Abstract

The agroforestry system is a solution offered so that the forest area does not decrease due to forest destruction and the environment is able to perform its function, namely as a carbon storage. This study was aimed to determine the potential for carbon stored in coffee stands and abiotic factors in coffee stands on agroforestry land. Samples by purposive sampling stand samples of Coffeaarabica, Coffea canephora, and Coffea liberica as many as 20 trees with a total sample of 60 stands. the abiotic factor was measured at three representative points. Data obtained in the form of dbh (±1,3 m), type of coffee, plant age, wood dencity, abiotic factor data, biomass, and carbon. Data analysis included tree biomass data with the allometric formula Ketterings dry weight = 0.11 ρ D2.62 (2001) and  allometric formula Arifin dry weight = 0.281 D2.0635 (2001). Data analysis included carbon biomass = dry weight x 0.47. The results showed that the largest carbon storage was in Coffea liberica, then Coffea canephora and the smallest carbon storage was in Coffeaarabica. abotic factors in coffee agroforestry show soil moisture 18.3%, air humidity 60 - 75%, soil pH  7.3, soil temperature  21 ° C, air temperature 21 - 25 ° C, light intensity  877 lux, and altitude ranges from 906 - 934 m asl.Keywords: allometric, coffee, agroforestry, abiotic factors, carbonABSTRAKSistem agroforestri merupakan solusi yang ditawarkan agar luas hutan tidak semakin berkurang akibat kerusakan hutan dan lingkungan mampu melakukan fungsinya yakni sebagai penyimpan karbon.

Abstract

Increasing coffee farmer capacity to produce good coffee bean standar was important. The objective of community service activities were to (1) increase community knowledge about coffee trade prospects and the need for quality coffee, (2) increase community understanding of good coffee farming practices to produce quality coffee beans and (3) increase community understanding of how to recognize coffee bean quality based on basic organoleptic tests. Increasing farmers' knowledge and capacity in coffee production can be done by conducting hands-on training involving strategic partners. Partners involved in this activity include coffee farmers around KPH northern Banyuwangi, Perhutani, local community organizations (MWC NU, Karang Taruna) and coffee observers and activists in Banyuwangi Regency. The activities succeeded in increasing community knowledge about coffee trade prospects and quality coffee. The farmers have understood the market and provide quality coffee beans to meet market expectations. This activity improved the community's understanding of good coffee farming practices to produce quality coffee beans. Good cultivation is crucial to coffee's competitiveness and sustainability. This activity succeeded in improving the community's understanding of how to recognize coffee bean quality. The community gained basic knowledge related to basic organoleptic testing, but these skills need to be improved. Participants have been able to separate beans that are defective, broken, infested with fleas/insects, cracked, contain epidermis, and other characteristics that are not suitable as good quality coffee for processing. Overall the activity received good appreciation from the community, it is hoped that in the future assistance will continue.

Abstract

This study aims to analyze the strategy of strengthening beef cattle farming through an integrated agribusiness subsystem approach at the Sebatur Tunggal Farmer Group in Muara Badak District, Kutai Kartanegara Regency. The background of this study is based on the importance of developing an integrated agribusiness system to increase the productivity and competitiveness of smallholder livestock farming, especially in the face of challenges such as feed availability, market access, and institutional and technological support. This study uses a qualitative descriptive method with a case study approach, where data is collected through observation, in-depth interviews with members of farmer groups and related parties, and documentation studies. The results of the study indicate that each agribusiness subsystem—starting from the input subsystem (upstream), cultivation subsystem (on-farm), processing and marketing subsystem (downstream), to supporting subsystems such as institutions, capital, and technology—is still running partially and has not been optimally integrated. The main problems identified include limited access to quality feed, low application of efficient cultivation technology, limitations in processing livestock products, and weak marketing and partnership networks. In addition, the institutional capacity of farmer groups to manage businesses collectively still needs to be strengthened. The conclusion of this study states that the strategy for strengthening beef cattle farming businesses needs to be focused on developing an integrated agribusiness system with support from training, extension, access to inputs and markets, and cross-sector collaboration. The main recommendation is the need for policy interventions that encourage synergy between subsystems and empower farmers through a participatory and sustainable approach to create a resilient and competitive community farm.

Abstract

Kedang Murung Village has strategic potential to develop nature and culture-based tourism, with Tanjung Sarai Lake as the main attraction. The uniqueness of nature, local wisdom, and rich traditions are essential to forming an authentic tourist destination identity. Active community involvement supported by high social solidarity shows the community's readiness to support sustainable tourism initiatives. As a result, there is a real contribution to increasing community income and local economic growth. However, tourism development faces several obstacles, such as limited supporting infrastructure, minimal budget, and low managerial capacity of the community in managing tourism businesses. This study recommends strengthening synergy between the village government, the private sector, and local communities through a collaborative approach to planning and implementing tourism programs. Information technology, especially digital media, is essential to increase promotion effectiveness and market reach. In addition, training and mentoring for the community in managing small and medium enterprises (MSMEs) need to be intensified to increase entrepreneurial capacity and strengthen the competitiveness of the village as a tourist destination. These efforts are expected to enhance the local economy and support environmental conservation and sustainable cultural preservation.

Abstract

The roasting process is one of the keys in the coffee production stage. Roasting affects the quality of coffee in terms of organoleptic characteristics.This study aims to analyze the chemical content of liberica coffee. The research was carried out at the Kalipuro Research Institute (Kembang Galengan) using two types of roasting methods, namely conventional and modern (machine-roasted). Testing of liberica coffee samples by analyzing water content, ash content, acidity levels (pH), and caffeine. The results showed that modern coffee roasting produces a water content of 4%, ash content of 5.1%, acidity (pH) of 4.7, and caffeine content of 0.47%. Meanwhile, conventional roasting produces a water content of 2.5%, ash content of 4.9%, acidity (pH) of 4.7%, and caffeine content of 0.28%. Based on these results, it can be concluded that all categories of liberica coffee processed conventionally and modernly (machine-roasted) at the Kalipuro Research and Development Center qualify for SNI standards.

Abstract

Augmented Reality and Virtual Reality are increasingly used in biology and life sciences education. In the past decade, 34 Scopus-indexed studies (2015–2025) have examined their effects on conceptual understanding and scientific literacy. This study demonstrates that AR/VR meaningfully enhances biology learning by making lessons more immersive and interactive, thereby improving students' understanding of complex biological concepts and supporting higher-order thinking. AR helps visualize biological structures and processes, while VR enables exploration of human anatomy and virtual ecosystems. Despite these benefits, further long-term and comprehensive research is needed to better integrate AR/VR with other teaching methods. The study provides an overview of AR/VR use in Indonesian biology education, highlighting key research gaps, including the need for more evidence on long-term effects and practical classroom challenges. Together, these findings offer guidance for designing future technology-based biology instruction.

Abstract

Karst springs, such as the Jalasundra-Mbrumbun springs in East Java, Indonesia, have considerable potential to integrate natural conservation and tourism development. However, flora inventories and studies examining the relationship between plant diversity and tourism remain limited in karst areas. This study aims to identify plant species in the spring area and to explore tourism-related aspects associated with the site. Plant species were documented through field observations, while plant nomenclature and distribution status were determined using the Royal Botanic Gardens’ Plants of the World Online database. Tourism data were obtained through semi-structured interviews using purposive sampling involving five respondents, as well as direct observation of the four key tourism components (4A). A total of eighteen plant species were identified in the spring area, the majority of which are native species (12 species). Several plant species found in the area are considered sacred, including Ficus kurzii, Ficus benjamina, and Pimelodendron sp. In addition, the presence of an invasive species, Muntingia calabura, poses a significant threat to ecosystem balance. Therefore, preserving native species and controlling invasive species are essential for maintaining spring ecosystem sustainability. Furthermore, attention to the 4A tourism components, alongside native species conservation, represents a key element in strengthening the relationship between conservation and tourism.
