Pembentukan Komposit Zeolit X - Bayerit dari Perlakuan Abu Sekam Padi dan Aluminium Kemasan Produk Pangan dalam Larutan NaOH Teknis pada Suhu Ruangan

2023-07-06T15:04:00+07:00

Various research efforts have been carried out to obtain efficient zeolite synthesis methods, including the use of waste as the main ingredient or carried out at room temperature. One type of zeolite that has been synthesized at room temperature is zeolite X (ZX) within a minimum of 28 days using synthetic chemicals. The purpose of this study is to explore how ZX can be formed from waste materials and NaOH technical grade solution (TGS) at room temperature for 40 days without stirring treatments. The waste materials are rice husk ash from the traditional red brick industry, aluminum beverage cans, and food packaging aluminum waste. The materials were homogeneously mixed with the NaOH TGS in such a way as to produce a mixture with a mole ratio of 7.23Na2O : 0.26Al2O3 : 1SiO2 : 280H2O, with mole ratios of Na2O/H2O and Al2O3/SiO2 that were 30% higher than the literature for ZX synthesis, respectively. The results of characterization showed that the treatment yield was ZX along with the presence of the bayerite phase, which had been formed since the 20-day observation period. The use of excess Na2O/H2O and Al2O3/SiO2 mole ratios in this study impacts the formation of bayerite first and the ability of dissolved silica to condense, thus slowing the crystallization of ZX. The result of this study led to the new finding that zeolite-bayerite composite can be synthesized directly in a simple, inexpensive, and environmentally friendly manner, where the composite materials have been reported as catalysts and adsorbents.

Acid mine drainage is mining waste that contains a lot of sulfate and heavy metals such as Fe and Mn which can cause environmental damage and pollute the ecosystem, therefore it needs to be managed. One way to manage acid mine drainage is with phytoremediation techniques using Purun tikus (Eleocharis dulcis). The ability of Purun tikus to accumulate heavy metals can be known by calculating the bio-concentration factor (BCF) and tranclocation factor (TF). This study aims to determine the value of bio concentration factor (BCF) and tranclocation factor (TF) in rat purun in absorbing Fe and Mn so that it can be used for coal mine acid water management. Sampling was conducted using Convenience sampling method. Analysis of Fe, Mn, BCF and TF levels was carried out using an atomic absorption spectrophotometer. In the study, the bio concentration factor (BCF) value for Fe was 7.53, and for Mn was 30.09. While the value of the tranclocation factor (TF) for Fe is 0.77 or the value of TF less than 1, this indicates that rat Purun in accumulating Fe metal uses a phytostabilization mechanism. Then the tranclocation factor (TF) value for Mn is 1.44 or TF value more than 1, indicating that in accumulating Mn metal, Purun rats use a phytoextraction mechanism.

The zooplankton ecological index which includes diversity, uniformity and dominance is one approach used to determine the condition of the aquatic environment. This study aims to determine the environmental status of the waters based on zooplankton ecological index which includes diversity, uniformity, and dominance in Doreri Bay water, Manokwari. This study was conducted in September 2020 at two 5- and 10-meter stations depth from the water's surface. Water quality measurements and water sampling were carried out at both stations thrice for 1 week. Water sampling to determine individual zooplankton used a 5 L volume Van Dorn. Temperature, salinity, and pH of the waters were measured successively using a rod-type thermometer with a 50 °C scale, a handheld refractometer RHSN-10ATC, and a pH meter of Orion A215 type. The measurement results obtained the temperature, salinity, and pH values ranging from 29.1 – 29.9 °C with an average of 29.5 °C, 30 – 35 ppt with an average of 33.2 ppt, and 7.9 – 8.3 with an average of 8.1, respectively. The diversity, uniformity, and dominance indexes ranged from 1.5 – 2.2, 0.7 – 1.0, and 0.1 – 0.4, respectively. The ecological status of Doreri Bay waters based on the diversity, uniformity, and dominance indexes show that the components of the food chain are still complete, including the producer and consumer groups and reducers. The effect of liquid waste from land activities around the bay has not disturbed the zooplankton.

2023-07-06T15:07:18+07:00

Fish waste generated from industrial activities in coastal communities has the potential to cause bad odors and pollute the environment. Falling mangrove leaves also contribute to waste in coastal areas because there are mangrove forests. This can pollute the environment so that fish waste and mangrove leaves can be processed through the composting method. Composting with BSF larvae can provide double benefits, namely reducing waste and producing larval feces that plants need. Papaya fruit waste that is no longer suitable for consumption can be used as a biostarter to speed up the decomposition process. The research variable was the use of 200 ml/kg papaya fruit biostarter. Variation in composition 100% mangrove leaves, 50% mangrove leaves; 50% fish waste, 70% mangrove leaves; 30% fish waste. Moisture content, temperature, pH, C/N, phosphorus, and potassium in several variations of this study met the quality of compost based on SNI 19-7030-2004. Based on MANOVA statistical analysis, variations in composition and type of biostarter influence larval biomass, feed consumption, and waste reduction index. Based on the quality of the compost, the best variation in this study was the composition of 50% fish waste compost and 50% mangrove leaves without the use of a biostarter.
