Abstract

Gununganyar Reservoir in Tuban Regency is one of the reservoirs used as a source of livelihood for the local community. However, further development and utilization of Gununganyar Reservoir have yet to be undertaken. The development of a small-scale floating Photovoltaic Solar Power Plant (floating solar panels) at Gununganyar Reservoir, aimed at providing an alternative and renewable energy source for operating raw water pumps and for supporting the Gununganyar Nature Tourism (WAG) initiative, constitutes an innovative and strategic effort to enhance energy efficiency and environmental sustainability in rural areas. This study focuses on the design and performance assessment of a floating solar panel system constructed with processed bamboo as an alternative floating material replacing HDPE, while integrating local wisdom and environmental conservation principles to minimize the reservoir’s carbon footprint. The methodology employs a simple quantitative approach combined with a literature review of relevant studies. Based on the analysis, the design of this small-scale floating solar panel system utilizes a 170 Wp off-grid solar module mounted at a tilt angle of approximately 7,1°, capable of generating a peak power output exceeding 2,962 kWp and supported by a battery capacity of 328,33 Ah. The implementation of these floating solar panels is expected to serve as a model for reservoir development by promoting energy self-sufficiency, stimulating local economic growth, and contributing to the achievement of net zero emissions by 2060.

Abstract

The increasing demand for housing in tropical regions requires building materials that are fast to apply, environmentally friendly, and resilient to extreme climate conditions as well as disaster risks. Conventional interlocking bricks are often chosen for their ease of construction, yet they still face challenges such as moisture and early cracking. This study proposes the innovation of the Hybrid Living Green Brick, a combination of lightweight bricks made from rice husk ash and fly ash waste (FRCB) with a biological layer of cyanobacteria. FRCB improves compressive strength by approximately 30% with the addition of 5% rice husk ash, achieving 65 kg/cm², thereby meeting Class 50 requirements (≥50 kg/cm²) according to SNI-15-2094-2000. The incorporation of 3% cyanobacteria provides an additional though not significant strength improvement, while still within the Class 50 category. It also reduces brick weight by 4.3%, with further optimization potential through cyanobacteria integration, and lowers carbon emissions from the firing process. Cyanobacteria induce the formation of CaCO₃ layers that seal pores, reduce water absorption by an average of 10%, and provide self-healing properties for microcracks. Preliminary observations indicate that FRCB offers stable mechanical performance, while biological activity was observed on the 7th day with the formation of pale-white mineral layers continuing until the 28th day. This hybrid innovation shows potential to support sustainable and disaster-resilient tropical construction by combining the mechanical strength of waste-based materials with the biological durability of cyanobacteria against extreme climates. Despite challenges related to moisture control and production standardization, the Hybrid Living Green Brick concept opens new pathways for developing environmentally friendly construction materials that are more adaptive to disaster-prone tropical conditions.

Abstract

This study investigates the effect of roof tile waste used as a partial replacement for fine aggregate on the fresh and hardened properties of concrete, with the aim of promoting more sustainable and environmentally friendly construction materials. The research employed an experimental laboratory method with quantitative analysis. Roof tile waste was incorporated into concrete mixtures at substitution levels of 0%, 5%, 10%, 15%, and 20% by weight of fine aggregate. The workability of fresh concrete was evaluated using slump tests in accordance with SNI 1972:2011, while compressive strength tests were conducted on cylindrical specimens after 28 days of curing based on SNI 1974:2011 standards. The results indicate that increasing the proportion of roof tile waste reduced concrete workability, as shown by a decrease in slump values from 10 cm in the control mix to 8 cm at the 20% replacement level. Compressive strength also exhibited a declining trend, decreasing from 14.63 MPa to 11.90 MPa at the highest substitution, representing an approximate reduction of 18.7%. Nevertheless, concrete containing 5% roof tile waste achieved a compressive strength of 14.32 MPa, which is comparable to normal concrete. These findings suggest that roof tile waste can be utilized as a partial fine aggregate replacement at limited levels. A 5% substitution was identified as the optimal proportion to maintain acceptable workability and strength while supporting sustainable concrete development.

Abstract

The stability of disposal slopes is a critical aspect of open-pit mining operations because it directly affects operational safety and the continuity of overburden dumping activities. Disposal areas composed of overburden materials generally exhibit heterogeneous characteristics, particularly when soft materials such as mud are present, which can significantly reduce slope stability. Therefore, a comprehensive slope stability evaluation is required prior to further disposal development. This study aims to assess the stability condition of a disposal slope under initial conditions, evaluate the influence of material conditions, and analyze the effectiveness of counterweight application in improving both the safety factor and disposal capacity. The research methodology involved the collection of primary and secondary data, including slope geometry, lithological conditions, and the physical and mechanical properties of disposal materials obtained from laboratory testing and company technical data. Slope stability analysis was performed using the limit equilibrium method with the assistance of geotechnical software, taking into account groundwater conditions and operational loading. The analysis results indicate that the initial disposal condition yielded a safety factor of 0.718, indicating an unstable slope condition. After simulating the removal of mud material, the safety factor increased to 0.907 but remained below acceptable stability criteria. The application of a counterweight significantly improved slope stability, resulting in a safety factor of 1.498. Further optimization through slope geometry redesign produced a final safety factor of 1.101, which satisfies the requirements stipulated in KEPMEN ESDM No. 1827 K/30/MEM/2018. Additionally, the redesign increased the disposal capacity from 119,507,864.23 LCM to 119,682,378.22 LCM, representing an increase of 174,513.99 LCM. These results demonstrate that counterweight application combined with geometric optimization is effective in enhancing both slope stability and disposal capacity.

Abstract

This study aims to analyze the characteristics of the soil at PIT North with two highwall and lowwall locations at PT Karya Putra Borneo, Kutai Kartanegara Regency, East Kalimantan Province. The research method was carried out by collecting primary data from the results of field tests using the sondir method with the Cone Penetration Test(CPT) tool and laboratory tests using physical properties, specific gravity, grain size, soil consistency, and consolidation tests, as well as secondary data from the results of literature studies. The parameters analyzed for soil characteristics include the sondir cone resistance (qc) value, grain size fraction distribution, soil plasticity index, and the rate of land subsidence through consolidation. The results showed that at PIT North the highwall area had a qc value of 5.6 Mpa, Fr 0.2%, IP 8.06%, Cc 1, a large rate of land subsidence of 3.3 mm with a settlement period of 4 years. In the lowwall area with a qc value of 10.31 Mpa, Fr 0.16%, IP 6.39%, Cc 0.535, the rate of settlement was 4.4 mm with a settlement period of 3 years. From these results, it is concluded that the soil at the highwall and lowwall locations has different compressibility, seeing the different soil Cc values and the soil plasticity index that affect the compressibility level of the soil and the value of the land settlement rate.
