Abstract

Sungai Bone mengalami pendangkalan di bagian muaranya. Tingginya angkutan sedimen melayang pada Sungai Bone terlihat dari kondisi fisik air yang keruh di sepanjang tahun baik musim kemarau maupun penghujan yang disebabkan oleh banyak faktor diantaranya erosi. Penelitian ini bertujuan untuk mengevaluasi besar laju angkutan sedimen melayang pada daerah hulu, tengah, dan hilir Sungai Bone. Metode penelitian yang dilakukan yaitu dengan membandingkan pengukuran sesaat dan tiga Metode Empiris berupa Metode Lane and Kalinske, Metode Einstein dan Metode Chang Simon and Richardson. Pengambilan sampel yang dilakukan di lapangan berupa sampel sedimen melayang, sampel sedimen dasar dan pengukuran hidrometri pada sungai. Sampel diuji di Laboratorium untuk mendapatkan parameter yang diperlukan pada formulasi yang dipilih. Hasil perhitungan laju angkutan menggunakan Metode Sesaat berkisar antara 925,40-1.179,81 ton/tahun, menggunakan metode Lane and Kalinske berkisar antara 2.180,51- 3.492,05 ton/tahun, menggunakan Metode Einstein berkisar antara 22,23-33,32 ton/tahun, dan menggunakan Metode Chang Simon and Richardson berkisar antara 45,12-68,35 ton/tahun. Persentase beda perbandingan hasil perhitungan antara Metode Sesaat terhadap Metode Empiris sebesar 152,55% lebih besar untuk Sesaat-Lane and Kalinske, 97,52% lebih kecil untuk Sesaat-Einstein dan 94,99% lebih kecil untuk Sesaat-Chang Simon and Richardson.

Abstract

Bolango River is a river that has potential as a source of raw water and irrigation for communities in Gorontalo Province. Sedimentation in the upstream and downstream of the river causes a decrease in river function. This research aims to predict the amount of suspended sediment transport discharge in Bolango River which is compared with the results of calculations using empirical methods. The calculation method used is the calculation of the instantaneous method (USBR) which is compared with three empirical methods namely Einstein, Lane and Kalinske, and Chang, Simon and Richardson by taking sediment samples and measuring river hydrometry. Based on the results of the calculation of the amount of drift sediment transport in Bolango River with the instantaneous method (USBR) ranged from 13,039-158,028 tonnes/year, Lane and Kalinske approach 26,013-253,138 tonnes/year, Einstein approach ranged from 12,458-50,350 tonnes/year and Chang, Simons & Richardson approach ranged from 1,598-19,257 tonnes/year. The closest comparison result to the instantaneous method (USBR) is the Lane and Kalinske approach with a percentage of 99.6% in the upper reaches of the river, 105.33% in the middle reaches, and 60.18% in the lower reaches.

Abstract

Learning interest is one of the internal factors that determines students’ academic success. In the context of Hydrologic Engineering courses, which require analytical understanding, strong learning motivation is needed to participate in learning optimally. This research was conducted due to students' low learning outcomes, even though they regularly attended lectures. Therefore, this study aimed to evaluate the influence of learning interest on student learning outcomes in the hydrologic engineering course in the Civil Engineering Study Program, Universitas Negeri Gorontalo. This quantitative research, with an ex post facto approach, used all students (84 people) who had taken the hydrologic engineering course as a population and a sample (total sampling technique). Data were collected through learning interest questionnaires and academic score documentation, then analyzed using the Wilcoxon Signed Ranks Test. Based on the analysis, there was a significant relationship between learning interest and student learning outcomes. Students with a high interest in learning tend to get better academic grades. Aspects of interest, attention, and active involvement in learning have been shown to play an essential role in academic achievement. Thus, it is recommended to implement interactive and contextual learning methods and utilize supporting facilities, such as simulation software and real-life case studies, to improve student motivation and learning outcomes.

Abstract

The agricultural sector plays a crucial role in realizing Asta Cita's vision of food security, one of which is through the optimization of the Toraut Dam in Toraut Utara Village. However, increasing water demand for rice field intensification and expansion, alongside limited irrigation water supply, necessitates efficient irrigation system management. This research aims to analyze water loss in the distribution of irrigation networks in the Toraut Irrigation Area. The study used primary data (cross-sectional geometry and canal flow velocity measured using the surface buoy method) and secondary data (climatological records, irrigation network maps, and supporting documents). The analysis included calculating flow discharge, water loss due to evaporation using the Penman method, seepage, irrigation efficiency, and water loss in each channel segment. Results showed the highest discharge in the primary channel was at SPKr I upstream (5.586 m³/s), and the lowest was at SPKr 7 downstream (0.136 m³/s). In the secondary channel, the highest discharge was found at Secondary Tumpah upstream (0.895 m³/s), while the lowest was at Secondary Dumara downstream (0.043 m³/s). The highest efficiency in the primary channel was at SPKn (98.55%), while the lowest was at SPKr 6 (70.15%). In the secondary channels, the highest efficiency was at Secondary Tongot 2 (97.76%), and the lowest at Secondary Dumara (35.87%). The greatest water loss in the primary channel occurred at SPKr 6 (29.85%), and the least at SPKn (1.45%). For secondary channels, the greatest water loss occurred in Secondary Dumara (64.13%) and the least in Secondary Tondait (0.75%).

Abstract

The Alo Watershed (DAS Alo) is a-subwatershed of the Limboto Watershed loacted in Gorontalo Regency, covering an area of 210,495 km2. Frequent flooding in the Alo Watershed has caused significant damage, with various contributing factors including high rainfall, low public awareness of environmental issues, and sparse vegetation cover. To assess the impact of land condition changes on river discharge in the Alo Watershed, the Hydrologic Engineering Centre - Hydrologic Modelling System (HEC – HMS) program was employed, utilizing the Soil Conservation. The analysis using HEC-HMS program revealed that the discharge under 2019 land use conditions was higher than that projected in the 2032 Regional Spatial Plan (RTRW). To reduce future discharge, land use management was simulated by decreasing certain land uses, which were reallocated to other types of use, while adhering to the 2032 RTRW guidelines. The simulation of land use management under Scenario 1, with a return period of T years, succeeded in reducing flood discharge by 8,65%-14,67% compared to the 2019 conditions. Scenario 2 achieved a reduction of 8,43%-14,70%. Both scenario effectively reduced flood discharge beyond the 2019 conditions, indicating the potential of these strategies to mitigate future flood risks.
