Abstract

Penta Helix is used in public policy, but in some instances, the Penta Helix can be used as a standard for implementing restoration activities. The involvement of the Penta Helix Plus actor is vital to oversee mining activities and, at the same time, make restoration activities successful in mining.  This research method uses a mixed method, namely combining qualitative data in the form of interviews, documentation, and observations with quantitative data in the form of questionnaires, then conclusions are drawn. This research shows that the Penta Helix Plus is an alternative that involves many parties and becomes an ideal new pattern. Hypothesis testing was obtained at 2p = 0.90 in the rejection area of Ho. In addition, the role of Penta Helix Plus shows that entrepreneurs are much more dominant, with 29%, which shows the restoration of the PT. HMM is based on a high level of personal awareness. In addition, environmental sensitivity that must be returned to its original state is also the reason for this restoration. This study concludes that the median test results show the synergy between the Penta helix plus actors in the restoration activities of excavation C in Pasuruan. Penta Helix Plus is an offer for a new formulation as well as public participation in synergy in controlling exploitation activities and expecting restoration activities to be carried out. The involvement of the Penta Helix Plus cannot be separated from the elements of communication and coordination, which are the most critical synergy indicators. Key Words: Mining, Penta helix plus, reclamation.

Abstract

As a country in the tropics, Indonesia experiences drought almost yearly. However, prevention is still very slow, particularly in East Java Province, making it a prolonged problem. Meteorological drought is closely related to climate anomalies or weather instability that result in changes in rainfall patterns. Meteorological drought is analyzed using the EDI (Effective Drought Index) method. As a form of meteorological drought disaster mitigation, good and evenly distributed rainfall data is needed. Satellite technology such as CHIRPS can complement the uneven distribution of rain stations and areas difficult to reach by meteorological stations. The analysis shows that the worst drought occurred in 2005 with a minimum index value of -2.41, followed by 2007 (-1.94), 2012 (-1.55), 2017 (-1.62), and 2019 (-1.50). Based on the trend of drought events that occur every 2 to 5 years. This study’s results indicate that satellite rainfall data can help provide a more complete picture of drought conditions in the Slahung Sub watershed. With this study, an early warning system for drought mitigation is expected to be developed, and more effective measures can be planned to deal with future drought disasters in Ponorogo Regency.

Abstract

Ministry of Forestry has designated Kreo Sub-watershed, part of Garang Watershed, a critical area due to high erosion rates contributing to flooding in Semarang. Rapid land use changes accelerate environmental degradation, increasing erosion and sedimentation risks. This study measures erosion and sedimentation rates in Kreo Sub-watershed using SWAT (Soil and Water Assessment Tool), determines Erosion Hazard Index, and proposes erosion control solutions based on Land Rehabilitation and Soil Conservation Analysis (ARLKT) with vegetative conservation. ARLKT approach includes simulating new land use scenarios to assess their impact on erosion reduction. To ensure SWAT modelling accurately represents field conditions and not overestimate, allowing conservation recommendations based on ARLKT applied appropriately, a field-based sedimentation analysis also conducted. The study utilizes rainfall, soil type, slope, and land use data in 2019 and 2024 from satellite imagery and validated using a confusion matrix. Results indicate a shift in Erosion Hazard Index from predominantly ‘Moderate’ in 2019 to ‘High’ in 2024, underscoring urgent need for sustainable watershed management. By integrating remote sensing, field validation, and hydrological modeling, this study offers a precise, data-driven approach to erosion control. The findings serve critical reference for policymakers in developing effective conservation strategies to enhance watershed resilience.

Abstract

Parung River drainage sub system is located in Kediri City. At the peak of the rainy season inundation often occurs on hos cokroaminoto road, kilisuci road and terusan kaliombo road, the cause is reduced water catchment areas and drainage capacity can’t accommodate discharge, so it is necessary to handle water conservation-based inundation. The analysis conducted was modelling the sub-system using the Storm Water Management Model (SWMM) version 5.1 with a 5-year return period. Rainfall calculation used 10 years of daily rain data (2012-2021) from 3 rain stations (Mrican, UPT Kediri, and Pesantren). The 5-year return period results is 129.4 mm/day, then the intensity of rain is calculated using the Mononobe formula. To calibrate the model, comparing observation discharge with simulated discharge of SWMM resulted the Nash-Sutcliffe efficiency number is 0.62 and the correlation R is 0.91. The results of the existing simulation show that Parung River drainage sub-system was not able to accommodate the 5-year return period discharge, impacting 27 overflow points. Water conservation based handling with the application of infiltration wells and rainwater harvesting can reduce discharge on land ranging from 51.58% to 90.91%, while in the channel successfully reduces discharge from 1.73% to 90.40%.
