Abstract

ABSTRAK: Penelitian ini bertujuan untuk menganalisis kondisi sosial dan ekonomi masyarakat di sekitar Tempat Pembuangan Akhir (TPA) Antang serta mengidentifikasi dampak keberadaan TPA terhadap kehidupan sosial ekonomi warga Kelurahan Tamangapa, Kecamatan Manggala, Kota Makassar. Penelitian menggunakan pendekatan kuantitatif dengan metode survei melalui penyebaran kuesioner kepada 391 responden yang ditentukan menggunakan rumus Slovin. Analisis data dilakukan dengan Analisis Deskriptif untuk menggambarkan karakteristik dan kondisi sosial ekonomi masyarakat, serta uji Chi-Square untuk mengetahui hubungan antara variabel sosial dan ekonomi dengan keberadaan TPA. Hasil penelitian menunjukkan bahwa kondisi sosial masyarakat dipengaruhi oleh faktor kesehatan, kenyamanan lingkungan, dan interaksi sosial, sementara kondisi ekonomi didominasi oleh pekerjaan sektor informal yang berkaitan dengan aktivitas TPA. Uji Chi-Square mengonfirmasi bahwa beberapa variabel sosial dan ekonomi memiliki hubungan signifikan dengan keberadaan TPA Antang. Secara keseluruhan, TPA memberikan dampak ganda: menimbulkan gangguan lingkungan namun juga membuka peluang ekonomi bagi masyarakat sekitar. KATA KUNCITPA Antang, Kondisi Sosial Ekonomi, Masyarakat, Sampah, Chi-Square. ABSTRACT: This study aims to analyze the social and economic conditions of communities living around the Antang Final Disposal Site (TPA Antang) and to identify the impacts of the facility on the social and economic aspects of residents in Tamangapa Urban Village, Manggala District, Makassar City. A quantitative research approach was employed using a survey questionnaire distributed to 391 respondents determined through the Slovin formula. Data were analyzed using descriptive statistics to describe the demographic profile and socio-economic conditions, as well as the Chi-Square test to examine the relationship between social and economic variables and the existence of the TPA. The results indicate that social conditions are influenced by health factors, environmental comfort, and social interactions, while economic conditions are dominated by informal sector jobs related to TPA activities. The Chi-Square test confirmed that several social and economic variables have a significant relationship with the presence of TPA Antang. Overall, the TPA generates dual impacts: environmental disturbances and socio-economic opportunities for surrounding communities.Keywords:Antang landfill, socio-economic conditions, community, waste management, Chi-Square.

Abstract

ABSTRAK: Penstock merupakan komponen vital dalam sistem pembangkitan listrik tenaga air karena berfungsi menyalurkan aliran air bertekanan dari bendungan menuju turbin. Kinerja penstock sangat dipengaruhi oleh kondisi hidraulik di dalamnya, khususnya fluktuasi debit yang dapat menimbulkan perubahan tekanan, kehilangan energi, dan potensi terjadinya water hammer. Penelitian ini bertujuan untuk mengkaji kinerja penstock pada PLTA Bili Bili di bawah kondisi variasi debit operasi, serta menganalisis pengaruh fluktuasi debit terhadap parameter-parameter hidraulik utama seperti tekanan, kecepatan aliran, dan efisiensi penyaluran energi. Data yang dikaji meliputi karakteristik penstock, variasi debit harian, tekanan operasi, serta data kinerja turbin. Analisis dilakukan untuk mengetahui hubungan antara perubahan debit dengan perubahan tekanan internal, head loss, dan respons sistem terhadap potensi transien aliran. Hasil penelitian menunjukkan bahwa fluktuasi debit memiliki pengaruh signifikan terhadap karakteristik hidraulik penstock. Pada debit tinggi terjadi peningkatan tekanan statis dan kehilangan energi yang lebih besar, sedangkan pada debit rendah penurunan tekanan menyebabkan efisiensi penyaluran energi menurun. Studi ini diharapkan dapat memberikan kontribusi dalam optimasi operasi penstock dan peningkatan keandalan sistem pembangkitan pada PLTA Bili Bili.KATA KUNCIPenstock, Fluktuasi Debit, Hidraulika Penstock, PLTA Bili Bili, Water hammer, Head loss. ABSTRACT: Penstock is a vital component in a hydropower generation system because it functions to channel the flow of pressurized water from the dam to the turbine. The performance of the penstock is greatly influenced by the hydraulic conditions in it, especially discharge fluctuations that can cause pressure changes, energy loss, and the potential for water hammering. This study aims to examine the performance of the penstock in the Bili Bili hydropower plant under conditions of operating discharge variations, as well as analyze the effect of discharge fluctuations on key hydraulic parameters such as pressure, flow speed, and energy distribution efficiency. The data studied included penstock characteristics, daily discharge variations, operating pressure, and turbine performance data. The results of the study show that the discharge fluctuations have a significant influence on the hydraulic characteristics of the penstock. At high discharge there is an increase in static pressure and greater energy loss, while at low discharge there is a decrease in pressure causing the efficiency of energy distribution to decrease. This study is expected to contribute to the optimization of penstock operations and improve the reliability of the generation system at the Bili Bili hydropower plant.Keywords:Penstock, Discharge Fluctuation, Penstock Hydraulics, Bil Hydropower, Water hammer, Head loss
