Abstract

The rice fields in Bonto Rannu Village, Kajang District, Bulukumba Regency are dominated by rainfed rice fields. This species has limitations in the dry season because irrigation/agricultural irrigation is completely dependent on rainwater. Therefore, it is necessary to identify alternative irrigation sources for the sustainability of farmers' farming activities in Bonto Rannu Village. This study aims to analyze the quantity of groundwater wells by testing in the form of a pump test (pumping test) with the step draw down method. The optimum discharge (Qopt) of well 1 is 0.01876 m3/s or 67.53 m3/hour with an optimum Sw of 2.891 m. This shows that groundwater in well 1 can be pumped at 67.53 m3/hour with a decrease in water level of 2.891 m with the pump condition still technically safe. As for well 2, the optimum discharge (Qopt) is 0.00318 m3/s or 11.45 m3/hour with an optimum Sw of 2.100 m. These data indicate that there are limited groundwater reserves.

Abstract

Springs are a problem in areas where geographic conditions are predominantly hot with low annual rainfall. Water is one of the basic needs for all living things on Earth, both plants, animals and especially humans. If there is a scarcity of spring sources, it is certain that daily activities are very disturbed. Scarcity of springs as happened in Jenetallasa Village greatly influences community activities in the Village. Prolonged drought results in increasingly severe water scarcity that occurs. Based on this problem, a field study was conducted to estimate the aquifer zone. Aquifers are a source of springs located in cavities brought under the surface of the ground which reminisce or flow. Aquifers themselves can be predicted without existence of drilling or excavation. Detection of aquifers can be done using geoelectric methods with different configurations. Our field study this time uses a schlumberger configuration with a length of 120 meters with an approximate depth of 60 meters below ground level.

Abstract

Drought usually occurs, especially during the dry season in Bontoramba, Jeneponto Regency, South Sulawesi. Therefore, it is necessary to study the potential of groundwater to meet the water needs of the Bontoramba community during the dry season. A way to identify groundwater is by using the resistivity method. This method is applied with Schlumberger configuration that gives good results vertically. The purpose of this study was to identify the potential for groundwater both in position and depth based on the results of the interpretation of measurements using the resistivity method of the Schlumberger configuration. This research is experimental research with a descriptive method. Data were processed, analyzed, and interpreted using Res2dinv. Through the results of this interpretation, modeling of the distribution of the aquifer layer in the soil is then carried out which is projected as groundwater. The results showed that the groundwater layer in path 1 and path 2 were on average at a depth of 10-30 m, path 3 and path 4 at a depth more than 30 m from the ground surface.

Abstract

XRF method to determine elemental content and FTIR test to determine the nature of chemical compounds (functional groups) of Litosol soil at the slope (elevation angle) and the distance of the research trajectory lines. The identified elemental levels are Fe, Si, Ti, K, Mn and Ca. Fe represents the highest elemental content value for each research path. Fe for paths (1-2) are 23.82 % and 37.69%, tracks (5-6) are 23.11% and 37.47%, and paths (9-10) are 40.44% and 33.99% at different elevation angles. The lowest element level is Ca. The value of Ca for each track is 0.24% and 0.66% (1-2), 0.28% and 0.30% (5-6) and 0.27% and 0.62% (9-10) for each different elevation angle. The FTIR method to determine functional groups (chemical compounds) uses the same parameters as the XRF method. The O-H functional groups were detected at wave numbers 3698.31 cm-1 and 3620.34 cm-1 with the theoretical accuracy ranges of 3700-3000 cm-1 and 3590-3650 cm-1. The C=C which is a double bond functional group was detected at wave number 1640.8 cm-1 in the theoretical range of 1610-1680 cm-1. The C-H functional group on each track was detected in three different types of wave numbers with values of 908.99 cm-1, 786.86 cm-1 and 746 cm-1, respectively. The range of wave number accuracy for C-H is 690-900 cm-1.

Abstract

A study has been conducted to determine the distribution of groundwater potential below the surface using the Schlumberger configuration resistivity geoelectrical method in Buntu Sarong Village, Masalle District, Enrekang Regency. The way the Schlumberger configuration works is to adjust the distance between the electrodes, where the distance between the constant voltage electrodes and the distance between the current electrodes change sequentially. This study was carried out in stages at three points. At sounding point 1, the groundwater potential is in the third layer with a resistivity value of 11.2 Ωm. This layer indicates the possibility of clay that has the potential to act as a water retainer or has a good water storage capacity. Meanwhile, at sounding point 2, the groundwater potential is in the third layer (14.4 Ωm) which indicates the presence of clay or fresh groundwater and at sounding point 3, there is a possibility of water potential in the second layer (2.28 Ωm) which indicates the presence of clay or fine sediment that is very saturated with water.

The location of the activity is at the foot of Mount Latimojong, Enrekang Regency with a total of 3 Schlumberger configurations. Data collection involves the government and local residents. There are 2 data needed for this activity, namely geological data and geophysical data.  Geological data was obtained from observations of rock structures above the surface and data on the depth of residents' wells around the activity location. Meanwhile, geophysical data was obtained using a resistivity meter. Data analysis was carried out using Microsoft Excel, Notepad, QGis, and IPI2WIN software to obtain a subsurface model. This model is interpreted using rock resistivity tables to map groundwater at the foot of Mount Latimojong, Enrekang Regency. After the interpretation is carried out, the groundwater drilling point is determined. The groundwater layer was found at 2 measurement points in a thin condition. This is because the rock formations at the foot of Mount Latimojong are dominated by igneous rocks originating from the Latimojong formation. The groundwater drilling point at the foot of Mount Latimojong is located at coordinates 03°25’00.00” S and 119°59’24.53” E at an altitude of 1479 mdpl and at 03°25’09.94” S and 119°59’18.74” E at an altitude of 1463 mdpl Keywords: Groundwater, Geoelectrical Method, Foot of Latimojong Mount

Abstract

ABSTRACT Observation of the crescent moon is a crucial method in determining the beginning of the Hijri month. Along with the development of technology, the use of modern optical aids such as ioptron telescopes and CCD cameras has become a promising alternative to improve observation accuracy. The main problem in this study is how effective the use of ioptron telescopes and CCD cameras is in rukyatul hilal. The main problem is then formulated into several sub-problems or research questions, namely: what are the results of using ioptron telescopes with CCD cameras in rukyatul hilal, and what is the success rate of using ioptron telescopes and CCD cameras in rukyatul hilal. This study aims to examine and analyze the effectiveness of using modern technology in rukyatul hilal. This type of research is a type of field research while the nature of the data collected is quantitative descriptive with the research approaches used are: theological normative sharia, and astronomy. The data sources in this study are based on the results of observations and documentation analysis supported by document studies. Data processing and analysis techniques are carried out through three stages, namely: data collection, data processing, and data presentation. The results of the study show that first, the results of observations using a telescope combined with a CCD camera are able to record crescent images quite well in favorable weather conditions. Second, the use of telescopes and CCD cameras in rukyatul hilal quantitatively is relatively low, namely 21.4% of 28 observations that meet the criteria with a total of 41 observations from 2021 to 2024. The implications of this study are: 1) It is necessary to develop a more comprehensive crescent observation methodology. 2) An evaluation of the effectiveness of optical instruments in rukyatul hilal is needed.

Abstract

This The main research problem of this study is how the brightness of the night sky affects the visibility of stars in Makassar City, and what solutions can be applied to overcome the limitations caused by light pollution. This problem is formulated into two sub-problems: (1) How does night sky brightness impact stellar observation in Makassar? and (2) What strategies can be used to address the challenges of observing under urban sky conditions? This study employs a descriptive mixed-method approach with a falak-astronomical perspective. Quantitative data were obtained from secondary measurements of night sky brightness using Light Pollution Map values expressed in mag/arcsec² and classified through the Bortle Scale. Qualitative analysis was conducted by interpreting the observational implications of skyglow on falak practices and stellar visibility. Data were collected from four observation locations: Pantai Losari, Pantai Tanjung Layar Putih, UIN Samata, and Malino.The results show significant variation in sky brightness across the locations. Pantai Losari recorded the lowest darkness level (18.85 mag/arcsec²), categorized as urban sky, where only bright stars can be observed. Meanwhile, Malino showed the darkest condition (21.01 mag/arcsec²), classified as rural sky, allowing clearer visibility of faint stars. These findings confirm that increasing urban light pollution reduces the limiting magnitude and restricts astronomical observation in falak studies. The implications of this research are: (1) night sky brightness is a crucial factor in supporting observational astronomy; (2) the study highlights the need for darker observation zones around Makassar; and (3) it strengthens the relevance of integrating falak tradition with modern sky-quality analysis to preserve accurate celestial observation.

Abstract

Abstract This study discusses the determination of the direction of the Qibla using the azimuth of the cumulonimbus cloud as an alternative to determining the direction of the Qibla in the perspective of the integration of astronomy and meteorology. This research is motivated by the importance of the direction of the qibla in prayer and the need for alternative methods of determining the direction of the qibla when modern tools or astronomical observations cannot be used optimally. Therefore, this study aims to find out: 1) how to determine the direction of the qibla using the azimuth of the cumulonimbus cloud; 2) How is the accuracy of the azimuth of the cumulonimbus cloud in determining the direction of the Qibla. Cumulonimbus clouds are chosen because they have the characteristics of vertical growth and a specific direction of movement that can be visually observed in the atmosphere. This study uses the library research method with a normative sharia and descriptive approach. Data were obtained through literature reviews in the form of books, journals, scientific articles, and relevant sources that discuss the direction of the qibla, astronomy, meteorology, azimuth, and characteristics of cumulonimbus clouds. The analysis was carried out by examining the relevance between the concept of azimuth in astronomy and the movement pattern of cumulonimbus clouds in meteorology. The results of the study show that the azimuth of cumulonimbus clouds can theoretically be used as an alternative indicator in determining the direction of the qibla, especially when the position of the sun and other celestial bodies cannot be observed directly. However, the accuracy level of this method is influenced by atmospheric conditions, wind direction, cloud stability, and the geographical position of the observer. Therefore, this method cannot replace the main astronomical method, but it can be used as an alternative approach based on natural phenomena. This study shows the relevance between astronomy and meteorology in the development of adaptive and contextual Qibla direction determination methods. The implications in this study need to be positioned as a supporting alternative in the analysis of the falak, while the astronomical method that has a better level of precision, stability, and validity of measurements remains the main foundation in determining the direction of the qibla.
