Abstract

Ganoderma is one of the fungi that can function as a medicine, besides it can function as a decomposer to accelerate the material cycle in the forest ecosystem. This study aims to determine the spread of types of Ganoderma especially along the Sebau road in the Gunung Rinjani National Park area. This study used a descriptive explorative line transect and was carried out in May 2015. The identification of Ganoderma samples was carried out by matching the macroscopic Ganoderma profile with an identification book and available literature. Makrofungi found 14 species, 5 of which included the Ganodermataceae family, namely Ganoderma sp., Ganoderma adspersum, Ganoderma applanatum, Ganoderma lucidium, and Ganoderma tsugae while 9 species including the Polyporaceae family included Polyporus sp., Polyporus versicolor, Trametes elegan, Trametes versicolor, Trametes sp., Trametes sp.2, Datronia sp., Pycnoporus cinnabarinus, and Microporus sp.

Abstract

Gastropoda included in the Mollusca phylum. Gastropoda are commonly found in watersheds. Jangkok River is a watershed that flows from the mountains of West Lombok Regency across Mataram City and interacts the most with human activities. This study aims to: 1) identify the type of Gastropoda found in the Jangkok River, Mataram City; and 2) developing research results on the diversity of Gastropod species in the Jangkok River in Mataram City as the basis for the Formulation of Ecology Practicum Guidelines. This type of research is exploratory descriptive research and development research. Descriptive research analyzes only to the level of description that is to analyze and present data systemically, so that it can be more easily understood and concluded, and exploratory research is a type of research that aims to find something new in the form of a grouping of symptoms, facts and certain diseases. While development research is an attempt to develop an effective product for use by schools and colleges, and not to test theory. Data collection techniques used for descriptive exploratory research are observation and documentation, while for development research are validation, legibility testing, and documentation. The data analysis technique was using species diversity index and percentage technique. The results showed that there were 51 Gastropod individuals consisting of 7 species that have been found including Potamopyrgus antipodarum, Mya arenaria, Ilyanasa aobsoleta, Pomacea canaliculata, Pomace ainsaluran, Poamarcobula amurensis, and Melanoides punctata. Species diversity at the upstream station has a very low diversity index with a value of 0, the middle station has a diversity index with a value of 0,91 indicating low diversity, and downstream stations have a diversity index with a value of 1,29 indicating moderate diversity. The average value of the validation test for practicum is 80,6%, and the readability test for students is 81%, with these results the practicum instructions that have been prepared are in the very valid category and do not need to be revised.

Abstract

Flower H. sabdariffa is efficacious as an antiseptic, demulcent (neutralizes stomach acid), digestif (diuretic digestion, onthemintic (anti-worms), refrigerant (cooling effect), and treat cancer, cough, stomach ulcers, bloating abdomen, and prevent liver disease However, clinical trials utilizing H. sabdariffa to prevent and treat S. typhimurium infection infections have not been done. Therefore, this study was conducted to determine the effect of H. sabdariffa inhibit the growth and kill the bacteria causing S. typhimurium infection disease on The extraction of H. sabdariffa was performed by infusa method using aquadest solvent in vitro test by using the well method by measuring the diameter of clear zone formed around the well. After that, it was continued by in vivo test by giving oral extract of H. sabdariffa to the mice which has been infected S. typhimurium. From this study dipe it is found that the extract of H. sabdariffa has an antibacterial effect with the inhibitory zone obtained.

Abstract

Ancar River is a river that is used by many residents for various activities, such as agricultural activities, fisheries, and planting water spinach. In addition to these activities, the Ancar River is also used as a place for domestic waste disposal and disposal of the tofu waste industry so that it can have a negative impact on water resources, including causing a decrease in water quality. The Annelida response to environmental changes can be used to see the effect of various activities, such as the impact of industrial activities, agriculture, and land use. This study aims to assess the community structure of Annelida as bioindicators of the waters against the content of polluted material found in the Ancar River. This research is descriptive explorative, using quantitative and qualitative approaches. This study uses the "Sampling Purposive" method, which is the determination of the observation station based on the use of land around the Ancar River environment. Each sampling station is carried out in 3 points, namely left, center and right of the river. Annelida obtained in the Ancar River consist of two classes namely Oligochaeta and Hirudinea. Oligochaeta class consists of Tubifex sp., Lumbricus terrestris, Hirudinea class consisting of Hirudo medicinalis. The community structure of Annelida can be used as a indicator of river pollution. From the results of the study it was found that the Ancar River had experienced pollution caused by organic matter both from household waste and tofu industrial waste. Based on the BOD value it is known that station 1 is categorized as uncontaminated location, stations 2 and 4 are lightly polluted, and stations 3, 5 and 6 are moderately polluted.
