Abstract

Abstrak Penelitian ini bertujuan menguji efektifitas ekstrak daun sirsak dan daun gamal sebagai pengendali hama walang sangit  pada tanaman padi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 2 perlakuan yaitu jenis ekstrak dan konsentrasi ekstrak. Perlakuan 1 yaitu jenis ekstrak daun (A): sirsak (A1) dan gamal (A2), perlakuan 2 yaitu konsentrasi ekstrak (K): Kontrol (K0), 5% (K1), 10% (K2), 15% (K3), dan 20% (K4). Hasil penelitian menunjukkan bahwa ekstrak daun sirsak efektif terhadap mortalitas walang sangit tertinggi pada konsentrasi 20% (83%) dan yang terendah pada konsentrasi 0% (0 %). Ekstrak daun gamal juga efektif terhadap mortalitas walang sangit tertinggi pada konsentrasi 20% (74%) dan yang terendah pada konsentrasi 0% (0%). Waktu kematian pada hari pertama setelah aplikasi dengan rata-rata mortalitas tertinggi berada pada perlakuan ekstrak daun sirsak 20% (30%) dan daun gamal 20% (28%) dan terendah berada pada perlakuan ekstrak daun sirsak 0% (0%) dan daun gamal 0 % (0%). Kata kunci: daun gamal, daun sirsak, tanaman padi, walang sangit Abstract This study aimed to evaluate the effectiveness of soursop leaf extract and gliricidia leaves as pest control of walang rice (L. acuta) in the rice plants. This study used a completely randomized design (CRD) with 2 treatments, i.e. extract type and extract concentration. The treatment of extract type (A) were soursop (A1) and Gamal (A2), whereas the treatment  of extract concentration (K) were control (K0), 5% (K1), 10% (K2), 15% (K3), and 20% (K4). The results showed that the soursop leaf extract was effective to control sangit walang with the highest mortality was in the concentration of 20% (83%) and the lowest was in the concentration of 0% (0%). Gliricidia leaf extract was also effective to control sangit walang with the highest mortality in the concentration of 20% (74%) and the lowest was in the concentration of 0% (0%). The mortality time was on the first day of the application with the average highest mortality was in the treatment of 20% soursop leaf extract  (30%)and 20% gliricidia leaves (28%) respectively. The lowest mortality was in the treatment of 0% soursop leaf extract (0%) and 0% gliricidia leaves (0%).Keywords: gliricidia leaves, rice plant, soursop leaves, walang rice pest

Abstract

Abstrak   Kupu-kupu merupakan salah satu bagian dari ekosistem yang fungsinya mempertahankan keseimbangan ekosistem dan memperkaya keanekaragaman hayati. Tujuan penelitian yaitu untuk menganalisis kekayaan, kelimpahan, keanekaragaman dan kemerataan spesies di hutan Danowudu, Masarang dan Kawatak, juga membandingkan jenis kupu-kupu berdasarkan topografi pada ketiga lokasi hutan tersebut. Penelitian ini dilaksanakan di hutan Danowudu, Masarang dan Kawatak dan dilanjutkan di laboratorium dari bulan Maret-Juli 2016. Penelitian ini menggunakan metode transek dan rute dibuat sepanjang 1000 m untuk setiap transek. Hasil penelitian menunjukkan bahwa kelimpahan, kekayaan dan keanekaragaman spesies kupu-kupu tertinggi di hutan Danowudu. Kemerataan spesies tertinggi di hutan Masarang. Spesies kupu-kupu yang hanya dapat ditemukan di hutan Danowudu (200-240 mdpl) terdiri dari 13 spesies. Spesies kupu-kupu yang hanya dapat ditemukan di hutan kawatak (827-938 mdpl) terdiri dari 7 spesies. Spesies kupu-kupu yang hanya dapat ditemukan di hutan Masarang (1084-1194 mdpl) terdiri dari 3 spesies. Kata kunci: keanekaragaman, kupu-kupu, Lepidoptera, Sulawesi Utara   Abstract   Butterfly is part of an ecosystem and has function to maintain ecosystem stability and enrich biodiversity. This research aimed to analyze the richness, abundance, diversity and evenness of species in Danowudu, Masarang and Kawatak forest as well as to compare the species of butterflies based on the topography of the three locations of the forest. This research was conducted in Danowudu, Masarang and Kawatak forest and the continued in the laboratory from March to July 2016. This study used a transect method and the route was made as long as 1000 m for each transect. The results showed that the highest abundance, richness and diversity of butterfly species were in Danowudu forest. The highest evenness of species was in the Masarang forest. Butterfly species that was only found in Danowudu forest (200-240 masl) consisted of 13 species. Butterfly species that was only found in Kawatak forest (827-938 masl) included 7 species. Butterfly species that was only found in Masarang forest (1084-1194 masl) comprised 3 species. Keywords: butterfly, diversity, Lepidoptera, North Sulawesi

Abstract

Abstrak Pengembangan tanaman kentang (Solanum tuberosum L.)  unggul untuk menunjang kebutuhan produksi kentang yang terus meningkat membutuhkan tersedianya informasi genetik tanaman kentang yang ada. Informasi keragaman genetik dapat diperoleh menggunakan penanda molekuler RAPD yang dapat mendeteksi keragaman sampai pada tingkat DNA, baik pada daerah penyandi atau bukan penyandi protein dengan cara mendeteksi polimorfik sekuens nukleotida. Informasi yang diperoleh akurat karena tidak dipengaruhi lingkungan.  Penelitian ini bertujuan untuk menganalisis keragaman genetik dari kentang kultivar Superjhon, Atlantik, Dessire, Nadia dan Granola menggunakan penanda RAPD.  Hasil penelitian menunjukkan bahwa dari 14 primer acak yang digunakan hanya 7 yang memberikan pola pita DNA yang polimorfik dan 16 pita dari total 28 pita DNA yang dihasilkan (57 %)  merupakan pita DNA polimorfik. Rata-rata keragaman genetik kentang sebesar 26,8 %. Keragaman genetik terkecil (15,4 %) adalah antara kentang  Atlantic dan Superjhon, sedangkan keragaman terbesar (57,7 %) antara kentang Nadia dan Dessire. Hasil analisis pengelompokan menunjukkan tanaman mengelompok berdasarkan sifat/karakter dan asalnya. Kata kunci: kentang, keragaman genetik, RAPD Abstract The information of potato genetic diversity are required to support the increasing potato demands in the superior potato production. The information of genetic diversity can be obtained using RAPD molecular marker. RAPD can detect the genetic diversity at the DNA level, both in the coding region and non-protein-coding regions by detecting polymorphic sequences in nucleotides. This method provide accurate genetic information because it is not influenced by the environment. This study was conducted to analyze the genetic diversity of potato Superjhon, Atlantic, Dessire, Nadia and Granola using RAPD marker. Amongst the 14 random primers, only 7 primers produced polymorphic banding pattern. Sixteen DNA bands of total 28 existed DNA bands (57%) were polymorphic. The average of genetic diversity was 26.8 %. The smallest genetic diversity (15.4%) was between Atlantic and Superjhon, whereas the greatest genetic diversity (57.7%) was between Nadia and Dessire. The analysis results showed that potato clustered grouping was based on their characters and their origins. Keywords: genetic diversity, potatoes, RAPD

Abstract

Abstrak Tujuan penelitian ini mengkaji pengaruh zat pengatur tumbuh paklobutrazol (PBZ) terhadap kualitas bunga cengkeh (Syzygium aromaticum (L) Merr dan Perry). Perlakuan PBZ terdiri dari empat dosis, yaitu: 1). 0,0 g PBZ/phn/thn (kontrol), 2).  1,0 g PBZ/phn/thn, 3). 1,5 g PBZ/phn/thn, dan 4).  2,0 g PBZ/phn/thn. PBZ dilarutkan ke dalam 220 ml air mineral lalu disiram di tanah di bawah proyeksi tajuk tanaman. Hasil penelitian menunjukan bahwa PBZ mampu: 1)  meningkatkan ukuran panjang bunga dari 3,95% sampai 15,70%, 2) meningkatkan diameter bunga kering dari 6,52% sampai 14,58%, 3) meningkatkan jumlah bunga per tandan dari 4,91% sampai 72,50%, 4) meningkatkan berat cengkeh 1.000 butir bunga kering dari 10,28% sampai 23,88%, tetapi sesudah itu menurun menjadi  20,99%, 5) meningkatkan hasil bunga kering per pohon dari 37,22 % sampai 136,85 %. Secara keseluruhan, PBZ meningkatkan kualitas bunga cengkeh. Kata kunci: cengkeh (Syzygium aromaticum (L) Merr dan Perry), hasil, kualitas bunga, paklobutrazol (PBZ), Abstract The aim of this research was to evaluate the effect of growth hormone paclobutrazol (PBZ) on the flower quality of clove (Syzygium aromaticum (L) Merr and Perry). The treatment was the dosage of PBZ and consisted of 1) 0,0 g PBZ/tree/year (control), 2) 1,0 g PBZ/tree/year, 3) 1,5 g PBZ/tree/year, and 4) 2,0 g PBZ/tree/year. PBZ was diluted in 220 ml mineral water, then drenched to the soil next to the clove stem. The results showed that PBZ was able to enhance 1) the dry flower length as much as 3,95-15,70%. 2) the diameter of dry flower (6,52-14,58%), 3) the amount of flower per inflorescence  (4,91- 72,50%, 4) the weight of 1.000 dry flower (10,28-23,88%) followed by the decline of 20,99 %, 5) the yield per plant as much as  37,22-136,85 %. PBZ enhanced the quality of clove flower. Keywords: clove (Sysygium aromaticum (L) Merr dan Perry), flower quality, paclobutrazol (PBZ), yield.
