Publisher : Warmadewa University Press

Brown Planthopper (BPH), Nilaparvata lugens Stal (Hemiptera: Delpachidae) is the important pest of rice. The infestation of BPH reduced the rice yield on rice producer countries in Asia. In Indonesia, the area of BPH infestation frequently fluctuated over the year. BPH directly caused hopper burn and also vector of rice grassy stunt virus (RGSV) and rice ragged stunt virus (RRSV). This study aimed to evaluate the resistance of some rice varieties to different BPH population in Java. Three BPH populations collected from Karawang (West Java), Pekalongan (Central Java) and Kendal (Central Java) were used in this study. The rice resistance was evaluated by conducting honeydew test. There were eight rice varieties tested i.e Sembada 168, Ciherang, Inpari 32, Inpari 33, IR 64, TN1, Ratu Heenati and PTB 33 with five replications. A number of 200 female adults (five females per plot) were starved for 2 hours before inserting to pot containing one seedling. The BPH adults were allowed to feed 40-day-old plants for 48 hours. The area of honeydew excreted by BPH was measured using software Image J. We used analysis of variance (ANOVA) and cluster analysis with ward method and similarity index of Euclidean distance to analyze the rice resistance to BPH. The study indicated three groups of rice resistance level. The variety of Sembada 168 and TN1 were susceptible to BPH. Variety of Ciherang, Inpari 32, Inpari 33 and IR 64 were moderately resistant to BPH. However, PTB 33 and Ratu Heenati were strongly resistant to BPH population of Java.

Yellowing diseases is one types of plant diseases which are found in some of the centers of cultivation of yard long bean in Bali. The spread of yellowing diseases caused the presence of vector insects, such as whiteflies and alternative host plants, such as weeds and other crops. This problem is then examined through statistical modeling in order to determine the pattern of the relationship between the incidence of yellowing disease with the populations of whiteflies and the alternative host plants. Collection of data on the yellowing disease incidences, the abundance of whiteflies, and the existence of alternative host plants was done through a direct observation in 100 farmer fields in several centers of cultivation of yard long beans in Bali. Determination of the best mathematical model was performed by linear regression analysis with ordinary least squares method. The results indicated that the best models for the relationship between the incidence of yellowing disease (KPK) with the population of whiteflies (KB) as well as the alternative host plants of yellowing were as follows: KPK = 1,2265 KB0,9872 TIAK1,0936 (R2 = 98,43 %; P-value = 0,000). The incidence of yellowing disease was highly significant positively correlated with the population of whiteflies and yellowing symptomatic alternative host plants. The existence of alternative host plants around the field was very decisive in triggering the emergence of yellow virus disease in the crop.

The development of subak as a tourist attraction will be in line with the development of Balinese cultural tourism, considering that both are developed based on Balinese culture. This is an effort to maintain the sustainability of subak while controlling the conversion of paddy fields and supporting environmental sustainability. Today's tourists prefer to see beautiful scenery. Agrotourism is one type of tourism that utilizes agricultural business as a tourist attraction. One of the efforts made to continue to develop tourism but still maintain the existence of subak itself is to combine these two things into a new tourist attraction. The attraction that can be developed by combining tourism with agriculture is through the concept of agrotourism. Agrotourism is a tourism development that offers farmer activities in the fields as a tourist attraction. Not only the activities, but the use of agricultural products can also be used as agro-tourism-based tourism products. This research was conducted with the following objectives (1) How is the participation of farmers in the development of agro-tourism and (2) the factors that influence the participation of farmers on the development of agro-tourism. This research was conducted in Subak Jatiluwih, Penebel District, Tabanan Regency. The location of this research was determined purposively on the basis of the consideration that Jatiluwih Subak is one of the subaks targeted for agro-tourism development. The number of samples in Subak Jatiluwih is 199 people. The highest farmer participation is in the 80.2% agro-tourism development planning.

Abstract Oil palm plantations in Aceh , especially in Bireuen, are generally planted on red-yellow podzolic soil types. Arbuscular mycorrhizal fungi (AMF) are fungi who are symbiotically associated with 97% of plant species. This study aims to identify the type and population of mycorrhizal spores from oil palm rhizosphere soil samples using culture trapping techniques (maize, sorghum, kudzu). This research was carried out in a greenhouse and Experimental Field, Faculty of Agriculture, Islamic National University of Indonesia, Bireuen, Aceh. Isolation, identification and observation of AMF colonization on plant roots was carried out at the Laboratory of Soil Biology, Faculty of Agriculture, Syiah Kuala University. The parameters included the number of arbuscular mycorrhizal fungi spores and the percentage of root colonization using the trapping culture method. The trapping culture method used 50 g of soil samples on oil palm rhizosphere which aged 5 months, 7 years, 9 years and 12 years. The results showed that the most dominant mycorrhizae found was the Glomus type. The mycorrhizae spores types found in the trapping culture were Glomus, Acaulospora and Gigaspora. The host plant that produced the most AMF spores was sorghum, while the highest AMF colonization of the three host plants was found in the roots of maize plants (78%) with very high criteria.

Publisher : Warmadewa University Press

Endophytic bacteria have many benefits, including increasing plant growth by producing phytohormones, increasing the production of mineral absorption, nitrogen fixation, reducing damage due to weather changes and increasing plant resistance to disease. Based on the above, it is necessary to select endophytic bacteria from various plants to be used as biocontrol agents. This study aims to obtain endophytic bacterial isolates that have the potential as biocontrol agents and plant growth supporters from bamboo shoots, Gamal, Tulsi, Lotus, and Alamanda. This research method includes sampling, endophytic bacteria isolation, hypersensitive, hemolysis, phosphate solvent, chitinolytic, proteolytic, and antagonist tests. Isolation of endophytic bacteria in 5 plants using 22 plant parts had a diversity of isolates. The isolated plant parts produced 1 to 7 isolates that had different morphology. The total isolates obtained were 59 isolates. In antagonistic observations, there was one isolate of endophytic bacteria that showed a clear zone when tested together with S. rolfsii, namely the isolate with code A24 from allamanda flower. From the data obtained, it is known that the endophytic bacterial isolates had an effect on inhibiting the growth of the pathogenic fungus S. roflsii, the endophytic bacterial isolates Consortium, A21 and the endophytic bacterial isolates A22 had no incidence of disease, while the bacterial isolates T00 (Bx) with an average disease incidence of 40% and 30% disease intensity. Meanwhile isolates A23, A24 and A25 had an average disease incidence ranging from 13.3%-26.6%, while controls had the highest disease incidence, namely 53.3% and disease intensity 66.6%.

The community widely uses the demand for livestock products such as meat because they have good taste and high nutritional content. One source of meat is quail meat. Quail meat has a high nutritional value and is not inferior to other poultry. Quail (Coturnix coturnix japonica) is one of the poultry commodities that has a role in producing animal protein. The purpose of this study was to determine the effect of giving fermented rice bran in the ratio to the weight and percentage of carcasses as well as the weight and percentage of non-carcass male quail aged seven weeks and to determine the level of giving fermented rice bran in the diet of male quail to the best weight and percentage of carcasses and weight and percentage of non-carcass male quail aged seven weeks. The study was conducted using a completely randomized design (CRD) with five treatments and three replications. Each replication consisted of 3 male quail so that the number of male quails used was 45. The treatments were applied as follows, rations with unfermented rice bran 20% and rations with fermented rice bran 5%, 10%, 15%, and 20%. Parameters observed were slaughter weight, carcass weight, non-carcass weight, carcass percentage, and non-carcass percentage. The data obtained were analyzed for variance. If there are significantly different results (P <0.05) between treatments, Duncan's smallest total distance test is carried out. The study results show that the administration of fermented rice bran in the male quail aged seven weeks showed no significant difference (P>0.05) on cut weight, carcass weight, non-carcass weight, carcass percentage, and non-carcass percentage. Based on the results of this study, it can be suggested in making male quail rations to use fermented rice bran to a level of 15% because it can increase the protein content of the ration and can increase slaughter weight, carcass weight, and carcass percentage as well as in rice bran fermentation it is necessary to use another fermenter so that protein rice bran becomes higher so that the protein ration increases and is also expected to reduce the crude fiber content of the ration

One of the high-quality processed vegetable food ingredients is tofu. Tofu is made from processed soy milk with a thick texture and molded according to the right nutritional amount. White tofu is the most popular of the various forms of tofu available. Today, tofu producers have taken manipulative actions to anticipate production losses by including preservatives in the mix of ingredients used to make tofu. Most of the tofu production centers provide additional ingredients in the form of preservatives such as formalin to reduce losses from damage to the tofu they produce. The presence or absence of formalin in food can be detected using a unique component found in dragon fruit peel called anthocyanins. The methodology applied in this research is a simple and direct one, with primary data collected in the form of testing samples of white tofu collected from numerous traditional markets in the Banten area (up to ten samples). The aim of the research is to identify formalin in white tofu discovered in numerous traditional markets in Banten using natural component extracts, including dragon fruit peel extract. The results stated that there were two positive samples containing formalin and eight negative samples; the presence of formalin in tofu was indicated by a red color on the tissue. Sellers or customers can detect formalin simply by utilizing dragon fruit, allowing them to avoid formin which is harmful to health, with a simple and low-cost method.
