Namun dalam tulisan ini, yang dimaksudkan sebagai kimia bahan alam adalah konstituen “organik bahan alam” yang berasal dari sumberdaya hayati, lebih khusus metabolit sekunder yang akhir-akhir ini semakin banyak mendapat perhatian para peneliti kimia dan semakin diandalkan sebagai penopang perkembangan industri maju diberbagai negara. Selogan Back to natural semakin meluas dan menjadi alternatif dalam penyelesaian berbagai masalah besar yang dihadapi masyarakat global saat ini. Terutama dalam pemenuhan bahan sandang, pangan serta bahan obat-obatan yang semakin meningkat tajam. Meski muncul sebagai alternatif baru, kiranya selogan tersebut dimaknai sebagai kebersesamaan dengan alam, tidak menjadikan alam semata-mata sebagai objek yang terus dieksploitasi tanpa terkendali. “Beri yang terbaik untuk alam, karenanya kita akan mendapatkan terbaik pula darinya.” Selama ini, sumber devisa pembangunan nasional bertumpu pada bahan alam berupa hasil-hasil tambang. Eksploitasi komponen kimia alam tak-terbaharukan yang terjadi selama ini semakin memperihatinkan, sumberdaya alam berupa material tambang batu bara, emas, nikel, gas dan minyak bumi semakin menipis, situasi ini kian menyeret kita pada kebangkrutan. Karenanya diperlukan reorientasi pengelolaan dan pemanfaatan sumberdaya alam yang lebih bijak dan berkelanjutan. Sebagai negara yang memiliki sumberdaya alam hayati melimpah bangsa Indonesia seharusnya memprioritaskan pengembangan IPTEKS yang berorientasi pada sumber daya alam hayati.

nmb a2200000Iu 4500 "130204 2013 eng " dc Inovasi Pendidikan Tinggi Kimia Indonesia: Suatu Konsep Pemikiran Paradigma Baru Rijai, Laode Pengelompokan bidang ilmu/rumpun ilmu di Indonesia untuk kebutuhan pengelolaan kelembagaan didasarkan pada peran atau fungsi keilmuan tersebut pada aplikasi dan bukan pada kesamaan atau kemiripian materi kajian keilmuan.Hal ini telah mengakibatkan pemborosan sumberdaya terutama fasilitas laboratorium dan sumberdaya manusia khususnya staf pengajar. Laboratorium merupakan sumber belajar suatu Program Studi akan memiliki fasilitas dan desain yang sama dengan laboratorium Program Studi lainnya yang memiliki kesamaan atau kemiripan materi kajian.Hal ini terjadi pada keilmuan Kimia yaitu tergabung dalam Fakultas Matametika dan Ilmu Pengetahuan Alam untuk Program Studi Kimia, dan Program Pendidikan Kimia tergabung dalam Fakultas Keguruan dan Ilmu Pendidikan, serta Kimia Teknik tergabung dalam fakultas teknik atau lembaga tersendiri. Pengelolaan kelembagaan yang demikian itu telah berakibat pada pemborosan sumberdaya yaitu suatu Perguruan Tinggi akan memiliki sarana dan parasarana laboratorium yang sama pada beberapa fakultas, demikian pula untuk tenaga pengajar. Selanjutnya, keilmuan kimia pada Pendidikan Tinggi Kimia Indonesia terus menurun peminatnya dari tahun ke tahun karena keilmuan kimia tetap konsisten sebagai ilmu dasar dan enggan melanjutkan kajian pada terapan langsung terkait kebutuhan mahluk hidup.Dalam filsafat ilmu, ilmu kimia menempati seluruh strata ilmu pengetahuan yaitu mulai dari perihal mendasar hingg aplikatif, namun pada kenyataannya hanya peran sebagai dasar keilmuan untuk aplikatif. Jika kita menelaah lebih detail definisi ilmu kimia yaitu mengkaji materi dan perubahannya, seharusnya tidak terbatas pada materi yang namanya atom, unsur, dan senyawa, akan tetapi seluruh materi di jagat ini melibatkan proses perubahan kimia dan fisika. Karena itu sangatlah mudah merumuskan Program Studi Kajian Kimia yang berorientasi pada terapan langsung yang terkait dengan kebutuhan mahluk hidup.Terapan-terapan kimia secara langsungsaat ini justru muncul bukan dari para ahli kimia tetapi dari para pemanfaat ilmu kimia.Oleh karena itu diperlukan pemikiran baru tentang pengembangan Pendidikan Tinggi Kimia di Indonesia, antara lain membentuk Fakultas Kimia yang mengelola Program Studi-Program Studi berbasis keilmuan kimia dan terus mengembangkan Program Studi Baru tentang Kimia yang terkait secara langsung dengan kebutuhan masyarakat.Pengkajian perihal tersebut dapat dimulai dari pembentukan wadah asosiasi untuk keperluan diskusi para ahli kimia di Indonesia dalam mengembangkan kelembagaan Pendidikan Tinggi Kimia di Indonesia.

nmb a2200000Iu 4500 "160426 2016 eng " dc POLIMER BIODEGRADASI DAN APLIKASINYA Arcana, I Made Meningkatnya produksi polimer/bahan plastik sintetik disebabkan karena bahan plastik dapat digunakan pada berbagai aplikasi, baik bahan plastik untuk bidang kedokteran, farmasi, pertanian, dan bahan pengemas maupun bahan plastik untuk aplikasi material yang lebih maju seperti membran polimer elektrolit. Sampah plastik yang telah digunakan tersebut menjadi masalah yang sangat serius, karena tidak seperti polimer alam, sebagian besar polimer sintetik tidak dapat didegradasi oleh mikroorganisme yang ada di alam. Untuk mengatasi masalah tersebut telah dikembangkan suatu material yang dikenal sebagai polimer yang dapat terbiodegradasi (Biodegradable Polymers). Ada berbagai cara yang digunakan untuk mendapatkan polimer yang dapat terbiodegradasi di alam antara lain melalui biosintesis dan sintesis secara kimia polimer baru yang dapat terbiodegradasi, serta modifikasi polimer non biodegradasi melalui pembentukan poliblend dengan polimer biodegradasi, penambahan aditif pro-oksidan ke dalam polimer, dan modifikasi polimer alam untuk berbagai aplikasi. Dalam kesempatan ini akan disampaikan beberapa polimer biodegradasi yang dapat diperoleh dari sintesis secara kimia, modifikasi polimer non biodegradasi dengan polimer biodegradasi baik melalui pembentukan kopolimernya ataupun poliblendnya, modifikasi melalui penambahan aditif pro-oksidan dalam pembentukan polimer okso-degradasi, serta beberapa aplikasinya baik untuk bahan plastik pengemas maupun untuk material maju (Advanced Materials) terutama sebagai bahan membran polimer elektrolit untuk ap likasi sel bahan bakar dan sel baterai litium. Salah satu membran polimer elektrolit untuk aplikasi baterai litium diperoleh melalui modifikasi polimer alam seperti kitosan. Modifikasi kitosan dilakukan melalui penambahan gugus suksinat ke dalam kitosan menggunakan asam suksinat anhidrida, sedangkan membran polimer elektrolit dibuat dari kitosan suksinat dan garam litium perklorat digunakan sebagai garam ioniknya. Substitusi gugus suksinat pada kitosan dapat meningkatkan hantaran ionik membran dari 2,88 × 10 -6 S.cm -1 untuk kitosan murni, 5,06 x 10 -5 S.cm -1 untuk kitosan- Li5%, dan menjadi 8,04 x10 -2 S.cm -1 untuk kitosan suksinat-Li5%. Sebaliknya adanya gugus suksinat dalam kitosan cenderung menurunkan sifat mekanik dan sifat termal membran.

Cotton fabric is proposed as an alternative material for low cost point of care devices. Cotton fabrics are vastly available, low cost and flexible. Simple wax patterning method was applied to create hydrophilic channels in cotton fabric. Three-dimensional (3-D) colorimetric microfluidic device was made by folding 2-D pattern along certain predefined lines. 3-D devices show better mixing uniformity between reagents and analyte across the detection zones. On-chip colorimetric calibration is also proposed by putting predefined serially diluted samples next to the detection zones. Multiple assays can be integrated within a small surface area by stacking layers of individual assay device separated by a wax-impregnated fabric. Cotton fabric was also used as a platform for conducting Enzyme-Linked Immunosorbent Assay (ELISA). The colorimetric performance is similar to the conventional absorbancebased ELISA, yet with lower cost and shorter time to get results. A second type of device using electrochemical detection principle is also implemented in cotton fabric with three electrode configuration (working, counter and reference electrode), using similar simple and low-cost wax-patterning. In both colorimetric and electrochemical device, comparison with te already popular paper-based device will be discussed. Finally, we present latest results in our lab in which cotton fabrics were used as a novel platform for cell-based assay and cellmanipulation device.
