Abstract

Indonesia's export value has decreased while Indonesia's coffee production has increased. Competition in seizing the current market in order to increase and maintain the quantity or volume of exports in the international market. The increase is to be able to compete in the international market to be able to excel with other countries as well as various challenges faced and in an effort to increase the volume and value of coffee commodity exports with competitiveness and demand for coffee in the international market. Researchers aim to analyse the export of HS 0901 coffee commodities to the largest destination countries exporting to Egypt , Malaysia, Italy and Japan, although in this case the volume of coffee exports has decreased. This research is a time series secondary data collection based on 2018 to 2023. The export data studied is the export of coffee commodities with the code (Harmonized System) HS 0901 to Malaysia, Japan, Egypt and Italy using Revealed Comparative Advantage Analysis and Trade Specialisation Index. The results show that HS 0901 coffee has strong competitiveness comparatively in Malaysia, Egpy and Japan. While in Italy the RCA value does not have comparative competitiveness. In ISP Indonesia is at the maturity stage by producing an average ISP Value of 1.

Abstract

This research aims to determine the durian breeding business and analyze the feasibility of a certified durian (Durio zibethinus) plant nursery business in breeders assisted by UPTD Building Horticulture Parent Seeds. This research was carried out for 1 (one) month using a census method among captive farmers. Feasibility Analysis of Certified Durian (Durio zibethinus) Plant Breeding Business at the Breeder Assisted by UPTD Horticulture Parent Seeds Gedung Johor, shows that the average total production cost is IDR 174,451,854, while the revenue is IDR. 308,706,641 and income of Rp. 134,254,786 To find out whether the business is feasible or not, it can be used to analyze the business by calculating production costs, calculating revenue and analyzing the results then calculating the results using the R/C Ratio and B/C Ratio methods. The research results show that the R/C Ratio value is 1.58 and the B/C Ratio value is 0.58, production productivity is greater than the production BEP, namely 13,891 and the price received by the nursery owner is greater than the BEP price, namely Rp. 5,550. From the research results, it was concluded that the durian breeding business was profitable and worth pursuing. In developing the durian agribusiness, the support of the availability of quality seeds from superior varieties is critical to success. The reality in the field shows that the availability of quality seeds is still an obstacle, so many farmers still use random seeds.

Abstract

Durian, a superior product in North Sumatra, has high economic value and market opportunities. In an effort to develop a durian agribusiness business, the support for the availability of certified quality seeds from superior varieties greatly determines its success. The research aims to develop a nursery business model that is both economical and profitable, catering to the demand for certified quality seedlings and promoting sustainable agricultural development. The study employs a quantitative descriptive method to explain the nursery business's economic feasibility and ensure the sustainability of the provision of certified quality durian seeds. The research was carried out between March and June 2024 in three districts/cities, specifically Binjai, Langkat, and Deli Serdang, where the UPTD (Regional Technical Implementation Unit) of the Horticulture Main Seed Center (BBI) of the Food Security Office of Food Crops and Horticulture of North Sumatra Province operates a farming farm for the propagation of superior durian seeds. The purposive method was used to select a sample of 50 durian seed breeders, with assistance from the UPTD BBI. The data analysis method uses Structure Equition Modeling (SEM) to build the model. The results of the study show that business performance has an effect on local fruit development, the nursery business model has an effect on business performance, and certification has an effect on business performance. Overall, the results of this study show that to ensure the development of local fruits, nursery businesses must develop a business strategy that meets quality and quantity standards so that they can ensure the sustainability of the supply chain from producers to consumers.

Abstract

A study of the role of extension workers in the implementation of OPT management in the context of sustainable agricultural ecosystems and its relation to lowland rice productivity in Asahan Regency is very relevant to carry out. Analyzing the impact of the role of extension workers on the use of different pest management techniques in encouraging the adoption of sustainable practices will provide valuable insights for the development of more sustainable agriculture, reducing environmental and health risks, and increasing farmer productivity and welfare. The research method used is "Field Research" with a "Case Study" approach. The research results show that lowland rice farmers in Asahan Regency have implemented various components of sustainable management of Plant Pest Organisms (OPT) using various approaches. They use physical, mechanical, technical culture, resistant varieties, biological control techniques, as well as control with rules and regulations to face the challenges of plant pests and diseases. Through a combination of these techniques, farmers strive to achieve a balance between the effectiveness of pest control and their positive impact on the environment Keywords: extension agent, OPT, sustainability INTISARIKajian tentang peran penyuluh terhadap implementasi pengelolaan OPT dalam rangka keberlanjutan ekosistem pertanian serta kaitannya dengan produktivitas padi sawah di Kabupaten Asahan sangat relevan untuk dilakukan.

Abstract

Rice Blast has been known as the main disease on paddy which has high severity leading to economic loss. Exploring rice resistance can be an effective way to improve productivity and prosperity toward this staple crop. This study aims to determine several local varieties which have potential for productions and resistances. This study used factorial randomized block design (RBD) consisting of 2 factors including plant spacing (25 x 25 cm; 25 x 30 cm; 25 x 40 cm); Upland rice variety MSP 17, Sigambiri Merah, Hamparan Perak and Kambiri Lumat. The results of the study reveal that variety has a significant effect on disease intensity especially Sigambiri Merah but not on Kembiri Lumat. However, there is no significant effect of spacing on blast intensity except in grain weight. Conclusion of this research was the varieties (V) selection of red upland rice is the best strategy to improve rice resistance toward blast disease. Keywords:  Disease density, Paddy, Staple Crop.

Abstract

Typhonium flagelliforme or known as rat taro is a herbaceous plant that belongs to the taro tribe. The results of the phytochemical analysis of the leaves and tuber extracts of rat taro are known to contain secondary metabolite compounds belonging to the class of flavonoids, alkaloids, triterpenoids, steroids, saponins, and tannins which act as antimicrobials. This study aims to determine the effectiveness of leaf, stem and tuber extracts of rat taro (Typhonium flagelliforme (Lodd)) as a biofungicide against the cause of leaf fall (Pestalotiopsis sp.) on rubber plants (Hevea brasiliensis). Leaf samples came from rubber plants at PTPN III Karet Sei Putih, Galan District, Deli Serdang Regency, North Sumatra. Pestalotiopsis sp. was isolated from plant parts showing leaf fall symptoms. Pieces of rubber leaves infected with Pestalotiopsis sp. was grown on PDA media in a petri dish and incubated for ±7 days at room temperature 26–28oC. After incubation, microscopic identification of the conidia of the fungus was carried out. In vitro test of the inhibition power of extracts of leaves, stems and tubers of rat taro against the fungus Pestalotiopsis sp. was carried out in a petri dish using the fungus culture method. The results of the phytochemical screening showed that the leaf, stem and tuber extracts of rat taro contained chemical compounds of flavonoids, tannins, saponins, alkoloids, and steroids/triterpenoids. The results showed that the leaves, stems and tuber extracts of rat taro (T. flagelliforme L.) have potential as biofungicides, K13 treatment of tuber extract of rat taro (Typhonium flagelliforme L.) 9% was the best treatment which could inhibit the growth of Pestalotiopsis sp.
