Older people risk poor nutritional status during natural disasters due to low intakes of energy, carbohydrates, protein, and fat. A food bar is a form of emergency food product that contains carbohydrate and protein, and is practical for disaster situations. The study aimed to investigate the effect of a broccoli-soybean-mangrove food bar on older people’s weight following natural disasters. A quasi-experimental pre-post intervention study was designed using 33 subjects at the treatment group of various nutritional status types of older people during two weeks with balanced nutrition education over two weeks. Bivariate analysis with a paired t-test used to test whether weight, macronutrient intakes, and balanced nutrition knowledge were significantly different before and after the study. The study showed broccoli-soybean-mangrove food bar consumption resulted in a significantly increased weight of 0.2 kg, energy (291.9 kcal), protein (6.1 g), carbohydrate (31.1 g), dan fat (15.6 g) intakes. Balanced nutrition education of older people could also substantially increase knowledge of older people regarding nutrition (11.8 points). The proportion of malnourished subjects who gained weight was more remarkable than normal subjects in the first and second weeks of the intervention. However, the proportion of normal nutritional status subjects having increased macronutrients intakes was higher than the malnourished subjects. These findings recommend broccoli-soybean-mangrove food bar consumption to significantly improve weight and macronutrients intakes in older people following a natural disaster. It is necessary to make the broccoli-soybean-mangrove food bar more available, accessible, and affordable to all people in emergencies, mainly for older people.

This study addresses the persistent environmental challenges associated with coal mining in tropical and subtropical regions, where complex microclimates and ecological variability hinder effective reclamation. Despite the increasing global coal demand, comparative cross-country insights remain limited. This research fills the gap by evaluating the best practices. This study employs a qualitative methodology with a comparative case study design, uses systematic literature review to evaluate ecology based reclamation policies and implementation practices. Data were sourced from peer-reviewed journals from Scopus and the Web of Science database and institutional reports, and analyzed using McHarg’s landscape ecology theory to evaluate reclamation policies, ecological challenges, and implementation practices. The results reveal that while all four tropical coal-producing countries possess clear regulatory frameworks for reclamation, their effectiveness varies due to ecological, climatic, and enforcement disparities. Australia demonstrates the most successful model, integrating strict policies with advanced technology and sustainable financing. Conversely, Colombia, Indonesia, and South Africa face challenges in enforcement and consistency. Thematic analysis from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), shows that research is dominated by ecological and biodiversity aspects (44 articles), followed by reclamation technologies (22), economic-social factors (8), and regulatory studies (3). Aligning with McHarg’s landscape ecology theory, the study finds that successful reclamation hinges on site-specific ecological strategies, that are responsive to microclimates and landscape typologies. Technologies such as overburden non-acid forming (OB-NAF) encapsulation and electrodialysis reflect the ecosystem-based approach. However, future research must include empirical validation and community participation to strengthen long-term reclamation success and ecological resilience.

Sampah masih menjadi salah satu masalah di Indonesia. Sejak tahun 2017, volume sampah yang terangkut di Indonesia masih belum memenuhi target, termasuk di Desa Tubanan, Kecamatan Kembangan, Kabupaten Jepara, Jawa Tengah. 30-63% sampah yang dihasilkan adalah sampah organik. Pengelolaan sampah dengan biokonversi larva Black Soldier Fly dapat menjadi solusi untuk permasalahan sampah di Indonesia. Karena manfaatnya dapat mereduksi 80% sampah dan dapat membentuk ekonomi sirkular untuk masyarakat. Keuntungan ekonomi dapat didapatkan dari hasil penjualan produk ataupun pengurangan biaya pengelolaan sampah. Pengolahan sampah dengan biokonversi larva Black Soldier Fly tidak berdampak padak kesehatan masyarakat dan tidak menimbulkan bau. Sehingga, pengolahan sampah dengan biokonversi larva Black Soldier Fly dapat menjadi salah satu alternatif dalam menyelesaikan permasalahan sampah di Indonesia. Tujuan dari penelitian ini adalah memformulasikan model pengelolaan sampah organik dengan biokonversi larva Black Soldier Fly berbasis pemberdayaan masyarakat dalam aspek lingkungan, sosial, ekonomi, dengan perlakuan formula nutrisi pakan yang tepat. Penelitian ini dilakukan dengan menganalisis keuntungan yang didapatkan di antara 3 jenis sampah sebagai formula nutrisi pakan (sampah dari masyarakat, sampah sisa pemotongan ikan, dan sampah campuran dari keduanya). Analisis menggunakan sistem dinamik dan analisis statistik menggunakan SPSS. Berdasarkan simulasi model yang telah dilakukan, nilai ekonomi tertinggi dihasilkan oleh intervensi penggunaan sampah campuran antara sampah dari masyarakat yang dapat terolah 100% dan sisa pemotongan ikan. Selain itu sampah campuran juga dapat menghasilkan total biomassa product tertinggi dibandingkan jenis sampah lainnya. Maka, dapat disimpulkan bahwa model pengelolaan sampah organik dengan biokonversi larva Black Soldier Fly berbasis pemberdayaan masyarakat menggunakan sampah campuran (sampah dari masyarakat yang dapat terolah 100% dan sisa pemotongan ikan) dapat dipilih sebagai metode pengelolaan sampah yang tepat di Desa Tubanan, Kecamatan Kembangan, Kabupaten Jepara, Jawa Tengah.

Weeds become the major thread in the agriculture system especially for rice crops. Individual density per 0,1 m could decrease 57% of dryland rice production. We aimed to determine the strategy for manage the rice weeds in eco-friendly dryland as the effort to conserve the biodiversity. The methodology used is mixed method with observation and in-depth interview. The research was conducted in July – Oktober 2018, Sudimoro district, Pacitan Regency, East Java. The weeds that dominantly by important value index is Alternanthera sessilis (L.) R.Br. Ex DC (4,41) and Synedrella nodiflora (L.) J. Gaertner (2,84). The farmer tends to manage the weed chemically; even 100% respondent admitted the use of 42.86% chemical and mechanical to manage the weeds, meanwhile the rest 57.14% used only chemical (herbicide). To the farmers, the use of herbicide is believed as the most effective solution, it takes only few times, less energy, and more affordable than mechanic control. However, 42.86% of respondents indicated that the weed turned more resistant because even it was sprayed by herbicide, the weeds kept growing up. In the other side, the existence of pollinator insect and odonata were no longer as much as in the past time, moreover, somehow, odonata was totally disappeared. This reflection shows that the quality of ecosystem was disturbed by the use of herbicide. The management using the prior ecological principles is the best solution to conserve the ecosystem. This one can be gained through combining mechanical and biologycal management.

Poverty is an issue that continues to be discussed in the world. Poverty is multi-dimensional and requires the participation of all parties to resolve. Poverty has implications for the environmental damage caused by access to natural resources are made public. This study aims to apply the principles of eco-habitat (integrate economically and ecologically) in rural areas to increase incomes while preserving the environment. The study was conducted with a mixed method through observation, interviews, and literature review. That 68 percent of respondents never perform actions that lead to environmental destruction; 72 percent know that his actions have consequences for the extinction of organisms. Meanwhile, 57 percent say it is because there was another choice for needs. Furthermore, 100 percent of respondents agree with the strategy of environmental conservation by utilizing the types of organisms which has an economic value. Ecological suitability-based land management provides the most optimal production value. Management of pattern and type of land it gives the production value is very small, because of the high cost of planting, pest attacks, and controls that are environmental unfriendly. This should be targeted at land management based ecological suitability to provide economic and ecological values are high. This principle has many benefits including CO2 sequestration, absorb and store water, provide habitat for organisms, and provide economic value for society. Finally, the land use pattern encourages a sense of ownership of natural resource and environmental ecosystems, that they have the willingness to manage and preserve it.Keywords: agriculture, ecosystems, environmental degradation, income, povertyAbstrakKemiskinan menjadi isu yang terus diperbincangkan di seluruh belahan dunia, yang harus diselesaikan pada tahun 2030. Kemiskinan bersifat multi dimensi dan membutuhkan partisipasi dari semua pihak untuk menyelesaikannya. Kemiskinan berimplikasi pada terjadinya kerusakan lingkungan akibat akses sumber daya alam yang dilakukan masyarakat. Penelitian ini bertujuan untuk menganalisis penerapan prinsip eko-habitat (mengintegrasikan aspek ekonomi dan ekologi) di kawasan pedesaan untuk meningkatkan pendapatan masyarakat sekaligus melestarikan lingkungan. Penelitian dilakukan dengan mixed method melalui observasi, wawancara, dan kajian pustaka. Berdasarkan hasil penelitian diketahui bahwa 68 persen responden pernah melakukan tindakan yang mengarah pada perusakan lingkungan; 72 persen mengetahui bahwa tindakannya memiliki konsekuensi terhadap kepunahan organisme. Sementara 57 persen menyatakan hal tersebut dilakukan karena tidak ada pilihan lain untuk memenuhi kebutuhan hidup. Di sisi lain, 100 persen responden setuju dengan strategi pelestarian lingkungan dengan memanfaatkan jenis-jenis organisme yang bernilai ekonomi. Pengelolaan lahan berbasis kesesuaian ekologis memberikan nilai produksi yang paling optimal. Pola pengelolaan dan jenis lahan yang justru memberikan nilai produksi yang sangat kecil, karena tingginya biaya tanam, serangan organisme pengganggu tanaman, dan pengendalian yang tidak ramah lingkungan. Perlu diutamakan pengelolaan lahan berbasis kesesuaian ekologis untuk memberikan nilai ekonomi dan ekologi yang tinggi. Tentunya prinsip ini memiliki banyak manfaat di antaranya menyerap CO2, menyerap, dan menyimpan air, menyediakan habitat organisme, dan memberikan nilai ekonomi bagi masyarakat. Pada akhirnya dengan pola pemanfaatan lahan tersebut masyarakat memiliki rasa kepemilikan terhadap ekosistem alam dan lingkungan, sehingga mereka memiliki kemauan untuk menjaga dan melestarikannya.Kata kunci: ekosistem, kemiskinan, kerusakan lingkungan, pendapatan, pertanian

This study is associated with the increased pressure on hill resources due to land conversion that causes environmental degradation and leads to environmental unsustainability. The evenly spread hill known as Bukit Sepuluh Ribu, is a source of community life. The hill formed by the eruption of a volcano, has a land cover, namely close to forest vegetation. The study location is in Bukit Sepuluh Ribu area that has ecological, hydrological, geological and aesthetic environmental function. The concept of community empowerment through Agro-ecosystem can be a solution, thus the utilization of the hill is economically profitable and environmentally sustainable. There are land use unsuitability referring to the existing spatial plan (682.9 Ha), namely high densely settlement area (264.67 Ha), other agriculture (359.21 Ha) and mining areas (58.51 Ha), Through the concept of appropriate community empowerment in accordance with the rules and typology of hill areas can provide the potential benefits of ecosystems and produce products of economic value without damaging them. The concept of empowerment through dryland agro-ecosystem by combining forest-based agriculture activities is one of the solutions to the problem of land management.
