Abstract

A study concerning the application of multi-intelligence teaching materials based animation to improve student achievement and student motivation in Chemistry Tadris IAIN Walisongo Semarang on the material structure of the metal packing have been observed. Research using cluster random sampling technique. The samples were divided into experimental class (a class that uses animation-based learning media) and control classes (classes that do not use animation-based learning media). Data analysis showed that there were significant differences between the experimental class and the control class. On the one hand the test calculations obtained t count less than t table with dk = 20 with  = 5%, then we can conclude that Ha is accepted, which means that the average student learning outcomes using media-based learning animation (the experimental group) was better than average of chemistry student learning outcomes that do not use the animation (the control group). As well as in the assessment of the affective aspects. Students who get the lesson with animated media proved to have the learning motivation better than students who do not use animation media. Therefore it can be concluded that the animationbased learning media is effective to improve student achievement and student learning motivation.Keywords: Multi-intelligence Animation-based

Pembelajaran IPA berkaitan erat dengan cara mencari tahu (inkui- ri) tentang alam semesta secara sistematis, sehingga IPA bukan hanya penguasaan pengetahuan berupa fakta, konsep atau prinsip saja, tetapi merupakan suatu proses penemuan. Hal tersebut diperoleh melalui keg- iatan praktikum. Namun, pelaksanaannya di lapangan memiliki beberapa kelemahan antara lain rendahnya pengetahuan guru tentang peralatan kimia dan fungsinya. Hasil penelitian ini menunjukkan calon guru kimia tidak dapat men- gidentifikasi peralatan  laboratorium  dan  mengetahui  fungsinya  secara tepat. Kesalahan mahasiswa dapat diidentifikasi menjadi 5 kategori. Per- tama, sebagian mahasiswa mengetahui nama dan fungsinya namun tidak mengetahui gambar alat (tidak mengetahui wujudnya). Kedua, mengeta- hui nama tetapi tidak mengetahui fungsi dan gambar alat. Ketiga, tidak dapat menyebutkan nama dengan benar tetapi mengetahui fungsi dan gambar alat. Keempat, mengetahui nama dan gambar tetapi tidak menge- tahui fungsinya. Dan yang kelima, tidak mengetahui nama, fungsi maupun gambar alat. Pengetahuan mahasiswa yang kurang dapat dipengaruhi oleh jumlah peralatan dan bahan masih belum mancukupi, keterbatasan waktu praktikum dan perlunya proses pendampingan dari dosen pengam- pu praktikum.

Abstract

Abstrak ___________________________________________________________________ Penelitian didasari dengan belum dikaitkannya budaya batik (budaya khas Pekalongan) sebagai sumber belajar. Tujuan dari penelitian ini yaitu untuk menghasilkan modul pembelajaran kimia berorientasi etnosains batik pada materi larutan elektrolit dan non-elektrolit.  Komposisi modul pembelajarannya disesuaikan pada karakteristik etnosains sehingga dihasilkan modul pembelajaran yang berkualitas. Subjek dari penelitian ini adalah peserta didik kelas X M.A. Salafiyah Simbang kulon Pekalongan. Penelitian menggunakan metode penelitian Research and Development. Hasil uji kelayakan modul pembelajaran kimia tahap I untuk keseluruhan nilai pakar sebesar 82.67% dengan kategori cukup valid. Hasil rata-rata keseluruhan nilai pakar pada validasi tahap II meningkat, yaitu sebesar 90% dan dinyatakan sangat valid. Modul pembelajaran kimia berorientasi etnosains mampu meningkatkan hasil belajar peserta didik dengan nilai n-gain 0.5 yaitu berada pada tingkat pencapaian sedang. Hasil ini menunjukkan bahwa modul yang dikembangkan efektif digunakan dalam pembelajaran.   Abstract ___________________________________________________________________ The study is based on the culture of batik (the particular culture of Pekalongan) has not been included as a learning resource. The purpose of this study is to produce batik ethnoscience-oriented of  chemical learning modules on material electrolyte and non-electrolyte solution. The composition of customized learning modules on the characteristics ethnoscience to produce quality learning modules. The subject of this research is the students of class X M.A. Salafiyah Simbangkulon Pekalongan. The study uses research methods Research and Development. The results of the feasibility test of chemistry learning modules of Phase I for overall value amounted to 82.67% of experts with fair valid category. The average yield of the overall value of experts in the validation phase II increased by 90% and declared very valid. Chemistry learning module that oriented ethnoscience could improve the students achievement with the score 0.5 n-gain that existed in the medium achievement. This result showed that the modules which developed are effective used in the learning.

Abstract

The Research about Synthesis and Characterization of SiO2 have been worked. We have synthesized Silica from “petung”bamboo leaf ash as SiO2 source. This step used sol gel methode. SiO2 were characterized by Fourier Transform Infra Red (FTIR) to investigated the stucture andX-Ray Diffaction to know about structure and crystallinity. FTIR spectra show peak at 617,22 cm-1 area that spesific for Si-H bond, peak at 786,96 cm-1and 1095,57 cm-1 area specific for Si-O-Si bonds. Difractogram of SiO2 show that there are peak at 2θ 21,99; 31,67 and 38,88 were specific for SiO2 that calcinated at 800oC, while for SiO2 that calcinated at 400oC there were no peak at 2θ 31,67 dan 38,88. That peaks not shown may be because low crystallinity of SiO2 that calcinated at 400oC. Calcination temperature greatly affects the crystallinity of SiO2.©2017 JNSMR UIN Walisongo.

Abstract

Assistance to the community is provided in order to provide education using fast, good and correct learning methods. In addition to literacy education of the Quran, coastal communities who work as fish seekers on average also need to be equipped with skills (life skill). Through education and training, coastal communities will have two advantages at once, first able to study the Quran quickly, rightly and correctly, and both gain knowledge about fish waste processing. Devotion is done also provide life skill education (life skills) such as processing pellets / feed from fish waste. Supply provided is not limited to the training course but also helps in the management of production permits and feasibility of processing the pellet, and find opportunities in marketing the processed products.

Abstract

Galvanization is a metal coating process that is widely used in industry. The effects of this metal coating process are not entirely beneficial to society. The issue of pollution generated by the metal coating activity becomes very important. The objective of this research is to reduce Fe metal content from solid waste steel using electrolysis process with variation of pH of electrolyte solution and voltage. This research uses experimental method with test of metal content composition using X-Ray Flouresence, and Fe metal reduction using electrolysis process. This research activity used stainless steel plate as cathode and solid steel waste chunk as anode. Variations of pH of FeSO4.7H2O electrolyte solution used during electrolysis process are pH = 2, pH = 2.5, pH = 3, pH = 3.5 and pH = 4. Variation of electric voltage used is 3 volts, 6 volts, 9 volts and 12 volts. The result of purity level analysis of the initial Fe metal at anode was 84,48 %, while after electrolysis process there was an increase of metal purity attached to the cathode of 96,58 %. The result showed that the effect of pH variation of the electrolyte solution on the mass produced in the electrolysis process in the A1, A2, A3, A4 and A5 samples was 0,09; 0,07; 0,02; 0,02; and 0,02 g. The greater the concentration of H+ of the electrolyte solution the more mass produced. In variable voltage of electricity on samples A11, A21, and A31 mass produced that is equal to 0,14; 0,13; and 0,10 g. While the mass of A41 sample did not increase in the cathode produced during the electrolysis process. The greater the voltage used in the electrolysis process the greater the mass produced.
