An Assessment of Water Quality and Identification of Problems: A Case Study of Maritimepattu Divisional Secretariat, Northern Province

/in /by

The Maritimepattu Divisional Secretariat (DS), located in Sri Lanka’s dry zone, is underlain by Miocene limestone, which is considered to have aquifer properties favourable for groundwater storage and discharge. Given that groundwater serves as the primary water resource for domestic, industrial, and agricultural purposes, maintaining its quality is a significant concern. This paper aims to assess the water quality in the region, identify associated problems, and investigate potential causes and preventive measures. A purposive sampling method was employed to select six sample Grama Niladhari (GN) divisions. In addition, 100 questionnaires were administered, and 36 water samples were collected for the study. These water samples were tested based on eight major water quality parameters: Electrical Conductivity (EC), Salinity, pH, Total Dissolved Solids (TDS), Fluoride (F-), Nitrogen (N), Phosphorous (P), and Turbidity (Tn). Furthermore, secondary data were gathered from previous literature. Both primary and secondary data were analysed using Minitab and Geographic Information Systems (GIS). The measurements were then compared to the desirable limits set by the Sri Lanka Standards Institute (SLSI). This study revealed that the highest recorded values for EC, Salinity, pH, TDS, F-, N, P, and Tn were 2480 µS/cm, 1254 ppm, 8.6, 632 ppm, 1.1 ppm, 7,9 ppm, 3.8 ppm, and 36.7 NTU, respectively. These values exceed the standard limits set by the Sri Lanka Standards Institute (SLSI). The pollution in the area can be attributed to various factors, including topographical conditions, improper agricultural practices, inadequate sanitation methods, dumping sites, war activities, and industrial waste. As a result, these issues have led to serious health problems, reduced crop yields, insufficient drinking water, and the degradation of groundwater resources. Therefore, this study recommends the adoption of green agriculture practices, the installation of water treatment plants, the promotion of rainwater harvesting systems, and the enforcement of land and irrigation-related laws. Moreover, hazardous waste material must be disposed of at designated sites to protect water resources.

Oil & gas business is still attractive for investors. Today, they look carefully at company’s financial indicators (ROA, ROI, Profitability) and new indicator called “ESG” in making investment decision(Pedersen et al., 2021). PT.X, a developing national energy company with vision becoming world class, currently still rely on fossil energy as the backbone of its business. To finance its operations, PT.X opens up opportunities for investors to invest. To attract investors, PT.X is pursuing better ESG rating each year. In 2023 ESG score of PT. X is 20.7, 1st rank out of 61 O&G companies in the world (Morningstar Sustainalytics version). In competitive energy business post Covid-19 pandemic PT. X aware that they must improve its ESG score continuously. Several strategic goals have been set, one of it is Total Recordable Injury Rate / TRIR, a ratio of number of recordable incidents per total working hours in a year. Target is more challenging each year. TRIR 2024 was set 0.19. This number is much lower than the average TRIR achieved by IOGP members in 2020 that is 0.7. PT. X’s TRIR goal applies to all of its subsidiaries including PT. X-Y located in biggest O&G block East Kalimantan Indonesia. PT. X-Y operates big mature field ultimate with ultimate challenge to maintain oil and gas production from wells that decline naturally. PT. X-Y have planned massive work programs i.e: drilling ± 100 wells/year, ± 4000 wells intervention, and also several offshore platforms construction & installation projects. These activities involve many workers and very high risks. Workers’ safety culture is very important to support the achievement of this goal. Unfortunately, the results of surveys conducted several times by one of reputable university in Indonesia, PT. X-Y safety culture level has decreased from the Proactive to Calculative. To improve PT. X-Y should start by solving organization’s safety cultures’ issues. Also, with limited resources the company’s safety team believed they should focus on improving existing safety program called “TEMAN” rather than introducing new ones. OKR framework is used to manage these difficult objectives because it has superior principles and similarity with PT.X core value AKHLAK, i.e: align and connect team work, focus and commit to priorities, track for accountability. OKR method is successful helping big companies such as Intel, Google, IBM to achieve their stretch goals with minimal side effects / no side effects at all.

Modification of Rice Noodle Physical, Cooking Properties and Microstructure through Xanthan Gum and Moisture Control

/in /by

Noodles have been a staple dish in Asia since ancient times, taking numerous shapes and forms. Presentation, texture, eating quality, and cooking qualities are all factors that influence its quality. Noodles can be made using either traditional or extrusion methods. Pasta extruders are modern machines that create pasta in a variety of shapes. Xanthan gum is a hydrocolloid that enhances the physical properties of rice. Its functions include enhancing texture quality, increasing air binding ability, and stabilizing dough structure. The amount of xanthan gum used influences not just the physical properties of rice, but also the feed composition. The air feed content is a crucial factor influencing the flavor of noodles. Using a pasta extrusion machine, this study investigated the influence of xanthan gum (0%, 1%, 1.5%, and 2%) and feed moisture (35%, 40%, and 45%) on rice noodle characteristics. This study found that the optimum treatment was xanthan gum 1.5% and feed moisture 40%. This treatment has the following values: cooking time 5.83 minutes, cooking loss 5.95%, water absorption 274.12%, hardness 0.3887, adhesiveness = -0,0027 L = 75.51, a = -0.53 and b = 8.92.
