Abstract

Kesadahan air di dalam tanah dipengaruhi oleh kondisi geologi lokasi air tanah. Kondisi geologi yang banyak mengandung Ca dan Mg akan menyebabkan tingginya kesadahan air yang dapat menyebabkan masalah lingkungan dan kesehatan. Penelitian ini bertujuan untuk menganalisis tingkat kesadahan total, kadar kalsium, dan kadar magnesium dalam air sumur beserta pola distribusi spasialnya. Penelitian dilakukan pada 5 sumur di Kelurahan Kota Uneng Kabupaten Sikka pada bulan September 2024. Analisis tingkat kesadahan total, kadar kalsium, dan kadar magnesium dilakukan menggunakan metode kompleksometri. Sedangkan analisis pola distribusi parameter dilakukan dengan menggunakan sofware surfer 13. Hasil penelitian menunjukan bahwa berdasarkan konsentrasi kesadahan total (675 – 1.212,5 mg/L CaCO3), kadar kalsium (80 – 230 mg/L), dan kadar magnesium (115 – 154,91 mg/L) dalam 5 sumur di Kelurahan Kota Uneng Kabupaten Sikka tidak memenuhi standar baku mutu untuk keperluan higienis dan sanitasi menurut PerMenKes No.32 Tahun 2017 dan standar air minum menurut WHO. Adapun tingkat penyebaran parameter dipengaruhi oleh jenis batuan, kemiringan, dan arah aliran air tanah. Semakin rendah suatu daerah maka semakin tinggi nilai kesadahan total, kadar kalsium dan kadar magnesium.

Abstract

The Problem-Based Learning (PBL) model is a teaching paradigm that facilitates the development of critical thinking skills. Local wisdom refers to a way of life and knowledge manifested in activities commonly practiced by the wider community in a particular region. One example of local wisdom can be traditional musical instruments, which can be incorporated into the learning model. Combining the PBL learning model with local wisdom can help students who struggle to understand conceptual materials, particularly in science education. Integrating local wisdom into science learning can enhance students' understanding. This study aims to improve students' learning outcomes using PBL-based learning grounded in local wisdom on physics topics such as vibrations, waves, and sound for eighth-grade students at SMP Reformasi Plus. The research method used in this study is The experimental method with research subjects consisted of 38 eighth-grade students divided into two classes: VIII-A as the experimental class and VIII-B as the control class. The learning outcomes from the implementation of PBL learning based on local wisdom showed that the N-Gain pretest score for the experimental class was 0.53 and for the control class was 0.49, which falls into the moderate category. Meanwhile, the posttest score for the experimental class was 0.82 and for the control class was 0.67, which falls into the high category. These results indicate that there is an effect of applying the PBL learning model based on local wisdom on improving students' learning outcomes.

Abstract

The use of radiation on plants has varying effects depending on the type of radiation and dose given. This research aims to provide insight into the potential and effects of using radiation in plant breeding and its impact on the physiological and morphological characteristics of plants. This study examines various previous research on the application of radiation rays to horticultural plants, food plants and ornamental plants. The radiation used includes gamma rays, X-rays, sunlight and corona glow discharge plasma. The research results show that radiation can increase genetic diversity and influence plant growth characteristics such as plant height, number of leaves, and chlorophyll content. The right dose of radiation can produce superior varieties with desired characteristics. However, doses that are too high can reduce the survival rate and regeneration capacity of plants.

Abstract

Leachate pollution is a common environmental issue in areas with open waste disposal activities, particularly along riverbanks. Kali Kampung Bima in Kefamenanu City is characterized by domestic waste accumulation that has the potential to generate leachate and contaminate the surrounding environment. This study aims to identify variations in natural subsurface potential values and to determine the migration pattern and flow direction of leachate in the waste accumulation zone of Kali Kampung Bima using the Self Potential (SP) method, a passive geophysical technique that measures natural electrical potential differences in the subsurface. Data acquisition was conducted using the fixed-base technique along two parallel survey lines, accompanied by daily and loop corrections to ensure data stability. The results show potential values ranging from positive to negative. Significant negative anomalies on line P (–15.97 to –17.36 mV) indicate electrokinetic processes associated with leachate migration toward the river channel, whereas line Q exhibits smaller and relatively homogeneous potential values, suggesting lower contamination intensity. The isopotential contour map reveals a leachate migration pattern from the waste accumulation area toward surface water flow. These findings demonstrate that the Self Potential method is effective for identifying negative anomalies related to leachate distribution and flow direction, and it provides a scientific basis for environmental pollution mitigation and sustainable waste management.

Abstract

The increasing national energy demand necessitates the utilization of renewable resources, particularly geothermal energy, which holds significant potential in Indonesia. This research aims to identify potential geothermal manifestation pathways in the Maronge area, Sumbawa (NTB), characterized by surface features (hot springs, fumaroles) with temperatures ranging from 35-43°C. The methodology employed is the gravity method based on GGMPlus satellite data to map subsurface rock density variations. The gravity data processing includes calculating the Complete Bouguer Anomaly (CBA), separating the CBA into regional and residual anomalies using the upward continuation filter, and conducting further analysis using the First Horizontal Derivative (FHD) and Second Vertical Derivative (SVD) technique. The results indicate a negative anomaly in the central area of the study, which is strongly suspected to signify a fault zone or low-density hydrothermal alteration zone. This contact zone serves as a conduit for hot fluids, explaining the emergence of the surface manifestations as an upflow zone. The results of this study can provide additional information for the government in formulating policies for managing the Maronge hot spring potential.

Abstract

The quality of biomass briquettes is largely determined by the type of raw material and the manufacturing process, especially in efforts to develop waste-based alternative fuels. This research analyzes the effect of the combination of coconut shells with cassava skins and corn husks on the physical properties and burning rate of briquettes using tapioca flour adhesive. Test results show that variations in biomass produce significantly different combustion characteristics. Cassava husk–coconut shell based briquettes showed a higher combustion rate (0.24 g/minute), while corn husk–coconut shell briquettes produced more stable combustion with a lower rate (0.17 g/minute). Even though the water content of the two briquettes is still within acceptable limits, the high ash content (>25%) is the main limiting factor because it does not meet the SNI 01-6235-2000 standard and has the potential to reduce energy efficiency. These findings confirm that the selection of biomass type and control of the carbonization process play a crucial role in determining the performance of briquettes. Optimizing production parameters is needed so that agricultural waste-based biomass briquettes can be developed as an alternative fuel that meets national quality standards and supports a sustainable energy transition.

Abstract

The increasing urbanization, natural activities, anthropogenic activities, and tourism in springs in Kota Soe District can potentially lead to the entry of contaminants that can decrease water quality. Therefore, monitoring water quality in springs is currently crucial to ensure the sustainability of water resources. This study aims to determine the concentration of physical and chemical parameters and water quality in the Oebesa, Oebesi, and Oenasi springs in Kota Soe District. Water quality was determined by measured physical and chemical parameters, compared the measurement results with water quality standards, and analysis using the water pollution index method. The research indicate that the temperature, pH, TDS, TSS, and BOD at the three springs meet the Class I water quality standards stipulated by Government Regulation Number 22 of 2021 concerning the Implementation of Environmental Protection and Management for the Water Category. However, the Dissolved Oxygen (DO) values ??of the three springs are relatively low (<6 mg/L) and do not meet these established standards. The pollution index values ??for the Oebesa, Oebesi, and Oenasi springs were 0.456, 0.530, and 0.537, which indicated that the three springs are categorized as being in good condition. This study show that the springs in Kota Soe District remain suitable for use as water sources, however management efforts are required to improved Dissolved Oxygen concentrations.

Abstract

Electrical Resistivity Tomography (ERT) is a geophysical method used to image subsurface structures based on the distribution of material resistivity by injecting electrical current and measuring the resulting potential at the surface. Although widely applied in subsurface exploration, the use of ERT in academic environments is still limited due to the high cost of commercial equipment. Therefore, this study aims to design and develop a laboratory-scale prototype of a subsurface imaging system based on the ERT method as an educational and practical learning tool. The research employed a Research and Development (R&D) method combined with an experimental approach, including the stages of design, fabrication, testing, and calibration of the prototype. Experimental measurements were conducted on homogeneous soil media and soil media with artificial anomalies using Wenner and Wenner–Schlumberger configurations. The acquired data were processed using RES2DINV software to produce two-dimensional subsurface images. The results indicate that the developed prototype is capable of detecting resistivity anomalies effectively, although relatively high inversion errors were observed due to laboratory-scale limitations. Overall, the proposed ERT prototype is suitable as a supporting tool for geoelectrical learning and subsurface exploration practicum.
