Abstract

The obstacles that caused the declining of rice production is due to the reduction of soil fertility status. Various efforts were made to increase the production such as intensification and expansion in rice farming system. SRI cropping systems an alternative technique for improving soil productivity following maintaining water uses under an aerobic condition which exaggerated the raising of microorganisms activities in soil and improving the availability of nutrients particularly nitrogen status.This study was aimed to examine the impact of SRI system on mineral N status along with the population of soil bacteria which involving in nitrogen dynamic. The research was conducted in October 2015-March 2016 in Kepanjen-Malang using Randomized Block Design with 4 treatments and 4 replicates. Soil sampling was conducted at 0 and 100 Day After Planting (DAP) collecting at a depth of 0-20 cm and 20-40 cm. Measured soil parameter was including pH, organic-C, mineral N (NH4+ and NO3-). Soil bacteria are identified using plate count method (spread plate) for estimating their population. Analysis of Variance (ANOVA) was used followed by Duncan test at 5% level along with correlation and regression analysis.The results showed that the SRI cultivation system can increase the mineral N at the level of 14.09 ppm compared to their initial value, amounting to 57.48 ppm of Nitrate and the bacterial population at the level of 6.25 x 108 cfu g-1. The best treatment was found under the combination of NPK (15-15-15) and biofertilizer yielded at 8.42 t ha-1. Multivariate analysis results indicate that P0 treatment significantly different with treatment P1, P2, and P3. However, the treatment of P1 were not significantly different P3.

Abstract

Vegetations accumulate carbon (C) from the atmosphere in the form of tree biomass, producing litter which then becomes the main input of soil organic matter. The accumulation of soil organic matter provides food and energy for soil macrofauna to help maintain soil fertility. Total C accumulation is affected by land use changes which can then reduce soil ecosystem and ecological functioning. This study examined the impact of land use conversion from monoculture sugarcane to a tree-based agroforestry system. The results showed that the land use changes affected soil texture, bulk density, soil organic matter, and total C sequestration. The total C sequestration under 5 years old sengon (Paraserianthes moluccana) agroforestry system was almost double that of total C sequestration 2 times or even 5 times ratooned monoculture sugarcane (Saccharum officinarum). The lowest IVI of soil macrofauna was detected under 1-year-old sengon agroforestry system before it was getting lowered under a longer period of cultivation, whilst the highest population was detected under 5 years old Sengon. Multivariate analysis, which was employed to detect the impact of land use changes, could cluster and group the effect of treatments based on selected variables such as soil physical, chemicals, and soil macrofauna structure and diversity, which accounted for 97.75% of the total variance. There was a strong relationship between the abundance of Formicidae sp. and Carabidae sp.

Abstract

This research aims to describe plants diversity having local wisdom value for Ot-Danum Dayak people, Tumbang Payang village and Tumbang Kania village, Central Kalimantan. The result reveals that since a long time ago, Ot-Danum Dayak people truly depend on natural resources to meet various daily needs. The vast majority of subsistence and society's income are form forest plants product. Plant diversity can provide food product for society, can produce various plants to be consumed and also produce alternative income sources, such as exploited for food, medicine, fermentation, tonic, cosmetic, building material and etc. However, the existing plant diversity is endangered since deforestation and forest degradation, and even there are many lesser-known species. Therefore, it needs to quickly find the information about the species to conservation effort, given the existing forest resource has a big potential to be developed and cultured to the species through domestication and providing a genetic resource for hybridization and selection.

Abstract

The problem in the production of biofertilizers is that raw materials are cheap, easy to get and apply. Another problem is determining the viability of the consortium microbes in a biofertilizer formulation. This study aims to determine the bacterial viability of various liquid media originating from organic waste as a liquid biofertilizer carrier. Three indigenous bacterial strains under consortium for phosphate soluble (Pantoea ananatis strain 53 (BC32)), non-symbiostic Nitrogen fixation (Bacillus licheniformis strain S45) and stabilizing soil aggregate (Pseudomonas plecoglossidastrain PR19) were added to liquid biofertilizer. The study evaluated 10 treatments using a randomized design with three replicates. The treatments are as follows: Peptone,molasses, Compost wash from seaweed waste, Vermiwash, molasses + glycerol, compost wash from seaweed waste + glycerol, vermiwash + glycerol, molasses + PEG (PolyEthylene Glycols)1%, compost wash seaweed waste + PEG 1%, and Vermiwash + PEG 1%. This biofertilizer formulation (liquid) was kept for 16 weeks at optimumpH 5.5. VP3 (Vermiwash made from vermicompost + PEG 1%) treatment showed thebest viability of bacterial strains during the 16-week storage period. The pathogenicitytest using green bean seeds Vima-1 showed that all liquid formulations of biological fertilizers with the three consortium bacterial isolates did not show signs of diseases and demonstrated better growth than the control treatment. Compared to other treatments, the best growth of bacterial strains was detected with MP2 (Molasses + glycerol) treatment. Formulations using vermiwash and PEG appear to maintain bacterial viability in the formulation effectively. However, the formulation of molasses and glycerol exerts a stimulating effect on sprouts growth.

Abstract

The water content of the soil in Jatikerto is 32,02%. As it is supported by clayey loam soil texture, the soil is able to absorb more water, but the water in the soil cannot necessarily be available to the plants. One effort to maintain the availability of ground water can be done with the soil amendments materials such as biochar. This study used three types of biochar, i.e. rice husk, coconut shell, and wood with each contained three doses (15, 30 and 45 t ha-1). This study used ten treatments with two factors consisted of types and doses of biochar. Soil sampling was conducted at 2 points on the array and on an array, and each point was conducted on soil depth of 0-20 cm and 20-40 cm. The variables measured were soil texture, soil bulk density, soil porosity, pore space distribution, pore fast drainage, pore slow drainage and pores water available. The results indicated that treatments of types and doses of biochar did not change the texture of the soil. The highest soil bulk density contained in biochar types of wood biochar dose of 30 t ha-1 (1,20 g cm-3), while for soil particle density was not significantly influenced by the biochar treatments. The average value of the highest porosity was measured on the type of wood biochar dose 15 t ha-1 (47,54% vol). The highest pore fast drainage contained in biochar types of coconut shell biochar dose of 30 t ha-1 (20,80% vol), while for the highest available pore water was on the type of coconut shell biochar dose 45 t ha-1(21,55% vol). The highest pore slow drainage was on the type of wood biochar dose 30 t ha-1 (29,03% vol).

Abstract

Based on data from Malang District in 2015, Pakisaji has the potential to reach 17,000 tons of rice yield. However, it has some hindrance in water availability that affects rice planting planted using conventional methods. One of the rice cropping system that can be used to reduce water usage is SRI (System of Rice Intensification) method. The goal of this study was to know the content change of  soil N, P, K due to application of NPK 15-15-15 fertilizer combined with biofertilizer using SRI method and determine the level of crop production. The results of this study showed that the application of NPK 15-15-15 fertilizer combined with biofertilizer in SRI method produced the highest soil nutrient content such as total nitrogen (0.29%), P availability (26.31 ppm), and K availability (0.58 me 100 g-1 especially at the depth of 0-20 cm. The combination of NPK 15-15-15 fertilizer and biofertilizer applied in SRI method obtained the highest yield at a weight of 1000 seeds (30.31 g) and yield of dry grain harvest (8.4 t ha-1).

Abstract

The development of forest plantations into one of forestry enterprises is seen as an activity that can reduce emissions by increasing carbon stocks. Measurement of carbon stocks needs to be done to obtain data of carbon stocks stored in a field so that it can be calculated emissions that are released into the atmosphere when there is a fraction of the land cover. In this study, carbon stocks was calculated by estimation method using allometric equations that had been made in previous studies and devoted to the stands of teak (Tectona grandis Linn. F), litter and soil. The study was conducted by dividing the teak plantation with various age classes (KU) of teak plant, ranging from KU 1 to KU 6. KU 1 has age 1 - 10 years, KU 2 has age 11-20 years, KU 3 has age 21 - 30 years old, KU 4 has age 31 - 40 years old, KU 5 has age 41-50 years and KU 6 has age 51 - 60 years old. The value of carbon stocks in the teak stands in each equation increased with the increasing age of the teak stand. Carbon deposits in teak forests increased by 3.96 t ha-1 to 5.54 t ha-1 annually. Teak forests can reduce CO2 in the air, and the greater the age of teak the greater CO2 in the air can be reduced. Teak forests can reduce CO2 in the air by 14.45 t ha-1 to 20.26 t ha-1 annually. Basal area value on teak stands affects 64% of litter biomass values. The higher the basal area value the litter biomass value will increase. Basal area values of teak forests in KU 1 to KU 6 ranged from 5.63 m² ha-1 to 50.36 m² ha-1.
