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

Cocoa parasite leaves (Dendrophthoe pentandra (L.) Miq) belong to parasitic plants against hosts which are potentially used as traditional medicinal ingredients. However, the efficacy of cocoa parasite leaves is still not widely known by the public. One of the properties from cacao parasitic leaves is able to treat mild diseases such as smallpox, hookworm, flu, cough and diarrhea as well as being able to be used as a treatment for serious diseases such as tumors and cancer. The bacteria causing infection generally come from gram negative bacteria, namely Shigella dysenteriae and Salmonella typhi which refer to enteropathogenic bacteria causing infection to the host. The existing controls still use antibiotic drugs that are used less procedurally and causing bacteria more resistant. Cocoa parasite leaf extract contains active compounds in the form of alkaloids and saponins which play a role in inhibiting bacterial growth. This study aims to determine the effective concentration on the effect of cocoa parasite leaf extract to the growth of Shigella dysenteriae and Salmonella typhi bacteria. The research method was by using diffusion so that by using wells with 5 repetitions. The concentration used was 8%, 10%, 12%, 14%, 16%. Data were analyzed by using ANOVA analysis to determine the effective concentration on the effect of extracts to the inhibition of bacterial growth. The significant values were indicated at 0,000 against Shigella dysenteriae and 0.042 bacteria against Salmonella typhi (<0,05). The data revealed that cocoa parasite leaf extract has the potential to inhibit the growth of Shigella dysenteriae and Salmonella typhi bacteria.

Abstract

The quality of food that is good in bacteriological, chemical and physical must always be maintained in order to avoid diseases or health problems. Healthy and safe food is an important factor to improve the standard of public health. Seblak is a ready-to-eat Indonesian food which until now has never been carried out research about what kinds of bacteria in it. Seblak is a food made from raw crackers which is then deliberately soaked using hot water to have a chewy texture. This study aims to determine what types of bacteria are contained in seblak, through the process of isolation and identification in the macroscopic, microscopic and biochemical way. This study used 5 samples, which was repeated 5 times for each sample. Bacteria were isolated from the sample using spread plate techniques and observed by growing colonies on the plate. Each different colonies was observed microscopically through gram staining and endospore staining. To strengthen the data, biochemical tests were also carried out, biochemical tests that have been done in this study were the oxidase test, catalase test, and indole test. The results of the study showed that the bacteria that were found from the samples are in the genus of Bacillus sp. because they show the morphological characteristics of the colonies that form concentric circles, meanwhile, microscopic observations show morphological characteristics of cells in the form of gram-negative bacilli and have the endospores.

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.
