Agricultural waste is rich in cellulosic material that is difficult to degrade but can be decomposed by cellulase enzymes. Cellulosic material is an organic component abundantly in nature in the form of cellulose and hemicellulose polymer. Utilization of microbes in the process of waste bioconversion can be done to get added value from the waste material into other products such as organic fertilizer. Cellulase-producing microbes can be isolated from various sources, one of which is from termite nests. The use of microbes from termite nests as decomposers for composting high-yielding agricultural waste was carried out in this study. Cellulolytic microbial isolates (combination of bacteria and fungi and without decomposers) were applied to agricultural wastes high in cellulose content: rice straw, bagasse, and oil palm empty fruit bunches. Randomized Block Design was applied and each treatment was and repeated 3 times. The composting process was carried out for 1 month indoors. The results showed that cellulolytic microbial consortium obtained from termite nests reduced the compost cellulose content of bagasse agricultural waste in one month. Whereas rice straw and oil palm empty fruit bunches showed a tendency to decrease cellulose content because cellulose degradation by decomposer microbes still continues after one month of incubation.

ABSTRACT Organic farming, especially organic rice requires a continuing supply of organic fertilizer in large quantity as a source of nutrition for rice plants. In long-run, organic system is can retain higher soil organic carbon (SOC), partially compensates the negative impact by improving physical and biological properties, as well as nutrient retention capacity of the soil. Azolla pinnata is an organic nitrogen source rich in protein. The high nitrogen content in A. pinnata is related to the presence of nitrogen-fixing Anabaena azollae microsimbion in A. pinnata leaves. A. pinnata compost is an alternative for biofertilizer carrier that can be used in organic rice fields. The contribution of azolla-based organic farming for organic farmers is to decrease the dependency on the animal manure in cropping season. The field experiment comprised of conventional compost as control and combination of organic fertilizer and biofertilizer with Azolla carrier. Organic fertilizer were 5 ton/hectare (ton/ha), 7.5 ton/ha, and 10 ton/ha combined with 0, 10, 20 kg/ha biofertilizer with Azolla carrier with no addition of inorganic fertilizer. Complete randomized design were used in the experiment which consisted of three replications. This technology produced organic fertilizer better than conventional compost of rice straw and manure made by farmers. Organic fertilizer base with Azolla mixture of 7.5 ton ha-1 plus solid biofertilizer (10 kg/ha) can produce 6.58 ton/ha of dry harvested grain, higher than conventional compost treatment (control). The application of organic fertilizer base on azolla and solid biofertilizers gave the increasing yield prospect of organic rice in Cisayong, Tasikmalaya regency West Java.Keywords : Azolla pinata, carbon, nitrogen, organic farming, rice.

This study was conducted to determine the effect of Azolla pinnata and biofertilizers (Azotobacter and Phosphate Solubilizing Bacteria) on the total microflora, microfauna, organic C, N-total soil, and C/N ratio of soil in lowland rice. The study was carried out in the SPLPP experimental field (Agricultural Research and Development Research Studio) of the Faculty of Agriculture, Padjadjaran University, Jelekong Village, Ciparay, Bandung Regency, West Java, with an altitude of 628 meters above the sea level. The experimental design used was factorial randomized block design consisted of two factors and repeated four times. The first factor was the provision of Azolla with two levels: without Azolla and 3 tons ha-1 of Azolla pinnata. The second factor was the provision of biofertilizer with three levels, without biofertilizer, 5 L ha-1 biofertilizer, and 10 L ha-1 biofertilizer. The results showed that there was an interaction between A. pinnata with biofertilizer on the increase in the total bacterial population. Total fungus, microfauna (nematodes), and soils N-total content did not increase with the addition of Azolla or biofertilizers. Independently A. pinnata increased soil C-organic matter while biofertilizer 10 L ha-1 increased the total population of actinomycetes.

Azospirillium is a genus of non-symbiotic N fixer bacteria, known as a biological fertilizer inoculant. The quality of Azospirillum sp. inoculant often decrease when applied outside its original habitat. Therefore, it is necessary to maintain the viability and increase its effectiveness. One way that can be done is by adding organic material as additives as a source of energy for bacteria. Potential organic materials can be used as additives to stimulate the viability, activity and effectiveness of Azospirillium sp. are coconut water, molasses and bran. The organic material contained elements such as C, N and P as the source of nutrients for Azospirillium sp. which was inoculated in Soybean (Glycine max L.) plants. This experiment aimed to examine the effect of additive application on Azospirillum sp. population, root nodules, and seed weight of soybean plants (Glycine max L.) on Jatinangor Inceptisols. The experimental design used was Randomized Block Design (RBD) consisted of combination between of Azospirillum sp. and additives type, namely molasses, coconut water and bran. The results showed that the application of a mixture of bran, molasses, and coconut water attracted the population of Azospirillum sp. higher than the control treatments. Meanwhile molasses, coconut water, and additive mixtures have the potential to increase the number of root nodules and soybean pods yields. Coconut water, molasses and bran are organic materials that have the potential as additives that stimulate the activity and increase the population of Azospirillium sp. and soybean pods.

Corn cultivation on Ultisols is limited due to low nitrogen content of the soil. Efforts to increase the N content in the soil include the use of biofertilizers by symbiotic nitrogen-fixing endophytic bacteria. This study assesed various combination of nitrogen fertilizer doses and N2-fixing endophytic biofertilizer to increase the growth of maize in Ultisols Kentrong. The experiment was conducted at the Ciparanje Experimental Greenhouse, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor. A randomized block design was used which consisted of 16 treatments with 3 replications, with a combination of doses of urea fertilizer and endophytic biofertilizer applied to seeds or planting holes. The experimental results showed that the combination of urea fertilizer and biofertilizer doses had a significant effect on the population of endophytic bacteria in the roots and leaves of corn plants, plant wet weight, root dry weight and shoot dry weight, plant height, stem diameter, plant nitrogen uptake and content of plants but was not significantly affected on the number of corn leaves. Combination of 80 kg ha-1 urea fertilizer and 3.6 kg ha-1 of biofertilizer was the best combination which increased the dry weight of the corn plant and reduced the dose of urea fertilizer

The concept of balanced fertilization application is appropriate for tomato plant cultivation. However, most farmers still apply inorganic fertilizers excessively, which negatively impacts the environment and plant productivity. Alternative efforts can be made to reduce the usage for inorganic fertilizers through effective plant growth-promoting rhizobacteria (PGPR) application. This research studied the characteristics of the PGPR inoculants effectiveness (Azotobacter sp. and Pseudomonassp.) combined with NPK towards tomato in Lembang Andisol. The experimental design used was randomized block design, with three replications: A (Control), B (1 PGPR + 0 NPK), C (1 PGPR + NPK), D (1 PGPR + NPK), E (1 PGPR + NPK), F (1 PGPR + 1 NPK), G (1 PGPR + 1 NPK), H (2 PGPR + 1 NPK), I (0 PGPR + 1 NPK), J (½ PGPR +1 NPK). The results showed the treatments of C, F, and J resulted in higher total soil N content than the control treatment. Meanwhile, C and D treatment increased plant N uptake compared to control. Nitrogen uptake increased with the decrease of NPK dose application. All of the PGPR inoculation treatments with NPK combination did not increase Azotobacter sp. population and tomato yield. The yield of tomatoes per hectare showed that the PGPR inoculation at a dose of 3 l/ha (1 PGPR + NPK) increased yield by 28.7% compared to 1 NPK (150 kg/ha of Urea, 100 kg SP-36 and 50 kg/ha KCl) dose. Application of 3 l/ha of PGPR inoculant can save up to 75% of NPK usage

Indonesia is one of the largest coconut (Coconus nucifera L.) producing country in the world. Cocopeat can be mixed with chicken manure because of its relatively higher nutrient content compared to other manures. Cocopeat and chicken manure mixture can be an alternative to soilless planting media to support sustainable agriculture. In this study, the chemical and biological characters of cocopeat and chicken manure mixture were analyzed. Five different of combinations of cocopeat and chicken manure mixture: A (1: 1), B (2: 1), C (1: 2), D (2: 3), E (3: 2) were used as treatment. A Completely Randomize Design (CRD) with two replications were used. Data were analyzed with Independent T-test methods. The lowest C/N (33,39) was from D treatment (2:3), highest P2O5 content (0,08%) by C treatment (2:1), highest K2O content (0,03%) from A treatment (1:1) as control, the highest Ca-dd content (31,3%) was E treatment (3:2), and the highest Mg-dd content (1,45%) was obtained from control. All treatments reached the minimum moisture content limit for planting media. The total number of highest bacteria (161 x 107 cfu/g) is showed by D treatment (2:3), and the highest fungi level (58 x104 cfu/g) shown by C treatment (2:1).

Inceptisols are soils that have problems with fertility. Inorganic P fertilizer is a quick choice to restore nutrient availability for plants, but long-term use may harm soil and plants. Another alternative to this problem by using a biofertilizer. Biofertilizer contains microbes that can promote plant growth by increasing the supply of nutrients through their biological activities in the soil. Some microbes are known to have to dissolve phosphate ability through secretion of organic acids and enzymes mechanism. This experiment was conducted to examine the effect of hydrogel-based biofertilizer combined with inorganic P fertilizer (SP-36) on the growth and maize yields on Inceptisols Jatinangor. The biofertilizers were a consortium of phosphate solubilizing microbes (PSM) consisting of Bacillus subtilis, Pseudomonas mallei, Burkholderia cepacia, and Trichoderma asperellum. The pot experiment using a Randomized Block Design (RBD) consisted of 9 treatments with 3 replications. The treatments consisted of control, recommended dose of inorganic P fertilizer (100 kg Ha-1), biofertilizer dose of 50 kg Ha-1, and a combination of biofertilizer and inorganic P fertilizer. The results showed that the combination of ½ dose of hydrogel-based biofertilizer and ¾ dose of P fertilizer increased maize yield. In addition, the application of biofertilizer can reduce inorganic P fertilizer needs up to ¾ recommended dose.

The fruitfulness of biofertilizer application in increasing plant growth and yield is when the formulation uses selected microbial isolates that do not cause disease to plants. Hypersensitivity test is carried out to ensure that the microbial isolates used in the formulation of biofertilizer are not pathogenic to plants. The purpose of this study was to determine the pathogenicity of three selected potassium solubilizing bacteria (KSB) isolates (BPK-DHJ3-3150[17], BPK-DHJ1-4125[2], and BPKDHJ2-5250[16]) isolated from the maize plant rhizosphere on Inceptisols Jatinangor. The research was conducted using a qualitative experimental method that obtained data in the form of visual photos. The three selected KSB isolates were inoculated on tobacco leaves and observed for necrosis symptoms. The experimental results showed that the three selected KSB isolates did not cause a positive hypersensitivity reaction in tobacco leaves, which was indicated by the absence of necrosis symptoms at the leaf location where the KSB isolates were inoculated. The three KSB isolates were nonpathogenic isolates to plants.

The low productivity of cucumber plants in Indonesia can be caused by several factors, one of which is fertilization. Fertilization on Inceptisol soil which has a low nitrogen content is needed to increase cucumber crop yields. The use of inorganic fertilizers is limited to avoid environmental pollution, so the use of biofertilizers can be an environmentally friendly option. The purpose of this study was to determine the effect of concentration and interval application of azolla extract based biofertilizer on the total soil N, plant N content, Azotobacter population and cucumber yield. The experiment was carried out from August to November 2021 at the Ciparanje Experimental Garden, Faculty of Agriculture, Padjadjaran University. This experiment used a Completely Randomized Block Design of a combination concentrations (0, 5, 10, 15, 20 mL.L-1) and time of application (1, 2, 3 times). The results showed that the application of azolla extract based biofertilizer with different concentrations and application times had a significant effect on the azotobacter population but had no significant effect on soil nitrogen levels, plant nitrogen concentrations, and cucumber yields. The addition of 20 mL/L 2 times application of azolla-based biofertilizer increased cucumber fruit weight by 35.97% compared to control but did not cause a significant increase in yield
