ABSTRACT        The production of pig manure waste potentially pollutes the soil, water and air. One of the most effective processing a waste treatments is through composting. The composting process takes a long time if not assisted by the activator as decomposers of organic materials in order to accelerate the composting process. Activators such as local microorganism (MOL) contain macro nutrients, micro and active microorganism that potentially decomposed organic materials, growth stimulants and pest/disease control agents such as to help speed up the composting process. This study aims to determine the C/N ratio of optimal raw materials for composting of pig manure and vegetable waste, determining the effect of adding local microorganism (MOL) to the length of time of composting and determining the effectiveness of business from composting of pig manure and vegetable waste based on the calculation of B/C ratio.        This research uses quantitative approach with experiment method. The first stage is the preparation of the raw material which is divided into three groups : composition 1 with 75% (pig manure) and 25% (vegetable waste), composition 2 with 50% (pig manure) and 50% (vegetable waste) and then composition 3 with 25% (pig manure) and 75% (vegetable waste). Furthermore, the best raw material composition was treated with variations of MOL addition of A (100 ml), B (300 ml), C (500 ml) and D (without MOL).        The results showed that the composition of the best raw material mixture was a mixture composition of 25% (pig manure) and 75% (vegetable waste) with a C/N ratio of 38.95. The effect of MOL addition indicates that the greater MOL volume the faster to composting process. The quality compost with addition of MOL has C/N ratio levels is (16,30), N-total (1,65%), P tersedia (8043,02 ppm), K tersedia (8857,40 ppm), Fe (1,87%), Mn (0,09%) Zn (480 ppm) in which that value meets the SNI 19-7030-2004. Based on analysis of B/C ratio obtained result of 1.04 where the value is approaching criteria B/C ratio more than 1.00 which means compost business feasible to be developed.   Keywords : Pig manure, MOL, time of composting, composter, B/C ratio

Organic materials that are generally used as raw material for organic fertilizer granules (POG) is a natural organic material that has been degrade, smooth and dry. One of the main raw materials are always used with a very high percentage of usage, is manure. Manure potential in Indonesia is very high, amounting to 113.6 million tons per year, or 64.7 million tons per year to the island of Java. From this amount, it will be generated numbers POG production potential of 17.5 million tons per year (total Indonesia) or 9.9 million tons per year for the island of Java. While the realistic POG production predictions figures made from raw manure is 2.5 million tons annually, a figure that has been unable to meet the number requirement of POG greater than 4 million tons per year. Therefore, in producing POG, it should be to maximize the using of the potential of other organic materials so that the use of manure can be saved. With the use of a small amount of manure (maximum 30% for cow manure), it would be useful also to avoid the production of POG with high Fe content.keywods: organic material, manure, granule organic fertilizer

The development of information technology has become a necessity for every company, one of which is the optimization of inventory planning. The joint warehouse owned by the Chickenpedia Restaurant which has to supply various types of raw materials to the three restaurant branches often experiences stock outs and has to make emergency orders resulting in losses. For this reason, it is necessary to control the inventory of raw materials in the shared warehouse so that stock outs can be overcome and losses that arise can be minimized. One of them is by using the Continuous Review method. By using this method, the optimal order quantity and reorder point will be obtained. The weakness is iterative calculation and monitoring of raw material stock manually. For this reason, it is necessary to support an information system to speed up and make it easier to calculate when to place an order and how many orders of raw materials to suppliers so as to reduce the occurrence of running out of raw materials. The Information System can also monitor the stock of raw materials every day in real time based on the number of incoming and outgoing goods that enter the application.

Management of post-production wood waste in the aspect of circular economy. Sustainable resource management involves turning waste into resources. The estimation of various waste streams and their potential use as secondary raw materials underlies the circular economy. The management of wood waste in terms of the Circular Economy should assume material use of this waste before energy use. One of the possibilities of material management of this waste is the use of biological treatment through composting. Input materials for the composting process should have technological and physical-chemical characteristics, respectively. The aim of this study was to characterize the wood raw material (wood waste as a by-product) and qualify it for the composting process on the basis of its composition. Based on the literature research, it was found that there is possibility of using these wastes for management through biological disposal. The obtained composts from wood waste can be used as a raw material to supply the soil with humic substances and mineral compounds.

Drying has an enormous impact on the quality of final masonry clay elements. The accumulated knowledge about modeling the drying process, as well as the registered progress in computing the coupling between the heat and mass transfer during the last decade has reached the applicative industrial level. The available novel commercial drying solutions have dropped the drying cycle to 5 hours for hollow clay products and up to 9 hours for clay blocks of large size and weight. The ability to speed up the drying process also strongly depends on the properties of the raw materials. The decision on optimization of the existing dryer and its upgrade or investment in a novel drying facility must be experimentally validated. Results of the one-month monitoring and analysis of the production process in one Serbian brick factory including the material and energy balances are given in this paper. Based on the collected data, raw material limitations and costs of the novel dryer the existing tunnel dryer upgrade and the minimization of the "false" ambient air into the dryer are proposed.

Abstract Organic waste has the potency to use as bio activator material. This research compares household organic waste compost results with the addition of bio activator from local microorganism activator (LMO) from tuna fish and shrimp waste with Effective Microorganisms (EM4). The composting method used is aerobic composting with the Takakura composting technique. This composting is carried out in 5 variations, variation one without-bio activator added, 2 with LMO of tuna fish waste added, variation 3 with LMO shrimp waste added, variation 4 with LMO of tuna fish, and shrimp waste added, variation 5 with EM4 added. Analysis of all compost quality has met SNI 19-7030-2004 standards. A total of 2 kg of raw material produced solid compost becomes 0.7-1 kg of compost. The use of bio activators can speed up the composting process to 8-12 days. The variation of adding LMO tuna fish waste was chosen as a suitable alternative compared to other variations. The composting process with LMO of tuna fish waste results from the fastest composting time of 9 days with a C/N ratio of 18.45%, P2O5 0.56 %, and 0.76% K2O, with 0.85 kg of compost. Scoring results in variation 2 is the best variation in compost maturity quality.

The fruits of wild rose (Fructus Rosae) have been widely used in both traditional and officinal medicine for the long time. The pharmacological effect of the Rosehip medicine is related to the content of such biologically active compounds as: water-soluble (ascorbic acid) and fat-soluble (carotenoids) vitamins, as well as flavonoids (astragalin, isoquercitrin, tiliroside). Such medicine as Holosas, Carotolin and Rosehip syrup are obtained from the fruits of this plant. In addition, wild rose fruits are part of the various fees from which patients could prepare water infusions at home themselves. Regulatory documentation provides for the analysis of Rosehip raw materials three parameters: the content of ascorbic acid, the total carotenoids and flavonoids. The quantitative content of the total carotenoids in the fruits of the rosehip is regulated for the production of rosehip oil and Carotolin. However, in our opinion, the method of quantitative determination of the total carotenoids, described in the State Pharmacopoeia of the Russian Federation of the XIV edition, is too complicated and contains an unreasonably entered coefficient in the formula, leading to an overestimation of the analysis results in 10 times. We have developed the methodic of quantitative determination of the total carotenoids in Rosehip, that include single extraction of raw materials with hexane at room temperature and periodic mixing in the ratio of «raw material : extract» 1 : 30. Investigated solution there was obtained by diluting the hexane extract in the ratio of 2:25 and measured the optical density at wavelength 450 nm. Adjustments have been made to the formula for the calculating of the total carotenoids relating to the removal of the coefficient 10 unjustifiably entered into the pharmacopoeial methodic. It was determined that the content of the total carotenoids calculated on ß-carotene varied from 10.15 to 74.5 mg%. The metrological characteristics of the methodic indicate that the error of a single determination of the total carotenoids in the rosehip fruits with a 95% confidence level is ± 3.57%. Based on the results of the studies, a new test quality indicators “content of the total carotenoids at least 30 mg%” was substantiated instead of 300 mg%.
