Abstract

Pulp and paper industry is one of industry that is relatively much generate solid waste, oneof is the solid waste from the Waste Water Treatment Plant with activated sludge systems,known as biosludge. Biosludge output from the secondary clarifier portion is returned to theprimary clarifier and partly in landfills. Present day this untapped biosludge waste properly,potentially causing pollution as they contain chemicals and hazardous, cause odor and landhoarding unproductive. Present day pulp and paper industries generate solid waste(biosludge) among 3-4 % of the production capacity. In this research has been done the testof Toxcicity Characteristic Leaching Procedure (TCLP). Method TCLP analysis performed isa method of Glass JAR USEPA SW-846 Method 1311. TCLP analysis results for each ofthese metals concentrations in unit mg per liter samples are: arsenic (0.004), barium(0.122), boron (2.66), cadmium (0.011), chromium (0.003), copper (0.025), copper (0.051),mercury (0.0003), selenium (<0.001), silver (<0.001), zinc (0.084). TCLP concentrationswere below the TCLP standards contained in Regulation No. 18 and 85/1999. According tothe delisting hierarchy non hazardous and toxic waste by regulation number 85/1999, wastebiosludge pulp and paper categorized as non hazardous and toxic waste. Althoughcategorized as non hazardous and toxic waste, destruction of the future scenario will come tobe a concern. Given the heavy metals in the environment are not easily degraded and eventends to accumulate in the food chain through biomagnification. It can be harmful to humanhealth, the survival of other creatures and can cause damage to the ecosystem.

Abstract

This study analyzes the greenhouse gas estimation calculation for CO 2 and NO x (asNO 2 ) emissions. Estimation is calculated using the SANGEA application which is basedon the fuel gas consumption and composition for the combustion engine. The estimationcalculations are then compared with the results of on a direct measurement by using acontinuous emission monitoring system (CEMS.) Furthermore, the estimationcalculation is referred to some related regulations to see if it meets with the standard, toknow the quality levels or “tier” and reliability of the SANGEA application used, alsoto learn more on the strategy undertaken by emitters in managing GHG emissions. Thestudy methodology used is descriptive qualitative analysis by performing field survey tolearn how to perform direct measurements with continuous emission monitoringequipment or CEMS in place (in situ) and how to calculate estimation emissions usingthe SANGEA applications for the operation of combustion engines or turbines. Theresult of this study shows that there are differences result between the SANGEAcalculation and CEMS direct measurement, where the SANGEA calculation result is19.7 - 27.8% lower than the direct measurement and this difference result is still closewith the previous studies that have been done, 18.3 to 30.7%, which is becomes atheoretical reference for this comparison calculation and direct measurement study.

Abstract

The heart rate activities of nile tilapia (Oreochromis niloticus) (average±s.d. = 14.80±1.20 cm Body Length (BL), n = 20) were measured by electrocardiograph (ECG) at various speed (5.97-55.64 cm sec-1) in PVC made flume tank. The data of heartbeat rate were collected by oscilloscope and recorded by video camera for deep analyzing. The incremental of heart rate was analyzed by relative heart rate, i.e. heartbeat rate during exercise divided to heartbeat rate control. The result shows that the heartbeat rate of nile tilapiawas 46.75±1.13 beatsmin-1 in control. It was not change at swimming speed of 5.97-13.83 cm sec-1. The threshold of heartbeat rate was increased at swimming speed of 17.67-23.56 cmsec-1. The heartbeat rate was significant increase at swimming speed higher than 35.31 cmsec-1; it could reach 3.85 higher than control value. The heartbeat rate activities are deeply discussed in relation to the various swimming speed level in this paper. Abstrak Aktivitas detak jantung ikan nila (Oreochromis niloticus) (rata-rata ± sb.= 14,80±1,20 cm panjang tubuh (PT), n = 20) diukur dengan menggunakan electrokardiograf (EKG) pada kecepatan renang yang berbeda (5,97-55,64 cm det-1) di da-lam tangki berarus. Data detak jantung ikan dikumpulkan dengan menggunakan oscilloscope, serta direkam dengan menggunakan kamera video untuk analisis lebih rinci. Kenaikan laju detak jantung ikan nila dianalisis dengan menggunakan persamaan relative heart rate, yaitu detak jantung ikan sedang berenang dibagi dengan detak jantung kontrol. Hasil pengamatan menunjukkan detak jantung ikan nila sebagai control ialah 46,75±1,13 detak men-1. Detak jantung ikan nila tersebut tidak mengalami perubahan pada saat ikan berenang pada kecepatan 5,97-13,83 cm det-1. Detak jantung ikan nila tersebut mulai mengalami kenaikan pada saat ikan nila berenang pada kecepatan 5,97-13,83 cm det-1. Se-cara signifikan detak jantung ikan nila naik pada kecepatan renang lebih dari 35,31 cm det-1, kenaikan detak jantung tersebut bisa mencapai 3,85 kali lebih tinggi daripada nilai kontrol. Aktivitas detak jantung ikan nila yang berhubungan dengan kecepatan renang yang berbeda akan didiskusikan dalam makalah ini secara mendalam.

Abstract

A series of counseling and discussion activities with the community in Kampung Baru Sentajo, Sentajo Raya District, Kuantan Singingi Regency were carried out with the purpose to increase knowledge, understanding of environmental sustainability and community empowerment towards efforts to prevent river pollution by community activities themselves. This counseling activity was attended by 30 participants with occupational backgrounds such as teachers, civil servants, farmers, journalists, housewives, and fishermen. Meanwhile, their education level starts from elementary school level to bachelor degree. Analysis of measuring activity achievement used descriptive analysis and descriptive statistical calculations. The descriptive statistical calculation uses the ratio of participants to items taken with the total extension participants who attend as a community in Kampung Baru Sentajo, Kuantan Singingi Regency. The analysis results are presented in the form of a pie graph. The results of the evaluation of the activities showed that 89.9% of the people represented by the counseling participants who attended stated that the existence of rivers is very important for life. Meanwhile, another 11.1%, the existence of the river is important for themselves and for the livelihood of many people. As many as 66.7% of them realized that the river in their environment had changed greatly and 33.3% the condition of the river had changed. As much as 55.6% of all participants who attended this counseling activity, the material presented were useful. While 38.9% is very useful. The interesting thing was that there were 5.6% who stated that extension activities were useless. Even though there were 5.6% of participants who took part in the counseling activities provided were useless, all participants of the event had interesting (50%) and very interesting (50%) content. The hope of the participants is that this counseling can be carried out in every village in Kuantan Singingi Regency, especially in villages that are central to unlicensed gold mining (PETI) by involving all village officials. In addition, the participants also expect to get material on practical ways to reduce pollution by liquid waste.
