Analysis of Phenols and Antioxidants Infused Sappan Wood (Caesalpiniasappan L.)

Caesalpinia sappan L. is one of Caesalpiniaceae family found in Indonesia and a health drink that is often consumed by society at large in Indonesia. This study aims to theanalysis of phenol and flavonoid infuse a sappan wood (Caesalpiniasappan L.) and determine the activities of the wooden cup remedy by using DPPH (1,1-picrylhydrazyldiphenyl- 2). Sappanwood extracted using distilled solvent was conducted using infuse for 15 minutes at a temperature of 900C. Extracts infuse obtained analyzed qualitatively using the reactive dye and quantitative determination using spectrophotometry UV-Vis at a wavelength of 730 nm for analysis of phenol in total and 430 nm for analysis flavonoidtotal average level of phenols total of 554,86 mgGAE/L samples and flavonoid total of 1,0377 mgQAE/L samples. Samples wood sappan made with a concentration of 1%, 2%, 3%, 4%, 5% and 6% with the addition of DPPH by using a UV -Visible spectrophotometer. The results showed that the samples of the sappan wood 6% have the highest antioxidant activity at a wavelength of 513.1 nm

THE DEVELOPMENT OF INQUIRY BASED VERTEBRATE ZOOLOGY PRACTICUM GUIDANCE TO INCREASE COGNITIVE AND PROCESS SKILL OF BIOLOGY STUDENTS

The study was a Research and Development that was conducted to produce a valid, practical, and effective Inquiry-based Vertebrate Zoology Practicum Guidance. The study was conducted at Biology Laboratory in Mathematics and Natural Science Faculty of Universitas Negeri Makassar. The subjects were students in Class Biology Science (n=33) as second semester students in academic year 2012/2013. The development of practicum guidance in this study referred to Dick & Carey’s Development Model which consists of 10 stages as follows: (1) Identify Instructional Goals, (2) Conduct Goal Analysis, (3) Identify Entry Behaviours and Characteristics, (4) Write Performance Objectives, (5) Develop Criteria-Referenced Test Items, (6) Develop Instructional Strategy, (7) Develop and Select Instructional Materials; (8) Design and Conduct Formative Evaluation; (9) Design and Conduct summative Evaluation, and (10) Revise Instructional process. The product that had been developed then processed with analysis of validity, practicality, and effectiveness. Based on the result of analysis, Inquiry-Based Vertebrate Zoology Practicum Guidance which had been developed was found to be valid, practical, and effective. Validation result showed that the practicum guidance was included in valid category with validation value of 4.19. The practicality were measured by using observation sheet of practicum guidance feasibility, and the result showed that the aspect of syntax was included in medium category, social interaction in very high category, and reaction principle in high category. Meanwhile, effectiveness of the practicum guidance were measured by using student’s activity observation sheet and practicum final test, the result showed that the average percentage of practicum time is in accordance with the percentage of ideal time and tolerance intervals time. The percentage of students who can pass vertebrate zoology practicum test and final course test is 96.97% and 89.19%, respectively

LOCAL WISDOM OF BAUMATA SOCIETY IN KUPANG IN CONSIDERING THE NATURE PERSERVATION

A research on local wisdom in the nature preservation of Baumata has been conducted from February to March 2014. It held in the Village of East Baumata, Taebenu Sub district, Kupang regency, East Nusa Tenggara (NTT) in order to know what is the local wisdom owned by Baumata villages in the preservation of nature and environment around them. The method used in this research is descriptive qualitative. The data is taken by interviews and direct observation. Researchers explore the village of East Baumata to observe and conduct the interviews with community consisting of the village, traditional leaders, healers (shaman) and ordinary people. The results obtained from this study is clearly wisdom view of local communities Baumata in the preservation of nature, namely the presence of fine custom ('adat sanctions') related actions that damage the environment. Besides that all the families which surveyed, were seen planting and maintaining plants for food, medicine and ornamental plants in the yard. One other interesting thing is all the families surveyed had livestock in the household and their concepts and apply the principles of the triangle of life "mansian - muit - nasi, na bua" which means humans, livestock, and forests is an integral and mutual dependency

Identifikasi Perifiton sebagai Penentu Kualitas Air pada Tambak Ikan Nila (Oreochromis niloticus)

Penelitian ini adalah penelitian deskriptif yang merupakan penelitian survei yang menggambarkan tentang objek yang diteliti yakni jenis perifiton yang ada ditambak ikan nila (Oreochromis niloticus) di kabupaten pangkep serta mengukur parameter kualitas air meliputi parameter fisika-kimia. Fisika yakni suhu, salinitas, dan kekeruhan. Kimia yakni pH dan amonia. Dalam keadaan seimbang perifiton yang tumbuh akan hidup dengan baik. Penelitian ini dilakukan pada 2 tambak dengan cara meletakkan substrat yakni kaca preparat selama 7 hari pada tambak setelah itu dilakukan identifikasi jenis perifiton di laboratorium mikrobiologi FMIPA UNM dengan menggunakan mikroskop optilab. Kemudian mengidentifikasinya dengan mencocokkan dengan buku identifikasi. Jenis-jenis perifiton yang ditemukan pada tambak ikan nila (Oreochromis niloticus) di kabupaten pangkep yakni Amaphora Asterionella, Navicula, Nitzchia, Closterium, Mikrospora, Mougeotia, Rhizoclonium, Zignema, Tribonema

Adherence and Pathogenicity Assay of Vibrio Harveyi in Tiger Shrimp (Penaeus Monodon) Larvae for Screening Biocontrol Agent

Rifampicin-resistant marker was employed as a reporter to detect the adherence and colonization of V. harveyi in shrimp larvae. Vibrio harveyi P1B and YA32.2 were isolated from dead shrimp larvae in Besuki, Northern Coast of East Java, while V. harveyi HB3, was isolated from pristine sea water in Pacitan, Southern Coast of East Java. Vibrio metschnikovii used as biocontrol agent was isolated from healthy shrimp larvae in Serang, West Java. Spontaneous mutation was conducted to generate V. harveyi P1B, YA32.2 and HB3 resistant to rifampicin. These mutants exhibited similar survival ability to their parental (wild type) strains. Significant larval mortality was observed in shrimp larvae inoculated with YA32.2 than that of larvae inoculated with P1B. Larvae inoculated with HB3 showed the lowest mortality. Bacterial cell count of Vibrio Rf* in dead larvae were 103-104 cells/larvae. Isolates of Vibrio metschnikovii Z and M as biocontrol candidates effectively reduced the growth and adherence ability of YA32.2 to shrimp larvae. Larval mortality in rearing water inoculated simultaneously with YA32.2 and V. metschnikovii was lower than the one inoculated with YA32.2 alone. Therefore, Vibrio metschnikovii Z or M could be developed as an effective probiotic or biocontrol agent for V. harveyi in shrimp hatcheries
