Abstract

This study evaluated the impact of using turpentine oil as an additive in gasoline fuel mixtures on exhaust emissions. Turpentine oil, obtained from pine tree resin, has flammable properties and high oxygen content, which is believed to be able to improve the combustion process in the engine. In this experiment, gasoline was mixed with turpentine oil in various concentrations (0%, 5%, 10%, 15% and 20%) and tested on a single-cylinder 4-stroke gasoline engine with engine speeds (1500, 3000, 4500 and 6000) rpm. The emissions analyzed included carbon monoxide (CO), hydrocarbons (HC), carbon dioxide (CO₂), and oxygen (O2). The results showed that the addition of turpentine oil in certain amounts could reduce CO and HC emissions at engine speeds above 4000 rpm due to more perfect combustion, although accompanied by a slight increase in CO2 and O2 emissions at engine speeds above 4000 rpm. Overall, turpentine oil shows potential as an environmentally friendly alternative additive in reducing emission pollution from gasoline fuel.

Abstract

At-Tajdid salah satu pondok pesantren (ponpes) modern yang menyiapkan Muslim Berkemajuan sebagai kader persyarikatan maupun kader bangsa yang berintegritas, sebagai penyelenggara pendidikan di dalam pondok pesantren tentunya terdapat fasilitas pendukung proses belajar mengajar santri/santriwati yang saat ini berjumlah 215 orang. Untuk akses masuk-keluar lingkungan ponpes terdapat gerbang terbuka karena belum/tidak ada pintu yang membatasi akses ke dan dari lingkungan pondok pesantren. Selama ini, siapapun bebas masuk/keluar lingkungan ponpes, baik siang maupun malam. Dengan kondisi seperti itu, maka permasalahan yang dihadapi mitra adalah kerawanan lingkungan terhadap terjadinya kejahatan, utamanya kasus pencurian di lingkungan pondok pesantren. Hal ini disebabkan tidak adanya kendali akses di pintu gerbang. Berdasarkan situasi dan kondisi yang dihadapi mitra tersebut, maka solusi dan target luaran yang ditawarkan dalam program PkM ini yaitu Mitra dibuatkan pintu atau portal yang dipasang pada gerbang pondok dengan sistem buka-tutup pintu atau portal dibuat semi-otomatis bertenaga surya guna membatasi akses masuk/keluar lingkungan pondok pesantren. Dengan adanya pembatasan tersebut, dapat memberikan rasa aman dan nyaman bagi seluruh penghuni di lingkungan pondok pesantren, sehingga konsentrasi proses belajar mengajar meningkat.
