Abstract

Integrated cattle–oil palm farming systems (SISKA) have been widely promoted in Indonesia, yet quantitative information on the forage potential of plantation understory vegetation remains limited and site-specific. This study assessed the composition, dominance structure and dry-matter (DM) attributes of understory vegetation in smallholder oil palm plantations (<10 years old) managed under a cattle–oil palm integration scheme in Tanah Laut Regency, South Kalimantan, Indonesia. Vegetation was sampled using twenty 1 × 1 m quadrats per site. For each species, relative density (RD), relative frequency (RF) and a simplified Importance Value Index (IVI = RD + RF) were calculated. Palatability was confirmed by direct observation of cattle intake, and DM content was determined by oven-drying herbage samples to constant weight. A total of 12 species from 7 families were recorded, consisting of grasses (Poaceae), sedges (Cyperaceae), legumes (Fabaceae) and broad-leaved forbs. The understory was strongly dominated by grasses, with Axonopus compressus showing the highest RD (60.36%), RF (16.67%) and IVI (77.03), and a relatively high DM content (33.51%), making it the keystone species in the ground layer. Almost all species (11 of 12; 92%) were classified as palatable to cattle, while only Peperomia pellucida was rejected and contributed negligibly to DM due to its low abundance and very low DM percentage (5.78%). The coexistence of productive grasses, nitrogen-fixing legumes and various forbs indicates a moderately diverse understory community that can provide a continuous, though heterogeneous, forage supply. These findings provide a site-specific, vegetation-based baseline for estimating forage DM potential and designing grazing strategies in SISKA systems, contributing to more productive and sustainable cattle–oil palm integration in Indonesia.

Abstract

This community service program addressed high feed costs and the underutilization of crop and slaughter by-products among goat-keeping households in Tanah Laut Regency, Indonesia, by introducing fermented complete feed made from corn cobs and hygienically processed bovine rumen digesta. The program aimed to strengthen farmer self-reliance while reducing open burning and the disposal of residues through a participatory action approach that iteratively combined co-design, hands-on training, on-farm application, evaluation, and refinement. Activities included orientation on feed management and waste-related issues, group mentoring on planning and record-keeping, practical production sessions using locally available inputs, and a thirty-day feeding trial on partner farms. Product quality was supported by simple process control and laboratory proximate analysis, which indicated a semi-dry fermented feed with moderate protein and high carbohydrate content, as is typical of upgraded crop residues. Goats readily consumed the feed, and farmers consistently reported improved appetite and palatability during the trial. Post-training surveys found that seventy-five percent of participants could independently reproduce the fermentation process and integrate it into routine management. Overall, the program demonstrated that converting corn cobs and rumen contents into fermented feed is feasible and acceptable at the farm level, supports skill adoption, and contributes to a zero-waste pathway. Follow-up monitoring will focus on batch consistency, spoilage prevention, feed intake, weight gain, and feed efficiency to document sustained impacts.Program pengabdian kepada masyarakat ini menanggapi tingginya biaya pakan dan belum termanfaatkannya limbah pertanian serta hasil samping rumah potong hewan di kalangan peternak kambing sekala rumah tangga di Kabupaten Tanah Laut, Indonesia, melalui penerapan pakan fermentasi berbahan tongkol jagung dan isi rumen sapi yang diproses secara higienis. Tujuan program adalah meningkatkan kemandirian peternak dalam penyediaan pakan, sekaligus mengurangi praktik pembakaran dan pembuangan limbah dengan mengubahnya menjadi pakan bernilai guna. Metode yang digunakan adalah partisipatif berbasis pemberdayaan yang dijalankan berulang melalui perancangan bersama, pelaksanaan, evaluasi, dan perbaikan. Kegiatan meliputi sosialisasi manajemen pakan dan isu lingkungan, pendampingan perencanaan serta pencatatan, pelatihan praktik produksi pakan fermentasi menggunakan bahan lokal, analisis proksimat produk, dan uji pemberian pakan selama tiga puluh hari pada peternakan mitra. Pakan hasil pelatihan dikonsumsi dengan baik oleh kambing dan peternak melaporkan peningkatan nafsu makan serta palatabilitas selama masa uji. Survei pascapelatihan menunjukkan bahwa tujuh puluh lima persen peserta mampu memproduksi kembali pakan fermentasi secara mandiri dan menerapkannya dalam manajemen rutin. Secara keseluruhan, program menunjukkan bahwa pemanfaatan tongkol jagung dan isi rumen sebagai pakan fermentasi layak diterapkan di tingkat peternak, memperkuat adopsi keterampilan, dan mendukung pendekatan zero-waste; pendampingan lanjutan akan diarahkan pada konsistensi mutu, pencegahan kerusakan, konsumsi pakan, pertambahan bobot, dan efisiensi biaya pakan untuk memastikan keberlanjutan dampak.
