Abstract

Indonesias forest is one of the centers of biodiversity in the world, where Indonesia is the third of seven countries called mega diversity country. The high rate of deforestation is causing the failure to achieve forest sustainability. It is reinforced by the presence of illegal logging. Illegal logging is a major cause of deforestation in Indonesia, which reached a level speed of 1.6 - 2.0 million hectares per year. That is why the Ministry of Forestry Indonesia has put the eradication of illegal activity including illegal timber trade. This study was conducted to identify why illegal logging is difficult to stop, and what are the impacts caused by illegal logging on the physical and biotic environment.This study is a literature study and case studies, in order to identify why it is hard to stop illegal logging and also the impacts caused by illegal logging on the physical environment and biotic environment.It is showed that illegal logging is symptoms that arise due to the highly complex issues involving multiple parties from different layers. Illegal logging has become a national issue which the commitment of governments at the national level must be real. However, because this problem occurs at the local level, then the commitment should also be clear areas in which Local Government must have a real responsibility. In general, the problems that led to illegal logging can be grouped into: supply-demand imbalance; government policies that are less precise; multi-dimensional crisis; excesses of decentralization (regional autonomy), and moral forces. A loss due to illegal logging has a broad dimension not only to economic problems, but also to social, cultural, political and environmental. In connection with the problems above , there are some required actions and commitments that must be implemented in an integrated and simultaneously involving the various parties involved stakeholders. Key Word: Illegal logging, Sustainability, Environment

Pembimbing Abdul Rasyid Saraha dan Fitriana Ibrahim. Penelitian ini dilakukan untuk mengetahui Pengaruh Penerapan model Problem Based Learning (PBL) berbantuan media Prezi terhadap efektivitas belajar siswa SMA Negeri 4 Kota Ternate pada Materi Titrasi Asam Basa dan besar pengaruh penerapan model Problem Based Learning (PBL) berbantuan media Prezi terhadap efektivitas belajar siswa SMA Negeri 4 Kota Ternate pada Materi Titrasi Asam Basa. Jenis penelitian ini adalah penelitian eksperimen menggunakan design penelitian One Group Pretest-Posttest Design. Populasi dalam penelitian ini adalah seluruh siswa kelas XI IPA SMA Negeri 4 Kota Ternate pada tahun ajaran 2022/2023 yang berjumlah 31 siswa yang terdiri hanya satu kelas. Teknik pengambilan sampel yang digunakan ialah sampel jenuh atau semua populasi dijadikan sampel, dengan jumlah sampel 31 siswa. Instrumen tes yang digunakan dalam penelitian ini berupa soal essay yang berjumlah 12 item yang digunakan untuk menghitung evektifitas belajar kognitif siswa. Teknik analisis data adalah teknik analisis statistik deskriptif dan analisis statistik inferensial menggunakan SPSS For Windows Version 21.0.

Besar pengaruh model PBL berbantuan medaia prezi terhadap efektivitas belajar siswa diperoleh dari nilai gain 0,84 (kategori tinggi).Kata Kunci : Efektivitas Belajar, Problem Based Learning, Titrasi Asam Basa AbstractThe effected of applying the Problem Based Learning (PBL) model with the helped of Prezi media on the learning effectiveness of students at SMA Negeri 4 Kota Ternate on Acid-Base Titration Materials. Advisors Abdul Rasyid Saraha and Fitriana Ibrahim. This study was conducted to determine the effect of applying the Problem Based Learning (PBL) model with the helped of Prezi media on the learning effectiveness. This type of research was an experimental study using a research design of One Group Pre-test Post-test Design. The population in this research were all students of class XI IPA SMA Negeri 4 Kota Ternate in the academic year 2022/2023, totaling 31 students consisting of only one class. The sampling technique used is a saturated sample or all of the population is sampled, with a sample of 31 students.

Data analysis techniques are descriptive statistical analysis techniques and inferential statistical analysis using SPSS For Windows Version 21.0. The results of the hypothesis test in this research obtained sig 0.05 or 0.000 0.05, tcount t table or 21,142 2,042 then Ha is accepted and Ho is rejected. The large influence of the PBL model assisted by the media prezi on the effectiveness of student learning is obtained from the gain value of 0.84 (high category). Keywords:Learning Effectiveness, Problem Based Learning, Acid Base Titration.
