Abstract

Low cocoa productivity, especially in smallholder plantations, is caused by soil conditions showing symptoms of "soil fatigue", increasing old plants, attacks by cocoa fruit borers (PBK), and vascular wilt (VSD), and fertilization that is not in accordance with the dose. This study aims to determine the intensity of attacks by cocoa fruit-sucking ladybugs (Helopeltis sp.) on smallholder plantations in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency. This research was conducted from March to August 2024 on smallholder plantations in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency. The method used in this study is the survey method. The procedure for determining the location of the study was carried out by purposive sampling. A total of 2 plantation locations became research areas with a land area of 1 ha each. The distance between the two locations is ± 1 meter. The observation method is carried out by transect or surrounding the garden according to the predetermined direction of the track. The number of plant populations at locations 1 and 2 was 600 stems (>100) so 15% of the sample plants were taken so that the number of sample plants taken was 15% of the 600 plants = 90 plants. The variables observed in this study were the type of clone and age of the plant, the number of shade plants and light intensity, the number of main branches of the cocoa plant, agronomic measures, temperature and humidity, production estimates, the level of ladybug pest attacks, the intensity of ladybug pest attacks on each plant. The results showed that cocoa plants were cultivated with a polyclonal system using MCC 02, S1 and S2 clones. The age of the plants varied with a range of 7 to 15 years. The permanent shade used in cultivation was the duku plant with a planting distance of 10 x 10 m. Standard agronomic actions have been carried out on plantation 1 and plantation 2, only the maintenance intensity is much better on plantation 1. The intensity of cocoa fruit sucking ladybug pest attacks on the people's plantation in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency in plantation 2 was 53.08% and on plantation 1 was 22.38%. The level of fruit sucking ladybug pest attacks on the people's plantation in Betung Village, Kumpeh Ilir District, Muaro Jambi Regency in plantation 2 was 63.37% on plantation 1 was 35.18% 1. The level of attack and intensity of fruit sucking ladybug pest attacks in this study were included in the moderate category for plantation 1 and severe for plantation 2. Agronomic actions, level of attack, intensity of fruit sucking ladybug pest attacks caused differences in production, plantation 1 was 842.4 kg/ha/year and in plantation 2 was 576 kg/ha/year

Abstract

The deterioration process in seeds cannot be prevented. One effort to reduce the rate of deterioration is to optimize storage conditions and the appropriate storage period. Optimal storage conditions and the appropriate storage period can maintain seed quality during storage and growth after storage. The study aimed to obtain data on the rate of seed deterioration and growth of citronella plants after storage. The study was conducted from April to August 2025 in the basic laboratory and experimental garden of the Faculty of Agriculture, Batanghari University. The study used a completely randomized design with one factor. The treatment design was the storage duration (h, days) of citronella seeds as follows: h0 = not stored, h1 = 4, h2 = 8, h3 = 12, and h4 = 16 days. Each treatment was repeated 3 times, resulting in 15 experimental plots. Each experimental plot contained 10 seeds, resulting in 150 citronella plant seeds. Observations during storage were the percentage of fresh seeds and the percentage of growing seeds. Observations after storage were plant height, rate of emergence of tillers, number of tillers, clump circumference, fresh weight of herb, and fresh weight of roots. The observation data were analyzed using analysis of variance. If there was a significant effect, it was continued with Duncan's Advanced Test at α level of 5%. Based on the research and data analysis, it can be concluded that the treatment of the duration of storage of citronella seeds had a significant effect on clump circumference, but had no significant effect on plant height, rate of emergence of tillers, number of tillers, fresh weight of herb and fresh weight of roots. The longer the citronella seeds were stored, the growth rate tended to decrease. This is caused by a decrease in seed viability due to the aging process, dehydration, or physiological damage during storage.

Abstract

Roasting is a very important post-harvest stage in processing cocoa beans into derivative products because this roasting process will produce the characteristic color, aroma, taste and texture of the cocoa beans. The research was carried out from February to March 2023 at the Basic Laboratory of Batanghari University, Jambi. The study used a completely randomized environmental design. The treatment design is roasting time with 4 levels as follows: P1: 20 minutes, P2: 30 minutes, P3: 40 minutes, P4: 50 minutes. The variables observed were the moisture content of the dry cocoa beans, the color of the chocolate paste, the aroma of the chocolate paste, the taste of the chocolate paste, the liking of the chocolate paste, the bitterness of the chocolate paste. Organoleptic testing of color, aroma, taste, brownness and liking variables was carried out using a perception test with a 5-scale Likert scale. The data was tabulated, followed by analysis of variance, then continued with the DMRT test at the α level of 5%. Based on the results of the research and discussion, it can be concluded that different roasting times have no significant effect on the acidity (pH) of roasted cocoa beans, color, aroma, taste, bitterness and liking of chocolate paste. Roasting time of 20 minutes produces chocolate paste with a brown color, a favorable aroma, a favorable taste, a slightly bitter bitterness level and a favorable level of liking.

Abstract

The use of ultisol soil as a nursery medium is constrained by low soil fertility. This study aims to determine the growth of Areca nut seedlings (Areca catechu L.) in various compositions of vermicompost and NPK fertilizer in polybags to overcome the problem availability of nutrients in the soil. This study was conducted at the Experimental Station of the Faculty of Agriculture, Batanghari University on July 7 to November 2024. This study used a completely randomized design with one factor. The treatments were vermicompost and NPK fertilizer (k) with 6 levels as follows: k0=without vermicompost and NPK fertilizer, k1= 30 g vermicompost, k2= 10 g NPK fertilizer, k3= 22.5 g vermicompost + 2.5 g NPK fertilizer, k4= 15 g vermicompost + 5 g NPK fertilizer, k5= 7.5 g vermicompost + 7.5 g NPK fertilizer. The parameters observed were plant height, stem diameter, total leaf area, shoot dry weight, root dry weight, soil water content, root volume, soil chemical analysis. The combination treatment of vermicompost fertilizer with NPK fertilizer affected all parameters, namely plant height, stem diameter, total leaf area, shoot dry weight, root dry weight, and root volume. Based on data analysis, it can be said that the k5 treatment, namely a combination of 25% vermicompost fertilizer + 75% NPK fertilizer, will increase seedling height by 27.27%, seedling stem diameter by 50.10%, total leaf area by 65.40%, shoot dry weight by 64.55%, root dry weight by 130.57%, and root volume by 96.18% when compared to the control. The k1 treatment gave the highest value of planting media water content, increasing by 25.56% when compared to the control. The combination of vermicompost fertilizer with NPK fertilizer is highly recommended in areca nut cultivation. The cost of k5 fertilization increased by 7.25%, but there was an increase in seedling height of 12.5%; stem diameter 34.57%; total leaf area 49.23%; shoot dry weight 37%; root dry weight 35.58; soil water content 26.51%, and root volume 68%. The R/C ratio of areca nut seedlings was 1.87.
