Abstract

Daun Pare (Momordica charantia) mengandung senyawa flavonoid, saponin, tannin, triterpenoid, dan alkaloid dengan berbagai mekanisme antibakteri. Penelitian ini bertujuan menguji ekstrak etanol daun pare (Momordica charantia) dalam menghambat pertumbuhan bakteri Staphylococcus aureus dan seberapa besar ekstrak etanol daun pare (M. charantia) dalam menghambat pertumbuhan bakteri Staphylococcus aureus. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan metode Cakram. Hasil penelitian menunjukkan bahwa ekstrak daun pare (M. charantia) dapat menghambat pertumbuhan bakteri Staphylococcus aureus dengan luas zona hambat yang terbentuk pada hari pertama, konsentrasi 10% yaitu 0,2 cm2, 15% yaitu 0,3 cm2, 20% yaitu 0,4 cm2, 25% yaitu 0,5 cm2 dan 0% (kontrol negatif). Ekstrak daun pare mempunyai kemampuan menghambat pertumbuahan bakteri Staphyloccocus aureus. Kata Kunci: Daya Hambat, Esktrak Etanol, Antibakteri, Momordica charantia, Staphylococcus aureus

Abstract

The Crested black macaque (Macaca nigra) is an endemic species to the Sulawesi Island, limited distribution, and Critically Endangered on the IUCN red list. The population density in the Tangkoko Conservation Forest Management Unit (CFMU) has decreased significantly due to habitat destruction and hunting. Existing data are based on the study in the northern part of Tangkoko. Currently, data from the southern is urgently needed so that population data covers the entire area, including to identify the habitat quality. The aims of this study was to (1) analyze the population density level of Crested black macaque at the Tangkoko CFMU, (2) identify the habitat characterize of Crested black macaque at the Tangkoko CFMU, (3) analyze the correlation between Crested black macaque density and habitat quality at the Tangkoko CFMU. The study was conducted from January to March 2020 in the sothern of Tangkoko CFMU, North Sulawesi. The data collection on the density of Crested black macaque is done by animals directly inventorying through surveys in the field. Observations are carried out by walking at speeds of 1 - 1.5 km / h on each track and stopping at every 100 m to observe the surroundings. Data recorded is the number of individuals found using the line transect method. Vegetation data collection method used is habitat quality data collection carried out by making sample plots measuring 25 m x 25 m for tree level observations in lines with each distance between plots is 250 m. Data recorded for dominance of vegetation are species names, number of individuals, and diameter at breast height of trees. The results showed that (1) the population density level of Crested black macaque was 15 individuals/km2. The highest amount of density is found on the D4 was 72 individu/km2, the lowest on D1, D5, D6, and D7 with no macaques; (2) vegetation analyzed at 45 plots were important value index with the highest value of 86,95 is Ficus variegata on line D7 for tree level, and Theobroma cacao for pole level with highest value of 120,80 on line D4; (3) the correlation between density of Crested black macaque and habitat quality that shows a positive value based on the Pearson correlation test. Further research is needed to determine the relationship between population density, habitat disturbance, and hunting pressure.

Abstract

In Manado City flood problem is one of the main problem, one of the flood point is in Kelurahan Perkamil. The objective of implementing the appropriate technology for the biopori flood mitigation is one of the solutions empowering the community to (1) reduce the potential for flooding in Manado city, especially Perkamil village. (2) preventing worsening of environmental damage due to water-surface runoff of the ground. The specific targets to be achieved (1) reduce the flow of land surface water from residential or residential areas; (2) Improve soil texture with organic waste material so that the rate of water catchment into the soil increases, this has an impact on the mitigation of water flow runoff and underground water conservation. The implementation method is to conduct training on all head of the environment and some people in the village make Biopori hole, to manage flooding and household waste with biopori technique. the depth of the biopori hole is 100 cm and a diameter of 10 cm. Materials and tools, dirt drill, paralon, and organic waste. The training results of all trainees can make biopori holes, understand their functions and benefits in mitigating flood potential, manage household organic waste and yard. Participants know that the soil can be used as a soil bio composter to produce organic compost that raw materials for household organic waste and yard.
