Perubahan Produksi dan Perdagangan Negara-negara Produsen Lada Terbesar di Dunia dan Implikasinya bagi Indonesia
Full text linkThe production and trade of agricultural products in global markets will undergo changes due to shifts in demand and production patterns. Although demand for pepper is likely to remain strong, pepper production is prone to fluctuations due to various factors, particularly natural ones. This study aims to predict future changes in the production and trade of the world's largest pepper-producing countries and identify macro-level improvements needed to enhance the pepper production and trade system in Indonesia. Using time-series analysis (i.e., double exponential smoothing) with FAOSTAT data from 1961-2020, this study predicts that the competitive landscape among pepper-producing countries is likely to change over the next 15 years. Some producing countries may overtake others in terms of pepper production and trade. Consequently, Indonesia needs to respond to these changes by implementing various sectoral-level improvements, such as investing in sustainable development, improving infrastructure, and addressing political factors, in addition to improving farmer-level practices.The production and trade of agricultural products in global markets will undergo changes due to shifts in demand and production patterns.

Pengaruh Ukuran Biji Kopi Robusta pada Kualitas Citarasa Kopi
Full text linkRobusta coffee is known for its bitter taste and stronger aroma compared to arabica coffee. 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.Robusta coffee is known for its bitter taste and stronger aroma compared to arabica coffee.

Full text linkThe cotton plant is a fiber plant that is commonly used as a raw material for textiles, beauty, and health products. 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.The cotton plant is a fiber plant that is commonly used as a raw material for textiles, beauty, and health products.

Full text linkSelo District has great potential for developing plantation crops; however, the amount of production still needs to grow. The purpose of this study is to determine the soil suitability class of plantation crops (arabica coffee, tobacco, cloves, cocoa, and tea), identify limiting factors in the study area, and suggest ways to overcome them to increase land suitability classes. The study was conducted in Selo District, Boyolali Regency from November 2022 - December 2022, and the Plant Ecology Laboratory, Faculty of Animal Husbandry and Agriculture, Diponegoro University. This study used an investigative method consisting of multiple stages, laboratory data analysis, and data processing. As a result, Selo District has actual land suitability N (not suitable) for Arabica coffee and Cocoa in all area tests. In contrast, tobacco, clove, and tea had suitability classes S3 (marginally appropriate) to N (not suitable). The limiting factors that dominate are air humidity, pH, C-organic, soil texture, and slope. Efforts can be made to improve the limiting factors in the area by adding fertiliser and organic matter, feeding dolomite, and making mounds. These improvement efforts aim to increase the land suitability class for plantation crops.Selo District has great potential for developing plantation crops; however, the amount of production still needs to grow.
