Abstract

Kondisi infrastruktur di Kabupaten Jeneponto dinilai belum optimal untuk memberikan nilai tambah terhadap PDRB di Kabupaten Jeneponto. Penelitian ini bertujuan untuk mengetahui pengaruh jalan terhadap pertumbuhan ekonomi di Kebupaten Jeneponto dan mengetahui pengaruh listrik terhadap pertumbuhan ekonomi di Kebupaten Jeneponto. Penelitian ini bersifat deskriptif kuantitatif dengan menggunakan analisis regresi data panel dalam kurun waktu 2021 hingga 2025 di kabupaten Jeneponto. Objek yg diteliti meliputi (1) PDRB (pertumbuhan ekonomi) (2) Infrastruktur yang terdiri dari: Infrastruktur jalan dan Infrastruktur listrik. Hasil penelitian menunjukkan bahwa variable jalan dan listrik memiliki pengaruh yang signifikan terhadap pertumbuhan ekonomi di Kabupaten Jeneponto dengan tingkat keyakinan sebesar 95 persen. Hal ini dapat dilihat apabila panjang jalan dan Konsumsi listrik naik sebesar 1 persen, maka pertumbuhan ekonomi akan naik sebesar 61.48186 (jalan) persen dan 44.86282 (listrik) persen.

Abstract

Clay soils often exhibit problematic characteristics. Expansive clay, which has swelling and shrinkage properties that are influenced by its moisture content. The study analyze the effect of lime mixing on the swelling and shrinkage behavior of soil. The method used involves mixing Fakfak clay with lime in proportions of 0%, 2%, 4%, 6%, and 8%, with a curing period of 3 days. The original soil used is classified as OH or A-7-5, with an average moisture content of 50.51%, a bulk density of 0.612 g/cm³, a specific gravity of 2.3, a liquid limit of 61.59%, a plastic limit of 48.86%, and a shrinkage limit of 32.94%, with a plasticity index of 12.73%, classified as medium plasticity and cohesive. The results showed that soil plasticity decreased with increasing lime content, with the lowest value found at 8% lime (1.04%). The largest shrinkage limit was found in the 2% lime mixture (33.27%), while the smallest was in the 8% lime mixture (28.77%). The conclusion lime mixing is effective in improving the soil's condition, with the 8% lime mixture demonstrating a stable composition with respect to the swelling behavior, compared to both the original soil and other lime mixtures.
