Abstract

Daerah Labuhan Badas, Kabupaten Sumbawa, tersusun oleh material vulkanik yang memiliki karakteristik geologi dan geoteknik beragam sehingga perlu dikaji sebagai dasar perencanaan lereng yang aman. Penelitian ini bertujuan untuk menganalisis karakteristik litologi dan parameter geoteknik material vulkanik serta mengevaluasi pengaruhnya terhadap perencanaan lereng. Metode penelitian meliputi pemetaan geologi, penggalian test pit, pengambilan sampel, dan pengujian laboratorium yang mencakup analisis gradasi butiran, berat isi, berat jenis, batas Atterberg, kadar air, serta California Bearing Ratio (CBR). Hasil penelitian menunjukkan bahwa litologi daerah penelitian didominasi oleh breksi vulkanik, endapan pasir vulkanik, dan lapisan tanah penutup (top soil). Nilai berat jenis berkisar antara 2,557–2,630 g/cm³, indeks plastisitas 8,66–11,82%, dan nilai CBR 11,50–13,70%, yang menunjukkan material memiliki plastisitas rendah hingga sedang serta memenuhi persyaratan daya dukung tanah dasar. Karakteristik litologi dan parameter geoteknik tersebut menunjukkan bahwa material vulkanik di daerah penelitian memiliki potensi yang baik untuk perencanaan lereng, dengan tetap mempertimbangkan kondisi geologi dan penerapan desain lereng yang sesuai guna menjamin kestabilan jangka panjang.

Abstract

This study aimed to analyze the management of a subcutaneous abscess in a Shih Tzu dog, including identification of the causative agent, antibiotic sensitivity testing, and evaluation of the clinical therapeutic response. The case was managed at ZZ Petcare Clinic using a systematic approach consisting of anamnesis, physical examination, ultrasonography (USG), aseptic collection of pus samples, local drainage, abscess cavity irrigation, and follow-up treatment with broad-spectrum antibiotics, amoxicillin, vitamin B complex, and topical antibiotics. Pus samples were analyzed in the laboratory for bacterial isolation and identification using biochemical tests, while hematological examination was performed to assess the patient’s systemic status. Ultrasonographic examination identified an accumulation of purulent fluid with an approximate diameter of 7 cm, accompanied by an inflammatory response in the subcutaneous tissue. Laboratory analysis of the pus revealed that the causative agent of the abscess was Staphylococcus aureus, with antibiotic susceptibility testing showing sensitivity to ciprofloxacin, intermediate susceptibility to amoxicillin, and resistance to penicillin and ceftriaxone. Initial hematological examination indicated leukocytosis and mild inflammatory anemia, with WBC and RBC values of 20.4 × 10⁹/L and 5.05 × 10⁹/L, respectively. Following therapy, the patient’s condition improved, as evidenced by normalization of white blood cell and red blood cell parameters, with WBC and RBC values of 7.8 × 10⁹/L and 7.96 × 10⁹/L, respectively. The therapy administered was sufficiently effective, as indicated by clinical improvement within five days after treatment. This study emphasizes the importance of combining local drainage procedures, appropriate wound care, and antibiotic selection based on susceptibility testing in controlling infection and promoting patient recovery.
