Petroleum pollution has bad impact for life in marine ecosystems, particularly in coastal areas. One method of handling the pollution is bioremediation using bacteria that are able to degrade and utilize petroleum hydrocarbons as carbon source. One technique of bioremediation is biostimulation, that is the addition of nutrients that can improve the process of oil degradation by degrading bacteria. Nutrient slow-release fertilizer are used, one of which is Gramafix. The purpose of this study was to determine the optimal concentration of Gramafix in increasing degradation of petroleum contaminants by indigenous bacteria. Four concentrations of Gramafix as treatments are P1 (0,085 g), P2 (0,171 g), P3 (0,341 g) and P4 (0,682 g), as well as the negative control treatment (no fertilizer and bacteria) and positive control (with bacteria, without fertilizer). Observations were carried out four times, on 0, 7, 14 and 28 days of incubation. The parameters used are heavy oil using the gravimetric method, the total number of bacterial cells using Acridine Orange Direct Counting and environmental factors such as nitrogen contents, phosphorus contents, temperature, dissolved oxygen, pH and salinity. Analysis of the data using a completely randomized design (CRD) with ANOVA and Duncan test. The results showed the P3 can improve the process of oil degradation by bacteria that degrade the highest percentage of 65,91% in the 28 days of incubation, it also has more bacterial cells than other treatments. The result of this study is the addition of 0,341 g Gramafix is optimum for enhancing the degradation of petroleum hydrocarbons by degrading bacteria. Keywords: Pollution, petroleum, bioremediation, biostimulation, slow-release fertilizer.

The freedom to use Christian religious symbols in Jayapura City creates social unrest and jealousy for other people. This article aims to analyze the religious symbols used by Christians, intense contestation of religious symbols by Christians in Jayapura City, and ideas about its arrangement. This qualitative research uses the paradigm of social phenomenology. This study found that Muslims in Jayapura City is the second largest after Protestant Christianity, but religious development is ranked third after Protestant Christianity and Catholicism. Islam is considered the religion of migrants. The rise of Christian religious symbols in Jayapura City as holy people who have majority control and have freedom of expression in religious symbols is carried out by religious groups in other areas and applied in Jayapura City. The role of central government policy is needed to emerge various ideas in the community in the region. Regional regulations provide freedom for the use of religious symbols. The religious majority who control the government sector has control over the use of religious symbols rather than minority groups by making rules that bind religious communities and raise the exclusivity of the majority group. The local parliament members (DPRD)'s inability to realize the aspirations of the Muslim community of Jayapura City is due to the lack of Muslim members of the local parliament (DPRD). Hence, they have limited numbers in supervising emerging policies, including the use of religious symbols.
