Processed soybeans such as tempeh and tofu are some of the foods that the people of Indonesia favour. The Tempe and Tofu processing factory produce tofu with the essential soybean ingredients as much as 17 kg every day. The tofu production process starts from soybean immersion, grinding, boiling, filtering, compaction, moulding, cutting, to frying tofu. Production activities from the tofu industry will certainly produce solid and wastewater. These wastes can have a negative impact on the environment. Therefore, the waste must be managed and treated correctly to create an environmentally friendly industry and improve environmental quality. Tofu industry waste management and treatment can be done by identifying the generation of waste that is a priority to be treated and choosing waste treatment technology. There are three alternatives for wastewater treatment from the tofu industry: the chlorine in wastewater, ponds by forming biofilms using biofilter media, and Trickling Filters.

Abstract This study aims to determine the effect of biochar dose from urban waste and the concentration of eco-enzymes and their interactions on the growth and yield of shallots. The research was carried out in the greenhouse of the Faculty of Agriculture,Warmadewa University with an altitude of 25 m above sea level, and took place from April to June 2021. This study used a factorial randomized block design method consisting of two factors. The first factor is the dose of biochar with 4 levels (0; 5; 10; and 15 tons ha-1), while the second factor is the concentration of eco-enzyme which consists of 4 treatment levels (0; 7.5; 15.0; and 22.5 ml l-1). The results showed that the interaction between the dose of biochar and the concentration of eco-enzyme had a significant effect on the fresh weight of the stover per clump and had a very significant effect on the dry weight of the stover per clump, but had no significant effect on other variables. The treatment dose of biochar and eco-enzyme had a very significant effect on all observed variables. The results showed that the biochar and eco-enzyme treatments had a very significant effect on all observed variables. The application of biochar and eco-enzyme has a very significant effect on all observed variables. The provision of biochar treatment from urban waste was able to increase the fresh weight of tubers in the 15-ton ha-1 treatment, which was an increase of 39.40% compared to without biochar, while the highest fresh fruit weight was obtained in the eco-enzyme treatment of 22.5 ml l-1, which increased by 29.77% compared without eco-enzyme. Keywords: Biochar; urban waste; eco-enzyme; shallots

This study aims to determine the effect of Gypsum and Etepon on the yield of Siamese orange (Citrus nobilis Var Microcarpa. L) conducted in Belancan Village, Kintamani District, Bangli Regency from December 2020 to July 2021. This study used a randomized block design (RAK) with 2 factors arranged in a factorial manner. The first factor that was tried was the dose of gypsum fertilizer (G) which consisted of 4 levels, namely: G0 (0 g/tree), G1 (250 g/tree), G2 (500 g/tree) and G3 (750 g/tree. While the second factor is the concentration of etepon (E) which consists of 3 levels, namely: E0 (0 ml/l water/tree), E1 (0.75 ml//l water/tree) and E2 (1.5 ml/l water)/tree). Thus, there were 12 combination treatments, each of which was repeated 3 times so that 36 citrus trees were needed. The results showed that the interaction between the dose of gypsum and the concentration of etepon had no significant effect on all observed variables. The highest harvested fruit weight per tree was obtained at a dose of gypsum 750 g/tree which was 6.32 kg or an increase of 70.35% when compared to treatment without gypsum which was only 3.71 kg. The highest harvested fruit weight per tree was obtained in the etepon treatment with a concentration of 1.5 ml/l/tree, which was 6.54 kg, an increase of 51.38% compared to the treatment without etepon, which was only 4.32 kg. Keywords: dose, etepon, gypsum, Siamese orange, yield

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.
