Bahan yang terbuat dari asbestos sangat mengganggu kesehatan terutama yang berhubungan dengan paru-paru manusia begitu juga pemerintah juga melarang penggunaan asbestos sebagai bahan rem kendaraan. Bahan yang terbuat dari logam juga mengganggu kesehatan dan suara bising. Tugas utama pada pad adalah untuk menghentikan laju kendaraan dengan halus tanpa menimbulkan guncangan. Perlu adanya indikator-indikator untuk perbaikan sistem pengereman yang tidak mempengaruhi pada kendali kemudi pada saat terjadinya pengereman. Apa yang dimaksud dengan keausan adalah sebagian hilangnya material dari permukaan yang dipengaruhi oleh bahan yang bergesekan. Dari pengujian kekerasan Spesimen brake pads yang diperlakukan pirolisis temperatur 200°C dengan nilai yang tertinggi fraksi volume 50% : 50 % menggunakan alat Shore Durometer = 77 HD, terendah pirolisis fraksi volume 30%:70% = 49 Hard Durometer. Hasil uji keausan yang paling rendah yaitu campuran 50% arang hasil pirolisis dan 50% epoxy : 0.02404 mm 3 /kg.m, tertinggi fraksi volume 30% : 70% = 0,06598 mm 3 /kg.m.

“…Acid compounds contained in liquid smoke can inhibit the formation of spores and microbial growth in food products [13][14][15][16]. Meanwhile, the phenolic compounds of liquid smoke have antibacterial and antioxidant properties, and potential in exhibit microbial activity against various microorganisms such as bacteria [17,18]. This study aimed to determine the physicochemical characteristics, antioxidant and antibacterial activities of liquid smoke derived from MS and CPH biomass.…”

This study aimed to analyze the physicochemical characteristics, antioxidant and antibacterial activities of liquid smoke derived from mixed sawdust (MS) and cocoa pod husks (CPH) biomass. The liquid smoke formed by pyrolysis of MS and CPH biomass (Theobroma cacao L.) has the physical characteristics of brown color, transparrent, has floating solids, and has an acidic pH of 3.79 for MS and 5.43 for CPH. The results of the antibacterial assay of both liquid smokes by agar diffusion method against 3 pathogenic bacterial isolates; Escherichia coli FNCC 0091, Staphylococcus aureus FNCC 0047 and Salmonella typhimurium FNCC 0150 showed positive results with the formation of clear zones around the test discs. Antioxidant activity assay showed that liquid smoke derived from the biomass of MS had an IC50 value of 0.112 mg/mL, more potential than liquid smoke derived from the biomass of CPH, which was 2.060 mg/mL. Liquid smoke chemical composition analyzed by Gas Chromatography-Mass Spectrometry method showed that liquid smoke derived from MS biomass was dominated by acetic acid (64.64 %), phenols (12.08 %) and acetone (5.78 %), while the liquid smoke derived from CPH biomass was dominated by methylamine (37.26 %), acetic acid (24.61 %) and acetone (19.89 %). The acetic acid, phenols, methylamine and acetone content in both liquid smokes thought to play an important role on its antioxidant activities and inhibition of bacterial growth. HIGHLIGHTS Pyrolysis uses biomass as raw material in the form of mixed sawdust from the home furniture industry and CPH which are a by-product of the chocolate processing industry The liquid smoke obtained from the pyrolysis of both types of biomass has a unique composition and has antibacterial and antioxidant properties The liquid smoke has the potential to be applied as a preservative in food products GRAPHICAL ABSTRACT

“…The thermal decomposition of organic components without oxygen in producing liquids, gases, charcoal, or pyrolysis can be described as the thermal degradation of materials without oxygen [9]. The process is carried out at a relatively high temperature, around 300-550°C, within 4-7 hours, depending on the method of manufacture and the raw materials used with limited air or even in the absence of air [10,11]. The main products resulting from pyrolysis are gas (fuel/gas), liquid (bio-oil) and solid (charcoal/charcoal) [12][13][14][15].…”

Biomass is a good resource for renewable energy. Biomass can be converted into bio-fuel (bio-oil) through a catalytic fast pyrolysis process. Previous studies only used single feedstock biomass as raw material for bio-oil production. In this study, bio-oil production is based on a multi-feedstock biomass waste consisting of rice husk, sugar cane bagasse, and palm oil empty fruit bunch. The mixture of biomass waste as a raw material is expected to enhance the yield and quality of the bio-oil produced. This study aimed to investigate the bio-oil products obtained from catalytic pyrolysis of the biomass waste mixture. Mixture Design from Design Expert was used to study the effect of biomass composition on the bio-oil products. Each biomass, i.e., rice husk, sugar cane bagasse, and palm oil empty fruit bunch, was previously chopped and sieved into a uniform 60 mesh. The pyrolysis process was conducted at 500°C with an N2 flow rate of 3 L min-1. The mixture of biomass waste husks contains more phenolic compounds than single-feedstock. The chemical characterization also showed that the multi-feedstock bio-oil compound was dominated by aldehydes, esters, and phenolic compounds.
