Abstract

Introduction: Eye disease, especially in adolescents, has various symptoms. Currently, most adolescents pay little attention to the condition of the eyes. The assumption circulating in society is that the disease will heal on its own without the need for medical treatment. As a result, many adolescents experience delays in treatment. Method: This method is used because forward chaining uses a search value or reasoning that starts from facts to get conclusions from these facts to assume the degree of confidence of an expert. The data in this study are data on symptoms and eye types in adolescents aged 12-15 years obtained through interviews with experts at the Smec Palu eye clinic. This study uses 3 tests namely Alpha testing, beta testing, and accuracy testing. Results and Discussion: System testing is done through alpha testing, beta testing, and accuracy testing. Alpha testing shows that the system components function as expected. Beta testing uses a questionnaire that produces a percentage of 86% for System Quality, 86% for Information Quality, and 88% for User Satisfaction. Accuracy testing shows that the system has 100% accuracy because all test data matches the results of expert analysis. This shows that the system has very good accuracy. Conclusion: Expert system testing to diagnose eye diseases in adolescents aged 12-15 years with the forward chaining method shows positive results. Alpha testing ensures that all features function properly, while beta testing gives a score of 86% for System and Information Quality, and 88% for User Satisfaction. Accuracy testing showed 100% results. This system is effective for diagnosing eye diseases based on symptoms.

Abstract

Introduction: This research discusses the availability of groundwater in the Ngatabaru Village area. The use of groundwater, which tends to be more intensive and is not in accordance with its availability and utilization zone, ultimately has an impact on the local environment. Method: This study used the overlay method to determine the groundwater conditions in the study area. This method uses 7 parameters to determine the groundwater zone, namely lithology, hydrogeology, land cover, rainfall, slope, drainage density, and lineament density. Results and Discussion: This map produces 5 groundwater occurrence zones which show that 34.32% of the study site is an area with very low groundwater occurrence, then 37.19% is an area with low groundwater occurrence, 9.08% is an area with moderate groundwater occurrence, 12.91% is an area with high groundwater occurrence and 6.5% is an area with very high groundwater occurrence. Conclusion: Based on the analysis, Kelurahan Ngatabaru has low annual rainfall, ranging from 0 to 800 mm. The slope is steep in the east and slopes to the west, with forest land cover in the east and scrub and settlements in the west. Geologically, the area consists of schist, granite, and conglomerate lithologies, and has aquifers with high, low, and little productivity.

Abstract

Introduction: The Patukuki area in the Central Peling sub-district falls administratively within the geographical coordinates of 123°01'00" – 123°01'3" longitude and 01°24'00" – 01°27'00" latitude. Method: Channel Sinuosity (S) measures river influence on landscapes by comparing actual river length to valley length. Mountain-front sinuosity (Smf) evaluates mountain-front curvature using base and straight-line lengths. The Valley Floor Width to Width-to-height ratio (Vf) identifies regions of rapid uplift, with lower values indicating higher activity. The Asymmetric Factor (AF) detects tectonic tilting in drainage basins by comparing the area of the right-hand side sub-basin to the total area. Results and Discussion: Based on the analysis conducted, the findings are as follows: Channel Sinuosity analysis shows that sub-bases 1, 2, and 3 have high tectonic activity, while sub-base 5 has moderate activity, and sub-base 3 is low. Stream Morphology Frequency (Smf) analysis shows moderate tectonic activity in sub-bases 1, 3, 4, and 5, and sub-base 2 with an average Smf value of more than 1.5. Valley floor width to height ratio (Vf) shows low tectonic activity in all sub-bases. Anisotropy of Magnetic Susceptibility (AF) shows that sub-bases 1 and 5 have high tectonic activity, sub-bases 3 and 4 are moderate, and sub-base 3 is low. The IATR values of sub-bases 1, 4, and 5 are between 1.5 and less than 2, while sub-bases 2 and 3 show moderate tectonic activity with IATR values between 2 and less than 2.5.Conclusion: In summary, tectonic activity in the Patukuki watershed ranges from moderate to high based on the various analyzed indices.

Abstract

Introduction: In the marine environment there are types of Protista called foraminifera which are divided into 2 (two) which are called planktonic foraminifera and benthonic foraminifera, where planktonic foraminifera live by being anchored in mud or sediment. Method: The abundance of fossil planktonic foraminifera and benthonic foraminifera in the Ako area is very diverse, namely: 192 species of planktonic foraminifera and 381 species of benthonic foraminifera. Results and Discussion: The living environment of foraminifera in the study area is in the middle neritic zone with a depth of 30-100 m, where sunlight can still penetrate so that nutrients and oxygen for foraminifera are very sufficient. Salinity varies between 30-40% and temperature is divided into hot and warm climates. In hot climates, planktonic foraminifera such as Globorotalia Tumida and Globorotalia Menardii are found, while in warm climates Orbulina bilobata and Globorotalia Dutertrei are found. Benthonic foraminifera living at this depth include Cibicides Wuellerstorfi and Lenticulina orbicularis. Changes in the marine environment in the middle neritic zone are influenced by strong wave dynamics, as well as sea level fluctuations that cause regression and transgression, lifting sedimentary rocks to the surface. Conclusion: The foraminifera fossils in the Ako area are highly diverse, with 192 species of planktonic foraminifera and 330 species of benthonic foraminifera. The shells of foraminifera in this area are relatively large because nutrients from sunlight are abundant. Its paleoenvironment is in the middle neritic zone with a depth of 30-200 m, salinity of 3-30%, and temperature divided into hot and warm climates. Changes in the marine environment in this zone are influenced by sea level fluctuations that cause a decrease (regression) and increase (transgression) of sea level, as well as the removal of sedimentary rocks to the surface.
