Abstract

Each year plastic production worldwide has increased. Approximately 10% of the production of plastic will lead to the sea. This plastic is degraded to be a small particle size < 5mm called microplastic. The river is the main route of entry of plastic from land to the sea. Sayung River is a river that has the potential to be contaminated with microplastics around which it is used as a location for the cultivation of various fisheries commodities including Pernaviridis, Penaeus monodon, and Lates calcarifer. The study aims to determine the number and type of microplastic in Penaeus monodon, Pernaviridis, and Lates calcarifer. Samples were taken from three different stations in the coverage area. Microplastic abundance analysis by isolating microplastic on each sample. Isolation samples of Pernaviridis, Penaeus monodon, and Lates calcarifer are done by dissolving the sample in a solution of 10% KOH was allowed for 24 hours at a temperature of 60 oC and observed under a binocular microscope. Founded types of microplastic are fiber, fragments, pellets, and films on Pernaviridis, Penaeus monodon, and Lates calcarifer. Pernaviridis found on many types of films, in Penaeusmonodon are the most prevalent types of fragments and the Lates calcarifer most common types of fiber. Pellet type is the least kind found in Pernaviridis and Penaeus monodon. Based on the age when taken, Penaeus monodon is the commodity that has the most potential to be contaminated with microplastic while based on the number of particles found in Lates calcarifer is the commodity with the most potential to be contaminated with microplastic.

Abstract

Cellulase is a very important enzyme for ethanol production from lignocellulose and others. Bagasse is very good to be chosen as lignocellulosic material for cellulase production because it is cheap and already available in a huge amount. Solid-state fermentation has advantages than submerged fermentation because of its higher yield and activity. Cellulase production using solid-state fermentation has been researched by many people, but for different substrate, different pretreatment and different fungi producer, it is likely to have a different condition. It is very important to perform specific study to optimize cellulase production with specific substrate and specific fungi which available in Indonesia. Because large amount of fungi strains available so it is wise full if they are screened using effective and efficient methods. This research is started by initial screening of three strain of Trichoderma reesei and five strain of Aspergillus niger using Congo red dye staining on CMC agar plate. It is shown that a strain of Trichoderma reesei and two strains of Aspergillus niger has better activity than the others. Further screening is performed by conducting solid-state fermentation using bagasse by three best strains for five days. The activity of the cellulase is measured every 24-hour using Ghose method by dinitrosalicylic acid as reagent. The highest activity is shown by A.niger ITBCC L74 on third day at 0.525 Unit/gram

Abstract

Tofu waste water is still being a significant issue in Indonesia owing to its level of BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand) (Chemical Oxygen Demand). However, this waste also includes significant ammonia (230 mg/L) which is needed for microalgae development. Microalgae are photosynthetic microorganism which need nitrogen supply for their development. Among others, microalgae Botryococcus braunii is the one with large oil amount within their cells (25 – 75 %). This study was meant to examine the usage of tofu whey for culture medium for algae development. The experiment was done by adjustment of whey volume (5-20 %) in fresh medium and algal biomass was continually measured. The findings revealed that Botryococcus braunii obtained optimum growth in 10 % volume with biomass generated at 2.4 g/L and 0,8716 g/L of lipid production. At this circumstance, COD might be lowered up to 83.33 %.

Abstract

POME is a kind of liquid waste produced by the crude palm oil industry. POME was not treated adequately, resulting in an issue for the environment owing to excessive levels of COD and BOD. Algae is a kind of bio-absorbent that may neutralize contaminants in liquid waste. Microalgae need carbon, nitrogen, and phosphorus-containing ingredients to flourish. These nutrients are necessary for photosynthetic carbon sources to be converted into biomass. POME includes a high concentration of C, N, and P; hence this research aims to investigate the potential of POME as a medium for the development of algae such as Spirulina, Nannochloropsis, and Chlorella. The experiment was carried out by varying the nutrients, water type, and time of nutrient feeding. Urea and sodium bicarbonate were the nutrition. Preparing the medium, culturing the microalgae, assessing biomass, counting the algae cells, and creating a calibration curve were the procedures in the experiment. The findings revealed that POME is the best medium for microalgae, that Spirulina grows better in POME than Chlorella and Nannochloropsis, and that providing nutrients every 2 days was better than introducing nutrients at the beginning and without adding nutrients.

Abstract

Microalgae have an important role as a source of biomass in producing energy. One type of microalgae that has the potential to be developed is Chlorella vulgaris. Several factors that affect the growth and biomass production of Chlorella vulgaris microalgae are color temperature and light intensity because they play an important role in the photosynthesis process. This study aims to influence the effect of light and color temperature and optimize these parameters using Response Surface Methodology (RSM). Two independent variables were varied: light intensity 200, 400, 600, 800, 1000 lux and color temperature 3000, 4000, 5000, and 6000 K. The results showed that the average value of Chlorella vulgaris growth was higher along with higher light intensity. At a color temperature of 4000 K, the highest biomass yield and the most negligible biomass production were found at 6000 K. At a color temperature of 4000 K, it is feasible to apply it as an alternative lighting source in the production of Chlorella vulgaris. The combination of light intensity and color temperature shows that the specific growth rate and doubling time have opposite trends where high values produce low values and vice versa. Growth in dark conditions, the specific growth rate was 0.0026 day-1, and the optimal light intensity at 600 lux treatment. ANOVA evaluation showed that color temperature greatly affected growth. Based on the optimization, the optimal specific growth rate of 00751day-1 with the conditions of light intensity and color temperature of 556 lux and 4152 K, respectively.

Abstract

In the development of phytoremediation this method can be simulated quite concisely and precisely. Simulations are carried out to predict plant behavior towards several different treatments, for example plant species, also types and concentrations of contaminants. In this study a dynamic model of phytoremediation has been made using sunflower plants and 134Cs and 60Co radionuclides. This study was developed by mimicking the interaction of soil and plants to be simulated into Phytoremediation Dynamic Model (PDM). Diverse mathematical algorithms implemented to characterize phytoremediation, systems such as differential equation, statistical correlation, and dynamic system approach. The error value obtained is different for each contaminant for each variation in concentration, which ranges from 0,0006-0,6349 for 134Cs contaminants and 0,0089-0,4157 for 60Co contaminants. The error value is quite small, and the overall simulation data has approached the experimental data. Factors that influence the results of calculated data include saturation point values, as well as the absorption rate of each part of the plant obtained from calculations and estimates. This model has proven to be able to mimic plant responses to contaminants

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.

Abstract

Indonesia and Malaysia are recognized as the world's leading producers of palm oil. Along with the growth of the palm oil industry in Indonesia, the amount of Palm Oil Mill Effluent has increased. Palm Oil Mill Effluent (POME) is a liquid byproduct of the palm oil production process. POME has been treated using aerobic and anaerobic ponds to lower Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels, but it still includes nutrients like as C,N,P that are beneficial to the development of microalgae. On this study, Spirulina platensis was grown in POME medium with 20%, 40%, and 60% V. concentrations. Every two days, the nutrients Urea, NaHCO3, and TSP were administered. Seven days of aeration and 24-hour lights are used throughout the cultivation phase. The results indicate that POME with a 20 % concentration is the optimal medium for plant growth. Add 25 ppm Urea, 50 ppm TSP, and 200 ppm NaHCO3 for the optimal nutritional composition. At the same treatment on various medium, the highest growth rate of Spirulina platensis is determined to be µ = 0.128% per day, with an optical density of 0.648. Carbon reductions range from 83.03 % to 84.10 %, while Nitrogen savings range from 78 % to 79.55 % when POME is used as a growing medium. This study also shown that the C, N, and P concentrations of POME fall by 93 to 98 %, 99 to 99.5 %, and 92 to 97 %, respectively.

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.
