Sampah plastik sangat sulit terurai dibutuhkan waktu yang lama untuk dapat terurai.Tujuan dari penelitian ini adalah untuk membuat batako yang, ringan, mudah dikerjakan dengan sistem pemasangan interlock dan ramah lingkungan dengan menggunakan bahan komposit limbah botol plastik kemasan air minum.Penelitian dilakukan dengan cara membuat batako menggunakan bahan tambah material komposit plastik. Komposisi campuran untuk biji plastik 50%, 70% dan 90% terhadap volume pasir dan untuk campuran serat plastik 30% dan 50%. Dari hasil pengujian, didapatkan kuat tekan batako campuran biji plastik dengan komposisi 50%, 70% dan 90% berturut turut yaitu 63,88 kg/cm2, 56,28 kg/cm2, dan 51,22 kg/cm2 sedangkan untuk berat isinya berturut-turut yaitu 1503 kg/m3, 1482 kg/m3 dan 1341 kg/m3. Untuk kuat tekan batako dengan campuran serat limbah plastik dengan komposisi campuran 30% yaitu sebesar 30,13 kg/cm2 dengan berat isi 1437 kg/m3 dan campuran 50% menghasilkan kuat tekan sebesar 19,75 kg/cm2, dengan berat isi 1267 kg/m3. Batako dengan campuran biji plastik masuk dalam mutu bata beton pejal kelas II-III, sedangkan untuk batako dengan serat plastik masuk dalam kelas IV. Berdasarkan berat isi, batako yang dihasilkan masuk dalam kelas beton ringan.

Abstract. Bricks is still one of the walls building materials that are widely used in North Sulawesi, specifically in Manado City, Bitung City and Tomon City. The purpose of this study was to determine the characteristics of local bricks in Manado City, Bitung City and Tomohon City. The characteristics of the bricks in question are the dimensions and compressive strength of the bricks. This research was conducted by taking samples of pejal bricks from several brick production sites in Manado City, Bitung City and Tomohon City. The bricks taken to be used as samples are pressed bricks. Brick samples that have been taken from these three cities, are then tested in the laboratory. From the test results in the laboratory, it is known that for the dimensions of the brick samples taken in Manado City and Bitung City, it has not met the brick size standards based on SNI 03-0349-1989, namely the brick length of 390 mm (+3&-5), width 190 mm (+2) with a thickness of 100 mm. The bricks taken from Tomohon City for length mostly meet the existing standards with width and thickness that have not met but are close to the standard. The results of the compressive strength test for brick samples are only brick samples in Malalayang sub-district that meet the standards, including quality IV-III of 30.67 kg / cm2. None of the brick samples taken from Bitung City and Tomohon City met the compressive strength standards. Keywords: Brick, Building Material, SNI 03-0349-1989
