Abstract

Gelatin is a protein from the hydrolysis of bone collagen and skin of animals wich are widely used for industrial food and non food. Studies on extraction of gelatin from tuna (Thunnus sp) bone were carried out by soaking in hydrochloric acid solutions of 4%, 6% and 8% for 48 hours respectivelly and extracted with aquadest at 60ºC, 70ºC and 80ºC for 5 hours. The extract was filtered with filtering cloth and the filtrate was oven dried at 55ºC for ± 48 hours until gelatin was formed. The result showed that soaking the bone in 8% hydrochloric acid solutions followed by extraction 80ºC for 5 hours gave the best result with 8,64 yield, isoelectrict point 8,20%, protein contain 93,72%, lipid contain 0,74-1,75%. Gel strengh 257,59 g/bloom gel strengh, viscosity 3,20 cPs, pH 3,98. The results obtained for water contain of 6,97%. Ash countain 2,07%. The colour of gelatin produced from tuna bone showered different with commercial gelatin that is between yellowish brown to whitish yellow. Gelatin made from tuna bone has fishy odor whereas commercial gelatin has neutral odor.

Abstract

Pharmaceutical industry PT . Nusantara Beta produce drugs - drugs and drug classes classes Free Free Limited . Thus the need for a treatment for a review dispose of waste Which has a raw quality that corresponds to the applicable government regulations . Already QUALITY liquid waste is processed through the WWTP already meet the Liquid Waste Quality in accordance with Minister of Environment 51 / MENLH / 10/1995 . From the findings of the WWTP ON ANOVA test concentration of TSS and phenol NOT show the real difference between Station , ON parameter while the COD , BOD5 and Total N has the real difference between AT Namely Station Station 1 has the distinction Yang Against Station 2 and Station 3. QUALITY Parameter waters river TSS , total N and pH are in accordance with the raw water quality Government Regulation No. 82 of 2001 , based on aNOVA test stations are ON EACH waters show There are real differences between the stations.

Abstract

Completion of the transportation problems in the city of Pekanbaru currently only looked at in terms of congestion, but not touching insights from environmental aspects such as performance air pollution and noise levels. This research was conducted at the observation point road ahead Repair Tambusai lord Eastern Daihatshu, road Tuanku Tambusai West Side Mall SKA, North Soekarno Hatta street front retail outlets, street front Soekarno Hatta South Hotel Ibis Pekanbaru. V / C Ratio highest in the afternoon rush hour on the road ahead Tambusai lord Stations Daihatsu ie 0.86 pelyanan road performance E. Quality Standard ambient NOx emissions do not exceed the threshold of ambient quality standards, the NOx emission = 281.76 mg/m3. Quality Standard ambient CO emissions do not exceed the threshold of ambient quality standards, namely emission = 7456.79 mg/m3, the noise level over the limit of noise that is 71.41 dB (A). To balance the load reduction in pollutant emissions and noise levels at the flyover plan with the plan of special bus lane traffic volume assumptions have to move 25% of the transfer of the road users of private vehicles and motorbikes switch to using mass public transport vehicles ie Trans Metro bus Pekanbaru.

Abstract

The size of the fly population at the time of Salted Catfish production (SC) is one of theimportant problems that will have an impact on the health and deterioration of fish quality, as well ashaving an impact on socio-economic conditions. Flies are mechanical vectors for the transmission ofdiseases carried through microorganisms Staphylococcus aureus (S.aureus). To deal with this problemproducers use chemical insecticides which are sometimes used at inappropriate dosages, so that they willadversely affect human health and the environment. therefore it is used by Fragrant Pandan Leaves(FPL) which have chemicals as poisons for vectors and safe for humans. This study aims to identify thecontamination of S.aureus bacteria in SC from Penyasawan Village, to analyze the effectiveness of FPLextracts in reducing the number of flies in the process of drying the SC on product acceptance. Usingexperimental research methods, with RAL, it was carried out at the UPTD laboratory for fish diseasesand the water quality of the Kampar Regency Fisheries Service. Data were analyzed using the One-WayANOVA statistical test. The results showed that, for the most part Salted Catfish from PenyasawanVillage is identified contamination of Staphylococcus aureus bacteria. Pandan Wangi Leaf Extract caneffectively reduce the density of flies that perch during drying of Salted Catfish with the highestconcentration having the greatest resistance to the flies of flies. Salted Catfish soaked in Pandan Wangileaves are in demand by consumers

Abstract

Habitat of Asian giant honeybee (Apis dorsata) and the forest that surround it play an important role for the development of bees. For local, honey gathered from the bees has important role in enhancing people`s live hood. However, studies examine the interaction between the bees and its vegetation is limited. The objection of this study were to (1) determine the number of the sialang trees and (2) to eamine structure of vegetation along the Indragiri river, Riau. The data were collected using the observation method by establishing many observation plots. The data were processed and analyze using quantative descriptive. The results showed that the structure of forests along the Indragiri river are consisted of several types of sialang trees, namely jelemu, arau, and stone wood. The diversity of plants is considerably high, such as Melastoma malabatrichum, rubber, ferns, acacia, and rattan at the seedling level and Macaranga sp, durio sp, rubber and meranti at the weaning level. The vegetation is considered still in good condition for bees` hive. Forest vegetation is dominated by the types of meranti, rubber, and the araceae family which can be used for either habitat or bee forage for bees.
