Abstract

Karbon aktif dari ampas teh telah disintesis dan telah diuji sebagai elektroda superkapasitor. Pembuatan karbon aktif berdasarkan variasi rasio massa karbon dan aktivator NaOH yaitu 1:4, 1;5 % b/b yang diberi kode AC-4 dan AC-5. Sintesis elektroda karbon aktif di awali dengan proses pra-karbonisasi dan dilanjutkan dengan proses aktivasi kimia. Sampel di karbonisasi pada suhu 800 oC dengan laju kenaikan 50C/menit dalam kondisi gas inert (N2). Karbon aktif ampas teh dikarakterisasi dengan SAA (Surface Area Assessment). Sifat elektrokimia dan kinerja elektroda karbon aktif yang disintesis diukur menggunakan metode voltametri siklik dalam larutan elektrolit H2SO4 1M. Elektroda karbon aktif menunjukkan kapasitansi spesifik tertinggi pada sampel AC-4 yaitu 67 F/g dengan scan rate 1 mV/s dan luas permukaan spesifik 473 m2/g. Mengingat sifat elekrokimia yang menarik tersebut, dan banyaknya ampas teh yang mudah ditemukan disekitar kita maka elektroda karbon aktif ini berpotensi untuk bahan pembuatan superkapasitor elektrokimia skala besar di masa depan.Activated carbon from tea waste has been synthesized and has been tested as a supercapacitor electrode. Making activated carbon based on variations in the ratio of carbon mass and activator NaOH that is 1: 4, 1; 5%wt coded AC-4 and AC-5. Synthesis of activated carbon electrodes begins with the pre-carbonization process and is followed by a chemical activation process. Samples are carbonized at 800 oC with a rate of increase of 50C / min under inert gas (N2) conditions. Activated carbon of tea waste is characterized by SAA (Surface Area Assessment). The electrochemical properties and performance of the activated carbon electrode were measured using the cyclic voltammetry method in a H2SO41 M electrolyte solution. The activated carbon electrode showed the highspecific capacitance in the AC-4 sample of 67 F / g with a scan rate of 1 mV / s and surface area Specifically 473 m2 / g. Considering these interesting electrochemical properties, and the abundance of tea dregs that are easily found around us, this activated carbon electrode has the potential to be a material for making large-scale electrochemical supercapacitors in the future.Keywords:Limbah ampas teh, Aktivator, Kapasitansi spesifik, NaOH, Supekapasitor

Abstract

Science has an important role in improving the quality of human life and has significant positive effects on the development of children’s personality and potential. However, many people believe that science is a challenging field of study. Therefore, it is important to introduce science to children at a young age in an entertaining way. This community service activity aims to introduce science to early childhood and increase children's abilities and interest in science. The target of this activity is children from middle-class to lower-class families that live in the area of the Rumah Pintar Mingguan (RPM) Kreatif Ampang. Five RPM volunteers and 31 children participated in this activity. This PKM activity was carried out through a simple science mini-practicum, by utilizing simple and inexpesive materials and tools that can be found easily in the surrounding environment. The main ingredients were baking soda and vinegar (acetic acid). The method used in this activity were a case study and hands-on practice. Two topics that are carried out on this practicum, namely the phenomenon of an erupting Merapi volcano and inflating a balloon without being blown up. This practice has the effect of increasing children's interest in and motivation for science, which is directly correlated with their increased comprehension of the concepts being demonstrated. Additionally, RPM decided to make this science practicum activity as a regular agenda item for the RPM community.

Abstract

Medicinal plants particularly grown by family in their own garden namely “Tanaman Obat Keluarga” (TOGA) can be used to prevent disease, promote and improve health condition and cure disease. In addition, TOGA also contributes in increasing family prosperity since medicinal plants have significant economic value. Female students known as “santriwati” who stay in Islamic boarding schools are vulnerable to diseases due to lack of hygiene and high residential density. Skin diseases, diarrhea, flu and fever are some of those diseases that students prone to be infected. Considering their conditions, which stay apart from their families, hence, independence and sufficient knowledge regarding health aspects are very necessary. This community service activity aimed to educate female students regarding the use of various types of medicinal plants (TOGA) to maintain health and treat various diseases. This socialization activity was carried out in the Islamic boarding school of the Sahabat Cendekia - Middle School/Senior High School, District of Central Pariaman, Pariaman City with 87 targeted female students. Santriwari are informed about the material related to the types of TOGA that can be planted in Islamic boarding school environments, the benefits of TOGA and how to process TOGA so that it can be used as an agent for disease prevention, health maintenance and illness treatment

Abstract

Scurrula ferruginea (Benalu) is a hemiparasitic plant with potential as a raw material for traditional medicine due to its high flavonoid content. The concentration of flavonoids is substantially determined by the specific drying technique applied. Studies investigating the use of the stir-frying method remain limited, and there is no standardized protocol has yet been established to recommend an appropriate method for preserving the total flavonoid content in S. ferruginea leaves. This study aims to compare the total flavonoid content (TFC) in ethanol extracts of Benalu leaves on the Jengkol dried using three different methods: air-drying, oven-drying, and stir-frying drying. All samples were subsequently powdered and subjected to maceration using ethanol solvent, followed by analysis of their total flavonoid content using spectrophotometry UV-Vis at maximum wavelength at 431 nm. Statistical analysis of one-way ANOVA showed that different drying methods generated significant effects on TFC level of Benalu leaves extracts with significance value = 0.001 (p-value <= 0.05). The results indicated that air-drying yielded the highest flavonoid content with 7.37 ppm, followed by stir-frying (4.93 ppm) and oven-drying (2.88 ppm). These findings highlight the critical importance of selecting an appropriate drying method to preserve flavonoid levels, thereby enhancing the pharmacological efficacy and quality of herbal products derived from S. ferruginea leaves.
