The objective of this research was to determine the resistance variability of Arabica coffee genotypes to leaf rust disease and its relation to leaf morphology.  A total of 84 genotypes grown in North Sumatra were selected in November 2015 and 2016, and December 2017 using a nested design.  Data were analyzed using nested design, correlation, stepwise regression, and cluster hierarchy analysis. The result showed that the G56 genotype performed the most resistant to leaf rust disease, with a severity of 5.21%.  The severity of leaf rust disease has high genotypic variation, low heritability, and high genetic advance.  Leaf morphological ratios showed moderate to high genotypic variation and heritability.  The severity of leaf rust (y) significantly correlated with the ratio of leaf length to leaf area (x1) and the ratio of leaf length to leaf width (x2) with the equation y = 2.04 + 62.48x1 - 3.95x2, and multiple correlation coefficients R = 0.470 **. By using the leaf rust severity and the two ratios in the cluster analysis, these 84 genotypes were grouped into five clusters.  The result showed that several Arabica coffee genotypes with a high level of resistance to leaf rust disease are potential to be further developed.","PeriodicalId":201337,"journal":{"name":"Jurnal Tanaman Industri dan Penyegar","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124905075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of this study were to: (1) analyze the level of institutional support for cocoa farmers in Central Sulawesi Province, and (2) analyze the role and strategy of increasing institutional support for cocoa farmers in Central Sulawesi Province. The study was conducted in four districts in Central Sulawesi Province: Poso, Sigi, Morowali Utara and Donggala Regencies. The research sample was 380 farmers. To describe the research variables used descriptive statistical analysis in the frequency table and Duncan’s Multiple Range Test (DMRT). The results showed that most farmers (70.2%–98.7%) assessed that institutional support in the contexts of marketing, capital, processing, and technical guidance were relatively low so it tended to be less conducive to increasing farmers' independence. The institutional role of those four contexts was also low categoryzed (26.6–43.0) so that it needs serious attention in an effort to increase the weak independence of farmers.","PeriodicalId":201337,"journal":{"name":"Jurnal Tanaman Industri dan Penyegar","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116771944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research location was determined by purposive sampling and 72 respondents were randomly chosen from Arabica coffee farmer population in Garut Regency. The data was analysed using stochastic frontier production, estimated by Maximum Likelihood Estimates (MLE) method. The results showed that the factors influencing the technical efficiency of coffee farming are land area, use of Urea fertilizer, ZA fertilizer, SP 36 fertilizer, herbicide and labor. The technical efficiency of farmers is quite high (average of 0.81). Means farmers have been technically efficient especially in allocating resources and utilizing existing cultivation technology.

The research was carried out at the experimental station of Indonesian Coffee and Cocoa Research Institute in Malang Regency (ICCRI) and ICCRI laboratory in Jember Regency from July 2018 to January 2019. Experiments used factorial completely randomized design. The first factor was cherry soaking duration (0, 24, 48, and 72 hours) and the second factor was fermentation duration (0, 24, and 48 hours) and then combined into 12 treatments, with three replications. Ten kilograms of coffee cherries were soaked prior to pulping then fermented in a plastic bag and added with Lactobacillus casei 2,5 x 107 cfu/ml as starter.  Parameters observed were color of hull skin (L value, a*, dan b*) and the cup quality.  The results showed that soaking the cherry decreased the green beans quality which is indicated by less brightness (L), high a* value, and decreasing b* value of hull skin color. While the fermentation treatment can increase the value of L, decrease the a* value, and increase the b* value. The interaction of treatment of soaking and fermentation time significantly affected the lightnessl a* and b* value. Soaking and fermentation treatments did not significantly affect to the flavor, salt/acid, balance, and total score of coffee flavor.

Data collected included strengths, weaknesses, opportunities, and threats faced by FOE which were then analyzed using Strength, Weaknesses, Opportunities, Threats (SWOT) method to formulate an FOE development strategy. The strategy was then compiled based on priorities with Analytical Hierarchy Process (AHP). The results formulated three strategies, namely: (1) increasing production of quality feed to meet the needs of dairy cattle, (2) producing competitively priced compost from cow manure, and (3) establishing market partnerships with coffee exporters.

The liquid smokes made from cacao pod husks, sawdust, coconut shells, and rice husks. Phytochemical content of liquid smokes was analyzed qualitatively and quantitatively using gas cromatografy mass spectrometry (GCMS). Toxicity analysis was carried out by residual and contact methods at concentrations of 1%; 1.5%; 2%; 2.5%; controls (aquades), and chlorpyrifos insecticide (2 ml/l) as comparison. Each treatment used 15 H. hampei imagos, repeated 3 times. Mortality parameters were observed at 24, 48, 72, 96, and 120 hours after treatment (HAT). To investigate antifeedance, 10 coffee fruits were infested with 20 imagos  in plastic containers, repeated 3 times and parameters observed were the number of holes at 1, 2, 3, 4, 5, 6, and 7 days after infestation. The results showed that the largest component in liquid smoke presumably functioned as insecticides are Benzenesulfonic acid 4-hydroxy and Acetic acid.
