Those villages represented lowland and upland area respectively. The objective of the study was to identify the diversity of plants species at family home gardens in those areas. Data was taken from 10 home gardens in each village. Primary data was collected by direct observation to the home gardens and interview with the householders, while the secondary data obtained from literature study. Data was analyzed using D and D method. Result showed that 57 plant species were conserved on-farm at the home gardens in Jampang and 58 plant species in Cisarua village. Fruit plant was dominant species in Jampang while in Cisarua was ornamental plants.","PeriodicalId":270221,"journal":{"name":"Bumi Lestari Journal of Environment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124691449","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 problem even causes more serious life-threating phenomenon because water is one of the main resources for energy circulation. Whether change anomalies have brought about impacts on seasonal shift on several islands of Indonesia, including those in East Nusa Tenggara province. These islands experience drought. Fresh water availability for industry and domestic use in cities like Kupang has been a serious problem. This issue becomes worse in recent years due to significant increase of city population. Public responsibility to maintain natural environment and resources is therefore required. This study tries to investigate public concerns over the water shortage issue in order (1) to know to what extent public is willing to pay their consumption of fresh water provided through Sub-DAS Kali Dendeng; and (2) to analyze factors that influence the willingness of the fresh water consumers to pay for environment services provided at Sub-DAS Kali Dendeng. Quantitative approach which relies on primary and secondary data gathered through interview and field observation is applied in this study. The data were analyzed by using Dichotomous Choice CVM, Turnbull Method, and Logistic Regression to find out WTP value. The results of this analysis are described within the environmental science perspective to find out the relationship among various factors for being water consumer responsibility towards water resources preservation at Sub-DAS Kali Dendeng in Kupang. The results of the analysis show that the willingness to pay for fresh water by consumer at Kelurahan Manutapen, Mantasi dan Airmata is significantly high. They are willing to pay between Rp. 3.362 to Rp.11.328 according to WTP calculation. This amount is much higher than that determined by the city freshwater supplier company (PDAM). The facts for the reason why the consumers are willing to pay for higher amount for fresh water supply are determined by several factors; they include bidding value, consumer’s level of education, consumer’s income, water quality, and the amount of the family members. These factors simultaneously influence the water consumer willingness to pay for the water they consume; and this willingness factor has significantly high impacts as seen in Negelkerke R. Square value at 0,600, or being comparable to 60%; meaning that various factors of 60% in Y are able to explain all free variable in X. Respondents for this study are those who use fresh water supplied from Sub-DAS Kali Dendeng, and those who reside around the Sub-DAS Kali Dendeng. It is believed that there must be more citizens around the Sub-DAS Kali Dendeng, who also contribute negative impact toward the ecological environmental change, yet these individuals have no direct responsibility, and therefore the responsibility for the environmental conservation examined trough this study might not be thorough","PeriodicalId":270221,"journal":{"name":"Bumi Lestari Journal of Environment","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124581967","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}

The large magnitude of natural forces involved in landslides makes actions of mitigation or prevention unfeasible, with exceptions for minor occurrences or under special conditions. Many old methods have been applied in landslide management and/or prediction, such as overlays or weighting methods. The newest/advanced methods are still being developed and one of the newest methods is Artificial Neural Network (ANN). ANN are biologically inspired computer programs designed to simulate how the human brain processes information. Many types of ANN exist; the most famous one is Multilayer Perceptron (MLP) Neural Network Algorithm with FeedForward model. MLP consists of three parts: the input layers as neurons representing the value of data; the hidden layer, which demonstrates the network training process; and the output layer, which provides the prediction of the landslide areas. In this research, the input layer consists of landslide location characteristics, such as the rainfall intensity, land cover, slope, geological types, and rate displacement of landslides. As a case study, Bangli Regency was selected. In 2017 there was a landslide disaster in the Kintamani District, Bangli Regency, which resulted in dozens of people missing or dead, and several houses destroyed. In this study different numbers of neurons were used in the hidden layer (15, 50, 100, and 150 neurons). The best performance is obtained at 150 neurons, with 0.9677 (96,77%) for the test set.","PeriodicalId":270221,"journal":{"name":"Bumi Lestari Journal of Environment","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134435981","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}
