Abstract

Pencemaran air di ekosistem sungai banyak disebabkan oleh penggunaan deterjen dengan surfaktan anionik Linear Alkylbenzen Sulfonat (LAS). Komunitas bakteri pembentuk biofilm indegenous sungai tercemar deterjen diketahui memiliki kemampuan mendegradasi LAS. Tujuan penelitian ini untuk mempelajari dinamika dan diversitas komunitas bakteri pembentuk biofilm di ekosistem sungai serta potensinya dalam mendegradasi LAS. Penelitian meliputi isolasi bakteri dari sedimen sungai dengan metode pour plate dan uji potensi biodegradasi dalam sistem biakan kontinyu. Konsorsium isolat-isolat bakteri hasil isolasi diuji potensinya dalam mendegradasi LAS dalam media mineral sederhana yang mengandung 20 mg/L LAS dengan penambahan  sedimen batu sebagai substrat  dan perlakuan debit 50 dan 70 mL/jam. Densitas komunitas bakteri pendegradasi LAS dari bulan Desember 2012 hingga Februari 2013 relatif sama yaitu antara 19,7x104 cfu/g – 28,9x104 cfu/g, dengan indeks diversitas kurang dari 0,4. Konsorsium bakteri pada perlakuan debit 50 dan 70 mL/jam secara berturutan dapat mendegradasi LAS sebesar 51,23 % dan 76 % dengan waktu inkubasi 24 jam.  Didapatkan enam isolat bakteri pendegradasi LAS berdasarkan karakter fenotip berbeda spesies dengan nilai similaritas 51 %.   Kata kunci: bakteri, biofilm, degradasi, dinamika komunitas, LAS

Abstract

Background: Syphilis or king lion disease is a sexually transmitted infection (STI) caused by the Treponema Pallidium bacteria. This disease begins with a painless sore, usually found on the genitals, rectum or mouth. Based on data from the Central Java Department, there were 368 cases of syphilis throughout 2024, Tegal Regency, which is a city in Central Java, contributed 4 cases of syphilis, 2 of which were in pregnant women who underwent examination at Kardinah Regional Hospital. Objective: The purpose of this study was to provide care and management of childbirth cases with reactive syphilis at Kardinah Regional Hospital according to standards. Research Method: The method in this study used a descriptive qualitative method with a case study approach through subjective, objective, assessment and planning elements. Data were collected through observation, in-depth interviews, physical and supporting examinations, KIA books, and medical records. The main informants were determined by purposive sampling technique, namely mothers giving birth with reactive syphilis who were giving birth at Kardinah Regional Hospital, while additional informants were husbands, families, midwives in the VK room and obstetricians. Results: Based on the care and management of childbirth with reactive syphilis cases, there was no significant difference in the assistance of normal vaginal delivery provided there were no vaginal lesions and scabs on the body or canker sores in the mouth or lips.
