Abstract

Sari. Trichoderma spp merupakan golongan fungi yang bersifat antipatogen, khususnya layu kecambah, sedangkan bokashi merupakan kompos yang diperkaya dengan beberapa mikroba yang bermanfaat bagi pertumbuhan tanaman.Tulisan ini merupakan rangkuman penelitian pot menggunakan kompos Trichoderma spp sebagai pelapis benih terdeteriorasi disertai bokashi kotoran hewan yang dilakukan pada tanah lahan kering dan tanah sawah pada tahun 2014 dan 2017. Percobaan pertama membandingkan efektivitas beberapa agen hayati sebagai pelapis benih pengaruhnya terhadap vigor benih dan hasil tanaman. Hasil percobaan menunjukkan penggunaan kompos Trichoderma hasilnya lebih baik dibandingkan agen hayati lainnya. Hasil percobaan selanjutnya menunjukkan  bahwa pelapisan benih dengan 1 sampai 3 g  kompos Trichoderma spp per 100 butir benih pengaruhnya tidak nyata dibandingkan dengan penggunaan pelapis benih berupa pestisida, baik terhadap vigor  maupun hasil biji per tanaman. Pemberian bokashi sebaliknya secara nyata mampu meningkatkan hasil biji per tanaman . Pemberian bokashi 15 t ha-1menghasilkan biji seberat 19.83 g per tanaman  atau setara dengan 2,379 t ha-1 atau 27,3 % lebih tinggi dari kontrol.Kata kunci : Benih terdeteriorasi, pelapisan benih, Trichoderma, Bokashi Abstract. Trichoderma spp is a group of antipatogenic fungi, especially seedling wilted, while bokashi is a compost enriched with some microbes that are beneficial to plant growth. This paper is a compilation of pot experiment using Trichoderma compost for coating deteriorated seed and accompanied by bokashi on dry land soil and paddy soil in 2014 and 2017 respectively. The first experiment compares the effectiveness of several biological agents as a seed coating of its effect on seed vigor and yield. The results of first experiment showed that the use of 2 g Trichoderma compost 100 seeds-1 was better than other biological agents. However between 1.2 and 3 g of Trichoderma compost per 100 seeds was not significant effect on seed vigor and yield. The results of experiment showed that the coating of seeds with 1 – 3 g of Trichoderma spp compost 100 compared with pesticide seed coatings. Increased of yield only affected bokashi application.

Abstract

Processing of gold ore at artisanal gold mining in Kertajaya Village, Sukabumi, West Java produces residual processing waste or tailings which are generally disposed of into rivers or farm, stored in storage ponds or put in sacks for reprocessing. Due to the limited land owned by the community, the ponds and farm that were formerly dumped for tailings are widely used for farming. This study aims to determine the effect of adding topsoil and compost dose on the growth of sweet potato (Ipomoea batatas) at the maximum vegetative phase (7 Weeks after planted). The topsoil used in this study was taken from Kertajaya Village, which is an inceptisol soil type, while the sweet potato plant used was sweet potato clone MZ119. The research was conducted at the Ciparanje Experimental Farm, Faculty of Agriculture UNPAD, Sumedang from January to May 2020. This experiment used a factorial randomized block design with two factors, namely the topsoil-tailing ratio of 3 levels (30% w/w; 50% w/w; and 70% w/w) and compost doses of 4 levels (without compost (control); 10 tonnes ha-1; 20 tonnes ha-1; and 30 tonnes ha-1) with 3 replications. The results showed that the combination treatment of 70% topsoil: 30% tailings and compost dosage of 30 tonnes ha-1 could increase the length of sweet potato vein in the maximum vegetative phase which was 24.33 cm and the number of leaves was 54.33.

Abstract

Hydroponic system is an alternative agricultural cultivation technology and a potential system to overcome the decreasing availability of land. Tomato production with this system has its own market segment. Balanced nutrient management combined with inoculation of functional microbial consortium (N-fixing bacteria and phosphate solubilizers) is one of the efforts to increase tomato production in a hydroponic system. This experiment aimed to examine the effect of microbial consortium and hydroponic nutrition on tomato plant growth, Azotobacter spp. population, N uptake and tomato yield. The research design used was a factorial randomized block design (RBD) consisted of two factors. The first factor was the dose of the microbial consortium, consisting of three levels (0 mL/polybag, 5 mL/polybag, and 10 mL/polybag. The second factor was the nutritional dose consisting of three levels (0 mL, 250 mL, and 500 mL). The experimental results showed that there was no interaction between the microbial consortium treatment nutrients on hydroponic plants’ height, N uptake, Azotobacter spp. population and tomato yield. Increased nutrient dose significantly increased N uptake, with the highest yield at 500 ml/pot. But the increased nutrients dose did not lead to significantly different tomato yields. Inoculation of the microbial consortium did not significantly increase all tested parameters.

Abstract

Inorganic fertilizer is a very important agricultural input to increase agricultural production. Uncalculated and continuous application of inorganic fertilizers will lead to the reduction of soil fertility and degradation of environmental quality. Therefore, a strategy is needed to support the environmental sustainability in agriculture. One of the efforts is through the production of biofertilizer and organic fertilizer from local resources. Organic fertilizer for rice plants can be made by utilizing the local water fern, Azolla pinnata. A. pinnata can be applied on rice fields as green manure by directly placing it into the soil or spread on the surface of rice fields. Organic fertilizer that made from Azolla will be more advantageous because it can be applied with biofertilizer. This study aimed to determine the formulation of Azolla based solid biofertilizer that can support the growth of functional microbial population based on the Agriculture Ministry (Permentan) standard number 70/2011. The design of the study method used was Completely Randomized Design with six replications. The treatments used were inoculant starter with 3% molasses, 3% molasses + 10% rice wash water, 3% molasses + 1% yeast extract, and 3% molasses + 10% rice wash water + 1% yeast extract. The results of this study showed that Azolla-based solids fertilizer with starter formula 3% inoculant molasses + 10% rice water + 1% yeast extract have the population of Azotobacter, Azospirillum, endophytic bacteria and phosphate solubilizing microbe were greater than 108 cfu/g dry weight. Functional microbial of solids fertilizers in all formulas used do not show the difference on inhabiting in the N-free media or Pikovskaya selective media.  Keywords: Azolla pinnata, formulation, biofertilizer, organic fertilize

Abstract

Bioremediation of petroleum waste using the land treatment system is generally carried out by indigenous Petrophilic stimulation as a degrading agent. One of the efforts to improve the performance of the bioremediation system is by adding petrophilic inoculants and organic material as a source of nutrition. This experiment focused on observation of the effect of endogenous petrophilic consortium by adding chicken manure compost towards bioremediation performance parameters, including the efficiency of hydrocarbon degradation, soil pH and petrobacter population on Jatinangor Inceptisols contaminated with petroleum waste. The experiment Design used in this experiment was Factorial Randomized Block Design (FRBD). The first factor was the variation of the concentration  of the petrophilic consortium, consisted of: (i) without a petrophilic consortium, (ii) the concentration of petrophilic consortium 1% (w/ w), (iii) the concentration of petrophilic consortium 3% (w/ w ), (iv) concentration of petrophilic consortium 5% (w/ w). The second factor was the variation of the concentration of chicken manure compost: (ii) without compost chicken manure, (ii) the concentration of chicken manure compost 1.5% (w / w), and (iii) the concentration of chicken manure compost 3% (w/w). ). The results showed that the treatment of exogenous Petrophilic and chicken manure could not significantly improve the biodegradation efficiency of hydrocarbons, but the Petrophilic additives of 3% (w/ w) could increase the highest Petrophilic population. From this study was found that indigenous petrophilic had the potential to degrade hydrocarbons by 71.20%, while the application of exogenous 1% (w/w) petrophilic was able to degrade hydrocarbons by 71.97 %.

Abstract

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, in order to fulfill the continuous increase, researches were conducted to increase land productivity. The increase of growth and productivity of upland rice with the application of Azospirillum sp. and Azotobacter sp. in compost, Azolla, and rice bran carrier were studied. Nitrogen fixer were applied as a biofertiliser as a mean to supply available nitrogen for upland rice growth. This research was conducted in Ciparanje Experimental Field and Soil Biology Laboratory, Faculty of Agriculture, Universitas Padjadjaran. In this research, Randomized Block Design was used to analyze two factors: urea dose (100% and 50%) and Nfixer bacteria in various carriers (individual carrier and combination of liquid inoculant, green compost, Azolla compost, rice bran). The result showed an interaction between two factors towards the grain weight of upland rice. The application of 100% urea dose showed higher result compared to 50% urea dose on grain weight. N fixer bacteria combined with compost, Azolla, and rice bran carrier gave the highest result on the number of tillers, chlorophyll content, and grain weight.

Abstract

Acid mine drainage (AMD) is a waste product from coal mining process. Acidic waste will impose a serious environmental issue such as organism annihilation and destruction of environmental ecosystem. Proper AMD management is required in order to restore polluted water to the proper standard condition. The Constructed Wetland system with Akar Wangi (Vetiveria zizanioides L.) and various organic growth medium compositions and sulphate-reducing bacteria and the composition of the media for several types of organic matter with sulfate-reducing bacteria (SRB) inoculation as stimulant was deemed a promising solution. This study was designed in randomized block design (RBD) consisted of nine treatments with three replicates. The treatments were: (A) = without organic matter and without SRB inoculation (control), (B) = 100% compost, (C) = 100% sawdust, (D) = 50% compost + 50% sawdust, (E ) = no organic matter + SRB inoculation (105 MPN ml-1), (F) = 100% compost + SRB inoculation, (G) = 100% sawdust + SRB inoculation, H = 50% compost + 50% sawdust + SRB inoculation, I = 75% compost + 25% sawdust + SRB inoculation. Results showed that 100% compost and SRB application increased polluted water pH. Application of 100% sawdust with or without SRB inoculation gave the highest reduction in sulfate content. SRB also has the potential to increase the height of Akar Wangi plant.
