Profil Hematologi Pekerja Operator PT. PLN Sektor Kapuas PLTD Sungai Raya Pontianak
Get PDFDiesel Power Plant (PLTD) is an industry that uses diesel machines as electrical energy plant source. The machines which in PLTD create the sound intensity that exceeds the threshold value which can lead the workers to physiology stress. This research aims to determine the intensity of machines sound noise and hematological profile of PLTD operator workers differences that exposed to the sound of Sungai Raya PLTD machine based on their working period. This research was conducted from October to December2015. Samples which taken as many as 25 operator workers and 6 people carriers as control. The results showed that workers who exposed to machines sound while in the operator room of 80.84 dB and in the engine room of 105.24 dB. The intensity of diesel machines sound in engine room exceeds the threshold value of 85 dB that stipulated in the Decree of the Minister of Environment No. 48 of 1996. Operator workers with working period of 0-5 years has the number of leukocytes, LED level, the percentage ofneutrophils and monocytes higher compared to the control group and a longer working period. In contrast, the number of erythrocytes, hemoglobin levels and lymphocyte percentage of the operator workers 0-5 years lower than in the control group and the other working period. The percentages of hematocrit, eosinophils and basophils operator workers are no different to the control group and other working periods.Workers with longer working period have a body function that has been adapted to the working environment
Aktivitas Antibakteri Ekstrak Metanol Buah Ketapang (Terminalia catappa Linn.) Terhadap Pertumbuhan Staphylococcus epidermidis Dan Salmonella typhi
Get PDFThe most commonly found disease causing microorganisms are the Staphylococcus epidermidis and Salmonella tyhpi bacteria. These bacteria can be controlled by using natural antibacterial ingredients, one of which is the fruit of ketapang (T. catappa). This research aimed to find out the antibacterial intensity of methanol extract of the T. catappa fruit in inhibiting the growth of S. epidermidis and S. typhi. This research used the disc diffusion method. The extract was given treatments with 25%, 50% and 75%, both positive and negative control treatments. Each treatment was inoculated with a bacterial suspension, and then the filter paper that had been soaked in the extract was aseptically placed on the surface of the media, incubated with a temperature of 370C for 24 and 48 hours, then the area of clear zone around the filter paper was observed and meassured. The research findings showed that the fruit of T. catappa had an inhibitory effect against both bacteria tested. The extract of the fruit of T. catappa at the concentration of 50% was found to be the optimum concentration for inhibiting S. epidermidis and S. typhi

This research was conducted for five months from January to May 2015. The research used a completely randomized design (CRD) with a factorial pattern which consisted of two factors, i.e. bean sprout extract (A) with a concertration of 0%(A0), 5%(A1), 10%(A2) and BAP (B) with a concentration of 0 M (B0), 10-5 M (B1), 10-6 M (B2) each factor was combined and each combination was repeated three times. The research findings showed that the treatment A0B1 had a significant effect on the number of buds and leaves. The average of buds produced was 5,44 and the average number of leaves was 25,78
Penggunaan Kalium Permanganat (KMnO4) Untuk Menunda Pematangan Buah Pepaya (Carica papaya L. var. Bangkok)
Get PDFPapaya fruit (Carica papaya L.) is one of the horticultural products that contains a high nutritional value. The Papaya generally is easily damaged, so it is necessary to delay its ripening to maintain the quality. One of the methods of delaying the ripening of papaya is by using KMnO4 with absorbent material of sawdust. This research aimed to find out the influence of KMnO4 as the material for delaying papaya ripening. The research was conducted from March 2015 until May 2015 in the Laboratory of Biology, Faculty of Mathematics and Natural Sciences, and the Laboratory of Agricultural Produce Technology, Faculty of Agriculture, Tanjungpura University Pontianak. The research used a Completely Randomized Design (CRD) consisting of 6 treatments with a concentration of KMnO4 at0 ppm (A0), 60 ppm (A1), 75 ppm (A2), 90 ppm (A3), 105 ppm (A4) and 120 ppm (A5). The research findings indicated that KMnO4 at 60 ppm treatment affected the period of fruit storage for 12 days, with a weight loss of 7.56% and fruit glucose level at 5.096%

Get PDFThe tomato (Solanum lycopersicum L.Var. Permata) is one of the horticultural crops that contain vitamin C with potential for health. During the ripening process in storage, the tomato will experiencea more rapid weight loss and decay caused by respiration and bacteria. The storage life of the tomato can be extended by adding edible film from plant extracts that contain secondary hydrocolloid and metabolite compounds. This research aimed to find out the effect of the bandotan (A. conyzoides L.) leaf extract of different concentrations on the freshness of the tomato (S. lycopersicum L.) and to find out the best concentration of the bandotan (A. conyzoides L.) leaf extract to maintain the freshness of tomato (S. lycopersicum L.). The research was carried out from February to April 2015. The experiment used in this research was a completely randomized design. The concentrations of the bandotan extract used consisted of 4 treatments i.e. 0 ppm (P1), 10 ppm (P2), 20 ppm (P3) and 30 ppm (P4). The research findings indicated that the 30 ppm treatment was better at a weight loss parameter of 8.67 and a density of bacteria at 70.5 x 103. The treatments of 10 ppm, 20 ppm and 30 ppm had the ability to maintain the content of vitamin C
