This research is motivated by students' chemical mastery in learning is still low, especially for abstract concept/theory material. This can be seen from students being less active and lacking memory in following the learning process. In addition, schools only rely on textbooks that make students less interested in learning and there is no student workbook to support students' understanding. This research aimed at knowing the appropriateness of the instructional media design in the form of Probing-Prompting based student workbook on Periodic System of the Elements lesson. It was administered at State Islamic Senior High School 1 Pekanbaru. It was R&D (Research and Development) with 4-D model, and it was limited to 3 models—define, design, and development. The subjects of this research were the experts of material, the experts of media, and the experts of language, Chemistry subject teachers, 10 students at the tenth grade of MIA 1. The object was Probing-Prompting based student workbook on Periodic System of the Elements lesson. The research findings showed that Probing-Prompting based student workbook was appropriate to be used and it was based on the results of validity and practicality levels. The percentage of validity level obtained was 85.78% (very valid) and the practicality level was 85.33% (very practical). Based on theses results, it could be identified that Probing-Prompting based student workbook could be tested further. KeywordsStudent Workbook, Probing-Prompting, Periodic System of the Element

Clay is natural mineral from silicate family like crystal which has approximately 2 micrometer. There are two component unit of atom in clay mineral. One consists of oxygen or hidroksida with alumunium, iron or magnesium that coordinated in octahedral system. Others, it is tetrahedral system from silicon with oxygen or hidroksida. Based on IR analysis, it can be known that metal─OH bending vibrations it can be seen at 912,3 cm─1 wavelength. On the other bands between 694,3 and 754,1 cm─1 that are Si─O bending vibrations. X-Ray Diffraction (X-RD) analysis be seen main peak at 2 = 5,70o (d001=15,48 Å) and 2 = 20,02o (d001=4,43 Å). That are for smectite mineral kind montmorillonite as main unit in clay from Pacitan

It has been successfully synthesized a new pillared clay adsorbent by using natural bentonite from the Kecamatan Tulakan Pacitas East Java. The synthesis was carried out by intercalation methode by mixing benzalkonium chloride surfactant solution and precursor solution of iron chloride into natural bentonite solution, then the resulted solid phase was calcined at 400oC. The natural bentonite and the adsorbent of pillared clay were characterized by using infra red spectrosphotometer. The iron oxide content was determined by using atomic absorption spectroscopy. It has been concluded that pillarization proses increased the iron oxide content up to five time depending on the mole ratio of iron and cation exchange capacity (CEC) value of natural bentonite. From infra red spectra, it has been concluded that surfactant intercalation into inter layer space can be observed by using peak at 2925.8 and 2852.5 cm-1, while the iron oxide pillared is not observed.

AbstractThis research is motivated by the exam questions in the odd semester of 2015/2016 of which items have not been analyzed. Furthermore, the test result of the odd semester is under the minimum completion criteria. This document analysis research is aimed at discovering the quality of question items qualitatively and quantitatively. The result of the study suggests that 40 items of the odd semester chemistry subject exam questions are not qualitatively compliance with all material aspects, constructions, and the language examined from class 10 of Islamic Senior High School Ponpes Khairul Ummah. Furthermore, at MA Nurul Falah, there are 19 items which are not compliance with the aspect of materials, constructions, and the language that is examined. Quantitatively, there are 29 valid items at MA Ponpes Khairul Ummah and possess test reliability as many as 0.65. At MA Nurul Falah there are 31 valid items and possess test reliability as much as 0.76. Keywords: Analysis of grain problem, chemistry, qualitative, quantitative

Research on new university student misconceptions about bond in NaCl compounds has been done to identify possible misconceptions. Student misconceptions are observed using a misconception analysis instrument consisting of statements accompanied by right and wrong choices and open reasons. Based on the analysis of the instrument that has been done found that the students experience the concept of ionic bonding in the compound NaCl. Students experience misconceptions why NaCl is an ionic compound. In addition, misconceptions are also found about the physical properties of the associated NaCl compounds, ie students believe that NaCl is a compound with a brittle bond and no breaking of bonds in NaCl solution and NaCl has electrolyte properties in solid phase.

Identifikasi tujuan utama dari studi ini adalah untuk menganalisis keterampilan murid dalam berpikir secara kritis menggunakan strategi pembelajaran Problem Based Instruction (PBI) pada materi asam-basa. Studi ini dilakukan pada murid kelas XII MIAdi MA Nahdlatul Ulama Kediri selama tahun ajaran 2021/2022. Studi ini mengadopsi desain one-shot case study yang bersifat deskriptif. Studi ini melibatkan 25 murid yang dipilih secara purposive sebagai sampel. Untuk memperkuat data yang diperoleh, peneliti menggunakan berbagai instrumen seperti tes, lembar observasi, dan wawancara. Temuan dari studi ini menunjukkan bahwa keterampilan murid dalam berpikir secara kritis yang mendapat pembelajaran melalui strategi pembelajaran PBI menunjukkan persentase yang bervariasi pada kelima sub-indikator berpikir kritis. Sub-indikator yang memiliki persentase tertinggi adalah bertanya dan menjawab pertanyaan menantang dengan persentase 86,76% dan berada pada level yang sangat baik. Sub-indikator terkait penarikan kesimpulan dan penilaian hasil memiliki skor 83,83% dengan level sangat baik. Di sisi lain, sub-indikator menilai kehandalan narasumber memiliki skor 72,79%. Sub indikator yang berfokus pada identifikasi asumsi memiliki peringkat baik dengan skor 70,59%. Namun, sub-indikator untuk mengambil keputusan dari suatu tindakan memiliki persentase terendah sebesar 68,38%, menunjukkan peringkat cukup. Berdasarkan temuan tersebut dapat disimpulkan bahwa kemampuan berpikir kritis murid pada pembelajaran asam basa memiliki skor rata-rata sebesar 76,67% yang termasuk dalam level baik.
