Abstract

The aim of this study was to assess the percentage of local duck spermatozoa morphology (Anas platyrhynchos) for 6 days of storage in three storage mediums combining various egg yolk (EY) concentrations.This experimental study applied three combinations of factors as treatment. Medium (Tris, PBS or Ringer lactate), egg yolk (EY) concentration 0,5,10,15 or 25% and storage time (0,1,2,3,4,5,6 day). Spermatozoa obtained by sequence method, ejaculate or sperm obtained in swim up in medium, swim up spermatozoa were used for treatment in storage medium according to treatment and assessed before and after morphology of storage in refrigerator temperature (50 C). The results showed that spermatoza morphology was significantly different (P <0.01) between 15 treatments. The medium factor and concentration of EY significantly (P <0.05) affected the morphology of treatment spermatozoa. The highest percentage of highest post-preservation spermatozoa morphology for six days was obtained in 5% yolk treatment in PBS medium (5EYPBS). This study proves that egg yolk cryoprotectants are good for maintaining the morphology of local duck spermatozoa.

Abstract

Research on the estimation of green turtle population (Chelonia mydas) was conducted in Jemur Island of Rokan Hilir Regency of Riau Province in May-June 2012. The purpose of this research is to estimate the green turtle population in Jemur Island Rokan Hilir regency, Riau Province. The research method used is the absolute method of absolute sampling that results in the number of population estimates in the form of the number of individuals per unit of sand surface units or habitats observed. The results showed that the number of different individuals as many as 229 nests. The condition of Jemur Island indicates the suitability of location for green turtle habitat to lay and incubate eggs. Physical factors corresponding to the distribution of saraang are said to be productive, ie the average number of nests per day of 8 (eight) nests or 8 (eight) different individuals. Of the 229 nests observed, the depth of the hive ranged from 60cm - 80cm and did not significantly affect the number of eggs placed with the results of correlation (r = 0.43).

Abstract

This reseach aims to know the contamination of plastic materials that exist in market snacks (fried banana, fried tempe, fried tofu and bakwan goreng) that circulated in Medan City. This research uses the method of "Qualitative Description" that is by checking the plastic content in market snacks (gorengan) circulating in Medan City. The results of this study contained 12 positive samples contaminated with plastic materials and 48 samples were not contaminated with plastic materials. Plastic contaminated samples are tested by burning, if positive samples containing plastics will burn and a large flame is visible, black droplets and smell of burning plastic.

Abstract

This reseach aims to determine the presence of Salmonella sp. In chicken meat sold in both markets. The study was conducted by taking samples of chicken meat in each market as much as 50 grams. In the Sukaramai market, samples were taken from three locations, namely location I, II, III and one location from Carrefour supermarket. The bacteria contamination test was performed by counting the number of bacteria each sample with Plat Count Agar (PCA) method, each sample was diluted and cultured on 10-1 dilution. Deuteronomy is done four times. Then proceed with biochemical test. The results showed that all four samples of Salmonella sp. From Sukaramai traditional market contaminated with pathogen bacteria with the average amount of Salmonella as much as 1.7 X 102 from the overall location I, II, and III and also found contaminant bacteria that can be a pathogen while from Carrefour supermarkets not found Salmonella.

Abstract

Shallots and onions are one of the leading vegetable commodities consumed by the public. The supply of these two onion varieties in Indonesia is not available at all times because is done seasonally. Therefore it is necessary to increase the cultivation, one of which is through the addition of nitrogen through plasma technology. This study to determine the effect of giving plasma nitrogen through plasma technology to the growth of bima onion brebes and grano onions. The study used a Completely Randomized Design (CRD) consisting of 6 treatments with 5 replications. Plasma radiation is carried out on onion seeds and onions with a radiation interval of 15 and 30 minutes. The growth parameters observed were shoot growth time, growth percentage, root length, number of roots, plant height, number of shoots, and nitrogen content. Data were analyzed using ANOVA followed by DMRT Test at 95% confidence level. The results showed that the onion irradiated by plasma for 15 minutes could increase growth and total nitrogen content, while in onions, the highest yield was precisely in the control treatment (0 minute radiation). In onions, plasma administration can inhibit growth and total nitrogen content 0,31%, but can increase the number of roots.

Abstract

This study aims to determine the effect of concentration of base to ester hydrolysis products. Ester can dihidroisis with an alkaline catalyst at different concentrations. In this study, the concentration of metal acetate used was 1 M NaOH while coud concentration was 0.5 M, 0.75 M, 1 M, 1.25 M. The hydrolysis reaction using ethanol and refluxed for 2 hours at room temperature. Hydrolysis of methyl acetate ester compounds produced methanol with purity varies by different concentrations of methyl acetate and NaOH. At concentrations of 0.5 M NaOH acquired 79.5068% purity methanol, 0.75 M NaOH concentration 85.6665% purity methanol, 1 M NaOH concentration 99.6311% purity methanol and NaOH concentration of 1.25 M purity methanol 100,0000 %. Based on the results of the hydrolysis product purity shows the influence of the concentration of NaOH to the product ester hydrolysis. Methanol compound structure was analyzed by an infrared spectrometer and a mass spectrometer.

Abstract

The controlled landfill method can produce leachate water. Leachate water has high potential to contaminate ground water. The cadmium (Cd) can spread into the soil through a process of impregnation that follows the movement of groundwater flow. The purpose of this study was to analyze the relationship between the distance and well construction with cadmium content in the well water dug around the landfill. This research was an observational analytic research with cross sectional research design. The data collection method used in this research were observation, measurement, documentation and laboratory test. The result of laboratory test showed 80% of the wells exceed the quality standard (0,005 ppm). The result of bivariate analysis using chi square test showed that there was no correlation between the distance with cadmium content in dug well water around landfill (sig = 0.173) and there was a relation between well construction with cadmium content in dug well water around landfill (sig = 0.035). The good standart construction of dug well can inhibit the cadmium in the dug well water.
