Mocaf Flour for Food Security, Stunting Alleviation, and Creative Economy: ASystem Thinking Approach
Full text linkThe rising dependence on imported wheat flour in Indonesia highlights the need for local alternatives such as Mocaf (modified cassava flour). This study explores the potential of Mocaf production in Sindangsuka Village, Garut, to strengthen food security, reduce childhood stunting, and promote the creative economy. A systems thinking approach was employed using a Causal LoopDiagram (CLD) to map and analyze the dynamic interconnections among these three domains. Data was gathered through literature review, focus group discussions (FGDs), and interviews with key local stakeholders. InsightMaker software was used to construct and simulate the CLD. The model identified reinforcing loops showing how increased Mocaf production improves local food access, supports child nutrition, and enhances household income through Mocaf-based enterprises. Triangulated validation confirmed key causal pathways linking innovation, nutrition programs, and creative economic activity. Policy leverage points include supporting agroecological practices, promoting maternal education, and expanding market access. Findings suggest that Mocafproduction can simultaneously address public health and economic development goals. By integrating Mocaf into school feeding and micro-enterprise programs, communities can reduce stunting and boost income. The updated CLD also highlights potential risks such as market saturation and environmental degradation, underscoring the need for adaptive policies. This study contributes a validated systems model for rural development, offering practical insights for policymakers. It underscores that food system resilience requires coordinated strategies that address interconnected challenges across nutrition, agriculture, and livelihoods.Meningkatnya konsumsi tepung terigu di Indonesia telah mendorong inisiatif untuk mengurangi ketergantungan pada impor dengan mengoptimalkan sumber daya pangan lokal seperti singkong. Studi ini berfokus pada produksi mocaf (tepung singkong termodifikasi) di Desa Sindangsuka, Garut, di mana singkong—tanaman tahan kekeringan yang dapat dipanen sepanjang tahun—diolah menggunakan nira sebagai starter fermentasi. Tepung mocaf memiliki sifat fisikokimia yang lebih unggul dibandingkan dengan tepung terigu, sehingga menjadi alternatif yang layak untuk ketahanan pangan lokal. Penelitian ini mengintegrasikan ketahanan pangan, pengentasan stunting, dan ekonomi kreatif dengan menerapkan pendekatan berpikir sistem menggunakan Causal Loop Diagrams (CLD). Pendekatan ini mengidentifikasi variabel-variabel kunci dan keterkaitannya, sehingga memfasilitasi perumusan strategi efektif untuk meningkatkan pendapatan masyarakat dan mendukung ketahanan pangan lokal. Kebaruan penelitian ini terletak pada pendekatan sistemik inovatifnya, yang secara bersamaan menangani ketahanan pangan, pengurangan stunting, dan pengembangan ekonomi kreatif melalui produksi mocaf. Temuan menunjukkan bahwa produksi mocaf tidak hanya meningkatkan nutrisi bagi anak-anak yang mengalami stunting, tetapi juga merangsang pertumbuhan ekonomi lokal dengan memperkenalkan produk berbasis mocaf ke dalam ekonomi kreatif. Studi ini merekomendasikan untuk mendorong inovasi dalam produksi mocaf, memperluas jangkauan pasar, dan mendukung pertumbuhan pendapatan masyarakat untuk mencapai hasil yang berkelanjutan dalam ketahanan pangan dan pengembangan ekonomi

Thus, it can be concluded that if increasing the urban forest area in urban areas will have a positive impact on comfort, improve air quality, water, soil, and biodiversity, as well as enhance public health and welfare. Enhancing urban forests requires an approach that involves good urban planning, supportive policies, community participation, and the adoption of green technologies across the board, particularly in Makassar City. 
Urban Growth Dynamics in the New Capital of North Maluku: A Spatiotemporal Perspective on Land Cover Transformation in Sofifi
Full text linkThe transition of North Maluku Province\u27s capital city from Ternate to Sofifi in Halmahera Island is expected to spawn a new growth center. However, the development and expansion of urban areas in Sofifi reflect significant land cover transformation. This process is shaped by complex interactions influenced by the island’s geographical context and limited environmental carrying capacity. To ensure the sustainability of urban growth dynamics in Sofifi, this study aims (1) identify and analyze the spatiotemporal dynamics of land cover transformation from 1995 to 2020 in Sofifi and (2) analyze the growth pattern of urban expansion in Sofifi. This study employed multitemporal Landsat imageries within the 1995 to 2020 period with supervised classification using the CaRT classifier in Google Earth Engine and the NDBI maps to calculate the urban expansion rate and intensity index. The multitemporal analysis shows the rapid transformation of vegetation cover into built-up areas, especially in the 2010–2015 periods, which gradually developed from coastal areas towards inland following the development of road networks and government offices. The spatial expansion index shows the average urban growth in Sofifi from 1995 to 2020 is about 28.61%. This study reveals that the transformation of Sofifi land cover is shifting the vegetation cover to the built-up area by 967 hectares (27.61% of the Sofifi Area) from 1990 to 2020. Parallelly, urban expansion happens in stages. Moreover, this research advances the understanding of how land cover transformation and urban expansion happened in the island cities, particularly in the Indonesian context. 
Insect’s Bioconversion of Organic Waste: A Systematic Literature Review and Bibliometric Analysis
Full text linkFood waste, a type of solid waste is a significant environmental concern, particularly in developing nations. The utilization of insects as bioconversion agents is becoming more significant due to rapid population expansion and the rise in organic waste on a global scale. The research on waste bioconversion utilizing insects is now limited to a few bug species and lacks long-term strategy and sustainability considerations. This study conducted bibliometric analysis and a comprehensive literature evaluation on studies related to waste bioconversion processes utilizing insect bioconversion agents in publications from 2013 to 2023. A bibliometric analysis will offer an overview of research and collaboration trends in this sector, while a systematic literature review (SLR) will provide summaries on selected issues from relevant works. Studies on waste bioconversion using insects have primarily focused on key factors such as the type of organic waste, the rate of waste reduction achieved, the formulation of substrates tailored to insect nutritional needs, and the downstream utilization of insect biomass as feed or for energy production (biogas, biodiesel, and biomass fuel). Most of the existing research centers on the Black Soldier Fly (169 publications), which has demonstrated high efficiency in reducing organic waste. This concentration on BSF highlights a research gap and potential opportunities for investigating other insect species like crickets, mealworms that may offer different advantages in specific waste types or environmental conditions
Mitigasi Dampak Lingkungan Melalui Biofiltrasi Merkuri (Hg) dari Limbah Tambang Emas Menggunakan Parupuk (Phragmites karka): Pendekatan Fitoremediasi Berbasis Tanaman Lokal dalam Pengolahan Air Limbah Tambang
No full textMercury pollution from gold mining wastewater remains a major environmental concern due to its persistence and toxicity, driving interest in sustainable, low cost phytoremediation using native wetland plants. This research examines the phytoremediation capacity of Phragmites karka (locally referred to as Parupuk) in mitigating mercury contamination, with a particular focus on mercury (Hg), from wastewater derived from abandoned gold mining sites. A quasi experimental approach was implemented with exposure periods of 0, 3, 6, and 9 days. Approximately 1.5 kg (8 clumps) of live biomass was placed into custom designed 100 L glass bioreactors equipped with continuous water circulation. Key water quality indicators including pH, Chemical Oxygen Demand (COD),Biological Oxygen Demand (BOD), and Hg concentrations were systematically evaluated. Results indicated an increase in pH from 5.8 to 6.0, a 23.17% reduction in BOD (8.9 mg/L), and an 16.67% decline in COD (20 mg/L). The residual Hg concentration reached 0.0044 mg/L, which is below the permissible limit of 0.005 mg/L set by the Indonesian Water Quality Standard (Regulation No. 5/2022). These outcomes demonstrate the dual role of Phragmites karka as both a biological remediator and a fibrous filtration medium for water quality enhancement. Although the system is capable of meeting regulatory thresholds, further research is needed to clarify how Hgsequestration works and to determine the significant and specific contributions to plant structural attributes. This work establishes a scientific basis for further studies aimed at optimizing and scaling phytoremediation technologies for sustainable application in post-mining environments.Penelitian ini bertujuan untuk menilai laju penurunan logam berat dalam air dari lokasi bekas tambang emas dengan menggunakan tanaman Parupuk (Phragmites karka).

Visitor Preferences for Restorative Landscape Elements in Bogor Urban Parks: A Visitor-Employed Photography Approach
Full text linkHuman health and well-being are affected by the quality of the environment in which an individual lives. Urban spaces must provide restorative experiences to support public mental health. This study aimed to identify visitor preferences for exciting views and stress-relieving features in urban parks. Using visitor-employed photography to capture direct experiences, the study analyzed geotagged photos to identify landscape views, classified restorative landscape elements, and evaluated their effect on urban park visitors. This research employed spatial analysis of photo distribution using QGIS, photo content analysis using Google Cloud Vision API, and assessment of restorative effect through the Perceived Restorativeness Scale (PRS). The photo-taking hotspots were shaded areas with seating, featuring greenery, sculptures, activities, and landmarks. The results showed 2–3 hotspots with the highest photo density in the three parks. The Cloud Vision API classification results identified that the elements of a restorative landscape can be softscape, hardscape, and other factors. The results of the PRS questionnaire test showed that the three parks had a restorative effect on visitors (< 0.05), Sempur Park had the highest fascination (55.13) and compatibility (55.57) effects, and Heulang Park had the highest coherence effect (56.85) than other parks. These findings emphasize the importance of incorporating shaded seating, greenery, and engaging features into urban park designs to enhance visitor health and well-being. 
Developing a Forestry Business Model Through the Business Model Canvas: A Case Study in Gerlang Village, Batang Regency, Central Java
No full textAt the local level, social forestry is a key strategy for implementing sustainable forest management that aims to reduce poverty, empower local communities, and improve forest conditions. Granting forest area management permits to local communities requires good business development planning. This study used the business model canvas framework to develop a new business model. The result showed that a new business model was developed by considering the benefits of vegetables, arabica coffee, and tree carbon storage as the value propositions. The customer segments were housewives, restaurant owners, coffee shop owners, and CO2-emitting companies. The products were distributed through trader networks and voluntary carbon market mechanisms. Farmers established direct relationships with trader networks. Revenue streams were derived from the sales of fresh potatoes, carrots, leeks, chilies, coffee beans, and carbon credits. This business model required an area, irrigation equipment, farming equipment, seeds, fertilizers, laborers, and tree biomass measuring tools. Key activities included farming, measurement, and calculation of carbon storage estimates. The partners in this business model were community organisations and local government agencies. The cost structures were investment, operational farming, and costs associated with measuring and calculating carbon storage
The Role of Stakeholders in Managing Social Forestry Business Development in FMU South Bandung, Indonesia
Full text linkSocial forestry symbolizes a sustainable forest management strategy, where local communities are important in strengthening socio-economic aspects, namely welfare and environmental sustainability. Increasing community welfare depends on collective efforts of social forestry, regional regulations, institutional structures, and cooperative with various stakeholders. Subsequent analysis employed the stakeholder analysis model, which scrutinizes stakeholders\u27 roles in natural resource management. The examination compares roles outlined in policy with stakeholders\u27 actual engagement. Consequently, the research provides insights into how stakeholders contribute to social forestry business development based on two critical factors: interest and influence. Results indicate that stakeholders\u27 roles and contributions are substantially influenced by policy, especially concerning their interests and impact on community business ventures in social forestry. Stakeholder analysis reveals that governmental bodies, as mandated by policy, predominantly occupy quadrant II, tasked with aiding community groups in advancing social forestry businesses. However, quadrant I also encompasses governmental entities, albeit with limited involvement in community group activities. QuadrantsIII and IV underscore the diverse roles stakeholders assume within their respective domains, reflecting their interests and influence on business development initiatives to empower the community and improve the livelihood. This research aims to formulate tactics to enhance stakeholder involvement in implementing nation policies for fostering social forestry enterprises within the FMU South Bandung. The tactics need support of each party, especially the social forestry regulation in developing the business and capacity agency in measurement of accessible market, business plan, valuable product and good forest institutions
