Problem solving is one of the skills that students must have after learning mathematics. Learning mathematics that develops problem solving skills gets less attention from the teacher so that students lack problem solving skills. Learning that combines knowledge, skills and creative thinking, emphasizing student experience and active participation in problem solving. The purpose of this study was to conduct a literature review on improving mathematical problem solving skills and learning outcomes using the PBL learning model. This research is qualitative in nature and the method used in this research is SLR (Systematic Literature Review). Data collection was carried out by reviewing all articles and journals related to the application of problem-based learning models to improve problem-solving abilities and students' mathematics learning outcomes in elementary schools. After the data is collected, the data found is verified and compared. Data analysis techniques were carried out qualitatively by quoting relevant opinions. Based on the results of the literature review, it can be concluded that the problem-solving abilities and mathematics learning outcomes of elementary school children can be improved through the problem-based learning model.

The Somber Small Industry Center's Regional Technical Implementation Unit (UPTD) is one of Balikpapan's tofu and tempeh industrial sectors. Based on observations performed throughout the implementation of tofu production at Mr. Rahim's production house, it is known that the production capacity of tofu varies every month due to the shortage of a tofu production plan, resulting in Mr. Rahim's production house losing 816 kg worth Rp. 20.400.000 in 2022. The purpose of this study was to plan and offer recommendations for tofu manufacturing capacity and time that are suitable for Mr. Rahim's production house. Forecasting moving averages, weight moving averages, exponential smoothing, and linear trend line models are applied in the tofu production planning approach. The research results in capacity planning and production time of tofu using the forecasting method of moving average over 3 periods and 6 periods, respectively, 6081 kg/month and 6025 kg/month; weight moving average over 3 periods and 2 periods, respectively, 5792 kg/month and 5504 kg/month; exponential smoothing method with alpha 0.80, 0.90, and 0.95, respectively, 5258 kg/month, 5080 kg/month, and 4990 kg/month; and the linear trend line model method of 6317 kg/month. The conclusion of this study using the best feasible forecasting method is the weight moving average with two weighting periods, with a total required capacity of tofu production time of 1671.0144 hours/year and a total capacity of available tofu production time of 1874.6112 hours/year due to the difference in actual demand with a forecast of 732 kg, which does not exceed the value of lost sales in 2022.

Background: Condylomata acuminata (CA) is a prevalent sexually transmitted infection (STI). Research into the risk factors and characteristics associated with CA is crucial for developing effective prevention strategies. This study aimed to determine the prevalence and characteristics of CA patients at Prof. Dr. I.G.N.G. Ngoerah General Hospital in Denpasar, Bali, Indonesia. Methods: A retrospective cross-sectional study was conducted using medical records of CA patients attending the STI and Dermatology Clinic at Prof. Dr. I.G.N.G. Ngoerah General Hospital, Denpasar, from January 2021 to December 2023. Data collected included patient visit status, age, gender, occupation, education, concomitant STIs, sexual orientation, marital status, and use of protective measures. Data were processed descriptively. Results: Of 284 CA patients, 69.7% were male and 30.3% were female. The mean age was 28.99 ± 11.38 years. Married individuals constituted 41.5% of cases. Private employees were the predominant occupation (34.2%). Fifty percent of patients had no concomitant STIs, while HIV was present in 37.7% of the total sample (75.4% of those with any concomitant STI). A significant proportion (49%) reported not using protective measures during sexual intercourse. Conclusion: The prevalence of CA at Prof. Dr. I.G.N.G. Ngoerah General Hospital, Denpasar, was 40 per 1000 visits during the study period. CA was predominantly observed in adult males who were married, heterosexual, had completed high school, worked as private employees, and did not use protective measures during sexual intercourse. These findings underscore the need for targeted public health interventions.

Background: The inexorable rise of antimicrobial resistance (AMR) in Neisseria gonorrhoeae represents a formidable threat to global public health, jeopardizing the efficacy of last-line treatments for gonococcal urethritis (GO). Southeast Asia is a recognized epicenter for the emergence and dissemination of AMR, yet granular surveillance data from many high-risk localities remain critically sparse. This study aimed to provide a comprehensive characterization of the clinical epidemiology, frontline management practices, and patient outcomes of male urethritis at a tertiary referral center in Bali, Indonesia—a major international crossroads for tourism and migration. Methods: A retrospective, cross-sectional analysis was conducted on the medical records of male patients diagnosed with urethritis at the Dermatology and Venereology Polyclinic of Ngoerah Hospital between January 1st, 2021, and December 31st, 2024. A rigorous screening process of 215 initial records was undertaken to identify eligible cases. Data on sociodemographics, behavioral risk factors, clinical presentation, syndromic diagnosis, prescribed pharmacotherapy, and follow-up adherence were systematically extracted and analyzed using descriptive and comparative statistics. Results: From the initial cohort, 58 male patients met the final inclusion criteria. The cohort was predominantly diagnosed with GO (n=39, 67.2%) over non-gonococcal urethritis (NGO) (n=19, 32.8%). Patients were primarily of productive age (25–44 years, 58.6%) and reported high-risk behaviors, including multiple sexual partners (65.5%). A critical deviation from international treatment guidelines was identified: 97.4% (38/39) of GO patients received oral cefixime 400 mg monotherapy, a regimen no longer recommended for first-line use due to AMR concerns. Furthermore, a profound fracture in the care cascade was evident, with an overall loss-to-follow-up rate of 58.6% (34/58). This failure was most pronounced in the GO cohort, where 76.9% (30/39) of patients did not return for scheduled follow-up, a rate significantly higher than the 21.1% (4/19) observed in the NGO cohort (p<0.001). Conclusion: The clinical management of gonorrhoea at this major Indonesian referral center is defined by two systemic failures: the routine prescription of a suboptimal antimicrobial monotherapy and a near-total collapse of patient follow-up. This combination, situated in a high-transience international hub, creates an unmonitored, high-risk environment for the selection, amplification, and global dissemination of antimicrobial-resistant N. gonorrhoeae. These findings signal an urgent imperative to align local therapeutic protocols with evidence-based global standards and to implement robust, innovative strategies to ensure patient retention and verify the cure.
