The purpose of research (1) Investigate the effect of guided Inquiry learning toward student learning result (2) Investigate the effect scientific performance to the student learning result (3) Investigate the interaction the guided Inquiry model and learning scientific performance toward the student learning result in sistem Excretion material. The research subjeck were 60 student of XI IPA 1 and 2 of SMAN 10 Pandeglang. Taken by simple random sampling. The data were analyzed by two tailed ANOVA test. Before the hypothesis was tested, normality and homogeneity test were done, the method that used in this research is quasi experiment with 2 x 2 factorial design. Based on the analyzed data, the highest score of the student learning result in experiment and control group were 90 and 85 with the means were 82 and 72. It can be concluded that: (1) there is significant influence of guided Inquiry learning the student learning result (2) there is significant influence of scientific performance to the student learning result (3) there is an interaction between guided Inquiry learning model and scientific performance toward the student learning result in Excretion system material. Based on the conclusions, it is suggested that the teacher's ability is encouraged to dig deeper the student's potential and performance.

Penelitian ini bertujuan untuk mengetahui jenis-jenis tumbuhan paku terestrial yang ada di KHDTK (Kawasan Hutan dengan Tujuan Khusus), besarnya frekuensi dan frekuensi relatif tumbuhan paku terestrial, dominansi dan dominansi relatif tumbuhan paku terestrial, indeks nilai penting daritumbuhan pakuterestrial, dan indeks dominansitumbuhan paku terestrial. Metode penelitian yang digunakan adalah metode deskriptif dengan teknik purposive samplingdengan melihat komposisi jenis dan jumlah tumbuhan paku pada suatu area tertentu. Penelitian ini digunakan untuk mendeskripsikan keanekaragaman jenis paku yang ada di KHDTK (Kawasan Hutan Dengan Tujuan Khusus), Pandeglang, Banten. Pengamatan terhadap kondisi lingkungan meliputi intensitas cahaya, suhu lingkungan, kelembaban lingkungan, pH tanah, dan ketinggian tempat. Hasil penelitian yang diperoleh adalah ditemukannya tiga spesies pakupada KHDTK, yaitu Selaginella plana, Lygodium salicifolium,danDiplazium esculentum.INP tertinggi terdapat pada spesies Selaginella planadan terendah terdapat pada Diplazium esculentum.Selaginella planalebih dominan dibandingkan spesies lainnya yaitu Lygodium salicifolium danDiplazium esculentum.

Tujuan dari penelitian ini adalah untuk mengetahui hubungan komitmen dan tanggung jawab lingkungan terhadap kinerja pengelolaan hutan pada program reboisasi. Lokasi penelitian dilaksanakan di Resot Pemangku Hutan (RPH) Solokuro – Lamongan, dengan obyek penelitian adalah masyarakat desa Solokuro peserta program reboisasi. Pengumpulan data dilakukan dengan membagikan kuesioner kepada 75 responden sampel. Data yang terkumpul dianalisis dengan menggunakan statistik parametrik yaitu statistik deskriptif dan statistik inferensial. Pengujian hipotesis dilakukan melalui uji korelasional. Uji analisis dalam penelitian ini meliputi: (1) uji multiple (2) uji koefisien korelasi, dan (3) uji koefisien determinasi. Hasil penelitian ini menunjukkan, (1) komitmen yang tinggi berhubungan kinerja pengelolaan hutan yang tinggi, (2) tanggung jawab lingkungan yang tinggi berhubungan dengan kinerja pengelolaan hutan yang tinggi, (3) komitmen dan tanggung jawab lingkungan yang tinggi membuat kinerja pengelolaan hutan tinggi. Berdasarkan hasil penelitian tersebut bahwa komitmen dan tanggung jawab lingkungan baik sendiri-sendiri maupun bersamaan memiliki hubungan positif terhadap peningkatan kinerja pengelolaan hutan, sehingga model ini dapat dilanjutkan dan juga bisa diterapkan program reboisasi di lokasi yang berbeda.

The skills to think critically on environmental pollution material is the skills of the learners to understand a condition that involves the process of reasoning about environmental pollution. Student's critical thinking skills is an interaction between various factors, namely naturalist intelligence and motivation learning. Student who possess critical thinking skills are as good as those naturalist intelligence and those who are motivated to learn. This study aimed to determine the correlation between naturalist intelligence and motivation learning with student's critical thinking skills in Jakarta on environmental pollution. This research was conducted at 68 Jakarta Senior High School on semester II of 2017/2018 school year. The method that was used is descriptive quantitative through correlational study. The sample used amount if 115 students of class X MIA. The result of prerequisite test finds that the data are normally distributed and homogeneous. The statistical hypothesis was done by linier regression test, liniearity test, and correlation coefficient test at α = 0,05. Based on these results, it is concluded there is a correlation between naturalist intelligence and motivation learning with student's critical thinking skills on environmental pollution.

A serious environmental problem has occurred due to the negative impact of household waste. Lack of knowledge and awareness of waste processing must be improved through an effective counseling method provided for housewives. The aim of this research was to determine different counseling methods about garbage toward housewives’ knowledge about processing of the household waste. This research carried out on Kampung Pulo, Jakarta Timur on April 2013. A quasi-experiment method with a randomized control group pretest-posttest design was used. Counseling methods of demonstration and movie display were given in two different groups as the treatment. Instrument of knowledge test was used to collect data. The normality testing of Kolmogorov-Smirnov test and the Homogeneity testing of F-test at α = 0.05 resulted a normal distribution and homogenous data. The hypothesis testing of t-test showed t count > t table on 3.34 > 2.03 which rejected the H0, meaning that different knowledge level about processing of the household waste obtained from different method of counseling. It is concluded that, demonstration method was more effective than movie display to increase the housewives’ knowledge about processing of the household waste.
