Tofu liquid waste can be further processed to produce some useful product. That can be kept anaerobically to produce some organic acid. The purpose of this study to know the microbial growth behavior characteristic of liquid tofu waste which produce with different production process, such as specific growth rate (m), doubling time (td), multiplication degree (n), product yield, and efficiency of acetic acid production. This study is also aimed to identify the acid type which produce with different production tofu process. The liquid waste which used for this study is obtained from tofu producer which uses acetic acid and calcium sulfate to coagulate the tofu protein. Liquid tofu waste was incubated 24 hour, in ambient temperature(30oC). analysis of total cell count, glucose concentration, acetic acid concentration, and pH value was evaluated in certain interval, such 0, 2, 4, 6 8, 10, 12, 14 16, 18, 20, 22, 24 hour. Acid type identification was evaluated in some phase during fermentation process. The observation result was plotted into a graphic which was shown the relationship of total cell count, with glucose concentration, acetic acid concentration, and also fermentation time. From the analysis of observation result, It can be concluded that, the specific growth rate of liquid tofu waste with acetic acid as protein coagulator is 0,3015/hour, while the specific growth rate of liquid tofu waste with calcium sulfate as protein coagulator is 0,2174/hour. The doubling time of liquid tofu waste with acetic acid as protein coagulator are 2,2991 hours, while the doubling time of liquid tofu waste with calcium sulfate as protein coagulator are 3,1877 hours. The multiplication degree of liquid tofu waste with acetic acid as protein coagulator are 2,605 times, while the multiplication degree of liquid tofu waste with calcium sulfate as protein coagulator are 1,880 times. The growth yield constant (Y p/s) of liquid tofu waste with acetic acid and calcium sulfate as protein coagulator respectively 8,1 x 109 cfu/mg and 8,1 x 107 cfu/mg. The product yield constant (Y p/s) of liquid tofu waste with acetic acid and calcium sulfate as protein coagulator respectively 1,7237 and 0,0306. The efficiency of acetic acid production during fermentation of liquid tofu waste with acetic acid and calcium sulfate as protein coagulator respectively 15,1376% and 2,5699%.

One of problems faced by farmers in the rice cultivation with organic system is organic fertilizer limited, especially for farmers who do not have livestock. Azolla is one of materials that can be used as organic fertilizer. The aim of the research was to determine whether Azolla (Azolla mycrophylla L.) is able to meet the nutrient needs of some rice varieties on organic rice cultivation. The experiment used factorial complete randomized block design with three factors and three replications. Azolla was spread at days after transplanting and at 25 days after transplanting, 75% of Azolla was incorporated into soil and the rest was left up until rice were harvested. Meanwhile, cow manure was distributed after tillage. The treatment consisted of rice varieties (Mira1, Mentik Wangi and Red and White), Azolla (0 and 2 tons / ha) and manure (0 and 10 tons / ha). The result showed that Azolla did not significantly increase growth and yield of rice, despite it could increase the N uptake 5,4% and P uptake P 17,3% , weight of dry straw, dry grain and 1,000 seeds by 5,86%, 12.7%, 7.37% than without Azolla respectively. Azolla 2 tons/ha with manure 10 tons/ha were able to increase N uptake by 7.6%, the uptake P by 13.7% and the of productive tiller number by 9.88%. From the standpoint of crop yields with organic system, a single use of Azolla has not been able to replace manure.

Catfish farming is strongly influenced by the high price of feed, while azolla is a water fern that has a high nutritional value, can develop quickly and preferably by catfish as feed. The research aims to obtain the most appropriate combination treatment of Azolla inoculum dose and catfish seed size in dual system Azolla - catfish, which is able to provide the highest catfish yield. The experiments were performed in catfish ponds in completely randomized design (CRD) two factors, i,e azolla inoculum doses (250, 500 and 750 gm-1) and head circumference size of catfish seed (3, 4 and 5 cm). Dose of catfish seed is 2,000 head / m2. Variables observed were azolla fresh weight and catfish fresh weight at harvest. Azolla inoculum and catfish seed deployed together in catfish ponds and feeding with concentrate feed for one month. Azolla and catfish harvesting is done on the same day using a sieve. Once drained, Azolla and catfish were weighed separately to determine the severity. Data were analyzed by F test at the level of 95%, followed by Duncan's multiple range test (DMRT) if any significance influence. The results showed that the higher the azolla inoculum number, the higher azolla yield. The larger the size of catfish seed the higher catfish consumption to Azolla. Catfish seed size more than 4 cm will cause an imbalance between the speed of consumption of Azolla by the catfish and the azolla growth rate, so that Azolla be devoured by catfish.

Malnutrition is still one of the big problems the majority of developing countries including Indonesia. Malnutrition is the result of insufficient intake of available nutrients in the human diet. The availability of nutrients is mainly determined by the output of food produced from agricultural systems. Plants provide almost all the necessary vitamins and minerals, but due to low mineral content in staple crops, resulting in the intake becomes less and lead to malnutrition or lack of nutrients. Unfortunately, as a result of population pressure, a lot of the current global food system does not provide enough micronutrients to ensure adequate micronutrient intake for everyone. This has resulted in an increase in the prevalence of micro-nutrient deficiencies (for example, iron deficiency, vitamin A deficiency, and iodine), which now afflicts many poor women resources, infants and children in developing countries. To get a balanced nutrition and adequate then improve the quality of agriculture as a food ingredient indispensable. Various attempts to overcome nutritional deficiencies especially regarding micro nutrient deficiencies, such as supplementation, food fortification and diversification of the food has a lot to do, but did not provide maximum results. Another alternative approach to address the problem of shortage of micronutrients is biofortification, genetic biofortification or agronomic biofortification. This approach emerged due to health and human well-being depends entirely on the plants, either directly or indirectly.

This study aimed to analyze the value chain mapping, governance, improvement of value chain and marketing margins cassava in Pati regency. The basic method used descriptive analytical research. The method of determining the location of the research method and the purposive sampling method is done by snowball sampling with 18 respondents. The results showed there are three models of the value chain by five actors, namely farmers, penebas, grinders, realtor, and collectors flour. Value-added activities conducted on cassava farmers, grinders and collectors. While penebas and brokers act as a liaison between value chain actors. Governance cassava value chain is analyzed through three approaches namely coordination structures, rules and regulations, and provider of information and services. The increase in the value chain are identified in several aspects of increase of processes, products, and functions. Enhanced functions effectively needs to be done because it will produce a positive impact on the actors of the value chain. Grinder has a marketing margin of RP 3300 / kg, meaning that most large margin than other players because it has many activities ranging from wet to cassava starch that have added value. While the perpetrators of broker only has a margin of RP 20 / kg for his activities only as an intermediary without any added value from the starch itself.
