An experimental study to modify Sterculia foetida L. oil (STO) or the corresponding methyl esters (STO FAME) to branched ester derivatives is reported. The transformations involve conversion of the cyclopropene rings in the fatty acid chains of STO through various catalytic as well as stoichiometric reactions. Full conversion of the cyclopropene rings was obtained using Diels-Alder chemistry involving cyclopentadiene in water at 408C without the need for a catalyst. Olefin metathesis reactions were performed using a Grubbs 2nd generation catalyst and cyclopropene ring conversion was !99 and 54 mol% with 2,3-dimethyl-2-butene and 1-octene, respectively. Oxidation reactions were performed using established epoxidation (Sharpless) and dihydroxylation (Prilezhaev) protocols using aqueous hydrogen peroxide as the oxidant. For both reactions, full conversion of the cyclopropene rings was obtained at RT to yield the corresponding a,b-unsaturated ketone in good selectivities. Rearrangement reactions of the cyclopropene rings to the corresponding conjugated diene were successfully performed using homogeneous and heterogeneous palladium catalysts. Excellent conversions (!99%) were obtained using homogeneous palladium catalyst in a biphasic cyclohexane-water mixture (1:1) at 908C. Relevant cold flow properties of all products were determined and compared to crude STO and STO FAME. Best results were obtained for the metathesis products of STO with 1-octene, with a cloud point (CP) and pour point (PP) of À128C.Practical applications: The S. foetida L. tree produces a tropical oil with high potential to be converted to various oleochemical products. The oil contains cyclopropene rings in the fatty acid chains which are known to be very reactive and as such excellent starting materials for various chemical modification reactions. We here report an experimental study on the modifications of STO into novel branched ester derivatives which are prospective products for a range of applications. Examples are the use as cold-flow improvers for biodiesel or biolubricants (ester derivatives with long, aliphatic branches), as reactive building block material for resin, coatings and/or packaging application (derivatives containing unsaturated (cyclic) structures in the fatty acid chains).

This study aims to analyze the improvement of the operational performance of Indonesia’s Soekarno-Hatta Airport train through service quality which is mediated by train passenger loyalty and passenger satisfaction. The main problems in this study are the use of the same railway for long-distance train, airport train, and commuter Line train, the limited use of airport railway with four schedules, the headway which becomes 30 minutes since the number of travels becomes 82 trips, and the tariff being applied now is considered as burdening the passengers. The research method uses a quantitative analysis approach with the technique of Structural Equation Modeling-Lisrel. Data collection is done through observation and questionnaire distribution. The respondents are 306 passengers of trains heading for Soekarno-Hatta Airport. The benefit of this study for the domestic railway company is that by improving service quality, passenger loyalty and satisfaction, it will improve the operational performance of airport trains. The result of this research indicates the significant influence of service quality variable on passenger loyalty through passenger satisfaction, the significant influence of service quality variable on operational performance through passenger satisfaction and passenger loyalty as well as the significant influence of passenger satisfaction variable on operational performance through passenger loyalty.

<p><em>This research is on the manufacturing and logistics industry in Indonesia in improving environmental performance. This study aims to implementation of lean management and green supply chain management to environmental performance. The methodology used in this study is primary data, 150 respondents from logistics professionals. This study uses SEM-PLS. The results showed that lean management had no significant effect on environmental performance. The implications of this study are focused on geography and small samples.  Green supply chain management is oriented towards the environment in making supply chain decisions to improve environmental performance. </em></p>

The term patriarchy is used to refer to "male power" specifically the power in which male domination of women occurs which is realized in various ways. Men are considered to have more power than women so that people view women as weak and helpless. However, with the participation of women who echoed the spirit of movement in countering the injustice of patriarchal culture, this social change was taken by the media to be socialized through propagation media that focused visual auditivity, for example in films. The paper thesis was intended to look for signs of resistance (resistance) to patriarchal culture in the components of the filmThis research is a qualitative research with qualitative descriptive method, namely by conducting research on signs of resistance against patriarchal culture on the components of Kartini's film. The analysis unit to be used is the scene. The results of the research data are processed by qualitative analysis which is encoded by the three-level theory of social code proposed by John Fiske so that conclusions can be drawn.Based on the results of  the study it can be concluded that some film components show signs of resistance to culture such as wardrobe, movement, sound, music, editing, arrangement, and cinematography. These signs after coding are done using the Three levels of the Social Code showing women's representation of the culture of the Patriarchy.Keywords: Resistance, Women, Patriarchal Culture, Signs, Film Components  ABSTRAKIstilah patriarki digunakan untuk menyebut “kekuasan laki-laki” khususnya kekuasan yang didalamnya berlangsung dominasi laki-laki atas perempuan yang direalisasikan melalui berbagai cara. Laki-laki dianggap memiliki kekuatan lebih dibanding perempuan sehingga masyarakat memandang perempuan sebagai seorang yang lemah dan tidak berdaya. Namun seiring dengan banyaknya perempuan yang mendengungkan semangat pergerakan dalam melawan ketidakadilan budaya patriarki, gejala sosial ini ditangkap oleh media untuk disosialisasikan kedalam proyeksi media yang bersifat auditif visual, contohnya pada film. Skripsi karya tulis berjudul “Resistensi Perempuan Jawa Terhadap Patriarki (Analisis Makna Tanda Pada Film Kartini)” ini bertujuan untuk mencari tanda-tanda resistensi (perlawanan) terhadap budaya patriarki didalam komponen-komponen film.Penelitian ini merupakan penelitian kualitatif dengan metode deskriptif kualitatif, yaitu dengan melakukan pencarian tanda-tanda resistensi (perlawanan) terhadap budaya patriarki pada komponen-komponen film Kartini. Unit analisis yang akan digunakan adalah scene. Data hasil penelitian diolah dengan analisis kualitiatif yang dikodekan dengan teori three level of social codes yang dikemukakan oleh John Fiske sehingga bisa ditarik beberapa kesimpulan.Berdasarkan hasil kajian dapat disimpulkan bahwa beberapa komponen- komponen film menunjukan tanda-tanda resistensi (perlawanan) terhadap budaya patriarki seperti wardrobe, pergerakan, sound, musik, editing, setting, dan sinematografi. Tanda-tanda tersebut setelah dilakukan pengkodean menggunakan Three level of Social Codes menunjukan representasi perlawanan perempuan Jawa terhadap budaya Patriarki.Kata Kunci : Resistensi, Perempuan, Budaya Patriarki, Tanda, Komponen Film
