Abstract

ABSTRACT Application of biochar to agriculture soils has been considered as means to improve soil quality and carbon sequiestration. Therefore, the understanding of chemical and physical properties of biochars is important to identify suitable use of biochar for improving soil fertility and carbon sequestration. Biochars were produced from phyrolizing five different feedstock from crops residues (rice straw- BPJ, rice husk- BPS, maize cobs- BJT, peanuts shell- BKC and soybean residues-BKE). Using muffle furnace heating under 400oC. The potential nutrients retention of those biochars in particular for NH4+, K+. Ca++, dan Mg++. was tested. througha leaching experiment established in Soil Physic laboratory at Faculty of Agriculure, University of Mataram . The physicochemical properties of biochars were likely varied among fives feedstocks. The biochars derived from soybean residues (BKE), peanut biomass (BKC) and maize cobs (BJT) contained higher mutrients (i.e. C, N, K, Ca and Mg) compared to biochars produced from rice straw (BJP) and rice husks (BPS). Total-C of BKE, BKC dan BJT were 51,73; 57,36 dan 53,53 % respecively. The variation of phyisicochemical properties from different biomass strongly related to different nutrient retention whenever the biochars are applied in soils. Biochars produced from legume crops biomass such as soybean and dan peanuts werethe highest nutrients retention, followed by maize cobsand rice straw biochars. Unde glass house test, the tree biochars namely BPS, BJT and BKE have similar effect on N,P, K uptake as well as to dry weight biomass.

Abstract

ABSTRAK Produktivitas tanah yang rendah, miskin bahan organik tanah, defisiensi N, kemampuan meretensi air rendah merupakan karakteristik tanah bertekstur lempung berpasir yang menjadi faktor pembatas terhadap ketersediaan hara dalam tanah. Untuk mengatasi permasalahan tersebut, maka diperlukan pembenahan tanah seperti penggunaan biochar dari berbagai limbah pertanian (batang tembakau, tempurung kelapa dan sekam padi). Penelitian ini bertujuan untuk mengevaluasi pengaruh residu biochar dan dosis nitrogen terhadap pertumbuhan dan hasil tanaman kedelai pada tanah bertekstur lempung berpasir. Metode penelitian yang digunakan adalah metode eksperimental yaitu dengan melakukan penelitian di Rumah Kaca. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) pola faktorial terdiri atas dua faktor yaitu Biochar dan Dosis Nitrogen. Biochar terdiri atas empat perlakuan yaitu: B0 (tanpa pemberian biochar), B1 (Biochar batang tembakau), B2 (biochar sekam padi) dan B3 (biochar tempurung kelapa) sedangkan Nitrogen terdiri atas tiga takaran yaitu: N0 (tanpa pemberian N), N1 (50 kg/ha) dan N2 (100 kg/ha). Masing-masing perlakuan diulang tiga kali sehingga diproleh tiga puluh enam pot percobaan. Hasil penelitian menunjukkan bahwa, masih ada pengaruh residu perlakuan pemberian biochar dan Nitrogen terhadap beberapa sifat kimia tanah yaitu kandungan C-Organik tanah, kadar N-Total tanah dan pH tanah. Residu perlakuan pemberian biochar ke dalam tanah memberikan pengaruh terhadap pertumbuhan tanam yakni jumlah daun dan jumlah biji. Dari semua perlakuan biochar, residu biochar batang tembakau paling tinggi memberikan pengaruh yang berbeda nyata terhadap beberapa parameter tanah yaitu pH, C-Organik, N-Total, Jumlah daun dan Jumlah Biji. ABSTRACT Low soil productivity, poor soil organic matter, N deficiency, low water retention ability is characteristic of sandy loam textured soils become a limiting factor on the availability of nutrients in the soil. To overcome these problems, it is necessary to reform the ground such as the use of biochar from various agricultural wastes (stem tobacco, coconut shells and rice husks). This study aimed to evaluate the residual effect of biochar and doses of nitrogen on the growth and yield of soybean crops in sandy loam soil. The method used is the experimental method is to conduct research in the Greenhouse he design used was a completely randomized design (CRD) factorial design consisting of two factors: Biochar and nitrogen doses. Biochar is made up of four treatments, ie: B0 (without giving biochar), B1 (Biochar tobacco stems), B2 (rice husk biochar) and B3 (biochar coconut shell) while Nitrogen consists of three doses, namely: N0 (without giving N), N1 (50 kg / ha) and N2 (100 kg / ha). Each treatment was repeated three times so diproleh thirty-six pot experiment. The results showed that, there is still residual effect of biochar treatment provision and Nitrogen on some chemical properties of soil organic C content of the soil, levels of N-total soil and soil pH. Treatment residues into the soil biochar provision giving effect to the growth of the plant leaf number and the number of seeds Of all the treatments biochar, biochar residues highest tobacco rod provides a significantly different effect on some soil parameters, namely pH, organic C, N-total, number of leaves and the amount of seeds.

Abstract

ABSTRAK Cabai merah (Capsicum annum L.) merupakan tanaman hortikultura yang kaya kandungan gizi bermanfaat, seperti protein, kalori, lemak, karbohidrat, kalsium dan minyak esensial.Penelitian ini bertujuan untuk mengetahui pengaruh dari perlakuan aplikasi biochar, pupuk kandang dan campuran keduanya terhadap pertumbuhan dan hasil tanaman cabai merah yang ditanam pada bedeng permanen.Penelitian dilakukan di Desa Batujai Kecamatan Praya Barat Kabupaten Lombok Tengah pada bulan April sampai dengan September 2015.Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan 7 perlakuan yang diulang sebanyak 3 kali, yaitu K0: Kontrol, B10: Biochar 10 ton/ha, PK10: Pupuk Kandang 10 ton/ha, B5PK10: Campuran biochar 5 ton/ha dan pupuk kandang 10 ton/ha, B10PK5:Campuran biochar 10 ton/ha dan pupuk kandang 5 ton/ha,B15PK5: Campuran biochar 15 ton/ha dan pupuk kandang 5 ton/ha serta B5PK15: Campuran biochar 5 ton/ha dan pupuk kandang 15 ton/ha. Hasil penelitian menunjukkan bahwa perlakuan campuran B5PK15 memberikan pengaruh yang nyata terhadap tinggi tanaman cabai merah (21 HST, 28 HST, dan 35 HST) dan B15PK5 memberikan pengaruh nyata terhadap jumlah dan berat buah pertanaman. Namun umur mulai berbunga dan berbuah, serta berat berangkasan tanaman cabai merah, untuk semua perlakuan tidak menunjukkan perbedaan yang nyata. ABSTRACT Red peppers (Capsicum annum L.) is a horticultural plant rich in beneficial nutrient, such as protein, calories, fat, carbohydrates, calcium and essential oils. This study aims to determine the effect of biochar application, manure and mixing both of biochar and manure on the growth and yield of red pepper grown on permanen raised beds. The study was conducted at Batujai Praya Barat, Central Lombok. Experiment was conducted from April to September 2015. The experimental design used was a randomized block design (RBD) with 7 treatments repeated 3 times, i.e K0: Control, B10: Biochar 10 ton/Ha, PK10: Manure 10 ton/Ha, B5PK10: Mixed biochar 5 ton/Ha and Manure 10 ton/Ha, B10PK5: Mixed biochar 10 ton/Ha and Manure 5 ton/Ha, B15PK5: Mixed biochar 15 ton/Ha and Manure 5 ton/Ha and B5PK15: Mixed biochar 5 ton/Ha and Manure 15 ton/Ha. Result showed that treatment B5PK15 had a significant effect on plant height at 21, 28 and 35 days after planting and B15PK5 significant effect on the number and fruit fresh weight per plant. Flowering and fruiting time, and biomass weight, were not significantly different for all treatments.
