The existence of a type of parasitoid in an area with a certain height is largely determined by several factors, including the physical environment, space, feed sources, the presence of other parasites and human intervention. The purpose of this study was to determine the community structure of parasitoid associated with stone leek leafminer including abundance index, diversity index and dominance index in several locations of onion planting in Bali. Field surveys are conducted regularly during one planting season. On the location of onion plantations with an altitude of<500 m asl, covering the Badung Regency and Gianyar Regencies, on the onion planting area at that location no parasitoid was found (abundance index R1 = 0.00; diversity index H’= 0.00; dominance index D = 0.00). In locations with a height of ≥500-1000 m asl, covering several locations in Tabanan Regency, there were 2 types of parasitoid, Hemiptarsenus varicornis as many 3 adult (abundance index R1 = 0.6213; diversity index H’ = 0.2544; dominance index D = 0.0100) and Opius sp. 22 adult (abundance index R1 = 6.5239; diversity index H’= 0.1125; dominance index D = 0.7700). In locations with an altitude of ≥1000 m asl, covering several locations in Tabanan Regency and Bangli Regency, there were also 2 types of parasitoid namely H. varicornis 5 adult (abundance index R1 = 1.2941; diversity index H’ = 0.3380; dominance index D = 0.0433) and Opius sp. 17 adult (abundance index R1 = 5.1763; diversity index H’= 0.2013; dominance index D = 0.5887).

One area that has oil palm plantations is Makmur Jaya Village, Tikke Raya District, Pasangkayu Regency (formerly called North Mamuju Regency), West Sulawesi Province. One of the problems in the cultivation of oil palm is weeds. This study aims to determine the types of puzzle weeds in the oil palm plantation in Makmur Jaya Village, Tikke Raya District, Pasangkayu Regency, West Sulawesi Province. Based on the research, there were 3 types of puzzle weeds in the Makmur Jaya Village oil palm plantation, namely Cyperus compressus, C.rotundus, and Fimbristylis milliacea. Riddle weeds have leaves similar to narrow-leaf weeds, but have a mendong stem (consisting of only one long segment) and are also triangular in shape. Riddle weeds have allelopathic compounds which make it difficult for palm oil plants to grow.

This study aims to determine the relationship of social domographic factors with the behavior of farmers in applying pesticides to shallots in Sigi Biromaru District, Sigi Regency. This research uses quantitative methods using univariate analysis for frequency distribution and bivariate analysis (chi square) to determine the correlation between variables. Both use Statistical Product and Service Solutions (SPSS) 20.0. Determination of the location of the study was conducted purposively based on previous observations. The area is a center of shallot and horticulture plants in Sigi Regency, namely; Oloboju Village and Bulupountu Village, Sigi Biromaru District. The results of the study concluded that the use of pesticides by shallot farmers was over intensity with the reason for maximum production results. Unwise behavior of farmers in controlling pests and diseases with the high use of pesticides in the field, shows that there is no relationship between age, education, experience and Integrated Pest controlling (IPC) training with the behavior of shallot farmers in applying pesticides.

The purposes of this research the examine the effectiveness various concentrations neem leaf ekstract on the intensity of attack Liriomyza spp on shallot Lembah Palu variety . Field research was carried out in Guntarano Village, Tanantovea Subdistrict, Donggala Regency, Central Sulawesi. This research conducted from February to April 2016 .The experiment was done using Randomized Complete Block Design with three replications, consists of six treatments, i.e. P0 : control (without aplication neem leaf ekstract); P1: neem leaf ekstract 10 gr /litre; P2 : neem leaf ekstract 20 gr / litre; P3 : neem leaf ekstract 30 gr / litre; P4 : neem leaf ekstract 40 gr / litre; P5 : neem leaf ekstract 50 gr / litre. To find out the effect of threatment, the analysis of variance, and the real influence is continued with the standard ά = 0.05 BNT test. The results showed that use of seed and leaf extracts of neem plant can control Liriomyza spp attack, only 3,04 percent of attack rate and shallot Lembah Palu variety productivity is 3,02/area.

The aims of this experiments was to evaluate the appropriate concentration of BAP for shoots induction of orange via in vitro culture. This experiment was conducted in Plant Biotechnology Laboratory, Faculty of Agriculture, Tadulako University from Mei to August 2017. This experiment used a Completely Randomized Design with five treatments, namely 0.5 ppm BAP, 1.0 ppm BAP, 1.5 ppm BAP, 2.0 ppm and 2.5 ppm.. Data was analyzed using analysis of variance and differences between means of the treatments were determined by Honestly Significant Difference test at 5% level. Results of this experiment indicated that the most suitable concentration of BAP for the shoots induction of orange was the medium culture supplemented with 0.5 ppm BAP. In such medium composition, the quickest and the highest number of shoot formation was obtained as well as the highest number of leaf formation at 6 weeks after culture, namely 3.02 days after culture, 1.52 shoots and 2.40 leaves per explant, respectively.

This study aims to determine the level of Feasibility of "Cahaya Ummul " Milling. Determination of the object and location of the study was intentionally determined. The results showed that the analysis of the payback period or the length of time the investment will be returned occurred in 9 years 3 months, NPV analysis or estimated future cash flows discounted at 14% with a total NPV of 232,480,306 > 0 (positive), Net B / C analysis is the value of the ratio between the number of positive net benefit PVs with the number of negative net benefit PVs obtained a value of 1.19> 1, and the IRR analysis of the efficient level of an investment of 21,016% with an interest rate of 14% when evaluating. So this business was declared worth the effort.
