Abstract

Kerusakan perkerasan jalan yang bisa di temui di jalan tersebut seperti jalan yang berlubang, bergelombang, retak, amblas, dan berbagai jenis kerusakan lainnya. Bertujuan untuk mengetahui jenis dan tingkat kerusakan jalan lera kecamatan wotu kabupaten luwu timur dengan menggunakan metode bina marga. Metode penelitian yang digunakan adalah metode kuantitatif.  Dari hasil penelitian maka dapat diketahui bahwa jenis kerusakan yang ada pada ruas jalan lera kecamatan wotu kabupaten luwu timur yaitu segmen 1 retak kulit buaya dan lubang, segmen 2 amblas, dan retak kulit buaya di segmen amblas, retak kulit buaya, dan retak memanjang, di segmen 4 amblas, dan retak memanjang di segmen 5 retak kulit buaya, dan lubang, di segmen 6 amblas, lubang, dan  retak kulit buaya di segmen 7 amblas, dan retak kulit buaya sedangkan di segmen 8 amblas, segmen 9 retak kulit buaya, amblas, dan lubang dan di segmen 10 retak kulit buaya, dan lubang dan didapatkan  rata rata nilai kondisi jalan sebesar 5,3. Pavement damage encountered on the road includes potholes, bumps, cracks, sinkholes, and various other types of damage. The aim was to determine the type and extent of damage to Lera Road, Wotu District, East Luwu Regency, using the Bina Marga method. The research method used is a quantitative method.From the results of the study, it can be seen that the types of damage on the Lera road section, Wotu subdistrict, East Luwu Regency, namely segment 1 crocodile skin cracks and holes, segment 2 collapse, and crocodile skin cracks in the segment collapse, crocodile skin cracks, and longitudinal cracks, in segment 4 collapse, and longitudinal cracks in segment 5 crocodile skin cracks, and holes, in segment 6 collapse, holes, and crocodile skin cracks in segment 7 collapse, and crocodile skin cracks while in segment 8 collapse, segment 9 crocodile skin cracks, collapse, and holes and in segment 10 crocodile skin cracks, and holes and the average road condition value is 5.3.

Abstract

Tujuan penelitian ini adalah untuk mengetahui karakteristik sedimen dan kecepatan aliran sungai. Metode yang digunakan adalah pendekatan kuantitatif melalui pengambilan sampel tanah pada beberapa titik sepanjang 500 m dari Jembatan Putih Jl. Latamaccelling, serta uji laboratorium meliputi berat jenis tanah, analisa saringan, dan kadar air tanah, disertai pengukuran kecepatan aliran menggunakan current meter. Hasil pengujian menunjukkan bahwa sedimen yang terdapat di Sungai Ammasangan terdiri atas pasir, kerikil, dan tanah dengan berat jenis rata-rata berkisar antara 2,60–2,70 gr/cm³. Analisa saringan memperlihatkan gradasi butir sedimen dominan berupa pasir kasar hingga halus. Nilai kadar air tanah bervariasi antara 15%–35% tergantung lokasi pengambilan. Pengukuran lapangan menunjukkan kecepatan aliran sungai rata-rata sebesar ±0,63 m/s dengan debit aliran sekitar 2,5–3,0 m³/s. Dari hasil tersebut dapat disimpulkan bahwa sedimentasi Sungai Ammasangan cukup signifikan sehingga mempengaruhi kapasitas penampang sungai dan berpotensi meningkatkan risiko banjir. The objective of this study was to determine the characteristics of sediment and river flow velocity. The method used was a quantitative approach through soil sampling at several points along a 500-meter stretch from the White Bridge on Jl. Latamaccelling. Laboratory tests included soil specific gravity, sieve analysis, and soil water content, along with flow velocity measurements using a current meter. Test results indicated that the sediment in the Ammasangan River consists of sand, gravel, and soil with an average specific gravity ranging from 2.60–2.70 g/cm³. Sieve analysis revealed a dominant sediment grain gradation of coarse to fine sand. Soil water content varied between 15%–35% depending on the sampling location. Field measurements indicated an average river flow velocity of ±0.63 m/s with a flow rate of approximately 2.5–3.0 m³/s. From these results, it can be concluded that sedimentation in the Ammasangan River is significant enough to affect the river's cross-sectional capacity and potentially increase the risk of flooding.

Abstract

The accumulation of non performing financing in economic activities financed by banks can cause problems with the continuity of the bank's operations, if that exceeds certain limits will have potential to stop the bank's activities. This study aims to analyze the influence of bank's internal variables like  FDR, CAR, BOPO and bank external variables like macroeconomic indicators consisting of exchange rates, inflation and GDP (GDP) against non-Performing Financing (NPF) of Islamic Commercial Banks in Indonesia. The data used are monthly industrial time series of Sharia Commercial Banks (BUS) for the period June 2014 to December 2018 sourced from the Islamic Banking Statistics of the Financial Services Authority, the Central Bureau of Statistics (Badan Pusat Statistik) and Bank Indonesia and analyzed using multiple regression methods. The research implications explain the relationship between the internal variables of the bank company (FDR, CAR and BOPO) and macroeconomic variables (Inflation, Exchange and GDP) on the NPF of Islamic banks in Indonesia so that they can be used as input for the relevant authorities in making policies to suppress NPF at a low level. The variables used can provide an overview of the role of the implementation of sharia public bank governance and existing macroeconomic conditions so that it can produce policies and provisions in the field of sharia banking that are effective and on target. The results showed that the CAR variable had a significant effect on NPF with negative influence. Whereas FDR, BOPO, exchange rate, inflation and GDP have no influence on NPF BUS in IndonesiaKeywords: Non Performing Financing, Non Performing Loan, Islamic Commercial Bank, Indonesia.
