Abstract

ABSTRAKPenelitian ini bertujuan untuk mendeskripsikan dan menjelaskan profil model mental siswa, serta menganalisis faktor-faktor yang memengaruhi terbentuknya model mental alternatif siswa kelas X MIA di SMA Laboratorium Undiksha Singaraja pada materi ikatan ion dan ikatan kovalen. Penelitian ini menggunakan pendekatan mix methods, jenis sekuensial. Pengumpulan data dilakukan dengan observasi, tes model mental, dan wawancara. Instrumen yang digunakan adalah tes diagnostik pilihan ganda dua tingkat dan wawancara dengan pertanyaan menyelidik. Hasil penelitian menunjukkan persentase siswa yang memiliki model mental ilmiah tentang ikatan ion dan kovalen sebanyak 53,33% model mental alternatif sebanyak 38,89%, dan 7,78% tidak memberikan tanggapan. Faktor-faktor yang memengaruhi terbentuknya model mental alternatif meliputi kekurangan informasi, kekeliruan penalaran, dan buku teks kimia yang digunakan siswa sebagai sarana belajar. Sehubungan dengan temuan tersebut, guru kimia di SMA perlu menerapkan strategi pembelajaran yang tepat untuk mengajarkan ketiga level kimia secara utuh.Kata Kunci: ikatan ion, ikatan kovalen, model mental, model mental alternatifABSTRACTThis research was aimed to describe and explain the profile of mental model student’s, and analyze the factors that influence the formation of alternative mental models of class X MIA students at SMA Laboratorium Undiksha Singaraja about ionic bonding and covalent bonds material. This research is a mix method approaches in research, a sequential type. Data collection is done by observation, mental model tests, and interviews. The instrument used in this study was a diagnostic test two tier and interview with probing questions.

Abstract

Seiring dengan perkembangan teknologi yang makin pesat di negara kita, jumlah industri yang ada di Indonesia semakin banyak. Salah satunya adalah industri electroplating. Industri ini berkembang di bidang pelapisan. Selain menghasilkan produk yang berguna, industri ini juga menghasilkan limbah. Limbah yang dihasilkan banyak mengadung logam berat. Salah satunya adalah logam krom. Jika logam krom dalam limbah sedikit mendapatkan perlakuan, hal ini dapat menyebabkan polusi di lingkungan. Meskipun limbah ini ada dalam jumlah kecil, tetapi dengan kondisi krom yang stabil dan jika terakumulasi dalam tubuh pada akhirnya dapat memicu sel-sel kanker (karsinogenik) yang bisa berbahaya bagi kesehatan. Pada penelitian ini dilakukan adsorpsi ion Cr3+ pada limbah electroplating dengan menggunakan bio-charcoal bamboo. Penelitian ini bertujuan mengetahui efektivitas bio-charcoal bambu untuk menyerap logam berat (Cr) yang terkandung di limbah electroplating dan karakteristik serapan ion Cr3+ pada limbah electroplating dengan menggunakan bio-charcoal bambu. Pengukuran konsentrasi ion Cr3+ sebelum dan sesudah mendapatkan perlakuan dilakukan dengan alat instrument yaitu AAS pada panjang gelombang 357,74 nm. Hasil penelitian menunjukkan bahwa efektivitas bio-charcoal bamboo untuk menyerap ion Cr3+ yang ada di limbah electroplating adalah dengan massa optimum 2 gram, sedangkan waktu kontaknya adalah 8 jam dan adsorpsi bio-charcoal mengikuti pola isotherm adsorpsi Langmuir dengan daya adsorpsi maksimum sebesar 0.190 g/g.Kata Kunci : Adsorpsi, bio-charcoal bamboo, electroplating Along with the fast development of technology in our country, the number of industries in Indonesia is growing. One of them is electroplating industry. The industry is growing in the field of coating. Besides producing useful products, this industry also produces waste. The waste produced that contain many heavy metals. One of them is chrom. If chrom metal wastes less to get the treatment, it can influence pollution in environment. Although this waste present in small amount, but the condition of chrom is stable and if it accumulates in the body can eventually lead to cancer cells (carcinogenic) that can be harmful to health. In this research, the adsorption of Cr3+ ions in electroplating waste was done by using bio-charcoal bamboo. This research aims to know the effectiveness of bio-charcoal from bamboo to reduce/adsorb the heavy metal (Cr) that content in the electroplating waste and the characteristic of adsorption Cr in electroplating waste by bio-charcoal bamboo. The measurement of Cr3+ ion concentration before and after getting treatment was done by AAS at a wavelength of 357.74 nm. The results showed that the effectiveness of bio-charcoal bamboo to absorb the of Cr ions in electroplating waste is to optimum mass of 2 grams, while the contact time is 8 hours and bio-charcoal adsorption followed Langmuir adsorption isotherm pattern with maximum of adsorption capacity was 0.190 g/g.keyword : Adsorption, bio-charcoal bamboo, electroplating
