Abstract

Solid waste management problems have become a common problem in Indonesia. Based on data from the Central Bureau of Statistics' Environmental Care Behavior Indicator in 2017, it shows that 58.32% of Indonesians do not sort their waste. Kalimantan Institute of Technology (ITK) is a campus that carries the concept of eco-campus. Waste segregation has been programmed, but in reality in the field, waste segregation is not running. Therefore, this study was conducted with the aim of knowing the preferences and participation of ITK academic community in waste segregation at ITK. The survey results showed that out of 380 respondents, although 90% had seen posters about waste segregation at ITK, only 57.6% stated that they had done waste segregation at ITK, which was mostly based on the factor of facilitating management both by ITK and at the landfill. For the other 44.2% of respondents who do not or only sometimes do waste segregation, it was found that the biggest factor that made them do so was based on the desire to segregate at the beginning, but when opening the trash can, the waste inside was already mixed.

Abstract

Indonesia merupakan salah satu negara penghasil cengkih terbesar di dunia, dengan produksi perkebunan rakyat rata-rata 135,27 ribu ton. Sebagian besar hasil cengkih dimanfaatkan dalam industri rokok, sementara limbahnya seperti daun dan ranting belum dimanfaatkan secara optimal. Faktanya, daun cengkih mengandung senyawa bioaktif utama berupa eugenol yang memiliki nilai ekonomi tinggi dan digunakan secara luas dalam industri farmasi, kosmetik, pangan, dan produk kimia antara. Prarancangan pabrik kimia ini bertujuan untuk menentukan kapasitas produksi dan seleksi proses pada pendirian pabrik eugenol berbahan dasar daun cengkih. Pabrik eugenol dari daun cengkih ini direncanakan di Kawasan Industri JIIPE (Java Integrated Industrial and Ports Estate), Kabupaten Gresik, Jawa Timur akan beroperasi secara kontinyu selama 330 hari selama 24 jam pada tahun 2025 dengan kapasitas produksi 8.000 ton/tahun untuk memenuhi pasar ekspor. Metode yang digunakan untuk penentuan seleksi proses adalah grading (penilaian). Berdasarkan hasil grading, dipilih proses hydro-steam distillation dengan total penilaian 440 bersama reaksi saponifikasi reagen NaOH dan netralisasi reagen H2SO4. Tahap awal persiapan sintesis eugenol dilakukan dengan memotong daun cengkih kering kecil-kecil (± 2 cm), kemudian disuling untuk diambil minyak atsirinya dengan metode hydro-steam distillation. Eugenol yang terkandung dalam minyak atsiri diambil melalui reaksi penyabunan dan netralisasi yang terjadi di dalam Continuous Stirred Tank Reactor (CSTR). Metode pemurnian dilakukan berdasarkan perbedaan densitas dengan menggunakan dekanter. Efektivitas proses hydro-steam distillation ditinjau melalui aspek suhu, tekanan, waktu operasi, yield proses, dan kemurnian eugenol.
