Phytotherapy for Diabetes: A Preclinical Study of Ethanol Extract of Winged Bean (Psophocarpus tetragonolobus L.) Leaves in Diabetic Rat (Rattus norvegicus) Models
The long-term use of synthetic hypoglycemic agents is known to cause adverse side effects and induce drug resistance. Winged bean (Psophocarpus tetragonolobus L.), a traditional medicinal plant from Maluku, contains secondary metabolites such as flavonoids, saponins, and tannins, which are believed to have potential in lowering blood glucose levels. This study aimed to investigate the effect of ethanolic extract of winged bean leaves on blood glucose reduction and β-cell regeneration in the pancreas of white rats (Rattus norvegicus) as a diabetic model. Thirty rats weighing between 150–200 g were divided into five groups: Group I (negative control), Group II (positive control), and Groups III, IV, and V (diabetic rats treated with ethanolic extract of winged bean leaves at doses of 2.52 mg/g BW, 5.04 mg/g BW, and 7.56 mg/g BW, respectively). Streptozotocin (STZ) was administered to Groups II–V to induce diabetes. Rats with blood glucose levels exceeding 200 mg/dL were subsequently treated with the designated doses of the extract in Groups III–V. On the final day, blood glucose levels were measured, and pancreatic organs were harvested for histological analysis. The results demonstrated that the ethanolic extract of winged bean leaves at a dose of 7.56 mg/g BW effectively reduced blood glucose levels in diabetic rats
Analisis Perbandingan Indeks Kemiripan Tanah pada Topsekuens Granit Gunung Sirimau Kota Ambon
This study aims to identify and describe soil morphological traits in the granite toposequence and analyze these traits to assess the similarity index between soil profiles. This study used a survey method involving transect observations and complete profile observations. Variable soil observations were made in a downward direction, following each change in slope segment on the granite toposequence. The results showed that Cambisol (Dystrudepts) soils developed with physical and chemical properties on three profiles for soil color ranging from yellowish brown to brownish yellow and yellowish red to red. The soil texture ranges from loamy sand to dusty clay, and the soil structure is rounded cubical. The soil has an acidic to slightly acidic pH and a slightly sticky consistency when moist and very low to low C-organic content. The similarity index assessed in the three profiles includes parameters such as dust/clay ratio, pH H₂O, and C-organic, which are very similar due to the similarity of the constituent rock formations

Women, Work, and Family: A Sociological Study on Female Income Contribution in Rural Maluku Communities
This study aims to analyze women’s economic contribution to household income and the dynamics of their dual roles within rural communities in Maluku, particularly in Sawai Village. Although men are traditionally recognized as primary breadwinners, socio-economic transformations have encouraged women to engage in productive activities such as farming, trading, tailoring, and public employment, yet their contributions remain socially and statistically undervalued. Using a qualitative approach within the framework of economic sociology and gender studies, this research employs in-depth interviews, participant observation, and social documentation, analyzed thematically through categories of economic contribution, domestic roles, social perception, and gender adaptation. The findings reveal that women in Sawai play a significant role in sustaining household economies, contributing an average of 28.38% to total income, with the highest contribution (42.70%) coming from formal employment. These results indicate a shift in the gendered division of labor, as women become integral to household economic structures despite limited social recognition under prevailing patriarchal norms. The study’s novelty lies in applying a locally grounded economic sociology perspective to postcolonial rural Maluku, integrating quantitative and qualitative insights. Theoretically, it advances discourse on gendered economic participation, while practically offering policy implications for culturally sensitive women’s economic empowerment in Indonesia’s eastern rural contexts
SOSIALISASI PAKAN ALTERNATIF BERBASIS TEPUNG MAGGOT SEBAGAI SUMBER PROTEIN UNGGAS DI DESA MOROME KECAMATAN KONDA KABUPATEN KONAWE SELATAN
The high and fluctuating cost of poultry feed has become a major constraint for smallholder farmers in Morome Village, Konda Subdistrict, South Konawe Regency. This condition undermines the sustainability of poultry farming and reduces farmers’ profit margins. One potential solution is the utilization of maggot (Hermetia illucens / Black Soldier Fly) meal as an alternative protein source that is environmentally friendly, economically viable, and can be locally produced from organic waste. This community service program aimed to enhance farmers’ knowledge and skills regarding maggot farming, processing into meal, and formulating alternative poultry feed. The implementation methods included participatory observation, interactive lectures through presentations, leaflets, and videos, followed by demonstrations and hands-on training on maggot farming and meal processing. The results showed that participants’ understanding of maggot as poultry feed increased, along with their technical skills in maggot cultivation and processing. Farmers also became more motivated to utilize organic waste as maggot rearing media. Strong enthusiasm was evident through active participation in practice sessions and group discussions. Therefore, this program successfully promoted the adoption of maggot-based alternative feed innovation, supporting both cost efficiency in poultry production and sustainable waste management
