Malaria is caused by the plasmodium parasite and still a threat to Indonesia. The main examination is staining of thick and thin smear preparations using Giemsa. Because giemsa is expensive, its waste is difficult to decompose, toxic and rare. Therefore, there is a need for new inventions to utilize the potential of natural components like mulberry fruit, which contains anthocyanins for coloring agents, to lessen the impact and risk of giemsa. The purpose of this study was to determine the effect of macerated ethanol extract of mulberry with a ratio of 1:3 (w/v) as an alternative to eosin in Giemsa on staining of thin blood smears of malaria, as well as knowing the best concentration in staining. This type of experimental research by observing the clarity of shape, color of parasites P.vivax, P.falcifarum, erythrocyte cells also compared with 3% giemsa as a control. This study consisted of 32 samples, 8 repetitions and 4 treatments namely P1 (3% Giemsa control), Giemsa modified mulberry eosin P2 (20%), P3 (30%), P4 (40%). The quality of the preparations was assessed based on the clarity and contrast of the colors. Kruskal-Wallis and Mann-Whitney data analysis techniques were used. The results showed that mulberry extract could be an alternative dye to replace eosin in the composition of giemsa on malaria thin smear preparations. The most effective concentration was 30% which could give the Plasmodium nuclei the same quality of staining as the control, while for the erythrocytes the staining quality was not the same as the control.

Rainfall is a climate variable that plays a crucial role in agricultural planning, water resource management, and hydrometeorological disaster mitigation. Therefore, a forecasting method capable of adequately describing the temporal patterns of rainfall data is required. This study aims to forecast monthly rainfall in Pesisir Selatan Regency using the Autoregressive Integrated Moving Average (ARIMA) method. The data used in this study are monthly rainfall data for the period 2015–2024. The analysis stages include missing data imputation, Box–Cox transformation, stationarity testing using the Augmented Dickey–Fuller (ADF) test, model identification through ACF and PACF plots, parameter estimation, and model evaluation based on the Akaike Information Criterion (AIC), residual diagnostic tests, and forecasting accuracy using Mean Absolute Percentage Error (MAPE). The results show that the ARIMA(0,1,1) model is the best model, as indicated by the lowest AIC value and residuals that satisfy the white noise assumption. The forecasting accuracy evaluation yields a MAPE value of 55.05%, indicating that the model’s ability to capture monthly rainfall variability is still limited. Rainfall forecasting for the period January to December 2025 produces relatively constant forecast values, reflecting the limitations of the ARIMA(0,1,1) model in representing seasonal variations. Therefore, this model is more suitable as a baseline approach for rainfall forecasting in Pesisir Selatan Regency. Future studies are recommended to apply models that incorporate seasonal components or external variables to improve forecasting accuracy.

In terms of analytic factors, it is important to define acceptable levels of common interferences, such as lipemia or hemolysis. For triglyceride, the laboratory technician must define whether samples with excess lipemia will be included in the study; this depends, in part, on whether the interferences affect the methods. In most laboratories, glass or plastic that is in direct contact associated with bio hazardous material is usually disposable. If not, it must be decontaminated according to appropriate protocols. Immediately rinsing glass or plastic supplies after use, followed by washing with a powder or liquid detergent designed for cleaning laboratory supplies and several distilled water rinses, may be insufficient. To ensure that all remaining fat from lipemic serum that attached to the tube wall has been removed, then the sterilization process is carried out so that a sterile tube is obtained. The purpose of this study is to determine the effect of test tube sterilization from serum lipemic against levels of triglyceride GPO-PAP (Glycerol-3-phosphate oxidase-p-aminophenazone) examination. This research method was a laboratory experiment. We used 8 times repetition with tubes used first are given liquid fat and cleaned by sterilization, washed with surfactant and washed with water only. By using statistical tests ANOVA obtained of this study showed results p>0.05 which is mean the treatment that used did not show a significant difference in the treatment of ordinary water-washed tubes with sterilized tubes and surfactant washed tubes. The conclusion of this study is cleaning of the test tube with the sterilization method is recommended because to avoiding the fear of remaining pollutants that can affect the results, It can also minimize the life of bacteria and viruses from the sample to be examined. However, if the sterilization method is difficult to do because of limited equipment and so on, the use of surfactants and the correct method of cleaning the tube is enough to remove impurities such as fat.

The high prevalence of Diabetes Melitus (DM) is a global problem that must be solved by health workers around the world. This study aims to determine the differences in the results of urine reduction examination using benedict method heated by spirtus flame and waterbath 100°C. This research method is a laboratory experiment. The results of this study indicated that the urine reduction examination by heating methylated flame and waterbath 100oC shows the same results from negative (-) until positive (+4). Examination of urine reduction by heating the methylated flame and waterbath 100oC did not affect the results. However, there are a difference in the process of urine reduction examination by heating flame which was need a longer time up to 3-5 minutes. Additionally, the solution in the tube could be exploded. It was also time consuming which could only carry out one by one sample. Meanwhile, the heating of urine by using 100oC waterbath is relatively faster, which only took 2 minutes. The urine was not also exploded when it was boiled and the heating process could perform 6-8 samples at the same time (depending on the tube rack). In conclusion, the heating method of urine by using waterbath was better than spirtus (methanol) flame since it could carry out large sample in one time and it was safer for the laboratory personnel.
