Abstract

Humayra Windayani Rangkuti, Identification of Fruit Flies (Diptera: Tephritidae) in Several Districts in North Sumatra Province. Supervised by Prof. Dr. Ir. Nur Hayati, MP and Dr. Ir. Rahmad Setia Budi, M.Sc. Fruit flies (Diptera: Tephritidae) are one of the economically important pests that attract world attention. Fruit flies are generally polyphagous with a wide host range. The presence of fruit flies is a limiting factor for the export of agricultural products, especially fruits and vegetables. Fruits infested with fruit flies will rot and their growth will become abnormal. The damage caused can reach 90%-100%. Sampling of fruit flies using the collection method of trapping using a lure or attractant Methyl eugenol (ME). The study was conducted in several districts in the North Sumatra Region. Fruit flies were identified at the Integrated Laboratory of the North Sumatra Animal, Fish, and Plant Quarantine Center (BBKHIT Sumut). The research was conducted from May to December 2024. The results of the trap installation found 8 species of fruit flies of the genus Bactrocera, subgenus Bactrocera and Zeugodacus with the names of the species found being B. carambolae, B. dorsalis, B. albistrigata, B. (Zeugodacus) tau, B. umbrosa, B. (Z.) caudata, B. raiensis, B. verbasifolie, B. (Z.) cucurbitae. Information on species and status of fruit flies in North Sumatra can be used as a reference in anticipating the spread of fruit flies and how to control them on agricultural products with high economic value. Making a list of pest species (pest list) and description of morphological characteristics of OPT, especially fruit flies, is important in trade negotiations. One of the important roles of quarantine is to prevent the entry and exit of OPT/OPTK including fruit flies from one country to another or from one area to another within the country, or out of the territory of the Republic of Indonesia through local and international trade activities.

Abstract

Prolonged seed dormancy is an obstacle in the provision of quality seedlings. Therefore, this study was conducted to accelerate the germination process of Arenga pinnata Merr. seeds through various treatments. This study aims to evaluate the response of chemical, physical, and organic dormancy breaking on the growth and development of Arenga pinnata Merr. seeds. The method used was a Non-Factorial Complete Randomized Design with seven treatments: seed soaking in 3% H₂SO₄ solution (6 hours), 0.5% KNO₃ (24 hours), 3% HCl (6 hours), sanding (sandpaper), 100% red onion extract (24 hours), 100% palm sap (24 hours), and 100% coconut water (24 hours). The results showed that seed soaking in 3% HCl or sandpaper abrasion yielded the best results in terms of germination rate, although there was no statistically significant effect; these treatments also successfully reduced the dormancy period of palm seeds. Additionally, soaking with 100% palm sap produced the tallest plants at 8 MST and 12 MST. This study is expected to provide useful information for the development of more efficient and practical palm seedling propagation technology.

Abstract

This study aims to determine the effect of organic compost fertilizer and planting distance on the growth and production of soybean plants. This study uses a randomized block design (RBD) factorial with two treatment factors, namely compost fertilizer and planting distance. The first factor, compost fertilizer, consists of five levels: S0 = No treatment, S1 = 75% inorganic NPK fertilizer + 25% organic compost fertilizer, S2 = 50% inorganic NPK fertilizer + 50% organic compost fertilizer, S3 = 25% inorganic NPK fertilizer + 75% compost organic fertilizer, S4 = 100% compost organic fertilizer. The second factor is planting distance, which consists of three levels: J1 = 20 cm x 30 cm planting distance, J2 = 20 cm x 40 cm planting distance, J3 = 25 cm x 40 cm planting distance. The observed parameters were plant height, leaf chlorophyll content, root nodule count, pod count, filled pod count, empty pod count, weight of 100 seeds, seed yield per plot, wet pod weight, and dry pod weight. The results of the study indicate that the application of compost fertilizer has a significant effect on soybean plant height, leaf chlorophyll content, and root nodule count. Planting distance has a significant effect on empty pod weight, 100-seed weight, and dry pod weight. The interaction between compost fertilizer and plant spacing had no significant effect on plant height, leaf chlorophyll content, root nodule number, pod number, filled pod number, empty pod number, 100-seed weight, seed yield per plot, wet husk weight, and dry husk weight.
