Pembelajaran Sains Berbasis Homeschooling (Sekolah Rumah) pada Homeschooling Primagama (HSPG) Yogyakarta
No full textPenelitian ini bertujuan untuk mendeskripsikan alasan-alasan yang melandasi terlaksananya sistem belajar secara homeschooling di lembaga HSPG, dan mengetahui proses pembelajaran sains yang dijalankan dan implikasinya
terhadap hasil belajar siswa.
Jenis penelitian ini adalah penelitian kualitatif dengan metode studi kasus bertipe deskriptif. Penelitian ini dilaksanakan pada Lembaga Homeschooling Primagama (HSPG) yang ada di kota Yogyakarta. Subyek penelitian adalah para
pelaku homeschooling di lembaga HSPG, yaitu siswa, para tentor, terutama tentor sains, dan penyelenggara HSPG, serta orang tua siswa. Pengumpulan data dilakukan dengan menggunakan teknik angket, wawancara, observasi, dan
dokumentasi. Data dari angket dianalisis dan diolah, selanjutnya dikonfirmasikan dengan hasil wawancara, observasi, dan data dokumentasi yang diperoleh.
Hasil penelitian ini mengungkapkan bahwa penyelenggaraan sistem belajar secara homeschooling di HSPG dilandasi oleh kenginan manajemen lembaga untuk melakukan inovasi layanan pendidikan informal secara homeschooling bagi masyarakat, sedangkan bagi siswa dan orang tua siswa dilandasi oleh alasan dan pertimbangan, yaitu: kasus bullying, anak anti sekolah, beban psikologis anak, kesehatan anak, ketidaksinkronan anak dengan sistem sekolah, masalah pribadi anak, kenyamanan belajar, layanan pendidikan
berkualitas, alasan ideologis, mobilitas orang tua, kebutuhan khusus anak, dan upaya melanjutkan pendidikan anak yang terputus. Selanjutnya diperoleh pula bahwa perilaku awal siswa dalam hal budaya belajar tampak belum optimal sebelum mengikuti sistem homeschooling di HSPG, tetapi dalam hal hubungan sosial sudah cukup baik. Sementara itu, proses pembelajaran sains secara homeschooling di HSPG dapat berlangsung secara normal menggunakan kurikulum yang berlaku secara Nasional yang diimplementasikan menurut sistem homeschooling. Hambatan pembelajaran dari aspek fasilitas dapat ditunjang oleh
adanya sekolah payung dan lembaga lain yang membantu. Di samping itu, proses pembelajaran sains oleh para tentor sains di HSPG, masih didominasi oleh pendekatan pembelajaran secara konvensional, terutama untuk kelas puncak, tetapi pada kelas non puncak menyesuaikan dengan tuntutan materi sains yang diajarkan. Sistem homeschooling di HSPG ternyata mampu menghasilkan kualitas hasil belajar siswa ke arah yang lebih baik bila ditinjau dari aspek kognitif, afektif, maupun psikomotorik. Dengan sistem ini, anak maupun orang tua tidak merasa asing dan risih dengan lingkungannya, bahkan cukup optimis dan percaya diri akan prospek keberhasilan sistem ini
Artikel ADM Muhamad Rido
No full textStudents are a very important element in educational and teaching activities in schools. Educational institutions are established for the benefit of students. Therefore it needs to get enough attention from the implementation of education in order to achieve the objectives of national education as a whole.Therefore, as a prospective educator later, in order to be able to administer for students so that the learning process runs well it is necessary to understand about the administration of students / students. Therefore, the author tries to make a paper that discusses the administration of students
Imobilisasi Asam Humat Pada Kitin Dan Aplikasinya Sebagai Adsorben Cr(III)
No full textImmobilization of humic acid on chitin has been conducted and applied to the adsorption of Cr(III). The humic acid was isolated using NaOH 0.1 M, while chitin was isolated by deproteination of crab shells by using NaOH 3.5 % (w/v) and followed by demineralization using HCl 1 M. Chitin obtained from ambient-temperature-dried crab shell is named as chitin I, and crab shell washed by HOCl solution and followed by drying at ambient temperature is named chitin II. The total acidity of the humic acid was 230.95 cmol/kg, and it was distributed into the acidity of COOH 168.75 cmol/kg, and phenolic-OH 62.20 cmol/kg. Adsorbent A with chitin I as the main material and adsorbent B with chitin II as the main material, resulted the adsorbed humic acid of 9.25 and 1.68% (w/w), respectively. Adsorption of Cr(III) was maximum at pH 5, with rate of constants orde of chitin II>adsorbent B>adsorbent A>chitin I, i.e. 0.3509; ; 0.2488; 0.1553; 0.0568 minute-1, respectively. The capacity of adsorption was in the orde of chitin I>adsorbent B>chitin II>adsorbent A, i.e. 944.77; 912.53; 895.37; 893.81 mg/g, respectively. The energy of adsorption of Cr(III) of chitin II>chitin I>adsorbent A>adsorbent B, i.e. 22.932; 20,945; 20.312; 19.615 kJ/mol, respectively
Design maintenance for lighthouse / Muhamad Rashid Ab Aziz
No full textAs lighthouses have become less essential to navigation, many of their historic structures have faced demolition or neglect. So, this final project will enlighten with more detail regarding the maintenance works for lighthouse. This research of the study will involves marine department of Malaysia as a government organization that responsible to manage lighthouses. The aim of this final project is to investigate the implementation of marine department to maintain the lighthouse and suggest the best design maintenance for lighthouse. To support this research, four lighthouses have been taken as case studies. The data gathered from observation, condition survey and interview conducted at the site. It is hoped that the overall findings of the study will be beneficial for further research that can be developed in this particular area. Besides that, the analysis is made to achieve the objective of this study. Conclusion and recommendation also made in the last chapter to achieve the objective of the study. From this study, the author hopes that it would give clear awareness to us why the important of lighthouse to be maintain
THE UTILIZATION OF CHITOSAN THIOUREA FOR Cd(II) PRECONCENTRATION BY THE SOLID PHASE EXTRACTION (SPE) TECHNIQUE
No full textChitosan thiourea has been synthesized from crab shell starting material and the product of synthesis was then utilizing for Cd(II) metal preconcentration in the sea water medium. Synthesis process is done through the interaction between chitosan solution with thiourea solution, and was then characterized by FTIR spectrophotometer and XRD diffractometer. The preconcentration of Cd(II) metal conducted by using adsorption-desorption process with the flow injection system of Cd(II) metal solution in the SPE technique. The preconcentration process of Cd(II) metal also involved the influence of acidity, flow rates, and salt concentration to obtain an optimum preconcentration level.-
As a result, this study revealed that the successfully of chitosan thiourea synthesis process well marked by interaction between chitosan active sites (-NH2) and thiourea compound, which showed by the changes of chitosan FTIR spectra at the 1577.7 cm&mac
SYNTHESIS OF THIOUREA DERIVATIVE OF CHITOSAN AND ITS APPLICATION IN CADMIUM (II) AND NICKEL (II) ADSORPTION
No full textThe synthesis of new thiourea derivative of chitosan and its characterization by Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (X-RD) is described. The thiourea derivative of chitosan, were prepared by adding an acetic acid solution of chitosan into aqueous solution of thiourea. An insoluble thiourea chitosan were obtained after an exess adition of NaOH. The adsorption capacity of the product for cadmium (II) and nickel (II) were tested at several metal concentrations of different values of pH. A Langmuir model for adsorption isotherm is applied for comparing the adsorption properties of the two metals investigated.</p
