Abstract

Forcipomyia spp. is a pollinator insect on cacao plants that belongs to the Ceratopogonidae Family, Diptera Order. The objectives of this research were to determine the abundance of the insect population of Forcipomyia spp. in Lima Puluh Kota District and to determine the frequency of visits of those insects to cacao flowers. This research was conducted on a small smallholder plantation in Sungai Talang Village, Lima Puluh Kota District. Then, the samples obtained were identified at the Andalas University Laboratory. This research was conducted using a survey method and purposive sampling technique. Five cacao plants were selected in each plot of land, and then three flower beds per plant were selected to bloom. Sampling was carried out by installing yellow sticky traps. The insects obtained were put into a collection bottle filled with 96% alcohol to preserve those insects, and then the abundance of Forcipomyia spp. Insects were calculated. The research results showed that the highest insect abundance was in Jorong Guguak Nunang: 1.260 individuals, then in Jorong Bukik Apik: 1.061 individuals and the lowest was in Jorong Boncah: 1.045 individuals. The highest frequency of visits was in the morning, with an average of 648 individuals/60 minutes. The insect diversity index based on the Shannon-Wienner Diversity Index in Jorong Guguak Nunang was 1,97; in Jorong Boncah, it was 2,21; in Jorong Bukik Apik was 1,88, and all of it is in the medium diversity level category.

Abstract

The oil palm ecosystem is one of the suitable habitats for the order Dermaptera. Several physical factors, especially humidity in the oil palm ecosystem, support these insects' existence. In the oil palm ecosystem, Dermaptera has several functions, including as a predator of oil palm pests, but on the other hand, these insects also prey on Elaeidobius kamerunicus Faust, the primary pollinator of oil palm plants. For that reason, research was conducted to study the structure of the Dermaptera community in the ecosystem of oil palm plantations in the Sitiung sub-district. This research was a survey conducted at three locations- Sitiung, Gunung Medan, and Sungai Duo Villages—the collection of insect samples by hand collection. Identification of insect samples was carried out at the species level according to Burr (1910) and Borror et al. (1996). In this study, 214 individuals of the order Dermaptera were found to consist of three species: Cheslisoches mario, Forficula auricularia, and Vostox brunneipennis. C. mario was the dominant Dermaptera species found with an Importance Value Index (IVI) was 1.27. Based on this research, it is known that the community structure of the order Dermaptera was simple because it has low diversity values.

Abstract

Coconut (Cocos nucifera) plays a crucial role in agricultural economies, particularly in coconut-producing regions, where traditional de-husking methods are labor-intensive and time-consuming. This study focuses on the design, fabrication, and evaluation of a coconut de-husking machine aimed at improving processing efficiency, reducing labor demands, and increasing throughput. The machine was designed to address key performance factors such as frame stability, blade strength, and spring tension. Testing demonstrated that the machine consistently outperformed manual methods, reducing de-husking time to an average of 96.4 seconds compared to 164.8 seconds for traditional techniques. The machine achieved an efficiency rate of 80%, with a throughput capacity of 0.0086 kg/s, significantly higher than the manual method's 0.005 kg/s. Additionally, the machine's cost, approximately N32,000, makes it accessible to smallholder farmers, offering a practical solution for improving productivity and sustainability in coconut farming. The study highlights the potential for mechanized de-husking to transform traditional practices, reduce labor costs, and contribute to economic growth in coconut-rich regions. Future research should explore further optimization of the machine design and its adaptability to different coconut varieties and moisture levels, ensuring broad applicability in diverse farming contexts.

Abstract

Cocoa plants are one of the important commodities in plantation crops. The decreasing cocoa production is caused by several factors, one of which is pest attacks. There are several main pests in cocoa plants, namely, fruit borer pests, fruit sucking pests and lice. Currently, the use of chemical insecticides has been widely studied, causing many residues that can pollute the environment and disrupt the stability of the agro-ecosystem. One alternative that can be used is the use of attractants, namely pheromones derived from plant extracts containing essential oils. The use of pheromones with the trap method is one of the insect trapping techniques that has been widely used in control. The purpose of this study was to obtain the best combination of essential oils as vegetable pheromones to control pests in cocoa plants. This study consisted of six treatments and three replications. Treatment consists of use of vegetable pheromones derived from patchouli oil, cinnamon oil, oil nutmeg, clove oil, control (water) and combination (all treatments).

Abstract

Coffee is one of Indonesia's prominent tree commodity plants. In both generative and vegetative propagation, one crucial consideration is the choice of growing media rich in macro and micro nutrients. This study aims to investigate the effect of different ratios of palm oil empty fruit bunch (TKKS) and the addition of NPK fertilizer on the growth of robusta coffee seedlings. The research was conducted from January to May 2024 at the Innovation Garden, State Polytechnic of Jember. This study employed a factorial Randomized Complete Block Design (RCBD) with 2 factors, each having 3 treatment levels. The first factor was the growing media ratio: T1 = Top Soil : TKKS : Sand (1:1:1), T2 = Top Soil : TKKS : Sand (2:1:1), T3 = Top Soil : TKKS : Sand (1:2:1). The second factor was NPK fertilizer application: N1 (1 gram NPK/polybag), N2 (1.5 grams NPK/polybag), N3 (2 grams NPK/polybag). These combinations resulted in 9 treatment groups, each replicated 3 times, totaling 27 experimental units. Data were analyzed using ANOVA, followed by Tukey’s HSD test at a 5% significance level (p < 0.05), using SPSS version 25. The results showed that the T3 growing media (1:2:1) significantly increased seedling height by 18.7%, stem diameter by 15.2%, leaf number by 17.4%, and root length by 22.5% compared to T1 (p < 0.05). Application of 1.5 g NPK/polybag (N2) increased seedling height by 12.3% (p < 0.05) and root length by 19.8% (p < 0.01) compared to N1. A significant interaction (p < 0.05) was observed between T3 media and 1.5 g NPK/polybag, specifically enhancing root length, indicating a synergistic effect on root development.

Abstract

One of the stages in the wet processing of coffee that can affect its flavor is fermentation. Fermentation is the process of removing the mucilage layer that still adheres to the coffee beans, which results in a distinctive coffee aroma and reduces caffeine content, especially in robusta coffee. After the fermentation process, packaging and storage are carried out. Storage is the stage where raw coffee beans are kept to maintain their quality until the next process. This study aims to determine the effect of fermentation duration on panelists' preference levels and the impact of storage duration on the physical quality characteristics of robusta coffee. This research employs both quantitative and qualitative descriptive methods. The results show that storage duration does not affect the physical quality characteristics of robusta coffee beans. The moisture content parameter after storage was found to be 12.2%, the density parameter averaged 0.691 gr/ml, and the defect value parameter fell into grade 3. The study also shows that different fermentation durations do not significantly affect the panelists' preference levels, with an average score of 3-4,1.

Abstract

Coffee is one of the plantation commodities that has significant economic value. A factor that needs to be considered in coffee plant cultivation is good planting media composition. This study aims to determine the effect of planting media composition on the growth of robusta coffee seedlings. This study used a Completely Randomized Design with treatments M0= Soil: 100%, M1= Soil: 50% + Coffee Husk Compost: 25% + Rice Husk: 25%, M2= Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25%, M3= Soil: 25% + Coffee Husk Compost: 25% + Rice Husk: 50%. The analyses conducted were compost analysis and initial and post-incubation soil analysis. Observation data were analyzed using the F test followed by DNMRT at the 5% level. The research results show that the provision of coffee husk compost and rice husks affects the chemical properties of the soil and the growth of coffee seedlings. The planting media composition of Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25% proved to increase the pH of the planting media from 5.5 to 6.6, increase in total N-value from 0.2% to 0.5%, available P from 18.6 ppm to 38.5 ppm and the soil CEC from 7.6 me/100g to 36.6 me/100g. This planting media composition also makes it possible to enhance the growth of robusta coffee seedlings in plant height, stem diameter, number of leaves, leaf width, and root volume. Thus, this planting media composition is a suitable medium for the growth of robusta coffee seedlings.

Abstract

Coffee is an important agricultural commodity with increasing global demand, so optimizing the growth of coffee seedlings, especially during the seedling phase, is crucial to increase productivity. The use of natural plant growth regulators offers an environmentally friendly and economical solution. This study aims to evaluate the effect of natural plant growth regulators from onion extract and bean sprout extract on the growth of robusta coffee seedlings (Coffea canephora L.) during the seedling phase. The study was conducted using a Randomized Block Design (RBD) with three treatments, namely control, onion extract, and bean sprout extract. The parameters measured included plant height, stem diameter, and number of leaves for six weeks. Data were analyzed using ANOVA and BNT test at the 5% level. The results showed that both natural plant growth regulators significantly increased the growth of coffee seedlings compared to the control. Bean sprout extract gave the best results for plant height (16.75 cm), while onion extract was superior in increasing stem diameter (4.65 mm) and number of leaves (12.20). Statistical analysis confirmed significant differences between treatments and controls for all parameters. Thus, the use of onion and bean sprout extracts as natural growth regulators has proven effective in increasing the growth of coffee seedlings in the seedling phase, offering an environmentally friendly and economical alternative for optimizing the growth of coffee seedlings.

Abstract

Agarwood (Aquilaria malaccensis Lamk.) is a highly sought-after non-timber forest product due to its valuable resin used in perfumes, medicines, and cosmetics. However, despite its significant commercial potential, agarwood cultivation in Indonesia remains underdeveloped, particularly in Sumatra. Agarwood seedling propagation can be achieved through land extensification, particularly by utilizing marginal lands. In West Sumatra, most marginal lands consist of ultisol soil, which has very low nutrient content. Therefore, the addition of organic matter and microorganisms is necessary to improve soil health and fertility to support plant growth. This study evaluated the effects of Plant Growth-Promoting Rhizobacteria (PGPR) and NASA Liquid Organic Fertilizer (LOF) on the growth of agarwood seedlings in ultisol soil, which is known for its low fertility and high acidity. The experiment employed a Completely Randomized Design (CRD) with two factors: PGPR (0, 10, 20, 30 ml/L) and NASA LOF (0, 20, 30, 40 ml/L). The results showed that the appropriate application of PGPR and NASA LOF significantly enhanced the growth and development of agarwood seedlings, highlighting their potential in improving agarwood cultivation on less productive ultisol soils. The best combination of PGPR and NASA LOF at a dose of 30 ml/L PGPR and 40 ml/L NASA LOF produced the highest average seedling height (82.34 cm) and the greatest number of leaves (38 leaves per seedling), with all seedlings surviving and meeting the quality standards for transplantation.
