Abstract

Air pollution, especially in big cities in Indonesia, has reached a very worrying level. The main sources of air pollution come from various human activities, including industry, transportation, offices, and housing. These various activities are the biggest contribution of air pollutants that are released into the free air. In this study, observations and measurements of air pollution levels were carried out in the Final Disposal Site (FDS). The absence of good waste management in Sinjai Regency has triggered the community to manage waste by means of Open Dumping, where waste is simply dumped in a landfill without any treatment. Pollutant gas originating from the landfill will produce harmful gases, including Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2) and others. This study aims to determine the concentrations of Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) in Final Disposal Site (FDS) Tondong and in residential areas around Tondong FDS, Sinjai Regency by using the passive sampler method. The test results obtained are the NO2 value at point 1 which is 3.69 g/m3, point 2 is 5.25 g/m3, point 3 is 3.1 g/m3 and point 4 is 7.1 g/m3 with an average value The average NO2 parameter test is 4.785 g/m3. While the SO2 value at point 1 is 4.46 g/m3, point 2 is 7.34 g/m3, point 3 is 8.47 g/m3 and point 4 is 5.93 g/m3. The average value of the SO2 parameter test is 6.55 g/m3. Calculating the Air Quality Index based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 27 of 2021 concerning the Environmental Quality Index, air pollution at the Tondong Landfill is worth 93.14 indicating the very good category.

Abstract

National salt production capacity is dominated by smallholder salt production through the crystallization process in traditional salt ponds. One of the salt producing areas in South Sulawesi Province is located in Jeneponto Regency. Salt farmers in Jeneponto Regency produce salt through traditional salt ponds. Jeneponto Regency is also one of the main coconut producing areas. Coconut coir from the people's plantation industry is currently only used as fuel in small and medium home industries or is simply thrown away as waste. Coconut coir has the ability to absorb water. The aim of this research is to innovate the use of coconut coir waste to increase the surface area for water evaporation in traditional laboratory-scale salt ponds. This research was also carried out by conducting analysis on traditional ponds to study the factors that influence the salting process. Next, the salting process was carried out on a laboratory scale by making a replica of the traditional pond salting process which was equipped with the addition of coconut coir to increase the evaporation surface area. The results of the research show that the salting process in traditional salt ponds is greatly influenced by the season. The sun plays a very important role in the evaporation process in traditional salt ponds until salt crystals form in the ponds. Laboratory scale salt pond equipment shows that the use of coconut coir plays a very important role in speeding up the evaporation process and has the potential to increase salt production in traditional salt ponds.

Abstract

One of the important processes in the clean water treatment process is coagulation. Parameters that influence the coagulation process are pH and coagulant concentration. Tapioca flour can be used as a natural coagulant to reduce turbidity. In this research, river water was used as a source of raw water used in the clean water processing process which has a turbidity of 13.36 NTU. The jar test was carried out to determine the effect of coagulant concentration and pH on reducing turbidity. The coagulation process was carried out using variations in coagulant concentration (1,2,3,4,5 and 6 ppm) and 4 variations in pH (3,5,7 and 9). The results showed that the amount of turbidity reduction varied at each pH used. The coagulation process which takes place in very acidic conditions (pH = 3) results in a greater reduction in water turbidity, namely 3.20 NTU. Almost the same level of turbidity reduction was also seen in the coagulation process which took place at pH 5 and 7, namely 5.22 NTU and 4.30 NTU. Meanwhile, coagulation under alkaline conditions (pH = 9) will result in a smaller decrease in turbidity, namely 11.43 NTU. Based on the final turbidity measurement results, it can be seen that the amount of turbidity reduction is also greatly influenced by the coagulant concentration. Changes in turbidity reduction with variations in coagulant concentration vary at each pH used. At pH 3,5,7 and 9 the decrease in turbidity will be greater at a concentration of 6 ppm. The reduction in turbidity proves the effectiveness of the effect of increasing coagulant concentration and pH using tapioca flour as a natural coagulant in the clean water treatment process.

Abstract

Bioplastik merupakan plastik yang terbuat dari bahan alam dan dapat terdegradasi oleh alam. Penelitian ini bertujuan untuk mengetahui pengaruh rasio antara pati biji asam dan serat ampas teh, dengan penambahan kitosan terhadap sifat mekanis bioplastik. Bahan utama yang digunakan adalah pati biji asam, ampas teh, kitosan, dan sorbitol. Variabel yang diuji meliputi perbandingan berat pati:ampas teh (5:5 g, 6:4 g, 7:3 g, 8:2 g, 9:1 g) dan variasi konsentrasi larutan kitosan (10%, 20%, 30%, 40%, dan 50%). Proses pembuatan bioplastik melibatkan pemanasan pada suhu 80°C selama 25 menit dan pengovenan pada suhu 60°C selama 4 jam. Hasil penelitian menunjukkan bahwa rasio pati dan serat yang paling optimal terhadap kuat tarik terjadi pada konsentrasi kitosan 40% pada perbandingan 7:3 (g) dengan nilai 28,42 MPa. Sedangkan nilai persen pemanjangan terbaik ditemukan pada bioplastik dengan konsentrasi kitosan 10% pada perbandingan 8:2 (g), sebesar 27,5%. Bioplastik berbahan dasar pati biji asam menunjukkan potensi besar untuk menggantikan plastik konvensional. Dengan menggunakan bahan-bahan alami yang dapat terurai oleh alam, seperti pati dan kitosan, bioplastik ini menawarkan solusi yang lebih ramah lingkungan, mengurangi dampak limbah plastik, dan dapat digunakan dalam berbagai aplikasi, seperti kemasan dan produk sekali pakai.

Abstract

Tofu also has a weakness, namely its high water content, so it is easily damaged because it is easily overgrown by microbes. Preservatives added are not limited to preservatives that are allowed, but many businessmen are naughty by adding formalin. White tofu is one that is circulating in the market. At room temperature the yower storage knows an average of 1-2 days. Efforts to preserve tofu by means of steaming and storing in a refrigerator can only preserve tofu for 1 day. This causes traders to commit fraud, one of which is preserving tofu so that it is durable, one of which is the addition of chemicals. According to the Food and Drug Supervisory Agency (BPOM). The treatment research method with the application of chitosan as an edible coating on white tofu is carried out in four stages, namely the preparation stage, immersion stage, storage stage, and testing stage. The preparation stage is carried nut by preparing all the materials and tools that will be used in the immersion, storage and testing stages. The immersion stage was done by soaking white tofu with concentrations varying of 0.5%  The results of the long storage test for tofu coated with chitosan showed that the tofu soaked with chitosan solution with the addition 0.01 %.
