Potatoes (Solanum tuberosum L.) which are comonly grown in the highland with Andisols require organic and inorganic fertilizers to maintain soil health and increase yield. The purpose of field experiment was to obtain information on the effect of vermicompost with and without NPK fertilizer on soil acidity, soil phosphor (P) availability and P uptake in potatoes shoot; as well as yield and quality of tuber. The experimental design was a randomized block design with eight treatments and three replication. The treatment consisted of a combination of vermicompost doses (5 and 10 t/ha) with NPK fertilizer doses (0; 0.5 t/ha and 1 t/ha). The two control treatments were 1) without fertilizer and 2) the method of fertilizing local farmers included 10 t /ha chicken manure and 1 t/ha NPK fertilizer. This experiment verified that vermicompost and NPK fertilizer increased plant height as well as soil P availability and acidity compared to those of control. Vermicompost has not yet substitute chicken manure to obtain the same tuber production although the percentage of marketable tuber was quite similar. Keywords : Andisols, NPK Fertilizer, Phosphorus, Potato, Vermicompost.

A mixture of andisol soil and foundry sand as Ni2+ ion adsorbent was studied in this research. Andisol soil and foundry sand were activated using 3M NaOH. The characterizations of adsorbents were carried out by Fourier Transform Infrared Analyzer (FTIR), Scanning Electron Microscopy-mapping Energy Dispersive X-Ray (SEM-EDX), and Surface Area Analyzer (SAA). The mixture was made by mixing andisol soil and foundry sand with various compositions of 100:0, 75:25, 50:50, 25:75, and 0:100 (wt%). The adsorption of Ni2+ metal ion performed on pH solution of 3-7 and contact time of 10-110 minutes with the batch system. Based on the research, the optimum conditions for the adsorption of Ni metal in the adsorbent mixture of andisol soil and foundry sand were 75:25 (wt%) at pH 6 and contact time of 95 minutes with an adsorption capacity of 0.3967 mg/g and adsorption percentage 72.59%. Adsorption kinetics tend to follow pseudo-second-order. The type of adsorption isotherm is more dominant following the Langmuir isotherm. Nickel metal adsorption capacity in electroplating waste is 0.2777 mg/g.

“…The problem to develope cinchona in tropical countries, including Indonesia, is the less suitable habitat because this plant is originated from a high altitude and cold temperature growing areas in Andes Mountain, the South America (Central of Tea and Cinchona Research Gambung, 1995). Cinchona plants will grow well on andosol soil with rich nutrition, low bulk density, and high water holding capacity (Marbun et al, 2018). Meanwhile, the majority of the area in Indonesia is low-medium land with inceptisol soil type.…”

Cinchona (Cinchona ledgeriana Moens) is one of the important medicinal plants that have the potential to cultivate as herbal medicine. This plant grows well in highland areas. Developing cinchona plants in the marginal area needs effort and modification techniques such as planting legume cover crop (LCC) to maintain the humidity and supply nutrition by fertilizing. Vermicompost is one of the organic fertilizers with rich nutrition to support plant growth. This research aimed to observe the effect of a combination of Mucuna bracteata as LCC and vermicompost dosage on young cinchona growth in a marginal area. This research was carried out from September 2019 to March 2020 at the Ciparanje Experimental Station, Faculty of Agriculture, Universitas Padjadjaran. The experimental research was conducted using a Randomized Block Design (RBD) method, which consisted of 12 treatments which were a combination of legume cover crop (Mucuna bracteata) and vermicompost dosages (0 g, 200 g, 400 g, 600 g, 800 g, and 1000 g per plant), with four replications. The result showed that the doses of vermicompost fertilizer of 400 g per plant combined with M. bracteata as cover crop gave the highest value on the leaf number and stem diameter. In contrast, the best treatment for leaf chlorophyll content was 200 g per plant vermicompost without LCC planting. Thus, the application of vermicompost combined with the planting of Mucuna bracteata cover crop on young cinchona plants is strongly recommended.Keywords: Cinchona ledgeriana, Mucuna bracteata, organic fertilizer, plant growth. AbstrakTanaman kina (Cinchona ledgeriana Moens) merupakan tanaman obat-obatan penting yang sangat berpotensi untuk dikembangkan sebagai obat bahan alam. Tanaman ini dapat tumbuh baik di dataran tinggi. Penanaman kina di wilayah marjinal memerlukan berbagai modifikasi seperti pemberian tanaman penutup tanah (LCC) untuk mempertahankan kelembaban tanah dan pemenuhan nutrisi melalui pemupukan. Tujuan dari penelitian ini untuk melihat pengaruh kombinasi dari penggunaan Mucuna bracteata sebagai LCC dan dosis pupuk kascing pada pertumbuhan tanaman kina belum menghasilkan di wilayah marjinal. Penelitian ini dilakukan sejak September 2019 hingga Maret 2020 di kebun percobaan Ciparanje, Fakultas Pertanian, Universitas Padjadjaran. Rancangan percobaan menggunakan rancangan acak kelompok (RAK) dengan 12 perlakuan yang terdiri dari kombinasi tanaman penutup tanah (LCC) yaitu Mucuna bracteata dan pupuk kascing (0 g, 200 g, 400 g, 600 g, 800 g and 1000 g) per tanaman yang diulang empat kali. Hasil penelitian menunjukkan dosis pupuk kascing 400 g/tanaman yang dikombinasikan dengan Mucuna bracteate menghasilkan jumlah daun dan diameter batang tertinggi dibandingkan perlakuan lainnya. Sedangkan 200 g pupuk kascing tanpa LCC merupakan perlakuan dengan nilai klorofil daun tertinggi. Berdasarkan hasil tersebut, penggunaan pupuk kascing yang dikombinasikan dengan Mucuna bracteate sebagai LCC dapat meningkatkan pertumbuhan tanaman kina belum menghasilkan.Kata Kunci: Cinchona ledgeriana, Mucuna bracteata, pupuk organik, pertumbuhan tanaman.
