SELULOSA NANOSERAT TANDAN SAWIT SEBAGAI MATRIKS FILM INDIKATOR ALAMI KESEGARAN PANGAN
Get PDFThe food freshness is one trending topic that currently studied to reduce the number of food waste. The development of food freshness film indicator is one technique that can be utilized to resolve the high number of food waste. The objective of this study was to evaluate the ability of cellulose nanofiber film that had been integrated with anthocyanine as the food freshness film indicator. Cellulose nanofiber was obtained from empty fruit bunch of palm oil that had been dried, cut, and milled into fine powder. The initial step of this preparation was bleaching process using NaOCl/NH3 and H2O2/NH3. After bleaching process, cellulose fiber was oxidized using TEMPO/NaOCl/NaBr at pH 10 for 6 h. The TEMPO-oxidized cellulose fiber was then transferred into high pressure-homogenizer for 6-cycles at 800 bar of pressure. The cellulose nanofiber was obtained as hydrated fiber (gel-like) and then combined with anthocyanine obtaining from red cabbage extract, the film was casted on the acrylic plate. The film indicator of cellulose nanofiber was analyzed to determine the characteristic of film, i.e., color stability depending on pH, morphology, mechanical properties, and color response of film on the food freshness. The film of cellulose nanofiber that integrated with anthocyanin extract has the good sensitiveness to test the food freshness at 4oC. The color change produced by this indicator film is quite significant and has a different color at each pH value
Estimation of methane emission from Piyungan landfill using IPCC method
Get PDFOne of the greenhouse gases that causes climate change is the emission of methane (CH4) produced by landfills. The methane comes from the anaerobic decomposition of organic matter in the waste at the landfill. The purpose of this study is to estimate methane emissions at the Piyungan landfill, Bantul, Yogyakarta, from 2021 to 2025 using IPCC method. No similar work has been conducted so far, especially in the Piyungan landfill. The result shows that methane emissions produced at the Piyungan landfill in 2021 is 544.05 tons with a total waste generation of 549.49 tons/year and is dominated by 88% organic waste. Meanwhile from 20,786 tons of waste generated in 2025, the methane emissions are estimated to be 573.85 tons. To minimize the methane emission from Piyungan landfill, it is recommended mitigation and adaptation efforts, i.e., the 3R method (reduce, reuse, recycle), the composting of organic waste, the addition of gas ventilation pipes. The methane gas from the Piyungan landfill should be explored as alternative energy fuel in future work

Optimization of The Proportion of Salted Egg in the Crackers Making Process in terms of Crispness, Nutritional Value, and Hedonic
Get PDFCrackers are one of the foods that are in demand by all circles of society. Salted egg crackers are an innovative product of egg crackers made from duck eggs. Salted egg crackers are made from duck eggs that are processed into salted eggs then mixed with tapioca starch and added with other spices to improve the flavor and nutritional content. This study aims to determine the effect of different proportions of salted eggs on the nutritional content, physical quality, and consumer liking of salted egg crackers. There are 5 treatments of different proportions of eggs, namely 0 g (To ), 62.5 g (T1), 125 g (T2), 187.5 g (T3), and 250 g (T4). The research method consists of experimental design, research procedures, parameter analysis and data analysis. The results of the analysis showed that the difference in the proportion of salted egg addition to salted egg crackers affects the levels of protein, ash, fat, and calories. The higher proportion of salted egg will make protein and ash levels increase, while fat and calorie levels decrease. Physical and hedonic analysis showed that the highest crispness and most preferred by panellists overall was found in the proportion of salted egg 125 g (T2). In conclusion, optimising the proportion of salted egg at 48% or 125 g of 387 g total dough produces good quality and crispy crackers
Hydrodynamic numerical investigation and sedimentation, a study cases in Lontar steam-electric power plant
Get PDFThe intake pump of the Lontar steam-electric power plant cannot operate optimally due to a drawdown in the forebay. The capacity of the conveying channel decreases, possibly caused by sedimentation at the intake mouth. So, an initial investigation is required using hydro-oceanographic and sedimentation numerical modeling in that area. Numerical modeling is conducted to simulate flow phenomena to obtain a model and measurement data for qualitative assessment. Hence, the flow condition in the study area is a mix of ocean current and circulating water pump discharge. Hydrodynamic modeling has been successfully conducted to assess their interaction in this zone properly by using open-source software called Delft3D Hydro-morphodynamic. This research uses primary data or field measurement data like bathymetry, sediment, and discharge data for input. Model calibration used tidal and current data. Based on the results of the numerical modeling, it is evident that sediment deposition occurs at the intake mouth area due to the suction of the circulating water pump unit, resulting in sediment being carried and deposited during high water levels and a slowing down of flow rate. Sedimentation issues can addressed through dredging, and for the long-term recommendation to install a breakwater to extend the dredging service life at the intake mouth
