Sugarcane is cultivated in Madura, particularly in four regencies, namely Bangkalan, Sampang, Pamekasan and Sumenep. To decide the location of mini sugar mill in one of the regencies requires decision support system (DSS). This study aimed to determine the priority of mini sugar mill location in Madura. This research used primary and secondary data. The primary data were collected using questionnaires. Then, the results of evaluation from the experts, on the items of questions, were analyzed with analytical hierarchy process (AHP). This was accomplished using Expert Choice 2000 software. Analysis of the selection of mini sugar mill location considered six criteria, namely the land suitability level, existing infrastructure, the potential of raw materials, the availability of labor, social capital and institutions. The selected criteria were further classified into sub-criteria to clarify the definitions of operational criteria and facilitate assessment for respondents. The results show that social capital had the greatest influence on decision making, followed by the land suitability level and the potential of raw materials. The finding in this research is that the mini sugar mill location is given priority in Bangkalan Regency, Madura. The conclusion of this research is that AHP analysis can be used as a method to take accurate decision in determining the location of sugarcane factory in certain area of sugarcane farming business development.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42960681","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}

This study aims to determine the calculations, perceptions and attitudes of farmers towards wheat farming, considering that Indonesia is a non-wheat developing country. This qualitative descriptive research using in-depth interviews with 7 informants and observation methods was conducted in Klaten and Demak Regencies. In analyzing the data, this study used an interactive analysis model including data reduction, data presentation and conclusion drawing. The results show that: 1) based on farmers' calculations, wheat farming is financially not profitable to farmers because the products harvested are not worth the expense; 2) farmers' calculations affect farmers' perceptions which shifted to negative perceptions that wheat farming is not as promising as other farming businesses. Despite the negative perceptions, wheat farming has provided a valuable experience for farmers which is shown by their pride and pleasure and 3) the majority of farmers are not interested in wheat farming, which is shown by their attitude of not being able to accept wheat farming, while other farmers behave otherwise, indicated by their willingness to recommence wheat planting testing. Further research may examine: 1) how to change the culture of rice farming into culture of wheat farming; 2) how to change subsistence rice farming into enterprise and 3) how to change rice farming as social activities to rice farming as business activities.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45948882","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}

This study aimed to investigate climate change-induced agricultural drought over the moist-cool and moist-warm climatic zones, using historical precipitation and temperature data recorded in the crop growing months for 35 years. The changes of temperatures and precipitation were analyzed using Mann Kendall trend test. Agricultural drought indices were analyzed using R-model by withdrawing potential evapotranspiration from precipitation to determine the existing water balance. The values of drought indices were used to characterize the duration, severity, intensity and trends of agricultural drought. Results showed that the changes in maximum and minimum temperatures and precipitation were significantly stronger in the Ale Woreda (P<0.05). However, minimum temperature and precipitation in Adami-Tulu did not noticeably change. The spatial drought events occurred more widely in Ale than in Adami Tulu. The events occurred 12 and 17 times with cumulative severity indices of 41.95 and 48.22 in Ale and Adami-Tulu, respectively. Agricultural drought intensities of the two districts were labeled as “severe” and “moderate dry”, for Ale and Adami-Tulu, respectively. The intensity of drought in Ale district significantly increased (P<0.05) and that in Adami-Tulu negligibly changed. Therefore, the study explicitly showed that more changes in temperature and precipitation aggravated agricultural drought in Ale than in Adami-Tulu more intensely and it is suggested that more attention shall be paid to Ale Woreda.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42341523","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 study used a Completely Randomized Design (CRD) with two treatment factors: transplanting techniques (puteran, cabutan, stump) and water availability (50, 37.5, 25, 12.5% water field capacity). Observation data were analyzed by analysis of variance and followed by DMRT test at 5% upon the significant result.

This research was conducted from March to July 2018 at Pakahan Village, Jogonalan Sub-district, Klaten Regency, Central Java, using a Randomized Complete Block Design (RCBD). The variables observed were plant height, total number of tillers and productive tillers, panicle length, number of seeds per panicle, panicle intensity index, weight per panicle, 1,000 seed weight, seed weight per plant, flowering age, harvest age, plot yield, yield per hectare, rice color and total anthocyanin content. Variance analysis showed that there was a very significant difference (p <0.01) among the genotypes tested for all observed characters indicating variability. In this study, the phenotypic coefficient of variance (PCV) values was relatively higher than the genotypic coefficient of variance (GCV) for all traits. However, GCV values were close to PCV values in some characters such as plant height, flowering age, harvest age, rice color and anthocyanin content which showed a high contribution of genotypic effects to the phenotypic expression of these characters. The high heritability and high average value of genetic advance were indicated in the parameters of plant height, flowering age, harvest age, rice color and anthocyanin content. The characters of plant height, flowering age, harvest age, rice color and anthocyanin content can be used as sixth-generation black rice selection criteria.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42561346","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 pollution index of the river water in dry season has reached polluted to extremely polluted levels and the index of the river water in rainy season has reached moderately polluted to polluted levels. This condition shows that the practice of dumping waste into river bodies can directly affect river water quality.
