DETERMINATION OF OIL AND FAT LEVELS IN LIQUID WASTE OF PALM OIL INDUSTRY IN MUARO JAMBI DISTRICT

Waste contains pollutants that can change the quality of the environment.Wastewater discharged into the environment must comply with standard quality standards. One of the parameters that are harmful to the environment are oils and fats. Oils and fats are on the surface of the water so they can block sunlight from entering the water and can interfere with the activities of aquatic biota. Determination of oil and fat content in palm oil industrial wastewater in Muaro Jambi District using the gravimetric method based on the Indonesian National Standard 6989.10:2011. The results obtained in the inlet waste pond of PT. A, PT. B and PT. C respectively 582.4 mg/L; 380.2 mg/L and 221.4 mg/L while for PT. A, PT. B and PT. C respectively 78.8 mg/L; 53.6 mg/L and 12.8 mg/L. According to the Regulation of the Minister of the Environment of the Republic of Indonesia No. 5 of 2014, the maximum permissible level for liquid waste oil and fat at the outlet liquid waste of the palm oil mill industry is 25 mg/L. Based on the test results, it can be concluded that the levels of oil and fat that meet the quality standards of palm oil liquid waste are outlet waste from PT. C

TRADISI PENYALINAN NASKAH ISLAM PALEMBANG: Ditinjau dari perspektif Ekonomi

Abstract: Why the lease on the script? The manuscript is one of the sources of knowledge that contains a variety of data, information, thoughts, feelings and knowledge of the history and culture of a particular nation or social group. It was written by a variety of literacy and local languages was produced. So many manuscripts scattered in the archipelago, but the study of this text can be said to be rare; this is caused by the use of language and script in a script that is difficult to understand. Therefore there should be a special review on this field. In general, the study of manuscripts made with emphasis on the comparison of the content of the text in terms of content. This paper does not discuss the content of the text as a whole, but merely reviewing the manuscript kodikologi aspects that are still not widely applied. This is done to know the history of the writing of various literary events nationwide especially on copying the manuscript tradition of Islam in Palembang. Through scriptorium / studio writing writing activities, writing traits and other activities that are part of the cultural history of a region. So the economic perspective will be seen here through reading kolopon available on the manuscript. Keywords: Manuscrift, penyalinan, sewa dan ekonomi.

THE EFFECT OF APPLYING CONTEXTUAL LEARNING TO SCIENTIFIC ATTITUDE ON ECOSYSTEM MATERIAL

Contextual teaching and learning (CTL) is a conception that helps the teacher link the subject content to realworldsituations and motivate students to make connections between knowledge and application in their lives.This study aims to describe the effect of applying contextual learning model to the scientific attitude of juniorhigh school students on ecosystem material. This research is quasi experiment and uses the Matching OnlyPosttest-Only Control Group Design. The implementation of this study include of 33 students as experimentalclass and 32 students as control class in one of junior high school at East OKU. The research instrument used inin the form of rubric assessment, questionnaire, and observation sheet. Data was analyzed by using MicrosoftExcel and SPSS program 16. The statically result showed that contextual learning model had an effect onimproving students ’scientific attitude so that they could reach the minimum criteria. This is because the studentcan learn the lesson material presented through the context of their lives, and find meaning during the learningprocess, so that learning will become more meaningful and fun with the ecosystem material. This learningmodel can improve students’ scientific attitude through the syntax contained in it. Keywords: CTL learning model, scientific attitud

THE EFFECT OF MIND MAPPING LEARNING STRATEGY TO STUDENTS’ LEARNING RESULT ON EXCRETORY SYSTEM MATERIAL AT XI CLASS

This study aims to determine the effect of mind mapping learning strategy on student learning outcomes onexcretory system material in XI Science class. The research method used in this research is quasiexperimental method with design non - randomized Control Group Pretest-Postest Design . The population inthis study includes all XI science class in senior high school which amounts to 60 students. The samplingtechnique used sampling saturated with class XI Science 1 which amounted to 30 students as experimentalclass and class XI Science 2 which amounted to 30 students as control class. The instrument used in thisresearch is written test in the form of pretest and posttest to measure student learning result cognitively. Thefirst stage data analysis of the average value of pretest in experimental class is 47.50 while the control class is49.50. After applying the mind mapping strategy , the average grade of post experiment class increased withthe average value of 83.33 which is very good while the mean score of posttest of control class is 73,2 which isgood. The calculation results are known that there is influence a significant application of mindmapping learning strategy to student learning outcomes.
