Abstract

Dengue fever with A. aegypti as its main vector is a lethal disease. One effort that can be done tocontrol the Dengue fever from spreading is to break the chain of A. aegypti’s life cycle at larvae stage. This study aims to determine the concentration of LC50-24 hours leaves extract of P. serratifoliaand the solvents of P. serratifolia leaves extract that gives best toxicity to inflict death on A. aegypti larvae. The study was conducted during June to September 2013. ANOVA results shows that methanol extract and n-hexane extract of P. serratifolia leaves give significant effect on mortality of A. aegypti larvae. The value of LC50-24 hours methanol extract of P. serratifolia leaves was 2.691,53 ppm whereas that of n-hexane extract was 2.818,38 ppm. Methanol extract of P. serratifolia leaves has more toxicity compared to n-hexane extract.

Abstract

The Lait lake is a lake that serves as a source of water, a place for fishing, a transportation route and a recreational spot that will affect the existing limnophytoplankton. This research aims to determine the composition, abundance and diversity of limnophytoplankton, as well as the physical-chemical conditions of the limnophytoplankton habitat in the Lait Lake. The study was conducted from August to December 2014. The sampling location was divided into six stations. The results of the research found 51 genera of limnophytoplankton that were included in five divisions (Chrysophyta, Chlorophyta, Cyanophyta, Euglenophyta and Phyrrophyta) and 6 classes (Bacillariophyceae, Chrysophyceae, Chlorophyceae, Cyanophyceae, Euglenophyceae, and Dinophyceae). The diversity index value (H’) of the limnophytoplankton in the Lake was included in the category of medium (1.2498-2.1353), and the dominance index (D) was low (0.1866-0.4601) and the evenness index (E) was medium (0.3804-0.6161). The physical-chemical condition of the body of water of the Lait Lake was still capable of supporting the life of the existing limnophytoplankton.

Abstract

The treatment of liquid waste from rubber can be done with a biofilter method, which is by using micro-organisms attached to the filter to help the process of organic material degradation. The changes that occur to the organic substance in the waste will affect the composition of microalgae and protozoa during the treatment process. The purposes of this research is to find out types of microalgae and protozoa, their abundance in the rubber waste water treatment plant, and the quality of waste during the treatment. The research was conducted from September 2014 until January 2015. The research was conducted on the laboratory scale through observation of the microalgae and protozoa growth. The findings indicates that there are 36 genera of microalgae and 7 genera of protozoa. It shows that the highest abundance in the group of microalgae belong to Chlorophyceae class, whereas protozoa group is in the Sarcodina class. The genus which is able to adapt well would survive during the waste treatment processing. The genus which survived during waste  treatment process from the microalgae group was Cyanidium and from the protozoa group was Arcella.

Abstract

Keanekaragaman cacing tanah pada suatu habitat dapat dipengaruhi oleh kondisi fisik kimia dan habitat tersebut. Penelitian mengenai keanekaragaman cacing tanah pada tiga tipe habitat di Kecamatan Pontianak Kota telah dilakukan pada bulan Desember 2012. Penelitian ini bertujuan untuk mengetahui keanekaragaman cacing tanah di Kecamatan Pontianak Kota dan faktor lingkungan yang mempengaruhinya. Plot sampling ditentukan secara acak sebanyak 5 plot berukuran 5x5 m2 pada setiap lokasi. Sampling menggunakan metode kuadrat berukuran 30x30 cm2 dan hand-sorting. Komposisi cacing tanah tertinggi terdapat di kebun langsat dan lahan terlantar sedangkan yang terendah di persawahan. Genus Pontoscolex memiliki kepadatan tertinggi sedangkan yang terendah dari genus Pheretima. Keragaman jenis tertinggi terdapat di lahan terlantar (H=1,2438) karena memiliki vegetasi yang beragam dan rapat. Keragaman terendah ditemukan pada lahan persawahan (H=0,6931), hal itu terjadi salah satunya akibat pemakaian pupuk dan bahan kimia pertanian secara intensif.

Abstract

Lizards are one of the group of reptiles belong to suborder Sauria with the greatest number of members on earth. This research aims to know the species of lizards of suborder Sauria and to know the environmental condition found in primary, secondary and Tembawang forests in the district of Sungai Ambawang. The research was carried out by using cruising method. The lizards seen and found were captured by usingsnare stick, pitfall trap, glue trap and direct capture. Morphological characters analyzed to identify the lizards were snout vent length and tail length. In three types of forests in Sungai Ambawang district, a total of 68 lizards of suborder Sauria were recorded, which consisted of 48 lizards from family Scincidae, 5 lizards of Gekkonidae, 3 lizards of Lacertidae, and 12 lizards of Agamidae. The result showed that the dominance index (C) in primary forest was 0,0865, secondary forest was 0,1046 and 0,1462 in Tembawang forest. Evenness index (E) of types of lizards was relatively low, with a value of 0,2248 in primary forest, 0,2644 in secondary forest and 0,2663 in Tembawang forest. The similarity index (SJ) in the three locations was around 0,5-1 where the three locations had the similarity in the species of lizards.

Abstract

The efforts that should be made to maintain the quality of fish is by using antimicrobial compounds, one of which is chitosan. The use of chitosan in this study was to determine the effect and optimum concentration of chitosan in maintaining the quality of mackerel (Rastrelliger kanagurta) from the microbiological and organoleptic aspects. The study used a Completely Randomized Design (RAL) with 3 variations of chitosan concentration is 1%, 2% and 3% dissolved in 1% acetic acid. The control used was acetate 1% solution and distilled weter. Observations were made after the fish are kept for 24 hours with the observation parameters of Total Plate Count (TPC), organoleptic and the fish pH. Based on the Analysis of Variance (ANOVA), the result showed that the administration of chitosan on mackerel did not significantly affect the value of TPC and organoleptic, but the increase in the total number of bacteria in mackerel was lower than without the provision of chitosan. Chitosan was also able to reduce the value of mackerel organoleptic lower than without the provision of chitosan. Mackerel stored for 24 hours at each treatment increased the pH 5 to 7, which shows that the fish has undergone a process of decomposition.

Abstract

Ammonia is naturally formed from the breakdown of proteins in the decomposition of organic waste. The aim of this research is to understand the level of ammonia in ambient air and in the blood of the gerbage collectors at TPA Batu Layang Pontianak, as well as their hematologic condition after the gas exposed. This research had been done from October to November 2013. The ammonia level measurement was done by using Indofenol method of 0.0223 – 0.0817 ppm. Both male and female gerbage collectors, who had been working for more than 5 years, had the highest ammonia in blood levels of 0.719 mg/l and 0.705 mg/l respectively. The result of the regression analysis showed that the gerbage collectors, who had worked for longer period, had the higher ammonia and the lower hemoglobin level in their blood. The ammonia in blood level also caused the defective erythrocytes membrane and the systolic blood pressure, so that it became unstable. The result also showed that erythrocytes have shape abnormality which is categorised as elliptocytes. A garbage collector, who had the lowest ammonia level (0.058 mg/l) had the damaged erythrocytes percentage of 12.13%. Whereas, the garbage collectors that had the highest ammonia level (0.719 mg/l) had the damaged erythrocytes percentage of 30.09%.
