Abstract

This study was conducted to evaluate the potency of Brucea javanica (melur) for controlling two species ofcrucifer pests, i.e. Crocidolomia pavonana and Plutella xylostella. Melur fruits, twigs, and leaves were extracteddirectly with methanol or sequentially with hexane, ethyl acetate, and methanol. The most active extract was thenfractionated by preparative layer chromatography using hexane, mixtures of ethyl acetate and methanol, andmethanol as eluents. The most active fraction was formulated as EC (emulsifiable concentrate) and WP (wettablepowder) formulations, and tested for their toxicity and antifeedant effect against C. pavonana and P. xylostellalarvae. The results showed that methanol extract of melur fruits was more active than that of twigs and leaves.Fractionation of methanol extract of melur fruits yielded an active fraction which was eluted with ethyl acetate-methanol 9:1. EC and WP formulations of melur fruits were active against C. pavonana larvae with LC50 of 0.39%and 0.21%, respectively. The same formulations were also active against P. xylostella larvae with LC50 of 0.31% and0.54%, respectively. In no-choice tests, the antifeedant effect of the EC formulation on C. pavonana larvae (feedinginhibition [FI]: 70.9%-97.5%) was higher than on P. xylostella larvae (FI: 52.2%-83.9%), but the antifeedant effect ofthe WP formulation on the two species was relatively the same. In a choice test, the EC formulation at LC 85completely inhibited feeding by C. pavonana larvae (FI: 100%).

Abstract

West Sumatra is a province where the average population works as a farmer. Rice production in West Sumatra is quite high, reaching 55,532 tons per year. However, farmers experience difficulties in dealing with pest attacks, one of which is bird pest. Bird pest causes a loss of yield of 30% and even 100% at severe levels of attack, and in other cerelia plants capable of causing yield loss to reach 67%. As a result of high yield loss, it is necessary to control bird pests. However, control of bird pests is not the same as other pests that can be controlled practically using pesticides due to mobile pests that are mobile or active. t present farmers still use mechanical control in Sumatra called 'Manggaro'. Where farmers wait for their fields and fields during the filling phase until harvest. This mechanical control takes the time of the farmer to drive the arrival of bird pests. Based on these problems, it takes a business and technology that can be used to drive birds without the need to be monitored by farmers, save time and be more efficient in controlling and can be used in the long run. The proposed research activities included the installation of automatic bird removal equipment with a body heat detection system and sound source swinging motor in the paddy fields located at the Unand Limau Manis campus. Observations made were the results of rice production on the 3 treatments given, namely the use of automatic pest removal tools,

Abstract

The selling price of citronella oil is very low, namely 140,000 Rupiahs/liter and a low yield of 0.5-1.2% of the total refined raw materials are serious problems for citronella farmers in general and the Laiang Jaya farmer group, Solok, West Sumatra. In the distillation process, a large amount of liquid waste (hydrosol) is produced as much as 50%-60%. Hydrosol is an essential oil emulsion that is bound to water and still contains 0.02% essential oil. Insecticidal activity can be increased by adding plant material that has neurotoxic properties such as forest betel (Piper aduncum), which is easily found in forests and vacant lands in the surround of farmers' locations. Isolation of the active ingredients of forest betel is carried out with a distillation system so that it is not difficult for farmers to produce and surely increase their income through alternative use of distilled equipment when it useless. The purpose of this activity is to transfer knowledge related to the utilization of citronella waste into useful products such as raw materials for botanical insecticides. The methods used in this activity are education, workshops, training, mentoring and evaluation of activities. This activity has a positive impact on farmer groups. With this activity, farmer groups understand the importance of technology in product development, produced a prototype in the form of a botanical insecticide from citronella waste. As well as gaining knowledge related to branding and packaging of other citronella oil derivative products that are different from the usual ones.

Abstract

Petani sangat mengandalkan insektisida sintetik dalam upaya pengendalian hama. Penggunaan insektisida sintetik yang tidak bijaksana dapat menyebabkan kerusakan lingkungan yang ditandai dengan musnahnya mikro organisme tanah, matinya musuh alami, dan matinya organisme bukan sasaran lainnya. Selain itu dampak negatif residu pestisida pada produk pertanian dapat menyebabkan gangguan kesehatan pada manusia yang mengkonsumsi produk yang terkontaminasi residu pestisida. Pengendalian hama alternatif yang ramah lingkungan sangat dibutuhkan dalam proses budidaya tanaman, diantaranya adalah insektisida botani. Upaya mengurangi ketergantungan petani terhadap insektisida sintetik dapat dilakukan dengan menjadikan petani sebagai produsen insektisida dan bukan hanya sebagai konsumen. Insektisida botani dari bahan tumbuhan yang ada di sekitar tempat bercocok tanam dapat digunakan sebagai tindakan pencegahan (preventif) dari serangan hama. Piper aduncum atau yang disebut sirih hutan dan Tephrosia vogelii atau disebut kacang babi banyak ditemukan di lahan pertanian produktif Alahan Panjang, Sumatera Barat. Campuran dua jenis bahan ini dengan perbandingan 2:1 diketahui dapat mengendalikan hama dari golongan Lepidoptera yang menyerang sayuran. Sosialisasi penggunaan di tingkat petani, latihan penyiapan bahan tanaman dan pembuatan larutan semprot dengan konsentrasi 5%, perlu dilakukan agar pengendalian hama efektif dan efisien. Manfaat kegiatan ini dapat membantu petani dalam mengendalikan serangan hama pada tanaman budidaya, mengurangi penggunaan insektisida sintetik, menghemat biaya produksi dan secara tidak langsung meningkatkan pendapatan petani.

Abstract

The purpose of this research was to evaluate the safety of mixture formulations of Tephrosia vogelii and Piper aduncum at various storage temperatures and their insecticidal activity against C. pavonana larvae. Formulations were made from T. vogelii and P. aduncum (1:5) in emulsifiable concentrate (EC) and wettable powder (WP) form. Both formulations have strong insecticidal activity against C. pavonana. This research used a randomized completed design in different temperature treatments. Insecticidal activity of formulations after storage was tested against C. pavonana. The treatments were done using deep leaf method in 5 concentrations and 5 replications. The results showed that LC95 value of EC formulation after storage at condition: below 4°C, room temperature, and 40°C were 0.19%, 0.34% and 0.21% respectively. Based on LC95 value of EC formulation from each treatment, indicated that EC formulation after storage could hold insecticidal activity as good as insecticidal activity before storage due to LC95 value after storage relatively lower than LC95 value before storage (0.35%). In the contrary, WP formulation activity was significantly decreased in all treatments compared to WP formulation activity before storage based on LC95 value.

Abstract

Sorghum is an adaptive plant, can grow optimally on dry and acid soil and is resistant to marginal conditions (drought, salinity, and acid soils). This plant has benefits from carbohydrates to replace rice and can be processed into other derivative products. People consume sorghum that is processed traditionally, among others, made porridge or steamed and enjoyed immediately. Also, with proper processing, it can make sorghum potential health functional food. This activity aims to improve the economy of the surrounding community by providing knowledge and information related to sorghum processing and cultivation. Activities were carried out in the form of counseling, training, and mentoring. At the end of the program, a technology transfer can increase people's knowledge and income in Nagari Rambat. The activity results found that Jorong Pabalutan and Dusun Ladang Laweh were located in Nagari Rambat, Rambat District, Tanah Datar Regency, West Sumatra. Nagari Rambat has 1,550 families, the majority of whom are rice farmers in the fields, tapping rubber. The area of ​​rice fields in Nagari Rambat is around 27,442 hectares. The general condition faced by farmers is irrigation problems; farmers only plant rice in the fields twice a year, even only once a year. This is because the propagation is a rain shadow area. One of the efforts to fill the void of land during the dry season is by cultivating sorghum. Furthermore, the Sepakat farmer groups' survey results and the Kuta Bali farmer groups show a strong desire to obtain a transfer of knowledge and technology related to proper and correct sorghum cultivation.

Abstract

Sorghum farmers in West Sumatra, especially Padang Pariaman, have low knowledge of sorghum varieties in plants. This is because sorghum relatively new food commodity cultivated in this area. The three varieties of sorghum that are often grown by farmers are numbu, Super 1, and red varieties, which differ in morphology, texture, and taste. The general procedure for harvesting sorghum begins with cutting panicles, drying them in the sun, threshing them, and drying them again until the moisture content reaches 12%. Then the sorghum seeds are crushed using a sosoh machine so that the tannin in the outer skin layer is lost. After going through the filling process, sorghum rice is produced, can be consumed directly by cooking it into porridge, cooked like rice, or mixed with rice (rasgum). Sorghum rice can also be ground into flour and used as a base for making various types of food. The community service team has carried out a chemical analysis of sorghum flour. There are amylose and amylopectin analysis, starch content analysis, starch gelatinization profile, and reducing sugar. The objective of this activity is to transfer knowledge and technology related to sorghum rice and sorghum flour as raw materials for food processing. From the data obtained, known that red sorghum has the best performance as raw material for wet-processed food, while Numbu and Super 1 are suitable as raw materials for dry processed food.
