Abstract

Cervical cancer is the second most common malignancy in Indonesia, and most of cases were already in advanced stage where radiotherapy is a tratement to given. Apoptosis is one of the markers for survival assessment of therapeutic response. In animal experiments MDM2 expression in various cell types to act as a survival factor by inhibiting the apoptotic function of p53 that is played by apoptosis can lead to malignant transformation and result in resistance to radiotherapy. Therefore, MDM2 is overexpressed due to alleged damage to p53 can also be used to assess the success of radiotherapy. This study aimed to assess the expression of MDM2 and p53 immunohistochemistry in cervical cancer and its relation to radiotherapy response. This study is a retrospective cross-sectional descriptive. The sample consisted of 23 cases of advanced cervical cancer were biopsied, 17 cases with complete response to radiation and 6 cases of partial radiation response. This study showed complete radiotherapy group MDM2 expression was found in 70.59% (12 cases) and p53 expression was found in 94.11% (16 cases), while the expression of MDM2, a partial response was found in 100% (6 cases), while the expression p53 66.67% (4 cases). MDM2 and p53 expression with SPSS 16 chi square test showed no association with response to radiotherapy in cervical cancer.

Abstract

Pasteurisasi merupakan metode untuk mempertahankan mutu susu segar. Namun tidak menutup kemungkinan mikroba patogen dan nonpatogen dapat tumbuh dan menurunkan mutu susu. Tujuan dari penelitian ini adalah melakukan analisis cemaran mikroba pada susu pasteurisasi produksi 7 pelaku usaha binaan UPH Peternakan Sapi Perah Pondok Ranggon, Jakarta Timur. Uji cemaran mikroba menggunakan uji Angka Lempeng Total (ALT), uji penegasan Eosin Methylene Blue Agar (EMBA), uji biokimia Indol, Merah metil, Voges Proskauer, dan Sitrat (IMVIC). Hasil penelitian uji ALT menunjukkan bahwa dari 20 sampel susu pasteurisasi tidak ditemukan angka lempeng total bakteri melebihi standar SNI No. 3951:2018 yaitu 1 x 104 CFU/mL.  Hasil uji penegasan menunjukkan 9 sampel susu pasteurisasi terdapat pertumbuhan bakteri diduga merupakan bakteri E. coli yang ditandai dengan warna ungu yaitu pada sampel 4, 8, 10, 13, 14, 15, 16, 18 dan 20. Namun hasil uji IMVIC menunjukkan bahwa bakteri E. coli hanya ditemukan pada 3 sampel yaitu sampel 13, 14 dan 16, yang ditandai dengan hasil uji indol (+), uji merah metil (+), uji vp (–) dan uji sitrat (–).Kata Kunci - Angka Lempeng Total, E. coli, IMVIC, Susu Pasteurisasi.

Abstract

Aloe vera is a plant that is easy to cultivate and has great potential to be processed into various economically valuable products, especially in the cosmetics sector, such as soap. However, in the partner environment, the use of aloe vera has not been maximized and there is a low entrepreneurial spirit among students. As a solution, this community service activity aims to provide education about entrepreneurship as well as training in processing aloe vera into soap. This activity was carried out in stages, starting with providing insight into bioentrepreneurship, followed by practical training in making aloe vera soap. To evaluate this activity, questionnaires were given to students before and after training. The results of the activity showed that there was an increase in knowledge regarding entrepreneurship and soap making skills. This activity had a positive impact on participants in creating and running an aloe vera soap business

Abstract

Most infectious diseases occur in the digestive tract caused by Salmonella typhimurium, while in the respiratory tract caused by Staphylococcus aureus. Continuous use of antibiotics as a treatment for bacterial diseases can result in resistance, therefore it needs to be balanced with the discovery of herbal medicines. Jatropha curcas is thought to have the ability to inhibit the growth of gram-positive and gram-negative bacteria. The purpose of this study was to obtain data and information on the antibacterial activity of Jatropha curcas leaf extract. This study used the paper disc diffusion method with 6 treatments and 3 repetitions. The treatments used were positive control (chloramphenicol), negative control (DMSO), and concentration of Jatropha curcas leaf extract of 10%; 20%; 40% and 80%. The results showed that Jatropha curcas leaf extract at concentrations of 10%, 20%, 40% and 80% had an effect on the growth of Salmonella typhimurium with the average inhibition zone obtained being 9.78; 9.19; 11.95; and 16.88 mm. At concentrations of 10%, 20%, 40% and 80%, it has an effect on the growth of Staphylococcus aureus with the average inhibition zone results obtained being 13.23; 14.83; 16.01; and 18.03 mm.Keywords – Jatropha Leaf Extract, Salmonella Typhimurium, Staphylococcus Aureus.

Abstract

Salmonella typhimurium bacterial infection remains one of the main causes of gastrointestinal diseases, and cases of resistance to conventional antibiotics are increasing. This encourages the search for alternative therapies based on natural ingredients, one of which is jengkol leaves (Pithecellobium jiringa) which are known to contain antibacterial compounds. This study is an in vitro experimental study aimed at evaluating the antibacterial effectiveness of ethyl acetate extract of jengkol leaves (Pithecellobium jiringa) against the growth of Salmonella typhimurium using the Kirby-Bauer disc diffusion method. Four extract concentrations (10%, 20%, 40%, and 80%) were tested against bacterial suspensions with chloramphenicol as a positive control, and DMSO as a negative control. Data were analyzed using one-way ANOVA and continued with Duncan's test to determine significant differences between treatments. The results showed a significant increase in the diameter of the inhibition zone as the extract concentration increased with the highest effectiveness at a concentration of 80% (mean inhibition zone 16.07 mm; strong category). Analysis shows that active compounds, such as flavonoids, tannins, and saponins, work through cell wall damage and bacterial membrane permeability. These findings indicate that jengkol leaf extract has potential as a natural antibacterial agent against gram-negative bacteria such as Salmonella typhimurium and is worthy of further development in phytopharmaceutical-based infection control efforts.
