Abstract

Kualitas air sungai memainkan peran yang penting dalam mendukung berbagai ekosistem air dan aktivitas manusia. Namun, Sungai Gentung saat ini mengalami perubahan kondisi yang dapat dilihat secara fisik. Hal ini kemungkinan dipengaruhi oleh semakin meningkatnya jumlah penduduk dan aktivitas ekonomi yang intensif di sepanjang bantaran sungai yang dapat meningkatkan risiko pencemaran air. Penelitian ini bertujuan untuk mengetahui indeks pencemaran dan prediksi distribusi kualitas air sungai Gentung, Kabupaten Pangkep. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif deskriptif dengan menggunakan parameter fisik seperti suhu, Total Suspended Solids (TSS), dan Total Dissolved Solids (TDS) serta parameter kimia yaitu pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), dan Chemical Oxygen Demand (COD). Selain itu, Analisis Spatial Inverse Distance Weighted juga dilakukan untuk menggambarkan profil distribusi kualitas air sehingga diperoleh data sebaran kualitas air sungai pada empat titik pengambilan sampel yang dipilih secara purposive sampling. Hasil penelitian menunjukkan bahwa kondisi kualitas air Sungai Gentung, Kabupaten Pangkep dalam keadaan tercemar ringan hingga sedang. Indeks pencemaran titik satu yaitu 5,66 (cemar sedang), titik kedua 5,78 (cemar sedang), titik ketiga 6,04 (cemar sedang), dan titik keempat 2,39 (cemar ringan). Selain itu, hasil Analisis Spatial Inverse Distance Weighted dengan merujuk dari hasil pengujian laboratorium dan perbandingan syarat baku mutu menunjukkan distribusi kualitas air sungai pada tujuh parameter pengujian yang terindikasi tidak memenuhi syarat baku mutu adalah Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), dan Chemical Oxygen Demand (COD). Penelitian ini dapat menjadi bahan rujukan dan rekomendasi bagi pihak pemangku kepentingan untuk mengambil langkah penanganan permasalahan lingkungan yaitu kualitas air Sungai Gentung, Kabupaten Pangkep.

Abstract

One source of raw water that is often used by humans is groundwater, namely water that occupies cavities in the layers of rock beneath the earth's surface. Groundwater is often used as a source of raw water or a source of clean water by the community apart from river and lake water. Each region has its own level of groundwater potential that can be utilized. The purpose of the analysis carried out is to determine the distribution of potential groundwater in each sub-district area in Gowa Regency through the use of a Geographic Information System (GIS), by applying the overlay method to a number of variables which are factors that influence the presence of groundwater, such as slope, use land, soil type, geology, and rainfall. The results of the analysis that has been carried out show that Gowa Regency has groundwater potential that is spread over each of its sub-districts, where it is divided into a number of potential levels of groundwater availability starting from very low, low, medium, high, and very high.

Abstract

This study aims to develop a valid, practical, and effective digital interactive Islamic education coursebook at Universitas Khairun using the ADDIE development model. The research process began with a needs analysis which indicated that students required a coursebook with simplified content divided into seven main topics. The design phase involved determining the topics, collecting references, creating a matrix, and organizing learning objectives. The developed coursebook underwent two validation steps: expert evaluation and product testing. Expert validation results showed an average score of 3.37, while product testing revealed an increase in pre-test scores from 70.00 to 81.04, a difference of 16.23%. Practicality assessment of the coursebook revealed that 95.07% of respondents rated it as “practical”. Additionally, the effectiveness of the coursebook was demonstrated by a 16.44% increase in the average pre-test and post-test scores of students. These findings indicate that the developed digital Islamic education coursebook meets the criteria for validity, practicality, and effectiveness, making it an effective learning resource at Khairun University

Abstract

This research aims to develop Quizizz-based learning media and determine its feasibility and effectiveness in improving student learning outcomes in Social Sciences (IPS) subjects at SMP Negeri 2 Ternate City. The background of this research is based on the low learning outcomes of students caused by the use of learning media that is less varied and not optimal in utilizing digital technology. The research method used is research and development with stages including needs analysis, media design, product development, trial, and evaluation. The subject of the study is a student of the State Junior High School 2 Ternate City. Data collection techniques are carried out through observation, questionnaires, and learning outcome tests. The results of the study show that the Quizizz learning media is declared feasible to use based on the results of expert validation and positive student responses. In addition, the use of Quizizz media has been shown to be effective in improving student learning outcomes, which is shown by the increase in average scores and the percentage of learning completeness after the application of the media. Thus, Quizizz learning media can be used as an alternative to innovative and effective social studies learning media at SMP Negeri 2 Ternate City.
