Abstract

The Baramban Farmers Group, since 2014, has been carrying out healthy vegetable farming with vegetable products that have been certified Prima 3. However, until now, the management of healthy vegetable farming by the Baramban Farmers Group in Banuhampu District, Agam Regency has not experienced much development in farming because it has not created a broad market with prices that favor the welfare of farmers. Strengthening farmer institutions in marketing healthy vegetables is thus very important and have become an essential element in developing healthy vegetable agribusiness in local, national, and even global markets. The method used is counseling, coaching and mentoring. This service activity is planned to be carried out over the next five years, starting with building a cooperation agreement with the Baramban farmer group starting in 2020. Several alternative solutions to solve the problems of healthy vegetable farmer group partners proposed and agreed upon by the Baramban Farmer Group are: a. Carry out mentoring activities for healthy vegetable farmers by transferring resources from universities through integrated science an agribusiness perspective, b, empowering farmers based on group institutional strengthening to build collective action that is independent of farmers to drive healthy vegetable markets, c. Facilitate farmers to create healthy vegetable market segments through modern markets and online markets with information technology 4.0 and 4. Building partnerships with Transmart as a modern market on a national scale and has a global-scale marketing network. The conclusion is that farmer groups are willing to become partners of the Community Service Team in a community partnership program scheme to help businesses develop.

Abstract

Rubber seeds (Hevea brasiliensis) are underutilized plant by-products with potential for food and feed applications, but cyanogenic glycosides remain an important safety concern. This study investigated processing-associated changes in the metabolite profile of rubber-seed flour using untargeted liquid chromatography–high-resolution mass spectrometry (LC–HRMS). We evaluated four treatments: unprocessed whole seeds (A), soaked and boiled seeds without the seed coat (B), soaked and boiled seeds followed by oil pressing (C), and soaked and boiled seeds with the seed coat retained (D), with three biological replicates per treatment. After spectral-quality assessment, contaminant removal, and plausibility review, 39 putative metabolite annotations were retained for multivariate analysis. Principal component analysis separated the unprocessed samples from the processed groups; PC1 and PC2 explained 35.0% and 19.6% of the variance, respectively. A two-component partial least-squares discriminant analysis model showed Q² = 0.630 and R² = 0.918, but leave-one-out cross-validation classified only 50% of samples correctly, indicating limited predictive performance in this small dataset. The processed groups showed substantial overlap, suggesting that their profiles were more similar to one another than to the unprocessed control. VIP-ranked features included glycerolipids, amino-acid-related compounds, and fatty acids; these were treated as putative annotations rather than definitive identifications. Linamarin was assigned in only one sample and lacked MS/MS confirmation, so its presence and any effect of processing on cyanogenic risk remain unresolved. Overall, soaking and boiling were associated with changes in the measured metabolite profile. Targeted quantification of linamarin and hydrogen cyanide, confirmation of key metabolite annotations with authentic standards and MS/MS, and validation in a larger factorial experiment are required before practical safety or nutritional claims can be made.
