Abstract

Title : Study on The Potency of Soil Microbes Isolated from Andisols of Dieng, Central Java,  as S-Oxidizing Biofertilizer Inoculant. The problem of nutrient deficiences tend to increase, including sulfur deficiency. The use of high purity NPK fertilizers stimulate sulfur deficiency in agricultural land. This problem can be corrected by the use of elemental sulfur accompanied with S-oxidizing biofertilizer. The study aimed to evaluate the potential of sulfur oxidizing microbial isolated from Andisols of Dieng Central Java as S-oxidizing inoculant. Andisols Dieng naturally contains high sulfur that allegedly inhabited many sulfur-oxidizing microbials. The research consisted of two experiments, each arranged in completely randomized design (CRD). Each experiment consist of two factors namely the kind of microbial isolated from Andisols Dieng and incubation time. The first experiment used Czapek-dox+elemental sulfur medium, while the second experiment used vermicompost as medium. The observed variables include soluble-S, bacterial density, biomass of fungi and medium pH. One isolate of bacteria (I1)and three isolates of fungi (F1, F2 and F3) taken from Andisol of Dieng showing their ability to oxidize sulfur in Czapek-dok agar medium. They were used as isolates in the experiment. The result of the first experiment showed that the oxidized sulfur increased with the length of incubation time as indicated by the increase of soluble-S, bacterial cell density or fungi biomass in the medium followed by the decrease of pH. The second experiment showed that the population of bacteria or fungi isolates and soluble-S of vermicompost were increased collaterally with incubation time. The fungi isolate of F2 have the highest potency as inoculant of S-oxidizing biofertilizer as shown by it ability to survive, grows and oxidize S both in Czapek-dox+elemental sulfur liquid medium as well as in vermicompost medium.

Abstract

Title : Zero Point of Charge of Various Organic Fertilizer : The Effect  on Soil Cation Exchange Capacity in Degraded Lands. Zero Point of Charge (ZPC) is an important variable in describing the mechanism of reversible surface charge primarily on weathered soil dominated by variable charge. ZPC is a certain pH when the surface charge is electrically neutral or zero (pHo). The presence of organic matter effect on the nature of the charge in the soil. Research goals include: 1). Obtaining information kinds of organic fertilizer with low of pHo, 2) Knowing the behavior of pHo and net charge of soil, 3) Knowing the influence of pHo on the soil cation exchange capacity. This study is an experimental functional relationship variables approach through experiments. The experiments were conducted at Greenhouse of Agriculture Faculty, Sebelas Maret Univercity. The basic design used was completely randomized design of a single factor. The treatment is done as follows: P0 = soil without the addition of organic fertilizers, P1 = soil with the addition of cow manure 5 tons / ha, P2 = soil with the addition of chicken manure 5 tons / ha, P3 = soil with the addition of quail manure s 5 tons/ ha, P4 = soil with the addition of goat manure 5 tons / ha, P5 = soil with the addition of bokashi 5 tons / ha, P6 = soil with the addition of rice straw compost 5 tons / ha, P7 = soil by adding compost hyacinth 5 ton / ha. P8 = soil by adding compost of Titonia 5 tons / ha and each treatment was repeated 3 times. Analysis of the quality of organic fertilizers include: levels of lignin and polyphenols, C/N, pH , pHo, humic acid and fulvic acid. The soil analysis includes the C-organic soil, total N, C / N, pH , pHo, CEC. The results showed that the zero point of charge (pHo) is the lowest organic fertilizer chicken manure (4.52). Obtained a close relationship between the difference in pH H2O with pHo with cation exchange capacity. Highest cation exchange capacity achieved in the treatment of chicken manure.

Abstract

Title : Potential Emission Of N2O from Various Types of Soil with Organic Material Addition. N2O is one of the greenhouse gases generated by agricultural activities which is currently highlighted. Amount of N2O is the least amount in the atmosphere, but it has a global warming potential 310 times compared to the global warming potential by CO2, and has a very long half-life time in the atmosphere is about 120-150 years old. Organic fertilization is considered one trigger for N2O emissions, but the other organic materials are needed by the soil as soil-forming material. Intensive research is needed to determine the effect of the organic material to N2O on various aspects including soil type, because Indonesia is rich in soil. Indonesia has 10 of the 12 soil types that exist throughout the world (Soil Taxonomy). This study aims to determine the N2O emissions in different types of soil which were variations of the addition of organic matter. This research was conducted with an experimental method using a completely randomized design.The main observation is the variable potential N2O emissions which analyzed by Soil Incubation method. The results showed variations of provision does not affect the potential of organic materials N2O emissions for 30 days. Soil types of the most releases N2O respectively are Alfisols, then Inseptisols and most minor releases N2O is Andisols.

Abstract

Title : Effect of Growing Media and NPK Fertilizer on Growth of Shorea Javanica. Cibodas botanical garden – LIPI had compost product based on organic waste material (litter, grass, twigs, and fruit) which were collected from garden. Compost was produced by two methods : using katalek bioactivator and natural compost without bioactivator. Utilization of compost as growing media at nursery unit botanical garden was not optimal. The objective of this research was to determine the ability of compost from botanical garden as a growing media for seedling collection at Cibodas botanical garden. This study was conducted using a Randomized Block Design (RAB) with six treatments and four replications using Shorea javanica as plants indicator. Three types of growing media (top soil, natural compost and katalek compost) were applied for the treatment with the addition or non addition of NPK fertilizer. However, control treatment was made from top soil without addition of NPK. The data showed that both natural compost and katalek compost were demonstrated better result than top soil growing media. Katalek compost without addition of NPK fertilizer gave significantly different result at enhancement of plant height, leaf number, and dry weight if compared with control.
