This study aims to analyze the inhibition of the development of the F1 generation of rice beetles by nutmeg and clove flower essential oils, and to determine the mortality of rice beetles against nutmeg and clove flower essential oils. The stages of the research started from rearing the rice beetle, preparing test insects, making variations in doses, treatments, and analysis. Two tests were conducted in the study, the first for inhibition of F1 generation activity and the percentage of mortality using the contact method (filter paper). The results showed that nutmeg and clove oil had an effect on the inhibition of the rice beetle F1 generation. Nutmeg oil has the best inhibition power with the percentage of F1 generation inhibition up to 100%. The mortality test using the filter paper method showed that for 48 hours nutmeg essential oil was able to kill rice beetles at all concentrations, namely 5-20% to 100%, while the percentage of 100% mortality was only found in the treatment with clove oil at the highest concentration (20%). The results showed that nutmeg oil showed better results than clove oil for controlling S. oryzae warehouse pests.

Abstract Microbial detection takes a long time to produce positive results, so a quicker detection method was chosen. Multiplex polymerase chain reaction (m-PCR) identified bacterial strains in less than 24 hours, detects E.coli specifically, and is faster than traditional methods. The goal of this study was to use m-PCR to detect early pathogenic E.coli bacteria in several drinking water sources in the Abepura district of Papua Indonesia as a parameter of pollution and water quality. The Chelex100 and microwave combination method was used to extract DNA. The first round of testing was done at four different concentrations: 0.125, 0.250, 0.375, and 0.500 M. The purity of the extracted DNA was good, ranging from 1.80 to 1.94. The optimum primer concentration for multiplexing applications is 0.25 uM for lt primer; 0.125 uM for stx2 and eae primer, with an annealing temperature of 55oC. m-PCR has been shown to quickly detect pathogenic E. coli in water samples. In the PCR process, E.coli DNA template was obtained with high purity (1.80-1.94) and concentration (576.9-4301.6 ng/uL) . Each multiplex set included three primer pairs for the target gene lt-eae-stx2 on ETEC-EPEC and EHEC respectively. The m-PCR process showed excellent results, and this findings can be considered as a reference for water analysis in several drinking sources in Papua Province.

Learning motivation is an action that drives a person to do a learning activity and achieve the purpose of learning. Without the motivation to learn, learning becomes meaningless. The problem found was there is a lack of student motivation to learn Physics. A solution that can be used to grow a student's learning motivation is the application of a design model. The method used was a qualitative descriptive method at one of the high schools in East Lampung. The purpose of this writing is to describe the role of a physics teacher in motivating students to learn physics by using the Backward by Design model. The result of the research shows that the Backward by Design model can be used by the teacher to motivate students in learning Physics.

Based on the results of this case study, it was found that the severity of the disease using ImageJ software was on citrus leaves at the first location (10.641%), citrus leaves at the second location (53.278%), and citrus leaves at the third location (15.828%) which were generally the fruit plants caused by fungi and based on the results of Plantix software data, diseases in the first, second, and third locations of citrus leaves were caused by bacterial diseases. Based on the results of bacterial cell culture, isolates were found to be round white in color with a slight yellowness which is a characteristic of Xanthomonas axonopodis bacteria with a large number of ±12 colonies and a smaller number of ±35 colonies. Using software and imageJ can help farmers to find out the types of pests that attack citrus plants so that farmers can handle plants to minimize damage to citrus plants caused by pests.
