Abstract

This research heads for examining the effectiveness of acetone extract of cinnamon leaf  (Cinnamomum burmanni Blume) to the growth of Fusarium soloni fungus. Cinnamon leaf which was used in this research grows in Bedugul village Tabanan regency Bali province. The extract effectiveness experiment of cinnamon leaf to the fungus experiment  was carried out by well difusion method in Biopesticide Laboratory of Agriculture Faculty Udayana University, by using the complete random plan consists of 6 treatments and 4 times refrains. The concentration treatment of acetone  extract of cinnamon leaf obviously (P<0.05) can impede the growth of colony, biomass and establishment of experiment fungus spore i.e. Fusarium soloni in accordance with in-vitro by PDA and PDB media. Extract minimum blocked energy of cinnamon leaf in experiment fungus i.e. 0,5%. The extract of cinnamon leaf obviously can impedethe growth of colony, spore establishment and biomass establishment of experiment fungus. In extract concentration treatment 0.5% obviously can impede the colony growth of experiment fungus, spore establishment and fungus biomass establishment i.e. each of them in amount of  17,3%, 41,45% and 7,94% if they are compared by the control. The higher extract concentration then the blocked energy is the bigger.

Abstract

Penelitian dilaksanakan di wilayah Desa Peliatan, Kecamatan Ubud, Kabupaten Gianyar-Bali tahun 2005-2006.Penelitian dilakukan dengan menyelusuri jalur-jalur jalan yang ada di wilayah desa sambil mencatat jenis herba dan lianayang ditemukan. Tumbuhan ini ini kemudian dicek statusnya (dilindungi atau tidak), pemanfaatan, serta mitos yangberkembang dalam masyarakat tentang tumbuhan tersebut. Dari hasil studi ini telah berhasil diidentifkasi 100 jenis herbadan liana. Dilihat dari segi pemanfaatanya, bagian terbesar dari herba dan liana ini, yaitu mencapai 50% pemanfaatannyamerupakan kombinasi dari tanaman hias, bahan makanan, tanaman upakara serta campuran antara tanaman upakara danbahan makanan. Sebanyak 40% dimanfaatkan untuk penggunaan lainnya, serta 10% sisanya merupakan gulma, yangrelatif belum dimanfaatkan secara nyata oleh masyarakat. Dilihat dari segi mitosnya, 12% dari tumbuhan herba dan lianadi Desa Peliatan memiliki mitos. Sepuluh (10) jenis (atau 83% diantaranya) mempunyai mitos atau kepercayaan yangbernilai positif sedangkan yang negatif hanya 2 jenis (17 %). Dilihat dari segi perlindungan, maka dari jenis-jenis herbadan liana tersebut tidak ada yang termasuk jenis-jenis yang dilindungi peraturan perundang-undangan yang berlaku diIndonesia.

Research on weed inventory in maize land aims to see the diversity of existing weeds growing on the area of ??corn (Zea mays (L.)) in the fields of Bongkasa Abiansemal Badung Village, Bali Province. This observation will be expected to obtain information about the types of weeds that exist, so that weeds and control of weeds in corn (Zea mays (L.)) are optimally implemented. The study was conducted from June to August 2018. In observations using an exsplorating sampling method. In order to produce better and more systematic results, observations were made to make lanes and observations on the research land so that it could easily observe the growth of disturbing plants growing on the observed maize crops. In a 1-month old corn plant, 8 tribes were found with 16 species. In the 2month old corn plant, 14 tribes were found with 28 species of weeds, while in the 3-month-old maize there were 22 tribes with 40 species of weeds.

INTISARI Keberadaan gulma pada tanaman padi akan menyebabkan penurunan produksi apabila gulma tidak dikendalikan secara efektif, karena dapat mempengaruhi pertumbuhan dan menurunkan produksi tanaman pangan. Penelitian ini bertujuan untuk mengetahui keanekaragam jenis gulma yang tumbuh pada tanaman padi (Oryza sativa L.) di Desa Cempaga, Kecamatan Bangli, Kabupaten Bangli, mengetahui jenis gulma yang tumbuh pada tanaman padi (Oryza sativa L.), dan jenis gulma apakah yang dominan pada tanaman padi (Oryza sativa L.). Penelitian ini dilaksanakan di Desa Cempaga Kecamatan Bangli Kabupaten Bangli pada bulan Maret-Mei 2020. Pengumpulan data dilakukan dengan analisis vegetasi menggunakan metode kuadrat dengan cara random menggunakan lotre atau undi dimana pengambilan sampel dilakukan sebanyak tiga kali yaitu pada minggu ke-8, ke-10, dan ke-12 dengan interval waktu pengambilan yaitu sekali dalam 2 minggu sehingga jumlah sampel yang diambil setiap 2 minggu yaitu 15 plot dengan ukuran 1x1m, dan data yang diambil yaitu jenis gulma yang terdapat didalam plot. Hasil pengamatan keberadaan jenis gulma menunjukkan bahwa jenis-jenis gulma yang tumbuh di lokasi penelitian cukup bervariasi, terdapat 781 individu, 12 jenis dan 8 suku, dimana gulma yang paling banyak muncul di plot yaitu tumbuhan Pusut-pusut muncul di 23 plot dan memiliki dominansi relatif yaitu sebesar 49,31%, sedangkan gulma yang paling sedikit muncul yaitu Paku Rawa hanya muncul di satu plot dengan memiliki nilai dominansi relatif yaitu 0,00%. Dimana artinya tumbuhan yang paling berpotensi mengganggu tanaman pokok yaitu tumbuhan Pusut-pusut dengan pola penyebaran yang mengelompok. Nilai INP tertinggi terdapat pada jenis gulma Pusut-pusut dengan nilai sebesar 103.45%. Kata Kunci : Desa Cempaga, Gulma, Padi Sawah

Abstract

Capung merupakan serangga yang berperan penting dalam keseimbangan ekosistem, berperan sebagai bioindikator dan predator. Sebagian besar fase hidupnya berada di air dalam bentuk larva. Beberapa jenis capung menempati tipe habitat perairan yang spesifik. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis capung dan pemanfaatan nimfanya sebagai nilai tambah pendapatan di persawahan Bendungan Latu Abiansemal . Metode penelitian yang digunakan adalah metode deskriptif dengan cara koleksi langsung menggunakan jaring serangga (insect net) untuk diidentifikasi. Hasil penelitian menunjukkan bahwa jumlah spesies capung yang ditemukan di sekitar Bendungan Latu sebanyak 7 spesies termasuk kedalam 2 famili dengan kemelimpahan relatif Orthetrum Sabina (47%), Pantala flavescens(44%), Neurothermis terminate (4%), Agriocnemis femina (2%), Neurothemis ramburii, Orthetrum chrysis dan Aethriamanta brevipennis masing masing 1%. Pola penyebaran capung 4 spesies mengelompok dan 3 spesies acak.

Abstract

As a nonformal education institution for students that dropped-out of schools, pusat kegiatan belajar masyarakat (PKBM) plays important role in promoting the spirit of lifelong learning and community learning. One of the fundamental components of education, either formal or nonformal, is writing. The ability to write, especially scientific writing, is not an inborn talent but acquired. Results of interview conducted in early February 2019 concluded the followings. First, students are not capable of doing scientific writing correctly. This can be seen from their inability in creating cohesive and coherence sentences. Second, the students seem to lack confidence when participating in writing competition held regularly by Kemdikbud. Finally, the workplace often requires employees to make correspondence and written reports. One way to improve students’ ability to write scientifically is through basic scientific writing workshop. This community service started by giving questionnaires to students which consists of an informal writing about themselves and a scientific writing about social phenomenon. The next step is delivering workshop, giving posttest, and doing workshop evaluation. Based on our evaluation we conclude that the workshop can improve students’ ability to write scientifically.
