Abstract

Jalan Salokarajae merupakan jalan provinsi yang menghubungkan antara Kabupaten Enrekang dan Kabupaten Sidenreng Rappang. Ruas jalan ini memiliki lapisan perkerasan lentur dengan berbagai jenis kerusakan. Tujuan dari penelitian ini adalah untuk mengetahui kualitas lapisan perkerasan jalan menggunakan metode PCI. Sepanjang 3 km jalan dibagi menjadi 30 segmen dengan ukuran 100 x 5,5 m dan di evaluasi pengukuran dimensi, identifikasi jenis dan tingkat kerusakannya. Hasil penelitian yang dilaksanakan pada bulan Maret 2022 ini menunjukkan terdapat 7 macam kerusakan yang terjadi seperti retak kulit buaya sebesar 0,91 %, retak memanjang sebesar 3,30 %, lubang sebesar 1,73 %, kerusakan tepi sebesar 0,54 %, tambalan sebesar 32,04 %, pelepasan butiran sebesar 58,19 % dan amblas sebesar 3,30 %. Nilai rata-rata PCI sebesar 45 yang menunjukkan bahwa perkerasan jalan dalam kondisi cukup sehingga diperlukan adanya penanganan serius dari pemerintah untuk segera melakukan perbaikan.

Abstract

Irigasi Kalola merupakan jaringan irigasi yang terletak di Desa Anabanua, Kecamatan Maniangpajo, Kabupaten Wajo. Permasalahan kurangnya debit air disebabkan petani melakukan pemompaan di hulu sehingga banyak sawah yang mengalami kekurangan air di hilir. Tujuan dari penelitian ini untuk mengetahui kebutuhan air dan efisiensi saluran sekunder dan tersier. Penelitian ini menggunakan metode kuantitatif yaitu dapat dihitung atau diukur langsung yang dinyatakan dengan angka atau bilangan. Penelitian dilakukan pada bulan Maret – April 2022 dengan hasil yang menunjukkan bahwa kebutuhan air irigasi tidak terpenuhi karena kurangnya ketersediaan air pada saluran dan nilai efisiensi saluran sekunder dan tersier tidak sesuai Kriteria Perencanaan (KP-03) yaitu saluran sekunder 87,50% dan saluran tersier 80%.

Abstract

Dengan adanya kemajuan teknologi saat ini, proses stabilisasi tanah sudah dapat dilakukan dengan berbagai cara. Penelitian ini bertujuan untuk mengetahui pengaruh kapur dan abu batu sebagai bahan tambah dalam stabilisasi subgrade dan pengaruhnya terhadap nilai kualitas CBR Tugu Tunas Kelapa Kota Parepare. Dari hasil pengujian derajat kepadatan pada tanah asli sebesar 83,97%, kemudian naik sampai 87,35% pada penambahan abu batu 6% dan kapur 6%. Pada tes DCP, tanah asli diperoleh nilai CBR titik 1 sebesar 10,8%, titik 2 sebesar 10,4% dan titik 3 sebesar 8,7%. Pada penambahan kapur dan abu batu 2% diperoleh nilai CBR 13,9%, penambahan 4% diperoleh nilai CBR 14,8% dan penambahan 6% diperoleh nilai CBR 15,3%. Dari penambahan abu batu dan kapur nilai CBR akan semakin meningkat sehingga perlu dilakukan penelitian lebih lanjut.

Abstract

Jendral Ahmad Yani Km. 2 road is one of the land transportation accesses that connects between regions in improving the economy and standard of living of the community. This study aims to analyze the geometrics of road bends. The research method used is descriptive quantitative method of analysis using the standards of the Directorate of Highways. The results of the research from the geometric bend results that the road section includes a primary collector function class SCS type bend with provincial road status with type 2/2 UD. The existing geometric conditions of the road section are in accordance with the required standards where there is a vertical alignment of 8.1% and a stopping sight distance of 133.36m. Coordination of alignments that coincide does not obstruct visibility.

Abstract

Paving blocks are becoming more popular among consumers because they are environmentally friendly, can save groundwater, are easy to install and maintain, and have many shapes that add aesthetic value. This study aims to determine the difference of shells on the water absorption capacity of paving blocks and the strength of paving blocks. Experiments were conducted at the structure and materials laboratory of Muhammadiyah University of Parepare from August to October 2023 for this research method. The results showed that the water absorption of paving blocks was influenced by the addition of seashells. The water absorption values of the 0%, 5%, 10%, and 25% variations were 1.4 percent, 2 percent, 3.4 percent, and 3.7 percent for the 7-day treatment period; 0.6 percent, 1.7 percent, 2.4 percent, and 3.3 percent for the 14-day treatment period; and 1.3%, 2.8 percent, 3.0 percent, and 4.6 percent for the 28- day treatment period. According to the above results, the more clamshells added, the greater the water absorption. The compressive strength shows that the addition of clamshells affects the compressive strength of block paving. The compressive strength values were 23.841 Mpa, 9.365 Mpa, 21.587 Mpa, and 11.429 Mpa at the 28-day curing age, respectively. The more clamshells added, the lower the compressive strength.

Abstract

The use of rainwater as an alternative source of clean water is also very potential when applied in residential areas or residential areas. In Karunrung Village, Rappocini District, Makassar City, there is still a lack of adequate clean water supply, some people use shallow wells but in the event of a drought, the shallow wells experience drought. This study aims to find out how much discharge is the influence of rainwater treatment to meet the need for clean water in Anging Mammiri Housing. This study uses a descriptive qualitative research method. The results of the study show that the amount of potential rainwater discharge that can be produced into clean water needs is obtained from calculating the amount of rainwater that can be managed into clean water which amounts to 86,993.8 liters/day and the amount of clean water needed by the residents of Anging Mammiri which amounts to 51,750 liters/day so that rainwater treatment is able to meet the clean water needs of the community in Anging Mammiri Housing as much as 52% per day.
