Abstract

Gunung Gede Pangrango National Park (GGPNP) is a representative type of mountainous tropical rain forest ecosystem that is rich in biodiversity potential. Research on the diversity of Macrofungi has not been widely, especially in the Cibeureum Waterfall Trail, GGPNP. This study aims to study the diversity of Macrofungi in the Cibeureum Waterfall Trail, GGPNP route. The research was carried out from November 2020 to August 2021. Sampling was carried out by the roaming method. The results of the study of Macrofungi in the Cibeureum Waterfall Trail, GGPNP route obtained 2 phyllum, 9 orders, 22 families and 57 species with a total of 1,360 individuals. The value of the Shannon-Wiener diversity index (H') belongs to the medium category, the evenness index (E) is moderate and the dominance index (D) is low. The abiotic conditions in this area based on the recording of temperature, pH, humidity and light intensity indicate conditions that support the life of Macrofungi in the Cibeureum Waterfall Trail, GGPNP route.

Abstract

PT. Aneka Tambang has reclaimed land due to gold production activities.  Reclamation land is a process whereby the damaged land is repaired to its natural state.  Indicators of succession can be showed in the presence of plants and animals.  Birds are a good indicator for assessing biodiversity in a region, because can occupy a large habitat of  near the top of the food chain.  The spread of plant seeds can be done by birds and mammals through its feces. Identification and observation of bird and mammal diversity can be used to improve the conservation of birds and mammals in the area.  The purpose of this research was  to study the diversity of birds and mammals.  The method used were Indices Ponctuels d’Abondance(IPA) method for birdwatching and transect lines for mammalian observation.  Result showed  33 speciesof birds and 9 species of mammals were found in this study. The bird species was dominated by the Cucak Kutilang type and the mammal was dominated by Squirrel Kekes.Key words : PT. Aneka Tambang, diversity ,bird ,mammal

Abstract

Salmonella enteritidis contamination in chicken meat causes chicken meat to rapidly decay. The use of chemical preservatives is very harmful, therefore the use of natural materials is recommended because it is safer to consume for humans. One of them is using Melinjo seed skin which has antibacterial power. The purpose of the study is to find out the activity of Melinjo seed bark extract (Gnetum gnemon) in inhibiting the growth of Salmonella enteritidis that can be used as a natural preservative in chicken meat. The first stage of the study was by extracting Melinjo seed bark using ethanol 96% with maceration method for 6 days. Activity test of Melnjo seed bark extract against Salmonella enteritidis using method of disc paper with a variation of the treatment of 25%, 50%, 75% and tetracycline positive control. The observed parameter is the measurement of the inhibited region Diameter (DDH) and the phytochemical test against Melinjo seed bark extract. The research results for the testing of the area Diameter of the hhibited region obtained the most effective concentration of 75% in the diameter of the area of the barrier of 10.3 mm and categorized with antimicrobial power levels of moderate sensitivity as well as can be used as natural preservatives in chicken meat. Phytochemical test results indicate the presence of compound flavonoids, tannins, saponins and triterpenoid.

Abstract

The apperance of acne is a problem for many suffers because can lower confidience and shame. Many people have attempted to treat or eliminate acne, that is by antibiotic. However of antibiotic clearly has side effects, and the ultilization of natural material is the solution. One of them is Padina australis which contains flavonoid, tanin dan saponin potentially as an antibacterial. The purpose of this research is to derermne the concentration of Padina australis extract with methanol 98% which has optimal activity in improving the growth of Propionibacterium acnes based on inhibition zone test and minimum inhibitory concetration (MIC). Qualitative phytochemical test were carried out on alkoloids, flavonoids, saponins, tannin and steroids. Testing these bacteria using disc dffusion methods. MIC of Padina australis extrct used dilution method with concentrtaion of 3.75%, 7.5%, 15% and 30%. Inhibition zone test used disc diffusion method with concentrtaion of 60%, 80% and 100%. The result of phytochemical screening testing Padina australis extrct test showed that there are secondary metabolite compounds alkoloids, flavonoids, saponins, tannin and steroids. MIC test of Padina australis extrct against Propionibacterium acnes occured at a concentration of 30% and the inhibition zone test was found at concentration of 100% which was the most optimal in inhibiting with an average of the inhibition zone width 6.20 mm.

Abstract

The success of this electrocoagulation method wastewater treatment is influenced by the voltage density and contact time. A reddish liquid waste treatment from the cosmetics industry has been carried out by batch electrocoagulation system. The research aims to determine the optimum voltage and time density conditions that can be the result of effective cosmetics liquid waste treatment by batch system electrocoagulation method. Reddish cosmetics liquid waste samples were taken from the cosmetics industry and analyzed the parameters of waste water quality including: pH; dissolved oxygen (DO); Chemical Oxygen (COD) requirements for Fe and Al metal content, and then waste treatment is carried out. A total of 0.5 liters of waste samples were carried out by electrocoagulation of a batch system using a one liter volume glass chamber using 1 mm aluminum plate electrodes measuring 5 cm x 10 cm effectively immersed, the distance between the electrodes was 5 cm. Both electrodes were given varying electric voltages: 9; 12; 15; and 20 volts DC and each with time variations: 15; 30; 45; and 60 minutes, the experiment was repeated twice. Electrocoagulation water is analyzed a number of quality parameters according to the initial analysis. The best treatment optimum conditions produce water quality: pH = 9.96; DO = 6.9 mg / L; COD = 280 mg / L (a decrease of 74.19%); TSS = 88 mg / L (a decrease of 86.21%); Fe = 0.31 mg / L (80.38% Fe decrease). The results of this electrocoagulation treatment meet wastewater quality standards according to Permen LH No. 05 of 2014 annex XLVII class II except pH ( 9.0)., And can be discharged by water bodies.

Abstract

Heavy metals in waters are a threat to living things both biota that are in these waters, as well as on plants and humans that depend on these water sources. Water quality improvement can be done by utilizing local gravestone (Pilsbryoconcha exilis) as a natural filter. In this study consisted of four treatments and three replications. The amount of gravestone weights of 200 grams, 300 grams and 400 grams acts as a treatment that will later be seen its effect on water containing arsenic metal. The results of this study indicate that local gravestone can reduce arsenic levels in waters with a treatment weight of 400 grams showed the best results with the final result arsenic level of 0.0101 ppm and the highest daily growth rate is 200 grams of weight treatment with a market value of 4.40%.
