PENGEMBANGAN BAHAN AJAR ANALISIS KATION GOLONAGN IV DAN V DENGAN MODEL PEMBELAJARAN KOOPERATIF STAD UNTUK SMK PROGRAM KEAHLIAN KIMIA ANALISIS

ABSTRAK Susanti, Laily Yunita. 2011. Pengembangan Bahan Ajar pada Materi Analisis Kation Golongan IV dan V dengan Model Pembelajaran Kooperatif STAD untuk SMK Program Keahlian Kimia Analisis. Skripsi, Jurusan Kimia FMIPA Universitas Negeri Malang. Pembimbing: (1) Drs. Darsono Sigit, M. Pd., (2) Dra. Hayuni Retno, M. Si. Kata kunci: bahan ajar, analisis kation, model pembelajaran kooperatif STAD. Bahan ajar merupakan salah satu faktor yang menentukan keberhasilan pembelajaran di berbagai tingkat pendidikan baik SMP/ MTs dan SMA/ MA/ SMK. Melalui bahan ajar guru dan siswa akan lebih mudah dalam menjalankan proses belajar mengajar. Depdiknas (2007) menyebutkan bahwa salah satu problematika pembelajaran di SMK adalah belum tercukupinya bahan ajar yang dapat memenuhi standar kompetensi lulusan baik secara kuantitatif, kualitatif, dan relevansinya. Untuk itu peneliti mengembangkan bahan ajar untuk materi Analisis Kation Golongan IV dan V berdasarkan SK dan KD pada silabus KTSP SMK. Tujuan dari penelitian pengembangan adalah untuk mengetahui hasil pengembangan bahan ajar kimia pada materi Analisis Kation Golongan IV dan V yang dikembangkan dengan model pembelajaran kooperatif STAD untuk SMK Program Keahlian Kimia Analisis dan mengetahui kelayakan bahan ajar yang telah dikembangkan ditinjau dari hasil validasi isi dan uji terbatas. Model pengembangan bahan ajar mengadaptasi desain Dick and Carey yang terdiri dari 10 langkah penelitian. Namun karena keterbatasan waktu dan biaya penelitian hanya dilakukan hingga tahap ke-9. Desain validasi bahan ajar terdiri dari validasi soal uji kompetensi dan validasi isi produk. Validasi soal uji kompetensi dilakukan dengan mengujicobakan soal ke siswa SMK Program Keahlian Kimia Analisis kemudian dianalisis validitas, reliabilitas, tingkat kesukaran, dan daya bedanya. Validasi isi bahan ajar yang dilengkapi dengan RPP dilakukan oleh 5 validator yaitu 1 dosen kimia dan 4 guru kimia SMK. Instrumen pengumpulan data berupa soal uji kompetensi dan angket. Data yang diperoleh berupa data kuantitatif dan data kualitatif. Berdasarkan analisa terhadap data kuantitatif dan data kualitatif yang diperoleh dapat diketahui kelayakan bahan ajar yang telah dikembangkan. Setelah dilakukan validasi bahan ajar kemudian dilakukan uji terbatas kepada 9 siswa SMK. Hasil dari pengembangan adalah bahan ajar Analisis Kation Golongan IV dan V yang dilengkapi dengan Rencana Pelaksanaan Pembelajaran (RPP). Dari hasil validasi bahan ajar diperoleh nilai rata-rata 3,05 dengan kriteria valid/baik/layak sedangkan dari hasil validasi RPP diperoleh nilai rata-rata 2,98 dengan kriteria valid/baik/layak. Berdasarkan hasil uji terbatas, diperoleh nilai nilai rata-rata 3,36 dengan kriteria sangat valid/ sangat baik/ sangat layak untuk bahan ajar. Oleh karena itu, dapat disimpulkan bahwa bahan ajar Analisis KationGolongan IV dan V yang dilengkapi dengan RPP sudah layak dan baik untuk divalidasi secara empirik (evaluasi sumatif) di lapangan. ABSTRACT Susanti, Laily Yunita. 2011. Developing of Teaching Material on Analysis of Cation IV and V Group by Using STAD Cooperative Learning for Vocational High School Chemistry Analysis Skill Program. Thesis, Chemistry Department, Mathematic and Scientific Faculty, State University of Malang. Supervisor lecturer: (1) Drs. Darsono Sigit, M. Pd., (2) Dra. Hayuni Retno, M. Si. Key words: teaching material, analysis of cation, and STAD cooperative learning. Teaching material is one of several factors which determine the success of learning in any level of education either Junior High School or Senior/Vocational High School. By using teaching material both teacher and students will easily held the learning process. Depdiknas (2007) stated that problem of learning in Vocational High School was the teaching materials which conform standard of competence for graduates haven’t been satisfied yet. Because of the reason, reseacher tried to develop teaching material for Analysis of Cation IV and V Group based on standard of competence (SK) and basic competence (KD) on KTSP sillaby of Vocational High School. The goals of this research were to describe developing result of teaching material and lesson plan on Analysis of Cation IV and V Group that have been developed by using STAD cooperative learning model for Vocational High School Chemistry Analysis Skill Program and to describe suitability of teaching material and lesson plan based on content validation and limited field test. Developing model of teaching material adapted Dick and Carey’s design which consisted of 10 steps of research. However, it was being directed till 9th step of research only because of time and fee limits. Validation design of teaching material was validation of evaluation test and content validation of product. Validation of evaluation test have been done by trying the test to Vocational High School students then the result have been analyzed using validity, reliability, difficulty level, and deviation. Content validation of teaching material have been done by 5 validators (1 chemistry lecturer and 4 chemistry teacher of Vocational High School). Instruments being used was eveluation test and questionnaire. Datas which have been gotten was qualitative and quantitative datas. Based on analysis of datas, the suitabiliy of teaching material can be identified. After doing content validation researcher also held limited field test to 9 students of Vocational High School. Results of research and development were teaching material and lesson plan on Analysis of Cation IV and V Group. Based on content validation of teaching material have been gotten average mark 3,05 with valid/good/suitable criteria while based on content validation of lesson plan have been gotten average mark 2,98 with valid/good/suitable criteria. Based on limited field test have been gotten average mark 3,36 with very valid/ very good/ very suitable criteria for teaching material. Therefore, researcher concluded that teaching material and lesson plan on Analysis of Cation Group IV and V which have been developed by STAD cooperative learning model was valid/good/suitable and able to be validated empirically (summative evaluation) in Vocational High School students
