Abstract

Crossing is one technique to expand the genetic diversity. The research objective was to estimate the genetic variability, heritability and number of genes controlling characters tomato yield and yield component in the F2 population crosses TMU-1 xTMU-2 at the low altitude. The research was conducted from April to October 2016 in Kandang Limun, Bengkulu city with a height of 10 m (low altitude). Estimates of genetic variability, heritability and number of genes controlling the yield character is determined based on the mean and variance in the population. The results showed all of the characters that were tested had a number of genes controlling the character as much as one gene. Characters are controlled by a single gene is expected fixation genes to be rapid in some early cycles of selection. Eight characters had a high heritability. Each character and heritability is flowering day (52.90%), the number of fruits per plant (92.99%), fruits length (77.10%), fruits diameter (71.76%), the number of locul fruits (85.68%), thick flesh (73.05%), total soluble solids (89.77%) and fruit weight per plant (65.19%). Keywords: diversity, heritability, low altitude, number of genes group, yield component

Abstract

In Indonesia, cocoa (Theobromae cacao L.) is one of the nations third-largest contributor of foreign exchange, but the problem that arises on cocoa plantations in Indonesia is the difficulty of obtaining a healthy cacao seedlings in large numbers for the rejuvenation of cocoa cropping. One of methods to obtained healthy cacao seedlings with good performance in large numbers is application of arbuscular mycorrhizal fungi (AMF). This researches aims to observe the role of AMF mass production in the zeolite medium on the growth and leaf spot intensity of cocoa seedlings. The researches were conducted at the field condition in Sleman, Yogyakarta and Mycological Laboratory of the Faculty of Agriculture and the Laboratory of Phytochemistry, Faculty of Pharmacy, University of Gadjah Mada, Yogyakarta. The main ingredient of the study is AMF mass production in the zeolite medium. The observed variables were the growth of cocoa seedlings, the number of spores from each location, the cocoa seedlings height, leaf numbers, wet weight, dry weight and root length of seedlings of cocoa, symptom and intensity of leaf spot disease, detection of salicylic acid (SA) manually and TLC methods, and environmental factors which include: temperature, humidity and light intensity. The results indicated that the only real difference in the height and number of leaves, whereas other variables were not significantly different. This is because AMF spores from all locations are derived from the similarity of the two genera, namely Glomus sp., and Gigaspora sp., and was almost the same amount. Leaf spot disease symptoms appeared only a few of the cocoa seedlings, but more due to unfavorable environmental factors and conditions are weak pathogens. Plant defense responses had not been established because the salicylic acid content in leaves of cocoa seedlings at 12 weeks has not been detected.

Abstract

[DETECTION OF TUNGRO VIRUS ON RICE IN BENGKULU]. Several types of viruses have been reported to infect rice plants in Indonesia, including tungro, dwarf grass, and empty dwarfs. The spread of tungro in Indonesia in the beginning was only limited to certain regions in South Sulawesi, South Kalimantan, West Nusa Tenggara and North Sulawesi, but later it expanded to East Java, Central Java and Yogyakarta. In this study a tungro disease survey was conducted in several areas in Bengkulu Province. Virus detection is done by Loop-medated isothermal amplification (LAMP). Observations in the field showed that there were typical symptoms of tungro infection in rice plants, namely orange leaves starting from leaves to 2 and 3, little tillers, stunted plant growth. The results of detection with Lamp-PCR showed rice samples from the district Pondok Kelapa Kab Bengkulu Tengah is positively infected with tungro virus.

Abstract

This activity aims to foster the farmers who are members of Gapoktan Seroja I Kandang Limun, Bengkulu to initiate oyster mushroom cultivationas one of the prospective agribusinesses in Bengkulu. This business was chosen due to the fungus growing medium are available in huge quantities and being waste around Kandang Limun. Further, Oyster mushroom demand and price  are high. This event is a program of Ipteks bagi Masyarakat (IBM) in collaboration with the Lembaga Pengabdian Masyarakat (LPM). Training activities include the cultivation, manufacture kumbung measuring 3x4m which capacity of 2000 baglogs, baglog manufacture, sterilization baglog, inoculation, incubation for 3-6 weeks until the harvesting and marketing. Gapoktan Seroja I have been able to make ± 1500 baglog and have been able to produce white oyster mushroom ± 5 to10 kg per day. Fresh mushrooms sold at Rp. 20,000-24.000/kg. With good management and sustainable production, the oyster mushroom cultivation can be one of the prospective agribusiness for Gapoktan Seroja I Kandang Limun, Bengkulu.Keywords: Oyster Mushroom Cultivation, Agribusiness.

Abstract

This study aims to describe how the implementation of incentives as stipulated in Government Regulation No. 12 of 2012 concerning the protection of agricultural land incentives sustainable food in the Dusun Besar Lake area of the city of Bengkulu. This research is a descriptive study with a qualitative approach. Informants determination use purposive sampling. Data collection techniques consist of observation, interviews and discussions as well as documentation. Data analysis are conducted by inductively starting from data collection, data reduction, data presentation and data verification. Based on the results of a couple of aspects studied, namely communication, resources, disposition, and bureaucratic structures, further seen from the form of the provision of incentives in the form of : agricultural infrastructure development has not been run, the financing of research and development of improved varieties of seeds and no ease of access to information and existing technology (extension), the provision of production facilities, guarantee certificate issuance of land rights on agricultural land are not sustainable food and / or rewards for high achievers existing farmers, government programs. It was concluded that the implementation of the Regulation no 12tahun 2012 in incentives for farmers land owners in the Dusun Besar Lake area of the city of Bengkulu is not already running. While the constraints faced by the lack of regulations governing the area of land protection sustainable food. Therefore, intensive provision for sustainable food future land owners should be budgeted and city government programs through agencies or institutions concerned.Keywords: implementation, incentive, PP, Agricultural land
