Abstract

The downstream of DEA surfactant products has great potential in the industrial world, one of which is agricultural product in the form of insecticides. The purpose of this study is to examine the scale multiplication of insecticide products for the brown planthopper on a pilot scale of 25 l and an industrial scale of 1000 l and calculating the selling price of insecticide products with different profit variations based on the cost of production. The scale multiplication was based on the unit of power per unit volume (Pg /V) which had a fixed value. The optimal agitation speed in product formation was obtained from a small-scale experiment, and the results were used to obtain the agitation speed on a large scale, which required the same power per unit volume. A simple step to calculate multiplication of the scale was by using the basic geometric shape of the tools used in the process performed. The determination of the tools used was based on the effectiveness of the two types of tools, namely mixer and homogenizer. Furthermore, the multiplication of the scale into geometric shapes on the scale of 25 l was carried out and continued on the scale of 1000 l. The required parameters in determining the geometry of the reactor were impeller diameter (Di), tank diameter (Dt), sample of liquid height (HL), impeller rotation (Ni). The results obtained showed that the effectiveness of insecticide production was higher in the use of this type of homogenizer tool. In this study, the power per unit volume (Pg /V) was fixed. Calculation data obtained from the laboratory scale include Ht; HL; Di and Dt. On the scale of 25 L were 28.2; 19.5; 12.2 and 33.6 cm, meanwhile on the scale of 1000 L were 95.7; 66.9; 41.7 and 115.4 cm. The result of the calculation of the impeller rotation speed at a scale multiplication of 1000 L was 396 rpm. The calculation of the selling price of the brown planthopper insecticide per bottle (200 ml) for the 50% profit margin was IDR 13,043, the 100% profit margin was IDR 17,390 and the 200% profit margin was IDR 26,086.

Abstract

Integrity of attitude, behavior, openness and honesty are important things that capture fisheries business actors must have. Deviations in integrity are allegedly equivalent to criminal acts of corruption because they have the potential to cause very large losses to the state, which are difficult to detect and the value of the losses. In addition, failure to fulfill integrity has a huge potential for loss of sustainability of fisheries resources in the long term, and is difficult to recover. The research aims to examine the relationship between the integrity of capture fisheries business actors and efforts to preserve fish and marine resources. Descriptive research using a literature study approach combined with a limited discussion process with aquatic resource management experts in order tomaintain the sustainability of fish population dynamics due to capture fisheries exploration. The research results show that the integrity component which concerns attitudes, behavior, openness and honesty of capture fisheries business actors is an absolute thing that must be implemented and developed. Potential state losses worth billions of rupiah accompanied by massive damage to marine resources can be avoided if capture fisheries business actors carry out exploration properly and report their activities honestly and openly to the competent government authorities as a control over resource sustainability.
