Abstract

Sea worms have enormous potential to be used as alternative food ingredients because they have a fairly high protein content. The Research of the analysis yield and phytomomic compounds of Eunice Siciliensis marine worms has never been done. An effort to develop Eunice siciliensis sea worm-based alternative food ingredients is important to do phytochemical screening. This study aims to identify phytochemical compounds found in Eunice siciliensis marine worms and find out their benefits for health. This study was analyzed descriptively. The results showed that extract yield was 17.97% and Eunice siciliensis sea worm extract contained alkalaoid, flavonoids, saponins, triterpenoids / steroids, and tannins.

Abstract

The structure of wing scales in four species of papilionid butterflies were investigated. The aim of this study was to determine the differences of wing scales structure from four species butterflies in Superfamily Papilionoidea. Small fragments of wings vein M1 and M2 were cut and observed using Scanning Electron Microscopy (SEM). The wing scales had two types, i.e. rectangular and triangular. Microstructure of wings scales also had many forms consist with window, crossribs, and ridges. All scales of the wing of butterflies observed had different forms (scales, microstructures, and serrations), eventhough the point of viewd were the same. Only Catopsilia scylla had two types scales and Arhopala araxes had different forms of microstructures.

Abstract

The structure of wing scales in four species of papilionid butterflies were The research about the condition of coral reefs in Baranglompo and Bone Batang island was conducted in January to April 2016 based on “Coralwatch” table. The aim of this study was to determine health condition of coral reefs in Baranglompo and Bone Batang island. The data was obtained in the south, west, and north at a depth of 3 meters and 10 meter using Line Intercept Transect (LIT) method along 100 meters of both islands. The health condition of coral reefs was obtained from four coral colony types specifically Branching, Massive, Tabulate, and Soft coral using Coralwatch method. The results of this study showed that the health condition of coral reefs in Baranglompo and Bone Batang islands was still relatively equal. At a depth of 3 meters, the most healthy coral colony was dominated by branching corals while at a depth of 10 meters dominated by massive corals. However, the average value of coral colors indicating coral condition showed that the health condition of coral reefs in Baranglompo was higher than that in Bone Batang island. High anthropogenic impacts were observed by the trash commonly found in Baranglompo island, many fish bombings also found in Bone Batang island. This study recommend that the health condition of coral reefs in Baranglompo island was greater than that in Bone Batang island.

Abstract

This study aims to determine the effect of probiotic administration encapsulated on the cholesterol content of egg laying eggs. Probiotics are given to laying hens (phase layer), once a day for 4 weeks orally. In this study a completely randomized design (CRD) was used with three treatments, namely, probiotic encapsulated lactic acid bacteria (BAL) (E1), commercial probiotics (E2), and without probiotics (E0) with 4 replications. The variables observed in this study were encapsulated probiotic viability, egg weight (g), egg index (%), and total egg cholesterol content (mg / g). The results showed that the viability of probiotic bacteria decreased by 3.34 cfu / g after 4 weeks of storage at 4OC. Average egg weight at E0; E1; and E2 are 62.63 g, 62.67 g, and 64.15 g. Average egg index at E0; E1; and E2 are 71.13%, 75.54%, and 77.2%. The average cholesterol content at E0; E1; and E2 is 3.75 mg / g, 3.25 mg / g and 3.25 mg / g. The administration of encapsulated probiotics did not affect the quality of egg weight but it affected the egg index and total cholesterol content of egg laying eggs.

Abstract

Silver nanoparticles have been synthesized using kluwak leaf extract (Pangium edule Reinw) as bioreductor and antioxidant activity assay. The nanoparticles formed were monitored by observing UV-Vis absorption and characterized by using FTIR, PSA, XRD and SEM instruments. The result of functional group characterization with FTIR show that the functional groups OH, C = O, C-O and CH2 act as Ag+ reducing agent. The size of silver nanoparticles was determined by using Particle Size Analyzer (PSA) and the result show average particle size distribution of 93.2 nm. Morphology of AgNp were observed by Scanning Electron Microscope (SEM) and X-Ray Difraction (XRD) analysis show result of 51,78 nm. The antioxidant activity was shown by in kluwak leaf extract and silver nanoparticles with IC50 values respectively 831,33 ppm dan 1493,09 ppm.

Abstract

Research on the analysis of the anatomy of the stomatal and trichomes of the medicinal plant Dandang Gendis Clinacanthus nutans (Burm.f.) Lindau in Makassar City. This study aims to determine the anatomical structure of the stomatal and trichomes of longitudinal cross-section of leaves that are used as herbal medicines. This research method was used to spread acetone to obtain stomatal prints on the leaf surface, the data were analyzed descriptively. The results of the analysis of the anatomy of the stomatal and trichomes of leaves of the medicinal plant Dandang Gendis Clinacanthus nutans (Burm.f.) Lindau was a diacytic type of stomatal, the spread of stomatal was only found on the surface of the abaxial leaf including the apple type. The number of abaxial stomatal was 160 stomatal/mm2. The number of epidermal cells was 748 epidermis/mm2 and abaxial 504 epidermis/mm2, stomatal index 23.95%, and stomatal size 159.26 µm. On the adaxial and abaxial surfaces of the leaves of Dandang Gendis Clinacanthus nutans (Burm.f.) Lindau, glandular and lithocyst trichomes were encountered.

Abstract

This research is the phenotypic characteristics and grouping of hybrid waxy corn Zea mays L. product of the top cross had been carried out in the experimental plant Indonesian Cereals Research Institute (ICERI) in Maros South Sulawesi. This research aims to determine the phenotypic characters of the hybrid of waxy corn Zea mays L. product of the top cross and grouping based on its phenotypic characteristics. This research used a randomized block design (RBD) with 17 th treatments (corn strains) and three replications. Waxy corn strains used were: URI 1 (G8), G8G1, G8G2, G8G3, G8G4, G8G5, G8G6, G8G7, Soppeng (G10), G10G1, G10G2, G10G3, G10G4, G10G5, G10G6, G10G7, and Paramitha.. All data (qualitative and quantitative) are arranged in binary tables and grouped using the NTSYST program. The observations show that the data obtained comes from 14 quantitative characters and 17 qualitative characters. Quantitative data from 14 characters were tested and the results of 10 characters were significantly different and the other 4 were not significantly different. The grouping results show that the 17 corn strains studied formed 3 groups at the similarity coefficient of 0.76. Soppeng's corn is different from the others.
