Abstract

Pembelajaran dibidang Kimia seringkali dianggap sulit bagi pelajar maupun mahasiswa terutama untuk bidang perhitungan kimia dan deskripsi objek yang dipelajari di kimia yang cenderung abstrak, kendala ini mesti dicari solusinya agar bidang kimia yang punya peranan penting di kehidupan dapat dipelajari dengan baik oleh pelajar ataupun mahasiswa, sehingga Sumber Daya Manusia (SDM) yang memahami kimia akan dapat termanfaatkan dengan baik demi kemajuan bangsa. Penelitian ini bertujuan untuk mengetahui pengaruh dan efektivitas Chess of Chemistry (COC) sebagai Media Pembelajaran terhadap pembelajaran siswa pada pokok bahasan Stoikiometri khususnya dan perhitungan kimia pada umumnya, penelitian ini berjenis eksperimen (Experiment Research) yang melibatkan 2 kelas yang mengambil perwakilan dari kelas-kelas IPA yang dipilih berdasarkan homogenitas sebagai sampel. Populasi dari penelitian ini adalah pelajar bidang IPA SMAN 8 Kota Bengkulu, pengujian efektivitas dari COC ini dilakukan dengan membandingkan rata-rata nilai dan kecepatan berpikir menggunakan tes yang singkat(dalam rentang waktu yang sempit), antara kelas yang menggunakan Chess of Chemistry (COC) dalam pembelajaran dan yang tidak, dengan membandingkan nilai rata-rata tes, waktu dan nilai rata-rata tes sebelumnya serta membandingkan nilai rata-rata kelas yang menggunakan COC dan kelas yang menggunakan metode konvensional, kesimpulan efektivitas positif diambil, jika nilai rata-rata kelas dengan metode menggunakan Chess of Chemistry (COC) > dari kelas yang menggunakan metode tanpa media Chess of Chemistry (COC). Kata kunci: Pembelajaran, Efektivitas, Media Pembelajaran, Stoikiometri, Perhitungan Kimia, Chess of Chemistry (COC) atau Catur Kimia.

Abstract

One of the heavy metals contained in the textile industry wastewater is chromium (Cr). Chromium hexavalent ions (Cr6+) are highly toxic and its accumulation in the human body will cause various negative impacts. This study aimed to determine the characteristics of silica synthesized by the sol-gel method to gain homogeneity and high purity. Synthesized silica was calcined at 700°C for 4 hours and its performance to adsorb Cr(VI) ions  in textile wastewater was investigated. The presence of -OH group from silanol (–Si-OH) was appeared at wavenumber 3367.70 cm-1, meanwhile siloxane functional groups were recorded at 1056.99 cm-1 and 784.38 cm-1 due to the O-Si-O asymmetric stretching and Si-O bending vibration. Optimum conditions of silica to adsorb Cr(VI) ions took place at pH 2 and contact time of 90 minutes by adsorption efficiency of 75,65% and followed the Freundlich isotherm.

Abstract

This paper aims to explain and describe the implementation of the concept of sustainable water management applied at UIN Raden Fatah Palembang, as part of the implementation of the green campus idea. UIN Raden Fatah's participation in the UI GreenMetric program has been started since 2019 and will be active in 2020. Water management is an important thing at UIN Raden Fatah Palembang because of the condition of the campus itself which is in a water reservoir and swamp area. The campus is divided into two locations, namely Campus A in the Jalan Jenderal Sudirman area and Campus B in the Jakabaring area, Palembang. Campus B is a new campus that will only start operating in 2021, therefore, water management arrangements are very important. The management of water resources is carried out with the Wash program which consists of revitalizing clean water infrastructure, metering clean water supply, water reuse program, improving surface water quality, as well as construction of drainage and canalization. In practice, higher education leaders issue policies that involve all the academic community, ranging from education staff, educators, to students. Keyword: water, green campus, sustainable, swamp
