Turbocharger merupakan kompresor sentrifugal digerakan oleh turbin yang diputar oleh asap gas buang kendaraan. Turbocharger diaplikasikan pada pembakaran dalam tekanan tinggi seperti mesi diesel untuk meningkatkan energi output dan efisiensi mesin. Pemasangan turbocharger dapat dilakukan pada kendaraan roda 2 pada kapasitas dan dimensi ruang bakar yang lebih besar. Literasi tentang pemanfaatan turbocharger pada kendaraan roda dua seperti motor sangat jarang ditemui dan sulit untuk mengetahui pengaruh penggunaan turbocharger pada sepeda motor. Pada sepeda motor udara intake yang panas dan memiliki tekanan tinggi dapat menimbulkan knocking pada pembakaran mengalami knocking. Penelitian ini bertujuan untuk memahami pengaruh perubahan ukuran diameter pada sudu kompresor terhadap sepeda motor CB150R. Penelitian ini meninjau perunaham performa daya dan torsi pada sepeda motor. Perubahan diameter kompressor turbocharger berpengaruh terhadap emisi, daya dan torsi yang dihasilkan sepeda motor, dari pengujian yang dilakukan didapat hasil motor yang menggunakan turbocharger dengan ukuran kompresor standart lebih tinggi HP dan Torsinya dari motor standar tanpa turbocharger. Pemasangan turbocharger pada sepeda menghasilkan performa yang bagus namun harus dilakukan penyesuaian spesifikasi kendaraan dan jenis turbocharger yang diaplikasikan.

One of the industries that need attention is the woven sarong industry. This industry produces liquid waste resulting from the coloring process. Indiscriminate disposal of waste will have a detrimental impact on the environment. Therefore, it is necessary to treat the waste first. The purpose of this study was to reduce the levels of COD and TSS in the colored liquid waste of the weaving sarong industry. This research uses the adsorption method using the adsorbent Zeolite activated by sulfuric acid. The concentration of sulfuric acid used was 2.5 N. The lowest COD removal percentage with a zeolite mass of 1 gram with a time of 60 minutes was 30.98% and the highest percent COD removal with a zeolite mass of 5 grams with a time of 180 minutes was 59.61% . The lowest percentage of TSS removal with a zeolite mass of 1 gram with a time of 60 minutes was 74.16% and the highest percentage of TSS removal with a zeolite mass of 5 grams with a time of 180 minutes was 94.05%.

Cooking oil is a basic need of sicety which has the main content oftriglycerides. Tryglicerides function of fry food. The use of cooking oil continuously can reduce the quality of cooking oil. There are several attempts to improve the acid number and perokxide value in cooking oil. One of the efforts is providing an adsorbent in the form of kepok banana peels (Musa paradisiaca L.) using cooking oil. Kepok banana peel contain cellulose which acts as an adsorbent. This study used H3PO4 as an activator and NaOH as ad delignification in manufacturing kepok banan peel biosorbent. The research method includes the preparation of the biosorbent, the delignification process, the activation of the biosorbent with an activator, and the application of the biosorbent to used cooking oil. The method used is the adsorption method. The adsorption method used variable perecentage of the kepok banana peel mass : 5%, 10%, 15%, 20%, 25% (m/m), and adsorption method contact times were 60, 120, 180, and 240 minutes. The analyzes tested were the acid number. The acid number value of used cooking oil decreased with the addition of the mass of the biosorbent and the length of contact time. The optimum result obtained after treatment on the acid number value were 6.507 mg KOH/gr with a variable mass of biosorben of 25% at a concatct time of 240 minutes.

The liquid waste of the food industry has recently increased. Therefore, when it is discharged into the waters, it will cause turbidity and can damage the ecosystem inside. One of the wastewater treatment techniques is absorption using biosorbents, one of which is made from coconut fiber to reduce the color intensity of the liquid waste. The purpose of this study was to determine the effects of the coconut fiber biosorbent on the color intensity, COD, and pH of the liquid waste of the food industry. In this research, the coconut fiber was delignified with a 2 M NaOH solution and then activated with a 3 N solution. The research variables consisted of the weight percentages of biosorbent by 1%, 2%, 3%, 4%, and 5%, and the contact time of 30 and 60 minutes with shaker stirring. Meanwhile, the most optimum results in COD removal happened at the addition of 4% for 60 minutes, from the initial COD of 1179 mg/L O2 to 780 mg/L O2 within the removal of 26.5%. The highest pH removal of 6.98 occurred in the variable addition of 1% for 30 minutes, whereas the lowest pH removal of 6.5

Kulit pisang diketahui mempunyai kemampuan dalam menyerap logam berat khususnya logam kadmium karena menghasilkan persen penyerapan tertinggi. Tujuan studi literatur yaitu untuk mengetahui aktivator terbaik pada adsorben, hubungan waktu kontak dengan persen penyerapan logam kadmium, dan hubungan massa adsorben dengan persen penyerapan logam kadmium. Aktivator yang digunakan pada studi literatur ini adalah HCl, H2SO4, HNO3, NaOH, KOH, dan H3PO4. Karbon aktif yang terbaik dari studi literatur didapatkan pada suhu karbonasi 300-500 ̊C dengan menggunakan aktivator HCl, sedangkan untuk biosorben hasil terbaik didapatkan pada suhu 75-100 ̊C dengan aktivator NaOH. Hasil terbaik pada karbon aktif didapatkan persen penyerapan sebesar 98,35% dengan massa 0,8 gram dan waktu kontak 90 menit, sedangkan pada biosorben didapatkan persen penyerapan sebesar 99,21% dengan massa 15 gram dan waktu kontak 3 menit. Dapat disimpulkan bahwa biosorben efektif digunakan dalam penyerapan logam kadmium dibandingkan karbon aktif.

Liquid waste has a component containing water that has been mixed with chemical compounds. One example of liquid waste containing chemical compounds is wastewater from a food coloring industry. The liquid waste of the food coloring industry has a very strong color density so that it has a negative impact on the environment, therefore it is necessary to treat liquid waste in order to meet the quality standards of wastewater in accordance with East Java Governor Regulation number 72 of 2013. The purpose of this study was to determine the effect of adding dose of coagulant and mass of biosorbent on percent color removal in food coloring industrial wastewater. The results showed that the addition of 35% coagulant and 13% biosorbent resulted in 97% optimal removal of color.

Oil content in the water that exceeds the threshold can pollute the environment if disposed of directly without waste treatment. This study conducted a case study of engineering waste treatment containing 1% oil using the Dissolve Air Flotation (DAF) method through coagulant and flocculant pre-treatment. The independent variable used in this study is pressure and residence time, where the pressure variable consists of 0.6, 0.8, 1, 1.2, and 1.4 bar, while the residence time variables comprised 5, 15, 30, 45, and 60 minutes. This study obtained the maximum pressure and residence time, namely at a pressure of 1.4 bar and a residence time of 60 minutes; the highest oil removal was 98.32%. Turbidity removal was 92.31% in 1% of engineering waste for engineering destruction.
