Abstract

Patchouli is the largest non-oil export commodity among essential oil exports in Indonesia. However, the quality of patchouli oil in Indonesia is considered to be very low. Traditional patchouli oil distillation is carried out in a small capacity and uses a simple distillation method based on a large difference in boiling points or one of the volatile components. This process produces poor quality patchouli oil such as acid number more than 8, dark oil, patchouli alcohol less than 30%, and high water content. This is evidenced by the large amount of Fe metal contained in patchouli oil. Patchouli oil produced contains a lot of iron in its yield, so it needs further processing to reduce the Fe content in patchouli oil. The use of resin as an adsorbent for Fe metal is one way to reduce the Fe metal content. Resin weighing 50, 150 and 250 grams was added to 200 ml of patchouli oil. Then the stirring process was carried out with a stirring speed of 200 rpm with time variations of 30, 60 and 90 minutes. The results obtained showed the best adsorption process with Fe content in patchouli oil of 1.42 mg/Kg, contact time of 90 minutes and amount of resin of 250 grams with the largest percentage of removal of 87.5%. Keywords: Patchouli oil, Ion Exchange, Resin.

Thisresearch was studied using Nurgiyantoro's literary structuralism theory. The purpose of thisstudy was to determine the background of Prabu Baka's attack and Prabu Baka's strategy indefending his territory. The source of data in this study is the Prambanan Babad Manuscriptwith library research data collection techniques. This research uses historical methods with amultidimensional approach. As a result of this study, it is known that Prabu Baka got a triggerthat became the background of his attack. In his attack, Prabu Baka had a good strategy andtactics so that he could repulse the opposing forces, as stated in the Prambanan Babad script.Some of the strategies and tactics used by Prabu Baka were to change the weapons used in thewar and choose war leaders who were truly competent in leading the war.Keywords: strategy, war, Babad Prambanan Dalam realitas kehidupan yang terjadi lingkungan sekitar kita menunjukkan bahwadibutuhkannya seorang pemimpin untuk memimpin suatu lingkup tertentu. Dalam suatulingkup tersebut, pemimpin yang terpilih dianggap memenuhi kriteria dalam sifat sifatkepemimpinan. Strategi yang digunakan oleh para pemimpin tersebut juga bermacam-macamjenisnya. Penelitian ini dikaji menggunakan teori strukturalisme sastra Nurgiyantoro. Tujuandari penelitian ini ialah untuk mengetahui latar belakang serangan Prabu Baka dan strategiPrabu Baka dalam mempertahankan daerah kekuasaannya. Sumber data pada penelitian iniadalah Naskah Babad Prambanan dengan Teknik pengumpulan data studi Pustaka (libraryresearch). Penelitian ini menggunakan metode sejarah dengan pedekatan multidimensional.Hasil dari penelitian ini, diketahui bahwa Prabu Baka mendapat pemicu yang menjadi latarbelakang penyerangannya. Dalam penyerangannya, Prabu Baka memiliki strategi dan taktikyang baik sehingga dapat memukul mundur pasukan lawan, seperti yang tertera di dalamnaskah Babad Prambanan. Beberapa strategi dan taktik yang digunakan oleh Prabu Baka ialahdengan mengubah persenjataan yang digunakan di dalam peperangan dan memilih pemimpinperang yang benar-benar kompeten dalam memimpim peperangan.Kata kunci: strategi, peperangan, Babad Prambanan
