Abstract

Abstrak Kebutuhan bahan bakar minyak di Indonesia, khususnya premium semakin meningkat, sedangkan ketersediaannya di alam semakin sedikit. Oleh karena itu, perlu dicari alternatif bahan bakar yang dapat diperbaharui, seperti Etanol. Etanol dengan kadar >96,5% v/v dapat digunakan sebagai campuran bahan bakar. Etanol dengan kadar >96,5% dapat dicapai dengan menggunakan metode distilasi adsorptif. Pada penelitian ini pemurnian etanol dilakukan menggukana dua cara yaitu distilasi sederhana dan distilasi adsorptif. Kadar awal sampel CIU A, CIU B dan CIU C berturut-turut adalah 9,92%, 44,60% dan 47,31% dengan menggunakan metode distilasi sederhana kadar etanol dapat meningkat menjadi 29,37%, 86,96% dan 90,81%. Meskipun metode distilasi sederhana dapat meningkatkan kadar etanol secara signifikan namun tidak dapat melampaui titik azeotropnya sehingga perlu adanya metode lain yaitu distilasi adsorptif dengan adsorben zeolit alam yang sudah teraktivasi. Dengan menggunakan metode distilasi adsorptif diperoleh kadar etanol tertinggi CIU A, CIU B dan CIU C berturut-turut sebesar 33,20%, 98,28% dan 99,22%. Kadar etanol tertinggi diperoleh saat pengambilan distilat ke-3 yaitu pada waktu 45 menit distilasi. Abstract The need for fuel oil in Indonesia, especially premium, is increasing, while its availability in nature is getting smaller. Therefore, it is necessary to look for alternative renewable fuels, such as Ethanol. Ethanol with a level of> 96.5% v / v can be used as a mixture of fuel. Ethanol with a concentration of> 96.5% can be achieved using the adsorptive distillation method. In this study, ethanol purification was carried out using two methods, simple distillation and adsorptive distillation. Initial levels of CIU A, CIU B and CIU C samples were 9.92%, 44.60% and 47.31% respectively using a simple distillation method. Ethanol levels could increase to 29.37%, 86.96% and 98.81%. Although a simple distillation method can significantly increase ethanol levels but cannot exceed its azeotropic point, it is necessary to have another method, namely adsorptive distillation with activated zeolite natural adsorbent. By using the adsorptive distillation method, the highest ethanol levels of CIU A, CIU B and CIU C were 33.20%, 98.28% and 99.22% respectively. The highest ethanol content was obtained when the third distillate was taken at 45 minutes distillation.

Abstract

About 780 million tonnes of fly ash are produced annually worldwide. The use of fly ash is still minimal, causing fly ash piles to increase. Based on this, a study was conducted on the extraction of iron from coal fly ash using HCl as a solvent. This study aims to determine the Fe content in fly ash extracted using HCl with variations in HCl concentration and extraction time. This research begins with the preparation of fly ash samples using an oven. Fly ash that has been prepared and extracted using HCl added with MIBK and EDTA was then characterized using XRF, FTIR and AAS. The results showed that the highest Fe content (11.48%) was obtained from the extraction using 9N HCl for 1 minute. The greater the concentration of HCl and the faster the extraction time, the more Fe extracted.

Abstract

During online learning, students are generally asked to study practicum procedures that have been provided by the lecturer, then they are given raw data from practicum results in the previous semester for analysis and preparation of practicum reports. Another method used is to provide demonstration videos or use digital applications such as virtual labs. In general, students can attend lectures smoothly and well, but many also say that this method is boring because there is almost no difference with theoretical classes. The object of the research is second semester chemistry students, which consists of 1 class of chemistry program and 1 class of chemistry education program. The research begins with a pretest, then students carry out the planned learning, then ends with a posttest and filling out a questionnaire. The project in the do lab at home practicum is specified to titrate a solution of vinegar with a solution of baking soda or vice versa. Each student prepares a buffer solution with various pH according to the instructions of sub-project 1, makes an acid-base indicator solution from natural materials according to the instructions of sub-project 3, and determines the RGB ratio of a buffer solution that has been given a natural acid-base indicator using the instructions of the sub-project.  In quantity, all students upload practicum videos, with a duration ranging from 8-15 minutes.  Based on the results of the practicum videos uploaded by students, the first creativity that can be seen immediately is the composition of video editing, such as sound quality, image quality, and the addition of information in the video. In this study, in general, it can be said that students are in the development stage for the fluency-brainstorming indicator.  Just like fluency indicators, flexibility indicators are also generally still in the developing stage, they still need help in taking new perspectives. Making videos, although not the main product, can train students' skills, including creative thinking. In detail, risk taking indicators are further divided into 2, namely risk taking-1 and risk taking-2. Most of the students are at the developing level for the risk taking-1 indicator.

Abstract

Desa Jawisari, yang merupakan salah satu desa diantara 16 desa yang berada di wilayah Kecamatan Limbangan Kabupaten Kendal, merupakan sentra penghasil gula aren tradisional. Namun, jumlah pengrajin yang cukup banyak ini ternyata belum mampu membawa gula aren menjadi salah satu komoditas utama Kabupaten Kendal karena sistem pengelolannya yang masih sangat tradisional. Kesalahan dalam proses pemanasan menyebabkan rendahnya kualitas gula aren yang dihasilkan, dimana intensitas warna yang tidak konsisten dan seringkali bahkan terlalu gelap. Selain itu, bentuk gula juga tidak rapi dengan ukuran yang tidak seragam. Oleh karena itu, dalam kegiatan pengabdian kepada masyarakat masyarakat ini akan dilakukan perbaikan proses pemanasan. Namun demikian, kegiatan pengabdian ini tidak hanya fokus pada perbaikan proses pemanasan nira saja, tetapi juga dilengkapi dengan penyuluhan dan pelatihan teknik penyadapan serta penyimpanan nira serta teknik pengemasan dan pemasaran. Kegiatan ini akan dilakukan secara sinergi antara mitra, Universitas Negeri Semarang selaku lembaga akademisi serta Pemerintah Daerah Kabupaten Kendal melalui Dinas Perindustrian, Koperasi, Usaha Kecil dan Menengah. Hal ini mengingat peran Pemerintah Daerah sebagai fasilitator terhadap keberlangsungan program ini sangat diperlukan, terutama untuk pemasaran gula aren. Harapannya, gula aren dapat menjadi salah satu produk unggulan Kabupaten Kendal, jika kualitasnya dapat ditingkatkan melalui kegiatan pengabdian kepada masyarakat ini.
