Abstract

The present study was conducted to elucidate the activity of essential oil from rhizome extracts of Acorus Calamus Linn as an herbal insecticide against Plutella xylostella Linn pests. The oil from the Acorus Calamus roots was extracted by a water steam distillation method and found 0.005% content. Antifeedant testing was performed by trial option, while insecticidal activity was carried out by feeding and contacting methods. The results showed that the oil have activity as an herbal insecticidal and as an appetite inhibitor to the Plutella xylostella Linn pests. The maximum resistance index values ​​obtained from eating essential oils at concentrations of 4.0% was equal to 80.815%. The toxicity values of the oils, reported as LC50, ​​ as insecticides by the feeding trial and contacting methods were 1.33% and 1.27%, respectively. Those results conclusively indicated that the essential oils of the Acorus Calamus Linn potentially protect the cabbage leaves from the Plutella xylostella Linn pest attacking.

Abstract

Plastic waste is a topic that is always discussed in academic studies, especially regarding for the environment. Plastic waste causes natural damage whether it is biotik or abiotik environment. Lack of understanding of the plastic waste dangers caused tless of the environment concern. This is illustrated by the behavoir of throwing plastic waste not on the rubbish bin. By the socialization of  plastic waste education and its utilization, it is expected can improve the intellectual understanding about the risk of plastic waste. This activity was initiated by a group of young people in the Kupang city whose joined to the community of "Saya Pilih Bumi" in Kupang regional by involving speakers from Widya Mandira Catholic University of Kupang City.  The method of carrying out the socialization activities is by surveying and requesting permission to the school, then two activities are carried out there are education of plastic waste and plastic waste treatment. The success of these program was  indicated by the students enthusiasm in the discussion session and the results of processing plastic waste yield some goods like flower pots, pencil cases and other accessories.abstrakSampah plastik adalah topik yang selalu dibahas dalam studi akademik, terutama mengenai lingkungan. Sampah plastik menyebabkan kerusakan alam baik itu lingkungan biotik atau abiotik. Kurangnya pemahaman tentang bahaya limbah menyebabkan kepedulian yang rendah terhadap lingkungan. Hal ini digambarkan oleh kebiasaan membuang sampah tidak pada tempatnya. Melalui kegiatan edukasi sampah plastik dan pemanfaatannya, diharapkan dapat menumbuhkan kesadaran intelektual akan bahaya sampah plastik. Kegiatan ini diprakarsai oleh sekelompok anak muda di kota Kupang yang tergabung dalam komunitas "Saya Pilih Bumi" regional Kupang dengan melibatkan pembicara dari Universitas Katolik Widya Mandira Kupang. Metode pelaksanaan kegiatan sosialisasi adalah dengan melakukan survey dan meminta izin ke sekolah mitra, Kemudian dilakukan dua kegiatan yaitu edukasi sampah dan pengolahan sampah plastik. Indikator ketercapaian pelaksanaan kegiatan ini adalah antusiasme siswa dalam sesi diskusi dan hasil pengolahan sampah plastik dalam bentuk fas bunga, tempat pensil dan aksesoris lainnya.

Abstract

Although the current situation is relatively conducive, a new problem has emerged in the form of a decrease in students' comprehension and understanding of their learning, as happened at GMIT Naioni Elementary School and Tiga Putera Elementary School. It was found that third and fourth graders had difficulty understanding Science due to limited interaction, incomplete explanations, and difficulties in reading texts. Using a focused group discussion approach with the main objective of looking at the attitudes, beliefs, and reactions of respondents more holistically, this service activity is carried out. It can be seen that this activity went well marked by the enthusiasm of the students when competing. Some students who have difficulty reading are helped by the teacher and the committee team, resulted in presenting well in front of the judges. Moreover, a conducive and competitive learning climate is created when students look at the trophy with burning ambition. In conclusion, this service activity was successful. It can be seen from the third and fourth grade students of SD GMIT Naioni and SD Tiga Putera’s enthusiasm and motivation to compete and participate in the science script reading competition as well as the understanding of science that is starting to form, by the skills of the students when telling stories of the script quickly and precisely.

Abstract

Penelitian ini dilakukan dengan tujuan untuk mengetahui profil senyawa-senyawa metabolit sekunder dalam minyak atsiri daun tumbuhan legundi (Vitex trifolia Linn) yang tumbuh di Pulau Timor. Minyak atsiri dari sampel daun tumbuhan legundi diekstraksi menggunakan distilasi uap air dengan menggunakan sampel yang masih segar sedangkan analisis senyawa metabolit sekunder dalam minyak atsiri dilakukan dengan GC-MS. Hasil penelitian yang terdapat dalam sampel minyak atsiri daun legundi asal Pantai Paradiso, Kelurahan Oesapa Barat, Kota Kupang sebanyak 49 senyawa. Senyawa-senyawa yang dominan ada 12 yakni trans- Kariopillen 25,43%, 1,2-asam Benzendikarbosilik 14,16%, Sabinen 7,57%, 1,8-Sineol 4,17%, Kariopillen oksida 3,71%, Skareol 3,21%, α-Humulen 3,07%, α-Terpinenil asetat 2,36%, Sitronella 2,30%, 3-Sikloheksanol 1,76%, α-Pinen 1,76%, β-Pinen 1,68%.
