Ants are organisms that can react when there is a change in their habitat. Because of its abundance, its important functions, and complex interactions with the ecosystems it occupies. Ants can be used as bioindicators in environmental assessment programs, such as forest fires, vegetation disruption, deforestation, climate change, mining, waste disposal, and land use factors. Ants are capable of marking environmental degradation and climate change, as they are very sensitive to climate change in their habitats. The study was conducted on the Sirimau Forest at Ambon. The role of ants in the ecosystem will be disrupted when habitat changes occur, so this study aims to find out the forms of introduction that occur in the forest area on the island of Ambon, how ants react to climate change, ant diversity and examine the role of ants as an indicator of climate change. Approaches are made to biotic components (vegetation and ants) as well as abiotic components (soil temperature, air temperature and air humidity). The results of the field inventory found 28 types of ants, 3152 individuals where Odonthoponera tranversa infuscate, Oecophylla smaragdina SUENITIDA, Hypoponera bugnioni are dominant with a species richness value of 3.35, 3.57 species density and 1.29 species diversity with an NOVI value with a vegetation cover area of > 60% in classes 6-9. The highest vegetation diversity was 1.17. Studies at soil temperatures and organic matter content show that soil temperatures vary between 25-27 °C and this is correlated with the area of vegetation cover shown in the NOVI results. The impact of damage and changes to the protected forest ecosystem on ants varies widely. Ants are colonized animals that will die due to changes or damage to the ecosystem, of course it can be explained as colony extinction in the ecosystem.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73982192","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}

From this research it is expected to obtain UK 3A analogues compound that higher yield, more economic and hight activity. The purpose of this study was to synthesize PSEHE compounds which have anticancer and antidiabetic activity. The synthesis of these compounds were carried out in two step reactions. The first step was amidation L-serine ethyl ester hydrochloride with β hydroxypicolinyc acid to produce with β hydroxyl picolinyl serine ethyl ester (PSEE). The second step was esterification of β hydroxyl picolinyl serine ethyl ester with heptanoic acid used DCC and DMAP in chloroform to produce PSEHE. Preliminary analysis was carried out with thin layer chromatography (TLC) and followed by purification using extraction, and the column chromatography on silica gel, eluted with n-hexane and ethyl acetate. Subsequently synthesis product were identified using LCMS Spectrometry, FTIR spectrophotometer, 1H-NMR and 13C-NMR. The pure compound of PSEE from the first step was 85.22% and afterwards pure compound of PSEHE from the second step were 94.48%. The result of toxicity test using Brine Shrimp Lethality Test shown that PSEHE with value LC50 933.25 ppm. The results of cytotoxicity test using Murine Leukemia P-388 cells shown that PSEHE with value IC50 38.0 µg/mL and and the percentage inhibition against to α-glucosidase with value 88.7%.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72730816","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}

However, its hydrophobicity and the short period of efficacy due to rapid degradation in the presence of UV light and air have limited its application as an insecticide. This study studied the effects of hydrophobic alkyl groups on encapsulation and controlled release of rotenone by amphiphilic chitosan derivatives namely, octyl glycol chitosan (OGC) and lauryl glycol chitosan (LGC) were assessed. The physical and chemical properties of OGC and LGC were characterized using Fourier Transform Infrared (FTIR) Spectrometer, CHNO Elemental Analyzer, UV-Visible Spectrophotometer, Fluorescence Spectrofluorometer, and Differential Scanning Calorimetry (DSC). The efficiency of OGC and LGC to encapsulate for rotenone in its micelles was determined by using a High-Performance Liquid Chromatography (HPLC). FTIR and CHNO elemental analyses confirmed the amphiphilic chitosan derivatives were successfully synthesized using the reverse micelles method. The finding from the solubility study shows that the addition of the glycol group to the chitosan backbone has enhanced chitosan’s solubility properties in neutral and basic media. OGC and LGC exhibited good affinity towards rotenone with an encapsulation efficiency of more than 90%. The in vitro release study showed that the OGC and LGC could control the release of rotenone from its micelles. This study demonstrates that OGC and LGC showed beneficial properties to be further developed as a potential carrier in the pesticide formulation.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82745000","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}
