The benefits of S. cumini plants include seeds as a cure for diabetes, fruit as an antioxidant and anticancer, fruit skin as a medicine for dysentery and leaves as a reinforcement of teeth and gums. 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). While The stem and leaves wet weight and stem and leaf biomass comparison from the highest were Gunungkidul (6.84 gram, 2.10 gram), Yogyakarta (4.95 gram / 1.59 gram) and Cikampek (4.24 gram / 1.47 gram). Moreover, seeds from the Gunungkidul population produced better growth than other populations. This study's recommendation is to develop rare plants of S. cumini species that will have the best growth by using seeds from the Gunungkidul","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87529712","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}

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 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}

This technique requires rootstock and scion. The high rootstock demand for the replanting program drives the seeds’ suppliers to collect assorted seeds from cultivated fields, lead to a high variation in the germination rate. The time from seed dehiscent to seeding was hypothesized to be crucial inflicting an inconsistency in the germination rate and seedling rootstock growth. This present study used rubber seeds of the GT1 clone which were laid under trees’ shading to mimic the natural environment. Five laying periods were applied i.e., P0 (directly germinated, control), P1 (laid for one week), P2 (laid for two weeks), P3 (laid for three weeks), and P4 (laid for four weeks). Our study implied that the direct sowing after dehiscent was the best way to attain a high germination rate (GR) (51.67%) while delaying seed sowing for one week reduced the GR up to 22.04%. The longer delaying in P2, P3, and P4 did not show significant differences among them which were 13.33%, 1.19%, and 4.35% respectively. However, the seedling showed a similar growth rate including root/shoot ratio regardless of the laying period treatment. The necessity of establishing seed gardens for rootstock was highlighted in which the harvesting of the seeds could be controlled.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81924807","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}
