Abstract

Bogor is one of the cities in Indonesia with a dense population and is experiencing population growth every year. Like other city problems, waste is also a problem in Bogor City. Waste generation in cities like Bogor City has been continued to increase since 2005. Even though the Bogor City Government has socialized with changes in waste management with a new paradigm, those living in residential areas are still using the old paradigm principle which is collect-transport-throw (end of a pipe). Therefore, a study was conducted to determine the waste generated and the perception and role of community participation in managing waste, especially household waste in residential areas. In this study, data collection was carried out in one of the housing areas in Bogor City, namely the Pakuan Regency. The collection of daily waste data to measure waste generation and composition is carried out based on the Indonesian National Standard 19-3964-1994 method. This data analysis technique uses a qualitative descriptive analysis with respondents differentiated on the basis of type of house and the number of occupants. This research produces data on waste generation for small, medium, and large house types 286,12 kg/houses/year, 366,57 tons/houses/year, and 523,67 kg/houses//year respectively. The result showed that the total of household waste, the level of participation and the household’s willingness to pay for TPS 3R plan made it possible to implement the TPS 3R program in this residential. Operational cost for TPS 3R can be covered from the retribution annual revenue.

Abstract

Developing new and renewable energy (NRE) is a sustainable solution to the current complexity associated with population growth and environmental problems. Some developed countries have recognized renewable energy development as a substitute for non-renewable energy such as coal, petroleum, and natural gas. Therefore, this study employed the geospatial approach scheme to identify the NRE potential in the Cipunegara watershed. This was achieved using regional research with a spatial approach and considering five locations in the upstream area of the Cipunegara watershed. Data were collected through observation, consultation with experts, and map interpretation, and analyzed using descriptive statistics. The results showed that only location 2 had a significant potential to be used in building a dam to generate electrical energy. This study was based on several aspects such as hydrology, morphology, topography, meteorology, erosion, geology, and land use. The results were derived from empirical data and geospatial modeling, and expected to serve as a significant reference for the central government in developing EBT as the tangible manifestation of the Sustainable Development Goals 2030 program and the implementation of the national research master plan 2017-2045.

Abstract

Jember Regency is the third largest agricultural area in East Java Province. Expansion of built-up and agricultural areas occurred and significantly changed the landscape. Moreover, increasing both types of land cover will increase water consumption. Therefore, there may be changes in the condition of the water balance in the Jember Regency area. This area has three major watersheds: Bedadung, Mayang, and Tanggul. This study evaluated the water balance condition at the three major watersheds in Jember, East Java, Indonesia. The WEAP (Water Evaluation and Planning) model calculated the water balance. Research procedures include (1) inventory of spatial and non-spatial data; (2) setup of the WEAP scheme; (3) Calibration; (4) Validation; and (5) Simulation of water balance model in scenario increasing water demand and land-use change). From 1997 to 2020, the water balance was evaluated using a 10-day interval. The results show that from the November 1st to August 2nd periods, the watershed can supply all demand sites with 100% coverage. However, from August 2nd t to October 3rd periods, the watershed’s ability to supply the water needs decreased. This deficit is due mainly to the uneven rainfall distribution between rainy and dry seasons. Variation in annual rainfall received from 1997 to 2020 also affects the water balance’s surplus and deficit. The fluctuation of land-use change contributed to the surplus and shortage of water balance.

Abstract

Tourism objects in Pacitan Regency are increasingly diverse and attract tourists from within and outside the region to visit. The price of residential land is one aspect that has also changed along with these developments. The phenomenon of changes in land prices also occurred in Watukarung Village. This study aims to analyze changes in the price of residential land and its relation to tourism developments that occurred in Watukarung Village based on the perceptions of the local community. The method used is qualitative with data collection techniques in the form of in-depth interviews. The data from the interviews were processed using data reduction techniques so that a unit of information was obtained which could then be analyzed descriptively qualitatively. The accuracy of the data obtained was tested using a data source triangulation technique that compared the results of one informant with another. The result shows that the development of tourism has attracted foreign tourists to come and buy residential land in Watukarung Village. The price of residential land by the beach was originally around IDR 300,000/m2 increase to IDR 1,000,000 to IDR 1,500,000/m2. Based on the perception of the local community, the significant increase in the price of residential land is closely related to the development of tourism that has taken place in Watukarung Village. However, there are also people who have the perception that rising residential land prices and tourism development have no direct relationship.

Abstract

The increasing population in an area often triggers heightened development, leading to diminished land availability and subsequent land conversion. This transformation, predominantly observed in agricultural and plantation lands, is driven by the need for residential areas. However, continuous land use changes contribute to erosion, a natural process wherein soil is transported, leading to sedimentation and eventual flooding. This study aims to identify critical areas prone to erosion and land degradation. To address this, we used the Universal Soil Loss Equation (USLE) method for erosion prediction, leveraging its simplicity and accuracy. This study focuses on the Mayang watershed in East Java, utilizing a combination of USLE, spectral index modeling, and Geographic Information System (GIS) techniques to estimate soil erosion and land criticality. By integrating methodologies and analyzing data spanning from 2011 to 2021, the study reveals shifts in erosion danger levels and land use patterns. While regions with low erosion remained stable, areas with medium to high erosion declined, yet those with very high erosion exhibited a worrisome increase. Changes in land use, including forest loss and urban expansion, underscore the ecological shifts exacerbating erosion hazards. The study emphasizing the necessity for targeted conservation strategies and comprehensive land management plans to mitigate erosion risks and preserve environmental sustainability.

Abstract

The Citarum River is facing pollution and damage due to domestic and industrial activities. The provincial and national governments have implemented several programs to address the Citarum issue. One key aspect of rehabilitating the Citarum River basin is the increase in environmental awareness among the community. This research aims to examine the influence of the Citarum Harum Program on the formation of Eco-literacy among the communities in Upper Citarum. A survey was conducted with 393 respondents who reside along the banks of the Upper Citarum River, distributed across the 8 sectors of the Citarum Harum Program. The research instruments used include structured questionnaires, documentary studies, and interview guidelines. Data analysis was performed using the Structural Equation Modeling (SEM) technique with SmartPLS software version 3.2.9. The results of the study indicate that Eco-literacy (ECO) has a positive correlation with the handling of existing problems (HP) with a t-value of 1.136. Eco-literacy (ECO) has a negative correlation with the physical, social, and environmental characteristics (CH) with a t-value of -0.486, as well as with the occurrence of problems with a t-value of -0.237. This suggests that the formation of eco-literacy among the communities in Upper Citarum is highly dependent on the efforts undertaken by the task force. However, there is currently no connectivity between the knowledge and attitudes of the community towards actions in the restoration of river pollution and damage.

Abstract

Comprehensive information on seagrass biodiversity indicators, such as species composition, percentage cover, and biomass carbon stock, remains limited across various regions globally. Mapping these indicators using remote sensing images requires extracting maximum information from the input images to achieve effective results. This study aims to map seagrass distribution, percent cover (PC), and aboveground carbon stock (AGC) as biodiversity indicators in the optically shallow waters surrounding Pari Island. We integrate WorldView-2 (WV2) derivatives, field seagrass data, and RF classification and regression algorithms to accomplish this objective. The WV2 image derivatives encompass surface reflectance bands, band ratios, mean and variance co-occurrence texture bands, and principle component bands. These inputs are used individually and collectively for mapping, employing a random forest algorithm trained with field seagrass data. Our results demonstrate that the most accurate benthic habitat map achieves an overall accuracy (OA) of 65.2%, with a user's accuracy of 65.2% and a producer's accuracy of 72.8% for the seagrass-dominated class. Seagrass PC mapping yields a root mean square error (RMSE) of 17.1%, with an average PC of 47.4 ± 9.9%. Seagrass AGC mapping achieves an RMSE of 5.0 g C m-2, with an average AGC range of 6.2 – 29.1 g C m-2, estimating the study area's aboveground biomass carbon stock at 27.9 tons C. Combined inputs produce the most accurate results for all biodiversity indicators, emphasizing the importance of utilizing combined bands from SR band derivatives to maximize information input for training mapping algorithms, instead of using derivative bands individually or as replacements for the initial SR bands.

Abstract

The complexities and consequences of violent crimes require a robust and effective approach to achieve a sustainable reduction of violence in our society. This paper, therefore, presents an avenue to provide the geo-quantitative analysis of violent occurrences in Kaduna State of Nigeria to determine the pragmatic interventionist strategies for managing violent crime incidence among the people of the study area. Geo-quantitative analysis entails transforming numerical data about criminal activities into a map of proportional circles to depict the distribution pattern of criminal activities and using scree plots and factor loading to show higher-order intervention measures for managing violent crimes. Five Local Government Areas (LGAs) with relatively high levels of violent incidence were purposively selected while snowball sampling method was used to administer questionnaires to 384 respondents. From the findings, the spatial distribution of violent crimes revealed that Birni-Gwari and Kachia LGAs accounted for the highest incidence of kidnapping and village raids respectively while Kajuru LGA is known for the highest cases of cattle rustling and armed robbery. The critical interventions in managing violent crimes are reconciliation efforts to restore order and normalcy, negotiation between aggrieved parties, and adoption of a traditional conflict resolution system with a rotated factor matrix of 0.828, 0.581, and 0.544 respectively. Furthermore, the strongest positive correlation exists between good government policies and equity with fairness in representation and establishment of developmental projects (r = 0.524, and p Ë‚ 0.001). Therefore, the study recommended establishing conflict mediation centers across the communities. Similarly, it is essential to have a good governance system that will give people their fair share of national resources and adequate policing of communities that could guarantee the reduction of violent incidents to the barest minimum.
