Abstract

Soursop leaf (Annonamuricata L) is a fruit plant originating from the Caribbean, Central America, and South America. In soursop leaves, there are flavonoid compounds, namely phenol compounds with antioxidant, antibacterial, antiviral, anti-inflammatory, anti-allergic, and anticancer activities. The capture of free radicals causes this compound's antioxidant effect via the hydrogen atom donor from the flavonoid hydroxyl group. Some diseases such as atherosclerosis, cancer, diabetes, parkinsonism, Alzheimer's, and decreased immunity have been affected by free radicals in the human body. Flavonoids are of concern because of their medicinal role in the prevention of cancer and cardiovascular disease. One obstacle in the use of soursop leaf extract is the inefficiency of the solvent used so far. This research uses ethanol solvent because ethanol solvent can extract soursop leaves with flavonoid levels 1.36% greater than n-hexane solvents, flavonoid content is 0.66%, and 2propanol solvent is chosen because its polarity is lower than ethanol, so it is expected to extract flavonoid levels. More optimal than ethanol. This study aims to determine the optimization of maceration time and type of solvent on the levels of flavonoids in the soursop leaf extract. This study was designed with a 2 level design factorial method, and two variables changed, namely maceration time (48, 72, 96) hours, ethanol, and 2propanol fractionation solvent types. Fixed variables used were drying time 30 minutes temperature 50oC, sample weight of soursop leaf 10 grams, extraction solvent volume 200 ml, extraction temperature 28oC (room temperature), the method used spectrophotometer. These static and changing variables have a positive effect that can increase phenol levels, and the most influential variables are the type of solvent and extraction time. The best conditions in the cytotoxic extraction process are ethanol solvent and maceration extraction time of 72 hours.

Abstract

Mangliawan Village is a village in the red zone vulnerable to the spread of the Covid-19 virus. In Mangliawan village, there is the Global Tarbiyyatul Arifin Islamic boarding school, which is one of the non-formal Islamic education institutions for students. The Religion Ministry has urged one of them with a circular regarding the safety of Covid-19 to break the chain of Covid-19 transmission in the boarding school environment. The Global Tarbiyyatul Arifin Islamic boarding school needs to carry out health protocols, by washing hands with soap under running water. Also, it is necessary to use antiseptic fluids in outdoor conditions during a pandemic. Based on these problems, the community service team provided training on making hand soap and hand sanitizers to be more independent in overcoming the spread of Covid-19 in the pesantren environment. Besides training, they were also given counseling on how to avoid the spread of Covid-19 and how to maintain immunity to fend off the coronavirus. As a result of this activity, the pesantren and the surrounding community's residents understand more and protect themselves by making hand soap and hand sanitizer independently quickly.Keywords: Covid 19, Hand Soap, Hand Sanitizer, Immune, Islamic Boarding SchoolABSTRAKDesa Mangliawan adalah sebuah desa yang termasuk zona merah rentan tersebar virus Covid-19. Di desa Mangliawan terdapat pesantren Global Tarbiyyatul Arifin yaitu salah satu lembaga pendidikan Islam non formal bagi para santri. Kementrian Agama telah menghimbau salah satunya dengan surat edaran terkait amannya Covid-19, untuk memutuskan rantai penularan Covid-19 di lingkungan pondok pesantren. Sehingga pesantren Global Tarbiyyatul Arifin perlu menjalankan protokol kesehatan salah satunya dengan mencuci tangan dengan sabun di bawah air yang mengalir. Selain itu perlu juga untuk penggunaan cairan antiseptik pada kondisi di luar rumah di masa pandemi. Berdasarkan permasalahan tersebut, maka tim pengabdian masyarakat memberikan pelatihan cara membuat hand soap dan hand sanitizer supaya lebih mandiri dalam menanggulangi penyebaran Covid-19 di lingkungan pesantren. Selain diberikan pelatihan, mereka juga diberikan penyuluhan tentang cara menghindari penyebaran Covid-19 dan cara menjaga imun untuk menangkis virus corona. Hasil dari kegiatan ini, para penghuni pesantren dan masyarakat di sekitarnya semakin paham dan lebih bisa menjaga diri dengan membuat hand soap dan hand sanitizer secara mandiri dengan mudah.Keywords: Covid 19, Hand Soap, Hand Sanitizer, Imun, Pesantren

Abstract

This study aims to determine percent yield and chemical composition of volatile oil from citrus peel that extracted by using Microwave Hydrodiffusion and Gravity method. Chemical composition was analyzed using Gas-Chromatography method. Based on gas chromatography analysis (GC) obtained 9 peaks with different retention time according to the type of compound that was analyzed. The highest peak comes with retention time of 8.440 with wide area 22623980 (97,78%) and height 7241224 (96,70%). Height is the distance from the base line to the maximum peak usually in mm, while the area is the area under the peak, and indicates the abundance of a component. Retention time is the time interval required by the solute (component) to get out of the column and reach the detector.

Abstract

One source of essential oil that has long been popular is a citrus fruit (Citrus aurantium). Results waste citrus peel around 500,000 tonnes per year. So the prospects for the utilization of waste orange peel are big enough to extract the essential oil. However, conventional extraction methods have drawbacks in terms of product quality, so to find solutions to these shortcomings, it is necessary to use the extraction method by Microwave Hydrodiffusion and Gravity (MHG). This method combines the use of microwave heating and physical phenomena (hydrodiffusi and earth gravity) at atmospheric pressure, without addition of organic solvents or water. In this study used fresh orange peel material 400 and 500 grams, two variable microwave power of 100 and 300 Watt and the extraction time for 15, 30, 45 and 60 minutes. To know the processing time and the microwave power effective method of MHG, oil composition was analyzed by GCMS to determine the amount of the fraction of oxygenated compounds. The larger of installed microwave power, the higher of operating temperature, so the %yield increases in a shorter time. From the comparison of energy consumed, the MHG method is give 30% more energy efficient than the Microwave Hydrodistillation (MHD) method. The use of microwaves does not change the physical properties of oil. The oil produced from the MHG method has a good quality because it has specific gravity and refractive index values that meet the EOA quality standard and has a greater oxygenated compounds content than the MHD method
