Abstract

This research aims to evaluate the implementation of Facility and Safety Management (MFK) at the Mutiara Sukma Mental Hospital (RSJ). This type of research is qualitative research with a descriptive approach. The informants for this research are MFK implementers, namely the K3 committee/installation, management, structural officials and visitors. Data collection was carried out using in-depth interviews. Examination of the trustworthiness of the data in this research includes credibility and dependability. Data analysis uses the thematic analysis model. The result of this research is that the evaluation of MFK implementation at the Mutiara Sukma Mental Hospital (RSJ) is less active in involving K3 installations in the planning process up to the evaluation. Implementation of Facilities and Safety Management (MFK) can run well if there is a clear priority scale and results that can be measured according to targets. It is necessary to improve the implementation and socialization of programs, such as the Hospital Disaster Plan, Contractor Safety Management, and fire protection systems that need to be identified and periodically evaluated for the security and safety of all those in the hospital environment. The four phases in the PDSA cycle have not run optimally. Increasing human resource capacity, managerial commitment, K3 structure and clarity of funding sources are still obstacles. Collaboration between K3 installations and policy makers is needed to reformulate improvements to the implementation of Facility and Safety Management (MFK).

Abstract

The existence of agricultural land is indirectly related to the environment. The existence of agricultural land in terms of environmental aspects can provide five types of benefits, namely preventing flooding, controlling water balance, preventing erosion, and reducing environmental pollution from household waste. This research aims to analyze environmental changes in the conversion of agricultural land to non-agricultural activities in Palembang City. This research uses quantitative methods, analytical quantitative research is conducted to accept or reject hypotheses that are described by significance values. The research also used qualitative methods by conducting measured interviews with 250 respondents. The research was conducted in May 2023 in three sub-districts in Palembang City, namely Kalidoni, Kertapati, and Gandus sub-districts. The environmental indicators used as a reference include water quality, air quality, soil conditions, traffic conditions, runoff water conditions, plant conditions, and animal conditions. The results showed that the condition of plant environmental quality in the Gandus and Kalidoni sub-districts is classified as poor, while the Kertapati sub-district is in the good category. While the condition of the environmental quality of animal indicators in the Kertapati and Kalidoni sub-districts is in the good enough category, but in the Gandus sub-district it is in the bad category. Dragonfly populations will be high if the habitat conditions are very suitable. This means that there are still streams or puddles that are still clean and food is available. This clean water is the place for dragonfly eggs and images for further development. So if the dragonfly population at a location is still high, it means that the water conditions at that location are still not polluted.

Abstract

Red calliandra is one of woody plants that has been extensively developed as biofuel. Tissue culture techniques are employed to produce a large and uniform quantity of seedlings in a relatively short period. Previous stages of in vitro initiation and multiplication of shoot from calliandra explants have shown promising results. The shoots that were multiplied by in vitro technique need to be induced for rooting process to produce plantlets. These plantlets are then prepared for the subsequent acclimatization process. This research was conducted in two stages; root induction of shoots using a modification of MS half-strength media (MS ½) supplemented with 1-4 mg/L 1-naphthaleneacetic acid (NAA), and acclimatization of the plantlets into soil media. The results shown that MS ½ medium and media supplemented with 1 mg/L NAA were suitable for root induction, particularly to induce the root length. Furthermore, MS ½ media supplemented with 1-2 mg/L NAA stimulates the increment of plantlet height and leaves numbers. Plantlets which were transferred into soil exhibit robust growth during 3-weeks of acclimatization process, up to 100% plantlets survived during this stage. These results underscore the potential of tissue culture techniques in providing large scale calliandra seedlings production for future biofuel development.

Abstract

Diabetes mellitus (DM) is a metabolic disorder that is accompanied  by an increased glucose in the blood or called hyperglycemia. Diabetes can be caused by problems with the pancreas not being able to produce insulin, insufficient insulin secretion, imperfect insulin action, or both. When blood glucose is left elevated for a long time, it can cause complications such as gangrene. Diabetic gangrene is one of the complications caused by tissue damage. Gangrene occurs due to neuropathy and vascular disorders, usually in the peripheral areas of the body. Bacteria found in diabetic wounds are bacteria that produce biofilms such as Staphylococcus aureus. Staphylococcus aureus can release exotoxins such as leukocidin. Leucosidine lyses PMNs and releases ROS which will then induce a cytokine response such as interleukin-6 which will increase CRP levels. hs-CRP is a high precision CRP measurement even at low concentrations.This study aims to determine the correlation between hs-CRP levels and the presence of Staphylococcus aureus in type II diabetes mellitus gangrene wounds. The research design used is observational analytical using a cross sectional approach and accidental sampling. There were 16 research respondents with increased hs-CRP levels in 15 respondents and 9 respondents with Staphylococcus aureus bacteria. Correlation test with a value of p = <0.05 (p=0.032) means that there is a correlation between hs-CRP and the presence of Staphylococcus aureus in type II diabetes mellitus gangrene wounds.

Abstract

Lempuk fish is a native Indonesian fish that is endemic in the Ranu Grati tectonic lake, Pasuruan Regency, East Java. This research aims to provide information in efforts to domesticate lempuk fish, especially on reproductive aspects related to the microscopic characteristics of gonads and reproductive type of Lempuk fish (Gobiopterus sp). This research uses the primary sexual characteristics method with gonadal histology. The variables observed included the male to female sex ratio, the histological structure of male and female gonads, and the reproductive type of lempuk fish. All data was analyzed descriptively, qualitatively and quantitatively by comparing with related literature. The samples taken in this research were 39 Lempuk Fish (Gobiopterus sp). The samples were then preserved in 10% formalin. The number of samples for histological analysis was 20 individuals, while for morphometric and meristic analysis there were 8 individuals. The results of the research show that morphologically the lempuk fish has a transparent body shape and there is a central line on the body with black or brown pigment and has a total length of around 2-3 cm. Lempuk fish have a type of reproduction that develops asynchronously (asynchronous) because the development of oocytes in the ovaries of female fish shows a variety of developmental stages, namely the initial growth stage (nuclear and perinuclear chromatin), cortical alveolar, vitellogenesis, and the mature stage. The sex ratio is predominantly female with a ratio of 0.64: 0.36. The histological structure of male and female gonads has histological differences that reflect different reproductive functions, where the ovaries play a role in egg cell production, while the testes are responsible for sperm formation. An imbalance in the sex ratio indicates the importance of carrying out domestication steps in order to prevent extinction or continuous population decline.

Abstract

Increasing cultivation activities and intensifying ponds has the potential to give rise to problems, namely increasing cases of disease in grouper fish, namely Zeylanicobdella, causing mass deaths of up to 100%. This study aims to analyze the histopathological picture of grouper skin infested with Zeylanicobdella arugamensis after administering papaya leaf juice with different soaking times and concentrations of papaya leaf juice. The method used was experimental Completely Randomized Design (CRD) with a factorial pattern consisting of two factors, namely factor A, different concentrations of papaya leaf juice consisting of 0% (A1), 0.1% (A2), 0.3% (A3) , and 0.5% (A4), as well as factor B for grouper rearing time consisting of the 0th minute (B1), 60th minute (B2), and 120th minute (B3) with five repetitions. The results of the study showed that the soaking time of papaya leaf juice in grouper fish had an effect on reducing the degree of Zeylanicobdella infestation, there were changes in the histopathological picture and water quality values before and after soaking. Treatments A2, A3, and A4 experienced a decrease in the degree of ectoparasite infestation at 60 and 120 minutes of immersion. The histopathological scoring values for treatments A2, A3, and A4 decreased at 60 and 120 minutes of maintenance. The best treatment combination was 0, 3% and soaking time at 120 minutes. In conclusion, giving papaya leaf juice with a soaking time of 120 minutes with a concentration of 0.3% can reduce the degree of infestation and the histopathological scoring value of Zeylanicobdella in grouper fish.
