The purpose of this study is to plan the parking space for two and four-wheeled cars in the Kayutangan Heritage Area of Malang. Two different types of data are required for this research, namely: Information Sources: Talks, Notes, and Eyewitness Accounts. The list of potential parking spaces from the Ministry of Transportation is secondary information. The largest car parking peak occurred on Saturday, August 12, 2023 based on data collected from Thursday, August 10 to Wednesday, August 16, 2023. Based on the calculation of parking space requirements for two- and four-wheeled vehicles. There are more cars coming. There are plenty of parking spaces, and there is an area of 288 m² (18 mx 16 m) designated for two-wheelers. This gives us 192 parking spaces, but not enough two-wheelers to handle the approaching cars; according to research, 296 spaces are needed. For the incoming cars, a parking lot will be built on the second floor. So, we have 384 spaces, or 288 m2 x 2 = 576 m², which is enough to fit one car. There are 64 four-wheeler parking spaces, each measuring 46 by 21 meters or 966 square meters. The result shows that 63 parking spaces are needed to accommodate the incoming cars.

Currently, paper demand in the world has reached 394 million tons/year, while in Indonesia paper consumption has reached ± 8.9 million tons/year. As demand for pulp increases, paper production in Indonesia also needs to be increased. Paper products are produced from fibrous raw materials such as wood. The reduced availability of wood means that demand for wood raw materials cannot be met. This encourages the pulp and paper industry to look for sources of fiber. One natural resource that is easy to manage as a substitute raw material for the pulp and paper industry is water hyacinth. In this research, the delignification process of paper from water hyacinth was carried out using sodium hydroxide to determine the effect of NaOH on the manufacture of packaging paper with fixed variables, namely cooking temperature 100C, water hyacinth 60 gr, chlorine and starch 2gr each, and the variable changing the concentration of NaOH 2%, 2,5%, 3% with a cooking time of 90 minutes, 100 minutes and 110 minutes to obtain a paper tensile strength of 4,683 kN/m2, paper weight (gramatur) of 70 gr/m2 with a paper thickness of 0,7 mm.

Using bioplastics as a substitute for plastics that decompose more slowly is one way to overcome the problem of plastic waste. Natural polymers are the basic ingredients of biodegradable plastics, or bioplastics. Water and microorganisms are two tools that can be used by the environment to break down bioplastics. The main qualitative research methods in this research are observation of test phenomena, biodegradation assessment, and water absorption capacity assessment. Biodegradation tests measure the rate at which microorganisms or the environment degrades biodegradable polymers. To find out how effectively plastic decomposes, samples of biodegradable plastic are planted in the soil. Based on samples with glycerol sorbitol content of 15%, 20% and 25%. The 15% concentration group experienced damage or weight loss more quickly compared to samples containing 20%, 25% and 15% glycerol. One thing that is taken into account in evaluating the quality of bioplastics is their ability to absorb water. Because it is related to how long plastic can last in storage, the greater the water absorption capacity of a bioplastic, the worse its quality. From the analysis of biodegradation and water absorption tests, the lower the concentration of glycerol and sorbitol, the more fragile the plastic produced, less elastic, and more easily decomposed by water, soil and other microorganisms. The higher the concentration of glycerol and sorbitol, the higher the results obtained. The plastic produced will be harder so that it is not easily decomposed or damaged.
