Abstract

Along with the growth in oil palm output, the amount of trash produced will also increase. Every palm oil mill is responsible for the disposal of liquid waste known as palm oil mill effluent (POME). POME includes very high levels of BOD and COD, which may hinder the development of microalgae. Before POME may be utilized as a medium for the growth and development of microalgae, a detailed investigation is required to establish the pretreatment measures necessary to reduce the BOD and COD levels. The purpose of this investigation of POME waste as a substrate for the growth and development of microalgae is to examine the POME processing procedure utilizing wild microalgae. The experimental technique consisted of adding POME and microalgae to the Erlemeyer in accordance with the required proportion. Research demonstrates that POME pond IV waste may be utilized as a substrate for the development of wild microalgae to lower POME waste BOD and COD levels. The variables used were the ratio of POME to microalgae volume and the quantity of nutrients supplied. Microalgae growth at a ratio of 1:4 produced the greatest decreases in BOD and COD, namely 61.66 ppm and 173.33 ppm from 110.6 ppm and 496.67 ppm, respectively. The impact of adding nutrient C at a concentration of 120 ppm led to the greatest decrease of BOD and COD, namely 65.33 ppm and 186.67 ppm, whereas adding nutrient N at a concentration of 40 ppm led to the greatest reduction of BOD and COD, namely 55.41 ppm and 158.33 ppm.

Abstract

Waste is an environmental problem that is still not fully resolved properly even though the resulting impact has a major effect on environmental pollution, especially solid medical waste. The purpose of this study was to assess the characteristics of solid medical waste at Undata Hospital based on its sources and types, calculate the average weight of solid medical waste generated per day, and evaluate the solid medical waste management system with sorting, packaging, collection and transportation modes in accordance with the criteria of Permen of Environment and Forestry Number 56 of 2015 and Permenkes Number 2 of 2023. This research uses a qualitative approach with a descriptive research type. This research was conducted in August-September 2023. The sampling technique in this study used Purposive Sampling, with 18 informants selected from each unit/room/installation at Undata Hospital, Palu City. Based on the results of the study, it was found that every day Undata Palu Hospital produces domestic waste as much as ± 270 kg / day. The results of the evaluation of the solid medical waste management system at Undata Palu Hospital show that basically it is quite effective but not optimal, because the storage process shows non-compliance with the guidelines for medical waste management by the Ministry of Health Number 2 of 2023, namely storage in TPS which should not be more than 2x24 hours, but in fact the accumulation of solid medical waste is stored for 1 month in the LB3 TPS due to delays in transportation by third parties. This causes a large amount of solid waste in the TPS so that the TPS becomes full and dangerous because the waste undergoes a process of decomposition and decay, which is harmful to the environment and human health. Undata Hospital needs to maximize the procurement of internal medical waste processing equipment (incineration equipment) which needs to be supported by the Environmental Agency and the relevant Health Office to prevent environmental pollution from medical activities.

Abstract

Thermization is a preheating procedure in which milk is heated at low temperatures for a brief time prior to further processing. It is often used in the dairy processing industry to make a variety of products, including pasteurized milk, milk powder, and cheese. Eliminating psychrophilic bacteria, avoiding milk spoiling, and halting the changes generated by lipase and protease enzymes are the objectives of this method. Despite the fact that thermization enhances the shelf life of milk, it may also result in sensory changes and the germination of B. cereus spores. The goal of the thermization method is to prepare milk for the upcoming processing stage, and the temperature and length of the process might vary. Thermization does not affect the flavor of milk or dairy products such as yogurt, but it may enhance the quality of cheese by decreasing the occurrence of stale and rancid flavors. The process may be carried out in a plate heat exchanger or as a pre-pasteurization treatment for raw milk to protect milk quality during lengthy storage in insulated silos.

Abstract

Moringa Oleifera leaves contain many phytochemical compounds, as the potential source of antioxidants. The leaves must be converted into dried form to extend the shelf life and prevent the nutritional qualities. The lack of a common sun-drying process for Moringa Oleifera leaves is dependent on the weather. But using convective dryers also requires high investment costs and results in very low energy efficiency. One potential option to enhance energy efficiency is lowering the humidity by dehumidification with zeolite. This research aims to evaluate the effect of drying temperature and the weight of adsorbent (zeolite) on drying kinetic and thermal efficiency of Moringa Oleifera leaves drying. Moringa Oleifera leaves were dried under different drying temperatures (30-70℃) and weight of zeolite (0-0.3 kg). The moisture content of Moringa Oleifera leaves and the input-output temperature was recorded to evaluate the moisture reduction and thermal efficiency. Results showed that the Page model can be used to predict the drying time. At the higher drying temperature and higher zeolite weight, moisture reduction and thermal efficiency increased. But the effect of zeolite is only significant in drying at temperatures below 50℃.

Abstract

Indus delta with its coastal zones is the most significant coastal environment in Pakistan for mangroves and associated ecosystems. Mangrove forests are important components for maintenance of ecosystems in severe environments. The purpose of the study is to assess the mangrove species' tolerance to salinity. Aegiceras corniculatum and Ceriops tagal (C. tagal) propagules were grown in pots with sandy soil and subirrigated with 25, and 50% nitrogen-fortified saltwater for this research. The propagules were procured from the Indus delta. We raised seedlings for six months as an experiment. Aegiceras corniculatum species behaved moderately in the greenhouse, whereas Ceriops tagal's growth maximum at a salinity of 50% seawater and declined as the salinity increased. Furthermore, Ceriops tagal a non-secretor, accumulated more sodium and chloride ions while severely restricting the availability of other ions. This species might therefore be used to repair intertidal ecosystems, which frequently get freshwater. During a six-month the experimental cultivation period, and measurements were taken of the seedlings' length, weight at planting, and number of leaves. Maximum growth was observed in 50% seawater, and as the salinity increased, it became worse. Three times a week, fresh water was provided to wash away the excess salt. It has been discovered that medium and large-sized propagules function better in a greenhouse environment than small-sized ones. In order for plant seeds to successfully reproduce, the environmental conditions in which they disseminate and settle must be suitable for them. For establishment and dissemination inside the greenhouse environment, the propagules of viviparous mangrove species appear optimal.

Abstract

The aim of this study is to determine the effect of neem leaves in preserving the mineral elements content of two tomato types from Sokoto state, Nigeria. Healthy, ripe and firm tomato fruits brought from Sokoto City, were selected, cleaned for this study. 5%, 10% and 25% by were prepared by dissolving respective 5g, 10g and 25g neem extracts in 9.5, 9.0 and 7.5 liters of distilled water respectively to preserve tomatoes. The experiment was laid in a completely randomized design. And elements, Na, K, Ca, Mg, and P were determined in the tomatoes after the experiment using atomic absorption spectroscopy. The levels of Na, K, Ca, and P in Daneka after preservation ranges are: 1.1-1.3(ppm), 2.1-2.3 (ppm), 1.0-1.3 (ppm), 0.30-0.34 (ppm), and 0.3200-0.3330 (ppm) respectively. The levels of Na, K, Ca, and P in UTC after preservation ranges are: 1.6-1.10 (ppm), 1.6-1.10 (ppm), 0.10-1.16 (ppm), 0.30-0.35 (ppm), and 0.9997-1.0998 (ppm) respectively; revealing an increasing trend of elemental contents of all the tomato cultivars with an increasing neem concentration. Thus, the neem leaves indicate the capacity to preserve a typical quality parameter of tomatoes, that is concentration of Na, K, Ca, and P elements at p < 0.05 significant level.

Abstract

The interaction between the addition of soybean oil and phycocyanin extract on the protein, fat, and solid non-fat content of pasteurized milk after a one-week storage period is highly important to investigate. Soybean oil is used to improve the quality of pasteurized milk, particularly its chemical quality, consisting of fat, protein, and Solid Non-Fat (SNF). Phycocyanin extract provides a source of protein, whereas soybean oil contains healthy fatty acids. Before the fresh milk is pasteurized, soybean oil and phycocyanin are added. The LTLT (Low Temperature Long Time) technique was used to pasteurize the milk at 63 °C for 30 minutes. After the pasteurization procedure was completed, the milk samples were refrigerated for one week at a temperature of 4 °C. Following the storage period, the chemical composition of pasteurized milk is examined. With the addition of soybean oil and phycocyanin extract, the protein content of milk rose, as shown by the findings. The sample T1 with a concentration of 0.45% soybean oil and 0.50% phycocyanin extract had the greatest amount of protein (3.58). The sample T2 with 0.45% soybean oil concentration and phycocyanin extract (1%) had the greatest fat content (6.4%). Adding soybean oil and phycocyanin extract enhanced the total SNF concentration. On the basis of the study conducted, it can be concluded that the addition of soybean oil and phycocyanin extract to pasteurized milk has an influence and interaction on the milk's protein, fat, and SNF content. The addition of soybean oil and phycocyanin extract to pasteurized milk held for one week may boost protein, fat, and SNF concentrations.
