This qualitative case study aims to explore the electoral political relations of the kiai and santri in the local leaders election of East Java.The kiai's authority is absolute, the submission of the santri to the kiai is the main rule of the pesantren culture, the relationship of the kiai and santri is patron-client, there is an unequal interaction with the position of the santri being a client and the kiai becoming a patron.The strength factor of the charisma and influence of the kiai is often used for various interests in the politics of regional elections. Different from theory, the patron-client relationship in the electoral political relations of the kiai and santri in the local leaders election of East Java is not relevant. This study finds, First, the electoral political relations of the kiai and santri are determined by the attitude of equal egalitarian relations and complementary relations. Kiai and santri both play a role in shaping voting behavior, and the kiai is no longer the dominant figure in determining santri's political choices, because there is a practice of political deliberation. Secondly, there are three typologies of electoral political relations between kiai and santri, namely, (1) Political relations are equal (associative), (2) Positive opposition political relations (dissociative-positive), and (3) Political relations mabadi ’khaira ummah ((prioritizing the interests of the ummah). Lastly, this case study of the electoral political relations of the kiai and santri adds new knowledge that the santri's political choices in regional elections are no longer based on patron-client relations.

Pine rosin of Pinus merkusii Jung at de Vriese is produced industrially from a distillation process of pine sap. The high total Indonesian production leads the primary derivatization strategy into several derivates to fulfill the market demand. Abietic acid (AA) is a major compound in pine rosin, used as the object of observation in this study. The general methodology for transformation reported involves using palladium (Pd) and platinum (Pt)-based catalysts. Both are precious metal catalysts to proceed with oxidative dehydrogenative-aromatization of the rosin. The synthesized product provides dehydroabietic acid (DHA) derivatives in high yield. This paper reports that non-precious metal-based catalysts such as iron (Fe), zinc (Zn), or copper (Cu) with iodine (I2) were applied to deliver the reaction by steam cracking without nitrogen (N2) and oxygen (O2) for economical, efficient, and greenway’s catalyst. It was found that a similar product was isolated, including several by-products. Under high temperatures with a various metal transitions and halogen by FeCl3-I2 and Cu(NO3)2.3H2O and ZnCl2 catalyst, four compounds were identified employing spectroscopic methods in the reaction product: 7-hydroxy-dehydroabietic acid (5), 1,7-dihydroxy-dehydroabietic acid (6), 7-isopropyl-1-methylphenanthren-9-ol (7) and polymer (8). This modified pine rosin was mainly used as an emulsifier for the synthetic rubber industry, varnish, ink, paper sizing, etc. The products are determined based on LC-MS/MS, UV-Vis, and ATR-FTIR spectroscopy.
