Evaluation of changeable agregat stability was done almost one year after application of biochar during rainy season 2010/2011 of three cyles maize planting in dryland of North Lombok. Three points of undisturbed soil samples in depth 0-20 cm were collected one month after maize harvest of previously addedbiochar land. Site of soil sample was treated by application of organic matter consisting of biochar coconut hust (BTK), biochar cow manure (BKS), one season application of manure (PKA), each season aplication of manure (PkB) and control (K : without soil amandement). The results showed that after one year application of biochar increased the limited value stability of soil agregat. The value was 61,37% and 61,18% for BTK and BTS, respectivel, while for treatment of PkA, PkB dan control gave value 58,44%, 66,62% and 57,11%. Increasing stability of soil agregat after application of organic soil amandement positively correlated with i the increase of soil organic and water soil retention. Therefore, experiment suggested that modification is needed for application biochar and manure in long period of maize cropping pattern in dryland of North Lombok

Improved management of dryland agriculture could be one strategy to increase cassava production in order to meet national demand particularly for food and bioetanol industry. A field experiment was carried out to evaluate the influence of biomass modification addition (biochar, cattle manure, and corn-straw) on the growth and yield of cassava grown on sandy soils of northern Lombok. The treatments tested were: without addition of organic biomas as control (M0); the straw was put in the lowest part of rhyzoshere, biochar in the middle and subsequently followed by manure mixed with soil on top (M1); biochar, cattle manure, straw were mixed thoroughly within rhyzosphre (M2); biochar and cattle manure were only mixed with soil (M3); the manure was put down in the bottom part of rhyzoshere, straw in the middle and subsequently followed by biochar mixed with soil on top (M4). Results of the research showed that modification of biomass addition (biochar, manure and corn-straw) within soil increased significantly the growth and yiled as a results of better nutrient retention compared to soil without organic addition. The yield was increased by 32 and 33% at M1 and M4 respectivelly and reached closed to 40% at treatments of both M2 and M3 (27 t/ha)

The aims of this study to were evaluate potential of biochar for improving several soil physical characteristics and yield of maize in a sandy loam soil of North Lombok during three cyles of sowing times (December 2010-October 2011). Five treatments, i.e. application of coconut sheld biochar (BTK), application of cow dung biochar (BKS), application of famyard manure only for one season (PKA), applications of farmyard manure each season (PKB) and control (K). Biochar application increased C-organic, and concentration of nutrient (N, P, K, Ca and Mg), absorption of N, P, K and seed yield. During three seasons, application of biochar led to higher C-organic content and more stabile compared with farmyard manure application. It indicated that biochar was potential for sequenstration of CO2, increased micro pores and soil water retention. Water holding capacity of biochar treatment was higher than PKA (application farmyard manure only for one season) and control. Maize plants showed positive response to biochar applications. Seed yield of maize for three cyles of seasons were 5,54 t/ha, 5,51 t/ha for BTK and BKS, repectively. Application of manure each season, application of farmyard manure at one season and control treatments yielded 5,62, 5,36 and 4,83 t/ha of maize seed, respectively

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.

Makalah ini mendiskusikan hasil kajian kualitatif peran kolaborasi dalam beradaptasi terhadap perubahan iklim di pulau-pulau kecil. Ketergantungan pulau-pulau kecil seperti Gili Trawangan (GT) pada industri pariwisata telah menyebabkan tekanan (stress) dan gangguan (perturbation) yang berdampak pada keseimbangan sistim sosial-ekologi di GT. Jika ekosistim pulau-pulau kecil terus mengalami degradasi maka kemampuannya untuk menyerap karbon semakin rendah sehingga tidak mampu mengurangi gas rumah kaca (GRK) yang terakumulasi di atmosfer. Upaya pengurangan emisi GRK dapat dilakukan dengan mempertahankan stok karbon yang ada di dalam tanah maupun di atas permukaan tanah dengan meningkatkan serapan melalui berbagai program reforestrasi. Kegiatan Pengabdian Masyarakat, yang dilaksanakan selama bulan Juli dan Agustus 2021, ditujukan untuk meningkatkan kapasitas kelompok kolaboratif masyarakat dalam beradaptasi terhadap perubahan iklim di pulau-pulau kecil, khususnya GT. Sedangkan secara khusus kegiatan ini dimaksudkan sebagai upaya penguatan kelompok kolaboratif melalui peningkatan pengetahuan, keterampilan, teknologi quantifikasi cadangan karbon di dalam tanah maupun di permukaan tanah, dengan memberdayakan sumberdaya lokal sehingga diharapkan mampu beradaptasi terhadap perubahan iklim. Proses penguatan kapasitas kolaborasi masyarakat GT dilakukan dengan pendekatan action learning untuk memastikan luaran yang direncanakan bisa dicapai:Pengetahuan kelompok kolaboratif masyakarat GT tentang konsep dan prinsip sekuestrasi karbon dan dampaknya terhadap kerusakan lingkungan semakin meningkat; ketrampilan tehnik mengestimasi jumlah cadangan karbon dalam tanah dan permukaan tanah meningkat; dan demplot sebagai laboratorium pelatihan lapangan bagi kelompok masyarakat dari desa-desa lain di KLU dapat diberdayakan.

Entisols are low fertility soils that require high doses of inorganic fertilizers to support plant growth. On the other hand, it was reported that biofertilizers can be applied to support plant growth. The purpose of this study was to examine the ability of bio-phosphate fertilizers to affect plant growth. The greenhouse experiment was arranged according to a completely randomized design, consisting of five treatments of different fertilization and each treatment was repeated four times. Experimental treatments were P1) control; P2) biological-phosphate fertilizer treatment; P3) treatment of NPK fertilizers; P4) integrated fertilizer treatment of 2 combinations of fertilizers (biological-phosphate & NPK); P5) integrated treatment of 3 combinations of fertilizers (biological-phosphate, NPK & organic). The dose of NPK fertilizer is 75% of the recommended dose. The experimental soil has a sandy loam texture, pH-soil 6.01, content of C-organic1.20%, N-total 0.09%, P-available 5.68 ppm and Kdd 0.31cmol/kg. The results showed that the application of a single biological phosphate fertilizer had no significant effect on plant growth compared to the control. A significant effect was obtained on integrated fertilization, both with two combinations of fertilizers (P4) and with three combinations of fertilizers (P5). The highest plant growth rate, with reference to the total dry biomass of plant shoots and roots, was obtained in treatment P5 with plant growth rates reaching 232.14% higher than the single treatment of biological fertilizers (P2), 53.70% higher than the single treatment of NPK fertilizers (P3) and 16.35% higher than the integrated treatment of two combinations of fertilizers (P4).
