Abstract

Smaller size plastics known as microplastics are harmful for marine biota as well as humans. One of the common methods for the removal of microplastics from water is coagulation. Chicken eggshells and chitosan are two natural ingredients which contain useful content for the coagulation process. Therefore, this paper describes the effect of concentration of eggshells and chitosan as coagulants in the separation of microplastic from water using RSM (Response Surface Methodology). The effect of tannic acid concentration as coagulation aid was also analyzed in this paper. The coagulants were varied with concentration of 1.5-8.5 g/100 mL and tannic acid concentration was 3-17 mg/100 mL. The result of this study showed coagulation with the highest efficiency occurred when 8.5 g/100 mL of chicken eggshell coagulant (89.14%) and 10 g/100 mL chitosan coagulant (75.67%) was added. Optimum operation occurred after the addition of coagulant aid in the amount of 7 mg/100 mL with chicken eggshell and 15 mg/100 mL with chitosan.

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

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

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

The study focuses on malnutrition. Dietary intake influences malnutrition. Indonesians choose dry noodles due of their portability. Dry noodles often include more carbohydrates than protein; consequently, the addition of Spirulina platensis may increase their protein level while de-creasing their carbohydrate load. This research evaluated the levels of protein, fat, water, and ash in dry noodles before and after supplementation with spirulina platensis. 1% and 2% of the fixed variable weight of Spirulina platensis were used. Included in analyses are protein, fat, water, and ash. Variation I (1%) results protein of 15.79%, whereas Variation II (2%) has 28.21%. Variation I (1%) have 13.07% moisture, whereas Variation II (2%) has 13,15%. Variation I (1%) contain 0.233% fat compared to variation II (2%) of 0.223%. Variation I (1%) had 1.445% ash content, whereas Variation II (2%), contained 2% ash. The nutritional value of Grade II or dried noodles with Spirulina platensis conforms to Indonesian National Standard 8217-2015. Spirulina platensis increases the pro-tein content of dry noodles when added. According to SNI 8217-2015 grade II, the addition of spir-ulina to dried noodles improved their protein, water, ash, and fat content. The nutritious content of dried noodles was improved by the inclusion of Spirulina platensis.

Abstract

The need of renewable energy is paramount important as it is expected to replace fossil energy. One of renewable energy commonly used for rural area is biomass-based energy. Biogas is a biomass-based energy where organic materials are converted to methane gas via anaerobic digestion process. The limitations of mono-feedstock biogas are instability digestion process, low yield biogas produced and require readjusting C/N ratio, therefore co-digestion process was proposed to overcome these problems. This study aims to investigate the feasibility of anaerobic co-digestion of a mixture of cattle manure and bagasse residue in different weight ratio combinations. Biogas was generated by anaerobic digestion using a mixed substrate composed of a combination of weight ratios of bagasse:cattle manure (1:5, 1:2, 1:1, and 3:1). The kinetic analysis was evaluated by fitting Gompertz and Logistic model to experimental data of cumulative biogas. The result showed that the combination of 1:5 ratio of bagasse waste to cattle manure obtained the best biogas yield with cumulative biogas at 31,000 mL. The kinetic model of Gompertz and Logistic were able to predict the maximum cumulative biogas at ratio of 1:5 (cattle: bagasse) at 31,157.66 mL and 30,112.12 mL, respectively. The other predictions of kinetic parameters were maximum biogas production rate (Rm)= 1,720.45 mL/day and 1,652.31 mL/day for Gompertz and Logistic model, respectively. Lag periods were obtained at 2.403 day and 2.612 day for Gompertz and Logistic model, respectively. The potential power generation of 338.71 Watt has been estimated from biogas. This research has proven a positive feasibility of co-digestion of two feed-stocks (cattle manure and bagasse) for biogas production.

Abstract

Within 20 years, Indonesia should find another energy alternative to substitutecurrent fossil oil. Current use of renewable energy is only 5% and need to be improved up to 17%of our energy mix program. Even though, most of the area in Indonesia is covered by sea, howeverthe utilization of microalgae as biofuel production is still limited. The biodiesel from currentsources (Jatropha, palm oil, and sorghum) is still not able to cover all the needs if the fossil oilcannot be explored anymore. In this paper, the potency of microalgae in Indonesia was analysed asthe new potential of energy (biodiesel) sources.

Abstract

Renewable energy is essential and vital aspect for development in Indonesia especially less oil reserve for coming 15 years. Biodiesel has received much attention as renewable energy in recent years. One of potential biodiesel is produced from microalgae. Due to high content of nutrients in Palm Oil Mill Effluent (POME), this waste is a potential for nutrient growth for microalgae. Chlorella is one of high potential for biodiesel since it has high lipid content (20-30%). The objective of the research is to determine growth rate and biomass productivity in Chlorella Sp cultured in POME. Chlorella Sp was cultured in 20%, 50%, 70% POME using urea concentration 0.1gr/L (low nitrogen source) and 1gr/l (high nitrogen source) at flask disk, pH 6.8-7.2; aerated using aquarium pump and fluorescence lamp 3000-6000 lux as light. Medium was measured using spectrophotometer Optima Sp-300 OD at 680 wave length in 15 days to calculate specific growth rate. At end of cultivation, Chlorella sp was filtered and measured as dry weight. Result indicated that Chlorella sp at 50% POME 1gr/L urea showed higher specific growth rate (0.066/day). Factor affecting growth rate of microalgae is CNP ratio, POME concentration, and urea concentration.

Abstract

Renewable energies have many advantages and their importance is rising owing to gravely mounting concerns for environmental issues and lack of fossil fuels in the future. Solar energy, well acknowledged as an inexhaustible source of energy, is developing dramatically for different purposes such as desalination and electricity generation. Appropriate solar power plant is very important factor for power generation due to its cost and other constraints. The applied technology is as important as the solar power plants location.  In this paper, a wide variety multi criteria decision making (MCDM) methods, investigated by various researchers, are presented to obtain effective criteria in selecting solar plants sites and solar plants technologies. There is not any comprehensive research providing all required criteria for decision making for site and technology selection. Based on the reviewed researches, weight of each criterion depends on many factors such as region, economy, accessibility, power network, maintenance costs, operating costs, etc. The important criteria for site selection are represented and investigated thoroughly in this review paper.© 2019.
