Kelayakan Ekonomi Agribisnis Ubi Jalar di Desa Sei Beras Sekata Kabupaten Deli Serdang: Economic Feasibility of Sweet Potato Agribusiness in Sei Beras Sekata Village, Deli Serdang Regency
Sweet potato agribusiness has promising economic prospects for both producers and the country. For producers, it serves as a main source of income in rural areas, while for the country, it contributes to foreign exchange earnings due to the high demand in the international market. This study aims to analyze the feasibility of sweet potato farming based on the benefit-cost ratio (B/C) indicator. The research was conducted in Sei Beras Sekata Village, Sunggal District, Deli Serdang Regency. The population consisted of farmers cultivating sweet potatoes on leased land, with a sample size of 31 respondents selected using the census method. The results showed that the B/C ratio was 5.61, meaning that for every IDR 1 spent on farming costs, farmers received a benefit of IDR 4.61 per hectare. The magnitude of the B/C ratio is influenced by the level of income and farming costs. The study found that the income obtained was IDR 59,935,618/ha, while the total costs amounted to IDR 10,696,168/ha. Income was influenced by the quantity and price of production, while costs were affected by the quantity and price of production factors used in sweet potato agribusiness
The Diversification of Sea Processed Products to Increase Fishermen's Income in Brondon Village, Lamongan Regency
This community service activity aims to optimize the economic potential of marine catches in Brondong Village through product diversification assistance for micro-entrepreneurs which involves direct practice of processing mackerel fish into ready-to-eat food. Based on observations, it was found that even though the economic potential in this area is high, the community still uses traditional business patterns which results in low income for fishermen. The fundamental problem identified is the lack of processing of marine catches and product diversification. By using the Focus Group Discussion (FGD) method with a participatory approach to identify conditions, needs, problems and potential in village development. The results obtained from the pre-test assessment show that micro business actors' knowledge regarding product diversification is still low, with an average score of 65. However, after the training, there was a significant increase, where almost 90% of participants obtained a post-test score above 80 These results show that this mentoring activity has succeeded in increasing the knowledge and skills of micro business actors in diversifying seafood products, which is expected to increase fishermen's income and the welfare of the Brondong Village community
BIODIVERSITY OF ARACEAE IN MALABAR CITY FOREST, MALANG CITY, EAST JAVA
Indonesia, located on the equator with over 17,000 islands, is among the world's most biodiverse countries. Malabar City Forest in Malang serves as both a green space and a habitat for various plant species, including members of the Araceae family. Despite their roles in microclimate regulation, air purification, and soil stabilization, Araceae diversity in urban areas remains underexplored. This study aimed to identify and document Araceae species in Malabar City Forest and assess their ecological roles. Using an exploratory survey and cruise sampling, species were recorded based on their morphology. Field data were collected through direct observation aided by smartphone-based identification tools and validated with online taxonomic resources and literatures. Seven species were identified: Dieffenbachia seguine (Jacq.) Schott, Epipremnum aureum (Linden & André) G.S Bunting, Alocasia plumbea Van Houtte, Syngonium angustatum Schott, Syngonium podophyllum Schott, Epipremnum pinnatum (L.) Engl., and Typhonium trilobatum Schott, representing six genera. Their presence highlights adaptability to urban environments and potential as bioindicators. Future research should assess their ecological resilience and interactions. Local conservation through education, labeling, and habitat preservation can support biodiversity awareness and sustainable urban planning
CARBON ABSORPTION POTENTIAL IN MANGROVE ECOSYSTEM IN BORONGKALUKUA, MAROS REGENCY, SOUTH SULAWESI, INDONESIA
Mangrove ecosystems are essential in mitigating climate change through Carbon storage in sediments. This study aims to analyze the bulk density values, carbon concentration, and Carbon storage and absorption in mangrove sediments in Borongkalukua, Maros Regency. Sampling was carried out at five sediment depths (0-10 cm, 10-20 cm, 20-30 cm, 30-40 cm, and 40-50 cm) using the Loss on Ignition (LOI) method and analyzed statistically using one-way and two-way ANOVA. The results showed an average bulk density value of 0.33 g/cm³, with the highest value at a depth of 30-40 cm (0.28 g/cm³). Furthermore, the average Carbon concentration was 11.37%, with the highest value at a depth of 40-50 cm (20.50%) and the lowest at 0-10 cm (1.98%), with no significant differences between depths (p-value > 0.05). Meanwhile, Carbon storage in sediment reached 2,423.77 tons/ha. Total absorption reaching 8,895.23 tons/ha. In conclusion, sediment depth affects carbon accumulation, with higher carbon content in deeper layers due to the sedimentation process and minimal decomposition. This study emphasizes the importance of mangrove conservation in supporting Carbon storage and climate change mitigation
Urgency in The Existence of Publicness: Trans Jogja Bus Service as Public Transport in The Special Region of Yogyakarta
This research aims to see the extent of the existence of the Trans Jogja Bus as a mode of public transport in the Special Region of Yogyakarta. The publicness approach measures how public Trans Jogja Bus (BTJ) is in fulfilling the public interest and answers the urgency of overcoming congestion problems and providing services based on community needs. This research uses descriptive qualitative research, with data collection techniques of Interview, Observation, and Documentation. The informants who became data sources in this study include BTJ managers including PT AMI and Purasani pool, DIY Transportation Department, and BTJ service users. The results of this study found that the existence of BTJ in the public approach is as follows: 1) Service norms in BTJ's publicness degree are based on openness and socialization to the public, especially students. 2) Efforts to expand transport coverage on BTJ recipients, facilities, and route destinations. 3) The role of BTJ in reducing congestion is still not optimal because in operation it is often empty of passengers and congestion still occurs because private and online vehicles are the main choice for the community. 4) Efforts to build public trust in terms of organizational capability, leader quality, and passenger safety
Transformative Service and Public Satisfaction: Insights from Indonesia's Public Service Malls
This study examines the influence of transformative service dimensions on public satisfaction at the Public Service Mall (PSM) in Payakumbuh City, Indonesia. While PSMs have emerged as integrated service innovations, a significant gap remains in understanding how specific transformative service dimensions affect public satisfaction in developing countries. Employing an associative quantitative approach, this research collected data from 220 service users through structured questionnaires and analyzed it using multiple regression. The findings reveal that individual well-being dimensions contributed the highest impact (57.2%), followed by group well-being (51.2%) and social well-being (38.9%). Simultaneously, these three dimensions explained 88.7% of the variance in public satisfaction (F = 1704.067, p < 0.05). These findings make theoretical contributions by extending the Transformative Service Research (TSR) framework to public administration contexts in developing countries and by identifying a hierarchy of service dimensions that shape public satisfaction. From a practical perspective, this research provides policymakers with empirical evidence on the importance of balancing individual and collective well-being interventions in the development of PSM. This study addresses a literature gap by providing the first empirical evidence on TSR application in integrated public service facilities within a non-Western developing country context, specifically Indonesia
Pentahelix Collaboration as a Formulation for Combating Sexual Harassment in Higher Education: A Systematic Literature Review
Globally, the number of sexual disclosures (SH) in academia reaches 58%, the second highest after the military sector. This problem remains unresolved due to a lack of internal support and cross-sector mentoring. This study aims to formulate a Pentahelix collaboration model to mitigate SH in higher education. The research method uses a systematic literature review (PRISMA). The results show that a lack of understanding of gender equality and a culture of silence cause SH in higher education. Prevention of SH begins with policies that regulate and accommodate higher education for the benefit of victims. The main obstacle is the lack of understanding of gender equality and the evaluation of SH cases.
Additionally, limited mass media space is another obstacle. For the effectiveness of the policy, collaboration between the government, private sector, community, media, and academics is essential through the Pentahelix. The government is responsible for developing law enforcement, while other sectors are aware of the negative impacts of violence against children. The researcher proposes eight phases for policy implementation, starting from defining violence against children to assessing policies that have been implemented
Evaluating Nigeria’s National Development Plans: Addressing Contemporary Challenges and Seizing Strategic Opportunities
This study evaluates Nigeria's National Development Plans (NDPs) from historical and contemporary perspectives to identify challenges and strategic opportunities to enhance their effectiveness in achieving sustainable development goals. The research employs a comprehensive literature review and analysis of the implementation of Nigeria's NDPs. This approach assesses the socio-economic impact and institutional constraints that have influenced the effectiveness of these development plans. The study finds that Nigeria's NDPs have consistently faced several challenges, including corruption, weak institutional capacity, political instability, limited private sector involvement, and insufficient inclusivity. These factors have significantly impeded the effectiveness of the plans and their contribution to sustainable development objectives. To improve the implementation and impact of Nigeria's NDPs, the study recommends strengthening anti-corruption measures, enhancing institutional capacity, promoting policy continuity, increasing private sector participation, and improving inclusivity in the planning processes. Addressing these areas can lead to more effective development planning and achieving sustainable development goals

Pengaruh Efektivitas Sugar Labeling Pada Minuman Kemasan Terhadap Purchase Intention Mahasiswa
Penelitian ini bertujuan untuk menguji pengaruh efektivitas sugar labeling pada minuman kemasan terhadap intensitas membeli mahasiswa Fakultas Psikologi Universitas Padjadjaran angkatan 2024. Dengan metode kuantitatif eksperimental menggunakan desain between-participants pretest-posttest, sebanyak 63 mahasiswa berusia 17–20 tahun dibagi menjadi tiga kelompok: kontrol, label "High in Sugar," dan label "Guideline Daily Amount." Data diperoleh melalui kuesioner berbasis Theory of Planned Behavior yang memiliki reliabilitas sebesar 0,887, sehingga dianggap cukup andal untuk mengukur intensitas membeli. Analisis data dilakukan menggunakan uji Kolmogorov-Smirnov untuk mengevaluasi distribusi normalitas dan uji Kruskal-Wallis untuk menguji perbedaan rata-rata antara kelompok. Hasil penelitian menunjukkan bahwa tidak ada perbedaan signifikan pada intensitas membeli antara ketiga kelompok. Temuan ini menunjukkan bahwa pemberian sugar labeling belum cukup kuat untuk memengaruhi perilaku membeli mahasiswa secara keseluruhan. Faktor-faktor seperti kesadaran konsumen terhadap kesehatan, preferensi individu, kebiasaan membeli, dan sikap terhadap informasi label gula diduga menjadi pengaruh utama. Penelitian ini merekomendasikan penggunaan sampel lebih besar, variasi label gula yang lebih luas, serta cakupan lokasi penelitian yang lebih beragam untuk mendukung generalisasi hasil yang lebih baik pada masa depan
