Pest Monitoring Technology For Predicting Pest Attack Intensity Hypothenemus Hampei Ferr. (Coleoptera: Scolytidae) of Arabica Coffee Plant In Enrekang, South of Sulawesi S Sulaeha, N Agus, Hardy, S Sjam, and M Melina Pest and Plant Diseases, Faculty of Agriculture, Hasanuddin University, Makassar 90245, South Sulawesi, Indonesia. Abstract Coffee Berry Borer (Hypothenemus hampei Ferr.) is one of the most serious pests, causing up to 80% yield losses in coffee. Because the Arabica coffee variety is wider than the Arabica coffee variant, the Coffee Berry Borer pest attacks arabica coffee more than robust type in Indonesia. As a result, H. hampei had spread across Indonesia and is now an endemic pest. Population monitoring techniques to reduce pest invasion spread and attack are among the pest management approaches. This study was undertaken to forecast attacks during the harvest season through monitoring the population of H. hampei in Enrekang district, that had not been done earlier. The study conducted in Enrekang district using the weekly observation technique and identifying the sample plants that used a line transect. Plant samples were collected using line transects each 4 meters, with such a total of 30 tree samples observed. The study indicate that pest monitoring technology could determine attack levels in post-peak cropping conditions (high season), with the highest attack intensity of 6.14 percent at the beginning of the observe and also the lowest at 0.54 percent at the end. CBB pests attack based on fruit color, with unripe green fruit getting its most attention compared to red, with a total of 209 green fruits attacked out of a total of 264 fruits. H. Hampei will begin its first attack on young fruit whose endosperm has hardened, and dark green fruit (Fruit Development) aged 1 month which is the most sensitive. The soft tissue of the dark green fruits supports the movement of CBB larvae. Direct monitoring on infection rates will improve in decision making for control measures to reduce population and spread. Crop attack rate will be decreased with monitoring techniques and management systems.

The main factors that determine the quality and price of EBN are color and cleanliness of EBN from the attached swiftlet feathers. The removal of swiftlet feathers in EBN is usually done manually which is destructive to the structure of EBN, reduce the quality and price of EBN, inefficient in terms of time and cost, and ineffective due to human error. The use of serine protease enzyme can degrade swiftlet feathers in EBN non-destructively, environmentally friendly, safe for food, efficient in cost and time, and increase the production of clean EBN. The serine protease enzyme needs to be applied accurately with different doses according to the weight of swiftlet feathers in order to degrade all swiftlet feathers in EBN effectively and efficient in enzyme costs to optimize the profit of clean EBN production. The purpose of this study was to detect the dose of serine protease enzyme in degrading all feathers in EBN according to the uncleaned EBN images using Convolutional Neural Network (CNN). CNN as the main deep learning architecture was used in this study because of its ability to learn image characteristics automatically with high accuracy in the image recognition process. The training accuracy with GoogleNet as the pretrained network of CNN in this study reached 95.35%.

Therefore, land consolidation is needed to enlarging the farmer^s agricultural working land or land tenure which could improve effectiveness and efficiency of the cultivation, empowering farmer^s bargaining position as well as increasing agricultural productivity. In order to support government initiative through food estate programe to achieve self food sufficiency, the most recent innovation which has been introduced was forming a corporate farming or agricultural estate community that could further enhancing and nurturing farmer^s collective work. This initiative has been tested on several agricultural research locations in Indonesia, including Malang Regency, East Java Province, Purbalingga Regency, Central Java and Banyuasin and Musi Banyuasin Regencies in South Sumatera Province, focusing on paddy areas. Nevertheless, land consolidation is still difficult to be accomplished, but the forming of the Paddy or Rice Estate Community is a good start. Then, the solution offered is to set and situated units of land management managed by the Rice Estate Community.

The failure of achieving the national average productivity of 6 ton/ha suggests the need to spur of agricultural revitalization system with intensive cultivation technology. One of the alternatives is intensive technology package that combines using of paddy variety of more than 500 grains/punicle, high-population domino cultivation system, and customizable fertilization system based on the soil quality and production target. Ideally, the production target can be estimated through analyzing the cultivation system used related to population crop density, paddy variety used, and application of the fertilization recommendation system. The low-cost agricultural cultivation system should changing into a high production target and high-profit system through the use of the intensive technology package. Pilot testing results in some demonstration plots and demonstration farms of rice estate communities (in some regencies in East Java, Central Java, West Java and South Sumatera Provinces achieved the expected targets. Majority, the high paddy productivity was achieved, even in some areas exceeded 10 ton/ha, depending on the soil quality, paddy variety used, cultivation pattern system used, and the fertilizer dosage applied.

Prospects of Sterile Insect Techniques for fruit fly control in Indonesia Murni Indarwatmi(a*), Indah Arastuti Nasution(a), Sulaeha Sulaeha(b) a) National Atomic Energy Agency (BATAN), Jakarta, Indonesia b) Faculty of Agriculture, Universitas Hasanudin, Makassar, Indonesia Abstract The Sterile Insect Technique (SIT) is a method of pest control using area-wide inundative releases of sterile insects to reduce reproduction in a field population of the same species. This technique has been successfully applied to control fruit flies, moths, and mosquitoes. The National Nuclear Energy Agency of Indonesia in collaboration with the International Atomic Energy Agency is developing TSM for B. dorsalis and B. carambolae fruit flies. Both of B. dorsalis and B. carambolae are the main fruit fly pests in Indonesia and are quarantine pests for Indonesian fruits to be exported. The working principle of SIT is that field insects are rear in the laboratory, insect irradiated to make them sterile, sterile insects are released into the field to mate with wild insects. The results of the mating of sterile insects with wild insects did not produce offspring so that the field population decreased. The application of SIT in Indonesia is still in the field trial stage. The prospect of applying this technique is very good because this technique has the advantages of being effective in reducing pest populations, species specific so it is safe for non-target insects, environmentally friendly because it reduces the use of insecticides, its compatible with other techniques in integrated area wide control, and increases fruit export opportunities. The future challenge is together with farmers, fruit exporters and the Directorate of Plant Protection of Horticulture, the Ministry of Agriculture implements TSM in a wide area integrated pest control management to reduce yield losses and increase Indonesian fruit exports.

Tentara Pelajar No. 12 Cimanggu - Bogor Bogor 16111 Abstract Potential agroecosystems in terms of area but suboptimal from land productivity are lowland swamps and drylands. The main constraints to maize production in these two agroecosystems are low soil pH and soil nutrients. This obstacle will be more severe if there is a global climate change. Increasing the potential of local maize genetic resources is needed to address these constraints. The review aims to explore the possibility, problems, and efforts to increase the productivity of local maize genetic resources. The review method uses reference studies of different research results, especially those related to local corn varieties, research technology, and utilization in breeding programs. The results of a review of various references show that local maize productivity based on the implementation of existing technology is primarily determined by genetic, environmental, and management factors. Constraints of corn production in swampland and dryland will become potential by increasing local corn^s existence. Increasing local maize^s existence is used as a gene donor in creating stress-tolerant varieties (low soil pH and nutrients, inundation, drought, pests, and diseases). Increasing local maize^s existence is used as a gene donor in creating stress-tolerant varieties (low soil pH and nutrients, inundation, drought, pests, and diseases). The increased opportunity for local corn technology adoption can be done by refocusing research that explicitly uses tolerance and efficiency parameters.

This study aimed to identify the problem of orange on the field and to know the prospect of sweet orange agribusiness. The research was conducted at three centers of development of the orange Selayar, namely Bontomatene, Bontosikuyu, Bontoharu districts. Data collection was carried out using survey methods and interviews with citrus farmers and related agencies. The data that has been obtained are analyzed by qualitative and quantitative descriptive methods. To analyze the income of farmers from citrus farming was calculated by the ratio of revenue and costs (R/C ratio). The results showed that the area of potential development of Selayar oranges reached 6,750 ha, but until 2019 the area planted was only 1,935 ha with a population of 779,761 trees. Strangely, planting is expanding, but the annual production is decreasing. Various factors include:, the high attack of various pests especially blendok disease and CVPD, availability of water during dry season, procurement of seedlings with rootstock Selayar replacing Japanese citrone and provision seedling without indexing systemic diseases. The net income level of citrus farmers in Selayar Regency is on average only IDR 70,000,000/ha/year or 17.5% of the potential land that must be obtained, whereas if cultivated properly can produce IDR 400,000,000/ha/year. The prospect of sweet orange agribusiness is very feasible to be undertaken if properly cultivated with the level of income can reach IDR 97,000,000 in the 5th year and IDR 457,950.0000 in the 12th year with RC ratio of 5.2 and 21.8.

Techniques For Controlling Spodoptera Exigua On Shallots By Using Trap Lights Fatahuddin, Ahdin Gassa, Sulaeha Sulaeha and Sophia Pest and Plant Diseases, Faculty of Agriculture, Hasanuddin University, Makassar 90245, South Sulawesi, Indonesia. Abstract Shallots are one of the horticultural crops that are widely cultivated in certain areas in South Sulawesi. One of the limiting factors in efforts to increase the production of shallots is the disturbance of plant pests and plant diseases. Spodoptera exigua is a major pest on shallot plants. This pest was found attacking shallot plants from the time the plants appeared on the ground until harvest. The yield loss of shallots can reach 70% to 100% in the dry season if it is not controlled using pesticides. This study aims to determine the percentage of damage to shallot plants due to Spodoptera exiqua attack by using light traps. This research was carried out on land owned by farmers from August to October 2020. In this study, paired T-test was used with two treatments, namely P0: shallot plantation plots without trap lights, P1: shallot plantation plots using light traps. Observation parameters were the percentage of leaf damage of shallots and production. The results showed that the average percentage of leaf damage of shallots with the use of trap lights was lower than without using trap lights. The production of wet bulbs of shallots in the lamp trap treatment was 7.29 tons/ha and higher than the treatment without lamp traps, which was 4.95 tons/ha.
