Abstract

Adding organic fertilizer such as vermicompost can be done to overcome the deficiency problem of soil organic matter. One of the worm species which can be used in vermicomposting is Eudrilus eugeniae. Purpose of this research was to know how the combination of cow dung and rice straw impacts vermicompost quality from organic carbon, N, P, total K, urease enzyme activity and vermicompost production. Treatment that used in this research is randomized completely design with 4 treatments. The treatments are P1: feed 400 g of cow dung, P2: feed 400 g of rice straw, P3: feed 280 g of cow dung and 120 g of rice straw, and P4: feed 140 g of cow dung and 60 g of rice straw. The research result shows that real treatment impacts all parameters on the produced vermicompost. Production result is determined by ratio value of output/input (O/I). Quality and production of vermicompost on P4 is a treatment with the best result. It is because the combination of cow dung and rice straw gives a relatively complete macro nutrient result and the higher feed dose will gives higher vermicompost production.

Abstract

Mycorrhizal biofertilizers contain fungi that are capable of entering and symbiotic mutualism into plant roots and increasing the ability of plants to absorb nutrients. Fertilizer effectiveness testing is needed to protect consumers from the adverse effects of using biofertilizers. This study aims to determine the effectiveness of MZ2000 mycorrhizal biofertilizers and to know mycorrhizal root infections in sengon seedlings in nurseries. The combination treatment of 30 g MZ2000 mycorrhizal biofertilizer with 5 g NPK fertilizer gave the best sengon growth results although it was not significantly different in several parameters compared to the combination treatment of MZ2000 fertilizer dosage and other NPK fertilizers, with the value of agronomic relativity (Relative Agronomic Effectiveness / RAE) 580.80% for high growth and 288.72% for growth in stem diameter and incremental benefit cost ratio (IBCR) analysis of farming by 2.48. So that the dosage of the combination treatment of mycorrhizal biofertilizers and NPK fertilizer is most agronomically and economically effective. With the effectiveness of the fertilizer, the MZ2000 mycorrhizal biofertilizer can be declared to have passed the field effectiveness test.

Abstract

Mycorrhizal bio-fertilizers can maintain land productivity and are environmentally friendly. This study aims to analyze the effect of mycorrhizal biofertilizer on the growth of shallots (Allium cepa var. Aggregatum) and to determine root infection and its effect on soil N, P, K levels. The experimental design used was a completely randomized design (CRD). The treatment of biological fertilizer testing is carried out based on the Regulation of the Minister of Agriculture No. 70 / Permentan / SR. 140/10/2011, consisting of 6 treatments (AF) as follows: A) control, B) standard fertilizers, C) mycorrhizal biological fertilizers, D) mycorrhizal biological fertilizers + 25% standard fertilizers, E) mycorrhizal biological fertilizers + 50% standard fertilizer, F) mycorrhizal biological fertilizer + 75% standard fertilizer. There were 5 replications so that 30 experimental units were obtained. Mycorrhizal bio-fertilizers can reduce the need for standard fertilizers (PS) to 25% to 50%. The combination of biological fertilizer of 2.5 g / plant with 50% PS produces the best plant height and biomass weight, but economically it is recommended to use 25% PS. The treatment applied to mycorrhizae had a very high root infection value, which was above 75%. The types of spores that were successfully associated were Acaulospora sp., Glomus etunicatum, and Glomus sp. The application of mycorrhizae resulted in an increased response of 14.91% for P-available Latosol, while for K-dd and N-total there was no significant effect.

Abstract

Increasing the amount of avocado production is influenced by the effectiveness of fertilization. Fertilization is the most important thing in agriculture to improve plant nutrition, achieve high yields, and change the soil environment. The use of biofertilizer is needed to improve the quality and quantity of plants and reduce the chance of land degradation. The experimental design used was a randomized block design (RBD) with a single factor in fertilization. This RAK has nine treatment levels, namely: 1) control (without NPK and biofertilizer), 2) 100% NPK fertilizer, 3) 50% NPK fertilizer, 4) 100% NPK fertilizer + 100% biofertilizer, 5) NPK fertilizer 100% + 50% biofertilizer, 6) 50% NPK fertilizer + 100% biofertilizer, 7) 50% NPK fertilizer + 50% biofertilizer, 8) 100% biofertilizer, 9) 50% biofertilizer. This treatment was repeated five times. The use of NPK as a combination and substitution of biofertilizer. The basic fertilizer used, namely manure as much as 1.25 kg/tree. Overall, the best treatment was a combination of NPK fertilizer and biological fertilizer, especially in the P3 treatment, namely a combination of 100% NPK and 100% biological fertilizer. This can be seen in the vegetative growth of avocado plants and the soil's chemical and biological analysis, which have increased. Significant results occurred in plant height, the number of tertiary branches, total N, and soil invertase activity.

Abstract

Usaha pengendalian hama ulat grayak (Spodoptera litura) di tingkat petani masih mengandalkan pestisida sintetik. Tujuan penelitian adalah mengeksplorasi bakteri potensial pengendali hama ulat grayak (S. litura) dan menguji ketahanan bakteri potensial pada bahan pembawa kompos dan zeolit. Isolat tanah diisolasi dari tiga jenis sumber, yaitu sampel tanah daerah rhizosfer (padi, kelapa sawit, terung, jagung), sampel buah busuk (kakao, kelapa sawit, jambu air), dan sampel bangkai serangga (ulat api, belalang, kumbang tahi, kupu-kupu) yang diambil dari kawasan Dramaga dengan metode purposive sampling. Penelitian di laboratorium meliputi isolasi bakteri, uji patogenitas, pewarnaan gram, pengamatan morfologi koloni, uji toksisitas, uji biokimia, dan uji bahan pembawa. Berdasarkan penelitian ini didapatkan dua strain yang berpotensi sebagai agens biokontrol dengan kemampuan membunuh hama yang tinggi pada pengujian toksisitas tahap kedua, yaitu IRJ 10 (tingkat kematian 90%) dan ISU 4 (tingkat kematian 100%). Kedua isolat ini merupakan anggota genus Bacillus. Pada uji bahan pembawa kompos dan zeolit, penurunan jumlah sel bakteri pengendali hama paling tinggi adalah pada bahan pembawa zeolit dibandingkan dengan menggunakan bahan pembawa kompos. Jumlah sel bakteri pengendali hama pada masa penyimpanan 3 minggu masih di atas 108 CFU/g.KeywordsBakteri; Bahan pembawa; Ekplorasi; Agens pengendali hama; Ulat grayak (Spodoptera litura)AbstractThe effort to control the Spodoptera litura at the farm level still used synthetic pesticides. This research aimed to explore potential bacteria as biological control of S. litura and do viability test of potential bacteria on compost and zeolite carrier. Soil potential bacteria had been isolated from three sources, including rhizosphere soil samples (rice, oil palm, eggplant, corn), rotten fruit samples (cocoa, oil palm, water), and insect samples (fireworms, locusts, dung beetles, butterflies) taken from Dramaga area with the purposive sampling method. Stages of laboratory study include isolation of bacterial isolates, pathogenicity tests, gram staining, colony morphology observation, toxicity test, biochemical test, and viability test. Two strains that have potential as biocontrol agents with a high ability to kill pests in the second stage of toxicity testing are IRJ 10 (90% mortality rate) and ISU 4 (100% mortality rate). Both of these isolates are members of the genus Bacillus. The highest number of viability was found in zeolite carriers. The number of bacterial cells in the three-week storage period is still above 108 CFU/g.

Abstract

Soil properties such as physical, chemical, biological, microbiological and biochemical aspects affect on soil quality. Soil microbiological activities directly affect stability of ecosystems and soil fertility. The research aimed to determine soil microbial activities through soil enzyme activities and their relationship to total soil bacteria, soil microbial biomass, and soil chemical characteristics. The research was conducted at Laboratory of Soil Microbiology, Indonesian Soil Research Institute, Bogor from July 2015 to January 2016. Soil samples 0-10 cm depth were taken from organic and conventional farming of some commodities (tomato, carrot, maize, broccoli) from Bogor Regency, while those of rice were taken from Tasikmalaya Regency. Soil dehydrogenase, urease and cellulase activities were determined using some modified methods. The results showed that soil dehydrogenase and cellulase activities in organic farming were higher than those in conventional farming, whereas the soil urease activity in organic farming was lower than that in conventional farming. The total soil bacteria and soil microbial biomass were significantly and positively correlated with soil dehydrogenase, urease, and cellulose activities. Soil dehydrogenase, urease, and cellulose activities were very significantly and positively correlated with all soil characteristics tested, i.e. soil organic C, total N, potential P and K, available P and K, CEC, and pH, except that soil urease activity was very significantly and negatively correlated with soil pH. The results of this research indicated that organic farming is recommended for maintaining soil fertility and plant productivity; however, small use of urea fertilizer is still needed in the farming.

Abstract

Nyamplung shell is a biomass whose existence has not been optimally utilized. Biomass is a solid waste that can be used again as a source of fuel. Favorable characteristics of the biomass is an energy source that can be utilized in a sustainable manner because it is renewable. Biomass of Nyamplung shell can be processed become a form of solid fuel with a same specific dimension, it is resulting from compression of bulk materials, powders, and the relatively small size commonly referred to as charcoal briquettes.  The aim of this research is to test the feasibility of nyamplung shell as a raw material for making briquettes on the households by conducting analysis of quality parameters briquette specimens including physical properties (water content, calor value, and density), briquette durability (persistence press), chemical (ash content, fixed carbon and volatile matter content) and the rate of burning charcoal briquette.  The treatment in this aim is a mixture composition of raw materials (charcoal of Nyamplung shell) who were given the same amount of adhesive and compressed by compressing hydraulic briquette. The results showed that, charcoal briquettes made from the Calophyllum shell can be used as alternative energy, with a characteristic range of values from 3,39-3,83% moisture content, calor value ranges from 3.646,14-5.431,35 calories / gram, the range of density values 0,663-0,721 gram/cm3, the range of persistence press value 1,98-5,39 kg/cm2, the range of ash content value 19,89-24,51%, the range of fixed carbon value 33,09-40,86%, the range of volatile matter value 35,03-38,57%, and the range of rate of burning from 0,0574-0,0898 grams/second. The low value of moisture content can lead to higher heating value of charcoal briquettes. High/low levels of volatile could affect fast/slow rate of burning charcoal briquettes. Key words : nyamplung shell, biomass, charcoal briquette
