Abstract

The addition of cow rumen fluid to waste containing cellulose can help decompose the cellulose contained in it through the composting process. Organic waste and paper waste containing ink are wastes that contain cellulose. However, the waste paper containing ink contains Lead (Pb) which is used as a color binding agent in the ink. In the composting process, in addition to the degradation process of organic components in paper, it is necessary to know the process of decreasing the Pb content in the compost material. This study was conducted with the aim of comparing the Pb content after application of cow rumen fluid on a mixture of used paper containing ink and organic waste for 60 days with used paper with ink for 7 days. The objects in this study consisted of two groups, the first group was used paper containing ink mixed with organic waste in a ratio of 1:1, then cow rumen fluid was added and incubated for 60 days, while the second group was inked waste paper added with cow rumen fluid and incubated for 7 days. Pb test incubation using AAS (Atomic Adsorption Spectrophotometer) method. The data were statistically tested by Independent T Test on SPSS 23 Software. The conclusions obtained from this study were the incubation time of inked paper waste with the addition of rumen fluid showed that the difference in Pb levels was not significant. The Pb content in both experimental groups was in accordance with the provisions of SNI 19-7030-2004.

Abstract

Malang Regency is an endemic area for cases of DHF (Dengue Hemorrhagic Fever) in East Java Province. One of the efforts to reduce the number of cases is to control the breeding of the Aedes aegypti mosquito which is the main vector. However, this will depend on the susceptibility status of Aedes aegypti to the insecticides used, one of which is malathion. This study aims to determine the susceptibility status of Aedes aegypti mosquitoes to malathion insecticides in Malang Regency in the southern part. This descriptive observational study used adult Aedes aegypti mosquitoes obtained from the landing collection of larvae from three sub-districts in Malang Regency in the southern part (Kepanjen, Gondanglegi, and Bantur). The location selection was done by simple random sampling technique. The larvae of the Aedes aegypti mosquito were then reared in the Chemistry Laboratory, University of Muhammadiyah Malang. Adult mosquitoes with stomach conditions full of sugar were then tested using the susceptibility test which refers to WHO standards. The results showed that the mortality rate of the tested mosquitoes in the Districts of Kepanjen, Gondanglegi, and Bantur, respectively, reached 98%, 93%, and 96%. This shows that the Aedes aegypti mosquitoes in the three locations are classified as tolerant to the insecticide malathion by 0.8%. Thus, it can be concluded that the insecticide malathion is still effectively used as vector control for DHF (Dengue Hemorrhagic Fever) in Malang Regency.

Abstract

Carotenoid pigments are commonly found in fruits and vegetables, but carotenoids can also be produced by microorganisms such as yeasts. Carotenoids have several benefits, including antioxidant compounds and vitamin A precursors. Production of carotenoids by microorganisms depends on various factors, such as pH, temperature, and nutrient content in the media. This study aimed to determine the optimum concentration of molasses supplementation and the initial pH of the media for carotenoid production by the red yeast Rhodosporidium paludigenum. In this study, the red yeast was cultivated in Yeast Peptone Dextrose (YPD) media supplemented with molasses, with a total sugar concentration of 2% in the media. This study had a factorial design with eight treatment groups, i.e., molasses supplementation of 0%, 25%, 50%, and 75% in the media with initial pH of 5 and 6 for each molasses supplementation. The results showed that the culture in the media with supplementation of 25% molasses and pH 5 produced the highest levels of carotenoids when compared to those with 50% and 75% molasses supplementation concentrations. The yields of β-carotene and xanthophyll over biomass dry-weight in the media with 25% molasses supplementation at pH 5 were 26.67 μg/g and 31.15 μg/g, respectively. Nevertheless, the red yeast in the media without supplementation (0%) produced the highest carotenoid concentration among all treatments.

Abstract

The practicum method is one of the strategies in learning that includes the cognitive, affective and psychomotor domains as well as a learning activity that aims to give students the opportunity to test and apply theory with facilities using laboratories or outside the laboratory. In practicum, teachers usually use LKPD as a guide for practicum activities. However, based on the results of previous analysis and research, actually only a small portion of the LKPD can be used. The purpose of this research is to analyze and reconstruct the design of food testing laboratory activities. The type of research used is descriptive qualitative and the sampling is done by purposive sampling with a total of 5 DKL. The analysis conducted on DKL is measured in terms of competence, practice, and knowledge construction. The results obtained that the components of competence and knowledge construction are still low, while the practical components are sufficient. This shows that there are still many food tests that cannot support competence and knowledge construction.
