Abstract

This study aims to obtain bioethanol according to the Indonesian National Standard (SNI) 7390:2012, obtain Gasohol according to the RON (Research Octane Number) standard in Pertalite, and produce alternative fuels that are more environmentally friendly. The bioethanol production process includes hydrolysis, fermentation, distillation, and adsorption, with Saccharomyces cerevisiae to ferment sugar in pineapple skin into ethanol with a content of 59.62% from a 5-day fermentation process with 4% Saccharomyces cerevisiae, 0.5% urea, 0.5% NPK. Bioethanol is then mixed with Pertalite in the composition of E5 (5 ml of bioethanol mixed with 95 ml of Pertalite) to E25 (25 ml of bioethanol mixed with 75 ml of Pertalite), lowering the flash point of the mixture from 29.8°C (E5) to 28.0°C (E25), increasing the density from 0.7239 gr.(cm3)-1 (E5) to 0.7250 gr.(cm3)-1 (E25) and the viscosity from 0.41 cSt (E5) to 0.49 cSt (E25). Still, the octane number (RON) tends to be stable at 91.4-95.6. As a result, the bioethanol content is close to SNI 99.5%, the bioethanol-Pertalite mixture improves several parameters but lowers the flash point, and the E25 mixture meets the RON standard of 95.6 for Pertalite.

Abstract

ABSTRAK Sebagai tahap awal dalam siklus hidup tanaman kelapa sawit (Elaeis guineensis Jacq.), praktik pembibitan kelapa sawit menjadi aspek penting yang memerlukan evaluasi lebih dalam. Pemahaman mengenai dampak lingkungan pada fase pembibitan adalah kunci untuk merancang strategi pengelolaan yang berkelanjutan, mengurangi kerusakan ekosistem, dan mencapai keseimbangan antara produksi dan konservasi alam. Penelitian ini bertujuan untuk menganalisis dampak lingkungan pembibitan kelapa sawit di Unit Pembibitan Kelapa Sawit (UPKS) Politeknik Negeri Lampung menggunakan pendekatan penilaian daur hidup atau life cycle assessment (LCA). Studi ini difokuskan pada penilaian daur hidup gate-to-gate yang dilaksanakan dari Oktober hingga Desember 2023. Data dikumpulkan melalui kunjungan lapang dan wawancara dengan pengelola UPKS. Ruang lingkup LCA dimulai dari penerimaan kecambah hingga bibit siap salur. Permodelan dampak lingkungan menggunakan openLCA versi 2.0.3 dengan metode CML-IA baseline dan database pendukung Agribalyse v3.0.1. Hasil penelitian menunjukkan bahwa secara umum pembibitan kelapa sawit memberikan dampak lingkungan yang tidak signifikan. Kontribusi dampak lingkungan terbesar berasal dari dampak sekunder, khususnya marine aquatic ecotoxicity sebesar 190.52122 kg 1,4-DB eq. dan abiotic depletion (fossil fuels) sebesar 5.65733 MJ. Dampak primer potensi global warming (GWP100a) sebesar 0.27033 kg CO2 eq. yang dominan berasal dari penggunaan polybag dan potensi human toxicity sebesar 0.08227 kg 1,4-DB eq. Upaya pengurangan dampak lingkungan dapat dilakukan dengan penggunaan pot tray yang dapat digunakan berulang kali atau alternatif polybag dari bahan organik, kombinasi pupuk anorganik dan pupuk organik untuk mengurangi dosis pupuk anorganik, dan mengurangi laju evapotranpirasi dari tanaman dan media tanam dengan penggunaan mulsa organik dan media tanam yang mengandung bahan organic. Kata kunci: dampak lingkungan, kelapa sawit, LCA, pemanasan global, pembibitan ABSTRACT As the initial stage in the oil palm (Elaeis guineensis Jacq.) plant life cycle, oil palm seedling cultivation becomes a crucial aspect that requires in-depth evaluation. Understanding the environmental impact at the seedling phase is critical to designing more sustainable management strategies, reducing ecosystem damage, and achieving a balance between production and conservation. This study aims to present an environmental impact analysis of oil palm seedling cultivation at the Oil Palm Nursery Unit (UPKS) of Politeknik Negeri Lampung using the life cycle assessment (LCA) approach. This study focuses on a gate-to-gate life cycle assessment conducted from October to December 2023. Data were collected through field visits and interviews with UPKS managers. The LCA scope covers from seed acceptance to ready-to-distribute seedlings. Environmental impact modeling used openLCA version 2.0.3 with the CML-IA baseline method and supporting database Agribalyse v3.0.1. Results indicate that oil palm seedling nursery generally has an insignificant environmental impact. The most substantial contributions come from secondary impacts, mainly marine aquatic ecotoxicity at 190.52122 kg 1,4-DB eq. and abiotic depletion (fossil fuels) at 5.65733 MJ. Primary impacts are potential global warming (GWP100a) at 0.27033 kg CO2 eq., primarily from polybag use, and potential human toxicity at 0.08227 kg 1,4-DB eq. Efforts to mitigate environmental impacts can be achieved by using reusable pot trays or organic material-based polybags as alternatives, coupled with a combination of inorganic and organic fertilizers to reduce the dosage of inorganic fertilizers. Additionally, curtailing evapotranspiration rates from plants and growing media can be accomplished by employing organic mulch and growing media enriched with organic matter. Keywords:  environmental impact, global warming, LCA, nursery, oil palm

Abstract

ABSTRAK Perkembangan industri tekstil menjadi salah satu penyumbang terbesar limbah zat warna ke lingkungan yang berdampak pencemaran terhadap sumber air. Hal ini dikarenakan melalui hasil pengamatan langsung di lapangan kondisi air limbah yang dibuang masih berwarna pekat dan berbau. Penelitian ini bertujuan untuk mempelajari kinetika adsorpsi zat warna metilen biru menggunakan adsorben grafen oksida yang disintesis dari limbah baterai. Metode hummer digunakan dalam sintesis grafen oksida melalui penambahan asam sulfat. Studi kinetika adsorpsi dilakukan pada konsentrasi metilen biru 10-50 ppm serta variasi waktu adsorpsi 5-25 menit. Kondisi optimum diperoleh pada pada konsentrasi metilen biru 30 ppm dengan waktu 25 menit. Mekanisme adsorpsi yang terjadi mengikuti model Langmuir nilai R2 sebesar 0.92522 dengan nilai Qm= 99.1 mg.g-1 dan nilai K=0.325. Kata kunci: adsorpsi, graphene oxide, jurnal, teknik lingkungan ABSTRACT  The development of the textile industry is one of the main sources of dye waste I the environment, which means that the discharged wastewater is still concentrated and smelly when observed directly on the ground, thus contributing to water pollution. The aim of this study is to determine the relationship between the concentration of methylene blue dye and the adsorption time and to determine the adsorption isotherm. For the synhesis of graphene oxide, the hummer’s method was used where graphite wes recombined with H2SO4 sulfuric acid and the adsorbed solution was measured using UV-Vis spectrophotometer. Graphene oxide acted as an adsorbent by adsorbing methylene blue and the result showed that he optimum time and concetration was acheieved at a 30 ppm and 25 minutes.  The adsorption mechanism aligns with the Langmuir model, demonstrated by an R2 value of 0.92522, a Qm value of 99.1 mg.g-1, and a K value of 0.325. Keywords: adsorption, environmental engineering, graphene oxide, journal
