Much research has been conducted regarding the causes and impacts of climate change around the world. The current research contributes to the knowledge of the influence of climate change on our environment, with emphasis on earthquake occurrences in the region of Indonesia. Using global temperature anomaly as a measure of climate change, and earthquake data in Indonesia for the period 1900-2022, the paper seeks to find a relationship (if any) between the two variables. Statistical methods used include normal distribution analysis, linear regression and correlation test. The results show peculiar patterns in the progression of earthquake occurrences as well as global temperature anomaly occurring in the same time periods. The findings also indicated that the magnitudes of earthquakes remained unaffected by global temperature anomalies over the years. Nonetheless, there appears to be a potential correlation between temperature anomalies and the frequency of earthquake occurrences. As per the results, an increase in temperature anomaly is associated with a higher frequency of earthquakes.展开更多

This solution is more reasonable than those reported by USGS, Harvard CMT and ERI of University of Tokyo. The best double-couple component of this earthquake is 1.51021 Nm, the compensated linear vector dipole component is 1.21020 Nm, and the explosion component is 5.91019 Nm. The focal mechanism is mainly left-lateral strike-slip, with a small thrust component. Nodal plane I: The strike is 199? the dip, 82? and the rake, 5? Nodal plane II: The strike is 109? the dip, 85, and the rake, 172. P axis: The azimuth is 154 and the plunge, 2; T axis: The azimuth is 64 and the plunge, 10; B axis: The azimuth is 256 and the plunge, 80. The P-waveforms recorded at different stations show prominent directivity. The directivity shows that the Nodal plane I is the fault plane, and that the earthquake ruptured unilaterally from the northeast to the southwest, nearly perpendicular to the strike of the Java trench.展开更多

The formation contains dominant shale at the top, with some sandstone interbeds. Whereas it contains coarse to very coarse sandstone beds at the bottom. The lower sandstone unit also contains carbonaceous shale and some coal seams. The geochemical analysis is important to identify a source rock quality in shale gas. The quality of source rock is determined by richness of the source rock and type of kerogen. 37 samples were collected from well cuttings in JML-1 and JML-2 wells. Samples we are received into the laboratories in the form of well site canned ditch cuttings, bagged ditch cuttings in various stages of preparation from wet, unwashed to dried, washed;sidewall cores, conventional cores, outcrop samples. The richness of a source rock can be defined by the content of organic carbon which is measured as total organic carbon (TOC). Based on geochemical result of analysis, quantity of shale hydrocarbon potential is indicated by the TOC value of 0.52 wt% - 6.12 wt% (fair to excellent criteria), with average of shale thickness more than 50 m. Tmax is an indication of the maturation stage of organic material and Hydrogen Index (HI) is a parameter used to explain the origin of organic material. HI versus Tmax crossplot was analysed for kerogen type determination and presence of type II/III kerogen was identified. This study concludes that the source rock contains abundant humic organic matter that was deposited in a transitional (Fluvio-deltaic) to marginal marine environment under oxic conditions.展开更多

It is observed that before this great earth-quake, there exists an accelerating moment release (AMR) process with the temporal scale of a quarter century and the spatial scale of 1 500 km. Within this spatial range, the MW=9.0 event falls into the piece-wise power-law-like frequency-magnitude distribution. Therefore, in the perspective of the critical-point-like model of earthquake preparation, the failure to forecast/predict the approaching and/or the size of this earthquake is not due to the physically intrinsic unpredictability of earthquakes.展开更多

文摘Objective:To identify circulating HPV types among urban Indonesian women and their specific co-infection patterns in bid to curb HPV infection in the general population and minimize its complications.Methods:Urban Indonesian women from general population were selected as sample framework.Sample size and distribution across regions were determined by the Indonesian Bureau of Statistics(Badan Pusat Statistik,BPS),which represented the national level.Up to 35408 cervical swab specimens were collected from August to September 2016 in 34 Indonesian provinces,categorized into six regions based on the development criteria set by the Ministry of National Development Planning(Badan Perencanaan Pembangunan Nasional,BAPPENAS).From all 1874 samples identified as HPV-positive,hybrid capture was implemented to evaluate type-specific HPV.This study analyzed descriptive data to determine the core-cluster of HPV combination.Co-occurrence HPV network was assessed using‘qgraph’package version 1.6.3 and computed in R version 3.6.3.Two-HPV association was analyzed in logistic regression using bias-reduction generalized linear model(brglm2)package version 0.5.1 adjusted by age and six main Indonesian regions.Results:The logistic regression analysis demonstrated that HPV type 52 had rare relationship despite its common co-occurrence,cementing its role in single HPV infection.HPV type 16 and 18 tended to form infection cluster and were strongly associated with other types.Conclusions:HPV type 52 was the most frequent HPV type among urban Indonesian women and accounted for most single infection cases.Concurrently,HPV 16 and HPV 18 accounted for most multiple infection cases and had strong tendency to attract other types,which may add further complications.However,due to lack of cytology and histological examination and information for other potential determinants,further in-depth studies are necessary to confirm whether these infection patterns truly connect to certain clinical outcomes.
文摘This study used multinomial logistic regression and Bayesian belief networks(BBN)to analyze factors influenc-ing the functionality of the community-based rural drinking water supply and sanitation program(PAMSIMAS)in Indonesia.28,936 PAMSIMAS projects in 33 provinces in Indonesia were analyzed.The data indicates that 85.4%of the water supply systems were fully functioning,9.1%were partially functioning,and 5.5%were not functioning.In the regression analysis,good management is positively associated with functionality and a high investment per capita is negatively associated with the functionality.The latter suggests the need for comprehen-sive economic analysis in the feasibility study in scattered housing sites and remote-undeveloped areas.We also found that high community participation at the beginning of the project was associated with the not functioning system,while women’s participation was positively associated with the functionality.Furthermore,the household connection is more likely to be functioning than communal connection.BBN analysis shows if the beneficiaries do not pay for water,the probability of not functioning systems is 20 times higher than systems with fee collec-tion.Moreover,the combination of strong management,strong financial status,and household connection rather than communal connection increases the probability of fully functioning to 98%.Improvement of data collection is also necessary to monitor the current conditions of all PAMSIMAS systems in Indonesia.This study offers a country-level perspective for better implementation of the community-based rural water supply and sanitation program in developing countries.
文摘To increase the resilience of farmers’livelihood systems,detailed knowledge of adaptation strategies for dealing with the impacts of climate change is required.Knowledge co-production approach is an adaptation strategy that is considered appropriate in the context of the increasing frequency of disasters caused by climate change.Previous research of knowledge co-production on climate change adaptation in Indonesia is insufficient,particularly at local level,so we examined the flow of climate change adaptation knowledge in the knowledge co-production process through climate field school(CFS)activities in this study.We interviewed 120 people living in Bulukumba Regency,South Sulawesi Province,Indonesia,involving 12 crowds including male and female farmers participated in CFS and not participated in CFS,local government officials,agriculture extension workers,agricultural traders,farmers’family members and neighbors,etc.In brief,the 12 groups of people mainly include two categories of people,i.e.,people involved in CFS activities and outside CFS.We applied descriptive method and Social network analysis(SNA)to determine how knowledge flow in the community network and which groups of actors are important for knowledge flow.The findings of this study reveal that participants in CFS activities convey the knowledge they acquired formally(i.e.,from TV,radio,government,etc.)and informally(i.e.,from market,friends,relatives,etc.)to other actors,especially to their families and neighbors.The results also show that the acquisition and sharing of knowledge facilitate the flow of climate change adaptation knowledge based on knowledge co-operation.In addition,the findings highlight the key role of actors in the knowledge transfer process,and key actors involved in disseminating information about climate change adaptation.To be specific,among all the actors,family member and neighbor of CFS actor are the most common actors in disseminating climate knowledge information and closest to other actors in the network;agricultural trader and family member of CFS actor collaborate most with other actors in the community network;and farmers participated in CFS,including those heads of farmer groups,agricultural extension workers,and local government officials are more willing to contact with other actors in the network.To facilitate the flow of knowledge on climate change adaptation,CFS activities should be conducted regularly and CFS models that fit the situation of farmers’vulnerability to climate change should be developed.
