Abstract

Liquefied Petroleum Gas (LPG) is a major energy source in Indonesia’s household, commercial, and industrial sectors; therefore, its quality must be controlled to ensure combustion performance and user safety. This study evaluated the hydrocarbon composition and ethyl mercaptan content of LPG samples and their conformity with the Decree of the Director General of Oil and Gas No. 116.K/10/DJM/2020. Five mixed-LPG samples were analysed at the Gas Composition Laboratory of BBPMGB LEMIGAS. Hydrocarbon composition (C₂–C₅) was determined by Gas Chromatography–Flame Ionization Detector (GC-FID) according to ASTM D2163, while ethyl mercaptan content was measured using a length-of-stain gas detector tube following ASTM D5305. The GC-FID system was verified using a Certified Reference Material (CRM), and all thirteen measured components were within the CRM acceptance ranges, confirming instrument suitability. Samples 1 and 2 complied with the C₂ limit (max 0.80 %vol), while Samples 3, 4, and 5 exceeded the limit with values of 0.9300, 0.8510, and 1.0281 %vol, respectively. All samples met the C₃+C₄ and C₅+ requirements. Ethyl mercaptan contents of Samples 1–4 (1.8–3.9 lb/10,000 AG) met the minimum requirement, whereas Sample 5 did not (0.96 lb/10,000 AG). Overall, only Samples 1 and 2 satisfied all tested parameters, indicating that LPG quality evaluation requires multiple quality parameters.

Abstract

Achieving Sustainable Development Goal (SDG) 6 on access to clean water and adequate sanitation requires effective wastewater management, including from healthcare facilities such as hospitals. Hospitals have the potential to generate wastewater containing organic and inorganic contaminants, as well as pathogenic microorganisms, which can pose a risk of environmental pollution if not properly treated. This study aims to evaluate the quality of wastewater produced by a hospital in Central Lampung Regency based on the quality standard parameters stipulated in the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 68 of 2016. The parameters tested include pH, Total Suspended Solid (TSS), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD₅), fatty oil, and total ammonia. The test results showed that the pH value was 6.98; TSS 3.00 mg/L; COD 43.28 mg O₂/L; BOD₅ 1.22 mg/L; fatty oil 0.3 mg/L; and total ammonia 0.191 mg/L. All parameters were well below the maximum quality limits for hospital wastewater. These findings indicate that the hospital's wastewater treatment plant (WWTP) is functioning correctly, resulting in safe wastewater and no potential environmental pollution. This evaluation supports efforts to meet SDG indicator 6.3, which focuses on improving wastewater treatment and reducing water pollution

Abstract

Petroleum remains a key energy source in Indonesia, driving continuous drilling to find new oil reserves. Drilling operations rely on potassium chloride (KCl) as a supporting chemical, functioning to stabilize rock formations, reduce pipe corrosion, and control wellbore failure. KCl used for drilling must meet quality standards set by Scomi Oiltools' Drilling Fluid Engineering handbook. This Field Work Practice, conducted at LEMIGAS, Jakarta, evaluated the density, turbidity, and chloride content of eleven KCl samples from three companies against Scomi Oiltools standards. Density was measured using an Automatic Density Analyzer (ASTM C604); turbidity via Direct Reading Spectrophotometer (ASTM D7315-17); and chloride content through Mohr argentometric titration (ASTM D512-04; SNI 6989.19:2009). Results showed densities of 1.9–2.9 g/mL, exceeding the ideal 1.0–1.16 g/mL range, and chloride levels of 1,950–2,060 ppm, far below the required minimum of 4,700 ppm. Turbidity ranged from 1–80 FTU, with all but one sample meeting the standard below 20 FTU. Thus, while turbidity generally complied, density and chloride content of all samples failed to meet Scomi Oiltools standards, highlighting the need for rigorous quality testing before selecting KCl for drilling use.
