Pengolahan Limbah Cair Industri Alkohol Bekonang Menggunakan Proses Fermentasi

This study aims to determine: (1) Wastewater treatment Bekonang alcohol industry using fermentation methods; (2) The content of wastewater alcohol Bekonang; (3) Glucose levels contained in wastewater alcohol Bekonang; (4) The optimum time alcoholic fermentation of liquid industrial waste Bekonang to produce the highest ethanol content. This study used an experimental method. Alcohol industry wastewater comes from Sembung, Bekonang, Mojolaban, Sukoharjo . The first step is to test the alcohol industry wastewater Bekonang with benedict test, Seliwanoff's test and the iodine test. Then analyzing glucose levels using Somogyi Nelson method. The second stage is fermentation process, namely in the form of liquid waste mixing with 0,529 grams of urea, NPK much as 0,106 g and 0,212 g Saccaromyces cerevisiae as to the erlenmeyer. Erlenmeyer sealed and allowed to stand for 24 , 48 , 72 , 96 and 120 hours. For the standing variation, waste water settling in advance for 2 , 6 and 10 days and then fermented for 96 hours . The third stage is the process of distillation of the fermented at a temperature of 70-800C. The last stage is to determine the concentration of ethanol by using Gas Chromatography (GC) by comparing the area of standards and an area of the sample. Based on this study it can be concluded that : (1) Waste water treatment Bekonang alcohol industry can use the method of fermentation to produce ethanol again; (2) Alcohol industry wastewater containing dextrin identified by test benedict , Seliwanoff's test and test iodine; (3) Glucose contained in wastewater alcohol Bekonang is 1,3285 %; (4) The optimum time alcoholic fermentation of liquid industrial waste Bekonang is 96 hours due to ethanol results obtained showed the highest ethanol content is 81.83 %

SETS (Science, Environmental, Technology And Society ) sebagai Pendekatan Pembelajaran IPA Modern pada Kurikulum 2013

Dalam dunia pendidikan mulai diintegrasikan pendidikan berwawasan lingkungan, misalnya Pendidikan bervisi SETS (Science Environment Technology and Society) dimaknakan sebagai sains, lingkungan, teknologi, dan masyarakat, merupakan satu kesatuan yang dalam konsep pendidikan mempunyai implementasi agar anak didik mempunyai kemampuan berpikir tingkat tinggi (higher order thinking). Pendidikan bervisi SETS akan membimbing peserta didik untuk berpikir global dan bertindak lokal maupun global dalam memecahkan masalah-masalah yang dihadapi sehari-hari. Masalah-masalah yang berada di masyarakat dibawa ke dalam kelas untuk dicari pemecahannya menggunakan pendidikan SETS secara terpadu dalam hubungan timbal Balik antar elemen-elemen sains, lingkungan, teknologi, masyarakat. Dalam implimentasi kurikulum 2013 dalam pembelajaran IPA dengan pendekatan SETS di sekolah wawasan SETS yang diaplikasikan ke dalam proses pembelajaran IPA dapat menerapkan pengetahuan yang diperoleh siswa guna meningkatkan kualitas hidup manusia tanpa harus membahayakan lingkungannya.

Keanekaragaman Makro-invertebrata di Pantai Sepanjang, Gunungkidul, di. YOGYAKARTA

Macroinvertebrates is one of bioindicator for aquatic ecosystem. By assessing indicator species, diversity, functional groups of macroinvertebrates community, it is possible to determine water quality. Purpose of this research was to inventory and study the macroinvertebrates species diversity in Sepanjang Beach, Gunungkidul, Yogyakarta. This research was conducted on Wednesday, November 25th 2014 at Sepanjang Beach, Gunungkidul, Yogyakarta. Sampling points was determined by line transect method. At each transect, sampling with 1x1 m2 plots was done. The data obtained in this study was the result of macro-invertebrates species inventory in each sampling point and the number of individuals of each species. Data analysis was performed by calculating the Shannon-Weiner diversity index (H'). Result of this research showed that there were 63 macroinvertebrates species with 1033 number of individuals found in Sepanjang beach. Result of calculation of Shannon-Weiner diversity index (H') showed the diversity index of macro-invertebrates in Sepanjang beach was 1.24. The diversity index showed that the diversity index of macro-invertebrates in Sepanjang beach categorized by medium diversity.
