The identification and conservation method used in this study is RUSLE and the conservation model used is sengon-coffee intercropping. The effeciveness criteria used is erosion yield on the field decreases until low level of erosion hazard level (below 60 tons/hectares/year). The 208 samples of sengon plantations were used to identify erosion yield and the results show that 75.9% of sengon plantations in Tanggul watershed have moderate to very high erosion hazard level with an average erosion yield at 257.49 tons/hectares/year. While simulation of scenario 1st, 2nd and 3 rd intercropping conservation model resulting erosion yield 158.2; 131.8; and 97.7 tons/hectares/year respectively. In this case, 3rd scenario is effective to reduce erosion yield to low level of erosion hazard level by 65% of total plantations. However, other conservation model still needed to be added in the sengon plantation to reduce erosion in low hazard level.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"63 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41295464","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}

Ninety percent of this area is covered by the sea with 3 unique tropical coastal ecosystems, namely mangroves, seagrass, and coral reefs. This high productivity ecosystem provides various goods and environmental services in fisheries, tourism, and other industries. One of them is coastal resources such as Julung julung fish (Half-beak, Hemirhamphus spp) that use this ecosystem for their primary habitat. Unfortunately, little is known about the interaction between Julung-julung and their habitat. This paper aims to assess the changes of the coastal ecosystem of the SBT and their impact on Julung-julung resources. Two satellite images of Landsat-7 ETM+ (2001) and Sentinel-2A (2018) were analyzed to monitor the condition changes of mangrove and seagrass. Six habitat classes of sea, land vegetation, mangrove, dense, medium, and sparse seagrass were classified using isocluster analysis, validated using ground truth data collected during intensive field survey, and then the areas of each habitat class were calculated. From the period of 2001 to 2018, the areas of mangrove and seagrass have decreased from 1401.5 to 1118.8 ha, and from 3183.8 to 2509.4 ha, respectively. The decrease of mangroves was due to mangrove cutting for firewood that use to smoke Julung-julung, one of the famous fish products from the SBT, while mining dead coral for building materials in seagrass beds decreased their areas. Interview with experienced SBT’s fishers in catching Julung-julung showed that the population of this fish has decreased by about 30-50% within 20 years, which was most likely due to the impact of their habitat degradation. In contrast, the decrease of Julung-julung stocks in other province was mostly due to overfishing. Thus, maintaining, conserving, and revitalizing the mangrove and seagrass ecosystems in the SBT as the important habitat for the early life history of Julungjulung is inevitable, as well as it is necessary to immediately conduct in-depth study on biological and population dynamics of this fish, whose data is still lacking, so that the Julungjulung stocks can manage sustainably.\"","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46621546","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}

Aim of the study is revealing what kind of different risks restoration works carry, creating awareness and making recommendations for avoiding these risks. As method of this study, Fine Kinney Method was chosen. The risk factor was obtained by using probability, severity and frequency values. Listed masonry houses from Fatih district were chosen. The region is composed of civil architectural examples more densely comparing to whole Istanbul. The most important criteria is the fact that these houses are among the oldest masonry examples in Istanbul. They carry more risks with their current deterioration levels. The possible risks were listed and documented. The results were presented using Fine Kinney Method. Falling from height and partial collapse are found as main risks in restoration works. Risk levels and risk types of potential risks in restoration works show differences than the standard construction applications.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46211673","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}

Therefore, alternative methods are needed. This study attempted to solve these problems by reducing the amount of orpiment and lead white by mixing other pigments. The specimens were prepared by mixing orpiment with two types of yellow ochre and one each of oyster shell white and white clay. Lead white was mixed with three types of oyster shell white and white clay. Surface changes, chromaticity, and peeling characteristics were observed. When orpiment was mixed with white pigments, the mixture showed a relatively similar to the orpiment color, compared to when mixed with yellow ochre. When orpiment inside the film was discolored, however, the yellow index was reduced by 20 at most, showing a high color difference value. When orpiment was mixed with yellow ochre (5:5), the mixture was observed to have relatively high chromatic stability and durability, compared to when orpiment was solely used.

White porcelain fired at 800℃ showed high intensity TL signals over a wide temperature range of 100 to 400℃, whereas white porcelain fired at 1200 and 1350℃ showed TL peaks at 100 and 210℃. Moreover, the OSL signals of white porcelain fired at 800℃, increased linearly according to the amount of irradiation, under IR, orange, green, blue and UVA stimulation. However, the OSL signals of white porcelain fired at 1200℃ increased linearly only under blue and UVA stimulation, while those of white porcelain fired at 1350℃ increased linearly only under UVA stimulation. In general, the strength of the TL/OSL signal was weakened as the firing temperature increased, which seems to be due to the vitrification caused by the high-temperature firing process. Therefore, it was found that it is important to select the optical stimulation source of the proper wavelength during TL/OSL dating to white porcelain.","PeriodicalId":45840,"journal":{"name":"International Journal of Conservation Science","volume":"32 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86818590","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}
