“…The population in this study were all families who were in the working area of the Langara Health Center as many as 2,007 families. A sample of 331 people with sampling using the Lemeshow formula (6). Table 1 shows that from 331 respondents, there are 218 respondents (65.9%) who have husband's support in the quite supportive category including 139 respondents (63.8%) using contraceptives in the category of using and using contraceptives in the category of not using 79 respondents (36.2 %).…”

Background: Based on an initial survey in Langara communities showed that from 15 communities in Langara Health Center, their husband gave les support to use a contraceptive tool. Then the mothers said that because of the lack of support from their families with the reason that their husbands complained during sexual intercourse, the husbands were afraid of the side effects of contraception used by their wives. Some of the mothers said they had an unpleasant experience due to weight changes. In addition, the Langara community still lacks knowledge about contraceptives, health facilities are still far from residents' homes. The use of contraceptives plays an important role as the main decision maker regarding the choice of contraception.This study aims to analyse the relationship between husband support and mass media on the usage of contraceptive tools in Langara Public Health Centre in Island Konawe District. Methods: Type of quantitative research with cross sectional approach. The population in this study were all families who were in the working area of the Langara Health Center as many as 2,007 families. A sample of 331 people with sampling using the Lemeshow formula. Results: The results of the statistical test of the husband's support variable show the value of X2 count = 18.21 > X2 table = 3.841 and the value of Phi (Φ) = 0.354 and the mass media variable X2 count = 16,426 > X2 table = 3.841 and the value of Phi (Φ) = 0.522. Conclusion: There is a relationship between husband's support and mass media with the use of contraceptives in the work area of the Langara Health Center, Konawe Islands Regency.

The wide existence of fractures makes conformance control by polymer gels more challenging in water-flooded oil reservoirs. Selection of an applicable gel system and design of an intelligent approach for gel treatment are key components for a successful field application. Moreover, selecting the candidate wells and determining the injection volume of gel are also critical to the success of gel treatments. A gel system with adjustable polymer concentrations was applied for conformance control in fractured tight sandstone reservoir, and notably, less than 5% of syneresis was detected after aging for one year at reservoir condition. The viscosity and the gelation time of this gel system can be adjusted according to the targeted reservoir conditions. The pilot test was conducted in Huabei oilfield (China), and the oil recovery after water flooding was only about 20% original oil in place (OOIP). With further exploitation of the oil field, the majority of the reservoir has suffered from poor sweep efficiency and extremely high water cuts. To characterize the distribution of fractures, the seismic coherence cube was utilized. In addition, the pressure transient test, interwell tracer test and the injection-production data were used collaboratively to determine the volume of fractures in the reservoir. The option of gel formulation and the determination of operational parameters are mainly based on the wellhead pressure. According to the seismic coherence cube, the zone of candidate well group shows a weak coherence state, indicating that numerous fractures exist. Furthermore, there is good continuity between the candidate injection well and the production well. According to the pressure transient test, the volume of re-open fracture is about 1730.9 m3, while the volume of micro-fracture is about 4839.4 m3. Comparably, based on the interwell tracer test, the estimated volume of fractures is approximately 3219.7 m3. Consequently, the designed volume of gel for treatment is 1500.0 m3 in total. The properties of gel slugs were carefully designed, which was tailored to the specific wellbore conditions and formation characteristics. Three months after the gel treatment, the average oil production was increased from 0.36 t/d to 0.9 t/d, and the water cut was decreased from 95.77% to 88.7%. The improved oil production was still benefited from this gel treatment after one year. This study provides a comprehensive approach, from optimization of gel formulation, followed by selection of candidate wells, to calculation of the injected volume, to design the viable operational parameters, for gel treatment field application in fractured reservoirs. It shows that, besides a gel system with superior properties, a suitable injected volume of gel may enhance the chance of success for gel treatments.
