Abstract

The research conducted on Jalan Taman Siswa No. 9 aims to determine the coherence between the number of two-wheeled and four-wheeled vehicles and the noise level on the highways around the campus. The data noise collection method uses a Sound Level Meter (SLM) with the HT-80A type and also counts the number of two-wheeled and four-wheeled vehicles passing by using the Traffic Counter application that has been installed in a smartphone. Noise can have an impact on human health, especially hearing problems and also cause inconvenience to both road users and residents in the vicinity. The variables that will be discussed are: volume of vehicles, especially two-wheeled and four-wheeled vehicles, and noise intensity. This data collection is needed to find the noise level and then compared using the standard allowable level, namely using the Decree of the State. Minister for the Environment No: Kepmen-48/MENLH/11/1996 for residential zones. Data analysis uses the Leq formula and then also uses the chi-square method to determine the relationship between the two variables. The total number of vehicles passing on the Taman Siswa road during the measurement was 23,530. In this study, the significance level used was 0.05 with the result that the p value for two-wheeled vehicles was 0.008 and for four-wheeled vehicles was 0.2. By obtaining the results of the calculation of a p value of 0.008, this shows that only two-wheeled vehicles are correlate with noise. whereas for four-wheeled vehicles with a p value of 0.2 does not show any correlation

Abstract

Coconut leaf waste (Cocus nucifera), which contains various beneficial compounds, has not been utilized optimally by the community. Coconut leaves contain a valuable biomass of around 44,000 tonnes/ha to 67,000 tonnes/ha. This has the potential to be used as biochar. The research method used in this research is descriptive experimental research using coconut leaves as raw material for biochar briquettes using a pyrolysis carbonization process. This study used differences in the composition of starch which acts as an adhesive with 3 different variations, namely 2%, 4% and 6%. Based on the results of the ash content test and the calculation of the water content and density, the biochar briquettes in all samples complied with SNI 01/6235/2000.

Abstract

Keberadaan sampah plastik yang menggunung dapat membuat numpuknya populasi sampah di Indonesia. Sampah plastik memang tidak berbahaya secara langsung , namun sifat nya yang sulit terurrai di alam, membuat tanah menjadi tidak subuh, hingga menimbulkan rekaksi kimia. Ketika terkena panas sinar matahari membuat sampah plastic perlu diolah dan diminimalisir jumlahnya secara massif. Pengolahan sampah plastic yang umumnya dilakukan dengan cara pembakaran dirasa belum efektif karena hasil asap dengan kandungan CO2, CO, NOx, dan SOx yang dapat menyebabkan fenomena hujan asam jika terakumulasi di atmosfer dalam jumlah yang banyak itu pengolahan sampah plastik yang menghasilkan bahan bakar minyak juga tidak efisian karena tidak semua jenis plastic dapat diolah menjadi bahan bakar minyak dan melalui proses pembakaran dimana dapat menghasilkan gas buangan CO2, CO, NOx, dan SOx dengan akumulasi gas buangan yang lebih besar ketimbang hasil bahan bakar minyak yang diperoleh. Alternatif pengolahan sampah plastik yang ramah lingkungan dan low emission carbon perlu digerakkan demi mendukung program SDGs ke 13 (penanganan perubahan iklim) dan 14 (menjaga ekosistem laut). Salah satu cara yang dapat dilakukan ialah menggunakan bakteri Ideonela sakaiensis dengan konsep hidrolisis rantai polimer menjadi senyawa yang lebih sederhana dan mudah diurai alam. Penerapan bakteri Ideonela sakaisensis dapat diaplikasikan pada sampah berjenis PET (polyethylene terephthalate) karena jumlahnya dan tingkat bahaya yang cukup tinggi. Penguraian sampah ini berkonsep pada tempat sampah sebagai inkubator biodegradasi dimana bakteri Ideonella sakaiensis mengurai plastik pada medium yang optimal sesuai karakteristik lingkungan hidupnya.
