Abstract

Road quality is also affected by temperature and weather, leading to surface pavement deformation. It is necessary to improve the quality of the road pavement so that the quality of the road becomes more durable and stable. Hot Rolled Sheet – Wearing Course (HRS-WC) is flexible and has high durability. The natural mineral has been used as the filler for pavement construction. However, further research is necessary to obtain alternative and more sustainable materials. This study will discuss portland cement filler as a reference to compare filler replacement with chitosan powder (shellfish) based on the general specifications of the 2018 highway revision 3 division 6. Chitosan powder contains calcium oxide of 3.04%  and silica oxide of 17.98%, which are similar to cement fillers. The composition of chitosan powder are 100%: 0%, 50%: 50%, 25%: 75%, and 0%: 100%. performance analysis is done through the marshall test. The results showed that the comparison of the use of the best chitosan powder was at the asphalt content of 7.3 with 50% : 50% with a marshall test value of 993.4 kg, flow 3.20 %, VMA 18.36%, VFB 72.01%, VIM 5.14, MQ 301.440 kg/mm. From the result which meets the requirement, the filler has shown quality improvement as an additional mixture according to (SNI 03-6723-2002). Hence still not optimal to replace portland cement because, from the value of the marshall test, portland cement has a higher marshall value than chitosan.

Abstract

Sisa hasil buah bisa menjadi produksi pupuk organik golongan cair serta menambahkan EM4 yang berfungsi mempercepat proses fermentasi atau sebagai activator karena memiliki kandungan mikroorganisme yang dapat memecah senyawa polimer menjadi monomernya. Dalam penelitian ini menggunakan percobaan eksperimental menggunakan metode fermentasi. Bahan yang digunakan yaitu sisa buah yang tidak dikonsumsi, EM4 (Effective Microorganisme), gula merah dan air. Ada beberapa variabel yang ditentukan dalam percobaan ini, yaitu variabel tetap, variabel terikat, dan variabel bebas. Variabel tetap yang ditentukan dalam percobaan ini merupakan jumlah limbah buah-buahan yang digunakan yaitu sebanyak 6000 gr; volume air gula merah sejumlah 1800 ml; dan volume EM4 yaitu 180 ml. Selain itu, terdapat variabel terikat; yakni uji pH; uji suhu; uji warna; dan juga uji bau. Sedangkan variabel bebas yang digunakan adalah waktu fermentasi yaitu 7 hari. Hasil dari penelitian hari ke-7 nilai pH sebesar 3,7, nilai suhu dari 24 meningkat menadi 32,6, warna pupuk cair dihari pertama cenderung coklat yang berasal dari gula merah dan EM4 kemudian secara perlahan warna dari pupuk berubah menjadi warna kuning, sedangkan bau tidak terlalu menyengat dan lebih menyerupai tape. Dari air gula sebanyak 1800 ml dan 180 ml EM4 menggunakan limbah buah-buahan menghasilkan pupuk organik cair sebanyak 800 ml.

Abstract

Infrastructure development has occurred very rapidly in Surabaya in the last few decades. There is pressure on the need for land use in line with the increase in population. This study aims to analyze changes in land cover with inter-decade analysis and predict land cover in 2021-2030 in Surabaya using the Multi-Layer Perceptron method. The data used in this research is Landsat satellite which is considered good in representing the actual land cover. A decrease in the amount of vegetation occurs every decade in Surabaya, while the number of buildings is increasing and the bodies of water are relatively the same. The Multi-Layer Perceptron method has a good level of accuracy in predicting land cover in the city of Surabaya. In 2021-2030 it is predicted that Surabaya will still experience an increase in the number of buildings and a decrease in the amount of vegetation.

Abstract

Water is essential for all living things, including humans. Water, both in terms of quality and quantity, will have an effect on human life. The Indonesian government is preparing the National Urban Drinking Water Supply Plan (NUWSP) with assistance from the World Bank. A significant portion of the Bank's financial resources are allocated to technical assistance and capacity building in support of the Indonesian government's infrastructure expenditures in all urban water distribution platforms. The NUWSP Work was implemented during an 11-month period, from November 18, 2021 to August 22, 2022, with the NUWSP Work Location at Gresik Regency in East Java. During the data collection stages, both primary and secondary data were obtained. The drinking water supply system (SPAM) planning stage comprises calculating BOQ and RAB, as well as DED for drinking water, and planning for the drinking water JDU system. The contractor takes measurements and standards before installing a field-specific bow plank at the tying point. To avoid pipe damage, individual pipe fittings must be lowered into the trench using the right equipment. The volume of excavation is computed using a depth of 180 cm, a breadth of 60 cm, and a length of excavation of 31 km from six pieces of a pipeline. The Bill of Quantity (BOQ) and Budget Plan (RAB) necessary to complete the SPAM pipeline network work in Gresik Regency were IDR 27,823,590,000.00, based on the results and discussion of the Optimization of SPAM Network Work (NUWSP) in Gresik Regency.

Abstract

This study aims to determine how much dust, SO2 and NO2 concentrations are in the air and to know the description of the distribution of air in the study site. In addition, this research also aims to design air pollution control devices that can be used to control the emissions produced. The method in this research uses the Gausse method in modeling and uses AERMOD software and Google Earth to complete the model description. It is known that the farthest distance the highest concentration of dust spread is 0.071 km with a dust concentration of 101.3 µg/m3. The farthest distance the highest concentration of SO2 spread was at a distance of 0.051 km with a value of SO2 concentration of 6753.3 µg/m3. The farthest distance the highest concentration of NO2 spread was at a distance of 0.051 km with a value of NO2 concentration of 91.45 µg/m3. The air controller uses a bag filter with 6 compartments for dust control and uses silica absorbent and activated charcoal for controlling NO2 and the Flue-Gas Desulfurization (FGD) method for SO2.

Abstract

The final disposal of waste generation is a major environmental challenge in urban areas, especially in developing countries. Waste generation in developing countries will continue to grow as seen from the economic growth and changes in the consumptive patterns of the people, where current lifestyles and activities produce quantity of waste quickly. Waste is not only produced from households, but also from public facilities, such as school, institution, health, offices, markets, hotels, restaurants, and industries which later contribute to the generation of waste in the landfill. Waste management activities in landfills can produce various kinds of greenhouse gas emissions. This study aimed to determine the potential for greenhouse gas emissions from the rate of waste generation in Randegan TPA, Mojokerto City according to the parameters of the waste composition. Based on the research results, it was known that emissions generated from household waste amounted to 1.35 Gg CH4 and 3.72 Gg CO2, while non-domestic waste is 0.264 Gg CH4 and 0.728 Gg CO2.

Abstract

Jeans dyeing is one of the large or small scale industries that produces liquid waste from the coloring process. Liquid waste that enters the water will cause environmental pollution. It is necessary to study about the nature and characteristics of jeans dye wastewater through the toxicity test that refers to USEPA (2000) and OECD (2004) standards. Tests carried out by entering the concentration of certain wastewater in 5 (five) reactors with tilapia fish (Oreochromis niloticus) biota. Preliminary research conducted in 7 day acclimation process and 1 day range finding test. Running process carried out for 96 hours for fish 5 cm. The analysis was carried out every 24th, 48th, 72th and 96th hour for analysis of temperature, pH, DO, and mortality. Heavy metal (Cr) analysis was carried out in fish bodies and wastewater at each concentration. The initial characteristics of jeans stained liquid waste for pH: 7, temperature: 30, 7ºC, DO: 8.5 mg/l, TSS: 1040.0 mg/l; BOD: 137 mg/l; COD: 484.8 mg/l and Total chrome: 3.079 mg/l. The level of LC50 toxicity concentration in tilapia fish fish 5 cm size of 12.59% results obtained from the calculation of probit with excel software. The content of chrome total (Cr) contained in the test biota for 96 hours ranged from 1.03 l/kg to 1.93 l/kg.
