setup. Manual lighting adjustments can be time-consuming, mainly when automated positioning features are unavailable. This inefficiency hampers the photo and video shooting process. In the community service program discussed in this article, the team from the Mechanical Engineering Department at Atma Jaya Catholic University of Indonesia developed a motorized stepper-based lighting system with railing to address the inefficiencies in studio lighting adjustments. The team partnered with Kolaborasi Berkat Kreasindo (KBK) studio. The developed lighting system can be controlled remotely, eliminating the need for direct manual adjustments. This solution has assisted the partner studio in enhancing the lighting setups for photography sessions
Spatial Planning Politics in Determining the Location for the Construction of a Waste-To-Energy Power Plant (PLTSa) in Makassar City, Indonesia
Full text linkThis research analyzes the political dynamics in determining the location for the construction of a Waste-to-Energy Power Plant (PLTSa) in Makassar City. Although existing regulations, such as Makassar Mayor Regulation No. 1 of 2021 and Makassar City Regional Regulation No. 4 of 2015, have designated the Tamangapa Landfill as the construction site, the city government instead proposed an alternative location in the Tamalanrea District. This has sparked controversy among the community, the Regional People's Representative Council (DPRD), and business actors, as well as causing conflicts of interest among various stakeholders. With a descriptive qualitative approach, this research reveals that spatial planning decisions are not only influenced by technical and environmental aspects but also by political and economic considerations. The shifting of development locations reflects the contestation of power in urban spatial governance, where the interests of political elites and investors are often prioritized over the aspirations of the community. This research highlights the importance of transparency and public participation in spatial planning to avoid social conflicts and ensure spatial justice in infrastructure development policies
