The study was aimed to determine the influence of the use of student worksheet (LKPD) based on Predict Observe Explain (POE) strategy on student learning outcomes in the light material. This research was an experimental study with the design of experimental quasi using the form of a one-group pretest-posttest. The population of this study was the eighth-grade students of junior high school (SMP). Data analysis techniques were tested with the learning result grouping techniques, N-Gain analysis, hypothesis testing, linear regression tests, t-test paired test and effect size tests. The result of the N-Gain was a value of 0.60 with a moderate N-Gain interpretation. Linear regression test result was obtained a coefficient value of 0.7, with the sig regression value of 0,0. The result of the paired t-test achieved a significance value of 0.0, which indicated that there was a raise prior and following treatment. The result of the effect size test was 0.31 with a medium interpretation. The learning outcomes for psychomotor learners had an average value of 3.52 with excellent interpretation. Based on these findings, it can be concluded that the POE strategy-based LKPD was considerably effective to be applied in schools resulting in an increasing effect of the students learning outcomes before and after the treatment of POE-based LKPD.

Macang (Mangifera foetida L.) has potential as an effect herbal medicinal plant with antioxidant content, namely mangiferin. The aim of this study is to prove empirically study that macang has an immunomodulatory effect through preclinical testing. This study use white mice (Rattus norvegicus) as experimental animals and Staphylococcus aureus as test bacteria. Rats were give leaf extracts of 3 varieties of orally for 7 days using 3 prescribe doses in ppm. On the 8th day, each rats was induce by an intraperitoneal section with 0,5 ml of the bacterial suspension tested. Observation of peritoneal fluid through smear preparations includes 2 parameters, phagocytosis activity and capacity. The result showed that the immunomodulatory effects on batu varieties were effective at dose 2 (10 ppm = 0,01 mg/g), limus varieties and manis varieties were effective at dose 1 (1 ppm = 0,001 mg/g). According to this research, it was concluded that leaf extracts of three varieties macang could be used as immunomodulators.AbstrakMacang (Mangifera foetida L.) mempunyai potensi sebagai tumbuhan obat herbal dengan kandungan antioksidan yaitu mangiferin. Tujuan penelitian ini adalah membuktikan efek imunomodulator pada tiga varietas macang (batu, limus dan manis) melalui uji praklinik. Penelitian ini menggunakan tikus putih (Rattus norvegicus) sebagai hewan uji dan Staphylococcus aureus sebagai bakteri uji. Tikus diberi ekstrak daun tiga varietas macang secara oral selama tujuh hari menggunakan tiga serial dosis dalam satuan ppm. Pada hari ke-8, setiap tikus putih diinduksi bagian intraperitoneal dengan 0,5 ml suspensi bakteri uji. Pengamatan cairan peritoneal melalui preparat apusan meliputi 2 parameter yaitu aktivitas dan kapasitas fagositosis. Hasil penelitian menunjukkan bahwa efek imunomodulator pada varietas batu efektif pada dosis 2 (10 ppm=0,01 mg/g), varietas limus dan manis efektif pada dosis 1 (10 ppm=0,001mg/g). Disimpulkan bahwa daun macang (Mangifera foetida) berpotensi digunakan sebagai imunomodulator.Kata kunci : Fagositosis makrofag, Imunomodulator, Mangifera foetida

The environmental problem-solving skill is influenced by many factors, including ecological literacy. This study aims to analyze the relationship between ecological literacy and environmental problem-solving skill in the Adiwiyata school of Tangerang City. The research method that used was quantitative descriptive with survey technique. The number of respondents consisted of 245 students of grade 11th Science from three Adiwiyatas' Senior High Schools in Tangerang City. Ecological literacy was measured by using test and questionnare, while the environmental problem-solving skill was measured using an essay test. The results showed that there was a weak positive relationship through the regression model Ŷ = -18,084 + 0,877X. The correlation coefficient obtained was 0.382 and the determination coefficient was 14.6%. The higher score of the ecological literacy, so the students' environmental problem-solving skill will be better. Based on the results of the study, other schools also need to implement Adiwiyata programs in order to ecological literacy and students' environmental problem-solving skills could be better.ABSTRAKKemampuan memecahkan masalah lingkungan dipengaruhi oleh berbagai faktor, termasuk literasi ekologi.

Perspektif Pengajaran Teori Intelligent Design di Sekolah Menengah Atas Mardiyyaningsih, Asriah Nurdini
Jurnal Pendidikan Matematika dan IPA Vol 3, No 2 (2012): Juli 2012
Publisher : Universitas Tanjungpura

Teori Intelligent Design (ID) merupakan teori tantangan terhadap teori evolusi yang diperkenalkan pada tingkat sekolah menengah. Tulisan ini mengkritisi mengenai perlunya perspektif pengajaran teori ID yang tepat sehingga mencegah pemberian pesan pembelajaran sains yang keliru, pada tiga ranah yaitu perbedaan fundamental antara teori ID dan evolusi, adanya proporsi pengajaran teori ID yang mendominasi arah penjelasan evolusi dan adanya intervensi agama dalam mendukung pembuktian sains dalam evolusi. Tulisan ini juga mengajukan pola pembelajaran yang menekankan pada kemampuan berpikir kritis dan debat sebagai solusi cara pengajaran teori ID di SMA. Pada akhirnya, dapat disimpulkan bahwa teori ID dapat diajarkan di sekolah dengan membatasi pada paparan saintifik terkait bukti-bukti ilmiah dan menghindari bukti teologis serta dengan mengedepankan kemampuan berpikir kritis dalam menganalisis bukti-bukti saintifik dalam kaitan menerima teori ID atau sebaliknya mempertahankan teori evolusi.
