Published: March 2018

Orange fleshed sweet potato contains high beta carotene as vitamin A precursor. However, its production is limited by the presence of scab disease caused by Sphaceloma batatas Saw. The disease is able to cause yield loss up to 60%. Best controlling method is using resistant varieties. However, the development of resistant varieties are involving long procedures which is time consuming. The long procedure of resistance varieties selection can be shorted cut using molecular markers such as SSR (Simple Sequence Repeats). Specific SSR markers for sweet potato resistance against scab has not been found. This study aimed to screen SSR molecular markers which were related to resistance to scab. The study used 5 resistant genotypes, 5 susceptible genotypes, and 6 SSR primers. PCR analysis showed that those SSR primers were polymorphic. Furthermore, the biplot analysis result demonstrated that several markers allele were related to plant resistance against scab. This finding indicated that these particular SSR markers can be used in sweet potato breeding program as marker assisted selection to develop resistant variety against scab disease. Keywords: Sphaceloma batatas; orange fleshed sweet potato; SSR markers.

Published: March 2018

Isolation was attempted to collect endophytic bacteria as potential biocontrol agents against rice blast disease (Pyricularia oryzae Cav.). The disease is one of major threats in rice production as it can cause 100% yield loss. Concern on the environment and human health has led to the searching of alternative controlling method to replace the commonly used pesticide-based method. Endophytic bacteria are bacteria that have intimate relationship with their host without inducing any pathogenic symptom. The use of endophytic microbial as biocontrol agent has its own advantages as the microbes are more easily to adapt to the environment needed by the host plant. We evaluated endophytic bacteria isolated from healthy rice plants and tested for their potential biocontrol activity using dual culture assay. Ten isolates were found to inhibit the growth of P. oryzae of more than 50%. Microscopic observation showed that they were able to cause the mycelia malformation of P. oryzae. Further work is currently in progress to determine their effectiveness in the pot trial. Keywords: Endophytic bacteria; Pyricularia oryzae; biocontrol.

Bacterial wilt disease (Ralstonia solanacearum) is one of the most important diseases in Solanaceae, including chili. Biological control is one of environmentally-friendly method for controlling plant diseases. Microbes that are potential as biological control agents include bacterial endophytes and bacteria that are usually used as biofertilizer. This paper discusses the result of the study that examined the abilities of endophytic and biofertilizing bacteria solely or in combination to suppress bacterial wilt disease (R. solanacearum). The endophytic bacteria isolates tested were Lysinibacillus sp. and Bacillus subtilis, while biofertilizing bacteria used were N-fixing bacteria (Azotobacter chrococcum) and P-solubilizing bacteria (Pseudomonas cepacea). The results showed that the endophytic bacteria, biofertilizing bacteria and their combination inhibited wilt disease incidence in chili by 46.7-80 %. The highest disease suppression (80 %) showed by the endophytic bacteria, B. subtilis. This endophyte was also able to promote a significant chili growth.

Published: March 2018

Indonesia horticultural product has experienced major implication from global free trade. Quantity of imported fruits was increased rapidly during the last ten years under implication of free trade. In spite implies market positively by boosting consumption and market growth, imports also implies increasing competition between imported and local fruit. Increase of imports has significantly affect production by decreasing number of certain scale of farm whose growth local product. It is important measuring whether the market and costumer response due the competition between locally grown and imported fruits. The study intended to (1) examined the difference of demands between local citrus and imported one. (2) measured demographic factors that influence costumer choice to buy local or imported citrus, and (3) examined product attributes that influence consumer willingness to pay (WTP) for local and imported citrus. The study was conducted in Malang district, East Java, Indonesia. Respondents were determined by purposive quota sampling method. WTP data was collected refer to modified “Vickrey Auction” principles. Binary Logit Regression and Ordinary Least Square analysis have been employed respectively to measure demographic factor that influenced costumer decision and examine the product attributes related to costumer WTP. The study has revealed that there were a different demand curve pattern and different own price elasticity between locally grown and imported citrus. Higher Income, higher number of dependant and younger costumer has driven higher probability on consuming imported citrus. This research also shown that color, safety, healthy and packaging significantly affect costumer willingness to pay for imported citrus, while taste and safety was significant for local citrus. The findings indicated that in certain market, consumer would pay higher price to afford imported citrus, which placed locally grown citrus in the high competition. Higher incomes will increase imported citrus consumption. Meanwhile, color and packaging are factors that must be considered by citrus local grower to win the competition.

Published: March 2018

This study aimed to analyze the impact of land area expansion policy of paddy and corn crops towards food self-sufficiency in Indonesia. Analyses were performed by using CGE models based on the SAM data and Input Output Table of Indonesia in 2008. The result showed that the increase of land area of paddy and corn by 4-10%, the paddy production will rise 36,21-87,93%, while the corn production is relatively constant even going down to 0,55%. If the land of paddy and corn increased by 4-10%, it will decrease the export of almost all sectors in Indonesia, except the food and beverage industry whose increased 52-118,12%, as well as fertilizer and pesticide industries whose are relatively constant. On the other hand, the land area expansion of paddy and corn 4-10% will not affect the import of this commodity. Thus, it can be concluded that the land area expansion of paddy and corn crops have a positive impact on food self-sufficiency (rice and corn) in Indonesia.

Published: March 2018

Farmer's risk aversion determines the decision to farming, especially in organic farming. In Indonesia, organic farming still has not shown encouraging progress, whereas movement "Go Organic" has been initiated by the government since 1980 after the green revolution program was stopped. Organic agriculture has the potential failure obstacles in the process of production and farming. International policy, human resources, government supporting, land, water, local seeds, marketing, climate, can be sources of risk in organic paddy farming in developing countries. The farmer’s risk aversion become crucial issues that influencing the production resulting from using a combination of inputs. Purposes of this study are a) analyzing sources of risk in organic farming, b) measuring the risk behavior of farmers and c) analyzing the effect of the risk behavior of farmers to production. The location of this research is purposive with consideration that the location is an organic rice production centres in Malang. The method to determine the respondents is census method. The method used a) quantitative descriptive, b) quadratic utility functions of the Bernoulli principle with technical-NM and c) Stochastic Frontier production function. The study found that the dominant source of the risk faced by organic paddy farmer is local rice seedlings are susceptible to pests and diseases, the behavior of most farmers are risk neutral and there is a positive and significant influence between behavior risk with productivity, causing the efficiency to be 93.31%. It is hoped with this study can be used as a reference for the government in the development of organic farming in the framework of "Healthy Indonesia".

Published: March 2018

The Indonesian beef price movement increasing erratically and tends to be volatile in recent years. Based on the price monitoring in several production centers, there are beef price fluctuations in the consumer level across time and between provinces. This study tries to present the relationship between the beef price volatility and Indonesia’s efforts to ensure food security through self-sufficiency in beef. We consider a series of consumer daily beef price from January 2006 to December 2013, with total T=2086 observations to understand beef price volatility in Indonesia, and to analyze the impact of beef self-sufficiency program to the beef price volatility in Indonesia. Data was obtained from Ministry of Trade, Government of Indonesia and it was collected through market survey from three different markets in 33 capital provinces in Indonesia. The methodology follows GARCH model to measure the beef price volatility. The GARCH (1.1) model gives information that beef price movements are influenced by the volatility from the previous period and yesterday’s variance. The volatility of beef price was driven more by its own variance rather than external shocks. GARCH (1.1) model shows that the beef price volatility will tend to be smaller and persistence in the future. Parameter of the third dummy variable in the variance equation to capture the change policy is statistically significant. It indicates that the beef self-sufficiency program may lower the beef price volatility. Keywords: beef price, garch model, price volatility, self sufficiency

Corn is one of strategic commodities becoming the main priorities to be developed in Indonesia. Aside from being a strategic foodstuffs, corn contains starch which is used for an excipient in pharmaceutical raw materials of "filler" or filler material for tablets. However, until now local starch production cannot meet the needs of the pharmaceutical industry in Indonesia, and still relies on imported starch. The purpose of this research was to develop maize hybrids from Universitas Padjadjaran which has high of starch and meet the quality for an excipient of pharmaceutical preparations. This research was conducted to determine a formation of a single cross hybrid based on the diallel crosses. Evaluation of fused power was determined by proximate analysis and starch analysis. The selection of hybrid high yield power was done in monocropping and agroforestry systems. The results retrieved 28 types of hybrid corn that comes from 7 different types of strains of mutant reproduction results. The lowest moisture content was the corn M7DR 7.4.1 (9.45%), whereas the highest moisture content of corn was DR. 8 (16.03%). Low starch content was obtained from maize hybrid code 4.8.8 while the highest was obtained from maize hybrid code 18.5.1 ranging from 30-40%. Therefore, corn hybrid 18.5.1 has a potential to be developed as an excipient of various raw materials in the field of pharmacy. Keywords: corn, a hybrid, starch, excipient pharmacy
