Abstract

Satellite gravity provides a new alternative in geological exploration with several advantages, such as low operational cost and large covering area. GGMplus satellite gravity data provide better accuracy for several applications such as lithology or fault identification. Satellite gravity provides a new alternative in geological exploration with several advantages, such as lower costs, broader area coverage, and easily accessible data. Mount Tampomas is one of the areas that has geothermal prospects and a mountain area that has many types of rock formations and faults. This research has been conducted using GGMplus satellite gravity data in the Mount Tampomas area to obtain the second vertical derivative (SVD) and identify the fault distribution in the area. The GGMplus Gravity Acceleration data was corrected and filtered to obtain SVD structures in the area. The structure in this area is dominantly trending northwest-southeast and west-east. The area around Mount Tampomas forms a structure in the form of a caldera. In addition, there are also structures trending north-south at coordinates 81500-82000 E. Some of these structures were overlaid with a geological map to see the suitability of the processed data with the geological conditions that have been studied. The comparison is done by overlaying the structure of the interpretation results and the contour of the value 0 from the Second Vertical Derivative (SVD) data so that we get four fault structures that correlate with the geological map, three calderas, and one lineament that correlates with the lineament map.

Abstract

The development of shallow groundwater-based irrigation has been carried out by many farmers to meet water needs in sub-optimal land in Pekon Ambarawa Timur. Several wells have failed to obtain groundwater and others have decreased discharge which makes pumping costs uneconomic. Measurements across two 2D geoelectric trajectories have been made to obtain the presence of shallow aquifers. Data acquisition using the ARES instrument, Wenner Schlumberger configuration with a track length of 200 m and space between electrodes of 5 m. The results of sampling in two passes, the presence of aquifers formed lenses in the dominant environment of clay material at a depth of 2-30 m. In addition to being influenced by clay materials that are low permeable, there are also melts and intrusions forming some igneous rocks. To meet the purpose of irrigation sources, the manufacture of wells is placed in the presence of aquifer lenses. In addition to production, it can also be developed as an injection well-capturing puddles of rainwater filling shallow aquifers.

Abstract

Graphical Abstract   Highlight Research 1. Develops an ecosystem-based model to enhance SME fish processing performance. 2. Applies the Delphi method with multi-sectoral expert consensus. 3. Identifies ten strategic priorities, with certification as the key enabler. 4. Provides a systemic framework aligning institutions, markets, and regulation to improve sustainability and innovation in Indonesia’s fish processing sector.   Abstract This study examines how institutional, market, technological, regulatory, and human capital issues impact the performance of Small and Medium Enterprise Fish Processing Units (SME-FPUs), specifically in Indonesia. The study's goal is to provide an ecosystem-based model for improving the performance of SME-FPUs by combining essential institutional, market, and technology components. Thirteen multi-sectoral experts from government, business, academia, and certification organizations were consulted for the study using the Delphi technique. Strategic variables for model building were identified and prioritized using the expert's insights. Ten strategic priorities were determined by the analysis. These priorities included business licensing facilitation, raw material supply assurance, cold chain infrastructure development, managerial and technical competency capacity building, quality certification promotion, and consumer awareness campaigns. These goals were incorporated into a systemic model that places certification as the primary facilitator in a framework that is favorable to consumers, organizations, and regulations. Study adds to the theoretical conversation by presenting a comprehensive and adaptive ecosystem model that goes beyond reductionist or linear frameworks. In practice, it provides a practical blueprint for governments, development agencies, and industry players to create coherent and sustainable solutions. More study is needed to experimentally evaluate the model's applicability across various geographic settings and sectors of the blue economy.
