“…Manure, such as chicken manure, is a commonly used basic fertilizer in agroforestry that supports the growth and metabolism of soil microbes as well as being a direct source of plant nutrients. The results of this study support the finding of Hidayat et al (2021) that the population and diversity of fauna and eukaryotic microbes (bacteria and fungi) are relatively diverse and predominate in oil palm areas in heap areas compared to disk areas due to a more favorable microclimate. In addition to organic matter, the exudates secreted by plant root systems can provide an advantage for the microbes (antagonists).…”

Peatland is a unique ecosystem with water saturation; peatland regulates hydrological processes, climate, environmental conditions, and biodiversity. Poor management practises regarding peatlands can lead to land degradation, and peatland degradation typically has negative effects. Recent tropical peatland research in Indonesia has predominantly revolved around the examination of the ecological consequences resulting from various management approaches. There is little study on farmers' agroforestry efforts to preserve and restore degraded peatlands. A comprehensive examination was undertaken to assess a range of facts, information, and scholarly articles pertaining to the practise of agroforestry on peatlands in Indonesia. The primary incentive for farmers to adopt agroforestry systems originates from their recognition of the impending scarcity of trees. By integrating intercrops with cultivated trees, farmers anticipate generating adequate money to fulfil their family's economic requirements. Farmers who choose intensive intercropping practises are motivated by market demand, whereas farmers who do not adopt this approach tend to favour crops that necessitate less rigorous management. The provision of governmental assistance holds significant importance, and there is a pressing need for additional guidance and support. The potential for rehabilitating degraded peatlands by the implementation of agroforestry practises of native tree species is considerable. Their growth patterns contribute to enhanced vegetative coverage, resulting in heightened moisture levels, reduced temperatures, diminished fire hazards, and improved peat soil quality. The relationship between the physiography of the land and the depth of the peat is directly associated with the patterns and components of agroforestry in peatland environments.

This research aimed to evaluate complete feed formulas with palm kernel meal (BIS) levels in concentrates fortified/enriched with probiotics on rumen fermentability. The material used is complete animal feed. The feed consists of forages (elephant grass, palm frond leaves) and concentrates (tofu dregs, fine corn, bran, palm kernel meal). 1% probiotics. In vitro analysis equipment, namely analytical scales, test tubes, oven, gauze, water bath, centrifuge, flask, filter, gauze, incubator, pipette dispenser, pH meter and Buchi brand rotary evaporator, flask, spectrometer, beaker glass, distillation tube, phenolphthalein, dropper pipette, Erlenmeyer flask, Conway cup. The materials used were rumen fluid, McDougall's solution, supernatant, 0.5 N NaOH, Vaseline, saturated Na2CO3, alcohol, 1 ml boric acid solution (0.005 N H2SO4), distilled water, 0.5 N HCl. This research used a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications. P0: 60% Forage (50% elephant grass + 50% palm fronds)/HPR + 40% concentrate (50% bran, 30% fine corn, 20% tofu dregs)/Const. + 0% BIS + 0% probiotics. P1: (HPR + Const) + 0% BIS + 1% probiotics. P2: (HPR + Const) + 10% BIS + 1% probiotics. P3: (HPR + Const.) + 20% BIS + 1% probiotics. P4: (HPR + Const.) + 30% BIS + 1 % probiotics. The variables observed were dry matter digestibility (KcBK), organic matter digestibility (KcBO), metabolic energy (EM), microbial protein production (PPM), and total VFA. Data were analyzed using variance (ANOVA) and if there was a significant effect, Duncan's further test was carried out. The results showed that complete feed based on palm kernel meal enriched with probiotics had a significant effect (P<0.05) on KcBK, KcBO, EM and PPM and had no significant effect (P>0.05) on the VFA value. Average KcBK 24.84-29.05%, KcBO 20.49-25.52%. EM 9.09-9.96 KCal, PPM 130.18 – 166.75mg/g, and VFA value 1.15-1.24 mM. This research concludes that using palm kernel meal up to 30% ported with probiotics in complete feed positively affects rumen fermentability in vitro.

Tanah merupakan salah satu media yang sangat penting bagi tumbuhan. Tanaman dapat tumbuh di beberapa tempat seperti di tanah gambut, tanah salin, dan tanah pasang surut yang mana tanah tersebut digolongkan sebagai lahan marginal yang memiliki karakteristik fisik dan kimia tanah yang secara langsung mempengaruhi tingkat kesuburan tanah. Tanah sebagai sumberdaya alam yang dipergunakan untuk kelangsungan hidup manusia, hewan maupun tumbuhan, tentu memberikan dampak terhadap kualitas tanah. Penggunaan tanah menjadi lahan pertanian, pemukiman maupun perkebunan tentu mendapatkan perlakuan yang berbeda-beda dari lingkungannya yang dalam hal ini dimungkinkan mempengaruhi reaksi tanah. Penelitian ini bertujuan untuk memberikan informasi reaksi tanah akibat perlakuan lingkungan yang berbeda. Penelitian ini merupakan penelitian deskriptif, reaksi tanah diamati dari pH tanah yang diambil dari dari beberapa lokasi. Metode pada penelitian ini meliputi pengumpulan sampel tanah dan penetapan pH tanah dengan cara elektrometri yang menggunakan alat pH meter. Hasil penelitian menunjukkan bahwa pH tanah vegetasi 6,2; pH tanah bakaran 7,8; pH tanah sawah 5,8; pH tanah organik 6,4; pH tanah pantai 6,2 dengan rentang kriteria pH sedang hingga tinggi dengan reaksi agak masam hingga agak alkalis.
