This research sought to pioneer advancements in the circular economy by investigating the feasibility of utilizing used coffee grounds in creating eco-friendly plantable pencils. This research compared coffee pencils to wood and synthetic pencils. It also provided a cost-benefit analysis comparing the manufacture of coffee pencils and ordinary pencils. The research examined market potential, consumer acceptability, and possible barriers to commercialization and broad adoption of eco-friendly plantable pencils made from recycled coffee grounds. The methodology included a coffee pencil marketing strategy. The results show that plantable pencils made from used coffee grounds are comparable in mechanical and physical properties to traditional pencils. Furthermore, the cost-benefit analysis indicates that coffee pencil production is more cost-effective and environmentally friendly than its traditional counterparts. Consumer acceptance shows rising interest in eco-friendly plantable pencils, despite identified challenges and impediments such as a dearth of awareness and composting infrastructure. The study successfully demonstrates the potential for using used coffee grounds in the creation of eco-friendly plantable pencils. Additionally, it provides valuable insights into the commercialization and broad adoption of this innovative product. The strategic development plan suggested involves undertaking marketing and educational campaigns, investing in research and development, and fostering partnerships with stakeholders. This study sets forth the practical considerations required for the successful commercialization and acceptance of plantable coffee pencils, further promoting a circular economy.

The purpose of this research was to analyze the livelihood of farmers on fire-prone peatlands and their efforts to maintain their sustainable livelihoods. The study took place in Banjarbaru, Indonesia, a fire-prone peatland area. Our 251 samples were farmers cultivating the peatland. The variables measured in this study were livelihood assets, including human assets, social assets, natural assets, physical assets, and financial assets. We employed classification and principal component analysis. The findings revealed that physical and natural assets played the most significant roles in ensuring the sustainability of farmers’ livelihoods in the fire-prone peatland. Human assets also played an important role because the farmers have been cultivating peatlands for a long time, giving them the skills and knowledge for sustainable and zero-burning peatland management. Peatlands managed by farmers have a low fire potential because farmers protect their land from burning. Social and financial assets did not play significant roles because the farmers did not take advantage of the existing cooperatives and farmer groups. Increasing the role of cooperatives and farmer groups would improve people's livelihoods by increasing the contribution of social and financial assets. Sustainable peatland cultivation as a productive space has proven beneficial for preventing fires on peatlands (ecology) and livelihoods (economy).

Increasing productivity is a challenge for small farmers in managing their farms. The objectives of this study were to analyze the technical efficiency of potato farming using local knowledge of traditional agriculture and to analyze the variables that contribute to the technical inefficiency of potato farming in the Arfak Mountains. This study was conducted in three districts of the Arfak Mountains Regency of West Papua Province: Anggi, Sururey, and Hingk. This study used cross-sectional data obtained from structured interviews with 140 farmers. The determinants and efficiency levels were estimated using stochastic frontier analysis. The findings of this study indicate that farmers who implement traditional farming systems with local knowledge have an average technical efficiency of 52%, equivalent to the average technical efficiency value of potatoes in other developing countries without local knowledge of 40–70 percent. The variables of extension frequency, total household income, degree of output commercialization, distance between the farmer’s house and the farm location, and fallow length are the determining factors for farmers' technical efficiency. The implication is that traditional farmers can improve their technical efficiency through technological improvements, the use of appropriate inputs, infrastructure improvements, intensive counseling, and assistance in correctly managing their farms.

This study explores the influence of varying biochar rates and planting distances on the growth and yield of inbred rice. The randomized complete block design (RCBD) implemented a two-factorial design with four biochar rates (none, 25 MT/ha, 20 MT/ha, 15 MT/ha) and three planting distances (20 cm x 20 cm, 20 cm x 25 cm, 20 cm x 30 cm). The 20 MT/ha biochar application (A3) manifested the highest mean outcomes for plant height, productive tillers, panicle length, weight of 1,000 grains, filled grains percentage, and estimated yield. However, the highest mean biomass yield was observed with 25 MT/ha biochar (A2). The 20 cm x 20 cm planting distance (B1) displayed the highest mean panicle length, while B2 (20 cm x 25 cm) produced the highest filled grains percentage and lowest unfilled grains percentage. B3 (20 cm x 30 cm) showed the highest mean values for plant height, productive tillers, biomass yield, estimated yield, and weight of 1,000 grains. The highest yield and return on investment (ROI) were seen in Treatment 6 (25 MT/ha of biochar at a 20 cm x 30 cm planting distance), revealing that increased biochar application results in higher yield at a 20 cm x 30 cm planting distance. The findings suggest that biochar application can augment the growth and yield of inbred rice across diverse planting distances.
本研究探讨了不同生物炭用量和种植距离对自交系水稻生长和产量的影响。随机完全区组设计(RCBD)采用两因子设计，采用四种生物炭配比(无、25 MT/ha、20 MT/ha、15 MT/ha)和三种种植距离(20 cm × 20 cm、20 cm × 25 cm、20 cm × 30 cm)。施用20 MT/ha的生物炭(A3)在株高、有效分蘖、穗长、千粒重、实粒率和估计产量方面表现出最高的平均效果。然而，平均生物量产量最高的是25 MT/ha的生物炭(A2)。B1 (20 cm × 20 cm)的平均穗长最高，B2 (20 cm × 25 cm)的灌浆粒率最高，未灌浆粒率最低。B3 (20 cm × 30 cm)的株高、有效分蘖、生物量产量、估计产量和千粒重的平均值最高。最高的产量和投资回报率(ROI)在处理6(25公吨/公顷的生物炭在20厘米× 30厘米的种植距离)，表明增加生物炭的应用导致更高的产量在20厘米× 30厘米的种植距离。研究结果表明，施用生物炭可以在不同种植距离上促进自交系水稻的生长和产量。

The study aimed to assess the status of the coco geonet in Central Luzon, particularly Aurora, which comprises more than 90% of the region’s production. The study utilized a participatory method, and a value chain analysis framework was used to examine the roles of different key players. The value chain comprises input provision, farm production, processing, and marketing. Based on the results of the study, coco geonet processors received the biggest share in terms of both value addition and total cost. Nearly all coconut farmers initially obtained planting materials from other coconut farmers whose farms exhibited high-quality characteristics. These farmers utilize simple farming methods that have not changed in many decades. Coco geonet production consists of two processing stages: coco-coir production and coco-geonet weaving. The primary constraint for coco geonets is the lack of access to the institutional market. Customers for the coco geonets produced by Aurora’s value chain are currently scarce. Marketing links are necessary to add value to the husks. It is therefore recommended that the products be promoted, their market be developed, and their marketing potential be tapped to allow the industry to become lucrative. Inter-agency support is needed for the value chain to perform efficiently and effectively.

Poverty, food insecurity, and lack of employment opportunities are fundamental issues experienced in the rural Philippines. They were worsened by the COVID-19 pandemic, which adversely impacted vulnerable sectors. This study examined the potential and viability of mallard duck egg production in a rural community in the Philippines. Twelve (12) rural women in Licab, Nueva Ecija, received 482 heads of ready-to-lay mallard ducks (Itik Pinas breed) as part of the Department of Agriculture Regional Field Office III's livelihood initiatives. Data were gathered using a participatory research design through a household profile survey, focus group discussion, and descriptive statistics. The study findings showed that the respondents live below the poverty line and have an average monthly income of ₱2,083.33. The study revealed that during the 18 months of egg production, the recipients were able to harvest a total of 144,534 eggs. This provided the respondents with a gross income of ₱929,838.75 and a net gain of ₱341,156.89, corresponding to an average monthly net income of 1,579.43 per respondent. This allowed each respondent to improve their household income by up to 64.12%. Peak egg output was 76% or 60.33% on average. This study also showed the resiliency of rural women, who utilized locally accessible resources to reduce production costs.

This study delves into the factors that boost agricultural productivity while taking five macroeconomic variables into account. The investigated variables are agricultural productivity, which is used as the dependent variable, while employment in agriculture, gross capital formation, arable land, and rainfall are the independent variables. Employing an autoregressive distributed lags (ARDL) model, this paper examines the determinants of agricultural productivity in Somalia from 1991 to 2020. The cointegration between the model’s variables was verified using a bounds-testing approach to cointegration. Employment in agriculture was found to have both a short-run and long-run positive impact on agricultural productivity. Similarly, it was discovered that both gross capital formation and the availability of arable land had a favorable influence on agricultural productivity in the short and long run. Additionally, the study indicated a positive short-run and long-run correlation between rainfall and agricultural productivity, although this correlation is statistically insignificant at a five percent level. In the long run, the amount of available arable land has a positive impact on agricultural productivity. However, in the short run, this determinant has the opposite effect. Based on the results, the study advises the government, policymakers, and other concerned authorities to prioritize technological innovation and climate-smart agricultural systems to boost sector productivity.

Large numbers of crab shells are disposed of as food waste in the food processing process. Chitin nanofiber (CNF) refers to chitin extracted from crab shells in the form of ultrafine fibers that enable uniform dispersion in water. We explored the feasibility of using CNF materials as plant growth promoters. We investigated the effects of CNF application with fertilizer and its various application methods on the growth of the komatsuna plant cultivated in Entisols and Andosols with the application of CNF materials. The surface application of CNF materials had plant growth-promoting effects in both Entisols and Andosols. The topdressing treatment was more effective in promoting plant growth in Entisols. The inorganic nitrogen content absorbed by plants in the topdressing treatment was lower than that in the basal application treatments because the CNF added during the latter half of the cultivation period was not fully decomposed before the completion of cultivation. The calcium content of plants in the basal application treatment of CNF/protein/calcium carbonate was higher than that in the topdressing treatments, indicating that the calcium encasing the CNF was absorbed by the plants. The cultivation of plants with the application of CNF materials promoted nitrogen utilization efficiency and plant growth.

This study examines improved rice variety adoption and its welfare implications among small-holder farmers in South West Nigeria. A multistage sampling technique was used to select 300 rice-farming households from two selected states. The study used primary data retrieved with the aid of structured questionnaires. Data were analysed using a five-point Likert scale, a logistic regression model, and the multidimensional poverty index (MPI). The study showed that more than half (56%) of the farmers noted that the acceptance of improved varieties was easy, with a mean score of 3.5. The study also established that age (β = -0.0394; p < 0.001), farming experience (β = 0.0758; p < 0.001), and extension contact (β = 1.7203; p < 0.001) were the factors that influenced the adoption of improved rice varieties in the study area. The results of the MPI revealed that indigenous rice farmers were poorer than improved rice-farming households. Overall, 34% of improved and 54% of indigenous rice farming households are multidimensionally poor. MPIs of 0.11 and 0.21 were obtained for improved and indigenous farmers, respectively. The adoption of improved varieties was influenced by socioeconomic factors, and some households cultivating rice were MPI-poor. The study indicated that the adoption of improved varieties can result in improved productivity and reduce the prevalence of poverty in the study area.

This research aims to identify the barriers to the spread of integrated paddy and beef cattle farming and the influence of these barriers on Indonesian farmers’ acceptance of integrated farming. Quantitative methods were used to examine the barriers to integrated agriculture acceptance. A direct survey was conducted in which questionnaires were distributed to respondents. In addition, a research framework for the acceptance of integrated agriculture was developed using the technology acceptance model (TAM). Several data analysis methods were employed, including descriptive analysis, confirmatory factor analysis (CFA), and structural equation modelling (SEM). Data were obtained from 310 organic paddy farmers in Boyolali Regency, Central Java, Indonesia. The data were analysed using LISREL 8.8 software to assess the influence of barriers on the acceptance of integrated farming. SEM yielded the following results: x2 degree 1.77, GFI 0.92, AGFI 0.90, CFI 0.94, and RMSEA 0.06. As a result, we concluded that the goodness-of-fit index met the recommended criteria and that the model corresponded to the data provided, which allowed us to continue with the hypothesis testing. The results of hypothesis testing showed that the factors that significantly influenced the acceptance of integrated farming were barriers in the areas of production, knowledge, government, and economics. The practical implication of the research results is that by reducing barriers to production, knowledge, government, and economics, the acceptance of paddy and beef cattle integration can be increased.
