Abstract

Abstract: Aedes aegypti L. is a mosquito carrying dengue virus that causes dengue fever, especially in Southeast Asia which is a tropical rain forest region which is a habitat for mosquito growth. Aedes aegypti L. mosquito control is carried out by chemical means of fogging and using abate but this control actually causes Aedes aegypti L. mosquitoes to become resistant or immune to chemical drugs so that a new breakthrough is created by making bioinsecticides biologically to eradicate the Aedes aegypti L. mosquito. with characteristics that are environmentally friendly and do not kill non-target animals and cause the Aedes aegypti L. mosquito not to become resistant. To be able to realize this desire so that the sugar cane granules extract of Annona squamosa L. containing active compounds in the form of annonain and squamosin so that they are toxic to Aedes aegypti L. mosquito larvae. Further research is to test the heating temperature level of the granules of Annona squamosa L. extract temperature of 40 ° C and 60 ° C which is more deadly of Aedes aegypti L. mosquito larvae. This research method uses a completely randomized design with four repetitions. The temperature of 60 ° C uses concentrations of 1 ppm, 6 ppm, 12 ppm, 18 ppm, 24 ppm and 30 ppm. As for the temperature of 40 ° C using concentrations of 1 ppm, 7 ppm, 14 ppm, 21 ppm, 28 ppm, and 35 ppm, each temperature compared with aquadest and abate. Data analyzed using probit analysis to determine the LC50, then followed by a statistical test paired sample T-test with SPSS to find out a significant difference between heating temperatures of 40 ° C to 60 ° C. These results then show that a higher temperature of 60 ° C has a higher level of toxicity compared to a lower temperature of 40 ° C.

Abstract

Sponge plastic is one of the plastic wastes that is difficult to degrade. Recently research reported that Tenebrio molitor L larvae have the potential capability to degrade plastic waste. But still a lack information according to the effect of feed composition on survival, and growth of T. molitor L larvae. The purpose of this study was to determine the effect of plastic feed composition on the rate of degradation of sponge plastic waste, survival, and growth of T. molitor L larvae. The method used in this study was an experimental laboratory using Completely Randomized Design (CRD) and using controls and six treatments with 3 repetition times. The parameters measured in this study were survival (%), body length growth (cm/week) and body biomass (gram/week), and degradation rate (gram/week). The data obtained from the research results will be analyzed using ANOVA which is then tested by Duncan. The results showed that feed composition had a significant effect (p=0.001) on the rate of degradation of plastic sponge waste, survival (p=0.000), and growth (p=0.001) of T. molitor L larvae. degradation, survival, and growth of T. molitor L. larvae.

Abstract

This study aims to examine the validity of the MORISE learning model. The research design used follows the Education Research and Development method, which involves the development of the model starting from designing the model to implementing it. The validity test of the MORISE model is conducted by two science education faculty members from the Postgraduate Program at UNEJ as expert validators, and one user validator, with the purpose of obtaining feedback and improvements for the learning model developed by the researcher. The first expert validator gave a score of 93%, the second expert validator gave a score of 84%, and the user validator gave a score of 95%. The average result of the final validation is 91%, falling within the highly valid criteria (>81.25%), thus indicating that the MORISE learning model can be used without revisions.
