Abstract

Clays and silts have the low strength compressive. Clay is a kind of fine grain soil that has a low bearing capacity and very sensitive to changes in water content. To improve soil conditions then soil reinforcement is done by using lime substance. The clay soil sample is a type of high plasticity clay that taken from Rawa Sragi- Jabung- East Lampung district and then the silt soil sample is taken from Yosumulyo-East Metro- Metro City. Based on previous experiments, that soil is included in soft clay and high plasticity category. Based on Unified Soil Clasification (USCS), clay belong to CL category, While silts belong to Cl-ML category. In unconfined compressive strength test, clays and silts with variation of curing time and unsoaked condition, soil with hydrated lime mixtured with modified proctor compacted, for clays,Qu value increased with the addition of lime content.  It get Qu optimum value increased when it has 12% hydrated lime content, 28 days of curing time. For silts Qu optimum value inscreased when it has 12% hydrated lime content and 28 days of curing time. Hydrated lime adding could inscred unconfined compressive strength but with longer curing time duration (28 days). Because the greater Qu soil value is the greater soil bearing capacity.Keywords: Hydrated Lime, Clay, Silt, Unconfined Compressive Strength, Soil Bearing Capacity

Abstract

Penelitian ini dilakukan untuk memberikan informasi dan gambaran umum kepada masyarakat tentang air tanah yang ada dengan cara menginventarisasi, mengeksploitasi, mengeksplorasi dan konservasi air tanah di Kota Bandar Lampung. Studi ini menggunakan program Geographic Information System (GIS) yang didukung dengan data sekunder berupa peta Bandar Lampung, data air tanah serta data curah hujan. Dalam penelitian ini dilakukan digitasi terhadap peta yang terdiri dari peta kondisi eksisting Bandar Lampung yang selanjutnya dioverlay dengan titik lokasi sumur bor menggunakan program GIS. Selain proses digitasi, dilakukan pula analisa neraca air tanah yakni antara tinggi air pengambilan sumur bor dengan tinggi hujan yang terinfiltrasi. Hasil dari penelitian didapatkan nilai keseimbangan air di tiap zona infiltrasi pada tahun 2006 yakni untuk zona infiltrasi <1.10-2 cm/detik selisihnya sebesar 7,909 m/tahun, zona infiltrasi antara 1.10-2 - 2.10-2 cm/detik selisih 7,896 m/tahun dan zona infiltrasi > 2.10-2 cm/detik 7,881 m/tahun. Jika diasumsikan setiap tahun mengalami peningkatan jumlah sumur sebesar 10% maka pada tahun 2016, untuk zona infiltrasi <1.10-2 cm/detik selisihnya sebesar 7,896 m/tahun, zona infiltrasi antara 1.10-2 - 2.10-2 cm/detik selisih 7,863 m/tahun dan zona infiltrasi >2.10-2 m/detik 7,823 m/tahun. Dari hasil analisa tersebut bisa disimpulkan pada tahun 2016 air tanah masih mencukupi untuk kebutuhan Kota Bandar Lampung, namun jika di lanjutkan sampai tahun 2079 kemungkinan akan mengalami krisis air tanah.Kata kunci : air tanah, neraca air, Geographics Information System (GIS)

Abstract

Abstrak Beton adalah bahan konstruksi yang paling banyak digunakan untuk bangunan sipil dikarenakan memiliki beberapa kelebihan. Kelemahan pada struktur beton yaitu mempunyai kuat tarik yang rendah dan bersifat getas (brittle) sehingga beton diberi tulangan baja sebagai bahan alternatifnya. Pada penelitian ini, campuran beton diberi bahan tambah serat bendrat berkait.  Penambahan ini dilakukan untuk mengetahui pengaruh serat bendrat berkait terhadap kuat tekan, tarik belah dan kuat lentur pada beton mutu normal dengan variasi kadar serat 0%, 0,75%, 1,0% dan 1,25% dengan panjang serat 60 mm dan diameter 1 mm. Benda uji kuat tekan dan tarik belah berupa silinder dengan diameter 15 cm dan tinggi 30 cm berjumlah 24 buah dan benda uji kuat lentur berupa balok dengan panjang 60 cm, lebar 15 cm dan tinggi 15 cm sebanyak 12 buah. Pengujian dilakukan setelah 28 hari. Kuat tekan, tarik belah dan kuat lentur pada beton meningkat setelah diberi penambahan serat kawat bendrat berkait. Peningkatan optimum terjadi pada variasi kadar serat 0,75% dengan hasil berturut-turut sebesar 35,9336 MPa, 3,9848 MPa, dan 8,9380 MPa. Semakin banyak variasi kadar serat akan menyebabkan sulitnya pergerakan agregat sehingga semakin besar kemungkinan terjadi balling effect pada saat pengerjaan beton. Kata kunci : kawat bendrat, kuat tekan, tarik belah, kuat lentur.
