This research was conducted for three months, from June to August 2020 in Teteaji Village and Wette'e Village, Sidenreng Rappang Regency. This study aims to determine the effect of fishing effectiveness and the status of the sustainability of the management of Lake Sidenreng. The effect of population explosion on the effectiveness of fishing was analyzed descriptively based on a comparison of the production of moderate catches on the sustainability status of Sidenreng Lake management using the RAPFISHMDS (Rapid Appraisal for Fisheries-Multidimensional Scaling) method. Based on the analysis of the suckermouth catfish population explosion in Sidenreng Lake, it has an impact on capture fisheries activities in Lake Sidenreng, namely on fishing gear, fishing operations and production of catches.

As dental implant material, the biocompatibility of CHA is an important prerequisite factor. This study aims to determine the biocompatibility of CHA on zebrafish embryos. The zebrafish embryos treatment was carried out on 3 hours post-fertilization (hpf) embryos aged. The embryos were exposed to CHA with concentrations of 15 μg/ml, 125 μg/ml, 500 μg/ml, and 2000 μg/ml, respectively. Biocompatibility assessment was carried out by measuring the hatching rate, survival, morphological changes, and embryo physiological performance, respectively. The hatching rate was determined as the number of embryos that hatched at 48, 72, and 96 hpf. The survival rate was determined by the number of live embryos at 24, 48, 72, and 96 hpf, respectively. Moreover, the morphological change was observed on the shape of the embryo’s heart and yolk, as well as the tail-yolk detachment as an indicator of a normal body wall occurrence, respectively. Moreover, the physiological performance was decided base on the heartbeat rate performance of the embryos. The result showed no effect of CHA on the hatching and survival rate as well as embryo morphology in all treatments. All embryos heart laterality was normally formed, and the tail-yolk detachment occurred at the period of 24 hpf, which indicated normal development of the embryo. The heartbeat rate showed no differences between CHA treatment compared to control, where the embryo heartbeat rate in all treatments was more than 200/minute, indicating normal embryos development.

This research aimed to study the effect of seed population sources on the growth of S. cumini seedling. Seed exploration was carried out in 3 different S. cumini habitats, (1) Gunungkidul District (2) Yogyakarta District and (3) Cikampek District. CRD (Complete Random Design) was used with each population consisting of three replications (50 seeds/replication). The seed source showed significantly different results on the growth of S. cumini seedlings (height, diameter, number of leaves, wet weight of stem and leaves and dry weight of stem and leaves). However, the variation of seed sources did not significantly differ on survival, root wet mean, root dry weight, top-root ratio and seed quality index. Height, diameter, number of leaves, comparison starting from the greatest were Gunungkidul (30.42 cm / 2.93 mm / 21.42), Cikampek (24.64 cm / 2.82 mm / 21.06) and Yogyakarta (21.27 cm / 2.45 mm / 19.27).

One of them is the platelet-derived growth factors (PDGF) gene that have a role in the wound healing process because it induces cell mitosis and thereby causes cell proliferation. PDGF protein expression is thought to chemotactically recruit many cell types including smooth muscle, fibroblasts, and monocytes to migrate to the wound site. These research aims are to analyze the role of PDGF gene expression in the process of digit tip mice tissue regeneration. This study used 24 mice (Mus musculus) were amputated at the digit tip and the growth was observed on days 0, 1, 3, 5, 10, 15, and 25. We isolated RNA from each tissue after amputation on days 0, 1, 3, 5, 10, 15, and 25 and analyzed the RNA expression of the PDGF gene using the qPCR method. PDGF gene expression reached its peak on day 10 on the granule phase and decreased until day 25. The peak expression of the PDGF gene indicates the role of the gene in the tissue regeneration of digit tip mice.

This research was conducted to explore the potential of beach sand as an alternative raw material to replace commercial silica. To obtain the natural silica, the beach sand was prepared and extracted into mesoporous silica. The reflux method was chosen to extract silica using NaOH solution, HCl solution, and CTAB surfactant. The mesoporous structure was potentially affected by CTAB and SiO2 ratio, and therefore, this research was focused more on the effect of CTAB weight variation (3; 4,5 and 6 g). Several instruments were used to analyze the characteristics of silica, such as Surface Area Analyzer (SAA), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR). The mesoporous silica has siloxane (Si-O-Si) and silanol (SiOH) functional group and showed a coral reef-like structure. The porosity properties of these materials ranging from 300-385 m2/g for the specific surface area, 5-8.8 nanometer for pore diameter, and 0.4-0.8 cm3/g for pore volume. Optimal CTAB weight found to be at 6 g, which produces the mesoporous silica with a surface area of 385.928 m2/g, an average pore diameter of 6.015 nanometers, and pore volume of 0.579 cm3/g.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"166 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84648770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
