Abstract

This study examines the condition of flyrock and safe blasting distance at the jobsite of PT Unggul Dinamika Utama-PT Indexim Coalindo in East Kutai, East Kalimantan. The study was conducted at Pit Tempudo 6 by collecting blasting geometry data and actual flyrock points using GPS as many as 30. The research method used was the actual calculation of flyrock throwing distance using Pythagoras and the predicted calculation of flyrock throwing distance using the theory of Richard and Moore and Ebrahim Ghasemi which was then carried out a technical study of flyrock and minimum safe blasting distance. The processing results showed the use of an average blasting geometry with a burden value of 7.86m, spacing of 8.96m, stemming of 3.64m, blast hole depth of 7.05m, powder column of 81.64kg with the furthest actual flyrock distance of 90.3m. The influence of blasting geometry parameters obtained a burden value of 0.01%, spacing of 0.86%, Stemming of 18.09%, blast hole depth of 6.38%, powder column of 2.21%. Stemming has a high influence on flyrock, with a percentage of 18.09%. Additional factors such as inadequate site preparation and insufficiently dense stemming also contribute to flyrock. Theoretical predictions after the calculated data were transformed showed that the Richard and Moore cratering factor method had the closest results, at 24%, compared to Ebrahim Ghasemi's 29%. Based on technical studies, the recommended safe radius is 181 m for heavy equipment, while for humans it remains at 500 m.

Abstract

The significant tourism potential at Takari Beach must be managed well to attract tourists, including providing the crab apartment tourist attraction. Crab fattening activities using an apartment system at tourist locations can develop the mud crab (Scylla serrata) species. This is expected to increase visitor interest in educational tourism from the Takari Beach tourist destination. PKM activities aim to develop tourist attractions through the apartment system of fattening mangrove crabs (Scylla serrata) by KTH HKM Takari Bangka Belitung. This activity was carried out from May to November 2023 at Takari Beach, Rebo Village, Sungailiat District, Bangka Regency, Bangka Belitung. The method is carried out in a participatory manner that prioritizes the role and participation of the HKM Takari Manager as a supporter in the apartment system of mangrove crab fattening. The results show that the KTH HKM Takari Manager was given a business permit for forest utilization covering 59 Ha. Adding a tourist attraction in the form of mangrove crab (Scylla serrata) apartments on Takari Beach is an innovation the management can develop. Land preparation and construction of crab apartments was carried out over 3 months with 54 apartment boxes. The procurement of young mud crabs is managed by HKM Takari Management and purchased from fishermen who catch mud crabs, which are then fattened in the crab apartment. Measuring the length and weight of mud crabs, water quality, and substrate is very helpful in analyzing the growth and survival of mangrove crabs sustainably. Innovation in tourist attractions with apartment systems fattening mangrove crabs gives new enthusiasm to managers. The mangrove crab apartment tourist attraction is expected to support sustainable tourism management.

Abstract

Geoelectric measurements have been carried out using multichannel ResistivityMeter (Geores) tools with Wenner, Wenner-Schlumberger, and Dipole-dipole Configuration approaches on the influence of materials arranged in a laboratory-scale measuring tub design with dimensions of 194x184x80 cm. The measured method is the variation in resistivity value against each trajectory of the material. The method used is the variation of resistivity values for each path of the material that has been arranged in a laboratory scale measuring design. Geoelectric measurements were carried out on 7 lines (5 line in the West-East direction and 2 line in the North-South direction). The spacing between the electrodes of each line is 10 cm with 16 electrodes in one line so that each line has a length of 160 cm or 1.6 m which corresponds to the length and width dimensions of a laboratory scale measuring design. The electrode arrangement parameters are constant with respect to changes in the configuration selected from the geores parameters during geoelectric measurements. The measurement results showed that the identified depth reached 31.2 cm. The low resistivity value category has an interval of 374-4,397 ohm.meters at a depth of 0-12.5 cm, which is the influence of building sand material containing water and soil, while the depth interval is 12.5 - 31.2 cm ohm.meters (material category that is influenced by 2 iron rods, tin tailings sand, granite, gravel) with resistivity values ranging from 12,378–67,498 ohm.meters. From experiments on the influence of the resistivity values of the three Wenner, Wenner-Schlumberger, and Dipole-dipole configurations, it was obtained that the smallest absolute error resistivity value in the Wenner configuration was 5.01% against the overall average absolute error resistivity value of 10.16%.

Abstract

Abstract The coastal waters surrounding Pasir Padi Beach, located on the eastern side of Pangkalpinang, constitute a transitional zone between terrestrial and marine environments that is highly susceptible to sedimentation pressure, particularly from tin mining activities. This study aims to map and analyze the distribution and concentration of Total Suspended Solids (TSS) in the coastal waters of Pasir Padi Beach and its surrounding areas. The monitoring was carried out using a Google Earth Engine–based platform over a four year period (2022–2025) utilizing Sentinel 2A satellite imagery. The analysis employed a modified version of the Parwati method to estimate TSS. The findings revealed TSS concentrations ranging from 60–80 mg/L and >80 mg/L, represented by red and orange colors, which were predominantly distributed along the coastline. Meanwhile, the green areas, indicating TSS concentrations of 20–30 mg/L, functioned as a transitional or coastal belt before reaching the offshore waters characterized by low TSS values of 0–20 mg/L, depicted in blue. These results demonstrate that regions located near river mouths and tin mining zones are more prone to high sedimentation intensity, with the highest accumulation occurring toward offshore areas. Consequently, periodic monitoring is essential to mitigate potential environmental impacts such as river mouth siltation and disruptions to coastal dynamics and coastal activities.
