Abstract

Tujuan penelitian ini adalah untuk mengetahui kecepatan aliran disekitar pier jembatan Ruas Noling-Padang Tujuh Kecamatan Bua Ponrang Kabupaten Luwu. Dari hasil penelitian menunjukkan adanya ketidakstabilan aliran. Hal ini ditandai dengan perubahan kecepatan aliran yang naik dan turun secara tidak teratur dalam waktu pengamatan yang singkat. Hasil menunjukkan bahwa kecepatan aliran maksimum di bagian hulu sungai sebesar 1,7 m/s, kecepatan aliran maksimum di sekitar pier jembatan sebesar 2,3 m/s dan kecepatan aliran maksimum di bagian hilir sungai sebesar 1,6 m/s. Pola ini menunjukkan bahwa kondisi aliran tidak mencapai kestabilan hidraulik, sehingga kemungkinan besar terjadi transisi antara aliran laminar dan turbulen. The purpose of this study was to determine the flow velocity around the pier of the Noling-Padang Tujuh Bridge in Bua Ponrang District, Luwu Regency. The results showed flow instability. This was characterized by irregular changes in flow velocity that rose and fell within a short observation period. The results showed that the maximum flow velocity in the upstream part of the river was 1.7 m/s, the maximum flow velocity around the bridge pier was 2.3 m/s, and the maximum flow velocity in the downstream part of the river was 1.6 m/s. This pattern indicates that the flow conditions did not reach hydraulic stability, so that a transition between laminar and turbulent flow was likely to occur.

Persepsi masyarakat terkait tingkat ketersediaan prrasarana dasar di kawasan permukiman perkotaan Kelurahan Tangkoli kurang memadai sebagai kawasan permukiman perkotaan. Hal ini disebabkan oleh karena beberapa prasarana dasar yang kurang memadai seperti prasarana jalan dan prasarana sanitasi. Meskipun begitu terdapat prasarana yang sudah dikatakan baik seperti prasarana drainase dengan persentase 53,1%. Prasarana persampahan dengan persentase 57,9% dan prasarana air bersih dengan persentase 63,2%. The purpose of this study is to determine public perceptions regarding the availability of basic infrastructure in the urban residential area of Tangkoli Village, Maniangpajo District, Wajo Regency. The type of research is descriptive quantitative, while the research methods used include field surveys, interviews, and documentation. Public perceptions regarding the level of availability of basic infrastructure in the urban residential area of Tangkoli Village are inadequate as an urban residential area. This is due to the inadequate availability of several basic infrastructures such as road infrastructure and sanitation infrastructure. However, there are infrastructures that are considered good, such as drainage infrastructure with a percentage of 53.1%. Waste infrastructure with a percentage of 57.9% and clean water infrastructure with a percentage of 63.2%.
