The possibility of using plastic waste to manufacture hybrid bio-composite materials with the dry husk of Asian rice (Oryza sativa L.) is investigated. The most polluted and unsustainable plastic waste is High-Density Polyethylene (HDPE) due to its single-use, which decreases in quality if it is reused is selected. The mixtures chosen are local natural fiber and easy to find, potentially a preliminary study of a composites building material. Furthermore, to improve the tensile properties of this hybrid bio-composite material, an additional organic filler is used, such as rice husk (Oryza sativa L.) in a combination of 10%, 12%, and 15%. Samples for this study were processed using the hot press methods based on ASTM D882. Tested for tensile strength, modulus young, yield stress, and elongation is carried out to see an increase in the performance of the biocomposite material. The test results show that the best tensile properties are samples with 12% rice husk, resulting in excellent sample compatibility proofed by Scan Electron Microscopy to study bio-morphological composites. This project has shown that the composites based on natural fiber will be potential building materials due to their improved tensile properties.

Indonesia menduduki posisi ke dua setelah cina penghasil sampah plastik terbesar di dunia. Dimana salah satu limbah plastik tersebut adalah HDPE (High Density Polyethylene). Sedangkan plastik merupakan produk hasil pengolahan minyak bumi yang dapat direcycle ke bentuk semulanya karena bahan baku pembuatan limbah plastik adalah nafta yang merupakan salah satu unsur dari minyak bumi. Salah satu solusi yang diperlukan adalah recycle dengan mengubah limbah plastik menjadi bahan bakar dengan proses pirolisis. Pirolisis merupakan salah satu proses terbaik dari recycle limbah plastik, dengan pertimbangan memahami sifat limbah plastik HDPE. Penelitian ini menggunakan alat pirolisis dengan variable suhu proses yaitu 300⸰C, 325⸰C, dan 350⸰C, waktu proses pirolisis yaitu 2 dan 4 jam. Dari proses pirolisis diperoleh hasil volume bahan bakar diesel yaitu pada suhu 300⸰C sebanyak 95 ml, suhu 325⸰C sebanyak 100 ml, dan suhu 350⸰C sebanyak 145 ml. Dari hasil analisa data optimal  untuk suhu dan waktu optimum proses pirolisis limbah plastik HDPE yaitu pada suhu 325⸰C selama 2 jam, bahan bakar diesel yang didapat memiliki kadar abu 0,044 (b/b), dan kadar air 0,031(%vol). ABSTRACTIndonesia is in second place after China, the largest plastic waste producer in the world. Where one of the plastic wastes is HDPE (High-Density Polyethylene). Meanwhile, plastic is a product of petroleum processing that can be recycled to its original form because the raw material for making plastic waste is naphtha, which is an element of petroleum. One solution that is needed to recycle by converting plastic waste into fuel by the pyrolysis process. Pyrolysis is one of the best processes for recycling plastic waste, with consideration of understanding the nature of HDPE plastic waste. This study used a pyrolysis tool with process temperature variables, namely 300⸰C, 325⸰C, and 350⸰C, the pyrolysis process time was 2 and 4 hours. From the pyrolysis process, the results of the volume of diesel fuel are at a temperature of 300 ⸰C as much as 95 ml, a temperature of 325 C as much as 100 ml, and a temperature of 350 ⸰C as much as 145 ml. From the results of the optimal data analysis for the optimum temperature and time of the HDPE plastic waste pyrolysis process, which is at a temperature of 325⸰C for 2 hours, the obtained diesel fuel has an ash content of 0.044 (w / w), and a moisture content of 0.031 (vol%).

Polymer Wastes

Rapid industrial development causes serious problem all over the world such as depletion of natural aggregates and creates enormous amount of waste material from construction and demolition activities. Quantities of polymer wastes also have been increased these recent years due to the boost in industrialization and the rapid improvement in the standard of living. In Malaysia, most of polymer wastes is abandoned and not recycled. This situation causes serious problems such as wastage of natural resources and environmental pollution. Polymer products such as synthetic fibers, plastics and rubber belong to petrochemical compound and not easily biodegradable even after a long period. One of the ways to reduce this problem is to utilize waste materials in the production of concrete. Use of these materials not only helps in getting them utilize in cement, sand, aggregate, concrete and other construction materials, it helps in reducing the cost of concrete manufacturing, but also has numerous indirect benefits such as reduction in land-fill cost, saving in energy and protecting the environment from possible pollution effects. An experimental research is made on the utilization of plastic waste, High Density Polyethylene (HDPE) as coarse aggregates in concrete with a percentage replacement of 10 %, 20 % and 30 %. The laboratory tests include slump test, compressive strength and water absorption were conducted in this research. The samples content 10 % of HDPE has better performance in term of strength.
