Abstract

The methyltestosterone hormone is a synthetic hormone of androgen and has been used to obtain the juveniles of male mono-sexual fish such as Tetra Congo, Tilapia, and Betta. The methyltestosterone use on gourami has not maximized. It because there is no data on the exact age of larvae to produce maximum male mono-sexual juveniles, so it is necessary to do research on the effect of methyltestosterone hormone on the age of gourami larvae on the success of male mono-sexual formation and get the right larval period to obtain maximum survival gourami. The methods of this research were conducted using a completely randomized design with four treatments of the age of gourami larvae aged ten days, 15 days, 20 days, and 25 days. Each procedure was repeated three times. Data analysis used ANOVA analysis and LSD test. The larvae are soaked in a solution containing 5 ppm of hormones for 24 hours. The results showed that the administration of the hormone methyltestosterone to gourami larvae (Osphronemus goramy Lacepè¨de, 1801) with different ages had a very significant effect (P <0.01) on male sex formation with the highest average percentage of males obtained in treatment B (15-day larvae age) that is equal to 82.33% and the lowest in the treatment of larval period of 10 and 20 days is 74.00%.

Abstract

Minyak jelantah menjadi masalah lingkungan dan kesehatan yang serius di kalangan rumah tangga Indonesia, dimana hanya 30% yang didaur ulang secara tepat. Perempuan sebagai pengelola domestik paling rentan terhadap dampak kesehatan dari penggunaan minyak berulang, sementara potensi ekonomi dari limbah ini belum termanfaatkan secara optimal. Pengabdian ini bertujuan untuk memberdayakan perempuan melalui pelatihan daur ulang minyak jelantah menjadi sabun bernilai ekonomi, sekaligus meningkatkan kesadaran gender tentang peran perempuan dalam ekonomi berkelanjutan. Metode pelaksanaan meliputi pre-test, sosialisasi dan penyuluhan, pelatihan praktik langsung, serta post-test untuk evaluasi pemahaman peserta. Kegiatan dilaksanakan pada 29 September 2025 dengan partisipasi 14 peserta. Hasil evaluasi menunjukkan peningkatan signifikan sebesar 23,7% pada aspek pengetahuan, keterampilan, dan kesadaran ekologis peserta. Pemahaman terhadap bahaya minyak jelantah meningkat dari rata-rata 2,10 menjadi 4,00, sedangkan keterampilan teknis pembuatan sabun meningkat dari 3,10 menjadi 3,64. Pasca pelatihan, 50% peserta memanfaatkan keterampilan untuk kebutuhan rumah tangga, 35,7% berencana memproduksi untuk dijual, dan 14,3% akan mengajarkan kepada orang lain. Program ini berhasil mencapai target 100% dan selaras dengan SDG 3 (Kehidupan Sehat dan Sejahtera), SDG 5 (Kesetaraan Gender), dan SDG 12 (Konsumsi dan Produksi Bertanggung Jawab). Kegiatan ini membuktikan bahwa pemberdayaan perempuan dalam pengelolaan limbah rumah tangga dapat menjadi strategi efektif untuk meningkatkan kesejahteraan ekonomi, kesehatan, dan keberlanjutan lingkungan.

Abstract

Atauro Island has been highlighted in various studies that emphasize its ecotourism potential and natural beauty. However, very few studies specifically discuss women’s contributions to local development, especially through non-formal education that encourages creativity and economic empowerment through handicrafts. This study aims to analyze how the role of non-formal education in empowering women through the production of Boneca de Atauro handicrafts on Atauro Island, Timor-Leste. Using a qualitative approach and descriptive methods. There were 52 women who involved in this study. Data were collected through observation, in-depth interviews, and documentation. The results of the study indicate that amidst limited formal support from the government, women craftspeople are able to build economic and social capacity through community-based learning, intergenerational mentoring, and the use of local wisdom. This process not only strengthens cultural identity but also creates sustainable economic opportunities. This initiative also supports the achievement of the Sustainable Development Goals (SDGs), especially in the fields of education, gender equality, and local economic growth. This study confirms that non-formal education is a strategic pathway for grassroots-based development in remote areas.

Abstract

Road infrastructure development plays a crucial role in improving regional connectivity and economic growth; however, its implementation continues to rely predominantly on conventional gray infrastructure that often neglects ecological sustainability. Although previous studies have extensively examined green infrastructure from engineering and environmental perspectives, limited attention has been given to the educational processes through which ecological character can be developed among infrastructure stakeholders. This study investigates how ecological character education can strengthen environmentally responsible road infrastructure planning. Specifically, it aims to (1) examine the educational dimensions of ecological character among stakeholders involved in road development, (2) identify the internal and external factors influencing ecological character development, and (3) formulate education-based strategies using SWOT analysis. A descriptive-analytical mixed-methods case study was conducted along the Kepanjen–Pagak Road Section, Malang Regency, Indonesia. Data were collected through interviews, field observations, questionnaires, and document analysis involving government officials, planning consultants, academics, infrastructure practitioners, and community representatives selected through purposive sampling. Qualitative data were analyzed thematically, while quantitative data were examined using the Internal Factor Analysis Summary (IFAS), External Factor Analysis Summary (EFAS), SWOT, and Quantitative Strategic Planning Matrix (QSPM). The findings reveal that ecological character development is shaped by ecological literacy, environmental values, institutional commitment, stakeholder collaboration, and participatory planning, but remains constrained by conventional gray infrastructure practices, weak inter-agency coordination, and limited environmental integration in planning. The IFAS score of 2.72 and EFAS score of 2.82 positioned the study in Quadrant I, indicating strong internal capacity and favorable external opportunities to implement proactive education-oriented strategies. QSPM analysis further identified the Strength–Opportunity (SO) strategy as the highest-priority alternative for integrating ecological character into sustainable road governance. This study contributes to the literature by extending ecological character education beyond formal educational settings into infrastructure governance and professional practice. It also proposes an education-based strategic framework that supports stakeholder capacity building, sustainability competencies, and environmentally responsible infrastructure planning within the broader context of Education for Sustainable Development (ESD).
