ANALYSIS OF IMPLEMENTATION OF MALARIA CONTROL POLICY AT SIDODADI HEALTH CENTER ASAHAN DISTRICT

Abstract Malaria is a serious and potentially fatal public health problem. Malaria elimination efforts are carried out in Indonesia to create a society that is free from malaria transmission in 2030. This study aims to analyze the implementation of malaria control policies at the Sidodadi Community Health Center, Asahan District. This study used a qualitative approach involving the head of the Community Health Center and the malaria program manager as respondents. The results showed that the management of malaria sufferers was quite good, but there were still obstacles in the availability of malaria drugs at the Sidodadi Health Center. Prevention and management of risk factors for malaria are also not optimal due to the lack of facilities and infrastructure for health workers. Epidemiological surveillance and epidemic control still need to be improved according to the standards of the Ministry of Health. Communication, information, and education in malaria prevention is quite good. The improvement of human resources at the Sidodadi Health Center has also been carried out well, but the Asahan District Health Office needs to continue to prioritize the malaria elimination program and continue to improve education for field workers.

Application of Rice Field Snails (Pila ampullacea) Extract as an Alternative Substitute for Protein Sources in Export-Quality Catfish Feed (Clarias sp.)

The freshwater fishery commodity that ranks at the top in total production in Indonesia, and its high domestic consumption, is catfish (Clarias sp.). One of the efforts to provide alternative feeds is by using rice field snails (Pila ampullacea) due to their high protein content. This study aims to determine the content of P. ampullacea feed and its application as an alternative protein source in export-quality Clarias sp. The feed was prepared by combining P.ampullacea flour, rice bran, and corn flour in a ratio of 3:1:1. Analysis of water content was conducted using the weight reduction method, ash content using the ashing method, protein content using the Kjeldahl method, and fat content using the soxhletation method. The analysis results showed that P. ampullacea had water content of 7.97%, ash content of 10.36%, protein content of 50.17%, and fat content of 4.16%. Meanwhile, the P.ampullacea feed had water content of 10.49%, ash content of 8.26%, protein content of 48.74%, and fat content of 3.6%. The results indicated that the application of P.ampullacea to Clarias sp. led to an increase in protein and fat content every week, the levels found in the commercial feed used

Cadmium (Cd) Resistance of Isolate Bacteria from Poboya Gold Mining in Palu, Central Sulawesi

The mining industry in Indonesia is growing rapidly, giving an environmental impact from the waste produced because it contains dangerous heavy metals, one of which is cadmium metal (Cd). The purpose to know the ability of cadmium resistance in bacterial isolates. Bacterial isolates were obtained from soil samples from the Poboya Gold Mine field, Palu. Bacterial isolation and selection were carried out by the plate count method, resistance testing using nutrient broth media containing heavy metals Cd, analysis of Cd concentrations using atomic absorption spectrophotometers. From the results of the study, four types of Cd resistant isolates were obtained based on macroscopic and microscopic characterization results, namely isolates EK1, EK2, EK3 and EK4. The two best isolates of Cd resistance, EK2 and EK4 isolates were tested on media containing 20 ppm Cd, showing that both of these isolates were able to significantly reduce Cd concentrations in the supernatant and pellets

Sintesis Nanopartikel Perak Menggunakan Ekstrak Daun Salam (Syzygium polyanthum) Sebagai Bioreduktor Dan Uji Aktivitasnya Sebagai Antioksidan

Silver nanoparticles have been synthesized by the reduction method using salam leaf extract (Syzygium polyanthum) as a reducing agent. The silver nanoparticles produced were then tested for their activity as antioxidants. The formation of silver nanoparticles was carried out by adding the leaf extract into the solution of AgNO3 and homogenized using a magnetic stirrer. A UV-Vis spectrophotometer was used to confirm the formation of silver nanoparticles. Particle Size Analyzer (PSA), Scanning Electron Microscope (SEM), X-Ray Diffractometer (XRD) and Fourir Transform Infra Red (FTIR) spectrometers were used to characterize the nanoparticles produced before being tested for antioxidant activity. The results showed that the absorbance value increased with increasing reaction contact time. The maximum uptake was obtained at wavelengths of 432-446 nm using a UV-Vis spectrophotometer. The particle size was determined using a PSA with an average particle size distribution of 45.7 nm. The average diameter of silver nanoparticles was 10.06 – 13.97 nm and the silver nanoparticles had rod-shapes. Functional groups that play a role in the synthesis of nanoparticles were –OH, –C=O, and –C-O groups. Silver nanoparticles inhibited free radicals as antioxidants with the IC50 value of 582.7 ppm

POTENSI PRODUKSI BIOFUEL DARI BIOMASSA FITOPLANKTON LAUT SPESIES Chlorella vulgaris, Dunaliella salina DAN Spirulina sp., YANG DITUMBUHKAN DALAM NUTRIEN UNGGUL “MSSIP” TERINDUKSI ION LOGAM Fe, Co, DAN Ni

Research about composition of superior nutrients, growth parameters, and best method to maximize production of biomass sea phytoplankton, Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. has been performed. The nutrients was named as MSSIP which were consist of following compositions: urea fertilizer, Arschat-M nutrient, Fe:Co:Ni metal ions (6 : 3 : 9 : 6 : 3). Methods used were identification and analysis of sea phytoplankton.  Determination of optimum growth condition, pure culture, and mass culture were using local raw materials-based engineered nutrients or MSSIP (M. Sjahrul-Syahruddin Kasim-Indah Raya-Paulina Taba). Determination of product density of sea phytoplankton biomass, analyses of carbohydrate content, and lipid biomass were done by using haemocytometer and microscope, Luff Schrol method, and soxhlet method (n-hexane as solvent), respectively. Morphology of phytoplankton was identified by using a digital camera microscope, SZ60/sZ60-61. Furthermore, to understand the effect of metal ions, Fe, Co, and Ni added into MSSIP nutrient, identification of nutrient before and after culturing process were done using XRF-Thermo-Fisher.  The results showed that Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. were suitable as raw materials  to produce biofuel. Those three phytoplankton contained 0,3095 g/L, 0,3782 g/L, and 0,3325 g/L biomass, 32,49%w/w, 31,58%w/w, and 29,81%w/w carbohydrates; and  25,95%w/w, 26,82%w/w and 24,53%w/w lipid, respectively. Best optimum condition of culture were salinity of 30-35%, temperature of 20-30 °C, pH of 8-9, initial density of 2.5 x 104 cell/mL, light exposure of 40 watt, and continuously aerated with CO2. Based on our study, sea phytoplankton, Chlorella  vulgaris, Dunaliella salina, and Spirulina sp. have a high potency as source of bioethanol and biodiesel.Keywords: mass culture, superior nutrient MSSIP, sea phytoplankton biomass, Fe, Co, Ni metal ion
