Rabbit’s urine waste (RUW) is one of the by-products of rabbit metabolism that not utilized. The complex nutrient content of rabbit’s urine is an enormous potential as a basic ingredient of liquid organic fertilizer (LOF). In the production process of LOF, the fermentation process becomes very important. In the fermentation process, the role of decomposer is very important. The use of commercial decomposers (CD) containing selected microorganisms is difficult to implement in rural areas, as they are expensive and difficult to obtain. Therefore, it is very important to find alternative sources of decomposers derived from nature.  This study aims to evaluate the quality of LOF made from RUW using local microorganism (LM) as a decomposer. A total of 3 types of decomposers are applied, namely: 1) feces extract (FE); 2) banana root extract (RBE) and 3) commercial decomposer (CD) as a control. The fermentation process was done for 4 weeks. As many as 3 types of aeration process time (APT) were applied, namely: 1) 0 h; 2) 48 h and 96 h.  The results showed that the differences of APT resulted in pH values; C-Organic levels and C/N ratio of LOF from LUK were different, whereas N-organic and P205 levels were relatively constant.  Different types of decomposers applied in the fermentation process yield different levels of K2O, but the pH value, C-Organic content, C/N ratio and P205 were relatively constant. Performance of CD in LOF fermentation process was no different from FE and RBE performance. Application of both types of decomposers (FE and RBE)was equally potential to replace CD as a decomposer in the production process of LOF. Implementation of APT for 48 h was the best time process than others.

The aim of the work was to evaluate the effect of addition of humidity absorbent (malt sprouts) and chemical conservation additive on fermentation process quality of brewer grains’ silage. Chemical conservation additive was based on formic acid, propionic acid, benzoic acid and ammonium formate content. In a model experiment the fresh brewer grains were used. A dry matter (DM) content of brewer grains was 187.4 g / kg. Six treatments with three repetitions per treatment were prepared. The treatments A1, A2 and A3 were not supplied by humidity absorbent. Treatment A1 was a control treatment without any additive. The treatments A2 and A3 were supplied by chemical conservation additive in a dose of 3 L per tonne and 6 L per tonne, respectively. The treatments B1, B2 and B3 were supplied by malt sprouts to reach DM content of conserved matter on level 320–350 g / kg. Moreover the treatments B2 and B3 were supplied by chemical additive with its dose 3 and 6 L per tonne. Model silages were evaluated after 8 months of conservation at average laboratory temperature 26–28  °C, from each treatment were the final laboratory samples taken and analyzed. During conservation of treatments B1, B2 and B3 were no drain recognized. From A1 treatment drained 1300 ml of waste fluid that is 145 L per tonne of conserved matter. That was significant (P < 0.01) the malt sprouts addition support the lactic acid production and eliminate acetic acid production. There was no propionic acid or butyric acid detected in silages with malt sprouts event in these silages were analyzed higher (P < 0.01) concentration of ammoniac. Chemical additive supplementation improved (P < 0.01) the pH value and water leach acidity. The results show the malt sprout addition eliminates waste fluid drain and improves fermentation process. The higher concentration of chemical additive (6 l / t) inhibited the fermentation process in our model experiment.

Fermentation is an essential step in obtaining good quality almonds. Thus, the present study aimed to evaluate the fermentation process of cocoa almonds and quantify the physicochemical and microbiological quality of different cocoa blends with the addition of coffee and cardamom, aiming at the reduction of the cost of processing, the addition of value to the raw material, and technological and scientific development of the Amazon region. The experimental design used was completely randomized, arranged in a 4 x 2 x 3 factorial scheme, corresponding to four fermentation times, two fermentation, three concentrations of pulp (blends) (pure cocoa, cocoa + coffee, and cocoa + cardamom), and three replicates. The results made it possible to conclude that the temperature inside the mass measured every 48 hours after turning increased with the fermentation time, reaching its maximum on the seventh day of fermentation. The increase in the temperature inside the fermentation mass on the seventh day is due to the higher concentration of acetic acid, evidenced by the reduction in pH value and consequent reduction in °Brix. Fermentation in a greenhouse at a temperature of 40 °C enables the maintenance of stable temperature throughout the fermentation process for blends of cocoa with the addition of coffee and cardamom. It is verified that, when there is a pre-established temperature, as in a greenhouse at 40 °C, there is a decrease in the values of °Brix and soluble solids present in the final product. Temperature, pH, and sugars are determining factors for the duration of the fermentation process and quality of pure cocoa almonds and cocoa almonds with the addition of coffee and cardamom. Under the experimental conditions, fermentation time from seven days is sufficient to ensure the physicochemical and microbiological quality of cocoa blends with the addition of coffee and cardamom, but it should not exceed nine days.

The Moment

The use of organic fertilizers in agricultural production can not only increase soil fertility but also at the same time improve soil quality. Organic fertilizer is a unique product because it can improve physical properties, chemical, and biological soil as plant growth media. These characteristics bring the organic fertilizers into a valuable product that can be used in a variety of use. Today in Indonesia, there are so many outstanding varieties of organic fertilizer products either refined or imported products. Monitoring of the quality and feasibility of organic fertilizer materials is needed, so they will not harm the farmers as consumers. Each country develops criteria standard of organic fertilizer valuing each country's interest. United States, Canada, Australia and Europe use different compost quality criteria tailored to the needs and environmental rules that apply. So far in Indonesia rules used in determining quality is Permentan No. 02/Pert/HK.060/2/2006 which was then updated with Permentan No.28/PERMENTAN/OT.140/2/2009 on Organic Fertilizers and Soil Ameliorant. Basically, the appraisal made on the maturity and quality of organic fertilizers is based on observation of physical, chemical, and biological parameters. Review of the criteria used in the Regulation of the Minister of Agriculture was necessary in considering the criteria used which are very harmful to consumers, such as if it is satated that C-organic content is approximately 12%, which is low, it means that there might exist some follow-up materials such as glass, plastic in the fertilizer about 2%. If the rules are maintained, it will be very detrimental to Indonesia because of invasion from over seas. Import organic fertilizers would be siege to Indonesian farmers. Permentan No.28/PERMENTAN/SR.130/5/2009 has also set up institutions in charge of monitoring the quality of organic fertilizers. However, the quality control must be carried out. It is not only at the level of the end product, but it must also begin from the moment of the production process by establishing a supervisory agency competent. Since organic fertilizers can be produced by large industries, small and medium-scale farmers, the level of supervision is needed with different approaches.

Abstract Terasi is a fermented product made from shrimp or fish with or without salt. In general shrimp paste producers only add high salt concentration to preserve the raw materials and to ensure successfully fermentation process. However there are shrimp paste producers in the Pati, Central Java, Indonesia that use sucrose sugar as a source of carbohydrate in the shrimp paste production. Sugar will affect the reactions that occur during the shrimp paste production process and will ultimately affect the characteristics of the product. This study aims was to determine whether there is an effect of adding sucrose sugar to the flavor and sensory characteristics of the shrimp paste. The Result showed that the addition of sugar did not affect the aw and TPC BAL value, but it decreased the TVBN value, soften the texture value and in addition the sensory was more prefered by the panelist. The characteristic of shrimp paste with sugar addition was low aw value 0.631 ± 0.631, TPC BAL was not detected, TVBN value 115.641 ± 9.940 mgN/(100 gr) and sensory 7.872 < µ < 8.328. The use of sucrose can be recommended to be added during shrimp paste production to increase consumer preference.

The Minang Bangkit Merbabu Farmer Group use organic materials and produce their own liquid organic fertilizer. This liquid organic fertilizer is made of varied ingredients: rabbit urine, cow's milk, free-range chicken eggs, palm sugar, coconut water, pineapple, shrimp paste, bamboo roots, ginger, and turmeric. Composting is strongly affected by pH and aeration method. Liquid organic fertilizer made by farmers usually have an initial pH of around 3.7. This mixture was usually composted using semi-anaerobic method. Through this study, we wanted to find out whether different methods of aeration and addition of rabbit urine would result in different liquid organic fertilizer quality. The quality of liquid organic fertilizer includes C-organic, total nitrogen, total phosphorus and total potassium. The experiment was designed as a factorial randomized block design. There were 2 factors tested: rabbit urine volume and aeration method. There were two levels of rabbit urine volume : original and modified ones. There were three levels of aeration method: aerobic, semi-anaerobic, and anaerobic. In total, there were six treatments and four replication for each treatment. The results of the analysis showed that composting with the aerobic method at the original rabbit urine volume could increase the concentration of nutrient content so that it gave the highest yield. It is different from composting at a modified rabbit urine volume, because the highest yield is in the anaerobic method. Keywords: aerated, organic, rabbit urine volume
