Abstract

An UMKM (micro, small and medium scale business) in the city of Pangkalpinang, Province of Kep. Bangka Belitung, with the trademark "kebajig Lure", produces metal jigs or artificial/fake bait made of metal. One of the problems in the process of making metal jigs at UMKM is bending the wire on the metal jig, because the bending process uses loop pliers which causes the wire to be made to be non-uniform (where 10 wires, below 50% of the wire deviates from tolerance) so that the stray wire must be repaired first before the metal jig molding process. In addition, the bending time of 1 piece of wire takes about 80 seconds. This study aims to accelerate the metal jig bending process and to obtain a uniform wire with a deviation of ± 0.2 mm. After conducting the survey and initial analysis, the making of tools for bending wire is the solution. In the process of making these tools, the VDI 2222 design method is used, starting from planning, conceptualizing, designing, and finally finishing. Then carried out the process of making tools and testing wire bending. The results of the experiments conducted showed that the uniformity level of the metal jig wire was around 70% and the time required in the 1-wire bending process was ± 10 seconds, with an efficiency of ± 70 seconds from the previous process. And in the metal jig molding process, the wire repaired before the molding process is only about 30%.

Abstract

Ethanol extract of bay leaves is known to have pharmacological activities such as anti-inflammatory, antihypertensive, and antidiabetic. However, its stability and solubility are still challenges. Therefore, a microencapsulation-based delivery system with floating characteristics that can last longer in the stomach was developed. This study aims to evaluate floating microencapsulation preparations containing ethanol extract of bay leaves (Syzygium polyanthum) as an effort to increase the effectiveness and bioavailability of active substances orally. The results showed that microencapsulation had a total floating of more than 4 hours with a water content of 0.47% -2.14%. Stability tests showed no significant changes in physical and chemical characteristics after cycling tests.

Abstract

The wound healing process in individuals with diabetes mellitus is generally slower due to disruption of the inflammatory, proliferation, and regeneration mechanisms. Diabetics experience chronic metabolic disorders that impact immune cell function, blood circulation, and the regenerative capacity of fibroblasts and keratinocytes. Consequently, the wound healing process in diabetic patients is often more complex and takes longer. One approach to accelerating the wound healing process in this condition is the use of natural ingredients with anti-inflammatory, antimicrobial, and regenerative properties. One potential plant in this regard is the bandotan leaf (Ageratum conyzoides), which is known to contain active compounds such as flavonoids, alkaloids, and tannins that play a role in the wound healing process. This study was conducted to assess the effectiveness of bandotan leaf extract in accelerating wound healing in an animal model of diabetes mellitus. A total of 30 male white rats (Rattus norvegicus) that had been induced to become diabetic with streptozotocin were divided into six groups of five rats each. The groups included: a normal control group (healthy mice without diabetes), a negative control group (diabetic mice without treatment), a positive control group (given Metcovazin ointment as a standard), and three treatment groups that received topical application of bandotan leaf extract at graded concentrations of 10%, 15%, and 20%. A circular wound with a diameter of approximately 6 mm was made aseptically using a punch biopsy tool on the back of each mouse after being given ketamine anesthesia. Treatment was given daily for twelve consecutive days. The main parameters observed included daily measurements of the wound area to determine the rate of wound contraction.

Abstract

This study aimed to evaluate the nephroprotective effect of mango peel extract (Mangifera indica L.) on the kidney function of male white rats (Rattus norvegicus) induced by rifampicin. Rifampicin is a first-line antibiotic used to treat tuberculosis, but its repeated use can cause side effects, including nephrotoxicity. This nephrotoxic effect can damage kidney function and disrupt the body's balance. Therefore, the search for agents that can protect the kidneys from damage caused by rifampicin is important. One potential natural nephroprotective agent is mango peel extract, which is known to contain bioactive compounds with antioxidant and anti-inflammatory activities, such as flavonoids, tannins, and saponins. This study was conducted experimentally with five treatment groups. The normal control group was given distilled water, the negative control group was given rifampicin, and three treatment groups were given mango peel extract at doses of 100, 200, and 400 mg/kgBW. The parameters observed included serum creatinine levels in rats before and after treatment, as well as histopathological features of kidney tissue to assess the presence of structural damage to the kidneys. The results showed that rifampicin administration increased serum creatinine levels, indicating impaired kidney function, and caused structural damage to kidney tissue. However, administration of arumanis mango peel extract, especially at a dose of 400 mg/kgBW, significantly reduced serum creatinine levels, approaching normal control values, and improved kidney histological structure. The damage score in kidney tissue in the group given arumanis mango extract also showed significant improvement compared to the negative control group. This nephroprotective effect is thought to be related to the content of bioactive compounds in arumanis mango extract, which have antioxidant and anti-inflammatory activities, which can reduce oxidative stress and inflammation in the kidneys.

Abstract

Gentamicin is an antibiotic widely used in medicine to treat serious bacterial infections, particularly urinary tract, respiratory tract, skin, and soft tissue infections. This drug belongs to the aminoglycoside class, which works by inhibiting bacterial protein synthesis, preventing bacterial survival. Despite its high efficacy, gentamicin has significant side effects, particularly on the kidneys. Long-term or high-dose use of gentamicin can cause nephrotoxicity, which is damage to kidney tissue characterized by decreased filtration function, impaired glomerular and tubular structure, and increased blood creatinine and urea levels. This occurs because gentamicin tends to accumulate in the proximal tubules of the kidneys, triggering oxidative stress and inflammation. To reduce the toxic effects of gentamicin on the kidneys, nephroprotective agents are needed. One potential natural ingredient is mangosteen rind extract (Garcinia mangostana). Mangosteen rind is known to contain active compounds such as xanthones, which have antioxidant, anti-inflammatory, and antimicrobial properties. This compound is capable of neutralizing free radicals and suppressing the inflammatory response, which is one of the causes of kidney tissue damage. This study aimed to determine the effect of mangosteen peel extract on the histological appearance of the kidneys of rats treated with gentamicin. Histological analysis was performed to observe changes in kidney structure, such as tubular cell degeneration, necrosis, or inflammatory cell infiltration. It is estimated that administering mangosteen peel extract can minimize or prevent kidney tissue damage, making it an alternative complementary therapy to gentamicin. This research also marks the first step in the development of safe and effective herbal-based phytopharmaceuticals to support kidney health.

Abstract

Fires caused by household negligence remain a major domestic hazard, particularly in densely populated residential areas. This study aimed to analyze household negligence factors associated with fire risk. A quantitative analytic study with a cross-sectional approach was conducted on 70 households, examining individual characteristics (age, sex, education, and occupancy density) and negligence behaviors (electrical installation, smoking behavior, gas-stove use, candle/mosquito-coil use, and storage of flammable materials) in relation to fire risk (high/low). Bivariate analysis used Fisher's exact test, while multivariate analysis used Firth's bias-reduced logistic regression owing to the limited number of high-risk events and quasi-complete separation. Bivariate analysis showed that age (p=0.041), smoking behavior (p=0.001), and candle/mosquito-coil use (p=0.011) were significantly associated with fire risk. Multivariate analysis identified smoking behavior as the most dominant factor (aOR=24.03; 95%CI=1.29–449.15; p=0.033). Smoking behavior and unsafe use of candles or mosquito coils were the most influential negligence factors associated with household fire risk. Given the very small number of high-risk events, these findings should be regarded as preliminary and require confirmation using larger field-based samples.
