Abstract

Thesynthesis ofcaffeic acid phenethyl ester (CAPE) and its characterization using 1H NMR has been carried out. This research aims to discloseseveral potential ways of CAPE synthesis.The study was conducted by reacting some precursors in effort to produce CAPE.The progress of the synthesis was monitored using TLC and the characterization of the synthetic products was performed with 1H NMR.Three different approaches in effort to synthesize CAPE were conducted.The first approach was a direct rection between caffeoyl chloride and phenethyl alcohol. The second approach was including a protection using benzyl group and the last one was utilizing acetyl protecting groups where both these protecting groups were used to protect the catechol groups of the caffeic acidmoiety. However, the first and second methods failed to achieve the compound target, CAPE. There was only one procedure hasbeen successful, namely the reaction between phenethyl ester with acetyl-protected caffeic acidresulting inthe production of the synthetic compound target, CAPE, as much as 42%

Abstract

Research on the synthesis of methyl ester nitrate from nyamplung seed oil (Calophyllum inophyllum L.). The aims of study are to are to determine the nitrate methyl ester can be synthesized from nyamplung seed oil determine the yield of the transesterification and nitration reaction from nyamplung seed oil. In this study nyamplung seed oil was obtained from pressing nyamplung seeds using a hydraulic press, then the crude oil obtained was subsequently degumming to remove gum. Free oil of the etherified gum then transesterification with methanol. The transesterification results are then titrated and produce nitric methyl esters. Characterization of nitric methyl ester  by spectrophotometer IR shows functional groups C-ONO2, C=C dan C-NO2 at wave number 1635,64 cm-1 1550,77 cm-1 dan 1365, 60 cm-1. The yield of transesterification of nyamplung oil was 64.66% and the nitration yield was 10.6%.

Abstract

ABSTRAKDesa Abenggi merupakan salah satu desa di kecamatan Landono kabupaten Konawe Selatan yang dahulunya dikenal sebagai sentra pertanian, namun saat ini para petani di desa tersebut beralih menjadi pengrajin batu merah. Perkembangan usaha pembuatan batu merah di desa Abenggi menyebabkan luas lahan pertanian semakin sempit sehingga produktivitas dari sektor pertanian semakin menurun. Kegiatan pengabdian kepada masyarakat terintegrasi KKN-Tematik bertujuan untuk introduksi teknologi budidaya tanaman hortikultura dan memberdayakan masyarakat khususnya pemuda karang taruna untuk meningkatkan pengetahuan dan keterampilan dalam mengelola dan memanfaatkan lahan pekarangan menjadi lahan produktif melalui budidaya pepaya California. Metode yang digunakan adalah partisipasi aktif semua pihak yang terlibat dalam kegiatan ini melalui pelatihan dan pendampingan kepada masyarakat. Kegiatan diawali dengan penyuluhan mengenai teknik budidaya Pepaya Clifornia dan sharing pengalaman dengan kelompok petani lokal serta pelatihan penyiapan bibit unggul dan teknik penanaman pepaya California pada lahan pekarangan. Kegiatan pengabdian yang dilaksanakan dalam bentuk kolaborasi antara dosen dan mahasiswa KKN di desa Abenggi yang dilaksanakan selama satu bulan menunjukkan peningkatan pengetahuan dan kemampuan masyarakat dalam memanfaatkan lahan pekarangan yang tidak terpakai untuk budidaya pepaya California.    Kata kunci: budidaya; pepaya california; lahan pekarangan; desa Abenggi ABSTRACTAbenggi Village is one of the villages in Landono subdistrict, South Konawe district, which was previously known as an agricultural center, but now the farmers in the village have turned into red stone craftsmen. The development of the red stone manufacturing business in Abenggi village has caused the area of agricultural land to become increasingly narrow so that the productivity of the agricultural sector continues to decline. The integrated KKN-Thematic community service activity aims to introduce horticultural plant cultivation technology and empower the community, especially youth organizations, to increase their knowledge and skills in managing and utilizing home garden land into productive land through cultivating California papaya. The method used is the active participation of all parties involved in this activity through training and assistance to the community. The activity began with counseling regarding California papaya cultivation techniques and sharing experiences with local farmer groups as well as training in preparing superior seeds and techniques for planting California papaya in home gardens. Service activities carried out in the form of collaboration between lecturers and KKN students in Abenggi village which were carried out for one month showed an increase in community knowledge and ability in utilizing unused home garden land for cultivating Californian papaya. Keywords: abenggi village; californian papaya; cultivating;  home garden
