Pengaruh Penambahan Serat Limbah Plastik HDPE terhadap Kuat Tekan pada Mortar

Mortar merupakan bahan konstruksi yang umum digunakan pada gedung maupun jalan. Beberapa konstruksi yang menggunakan mortar antara lain Lane Concrete (LC), spesi, perekat bata ringan, plester dinding, acian instan, pemasangan kramik, dan lain-lain. Serat limbah plastik HDPE (High Density Polyethylene) pada penelitian ini adalah bahan campuran sebagai pengikat dan pengganti semen. Plastik HDPE merupakan salah satu jenis plastik yang jika dilihat secara visual tergolong pekat, dimana pemakaian jenis plastik ini biasanya digunakan untuk botol minuman. Jenis plastik HDPE mudah untuk di daur ulang. Penelitian ini diharapkan dapat mengurangi jumlah limbah plastik yang ada di Indonesia. Tujuan penelitian ini adalah untuk mengkaji pengaruh pencampuran serat limbah plastik HDPE dengan variasi terhadap kuat tekan dan berat mortar. Serat yang digunakan sebanyak 0%, 2%, 4%, dan 6% terhadap berat semennya. Penelitian ini dilakukan untuk memperoleh kuat tekan mortar pada umur 7 hari dan 28 hari dengan menggunakan benda uji kubus dengan dimensi 15 cm × 15 cm × 15 cm. Hasil pengujian menunjukkan bahwa kuat tekan tertinggi untuk mortar serat pada variasi serat 2% di umur 28 hari yaitu sebesar 14,47 MPa. Kuat tekan mortar pada umur 7 dan 28 hari berturut-turut mengalami kenaikan sekitar 11%. Sedangkan pada penambahan serat, kuat tekan mortar mengalami penurunan seiring dengan semakin banyaknya campuran serat. Mortar serat mengalami penurunan berat dari 7696 gram menjadi 7640 gram, 7422 gram, dan 7280 gram, masing-masing untuk 2%, 4%, dan 6% serat pada umur 28 hari. Mortar is a construction material commonly used in building and road infrastructure. Some constructions that use mortar include Lane Concrete (LC), species, light brick adhesives, wall plaster, mechanical installation, and others. HDPE plastic waste fiber (High density polyethylene) in this study is a mixture of materials as binders and cement substitutes. HDPE plastic is one type of plastic that when viewed visually is classified as concentrated, where the use of this type of plastic is usually used for beverage bottles. The HDPE plastic type is easy to recycle. In 2015, global plastic waste in the world was recorded at 2.5 billion tons per year, so this research is expected to reduce the amount of plastic waste in Indonesia. The purpose of this study was to analyze the effect of mixing HDPE plastic waste fibers on compressive strength and mortar weight. This HDPE variations of 0%, 2%, 4%, and 6% is used from the weight of the cement. This study was carried out to obtain the compressive strength at the ages of 7 days and 28 days using cube specimens with dimensions of 15 cm × 15 cm × 15 cm. Based on the results of the test, the highest compressive strength for mortar at of 2% fiber variation at 28 days is 14.47 MPa. The compressive strength of mortar at the age of 7 and 28 consecutive days increased by 11%.

Fuel Pyrolysis

Indonesia is one of the biggest plastic waste production in the world. The government targets to reach 20% for recycling plastic waste in 2019. One alternative to manage plastic waste is using pyrolysis to produce fuel. Pyrolysis is used to degrade the plastic long chain of polymer molecules into smaller molecules. All type of plastic except polyvinyl chloride (PVC) were used in this study to produce fuel. For the purpose, experiment factorial design was used for the optimisation plastic type, residence time, and temperature to maximise the yield of liquid products of the pyrolysis process. In this study 2k factorial design was used for each factor. The result shows that the pyrolysis process used is able to produce diesel like fuel in low temperature.

Asian Rice

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.

Optimal Data Analysis

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.

AbstractPlastic waste needs attention because it can cause serious problems if not managed properly. Of the various types of plastics, the most widely disposed of to the environment are Polypropylene, Polyethylene Terephthalate, and High-Density Polyethylene which are usually in the form of plastic bags and bottles. This research was conducted to make bricks made of plastic as an alternative material for infrastructure that is economical, strong, and durable, which is seen based on the compressive strength value based on its type, namely PP, PET, and HDPE plastic bricks. The compressive strength testing phase is carried out three times in each type. The selling price of plastic bricks is determined by the Markup pricing method. The process of plastic brick making includes collecting plastic waste, washing, drying, chopping, melting, and printing. Based on the research results, the plastic bricks produced from the types of PET, HDPE, and PP are in the form of blocks with a size of 19 cm x 10 cm x 6.5 cm, where the PET type brick requires 5.1 kg of waste, 3.6 kg of HDPE type, and the type of PP as much as 3 kg. The compressive strength test values for PP, PET, and HDPE plastic bricks have met the compressive strength standards based on SNI 15-2094-2000, with the highest average compressive strength test values found in PP plastic bricks of 246 kg/cm², plastic bricks HDPE type 166 kg/cm², and plastic brick type PET 98.7 kg/cm². The selling price of plastic bricks without including the purchase price of plastic as raw material for making plastic bricks (Scenario I) for PP plastic bricks costs Rp1.907,00/brick, PET types Rp3.024,00/brick, and HDPE types Rp3.464,00/brick. While the selling price of plastic bricks by entering the purchase price of plastic as raw material for making plastic bricks (Scenario II) for PP plastic bricks Rp2.867,00/brick, PET type Rp4.624,00/brick, and HDPE type Rp3.944,00/brick.Keywords: Compressive Strength, Markup Pricing, Plastic Brick.
