Abstract

Research has been carried out on the effect of using used cooking oil 6, 8 and 10 times usage on the % yield of methyl ester formation (biodiesel) using a homogeneous base catalyst of 0.6% mass NaOH. All used cooking oil samples were reacted with methanol with a reactant ratio of 1:5 % by mass. The transesterification reaction of each sample was carried out at 60°C for 40 minutes. The yield of used cooking oil samples for 6 times of use was 96.6%, while 8 and 10 times of use showed values ​​that were not much different, 96.4 and 96% by mass, respectively. Gas Chromatography (GC) and Mass Spectrocopy (MS) detected 14 peaks of the compound and that the 3 highest peaks indicated that the sample contained a methyl ester. Each peak of line 4 is methyl palmitate (C17H34O2) with an area of ​​36.66%, peak of line 6 is methyl oleate (C19H36O2), area of ​​55.7% and retention time of 17.92 minutes; the peak of line 7 is methyl nonadecanoate (C20H40O2) with an area of ​​4.41% and a retention time of 18.093 minutes.

Abstract

Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan pemahaman dan kesadaran siswa sekolah dasar terhadap pentingnya kebersihan tangan melalui pelatihan praktis pembuatan hand sanitizer alami berbasis bahan sederhana. Kegiatan dilaksanakan di SD Negeri 032 Balikpapan Utara oleh dosen dan mahasiswa Program Studi Teknik Pengolahan Migas sebagai wujud pelaksanaan Tri Dharma Perguruan Tinggi. Metode pelaksanaan meliputi tahap persiapan, penyampaian materi secara interaktif, demonstrasi pembuatan hand sanitizer, praktik langsung oleh peserta, serta evaluasi kegiatan. Sebanyak ±91 siswa mengikuti kegiatan dengan antusias dan terlibat aktif dalam seluruh rangkaian pelatihan. Hasil kegiatan menunjukkan bahwa peserta mampu memahami konsep dasar kebersihan tangan serta mempraktikkan pembuatan hand sanitizer alami secara mandiri dengan bimbingan tim pelaksana. Produk hand sanitizer yang dihasilkan memiliki karakteristik yang layak untuk penggunaan harian dan aman digunakan. Selain memberikan manfaat edukatif bagi siswa, kegiatan ini juga meningkatkan keterampilan komunikasi, kerja sama, dan kepedulian sosial mahasiswa. Secara keseluruhan, pelatihan ini efektif sebagai media edukasi kesehatan dan sains aplikatif bagi siswa sekolah dasar.

Abstract

Pemanfaat sampah limbah bawang merah (Allium Cepa L) berupa kulit luar bawang dan bonggolnya sebagai salah satu bahan baku alternatif pembuatan biodisel.Dari ketiga sampel minyak hasil ekstraksi limbah kulit bawang merah dengan sampel 10gr, 20gr dan 30gr,proses ekstraksi 3 sampel tersebut diekstraksi dengan pelarut Methanol dan n-Heksana hingga mencapai 1 siklus disetiap sampelnya dan disetiap pelarutnya. Setelah itu lakukan proses distilasi sebanyak 20 ml untuk memisahkan hasil minyak dengan pelarut.Nilai %Yield berturut-turut yaitu 24%, 14% dan 13,3% dengan menggunakan pelarut Metanol dan 16%, 8%, 19% dengan menggunakan pelarut n-Heksana.pH yang dihasilkan dari ketiga sampel yaitu 6. FFA yang dihasilkan pada sampel 1,2 dan 3 berturut-turut yaitu, 3%, 2,1% dan 1,7% dengan menggunakan pelarut Metanol. Dengan menggunakan pelarut n-Heksana Sampel 1 menghasilkan kadar FFA sebesar 1,4% dan sampel 2 menghasilkan kadar FFA sebesar 0,8% serta pada sampel 3 menghasilkan %FFA sebesar 0,6%.

Abstract

This community service activity is motivated by the importance of fostering social awareness and a spirit of sharing with the community, especially during the month of Ramadan. The Takjil on the Road: Sharing Together, Serving Together program aims to provide direct benefits to the community, especially road users who are still active before breaking the fast, while also increasing the social awareness of students. The method used in this activity is a participatory approach that actively involves lecturers and students in every stage of the activity, from planning, preparation, implementation, to evaluation. The activity was carried out by distributing takjil packages to the community at predetermined locations. The results of the activity showed a positive response from the community and increased participation and social awareness of students in social activities. This activity is a tangible form of higher education's contribution to the community and a means of social learning for students.
