Get PDFText book owned by the Biological Library of FMIPA UNM able to fulfill 70% requirement of student literature and 100% requirement teach by the teacher. Along with science progress in biological area, text book owned by the library require to be improved. But addition sum up the book did not correct solution because the addition sum up the book need the broader place, more amount time, and larger ones energy to manage the books. Biological Library of FMIPA UNM have the additional service that is service free acces internet. To assist the student to search of online study literature, researcher conduct the mentoring toward library visitor (student). This mentoring will know: "How many improvement of library visitor in Biological Library of FMIPA UNM after mentoring online library?". Research method is: research of literature, observation, mentoring, quetionnaire, and evaluation. Result of research find that after mentoring the amount of library visitor have increase so much. This matter caused by almost the all visitor did not yet known searching of book online and also the book fulfill requirement of academic student. Therefore to increase service of Biological Library of FMIPA UNM, the management must provide free access the internet, computer, speed access, and mentoring base on the requirement of academic student.
Analisis Kadar Etanol Hasil Fermentasi Ragi Roti Pada Tepung umbi Gadung (Dioscorea hispida Dennst) terhadap kadar etanol
Get PDFThe research aims to know the long influence of fermentation with bread yeast in Dioscorea hispida flavor to ethanol production. This experiment research was doing in Balai Besar Labolatorium Departemen Kesehatan RI (BBLDKRI), Makassar. The sample of the research was 250 g in every sample of Dioscorea hispida flavor. It had done by chemical by use HCl which boiling in 120°C. This research used 4 M HCl which repeat in 3 times. The result of hydrolysis was 48 hours, 96 hours, and 144 hours. This research used free variable that is the long time of fermentation and variable that was the ethanol value of Dioscorea hispida that had fermented. This research used random complete planning and picnometer was used to know the ethanol value and match it at the kind of the weight table. The result of data analysis showed that the ethanol value in Dioscorea hispida flavor which fermented is 0.0% control); 0.5% (48 hours); 1.1% (96 hours), and 3.6 % (144 hours). The result of this research showed that there was the long influence of the fermentation to the ethanol value in Dioscorea hispida flavor fermentation and after doing the inferential technique analysis and between control and treatment proved that the last fermentation is obvious different with the ethanol value. So, can be concluded that longer time that used in fermentation (144 Hours), higher the ethanol value (3.6 %) in the (Dioscorea hispida).
Analisis Ekologis Meiofauna Interstisial di Sekitar Pulau Pannikiang, Kabupaten Barru
Get PDFMeiofauna were organisms that live in the interstitial. Synonyms were meiobentos. Meiofauna can also be interpreted as a small group of metazoans that sits between microfauna and macrofauna. This was caused by a very small body size and position was hidden in the sediments and did not provide direct benefits to humans (economic benefits). Meiofauna generally known only by scientists who pursue marine biology and ecology. This study aimed to determine the ecological water quality index based on the island of interstitial meiofauna Pannikiang, Barru district. The results showed that the class was the class that dominates the nematode composition and density of meiofauna in Pannikiang Island. Nematodes were very instrumental in the classroom enrich and enhance the productivity of aquatic ecosystems. Based on the ecological value of the index, the index of diversity (H'), Uniformity (E), and dominance (D) showed that P. Pannikiang have good water quality with the diversity of species and the spread of the number of individuals of each species were equal, a unified community and did not find any species that dominate the surrounding waters. Meiofauna ecology index indicates that the water condition in P. Pannikiang not currently experiencing a very severe ecological pressure, meaning that in a stable community structure, environmental conditions is excellent. Therefore, we need public participation and coordination among agencies in the District. Barru to maintain the condition of these waters
