Abstract

An oil spill in seawater can pose a significant problem for the process of converting seawater into clean or drinking water. The separation of oil and fats must be carried out as an initial stage (pre-treatment) in the clean or drinking water treatment process. The Dissolved Air Flotation (DAF) system is an appropriate technology for removing oil and fats from raw water, utilizing aeration to create air bubbles in the water that lift the oil and fats to the surface for separation. Seawater characterization includes physical, chemical, and microbiological properties. The research variables in this study include initial oil concentrations (25 mg/L, 50 mg/L, and 100 mg/L), air supply pore sizes (0.5 mm, 1 mm, and 1.5 mm), air supply pressures (0.005 MPa, 0.01 MPa, and 0.015 MPa), and aeration times (30 minutes, 60 minutes, 90 minutes) in the DAF reactor to determine the effect of these variables on oil removal efficiency. Increasing the initial oil concentration leads to a higher pollutant load in the DAF flotation system, resulting in a decrease in the efficiency of the DAF process. On the other hand, smaller air supply pore diameters play a crucial role in increasing oil removal efficiency, as the reduction in pore size significantly impacts the formation of microbubble sizes, thereby providing a larger surface area to lift oil particles from the feed solution.

Abstract

Comfort conditions based on climatology parameters can be considered the comfort level of population in an area. Development in Surabaya area over the past few years has inevitably led to a shift in the function of green land into new buildings, especially residential and industrial ones. This indicated an effect on the condition of thermal comfort due to an increase in surface temperature. Therefore, calculations are carried out to determine the thermal comfort index in Surabaya and spatial analysis to see its distribution. Remote sensing using Landsat imagery is carried out to determine the classification and distribution of vegetation, buildings and water bodies. With overall accuracy about 93%, this land cover of Landsat data is considered good enough to represent the current state of land cover in Surabaya. The results show that there has been a significant change in land cover in almost a decade (2013-2021). The comfort level is best seen at the beginning of the research year (2013) and the lowest one is seen in 2016. Based on these two data, it can be seen that there is a link between the decrease in the quality of the thermal comfort level and the availability of green open spaces. Several things affect the thermal comfort conditions in Surabaya, i.e. geographical conditions, global climate anomaly conditions and the availability of vegetation stands or green open spaces.

Abstract

Taman Hutan Raya (Tahura) merupakan kawasan konservasi penting dalam mendukung pelestarian lingkungan dan keanekaragaman hayati. Fungsi ekologi Tahura juga mencakup perannya dalam menyerap polusi udara melalui vegetasi penyerap polutan. Studi ini bertujuan untuk membandingkan komposisi vegetasi penyerap polusi yang terdapat di Tahura R. Soerjo, Jawa Timur, dengan beberapa Tahura lainnya di Indonesia, seperti Tahura Ir. H. Djuanda (Jawa Barat), Tahura Ngurah Rai (Bali), dan Tahura Bukit Barisan (Sumatera Utara). Kajian ini dilakukan melalui metode tinjauan literatur dari berbagai penelitian terdahulu. Hasil kajian menunjukkan bahwa meskipun terdapat spesies umum seperti pinus (Pinus merkusii) dan mahoni (Swietenia macrophylla), Tahura R. Soerjo memiliki keunikan dengan dominasi vegetasi montana dan sub-montana yang memiliki potensi tinggi sebagai penyerap polutan. Studi ini memberikan wawasan mengenai pentingnya optimalisasi pemilihan jenis tanaman dalam mendukung fungsi ekosistem Tahura sebagai paru-paru kota dan penyerap polusi udara.

Abstract

Forest Parks (Tahura) are vital conservation areas for the preservation of biodiversity and ecological functions in Indonesia. However, various human activities have caused significant damage to these areas. This study aims to assess the level of damage in several Tahura in Indonesia and evaluate the environmental pollution control strategies that have been implemented. The methods used include literature studies and secondary data analysis from various reliable sources. The results of the study indicate that damage in Tahura is caused by factors such as deforestation, illegal logging, and environmental pollution. Effective control strategies involve community participation, law enforcement, and ecosystem rehabilitation. An integrated approach is needed to ensure the sustainability of Tahura in Indonesia.

Abstract

Glucitol is the result of glucose reduction by changing the aldehyde group to a hydroxyl group, hence the name sugar alcohol. Sugar substitute sweeteners have various requirements, namely having a sweet taste, not causing toxicity to the body, calorie, and can be produced in large capacities. The most relevant sugar substitute with these criteria is glucitol. Glucitol factory is planned to be established in Jombang Regency, East Java with a production capacity of 20,000 tons/year. The raw material used in this glucitol factory is using tapioca starch raw material with a catalytic hydrogenation process. In the manufacture of glucitol there are 2 important processes, namely, the first process converts strach into glucose or dextrose with supporting raw materials for amylase enzymes and glucoamylase enzymes in the main tool, namely the reactor. In the catalytic hydrogenation process glucose or dextrose is reacted with hydrogen gas at high temperature and pressure with the help of the addition of nickel raney catalyst. The resulting glucitol is then purified in the evaporator to produce 70% glucitol. In the design of the Glucitol factory requires a total capital investment of Rp. 197,294,444,028 The total production cost of this factory is Rp. 552,393,444,402 with annual sales of Rp. 800,000,000,000. From the economic analysis, BEP was obtained at 23.7% with POT for 2.122 years and IRR of 64.14%. In terms of engineering and economics, this plant is feasible to establish
