Abstract
Abstract The supply chain of shallot commodities in Bantul Regency involves several business actors including farmers, middleman, collectors, wholesalers, retailers and small traders. In the process of each supply chain, risks will always be encountered. The risks in each tier of shallot supply chain certainly need to be identified and analyzed. The categories of each of these risks will determine the appropriate supply chain risk management steps based on the risk categories obtained. This study was conducted to analyze the risk of shallot supply chains in the three largest shallot producing sub-districts. The Rapid Agricultural Supply Chain Risk Assessment (RapAgRisk) method is used to carry out risk analysis, and the sampling method used was purposive sampling and snowball sampling. The results show that the farmer is the tier with most risks faced compared to the others. Excessive stock is the risk that requires adequate priority to manage, and it is faced by all levels of the shallot supply chain. Meanwhile, farmers are the weakest supply chain actors in bargaining power, and the small traders are the most vulnerable actors in the face of risks associated with quality damage and slow sales rate.

Abstract
Rice plant as staple food especially in tropical regions. One of the major problems encountered by Indonesian rice farmer is the pest and diseases infestation, causing loss of potential yield. Yield lost in Indonesia was reported annually shows more intense. The intensive pest and diseases attack on young rice plant forced farmers to invest more on plant protection measures. Farmers sometimes unaware of the symptoms of pest and diseases presence until severe lost occurred. This research aimed to analyze the pest and disease attack and dispersion on the rice field during the planting season. The method using spatial analysis to map and determine the spreading pattern of certain disease spread over the farmland. Four type of pest attack patterns analyzed i.e. rice bug, brown planthopper, rice leaf roller and stem borer. The result shows that the rice bug, brown planthopper and leaf roller have smaller spreading patterns whole the stem borer have wider spreading pattern.

Abstract
Indonesia has a tourist attraction that is currently starting to develop rapidly, namely farm based tourism. One of the efforts needed to develop farm based tourism is by providing agro tourism. Utilizing agriculture in tourism activities is an alternative, especially in an agrarian country such as Indonesia which has the potential of agriculture with many species diversity. One of the largest agricultural producer areas in Indonesia is West Java, especially West Bandung Districts. West Bandung Districts is one of the regions that has the potential for agro tourism development because the location is relatively cool. Most of the area is in the form of mountains with high rainfall around 1500 - 3500 mm / year so that it has fertile land, therefore the community mostly works in agriculture. The high number of farmers and agricultural production in West Bandung Districts has not been used optimally to be said as an agro tourism location. A study of aspects that affect the success and sustainability of tourist destinations is needed so that the potential in a tourist destination is known and becomes the basis for the development that will be carried out. This study uses a spatial analysis method that describes spatial patterns based on the potential of agro tourism land, and Community Based Tourism with the help of maps that will be seen in its distribution. Also using simple statistical analysis is the chi-square test to find out the correlation and then draw conclusions and describe briefly based on the research objectives.

Abstract
This study aims to examine the relationship between temperature and length of steaming of coffee beans using a closed system method to change the physical properties of seeds such as moisture content, development of volume, color and hardness. The experiment was conducted using 750 g of each Robusta coffee beans are separately steamed in an autoclave (closed system) at temperatures of 100, 110 and 120 oC for 1, 2, 3, 4, 5, 6 and 7 hours, respectively. Changes in the physical properties of seeds after steaming were analyzed using the Avrami equation model with the Microsoft Excel program. From the results of this study it was found that the higher the temperature and the longer the steamed coffee beans can increase the volume of coffee beans and water content contained, and the degradation of the color of coffee beans that are getting darker. The opposite decreases the hardness of steamed coffee beans produced. The color of the coffee beans darkens is marked by a decrease in the average value of lightness (L) from 25.32 to 10.8.

Abstract
This study aimed to determine the effect of manipulated cicada sound frequency on evapotranspiration and growth rate of cayenne pepper (Capsicum annum L.). The manipulated cicada sound was exposed with a frequency of 3000Hz, 4000Hz, 5000Hz and untreated under a completely randomized design. The exposure is performed every day in 60 minutes in the coldframe chamber for 43 days. Evapotranspiration, plant height and number of leaves are parameters that can be used as indicators of plant growth. The calculation of reference evapotranspiration was done using the Penman Mointeith method. From this study, it was found that the reference evapotranspiration on in the research site had met the standard of cayenne pepper cultivation. The results showed that the actual optimal evapotranspiration of cayenne pepper occurred in plants that were exposed to a frequency of 5000Hz which was equal to a 4,95 mm/day. While the most optimal growth in plant height and number of leaves occurred in plants that were exposed to a frequency of 5000Hz with an average height growth of 3,02 cm and the number of leaves increasing by 1-2 strands within 3 days. Statistically, the exposure of manipulated cicada sound has a significant influence on the actual evapotranspiration and the growth of cayenne pepper.

Abstract
Rice straw is one of the lignocellulosic substrate that has not been used optimally and mostly just become an agricultural waste if not handled properly. Cellulose and hemicellulose content in lignocellulose structures of rice straw has great potential for thermostable enzymes production from thermophilic bacteria. The purpose of this study were to determine the effect of pretreatment in rice straw substrate on the total number of bacteria and its enzyme activity. The method used in this study include straw flour production, bacteria isolation and multi-level batch selection system, themostable enzyme production, total bacteria and enzyme activity measurement. The results obtained were combination of alkaline delignification and pressurized steam heating treatment resulting higher microbial growth pattern than the pressure steam heating only. Observation of pH showed pH decreasing in each treatment. The enzyme activity obtained showed fluctuating results due to the presence of diauxie phenomenon.

Abstract
The purpose of this study was to found the distribution of Pyricularia oryzae races in three different regencies in South Sulawesi as well as gene analyze linked to the virulence character of P. oryzae in causing blast disease on rice. Determination of P. oryzae races was conducted using 1 set of rice differential varieties consisting of Asahan, Cisokan, IR 64, Krueng Aceh, Cisadane, Cisanggarung and Kencana Bali. Intensity of blast disease was observed seven days after inoculation using the IRRI evaluation standard using a 5-9 scale of necrotic area to determine the host resistance level. Molecular characterization of P. oryzae isolates code for their virulence characters was performed using primer Erg2 (1440 bp), Pwl2 (900 bp), and Cut1 (1730bp). The amplified DNA band appear for each primer of each isolate was evaluated with a value of 1 if present and 0 (absent). Out of 20 isolates were successfully collected: from Bone regency 8 isolates, from Maros regency were 8 isolates and from Gowa regency were 4 isolates. Inoculation of P. oryzae isolates on 7 differential rice varieties showed, that 12 races (000, 001,003,010, 020,023, 100, 102,110,111,173, and 251) were exist between P. oryzae isolates tested. However, the 020 race was dominant in all district. Using 3 primers coded for virulence of 10 P. oryzae isolates, only three haplotypes were found. There were haplotypes C-011, E-010, and F-110. Haplotype C-011 were most dominant (8 isolates), whereas haplotype E-010 and F-110 were present only in each one isolate respectively.
