Golden cyst nematode is one of the important pests that causes potatoes loss yield. Globodera rostochiensis is the pest that difficult to control because it can withstand in adverse environmental conditions. In Indonesia, golden cyst nematode was first discovered in 2003 in East Java. One of the methods that used in this research is intercropping system. The main objectives in this study was to examine how the effect of turmeric plants on intercropping system to cysts population and amount of eggs on golden cyst nematode and the use of turmeric plants is expected to reduce the application of nematicides. This research was conducted on November 2017-February 2018, in Dieng Banjarnegara. The results show the effect of turmeric on intercropping system had not been able to control the cysts population through the eggs, beside that the eggs are not decrease due to genetic factors of each nematode and environment that effect on eggs formation. But the balancing of use turmeric plants on intercropping system could reduce the cysts population. It can be seen on K1P1 (1 Potato : 1 Turmeric) treatment that showed of decreases of cysts population compared to control treatment. The difference on cysts population is caused by turmeric root exudates.

The increasing demand of jamu/traditional medicine was followed by the demands of raw materials quality based on Good Agricultural and Collection Practices (GACP) yield and standard quality. Bio-insecticide is an effort to fulfill the standard based on GACP. Indonesian’s biodiversity have many potential raw materials of bio-insecticides, such as Tithonia diversifolia. The most common pest in the medicinal plants is Aleurodicus dugesii (giant whiteflies), this insect belong to Hemiptera ordo and Aleyrodidae family. The research was conducted to determine the antifeedant and anti-oviposition activity of Tithonia bio-insecticide against giant whitefly on Coleus species. The experimental design was completely randomized design (CRD) with five treatments of Tithonia leaves extract consentrations. Those consentrations were 0, 4, 2, 1, and 0,5 mg L-1. The treatments were tested by using a no-choice test with three replications. The extract of Tithonia leaves was prepared by infundation method by using water solvent. Results showed that extracts of Tithonia with the smallest concentration (0,5 mg L-1) has an active role as an anti-oviposition and antifeedant on giant whiteflies.

Tomato (Lycopersicum esculentum Mill) is one of horticulture commodities with high economic value and still need seriously handling especially for increasing fruits quality and quantity. However the production of tomato has not fullfilleed the demand yet. Therefore it is necessary to develop production. On lowland, the issue not only high temperature but also availability of water is unpredictable.This study aimed to investigate the effect of irrigation frequency on the growth of Mutiara, Opal, and Gondol tomato variety. This research was conducted at the Greenhouse Laboratory of the Agriculture Faculty, Sebelas Maret University with attitude 95 m asl. Implementation of the research conducted from January to May 2013. This research used completely randomized factorial design with two factors, namely variety of tomato (Gondol, Opal and Mutiara) and watering frequencies (everyday, once in 3 days, once in 6 days, and once in 9 days). The results showed that plant height, number of leaves and number of branches are influenced by the variety of tomato and irrigation frequency, whereas chorophyl content is influenced by the watering frequency. Growth component and chlorophyll content of tomato decreased with increasing irrigation frequency.

Durian is a tropical native fruit from Indonesia with a distinctive flavor. Durian can be propagated durian generatively and vegetatively. Generative propagation of durian can be done by germinating seeds, which is vegetative propagation can be done by top grafting. Top grafting can be accelerated by the addition of plant growth regulators. Growth regulating substances in coconut water complex compounds are useful in differentiating cells. This study aimed to determine the effect of various concentrations of coconut water and the best type of grafting for the success of durian tops grafting. In this study was conducted in horticultural breeding centers Ranukitri Mojogedang Karanganyar April to September 2012. This research used Completely Randomized Design (CRD), which consisted of 2 types of treatment that top grafting, namely: cleft grafting, slash grafting, side grafting and coconut water concentration with 5 levels: 0%, 25%, 50%, 75%, 100% with 5 replications, so that the total treatment was 75. The results showed that the type of cleft grafting was the best grafting type to be used for the success of top grafting compared with other grafting types. Treating coconut water with a concentration of 25% was able to optimize the growth of durian top grafting than other concentrations.

Botanical pesticides produced from tobacco plants are reported to be the most toxic compared to other types of plants because it contain 2-8% nicotine substances. The objective of this research was to examine the effect of tobacco dust waste extracts and determine the concentration of the most effective tobacco dust waste extract against armyworms. This research was conducted in Laboratory of Pest and Plant Disease and C Green House Faculty of Agriculture Universitas Sebelas Maret Surakarta from April-July 2018. The stages of this study include the multiplication of S. litura test larvae, preparation of botanical insecticides from tobacco dust waste, mortality test, antifeedant test and phytotoxicity test. This study used a completely randomized design with 6 treatments and 4 replications. The results showed that tobacco dust waste was able to increase the mortality of S. litura larvae, but with a slower effect compared to the treatment of profenofos. Feeding barriers are not seen in the test larvae. The phytotoxicity test shows that tobacco dust waste was not toxic to plants. Based on probit analysis, the concentration of tobacco dust waste which was capable of killing 50% of the population of S. litura was equal to 53.10 gL-1.
