Abstract

Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia that occurs due to abnormalities in insulin secretion, insulin action or both. DM sufferers are increasing from year to year, accompanied by increasing costs of therapy, therefore, as an alternative to controlling blood glucose levels, use natural ingredients such as cocoa leaves. The aim of this research was to determine the effectiveness of ethanol extract of cocoa leaves (Theobroma cacao L.) in reducing blood glucose levels in mice that had been induced by Aloxan. The research method used was experimental research. The research stages were sample collection, sample identification, making simpilicia, examining the characteristics of simpilicia, making extracts using maceration using 96% ethanol solvent, and testing the antidiabetic effect of EEDC in mice induced by alloxan at a dose of 175 mg/kg. bb intraperitoneally. Diabetic mice were divided into 5 groups, each group consisting of 5 mice that were given the test material 50 mg/KgBB of ethanol extract of brown leaves; 100 mg/KgBB; and 200 mg/KgBB, Metformin 65 mg/KgBB, and CMC 0.5%. Next, blood glucose levels were measured on days 3, 6, 9, 12, and 15, the percentage reduction in blood glucose levels was calculated, then the data was analyzed using the One-Way ANOVA method and Duncan's test, to see real differences between treatments. The research results showed that simplicia, the ethanol extract of brown leaves contains flavonoids, alkaloids, tannins, steroids/triterpenoids, saponins and glycosides. Cocoa leaf ethanol extract has effectiveness in lowering glucose levels, at the 5th and 6th hours it shows good effectiveness at a dose of 200 mg/KgBW of (72.16 ± 0.1.51)% and (82.80 ± 0.73 )%, not significantly different from metfromin 65 mg/KgBB of (74.45 ± 1.51)% and (83.29 ± 1.01).

Abstract

Di pasaran banyak beredar sabun antiseptik mengandung antibakteri sintetis, namun sering menimbulkan efek samping, maka perlu dibuat sabun mengandung antiseptik alami contohnya buah rimbang yang mengandung senyawa metabolit sekunder dan mempunyai aktivitas antibakteri. Tujuan dari penelitian ini adalah untuk membuat formulasi sabun padat transparan sebagai antiseptik dari ekstrak etanol buah rimbang. Formulasi sabun padat transparan tanpa bahan uji (Blanko) dan ekstrak etanol buah rimbang konsentrasi 1,5%, 2% dan 2,5% dilakukan uji evaluasi mutu pada sediaan. Kemudian dilakukan uji efektivitas pada ekstrak etanol buah rimbang dan sediaan sabun padat transparan. Hasil uji skrining fitokimia pada simplisia dan ekstrak etanol buah rimbang memenuhi syarat mutu fisik pada senyawa metabolit sekunder. Hasil aktivitas antibakteri konsentrasi 2,5% diameter hambatan terhadap Staphylococcus aureus 19,47 ± 0,85 menunjukkan diameter hambatan sangat kuat. Angka lempeng total terhadap spesimen cuci tangan sukarelawan, EEBR 1,5% telah terjadi pengurangan koloni bakteri sebesar 73,32%, EEBR 2,5% diperoleh pengurangan bakteri paling besar yaitu 98,51%, hampir sama dengan sabun padat yang beredar di pasaran yaitu 98,75%. Dari penelitian ini dapat disimpulkan bahwa sediaan sabun padat transparan ekstrak etanol buah rimbang sebagai antiseptik memenuhi syarat dalam pembuatan sabun mandi.

Abstract

Poor oral health is often caused by inadequate oral hygiene, leading to conditions such as bad breath and periodontal disease. Bingkat Village, located in Pegajahan Subdistrict, Serdang Bedagai Regency, is predominantly inhabited by farmers, with many housewives lacking productive activities to support their families’ income. This community service program aimed to provide training for PKK (Family Welfare Movement) women on producing mouthwash using natural ingredients, particularly torch ginger extract, which is known to contain antibacterial compounds. The implementation methods included educational sessions, hands-on training, and assistance with product formulation, packaging, and marketing. The results indicated an improvement in participants’ understanding and skills in producing herbal mouthwash, as well as the emergence of economic opportunities through the development of local products.

Abstract

The service system for every laundry in every area is currently still done manually, this is considered less efficient because the waiters are often confused when looking for clothes that a customer wants to pick up. Then waiters sometimes forget to give information to customers to pick up clothes that have been washed. This becomes a problem where customers have to go back and forth to ask whether their clothes have been washed or not. Smart laundry is a form of implementation whose main objective is to help customers find out which clothes are ready to be picked up and can help waiters find out where the customer's clothes are. RFID tags for customers who are registered as members of the laundry service are used as a tool to store customer data when the customer brings clothes to be washed and to find out where the customer's clothes have been washed when the customer picks up the clothes. This research also uses the QoS (Quality of Service) method to measure the delay parameters produced in the network used. The results of testing that were carried out 35 times in this research resulted in a delay of 0.956458 seconds. From the test results, the maximum reading distance between the RFID tag and the RFID reader is 3 cm. From the results of 10 trials, the percentage of system success in sending notifications in the form of clothes that have been completed and ready to be picked up to customers is 80% and system failure in sending notifications is 20%.
