Abstract : This study was conducted to evaluate physical, chemical and performance of selected commercial layer feeds and self-formulated diet on growth performance, percentage hen day production, egg production performance and egg qualities. A total of 1,200 pullet birds, Isa Brown breed of 18- weeks old were used for this study which were replicated five times, in a completely randomize design, this experiment lasted for twelve weeks. All feeds were in mash form except one-layer feed in crumbled form. There were also statistical variations in crude protein, crude fat, crude fibre contents and ash content of the various feeds as analyzed. Significant differences (p<0.05) were observed in final body weight and weight gain with FF diet having the highest performance and VF having the least performance, hens fed with VF has the highest feed intake and least was observed in hens fed FF diet. Feed conversion ratio and percentage hen day production were significantly different across the treatments. Total number of eggs laid was significantly different among treatments. Significant differences (p<0.05) was observed in egg qualities at 30 and 32 weeks of age but only yolk colour was different significantly (p<0.05) at 28weeks of age. It was concluded that self-formulated diet (FF) found to be most economical among the whole experimental diets and has the highest performance..

Abstract : This study examines the integration of the rice market between Indonesia as a rice importing country and Thailand-Vietnam as a rice exporting country within the ASEAN region. The data used in this study were monthly data on rice prices in Indonesia, Thailand and Vietnam from January 2001 to May 2018. Data analysis used Johansen cointegration model and is estimated using a vector autoregretion in different using two different research models. The difference between the first and second models is differentiated in the endogenous variables of Indonesian rice prices, the first model uses the price in dollars while the second model uses the rupiah. In the second model, enter the exogenous variabel exchange rate into the model. The cointegration Johansen test results show that there is no market integration between the Indonesian market with Thailand and Vietnam. The results of the VAR in different test show that the short-term integration that occurs between Indonesia-Thailand and Indonesia-Vietnam is weak. Market integration was not formed due to the rice import policy and price stability implemented by the Indonesian government to protect domestic farmers and consumers..

Abstract : The price of commercial feed, which is becoming more expensive, has caused the need for alternative fish feed with the same quality but at a lower price. The feed costs are the most significant component in catfish farming. The larvae of Black Soldier Fly or maggots can be used as an additional alternative feed. This study aimed to determine the efficiency of feed costs by providing additional maggot feed-in Sangkuriang catfish cultivation. Furthermore, the effect of giving maggots was also analyzed in the feasibility business of catfish farming. The results showed that the most efficient feed cost was a combination of 50% commercial feed in the form of pellets and 50% maggots. This combination of feed reduced costs by IDR 675 / kilogram of feed. The business feasibility indicator of this combination of feed showed better results than the use of pellets only. NPV increased to IDR 1,831,038, IRR of 64.41%, Net B / C with a value of 2.36, and the Pay Back Period improved at 15 months. Thus, the best recommendation for Sangkuriang catfish cultivation is a combination of 50% commercial feed and 50% maggots..

Abstract : Broiler chicken meat is a strategic commodity that is growing rapidly, produced by the livestock sub-sector. West Java Province is the main producer of broiler chickens in Indonesia. This study aimed to analyze the price transmission in the supply chain of broiler chickens. This study used an asymmetric NARDL model. The data used were monthly data on farmer, wholesale and retail from January 2014 to December 2019. The results show that in the farmer-wholesales relationship, there is a long-term price asymmetry, as well as wholesale-retailer relationship. Meanwhile, the relationship between farmer and retail does not occur in the long term asymmetrical relationship. The result also suggests to improve the structure of the broiler market is that the government needs to provide facilities for smallholder farmers to join independent farmer groups..

Abstract : Postharvest quality of eggplant fruit diminishes rapidly after harvest especially if placed or displayed in inappropriate storages which is very evident in local markets of Samar. Calcium as major element needed by plants, it is reported to promote postharvest qualities of vegetables. A study was arranged in Randomized Complete Block Design (RCBD) to evaluate the effects of calcium derived from organic source (eggshell and “kohol” shell) and chemical fertilizer (calcium nitrate) on the postharvest qualities, horticultural characteristics and yield components of eggplant. Results showed that yield components and growth parameters in terms of height was enhanced applied with different source of calcium (calcium nitrate, eggshell, “kohol” shell) compared to control while the days to flower initiation, number of flowers and leaves were not significantly different. Postharvest qualities of fruits was improved in plants treated with calcium. Weight loss was minimal in plants applied with calcium nitrate. Carbon dioxide percentage and respiration rate were also minimal in plants applied with calcium wherein calcium nitrate had the least CO2 production (0.37 to 0.13 %) and respiration rate (0.0275 to 0.0148 %). Visual quality appearance and firmness of fruits was prolonged with application of calcium both organic and inorganic compared. Results suggests that calcium application could improve the growth, yield, postharvest qualities of fruits and eventually the storage/shelf life..
