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

Neonatal sepsis is one of several most common causes of neonates mortality in developing countries. Neonatal sepsis is defined as a disseminated disease with positive blood culture during the first month of life. The aim of this study was to find how many cultures presented positive and negative results and also to detect the most common bacterial causes of neonatal sepsis and determination of their sensitivity to antibiotics. This research design using a descriptive study with retrospective approach. The sampling technique is performed by total sapling method adn the amount of sample is 568 blood cultures which 196 reported as positive (34,51%) and 372 reported as negative (65,49%). The most common isolated bacteria were coagulase negative Staphylococcus (29,08%), Burkholderia cepacia (12,76%), Acinetobacter baumanii (9,18%), Klebsiella pneumoniae (8,16%), Escherichia coli (4,08%) and, Enterobacter aerogenes (4,98%). Neonatal sepsis caused by infection of coagulase negative Staphylococcus can be treated by vancomycin, linezolid and tigecycline

Hubungan Antara Konformitas Dengan Motivasi Belajar Pada Siswa Di SMA Muhammadiyah Kudus

Penelitian ini bertujuan untuk mengetahui hubungan antara konformitas dengan motivasi belajar pada siswa SMA Muhammadiyah Kudus. Populasi penelitian ini adalah siswa di SMA Muhammadiyah Kudus sebanyak 294 orang. Sampel penelitian sebanyak 177 orang, sampel diambil dengan menggunakan teknik cluster random sampling. Pengumpulan data menggunakan dua buah skala psikologi yaitu Skala Motivasi Belajar (40 aitem valid, α = 0,955) dan Skala Konformitas (39 aitem valid, α = 0,941). Hasil penelitian ini menunjukkan koefisien korelasi rxy 0,495 dengan p = 0,000 (p<0,001). Hasil tersebut menunjukan bahwa hipotesis yang diajukan peneliti yaitu terdapat hubungan positif antara konformitas dengan motivasi belajar dapat diterima. Nilai koefisien korelasi positif menunjukkan bahwa arah hubungan kedua variabel adalah positif, artinya semakin tinggi konformitas maka semakin tinggi motivasi belajar. Konformitas memberikan sumbangan efektif sebesar 24,5% pada motivasi belajar dan sebesar 75,5% dipengaruhi oleh faktor lain yang tidak diteliti dalam penelitian ini
