Factors Influencing the Changes of Forest Cover (a Case Study on Sumatra Island)

In Indonesia, decreasing the forest cover or deforestation in 2000-2005 period had increased up to 1,09 million ha per year, and in Sumatera island alone the deforestationreached 0,27 million ha per year. The primary factors that caused the changes of forest cover in Sumatera are logging, both legal and illegal, and forest conversion for other landuses. This paper used panel data model for eight provinces in Sumatera from 2000 to 2006 to analyze direct causes of changes of forest cover. In the model of changes of forest cover caused by logging, resulted a positive correlation between deforestation and price of timber. These results implied that the rise of timber price made illegal loggers try to get maximum profit in a short time, and it could stimulate illegal logging. In the model of changes of forest cover caused by forest conversion for other land uses, the results showed a positive correlation between deforestation and GDP per capita. The result concludes that the increase of GDP per capita makes consumption for agricultural goods increase, and it can stimulate forest conversion for other land uses

BIODIESEL DARI HASIL SAMPING INDUSTRI PENGALENGAN DAN PENEPUNGAN IKAN LEMURU DI MUNCAR

Penelitian ini bertujuan untuk mengetahui kualitas biodiesel hasil transesterifikasi minyak ikan lemuru yang diperoleh dari hasil samping industri pengalengan dan penepungan ikan. Pembuatan biodiesel dilakukan secara kalatilitik melalui tahapan esterifikasi, transesterifikasi, pencucian biodiesel dan pemanasan. Transesterifikasi dilakukan menggunakan metanol dengan perbandingan molar minyak ikan dengan metanol sebesar 1:3, 1:4 dan 1:5. Pengujian biodiesel menggunakan standard SNI 04-7182-2006. Hasil pengujian menunjukkan bahwa densitas biodiesel pada suhu 40oC dan titik nyala pada berbagai perlakuan menghasilkan nilai yang sama yaitu 0,87 g/ml, dan 166 0C. Kandungan air dan sedimen juga menunjukkan nilai yang sama yaitu <0,05 % v/v pada berbagai perlakuan. Bilangan saponifikasi pada perbandingan molar minyak dengan metanol 1:3, 1:4 dan 1:5 masing-masing sebesar 182,16; 182,16 dan 181,16 mg KOH/g, kandungan gliserol bebas masing-masing sebesar 0,0037; 0,0051 dan 0,0031% w/w, sedangkan bilangan asam total pada perlakuan yang sama menunjukkan nilai masing-masing sebesar 0,189; 0,188 dan 0,189 mg KOH/g. Kandungan gliserol total pada perbandingan molar minyak dengan metanol 1:3, 1:4 dan 1:5 masing-masing sebesar 0,135; 0,138 dan 0,121 % w/w dan kandungan ester masing-masing sebesar 98,50; 98,51 dan 98,68 % w. Semua parameter kualitas biodiesel tersebut sesuai dengan persyaratan kualitas biodiesel pada SNI 04-7182-200

Eksperimentasi Model Pembelajaran Missouri Mathematics Project (Mmp) Dan Model Pembelajaran Student Teams Achievement Divisions (Stad) Disertai Assessment for Learning Melalui Teman Sejawat Ditinjau Dari Kemandirian Belajar Siswa Kelas X SMA Di Kabupaten

. The purposes of this study were to determine: (1) which has better learning achievement, students are given MMP learning model with AfL through peers, STAD with the AfL through peers, or students who were given direct learning model, (2) which has better learning achievement, students with learning independence of high, moderate or low, (3) on each learning model, which one has the better learning achievement, students with learning independence of high, moderate or low, (4) in each learning independence category, which has better learning achievement, students are given MMP learning model with AfL through peers, STAD with AfL through peers or students who given direct learning model. This study was a quasi-experimental study with a 3 x 3 factorial design. The study populations were all of grade X students of Senior High School in Bantul. Sampling was done by stratified cluster random sampling. The samples in this study amounted to 214 students with the details of 72 students for experiment 1 and 70 for experiments 2 and 72 for the control class. The data collected instrument used mathematics achievement tests and a questionnaire of student's learning independence. Based on the hypothesis testing, it can be concluded as follows. (1) Students' learning achievement treated by MMP learning model with the AfL better than students treated by STAD models with AfL and direct learning model. In addition, students' learning achievement treated by STAD model with AfL through peers better than students treated by direct learning model. (2) Students' learning achievement which has high learning independence better than students who have moderate and low independence. In addition, students who have moderate learning independence better than students who have low learning independence. (3) In the MMP learning model with the AfL through peers, STAD with AfL through peers and direct learning model, the students' learning achievement who have high learning independence better than moderate and low learning independence, in addition the students' learning achievement who have moderate learning independence better than students who have low learning independence. (4) In the learning independence category of high, moderate and low, the students' learning achievement treated by MMP with the AfL through peers better than students treated by STAD with AfL through peers and direct learning model. In addition, students' learning achievement treated by STAD with AFL through peers better than students treated by direct learning model
