This study aims to determine the effects of temperature and Aloe vera concentration on the physicochemical and organoleptic properties of mixed mulberry (Morus alba) jam. Jam is a semi-solid fruit and sugar-based product that requires a thickening agent to achieve optimal texture. Aloe vera was selected as a natural thickening alternative due to its polysaccharide content, such as acemannan and glucomannan, which can form gels, replacing expensive and import-dependent commercial pectin. The research employed a quantitative experimental method with a Completely Randomized Design (CRD), involving four treatment combinations of Aloe vera concentration (75 g and 100 g) and cooking temperature (70°C and 85°C). The parameters tested included physicochemical properties such as viscosity, fiber content, and vitamin C levels, along with organoleptic evaluations involving 25 panelists to assess viscosity and taste. Data were analyzed using analysis of variance (ANOVA) and an effectiveness test to identify the best treatment. The results showed that the combination of 100 g Aloe vera concentration and a cooking temperature of 85°C produced the best-quality jam, characterized by optimal viscosity, high fiber content, preserved vitamin C levels, and high panelist preference for viscosity and taste. This conclusion highlights the potential of Aloe vera as a cost-effective and value-added natural thickening agent for the food industry.

The aim of the study was to determine the frequency of occurrence of patients who were operated on for acute adhesive bowel obstruction and had a history of only appendectomy, and to identify risk factors for the development of acute adhesive bowel obstruction based on this frequently encountered surgical condition. A retrospective study was conducted on 84 patients, all of whom were operated on for acute adhesive bowel obstruction, had a history of appendectomy only, and were over 18 years old. The study period was from 2020 to 2024. The following statistical data were collected: gender, age at the time of surgery for acute adhesive bowel obstruction, method of surgical access during appendectomy, method of processing the stump of the vermiform appendix, duration of hospitalization, histological features of acute appendicitis, complications of acute appendicitis, time from appendectomy to surgery for acute adhesive bowel obstruction, data on the prevalence of the adhesive process using the peritoneal adhesion index, and the presence of purulent complications of wounds after appendectomy. Signs of early acute adhesive intestinal obstruction were observed in 21 patients, 8 of whom were resolved conservatively. The conservative treatment consisted of infusion therapy, intestinal stimulation by intramuscular injection of neostigmine methylsulfate, and cleansing enemas with a hypertonic solution. The study showed that the likelihood of developing adhesive disease of the abdominal cavity is more frequent after complicated forms of acute appendicitis due to late diagnosis, general purulent peritonitis, and open surgical approaches to appendectomy.
