Abstract

Ammonia (NH3) is one of the impurities in salt-producing water, which is often found in the traditional salt ponds of the Madurese. The purpose of this study was to determine the concentration of ammonia contamination as an impurity in salt production process water from raw water, reservoir ponds, evaporator ponds to geomembrane crystallizer ponds when salt production takes place in the salt ponds of Tanjungan Village, Bangkalan Regency. Determination of ammonia concentration using the phenate method based on SNI 06-6989.30-2005 with a spectrophotometer reading tool (UV-2700 Serial No. A11674900027) at a wavelength of 420 nm. The average concentration of ammonia as an impurity in raw materials in traditional pond ponds in Tajungan village, namely raw water is 2.31±0.24 mg/L, reservoir ponds are 2.56±0.57 mg/L, evaporator ponds are 2, 39±0.84 mg/L and the geomembrane crystallizer ponds are 1.37±0.09 mg/L. The highest average ammonia concentration was found in the reservoir ponds raw saltwater sample, while the lowest concentration was found in the geomembrane crystallizer ponds sample. The high average ammonia concentration in the salt ponds of Tajungan Village, Bangkalan Regency indicates that all raw saltwater in these ponds is contaminated with ammonia. The high concentration of ammonia in the salt ponds may be due to the entry of household waste. Keywords: (NH3), raw water, reservoir ponds, evaporation ponds, geomembrane crystallizer ponds

Abstract

ABSTRAKKelompok bakteri slight halofilik dapat ditemukan di air laut pada kolam peminihan yang menjadi bahan baku utama dalam pembuatan garam di Pamekasan-Madura. Tujuan penelitian ini adalah untuk mengetahui karakteristik biokimia isolat bakteri halofilik yang di isolasi dari kolam peminihan pada tambak garam rakyat di Pamekasan-Madura. Metode yang digunakan dalam penelitian ini yaitu pengujian biokimia bakteri halofilik meliputi pewarnaan Gram, uji indol, katalase, dan oksidase, uji metil red, uji Voges Proskauer, asimilasi citrat, dan uji pemanfaatan sumber karbon. 3 isolat berhasil ditumbuhkan dalam media padat halophile menggunakan kadar garam sebesar 1% dengan kode P.P.1, P.P.2 dan P.P.3. Hasil uji indol ketiga isolat bakteri halofilik P.1, P.2 dan P3 menunjukkan hasil uji indol negatif.  Sumber karbon yang digunakan bakteri tersebut diantaranya glukosa, sukrosa dan mallosa dengan uji O/F, fermentative untuk isolat P.P.1 dan P.P.3 sedangkan non fermentatif untuk isolate P.P.2. Uji MR-VP menunjukkan hasil negatif untuk ke tiga isolat tersebut. Uji katalase dan uji oksidasi masing-masing isolat menunjukkan hasil positif, sehingga isolat P.P.1, P.P.2 dan P.P.3 termasuk bakteri aerob. Kata kunci: slight halofilik, kolam peminihan, uji biokimiaABSTRACTA diverse group of slight halophilic bacteria can be found in saline enviroment such purification water of traditional salt production Pamekasan-Madura. The existence of slight halophilic microbial communities from purification water of traditional salt production have not been used optimally. The aim of this study was biochemical characterization of the halophilic bacteria isolated from traditional salt production Pamekasan- Madura. The biochemical characterization were done using standart methodes which included indole test, catalase and oxidase activities, methyl red test, Voges-Proskauer (VP) test, citrate utilization test and carbohydrates utilisation . 3 isolates, P.P.1, P.P.2 and P.P.3 were successfully grown in halophile agar plates containing 2% of total salt. All of these isolates were negative for indole production and MR-VP test, but were positive for catalase and oxidase activities.  The carbon sources used by these isolates included glucose, sucrose and mallose with the O/F test was fermentative for P.P.1 and P.P.3 while non-fermentative for P.P.2. All of these isolates were identified as aerob bacteria.Keyword: slight halophilic, purification water, biochemical characterization

Abstract

Halophiles are bacteria that require specific salt concentrations to survive, while halotolerants are bacteria that grow in the absence of salt and in the presence of high salt concentrations. Both halophiles and halotolerant bacteria have potential biotechnological applications. The aim of this study was to isolate moderate halophiles and halotolerant bacteria from the raw water of salt ponds at Trunojoyo Madura University and to determine their morphological and biochemical characteristics. Four halophilic bacterial isolates with codes AB.1.2, AB.2.4, AB.2.5, and AB.3.6, and two isolates of halotolerant bacteria with codes AB.1.1 and AB.2.3, were obtained. All isolates were coccus shaped, and most of the isolates were gram-negative. Three isolates were identified as aerobic bacteria based on catalase and oxidase tests. Only halotolerant bacteria AB.1.1 and AB.2.3, showed positive results in the citrate utilization test, while halophiles AB1.2, AB.2.5, and AB.3.6, showed positive results in the urease test. All isolates, both halophiles and halotolerant, were able to utilize sucrose, glucose, mannitol, and maltose.
