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.

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.

Abstract

Jagung (Zea mays L.) merupakan salah satu tanaman pangan penghasil karbohidrat yang terpenting di dunia. Salah satu permasalahan dalam produksi jagung adalah penurunan kuantitas dan kualitas jagung akibat adanya gulma yang tumbuh di sekitar tanaman jagung. Penelitian ini bertujuan untuk mengetahui struktur dan komposisi gulma di lahan jagung Desa Belayu, Kecamatan Marga, Kabupaten Tabanan, Provinsi Bali. Metode yang digunakan dalam penelitian ini adalah metode kuadrat (Quadrat methode sampling) denganplot berukuran 1x1 m. Data dianalisis menggunakan parameter vegetasi yang terdiri dari Indeks Nilai Penting (INP), indeks keanekaragaman (H’), indeks dominansi (C), indeks kemerataan (E), dan indeks similaritas (IS). Hasil yang didapat yaitu komposisi gulma yang ditemukan pada minggu ke-3 yaitu 18 spesies dari 9 suku, pada minggu ke-6 yaitu 25 spesies dari 16 suku, dan pada minggu ke- 9 yaitu 31 spesies dari 19 suku. Nilai INP tertinggi ditemukan pada Cyperus rotundus L dari suku Cyperaceae pada minggu ke-3, ke-6, dan ke-9 . Indeks keanekaragaman (H’) gulma tergolong sedang berkisar 2,29-2,77, indeks dominansi (C) menunjukkan tidak ada gulma yang mendominansi dengan nilai berkisar 0,09-0,13, indeks kemerataan (E) menunjukkan bahwa jenis-jenis gulma tergolong merata dengan nilai berkisar 0,78-0,80, dan indeks similaritas (IS) sebesar 72,9% yang menunjukkan bahwa similaritas spesies gulma disetiap minggu dikategorikan tinggi.

Abstract

An attempt to avoid formalin side effects of toxin dose contained in food is to administer hepatoprotectant. Moringa is one of the food sources that functions as a hepatoprotector. The purpose of this study was to determine the activity of Moringa leaf tea (steeping water) as an antioxidant and hepatoprotector in male white rats induced with formalin doses of toxicity. The method used in this study was a randomized group design (RGD). The liver damage barrier test used a formalin-induced male white rat model (0.100 ml/BB) as a negative control, tea (steeping water) of Moringa leaves was given at a dose of 50, 75, 100 mg/BB once a day and the administration of aquades as a positive control for 7 days. The formalin-induced group of mice showed a significant increase in SGPT, SGOT and MDA values compared to positive controls. Orally administering Moringa leaf tea (steeping water) can weaken or decrease the increase in SGPT, SGOT and MDA values in male rats compared to formalin-induced significantly. So that giving tea from steeping water Moringa leaves can be an alternative as drinking water after meals. Keywords: toxic, SGOT, SGPT, MDA

Abstract

The growth of red chili plants (Capsicum annuum L.), is impacted by both environmental factors and nutrition availability. Ecoenzymes have the ability to lower global warming and meet plant nutrient needs. The research was conducted to analyze the vegetative growth of red chili plants after being given ecoenzyme treatment and gradual watering. Red chili seeds are sown for 4 weeks, then transferred to polybags. The research used a two-factor factorial randomized block design method, namely administering ecoenzymes with a concentration of 0%; 0,5%; 1%; 1,5% and watering gradually by giving water every day; twice a day; once in three days. Every combination of treatments was carried out three times. The study's findings demonstrated that, two weeks after seeding, an ecoenzyme concentration of 1,5% could provide the maximum germination capacity (90%) of any concentration. Age 12 Weeks After Planting in polybags, the maximum plant height (70,16 cm) at 0% ecoenzyme concentration and daily watering; the quantity of primary branches (10,78 branches) at 1,5% ecoenzyme concentration and daily watering. Age 16 Weeks After Planting, the largest leaf area (105,13cm2) measured using Image-J when applying an ecoenzyme concentration of 0% and watering every day (control); root length (28,33cm) in the treatment of 1,5% ecoenzyme concentration and watering every three days; The shoot dry weight was the greatest (3,29 g) and the root dry weight was the greatest (0,67 g) when the ecoenzyme concentration was 1.5% and watered every day. Treatment with an ecoenzyme concentration of 1.5% and daily watering exerts the best influence on the growth of red chili plants. Keywords: Liquid fertilizer, leaf area and image-J
