Abstract

Coal is used as fuel for the Air Anyir Steam Power Plant (PLTU) on Bangka Island. The combustion waste in the form of fly ash and bottom ash has not been utilized optimally as an alternative material for road construction. Therefore, this study aims to analyze the potential use of bottom ash as a filler in the HRS-WC mixture. The HRS-WC mixture uses two variations of filler, namely cement and bottom ash. The variation of asphalt content used is 6.5%, 7%. 7.5%, 8%, and 8.5%. The results showed that the use of bottom ash as a filler resulted in a KAO value of 7.95% and the stability value of the mixture was greater than using cement filler. So, bottom ash has potential as an alternative filler in asphalt mixtures. ABSTRAK Batu bara digunakan sebagai bahan bakar untuk Pembangkit Listrik Tenaga Uap (PLTU) Air Anyir di Pulau Bangka. Limbah hasil pembakarannya berupa fly ash dan bottom ash belum dimanfaatkan secara maksimal sebagai bahan alternatif konstruksi jalan.

This study aims to analyze the base sectors that can support economic growth and examine the potential of the mining and quarrying sector in supporting economic development in the region. The data used in this study is secondary data obtained from various related agencies, one of which is the Central Statistics Agency (BPS). The data analyzed includes the Gross Regional Domestic Product (GDP) of Eastern Seram Regency and Maluku Province based on constant prices by business field in the 2011-2020 period. This study uses Location Quotient (LQ) and shift-share analysis methods to identify the base sector and analyze the dynamics of economic growth. The results of the analysis show that the base sectors in this area include the fisheries, forestry, and agriculture sectors with an LQ value of 1.06; mining and quarrying sector with an LQ value of 11.37; real estate services with an LQ value of 1.13; and health services and social activities with an LQ value of 1.07. However, the growth of the value of GDP in the mining sector during the 2011-2020 period experienced a significant decrease, namely -6,323.94 million rupiah. Other growth indicators, namely the Proportional Growth Contribution (KPP) of -0.22 and the Regional Growth Contribution (KPPW) of -0.14, also show that the mining and quarrying sector is relatively slow in growth, although it remains competitive at the regional level. The decline in the value of KPP and KPPW with a negative sign (-) in the mining and quarrying sector confirms that this sector is experiencing suboptimal growth. Although its competitiveness is relatively still there, this persistent decline indicates the need for more attention to improving efficiency and innovation within the sector. This is important so that the mining and quarrying sector can contribute more to improving the regional economy in a sustainable manner. To support the development of this sector, strategic policies, investment in technology, and synergy between the government and industry players are needed to overcome existing challenges

Abstract

The effectiveness of groundwater wells in tectonically active regions remains insufficiently understood due to the lack of integrative hydrogeological evaluations. This study aims to characterize the hydraulic performance of five groundwater wells in Biromaru District, Sigi Regency, an area affected by the 2018 Central Sulawesi earthquake. A combination of the Neuman method and the Hantush-Bierschenk approach was employed to evaluate key aquifer parameters, including transmissivity, storativity, specific yield, and well loss coefficients. Step drawdown tests and time-drawdown data were analyzed to determine aquifer responses under controlled pumping conditions. The results show a clear variation in transmissivity and storativity among wells, indicating heterogeneous subsurface characteristics possibly influenced by post-seismic compaction. Wells 1 and 3 demonstrated high transmissivity and efficiency, supported by C values below 0.5, signifying well integrity and optimal construction. Conversely, well 2 exhibited low hydraulic performance, suggesting lithological constraints or structural deficiencies. The combination of analytical methods provided a robust framework for interpreting aquifer-well interactions in a post-disturbance setting. This study contributes to a deeper understanding of groundwater behavior in seismically disturbed regions and emphasizes the importance of incorporating multi-method approaches in hydrogeological assessments. The findings can serve as a reference for groundwater resource planning, well rehabilitation, and adaptive water management in vulnerable areas like Sigi Regency.
