Implementasi prinsip pemilahan sampah reduce, reuse, dan recycle melalui bank sampah belum banyak berkembang di masyarakat. Inisiasi bank sampah masih dihadapkan dengan berbagai kendala seperti literasi ekologi tentang sampah yang masih kurang serta minimnya tenaga penggerak bank sampah itu sendiri. Kegiatan pengabdian masyarakat di Dusun Kepuh ini bertujuan untuk menguatkan literasi ekologi permasalahan sampah serta menginisiasi bank sampah tingkat desa. Metode pendekatan yang digunakan adalah partisipatory rural appraisal (PRA) dengan masyarakat mitra kelompok PKK. Dalam rangka meningkatkan pengetahuan dan sikap mitra terkait literasi sampah digunakan pendekatan kelompok dengan teknik penyuluhan. Materi penyuluhan yang diberikan meliputi: (1) Edukasi masalah sampah, (2) Pemetaan perilaku rumah tangga terhadap sampah, serta (3) Urgensi keberadaan bank sampah. Sedangkan untuk meningkatkan keterampilan pengelolaan bank sampah dilakukan dengan teknik praktek, pendampingan, operasional bank sampah, studi banding, serta monitoring dan evaluasi terhadap keberjalanan program bank sampah. Berdasarkan program yang telah terlaksana, diperoleh hasil yaitu; (1) Berdasarkan peta pemanfaatan sampah, sebagian kecil rumah tangga PKK sudah berupaya memanfaatkan sampah jenis tertentu. (2) Inisiasi bank sampah diharapkan mampu menguatkan perilaku rumah tangga PKK dalam memanfaatkan sampah, hal ini terlihat dari adanya peningkatan partisipasi anggota PKK dalam kegiatan operasional bank sampah, serta para pengurus telah memiliki ketrampilan dalam menjalankan bank sampah.

Temanggung robusta coffee is a potential plantation commodity in Central Java that has existed since the colonial era. Its development has gone through various policies, both from the top down and bottom up. This research was based on empirical facts and phenomena on the development of Temanggung robusta coffee. The researchers conducted participatory observations, discussions, and in-depth interviews with 15 informants. Data analysis was done through a socio-historical and descriptive approach to accurately understand the evidence, history, and correlations between phenomena. This study’s results prove that the transformation stage of Temanggung robusta coffee began in the era of forced cultivation of “Koffie Stelsel” through patron-client relationships. This development continues to experience socio-cultural shifts with a variety of different policies. Currently, three sectors are the main players in Temanggung robusta coffee (government, large private plantations, and the community). The factors causing the success of Temanggung coffee not to be achieved are 1) the large area of land but low productivity; 2) the process of randomly picking coffee; 3) policies that are not yet optimal; 4) minimal market share; 5) the capacity of extension agents in the coffee commodity is still low; 6) lack of cooperation between stakeholders.

Desa Kebakalan, Kecamatan Karanggayam, Kabupaten Kebumen merupakan salah satu desa yang menerima program Pengelolaan Hutan Bersama Masyarakat dari Perum Perhutani Jawa Tengah. Melalui program tersebut, masyarakat Desa Kebakalan menerima bantuan bibit kopi yang diberikan kepada Lembaga Masyarakat Hutan Desa (LMDH) Wana Asri. Akan tetapi, petani kopi di Desa Kebakalan masih memiliki pengetahuan yang rendah mengenai cara budidaya kopi dan pengolahan pasca-panen. Penelitian ini bertujuan untuk memberikan literatur terkait peran penting knowledge sharing kelompok LMDH Wana Asri dalam meningkatkan pengetahuan tentang budidaya kopi baik pada peningkatan kualitas tanaman, hasil, dan keberlanjutan. Metode penelitian yaitu sosial kualitatif dengan pendekatan studi kasus. Wawancara mendalam dilakukan kepada 7 informan petani kopi yang dipilih secara purposive. Selain itu, dilakukan observasi dan kajian data sekunder. Kegiatan knowledge sharing dilakukan melalui diskusi (offline dan online) dan praktik langsung.Selain praktik budidaya, petani kopi juga melakukan praktik pengolahan pasca-panen yang meliputi praktik sortasi cherry kopi, pemecahan kulit menggunakan pulper, pengeringan, hingga roasting menggunakan mesin sangrai (roaster). Adapun peran penting dari knowledge sharing yaitu: 1) mendorong dan membuka wawasan petani; 2) memfasilitasi pengembangan kompetensi petani dalam kemandirian dan berinovasi; 3) pengaruh positif dalam meningkatkan kepercayaan diri para petani; 4) memunculkan jaringan kemitraan dan spirit dalam pengembangan komoditas kopi yang baik dan berkelanjutan. Kebakalan Village, Karanggayam District, Kebumen Regency is one of the villages that received the Community Forest Management program from Perum Perhutani Central Java. Through this program, the people of Kebakalan Village received coffee seed assistance provided by the Wana Asri Village Forest Community Institute (LMDH). However, coffee farmers in Kebakalan Village still need more knowledge about cultivating coffee and post-harvest processing. This study aims to provide literature on the vital role of knowledge sharing of the LMDH Wana Asri group in increasing knowledge about coffee cultivation in improving crop quality, yield, and sustainability. The research method is social qualitative with a case study approach. In-depth interviews were conducted with seven purposively selected coffee farmer informants. In addition, observations and secondary data studies were conducted. Knowledge-sharing activities are carried out through discussions (offline and online) and direct practice. In addition to cultivation practices, coffee farmers also carry out post-harvest processing practices, including coffee cherry sorting practices, skin splitting using pulpers, drying, and roasting using roaster machines. The important roles of knowledge sharing are: (1) Encouraging and opening farmers' insights; (2) Facilitating the development of farmers' competencies in self-reliance and innovation; (3) Positive influence in increasing the confidence of farmers; (4) Establishing a network of partnerships and spirits in the development of excellent and sustainable coffee commodities.

The investigation of alternative raw materials for gelatine production from fishery industry by-products has gained attention due to the increasing demand for gelatine and the importance for sustainable practices. This study aims to determine the optimal hydrochloric acid (HCl) concentration for mineral removal during pre-treatment, assess hydroxyproline content at various processing stages and characterise the resultant gelatine. The methodology involved pre-treatment of the materials with 0.1 M sodium hydroxide (NaOH) to remove non-collagen proteins, followed by mineral extraction using varying HCl concentrations (0.25, 0.5, 0.75 and 1 M). The process included swelling in 0.2% citric acid for 12 h and gelatine extraction at 65°C for 7 h. The results indicated that 0.25 M HCl was most effective for mineral removal. The hydroxyproline analysis showed an insignificant increase (0.088 mg/mL–0.103 mg/mL) from the pre-treatment stage to the final gelatine product. The physicochemical properties of the liquid gelatine, including yield (6.5 ± 0.39%), pH (6.55 ± 0.11), and gel bloom strength (174 ± 8.54 blooms) conformed to Gelatin Manufacturers Institute of America (GMIA). Functional groups confirmed the presence of gelatine-specific, such as amides A, B, I, II and III. The molecular profile is comparable to commercial gelatine, with ?1 chains at 130 kDa, ?2 chains at 115 kDa, and ? chains at 235 kDa. The gelatine derived from the scaly skin of purple-spotted bigeye exhibits promising attributes, aligning with commercial standards and highlights the potential of fishery by-products as a sustainable and halal source of gelatine.

The Climate Village Program (ProKlim) aims to strengthen community participation in local climate mitigation and adaptation. Although several areas in Surakarta have reached the Main Class category, sustaining community motivation remains a challenge. This study analyzes the sustainability of ProKlim by examining social, economic, and environmental factors influencing long-term engagement. Using a qualitative case study approach, data were collected through in-depth interviews, FGDs, observations, and documentation. The findings show that strong social capital and local leadership support sustainability, while fluctuating participation, dependence on external incentives, and limited cadre regeneration hinder continuity. Economic activities exist but remain small-scale. The results imply that continuous mentoring, strengthened community-based economic initiatives, and structured monitoring are essential to ensure sustained ProKlim implementation beyond assessment cycle. The result imply that continuous mentoring, strengthened community-base economic initiatives, and structured monitoring to maintain consistent ProKlim implementation beyond competition cycles. Strengthening these aspects is essential for ensuring the ling-term sustainability of Main Class ProKlim as a community-driven climate resilience initiative.

Forest resources play an essential role in supporting the livelihoods of forest farming households. Households in this area depend heavily on forest-related activities as a source of income and livelihood. However, forest farming households are often faced with various challenges and uncertainties due to climate change, market fluctuations, limited access to land ownership, lack of infrastructure and technological support, and developments in socio-economic conditions that change the values and structure of people's lives. This study is a preliminary survey as an initial process of collecting information and data before carrying out the primary research. This preliminary survey aims to gain an initial understanding of the diversity of forest farmer household livelihoods. Data was collected through a rapid study of 30 households in Gandu Village. Then, data was identified according to information needs and planning the next steps. The results of this study show that forest farming households in Gandu Village diversify their livelihoods in both the agricultural and non-agricultural sectors. The diversity value in the non-agricultural sector shows an average figure of 2.1, which means that each household does not only depend on one source of income. However, they will diversify the number of livelihoods in the amount of 2.1 to meet their household's living needs. The findings of this preliminary survey can become initial data and contribute to further research.
