Abstract

Antibacterial activity test Staphylococcus aureus and Salmonella typhihas been performed by microencapsulation product of rogo essential oil (Premnaserratifolia Linn). This study aims to determine rogo oil activity test and microencapsulation results as antibacterial S. aureus and S. typhi. The results of antibacterial activity of rogo liquid oil to S. aureus and S. Typhi bacteria showed different inhibitory power of each concentration variation of 12.5%, 25%, 50% and 100% with 100% concentration as the best inhibitor for both bacteria. While the antibacterial activity test of S. aureus and S. typhi from microencapsulated rogo oil: maltodextrin showed the difference of each variation of concentration 1:10; 1:12; 1:14; 1:16 and 1:18 with a 1:14 composition of S. aureus and 1:18 in S. typhi as the best ratio of activity power. The antibacterial activity test between liquid rogo oil and microencapsulated result shows the difference, but it can be concluded that the inhibitory power of rogo oil from microencapsulation is more inhibited than 100% rogo oil.

Abstract

Nitration of methyl ester from mahogany oil (Swietenia mahagoniLinn) can be produced by Methyl Ester Nitrate (MEN), an additive that is useful for increasing Cetane Numbers in diesel fuel. This study aims to determine the yield of MEN that can be produced from mahogany seed oil after esterification, trans-esterification, and nitration and to identify the MEN compounds produced. Mahogany oil is obtained by pressing mahogany seeds and then degumming to remove the gum. Mahogany oil-free gum is esterified using methanol with the mole ratio of oil: methanol (1: 6), then trans-esterified, also using methanol with mole ratio (1:15) and a methyl ester is obtained. Then the methyl ester was nitrated with HNO3, sulfuric acid, and acetic anhydride to obtain a translucent reddish colored MEN product with a yield of 24.99%. The success of the synthesis was shown by the FTIR spectrophotometer in the presence of absorption at 1550 cm-1 which indicated the presence of the C-ONO2 group, the absorption at 1365 cm-1 indicated the presence of the NO2 group, and at 1118 cm-1 indicated the presence of the C-N group. The reaction mechanism that occurs during the predicted nitration reaction is an electrophilic substitution reaction and nucleophilic addition.

Abstract

The synthesis of methyl ester nitrate (MEN) from ketapang oil (Terminalia catappa L.) have been carried out. This study aims to determine the yield and the characteristics of MEN. In this study, ketapang seed oil was obtained from the soxhlet extraction process followed by an evaporation process to separate the oil from the solvent. MEN can be produced from ketapang seed oil by esterification to convert all of FFA became ester, followed by transesterification that intended to produce ester from triglycerides and nitrationthat is reaction of esther and HNO3 to create MEN. Evaporated oil is esterified using methanol with a mole ratio of oil: methanol (1: 6), then the transesterification process using methanol with a mole ratio (1:15) gives a yield of 86%. The transesterification product was then nitrated using HNO3 and H2SO4 for 4 hours with a yield of 83%. Characterization of methyl ester using GC-MS characterization showed the presence of methyl palmitoleate (C17H32O2), methyl palmitate (C19H34O2), methyl oleate (C19H36O2), methyl 13-octadecanoic (C19H36O2), methyl stearate (C19H38O2), and methyl 18-nonadecanoic (C21H42O2). Characterization MEN using a FTIR spectrophotometer showed the presence of a C-ONO2 group at wave number 1550 cm-1, NO2 group at wave number 1365 cm-1 and a C-N group at wave number 1118 cm-1. It shows that MEN can be synthesized from ketapang seed oil.

Abstract

Implementasi kurikulum merdeka belajar dapat dilakukan dengan kerjasama antara pihak Universitas dan SMA sederajat dalam mencapai cita-cita kebijakan merdeka belajar yaitu mewujudkan pendidikan berkualitas yang berfokus pada pengembangan kompetensi dasar dan pendidikan karakter sesuai profil pelajar Pancasila. Salah satu metode untuk merealisasikan pendidikan yang berkualitas adalah melalui proses metode ilmiah yang dapat dilakukan siswa dalam pembelajaran kimia dengan sarana laboratorium kimia. UPT Laboratorium Terpadu Unit Laboratorium Kimia UHO melakukan kerjasama dengan MA Asy-Syafi’iyah Kendari dalam rangka memberikan pengalaman kepada siswa tentang bagaimana melakukan praktikum di Laboratorium sebagai implementasi kurikulum merdeka belajar. Metode yang digunakan dalam kegiatan ini adalah metode ekspositori (ceramah) dan demonstrasi (praktikum), serta evaluasi menggunakan pre-test dan post-test. Setelah pelaksanaan kegiatan pengabdian ini dapat disimpulkan bahwa kegiatan pengabdian ini berjalan dengan baik dan memberikan manfaat bagi para siswa-siswi MA Asy-Syafi’iyah Kendari sebagai peserta dalam menambah pengetahuan tentang materi praktikum pengenalan alat bahan, pembuatan larutan dan reaksi asam basa. Hal tersebut dapat terlihat dari hasil analisis n-Gain sebesar 0,32 dimana nilai tersebut masuk dalam kategori lompatan nilai sedang yang menunjukkan bahwa pelatihan cukup memperlihatkan dampak yang signifikan.
