ABSTRAKSungai adalah tempat atau wadah serta jaringan pengaliran air mulai dari mata air sampai muara dengan dibatasi kanan dan kirinya serta sepanjang pengalirannya oleh garis sempadan, ada dua fungsi utama sungai secara alami yaitu mengalirkan air dan mengangkut sedimen hasil erosi pada Daerah Aliran Sungai dan alurnya, kedua fungsi ini terjadi bersamaan dan saling mempengaruhi. Peristiwa sedimentasi umumnya terjadi pada hilir sungai, karena pada bagian hilirlah aliran sungai akan melambat atau terhenti, peristiwa sedimentasi dapat merubah elevasi dasar sungai sehingga akan mempengaruhi kondisi morfologi sungai, perubahan morfologi sungai tersebut sedikit banyak akan mempengaruhi ketersediaan air di lingkungan sekitar, pada musim kemarau akan berdampak kekurangan air dan pada musim hujan akan mengalami kebanjiran. Salah satu peristiwa sedimentasi dapat kita jumpai pada hilir sungai Kambu.Penelitian ini bertujuan untuk mengetahui besarnya debit aliran dan besarnya sedimen dasar yang terjadi pada tiga titik di hilir sungai kambu. Pada penelitian ini dilakukan pengukuran langsung pada tiga titik di hilir sungai Kambu untuk mendapatkan data morfologi sungai dan sampel sedimen dasar. Sampel sedimen kemudian diperiksa di laboratorium untuk mendapatkan ukuran diameter butiran dengan persentase lolos 35% dan 50% (D35, D50). Data-data yang telah diperoleh selanjutnya dianalisis menggunakan rumus empiris yaitu metode Schoklitsch dan metode Haywood.Hasil analisis menunjukkan besarnya debit aliran pada tiga titik di hilir sungai Kambu pada lokasi 1 sebesar 1,965 m3/s, pada lokasi 2 sebesar 3,129 m3/s, dan pada lokasi 3 sebesar 6,262 m3/s. Sedimen bed load yang terjadi pada tiga titik di hilir sungai Kambu dengan menggunakan metode Schoklitsch pada lokasi 1 sebesar 355,9763 m3/hari, pada lokasi 2 sebesar 527,7918 m3/hari, dan pada lokasi 3 sebesar 2117,924 m3/hari, sedangkan dengan metode Haywood diperoleh besaran sedimentasi pada lokasi 1 sebesar 446.395 m3/hari, pada lokasi 2 sebesar 1.149.291 m3/hari, dan pada lokasi 3 sebesar 12.169.865 m3/hari. Kata Kunci : Hilir sungai, Sedimentasi, Sedimen dasarABSTRACTThe river is a place or container and network of water flowing from the spring to the estuary which is restricted to the right and left and along the flow by the demarcation line, there are two main functions of the river naturally, namely flowing water and transporting sediment from erosion in the watershed and its flow, second this function occurs simultaneously and affects each other. Sedimentation events generally occur at the downstream of the river, because in the downstream part of the river flow will slow down or stop, sedimentation events can change the elevation of the river bed so that it will affect the condition of river morphology, changes in the morphology of the river will more or less affect the availability of water in the surrounding environment, during the dry season will impact water deficit and in the rainy season will be flooded. One of the sedimentation events can be found on the downstream of the Kambu River.This study aims to determine the magnitude of the flow rate and the amount of bed load sediment that occurs at three points downstream of the river Kambu. In this study, direct measurements were taken at three points downstream of the Kambu River to obtain river morphology data and bed load sediment samples. Sediment samples are then examined in the laboratory to obtain a diameter size of granules with percentages of 35% and 50% (D35, D50). The data that has been obtained are then analyzed using an empirical formula, Schoklitsch method and Haywood method.The results of the analysis show the magnitude of the flow discharge at three points in the downstream of the Kambu river at location 1 was 1.965 m3/s, at location 2 was 3.129 m3/s, and at location 3 was 6.262 m3/s. bed load sediment that occurs at three points downstream of the river Kambu using the Schoklitsch method at location 1 is 355,9763 m3/day, at location 2 is 527,7918 m3/day, and at location 3 is 2117,924 m3/day, while with Haywood method the amount of sedimentation at location 1 is 446395 m3/day, at location 2 is 1.149.291 m3/day, and at location 3 is 12.169.865 m3/day.

The Lupia Village irrigation network was formed in 1981 through farmer groups from the results of non-governmental organizations. Currently the government has given attention and assistance both through the village fund budget and central government funding assistance, however, there is still a need for program sustainability from related parties. The results of the identification were carried out, namely that there were still few people who did not understand about the more effective use of irrigation water, so that there was always a crop failure where other plots of rice fields had excess water while the farthest plots did not get water. The area of land used by the community is currently around + 35 hectares, but the available land and the potential to be used as rice fields are around + 90 hectares, so that what has not been functioned as rice fields is about + 55 hectares. Seeing this condition, it is very potential to be developed to be able to increase the production of rice fields in Lupia Village, from this potential, the Lecturer of the Faculty of Engineering, Halu Oleo University as part of the Tridarma of Higher Education, carries out community service activities through the transfer of knowledge so that the community can develop, increase production, and improve community welfare, especially the residents of Lupia Village, Kabangka District, Muna Regency. The methods used are socialization, technical guidance, training on procedures for implementing technical irrigation canal development so that water is not wasted and can be fully utilized by farming communities. The expected result is that the community can increase the yield of lowland rice production. Seeing the potential of Lupia Village in Kabangka District, it is hoped that the program can be carried out continuously so that it can increase income and a better standard of living for its people.

Perubahan fungsi lahan mengakibatkan kondisi DAS secara fisik dan lingkungan semakin menurun. Hal ini akan berhubungan dengan peningkatan debit banjir dalam DAS tersebut. Demikian juga pada DAS Karalloe, yang mengalami perisitiwa banjir pada tahun 2018 yang lalu. Penelitian ini dilakukan untuk menganalisis perubahan koefisien aliran yang terjadi di dalam DAS Karalloe. Data yang digunakan dalam penelitian ini adalah data curah hujan, luas DAS, panjang sungai dan perubahan penggunaan lahan di dalam DAS Karalloe. Metode rasional digunakan untuk menganalisis peningkatan koefisien aliran permukaan (run off) akibat perubahan fungsi lahan yang terjadi. Hasil penelitian menunjukkan bahwa pada DAS Karalloe, telah terjadi perubahan fungsi lahan dari tahun 2009 sampai 2018, hal ini menunjukaan peningkatan koefisien run off 0,166 menjadi 0,173 pada tahun 2018. Peningkatan debit banjir menunjukkan pada tahun 2009 sebesar 363.394 m3/detik dan untuk tahun 2018 sebesar 392.283 m3/detik pada kala ulang 20 tahun.Kata kunci; Koefisien Run Off, Banjir, DAS

Surf zone is the most important area in the analysis of the coastal process because in that area three waves are no longer stable due to the energy lost after the wave breaks so that high turbulence occurs which causes the sediment transport process. The purpose of this research was to determine the width of the surf zone during high tide and low tide on the coast of Makassar City starting from the estuary of the Jeneberang River to the estuary of the Tallo River. Data analysis technique used in the form of wind direction and velocity analysis use the application surfer, fortranC++and GIS, effective fetch analysis, wave forecasting, and breaking wave analysis then measured the width of the surf zone using the bathymetry map of the research site. The results of this research are the average width of the surf zone in the research site affected by the tides where the widest average surf zone width occurs at low tide with a width of 618 meters and the narrowest average width of the surf zone occurs when the tide is 35 meters wide.Keywords—Coastal Area, Tides, Wide Surf ZoneDOI : 10.5281/zenodo.1911853
