The main activities in the rural landscape are agriculture, involved natural resources management that compose the function of area as settlement, government services, social services and economy activities. These activities affected the rural landscape that changed plant diversities as well as carbon stock. The aim of this research was to evaluate biodiversity and carbon stock in the rural area of Cisadane Watershed. Two villages were defined on a purposive random sampling, i.e. Sukadamai and Bantarsari. The sampling plots were selected based on main land use type with size for tree was 20 m × 20 m, pole was 10 m x 10 m, sapling was 5 m x 5 m and seedling was 2 m x 2 m; with 3 replications. Similarly, other concentric plots were established. The number of plant species were counted, diameter at breast height (DBH) and plant height were measured. The analysis of carbon stock, plant diversity and the relationship was developed using Microsoft Excel and R 3.6.1 software. The results showed that main land use in Sukadamai and Bantarsari Village consisted of settlement area, farmland, mixed farming and palm oil plantation. In the research area where 106 species from 43 families that classified into 9 horizontal diversity based on function and 5 vertical diversity based on plant height. The values of Shannon-Wiener Diversity Index (H’) ranged 2,78–3,20. Estimated carbon stocks were 1,16–51,40 Mg ha−1 in research areas, respectively. These research concluded there was a negative correlation between species richness and diversity index with carbon stock in the village landscapes.ABSTRACTThe main activities in the rural landscape are agriculture, involved natural resources management that compose the function of area as settlement, government services, social services and economy activities.

Cover crop diversity under plantation area has potency to supply forage for animal farming. The research aim was to evaluate cover crop vegetation and to estimate plant production and quality under plantation at West Java. This research was conducted from May 2018 to April 2019 at public and private company around Bogor, Banten, Kuningan and Garut. In each area, there were selected 10 plots for plant identification with sample size was 50 cm x 50 cm. Biomass production and nutrient quality was sampled through 3 plots with sample size was 100 cm x 100 cm, forage was harvested and weighed then analyzed by proximate analysis. Diversity and biomass production were analyzed by R 3.6.2 software through Analysis of Variance(ANOVA) based on environment differences, then the significant results analyzed by LSD Test. The results showed that the highest biomass was sampled in Bogor i.e. 359 g m‑2 ±164.08 g m‑2 fresh weight and 71.22 g m‑2 ±45.91 g m-2 dry weight. Cover crop diversity varied around two to 32 species with percentage of area cover around 10-90%. Potential plants as forage were Panicum repens (lempuyangan), Paspalum conjugatum (jukut pahit) and Asystasia gangetica (ara sungsang). Dry matter content of composite forage was 18.3%-31.6%, crude protein was 4.57%-10.8%, crude fiber was 21.3%-25.7% and ashreached 11.2%-15.9%. It can be concluded that cover crop under plantation have potency to supply forage, especially in Bogor, however concentrate addition is needed to fulfil nutrient animal requirement due to the low quality forage.

Palm oil plantations have the potency to provide forage as a source of energy for livestock. The objective of this research was to estimate the production and quality of weeds under palm plantation as ruminant feed. Identification was conducted to find out information about botanical composition, production and nutritional content to estimate potential forage. The study was conducted using a randomized block design with 2 blocks of 6- and 8-years old palm and 10 sample plots. The research parameters were botanical composition, weed dominance and diversity, and also forage production potency. The results showed that 19 species from 11 families were found and dominated by gramineae. The weed botanical composition and diversity level was affected by oil palm plantation age. On the 8 years old oil palm plantation, the number of weed species and diversity level were decreased, reaching 10 species and H’ 2.41 while on the 6 years old were 13 species and H’ 3.14. Based on the type of weed, Paspalum conjugatum P.J. Bergius is a weed that has the potential to be used as the highest forage as ruminant animal feed with an estimated production of 730.42 kg ha-1 of fresh biomash. The estimation of weed production ruminant forage was dominated by grass that had up to 1.87 ton ha-1 of fresh biomash.

Gynura procumbens (Sambung nyawa) has been widely used as a herbal medicine since it is rich in bioactive compounds. Moreover, Gynura procumbens also has become a potential plant that control parasitic nematode infection. The research aimed to investigate the effect of G. procumbens on sheep performance, health status, and methane production. A total of twelve six-month-old lambs (ABW 11.27 ± 2.19 kg) were categorized based on live weight and fed one of feed treatments: wild grasses (40%) and concentrate (60%) (control/P0), P0 + 5% G. procumbens (P1), and P0 + 10% G. procumbens (P2). Feed intake, parasitic infection, and physiological status were measured weekly. G. procumbens at 5% level showed normal respiration rate, but the respiration and heart rates of lambs were abnormal. The 10% G. procumbens increased daily weight gain. G. procumbens addition up to 10% reduced the number of Strongyloides on feces and enteric methane emissions compare to control. It concluded that 5% G. procumbens can be used as an anthelmintic forage by improving health status, performance, and reducing methane emissions of sheep.

Jati Unggul Nusantara (JUN) (Tectona grandis L.f.) banyak diminati karena memiliki masa panen yang singkat. Dibalik keunggulan itu JUN memiliki sifat kayu yang kurang stabil. Kondisi tersebut dapat diperparah oleh serangan hama dan penyakit yang bersumber dari vegetasi yang telah ada sebelumnya. Sisa vegetasi di suatu pertanaman dapat menjadi penghubung bagi siklus kehidupan hama dan penyakit. Di kebun percobaan Universitas Nusa Bangsa (UNB) terdapat tunggul JUN yang dibiarkan tumbuh menjadi tegakan baru (terubusan). Tujuan dari penelitian ini adalah menginventarisasi hama dan penyakit pada daun terubusan JUN melalui pengamatan gejala kerusakan daun. Penelitian ini dilakukan pada bulan April – Juli 2021 di Kebun Percobaan UNB, Desa Cogreg, Kabupaten Bogor. Sampel pohon ditentukan dengan metode transek sepanjang 160 m. Pengamatan sampel daun dilakukan dengan cara dipetik kemudian diamati jenis dan luas tutupan gejalanya. Luas tutupan kerusakan pada daun tersebut diamati dengan bantuan bidang ukur berbahan mika plastik berukuran 20 x 20 cm. Hasil penelitian menujukkan 666 (86%) helai daun bergejala serangan hama dan/atau penyakit. Sebagian besar kerusakan ditimbulkan oleh penyakit daripada hama. Serangan penyakit yang ditemukan antara lain hawar, shot-hole, karat, embun tepung, karat, dan klorosis. Adapaun gejela serangan hama yang ditemukan yaitu defoliasi, leaf-miner, skeletonize, dan lekukan. Gejala hawar, shot-hole, dan defoliasi merupakan gejala yang paling sering ditemukan. Sementara itu, nilai keparahan tertinggi didapatkan pada gejala embun tepung, hawar, dan karat daun.
