IOP Conference Series: Earth and Environmental science 2021年第1期894卷

作者： D A Widyaningrum A Rinanti R Hadisoebroto Environmental Engineering Study Program Faculty of Landscape Architecture and Environmental Technology Universitas Trisakti Jakarta Indonesia

Industrial waste that contains high concentration of iron heavy metal (Fe2+) needs to be reduced into a safer limit for water ecosystem using an environmental-friendly, sustainable and low cost technology. This literature study was aimed to gather information on Fe2+ metal ion removal with biosorption method by mobilized beads-shaped Desmodesmus sp. green microalgae. Biosorbent beads are made of Desmodesmus sp. green microalgae powder binded with Na-alginate polymer. Desmodesmus sp. microalgae were cultivated in an Erlenmeyer flask with wastewater contains Fe2+ and Beijerinck growth media controlled in batch system. Analysis was conducted to study the influence of pH, size, beads, beads concentration, and Na-alginate concentration towards Fe2+ heavy metal removal efficiency on biosorption process. Research results revealed that Fe2+ heavy metal was effectively adsorbed by 1 mm beads up until 46% at maximum capacity on pH level of 6. These beads contain 8% gr/L of microalgae powder and 9% gr/L of Na-alginate. The involved function groups in Fe2+ sorption and the beads biosorbent morphology changes were analyzed by using FTIR and SEM. This biosorption research was following by analysis of Freundlich isotherm and reaction kinetics order two with linear approach. This was to shows the beads possess adsorption kinetics with optimum Fe2+ absorption capacity. Desmodesmus sp. beads are highly potential to be used as biosorbent since the heavy metal removal process was selectively conducted on wide pH level and temperature ranges, fast adsorption kinetics, and low operational cost. The smaller the beads size the wider the surface area, which leads to higher removal efficiency rate.

Kenteng Village has the potential for beef development due to its high cattle population. However, cow dung waste produced by farmers has not been optimally used, hence its additional benefits have not contributed to the community's economy. This has also led to environmental pollution due to improper waste management. Therefore, empowerment efforts are needed to improve farmers' knowledge and skills in managing livestock manure to increase their income and create environmentally friendly conditions through training activities on the manufacture of organic bio-slurry fertilizer as well as maintenance and construction of biogas installations using fixed dome plant technology. Furthermore, the training was held from August 15-September 26, 2021, in Kenteng Village, Nogosari District, Boyolali Regency. The empowerment program is implemented through Focus Group Discussion (FGD), extension, training, demonstration plots on the production technology of organic fertilizer and biogas for fuel production. Materials used in producing the fertilizer include slurry obtained from biogas waste and agricultural lime/dolomite. The dome plant constructed contains a digester with 6 main parts, namely inlet, reactor, gas reservoir, outlet, gas transport system and compost pits for degassed animal manure/bio-slurry. The training result shows an increase in farmers' knowledge and skills on the application of bio-slurry organic fertilizer production technology and the construction of biogas installations as a fuel producer. There was also an increase in their income, which improved their standard of living. Conclusively, the community in Kenteng Village was more empowered by the existence of a biogas installation development program.

The increasing demand for sustainable materials has highlighted nanocellulose as a promising candidate due to its exceptional mechanical strength, thermal stability, and superior barrier properties. These attributes enable its application in diverse fields, including packaging, biomedical devices, and nanocomposites. This study investigates the valorization of edamame bean husks, a byproduct of the globally consumed legume snack, as a sustainable feedstock for nanocellulose production. Cellulose was extracted from the husks via delignification and bleaching, followed by a green and facile acid hydrolysis method employing organic acids (maleic acid, lactic acid, citric acid, and formic acid) to produce nanocellulose. The resulting nanocellulose exhibited a fibrillar morphology with particle sizes ranging from 7.59 to 17.51 nm, depending on the acid used. X-ray diffraction analysis revealed a crystallinity index ranging from 63.49 % to 67.24 %. Notably, acid hydrolysis significantly enhanced the thermal stability of the nanocellulose compared to both the raw husk and isolated cellulose. These findings demonstrate the potential of edamame agricultural waste as a valuable resource for sustainable and eco-friendly nanocellulose production, contributing to a circular bioeconomy. © 2025 The Authors

Scientific World Journal 2022年第1期2022卷 3123788页

作者： Gandharum, Laju Hartono, Djoko Mulyo Karsidi, Asep Ahmad, Mubariq School of Environmental Science Universitas Indonesia (UI) Jl. Salemba Raya No. 4 Jakarta 10430 Indonesia Center of Regional Resources Development Technology (PTPSW) National Research and Innovation Agency (BRIN) Gedung Geostech 820 Banten 15314 Indonesia Environmental Engineering Study Program Faculty of Engineering Universitas Indonesia (UI) Depok 16424 Indonesia Department of Geography Faculty Mathematics and Natural Sciences Universitas Indonesia (UI) Depok 16424 Indonesia

Uncontrolled urban expansion resulting from urbanization has a disastrous impact on agricultural land. This situation is being experienced by the densely populated and fertile island Java in Indonesia. Remote sensing technologies have developed rapidly in recent years, including the creation of Google Earth Engine (GEE). Intensity analysis (IA) is increasingly being used to systematically and substantially analyze land-use/land-cover (LULC) change. As yet, however, no study of land conversion from agriculture to urban areas in Indonesia has adopted GEE and IA approaches simultaneously. Therefore, this study aims to monitor urban penetration to agricultural land in the north coastal region of West Java Province by applying both methods to two time intervals: 2003-2013 and 2013-2020. Landsat data and a robust random forest (RF) classifier available in GEE were chosen for producing LULC maps. Monitoring LULC change using GEE and IA has demonstrated reliable findings. The overall accuracy of Landsat image classification results for 2003, 2013, and 2020 were 88%, 87%, and 88%, respectively. IA outputs at interval levels for all categories showed that the annual change-of-area rate was higher during 2013-2020 than during 2003-2013. At the category level, IA results showed that the area of agricultural land experienced net losses in both periods, with net loss in 2013-2020 being 2.3 times greater than that in 2003-2013 (∼1,850 ha per year). In contrast, the built-up area made net gains in both periods, reaching almost twice as much in the second period as in the first (∼2,030 ha per year). The transition-level IA performed proved that agricultural land had been the primary target for the expansion of built-up areas. The most extensive spatial distribution of land conversion from agriculture to built-up area was concentrated in the regencies of Bekasi, Karawang, and Cirebon. These findings are intended to provide stakeholders with enrichment in terms of available literature

Along with the increasing of infrastructure development in Indonesia especially in jepara, so the necessary of material also increase, for example: sand. Nowadays, muntilan is the sand that often be used in making infrastructure in the government because it is considered that it has the good quality, whereas in the other hand the river sand is also abundant, but the government perverted mintilan sand as the development material. River sand is usually used by the middle to lower county because the house because the price is cheaper than muntilan sand. After doing this research we hope that: can know the quality of the river sand if it is used in infeastructure, knowing the river sand in jepara that have the good quality, such as: keling sand, bangsri sand, The stages of this research are: preparation, sand inspection (mud content and organic faces, filter analysis, moister content and weight, and specific gravity), making spacimens based on SKSNI 03-6825-2002 ASTM C 305, making compressive strength test. The test result show that at 3,7,14,21,28 days old show that keling sand (93,2 kg/cm2), bangsri sand (135,2 kg/cm2). The use of river sand as the construction material by the government and community will have consequence on the balance kf muntilan sand and river sand. The specific treatment on the river sand will that quality that is almost same as muntilan sand. © Published under licence by IOP Publishing Ltd.
