Abstract

The availability of hydrological data poses a challenge in water infrastructure development. Common issues in this domain often arise due to the lack of comprehensive data availability. Utilizing high-resolution satellite-based rainfall measurements covering extensive areas presents a potential solution. However, variations in the observed rainfall data resolution may impact the accuracy of the data. This study employs Tropical Rainfall Measurement Mission (TRMM) rainfall data and compares it with rainfall data from observation stations to assess the suitability of TRMM as a hydrological data source. Validation analysis is conducted using the Root Mean Squared Error (RMSE), Nash-Sutcliffe Efficiency (NSE), Correlation Coefficient (R), and relative bias (RB) methods. Validation results indicate that corrected TRMM data yields better outcomes compared to uncorrected TRMM data, with lower RMSE, higher NSE, and increased RB values. The most favorable findings occur at the Batu Busuk station, with RMSE = 22.554, NSE = 0.181, R = 0.95, and RB = 0.413. These findings suggest thatcorrected TRMM data can be effectively used as a hydrological data source in water infrastructure development

Abstract

The need for paper in Indonesia continues to increase along with population growth and progress in activities related to paper use. However, the supply of materials used to make wood pulp will also decrease over time. Continuous exploitation of forests will cause environmental problems. An alternative to reduce the impact on the environment is to replace the raw material for making non-wood paper which is rich in cellulose fiber. One non-wood raw material that is rich in fiber is areca nut shell. However, the current problem is that paper can be contaminated with microorganisms from free (dirty) air, dirty hands of people who handle it or from unsterile storage places. So,we need a new alternative to prevent this problem, namely by adding antibacterial additives to the paper. The method used is the process of delignification, filtration, drying, bleaching and adding chitosan additives. The conclusionsobtained that the optimum concentration of the NaOH cooking solution was found at a NaOH concentration of 10%, the optimum time was obtained at a delignification time of 6 hours, and the best concentration of chitosan additive was 6% with an inhibition zone of 7.01 mm. The inhibition zone obtained is in the weak category.

Abstract

Corn cobs are a waste that is rarely used and their presence continues to increase with increasing corn production capacity. The starch and carbohydrate content in corn has the potential to be used as bioethanol. This also answers the problem regarding the availability of fossil fuels in Indonesia which is starting to run low, so the presence of biomass-based fuel is the right solution. Bioethanol is a biochemical liquid obtained from the fermentation of sugar from carbohydrates with the help of microorganisms. Corn cobs have a high cellulose content so they have great potential as raw material for making bioethanol. Using corn cobs as the main ingredient in making bioethanol can reduce agricultural waste, preserve nature and increase economic value. This research aims to obtain the optimal yeast weight and fermentation time to produce the highest levels of bioethanol. The process of making bioethanol generally goes through three processes, starting from the hydrolysis process with 0.5 N sulfuric acid, the fermentation process with yeast (Saccharomyces cerevisiae), and the distillation process at a temperature of 100 °C. The fermentation process with the addition of yeast was varied by 1 gram and 3 grams with 0.09 grams of urea. Fermentation time was 1 day, 2 days and 3 days. The results of the research obtained the highest ethanol content, namely 11% on day 1 with the addition of 1 gram of yeast

Abstract

Coconut trees are plants that are easily found in tropical areas such as Indonesia; therefore, natural products are abundant, but the use of waste from coconuts has not been processed into technological products. The aim of this study was to determine the differences in the variations in the volume fraction of fibers during tensile and impact strength testing. The variations in the volume fraction used were 5%, 10%, and 15% fiber, and the chemical treatment of the fiber was alkalized using 20% ethanol for 3h of soaking. Composite manufacturing uses a hand layup method with random fiber orientation. The results of the research on variations in volume fraction of 5%, 10% and 15% obtained test values, in tensile testing such as maximum load obtained 32,844 kgf, 106.44 kgf and 105.59 kgf, maximum stress 6.0510 N/mm2, 16,893 N/ mm2 and 17.249 N/mm2, elongation breaking strain 0.8150, 0.3275 and 0.2617, breaking strain 1.4818 %, 0.5955 % and 0.4758 %, for the tensile test value the impact energy value was found tobe 1.6 kgf, 2.3 kgf and 3.3 kgf and impact prices of 1.84 kJ/m2 , 2.45 kJ/m2 and 3.45 kJ/m2 . The high tensile and impact test results were due to mixing coconut fiber which had gone through ethanol alkalizing treatment with coconut charcoal powder to obtain high impact and tensile values

Abstract

The Wrati River is located in PasuruanRegency. This river crosses three sub-districts and six sub-districts, with a total distance of 13.6 kilometers. The subdistrict through which this river passes has land use for household, agricultural, and industrial purposes. These activities hurt rivers, causing pollution and decreasing water quality. Determining water quality status is very important to understand the suitability of river water for various purposes. Understanding water quality can be fundamental information for managing and preventing river pollution. The pollutant index approach used in this research refers to the guidelines in the Decree of the Minister of the Environment Number 115 of 2003. The research results show that the water quality of the Wrati River from upstream to downstream is included in the lightly polluted category at each sampling point, with an index value of 4.94. The main factor causing light pollution in Wrati River water is the excessive phosphate content and other parameters that exceed the specified quality standards. Based on the findings of this research, waste management efforts need to be made to improve the quality of this river water
