Abstract

Biology is a leading science and a foundation in everyday life for all people. Biology student teachers need to be equipped with biological literacy and critical thinking skills in order to teach biology in the future. This research is aimed at determining the effect of socio-biological case-based learning on biological literacy and critical thinking skills of biology student teachers compared with the traditional learning (lecture-based learning). Socio-biological case-based learning is a model of problem-based learning by placing biological cases as a problem to be explained and solved through a series of investigative activities. This research was a quasi-experimental conducted at the Department of Biology, Universitas Negeri Malang. The research samples were the first year students who programmed the General Biology course, consisting of 29 students as a control group and 33 students as experimental group. This research was conducted in September-December 2015. The data of biological literacy and critical thinking were collected from pre-test and post-test. The data were analyzed using ANCOVA test. The research showed that there was a significant difference of biological literacy and critical thinking skills between the students taught by using socio-biological case-based learning and those taught by using lecture-based learning. The research indicated that the socio-biological case-based learning could enhance the biological literacy and critical thinking skills of biology students teachers.

Abstract

Ex-mining pond water is widely used for the daily needs of the people these days, such as bathing, washing, and even drinking. Over time, it turns out that coal mine acid water has polluted the environment. The use of membrane technology to produce water that meets drinking water quality standards by the Minister of Health Regulation No. 492 of 2010 can be a solution to this problem. The NF270 membrane is a membrane process between reverse osmosis and ultrafiltration, which has a lower flux and operating pressure below 0.2-1.53 Mpa compared to reverse osmosis. Membrane NF270 is used for the reclamation of wastewater, water purification and softening, seawater desalination, and others. Its high rejection of organic molecules with a molecular weight of 200-2000 Da ions and multivalent can remove suspended solids, natural organic matter, bacteria, viruses, salts, and divalent ions contained in water, including coal mine acid water. The purpose of treating acid mine drainage with the NF270 membrane is to remove COD, TSS, TDS, and Fe metals. The NF270 membrane was used in this study to treat the coal mine acid water of PT. Bukit Asam. The performance of the NF270 process was assessed from the effect of pressure (4, 5, and 6 bar) on the flux and rejection rate of each parameter in a single solution, mixed and aqueous coal mine acid solution. The optimum pressure of the NF270 membrane for all parameters was 6 bar. This optimum pressure was then used to compare the phenomenon of flux that occurred and the level of rejection produced in the original sample of coal mine acid water. In the original coal mine acid water, there was a significant decrease in flux due to fouling deposition on the membrane surface. This phenomenon of decreasing flux was caused by fouling and polarization concentration. The rejection rates produced for the parameters of COD, TSS, TDS, and Fe with NF270 membranes were 56.4-93.1%; 78.5-100%; 43-69.3%; 67-100% respectively. Treated coal mine acid water using NF270 membrane technology can be used as drinking water that meets the standards of the Indonesian Ministry of Health Regulation. Thus, NF270 membrane technology can be used to process coal mine acid water into environmentally friendly drinking water.

Abstract

  Beberapa proses pemutihan ramah lingkungan telah diuji-coba sebagai kelanjutan pengembangan proses pemanfaatan tandan kosong sawit (TKS). Pulp TKS dengan bilangan kappa 33 sebagai bahan baku pemutihan disiapkan dengan proses kraft konvensional dan proses etanol yang ramah lingkungan. Pemutihan dilakukan dengan proses ODEoDnD yang bebas Cl2 (elemental chlorine free), serta proses PP dan proses OPOP yang tanpa klor sama sekali (totally chlorine free). Proses konvensional CEDED dengan Cl2 digunakan sebagai pembanding. Pulp putih TKS umumnya memiliki kekuatan mirip pulp putih kayudaun: indeks sobek 6,5-8,5 Nm2/kg, indeks retak 3,5-3,7 Nm2/kg dan indeks tarik sekitar 34 Nm/kg. sayangnya,pemutihan dengan proses PP dan OPOP menghasilkan pulp putih dengan derajad putih hanya sekitar 41% GE. Pemutihan dengan proses ODEoDnD atau proses CEDED menghasilkan pulp dengan derajad putih 80-84%GE. Derajat putih pulp TKS  dari dua proses terakhir ini mirip dengan pulp putih kayudaun (81%GE). Pulp TKS dengan sifat-sifat semacam ini dapat dijadikan bahan baku kertas Koran yang memiliki spesifikasi: derajat putih 57% indeks sobek 4,35 Nm2/kg dan indeks tarik 21 Nm/kg.Kata kunci : limbah organic padat, pulping, emutihanramah lingkungan

Abstract

Makalah ini membahas gabungan proses flokulasi dan membrane mikrofiltrasi untuk pengolahan air gambut. Penelitian dilakukan dengan menggunakan air gambut sintetis  yang dibuat dari humic acid pada berbagai variasi konsentrasi. Validasi dilakukan dengan air gambut asli yang berasal dari daerah Riau dengan kadar organic 168,5 mg/L KMnO4. Sebagai flokulan digunakan FeCl3 dengan jenis membrane hollow fiber polisulfon. Respon yang diamati adalah fluk dan rejeksi kadar organic. Percobaan dilakukan dengan variasi tekanan 0,4-1,6 bar dan konsentrasi flokulan 0-40 mg/L. hasil penelitian menunjukkan bahwa pengaruh tekanan operasi akan meningkatkan fluk. Kenaikan konsentrasi flokulan dari 0-40 mg/L menyebabkan fluk yang didapatkan semakin turun dengan rejeksi kadar organik naik. Kondisi operasi terbaik yang didapatkan yaitu pada tekanan 1,2 bar dan konsentrasi flokulan 40 mg/L untuk air gambut  sintetis, sedangkan untuk air gambut asli pada tekanan 1 bar dan konsentrasi floklan 30 mg/L. Kata kunci : flokulan, membrane mikrofiltrasi, fluk, rejeksi

Abstract

Experimental and modeling studies of the effect of tempetarature on liquid-liquid membrane contactor (LLMC) have been done. The experiments were conducted by varying temperature of 25 up to 80 0C, cross flow velocity from 0.02 to 0.05 m/s and feed concentration of 0, 5000 and 30,000 mg/l. In these experiments microporous hydrophobic hollow fiber polypropylene membrane with 0.2 μm was used as a contacting device. The modeling has been done by compiling mathematic equation of mass and  heat transfers in liquid-liquid membrane contactor. Both the experimental and modeling result show, the increase in feed temperature increase  the flux of pure water exponentially, whereas the flux decrease with increasing the permeate temperature. The feed temperature increase at higher temperature result in hogher flux increase. The concentration of pure water result in the range of 1.8 to 5.6 mg/l depending on feed concentration.Keywords : membrane contactor, modeling
