This study used a factorial randomized block design (RBD) with two factors, and was repeated three times. The results showed that water immersion had no effect on coffee seed germination, rice water immersion for 6 hours had an effect on plant height at planting age of 4 WAP and 11 WAP, and there was an interaction between water immersion time and rice water immersion time at 12 WAP planting age. The best combination is 12 hours of water immersion + 12 hours of rice washing water on wet weight of shoot and dry weight of shoot.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49214507","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}

To increase cotton production, the development of superior varieties using plant breeding methods in cross-analysis is necessary. The cross-analysis method is used to determine the agronomic traits that affect cotton production, by selecting yield through several other characteristics related to yield. The aim of this study was to identify which agronomic characters can be used as selection criteria to increase cotton production using cross-analysis. The research was conducted at Politeknik Negeri Jember, and included 12 independent variables and one response variable, namely cotton production. The method used in this study was to perform correlation analysis, cross-analysis, calculate direct and residual contributions, and select agronomic characters that can be used as selection criteria. The results showed that the number of fruit characters had the highest correlation with cotton production (RX9Y = 0.835). Cross-analysis was carried out, and the highest direct effect was found between the number of fruit characters and cotton production (PX9Y = 0.971). The highest direct contribution was found in the character of the number of fruit, which had a total contribution of 98.321% and residue of 1.679%. Therefore, the agronomic character that can be used as a direct selection criterion is the number of fruits.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45571302","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}

Additionally, robusta coffee has a higher caffeine content. Coffee quality is evaluated based on the quality of green coffee beans and the taste of the brewed coffee. A good and delicious coffee taste can be achieved by roasting the coffee beans correctly and using high-quality green coffee beans. This study was conducted to evaluate the taste of quality 1 robusta coffee beans with different sizes - L (7.5 mm in diameter), M (6.5 mm in diameter), and S (5.5 mm in diameter). The experiment was carried out using a simple randomized block design and analyzed using analysis of variance, followed by the LSD test with a 5% significance level. The research was conducted at a coffee processing factory in Satak village, Kediri, East Java in March 2022. The taste testing of the robusta coffee was done using the cupping test method according to the Specialty Coffee Association of America (SCAA) standards. The results of the analysis indicate that the taste of quality 1 robusta coffee beans is significantly affected by the size of the beans in terms of fragrance, flavor, balance, sweetness, and overall taste. Based on the cupping coffee quality classification scores, robusta coffee beans 1S, 1M, and 1L scored <75, which means they are of low quality and considered off-grade.","PeriodicalId":34207,"journal":{"name":"Jurnal Agro Industri Perkebunan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49047999","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}
