Abstract

Pemakaian plastik dalam kehidupan sehari-hari sebagai pengemas terus mengalami peningkatan menyebabkan limbah plastik semakin bertambah dari hari ke hari. Sampah plastik berasal dari bahan baku minyak bumi sulit terurai oleh mikroba di dalam tanah. Salah satu cara untuk mengurangi penggunaan plastic non-degradable yaitu dengan memproduksi plastik dari bahan-bahan organik yang mengandung pati didalamnya. Penelitian ini dilakukan untuk mengkaji pengaruh banyaknya penambahan gliserol dan CaCO3 pada tepung biji durian dalam pembuatan plastik biodegradable. Plastik biodegradable dibuat dengan melarutkan tepung biji durian dengan aquades ditambah dengan gliserol dan CaCO3. Selanjutnya variasi rasio CaCO3 (0 gram, 0,5 gram, 1 gram, dan 1,5 gram) dengan gliserol (25%, 35%, 45%, dan 55% dari berat tepung biji durian). Karakteristik biodegradable ditandai dengan adanya uji biodegradasi, uji kuat tarik dan elongasi. Hasil karakterisasi plastik biodegradable yang memiliki kinerja optimal diperoleh dari plastik biodegradable dengan kuat tarik 0,71 Mpa, persen elongasi 16,3%, dan waktu degradasi 14 hari.

Abstract

Hasil penelitian membuktikan bahwa arang aktif dapat dibuat dari bahan organik maupun anorganik yang mengandung kadar karbon tinggi. Dari sejumlah penelitian yang telah dilakukan, penelitian karbon aktif biasanya dari limbah kayu, tempurung kelapa, cangkang buah karet dan sebagainya. Padahal masih banyak yang dapat dimanfaatkan untuk pembuatan karbon aktif, salah satunya adalah kulit kayu gelam yang tumbuh di daerah Tanjung Api-Api, Sumatera Selatan. Pembuatan karbon aktif dilakukan dengan variabel suhu karbonisasi (250oC; 350oC; dan 450oC) dan jenis zat aktivator (CaCl2 5%; NaOH 5%; dan H3PO4 5%). Adapun parameter analisa karbon aktif yang diuji adalah kadar air, kadar volatile matter, kadar abu, dan daya serap iodium. Analisa kandungan kimia kulit kayu gelam dilakukan menggunakan metode Chesson?Datta yang meliputi kadar air, kadar abu, hemiselulosa, selulosa, dan lignin. Karbon aktif terbaik dengan daya serap iodium sebesar 1007,8242 mg/g dihasilkan dari suhu karbonisasi 350oC, dengan menggunakan zat aktivator NaOH, dan lama aktivasi 24 jam. Analisa kandungan kimia kulit kayu gelam yang diperoleh, yaitu kadar air sebesar 5,72%; kadar abu 1,33%; hemiselulosa 27,42%; selulosa 47,00%; dan lignin 18,28%.

Abstract

Reaksi hidrogenasi syngas yang berasal dari gas alam, batu bara dan biomassa telah lama digunakan untuk menghasilkan hidrokarbon rantai panjang dan alkohol. Hidrokarbon rantai panjang dapat diproses lebih lanjut menjadi synthetic fuel (bahan bakar sintetik) sebagai pengganti minyak bumi. Reaksi hidrogenasi tidak terlepas dari peran katalis. Salah satu katalis yang paling efektif untuk reaksi ini adalah ruthenium (Ru). Penelitian ini mempelajari Pengaruh ukuran partikelruthenium (Ru) dalam katalis ruthenium-alumina (Ru/Al2O3) yang digunakan dalam reaksi hidrogenasi karbon monoksida. Gas karbon monoksida (CO) dan hidrogen (H2) digunakan sebagai reaktan dengan perbandingan 2:1.Reaksi hidrogenasi karbon monoksida dilakukan dengan menggunakan reaktor fixed-bed yang terbuat dari pyrex glass. Tiga macam variasi jumlah ruthenium yaitu 7wt%, 10wt% dan 12wt% digunakan dalam katalis Ru/Al2O3. Metode pembuatan katalis menggunakan metode impregnasi dan reaksi dilakukan dengan rentang temperatur dari 160 ?C sampai 260 ?C pada tekanan atmosferik. Pengambilan sample produk dilakukan setiap 30 menit dan produk dianalisa dengan menggunakan gas-chromatograph (GC). Hasil reaksi menunjukkan bahwa ruthenium dengan berat 12wt% menghasilkan konversi CO yang paling tinggi dibandingkan dengan katalis jumlah 7wt% dan 10wt% ruthenium.
