Abstract

Culex quinquefasciatus mosquito control can be performed at the larval stage using more environmentally friendly leaf of Spondias dulcis Forst. This study aims to determine the ability of extracts contained in the leaf S. dulcis Fosrt. as larvacide to larvae Cx. quinquefasciatus instar III. The study used Completely Randomized Design (RAL) with 6 treatments repeated 4 times. The treatment used was 125 ppm, 250 ppm, 500 ppm, and 1000 ppm with 2 controls, ie 0 ppm and temefos 1 ppm. Observations were made after 24 hours of exposure and data obtained in the analysis using one way ANOVA, to see the real difference used Duncan test, and Probit was used to calculate the LC50 value. The results obtained are the extract has the ability as a larvacide of killing by 92.50% at a concentration of 1000 ppm.

Abstract

Musi River Sungsang Village which is located near the settlement makes people throw garbage into the sea during high tides so that it will affect water quality and have an impact on macrozoobenthos. It is im-portant to know the diversity of macrozoobenthos in the waters of the Musi River in Sungsang Village, South Sumatra. This research was carried out from January 2018 to August 2018 in the Musi River in Sungsang Vil-lage, South Sumatra by using the method of direct observation and randomized group design. The research location was determined by purposive sampling method and divided into 4 stations, each station had 1 line transect and each line transect was taken as many as 10 samples. ANOVA, overley and correlation analysis are used to process data. Based on research conducted in the Musi River in Sungang Village, there were 14 ma-crozoobenthos taxa consisting of 3 classes: bivalves, gastropods and polychaeta. Index of macrozoobenthos di-versity in Musi River in Sungsang Village is classified as ranging from 0,000 – 1,733. Organic matter does not af-fect macrooobenthic in the Musi River in Sungsang Village, South Sumatra

Abstract

Pare is one of the plants used as an herbal medicine, one of which is for infectious diseases. This study aimed to evaluate the antifungal activity ethanol extract fraction leaves of Pare. The extraction was carried out using maceration method and then fractionated using n-hexane, ethyl acetate and water solvents. The antifungal activity was determined using the agar diffusion method. The test fungus was using Microsporum canis at a serial concentration of 1,5%, 1% and 0,5%. The results of antifungal activity test of n-hexane fraction, ethyl acetate fraction and water fraction of Pare leaf ethanol extract showed the existence of inhibitory zone diameter. In the n-hexane fraction, ethyl acetate and water frac-tion the diameter of the largest inhibitory zone was 11,7 mm, 11,6 mm and 10,1 mm. Inhibitory zone showed that the fraction of ethanol extract of Pare leaves has antifungal activity.

Abstract

This research aims to see the effect of adding some concentration of NPK fertilizer and acid mine drainage can improve phytoremediation process using Eleocharis dulcis. This research was conducted in Plant Physiology Laboratory of Biology Department of FMIPA Sriwijaya University, and Laboratory of Balai Teknik Kesehatan Lingkungan dan Pengendalian Penyakit Kelas I Palembang, South Sumatera. The design used in this research was a Randomized Block Design of a factorial pattern consisting of two factors: NPK fertilizer concen-tration (0 mg / L, 500 mg / L, 750 mg / L, and 1000 mg / L) and AMD waste (0% 25%, and 50%), each treatment combination was repeated 3 times. Data were analyzed by analysis of variance (ANOVA), mean difference be-tween treatments was done using Duncan Multiple Range Test (DMRT) test at α 5% level. The results showed Eleocharis dulcis at AMD concentration of 50% with addition of fertilizer 750 mg / L able to improve process of phytoremediation of AMD. E. dulcis was able to reduce good Mn concentration at AMD concentration 50% with addition of NPK fertilizer 750 mg / L that is 2.77 mg / L. Change of pH at concentration AMD 50% with addition of NPK fertilizer 750 mg / L that is 6,0. Dry weight of Eleocharis dulcis after phytoremediation at AMD concentration 50% with addition of NPK fertilizer 750 mg / L ie 13.58 g.

Abstract

This study aims to calculate the value of the abundance of macrozoobenthos in the Intertidal Musi River Estuary in Sungsang Village, Banyuasin II District, Banyuasin District, South Sumatra Province and to analyze the effect of water salinity on macrozoobenthos in Intertidal Musi River Estuary, Sungsang Village, Ba-nyuasin II District, Banyuasin District, South Sumatra Province. The study was conducted from January 2018 to August 2018, at the Laboratory of Ecology, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University, Indralaya. This study includes the test of morishita index and correlation. The results of the study were 4 genera from Bivalvia class, 4 genera from Gastropod class, and 2 families from Poly-chaeta class. The macrozoobenthos abundance in the intertidal Muara Sungsai Musi ranged between 456-854 ind/m2 and the morphic index of each station was included in the grouping and random criteria. Based on the analysis between abundance and salinity, the bottom coefficient (r) is equal to 0.943 which is very strong be-tween salinity and abundance.

Abstract

Kelas mamalia memiliki salah satu ordo yaitu kelelawar atau Chiroptera yang memiliki arti “sayap tan-gan”. Kelelawar masih sangat sedikit menjadi perhatian dunia biodiversitas, fungsi kelelawar dalam ekosistem adalah sebagai pengendali biologis, penebar benih serta untuk penyedia substrat makanan bagi ekosistem di-dalam gua. Penelitian sebelumnya yang dilakukan oleh Atmawijaya (2008) dengan menggunakan dua metode berupa mist net dan pengamatan langsung, dijumpai enam spesies yaitu Hipposideros larvatus, H. diadema, Eo-nycteris spelaea, Penthetor lucasii, Rousettus sp., dan Miniopterus sp. Namun pada penelitian ini yang menggu-nakan tiga metode berupa tangkap langsung, mist net,harp net dan pengamatan langsung, ditemukan empat spesies : Rousettus Sp, Megaderma Sp Miniopterus pusillus, dan Saccolaimus saccolaimus. Terjadinya penurunan jumlah spesies disebabkan oleh beberapa faktor berupa pembasmian kelelawar secara masif yang disebabkan adanya anggapan bahwa kelelawar adalah hama pertanian, kelelawar sebagai hama peternakan wallet, serta pengembangan wisata dan pembangunan di kawasan Gua Putri. namun faktor adanya anggapan bahwa kele-lawar adalah hama sangat bertentangan dengan fungsi kelelawar di ekosistem yang merupakan pengendali biologi, dan penebar benih. Kelelawar juga dapat hidup berdampingan dengan wallet di dalam gua.
