Abstract

Pemahaman tentang sistem hidrogeologi dan wilayah tangkapan air dari sebuah mata air sangatlah penting. Hal ini untuk membantu pengelolaan yang menjaga kelestariannya. Mataair Beton merupakan salah satu mataair yang memiliki peranan yang sangat penting di wilayah Ponjong, Kabupaten Gunungkidul. Suplai air dari mataair ini digunakan untuk memenuhi kebutuhan air bersih, irigasi persawahan dan perikanan. Penelitian ini bertujuan untuk mengetahui konektivitas dan karakterisasi lorong di sistem hidrogeologi Mataair Beton. Metode yang digunakan adalah tracer test dengan menggunakan fluorescent dyes. Hasil analisis menunjukkan bahwa Ponor Seropan memiliki konektivitas dengan Mataair Beton, dan memiliki karakteristik lorong berupa single conduit. Perkembangan lorong yang lanjut menunjukkan bahwa sistem hidrogeologi di lokasi kajian sangat dipengaruhi oleh imbuhan airtanah dari sistem alogenik yang berhulu di wilayah non-karst dan memiliki kerentanan terhadap pencemaran airtanah yang tinggi.Kata Kunci: Karst, Sungai Alogenik, Kawasan Karst Gunung Sewu, Uji Perunutan, Mataair BetonAn understanding of the hydrogeological system and catchment area of spring is very important. This is to help manage that maintains its sustainability. Beton Resurgence is one of the springs that have a very important role in the Ponjong area, Gunungkidul Regency. Water supply from the spring is used to supply clean water, irrigated rice fields, and fisheries. This study aims to determine the connectivity and characterization of Passage in the Beton hydrogeological system. The method used is a tracer test using fluorescent dyes. The results of the analysis of breaktrough curve indicate that Seropan Sinking Stream has connectivity with Beton resurgence, and has passage characteristics in the form of a single conduit. The further development of the passage shows that the hydrogeological system is strongly influenced by groundwater recharge originating from an allogenic system that originates in non-karst areas and has a high groundwater vulnerability to pollution. Keywords: Karst, Allogenic River, Gunungsewu Karst Area, Tracer Test, Beton Resurgence

Abstract

Allogenic recharge generally contributes to the formation of the main underground river system in a karst area. However, allogenic recharge have a higher susceptibility to contamination than autogenic recharge. This is because recharge from allogenic rivers enters the underground river system without undergoing filtration by soil or rock cavities. This paper discusses changes to ministerial regulations related to karst management that have led to the exclusion of allogenic river areas from the management of allogenic rivers, examines the urgency of managing allogenic rivers, and recommends future management of karst areas from the perspective of water resources management. The change in the Minister of Energy and Mineral Resources (ESDM) regulation regarding karst management has led to a simplification of the scope related to the main tasks and functions of the Ministry of ESDM. This should be followed by making changes to regulations that are higher than the ministerial level regulations so that the management objectives stated in the previous regulation can be covered and there is holistic management of the karst area.

Abstract

Previous research on meandering rivers in Indonesia, precisely in Java, has predominantly focused on alluvial plains, while their presence is also observed in hilly regions with rocky substrates. The study aims to investigate different meandering types in Java and establish regional connections between these types and geological and geomorphological processes. The methodology involves identifying high-resolution remote sensing images and topographic data, followed by analysis based on geological and geomorphological developments. To categorize the rivers, sinuosity ratios are meticulously calculated. The tectonic setting, which influences physiography and geomorphology, is an analytical unit for determining the meandering process. The result reveals that meandering rivers are primarily located in the alluvial plains of northern Java. Meanwhile, meandering rivers in hilly areas are concentrated in structural formations, predominantly in southern and central Java. In alluvial plains, meandering rivers display a regular pattern with higher concentrations of curvature downstream, and their substrates consist of deposits or soil. Conversely, meandering rivers in hilly regions exhibit irregular and winding patterns, randomly distributed from upstream to downstream. These rivers are situated in the physiographic regions of Southern Mountains, Hills in Central Depression, and Kendeng Hills, and their substrates mainly comprise rocks, leading to a more protracted process of curvature transformation. In conclusion, meandering rivers in Java can form not only in alluvial plains but also in hilly areas. Meanders on hilly topography possess higher sinuosity ratios than those on alluvial plains, displaying irregular patterns. Energy minimization alone is not the sole controlling factor; the physical surface conditions also play a significant role, particularly in meanders in hilly areas, resulting in a diverse typology of meanders. Therefore, understanding the formation of meandering rivers in various topographic regions can serve as a basis for policymaking, particularly in flood mitigation and riverbank erosion management.

Abstract

COVID-19 pandemic was reported to modify people’s behaviour in using public spaces and accessing services. This fact has become a critical input related to future city development strategies, space arrangements, and the implementation of smart city. Therefore, this study aims to 1) Identify efforts in several cities during COVID-19 pandemic, specifically concerning the use of public spaces and services, and 2) Compile the outlines of future urban planning strategies after the pandemic. The aspects related to the use of Information and Communication Technology (ICT), space arrangement, and urban environment are discussed. The analysis is based on case studies in four capital cities, namely Jakarta, Paris, Bucharest, and Canberra. Furthermore, field observations and in-depth interviews are used to emphasize changes in the function and use of public spaces and services during and after the pandemic. The result shows that differences and common elements configure the transformations of urban spaces since changes in the use of public spaces are closely connected to efforts to combat the pandemic. Meanwhile, in public services, changes are associated with the increasing use of ICT and Internet of Things (IoT). In the future, cities need to show their visions according to the local conditions supporting better spatial arrangement and management of urban environment due to ICT and IoT prominence.

Abstract

A traditional agroforestry of West Timor, namely Mamar, produces important ecosystem services to the people of this arid region, however, its management tends to change, thereby disrupting its sustainability. This study aims to assess the sustainability of Mamar agroforestry by analyzing the livelihood assests of the community, the biophysical land performance of the soil, and the value of ecosystem services. Furthermore, data, on perception and livelihood assets; the level of soil damage, the importance value index, and diversity index, the value of ecosystem services based on the opinion of experts and community leaders, as well as change in land use were collected in five villages in Kupang district using surveys with a qualitative and quantitative approach. The results showed a change of perspective in Mamar's management; the decrease in the important value index of cultural crops, the diversity index is classified as declining, there is soil damage in several parameters, and the value of ecosystem services does not focus on cultural services. Considering this result, there is a socio-ecological trade-off that reduces support for the sustainability of  Mamar as traditional agroforestry that emphasizes socio-cultural functions.

Abstract

The livelihoods of farmers in developing countries are often associated with the existence of forests, especially agroforestry. The dynamics of agroforestry and livelihoods could not be separated from the political context and developments in Indonesia. In this paper, the dynamics of Sustainable Livelihood Assets (SLA) owned by smallholder farmers are explored using three political sequences, namely the New Order Era, the Reform Era, and the Post-Reform Era. The result showed that the development of agroforestry in Gunungkidul had been primarily influenced by political initiatives that have a connection with vegetation coverage, livelihood assets, and species composition in the systems. The livelihoods possessed by farmers have been relatively sustainable during the past five decades; only a slight change could be observed in the ownership of capital. The political initiatives have been an enabling environment for agroforestry development that support sustainable livelihoods. The study recommends that the socio-political culture needs to consider the traditional agroforestry system in order to sustain the livelihoods of the people.

Abstract

In the challenging realm of earthquake prediction, the reliability of forecasting systems has remained a persistent obstacle. This study focuses on earthquake magnitude prediction in Indonesia, leveraging supervised machine learning techniques and cloud radon data. We present an analysis of the tele-monitoring system, data collection methods, and the application of regression-based machine learning algorithms. Utilizing a comprehensive dataset spanning 30 training instances and 105 test instances, the study evaluates multiple metrics to ascertain the efficacy of the prediction models. Our findings reveal that the linear regression approach yields the best earthquake magnitude prediction method, with the lowest values across multiple evaluation metrics: standard deviation 0.40, mean absolute error (MAE) 0.30, mean absolute percentage error (MAPE) 6%, root mean square error (RMSE) 0.52, mean squared error (MSE) 0.28, symmetric mean absolute percentage error (SMAPE) 0.06, and conformal normalized mean absolute percentage error (cnSMAPE) 0.97. Additionally, we discuss the implications of the research results and the potential applications in enhancing existing earthquake prediction methodologies.
