The purpose of this study was to determine the effect of the PQ4R Learning strategy (Preview, Question, Read, Reflect, Recite, Review) on the learning outcomes of Integrated Science in Islamic Education in Biology learning. This research is a quasi-experimental study using the Posttest-Only Control Design design while data collection is done using a test instrument. The sample of the study was class VIII C (experimental class) totaling 28 students and class VIII D (control class) totaling 28 students. The research data obtained the highest score in the experimental class was 92 and the lowest score was 44 with an average of 72, while in the control class the highest score was 80 and the lowest score was 40 with an average of 63.57. Based on the calculation using the t test obtained thitung = 2.77 and at a significant level of 5% obtained ttable = 2.01 and a significance level of 1% t table = 2.68 thus 2.01 <2.77> 2.68. So that Ha is accepted, meaning that there is a significant influence on the results of Integrated Science learning of students who use the PQ4R learning strategy (Preview, Question, Read, Reflect, Recite, Review) in the Madrasah Tsanawiyah.   Keyword: Student learning outcomes, PQ4R learning strategy (Preview, Question, Read, Reflect, Recite,Review)   Abstrak. Tujuan Penelitian ini adaah untuk mengetahui pengaruh strategi Pembelajaran PQ4R (Preview, Question, Read, Reflect, Recite, Review) terhadap hasil belajar IPA Terpadu di Madrasah Tsanawiyah pada pembelajaran Biologi. Penelitian ini merupakan penelitian quasi eksperimen dengan menggunakan desain Posttest-Only Control Design sedangkan pengumpulan data dilakukan dengan menggunakan instrumen tes. Sampel penelitian adalah siswa kelas VIII C  (kelas eksperimen)  berjumlah 28 orang siswa dan siswa kelas VIII D (kelas kontrol) berjumlah 28 orang siswa. Data hasil penelitian di peroleh skor tertinggi di kelas eksperimen adalah 92 dan skor terendah 44 dengan rata-rata 72, sedangkan pada kelas kontrol diperoleh skor tertinggi 80 dan skor terendah 40 dengan rata-rata 63,57. Berdasarkan perhitungan menggunakan uji t diperoleh thitung= 2,77 dan pada taraf signifikan 5% diperoleh ttabel = 2,01 dan taraf signifikansi 1% ttabel= 2,68 dengan demikian  Sehingga Ha diterima, artinya bahwa terdapat pengaruh yang signifikan terhadap hasil belajar IPA Terpadu siswa yang menggunakan strategi pembelajaran PQ4R (Preview, Question, Read, Reflect, Recite, Review) di Madrasah Tsanawiyah.   Kata kunci: Hasil belajar siswa, startegi pembelajaran PQ4R (Preview, Question, Read, Reflect, Recite, Review)

The rise of the batik industry in Jambi Province causes the accumulation of waste in the environment. Disposal of batik dye wastewater directly into the environment is one source of heavy metals entering the river. Palm Oil Fuel Ash (POFA), as a part of waste originating from combustion residues of oil palm, is potential to be used as a low-cost adsorbent in overcoming the batik dye wastewater problem. The POFA is also potential to be used in the removal of heavy metals and chemical and organic compounds in industrial waste treatment. This paper reported the potential use of POFA and the modification of POFA as batik dye adsorbents in overcoming waste problems from the batik industry. Results of this study showed that POFA could adsorb the dye in batik waste with up to 22% removal efficiency and adsorption capacity up to 62 mg/g. The isotherm adsorption in this study was in accordance with the Freundlich model that showed adsorption occurred at multi-layer and heterogeneous surfaces. The adsorption process occurred endothermically and spontaneously.

People still queue crammed when they get health services. Queues are generally carried out by cramming and mixing between male and female. This phenomenon has a very unfavorable impact for women. For this reason, policy makers must pay more attention to facilities and infrastructure to support gender equality. This study aims to see the extent to which the availability of facilities and infrastructure to support health institution services, especially hospitals in Jambi and how hospital policies regarding the implementation of government policies are related to gender equality. This study used a combination research method (mixed method research) with a sequential type explanatory strategy. Data collection techniques using quantitative techniques followed by qualitative techniques. The sample in this study were three government hospitals in Jambi. The sample was taken by using purposive sampling technique. The data collection instruments used observation, questionnaires, interviews and documentation. The data validation was done by using triangulation technique. The data analysis technique uses a mixed method technique. Quantitative data analysis using a percentage and a scale of 100 followed by qualitative analysis. This study found that hospitals in Jambi have sufficient status to meet the standards of supporting gender equality. The percentage value amounted to 48.73% of the 13 parameters of the facilities and infrastructure studied. These results indicate that the implementation of government policies in support of gender equality has not been fully realized and requires monitoring from the government.
