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

Wonosobo regency had many small and medium industries which produced carica fruit into candied carica. In the process of making candied carica by using simple technology, there tented to be inefficient in the use of materials, energy and water. It raised the amount of waste which can cause economic loss and environmental. The implementation could be used as one of the efforts to improve efficiency is cleaner production. This study aimed to identify the process of inefficiencies at each stage in the process of production and to provide alternative opportunities of applying cleaner production in the process of making candied carica. The methods were the observation, direct measurement and interview. The results showed the alternative opportunities of applying cleaner production that uses container vessel while charging syrup in the packaging process and the filtering process results boiling syrup; the application of operational standards of production use of tools and materials; application of good housekeeping; the separation between the solid and liquid waste; reuse used water from sinks, leather waste utilization for composting. The benefits of economic and environmental that derived from the application of cleaner production is the use of container vessel in the packaging process and filtered the boiled syrup IDR. 1,200,000 savings/ month and reduced liquid waste as much as 240 liters/ month. Reuse of washing water used could save IDR. 380,424/ month and reduce liquid waste as much as 110.268 liters / month. Utilization of the skin as compost obtained profits IDR. 2,220,000/ month and reduced solid waste 3,600 kg/ month. Thus, the implementation of cleaner production improved economic and environmental benefits of reduced waste formation

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

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
