Abstract

DOWNLOAD PDFDalam tulisan ini, diperkenalkan dua klas khusus dari ring  yaitu Ring Noetherian dan Ring  Artinian.  Berawal  dari  adanya  suatu  ring  komutatif  yang  mempunyai  suatu  ideal (ideal  kiri  dan  ideal  kanan).  Apabila  ideal  tersebut  memenuhi  kondisi  rangkaian  naik (ascending  chain  condition/ACC)  maka  terbentuklah  klas  yang  dikenal  sebagai  ring Noetherian dan apabila ideal tersebut memenuhi kondisi rangkain turun (descending chain condition/DCC)  maka  terbentuklah  klas  yang  dikenal  sebagai  ring  Artinian.  Selanjutnya dipaparkan  pula  definisi  dan  contoh  dari  ring  Noetherian  dan  ring  Artinian.  Selain  itu, diberikan  teorema  yang  menjelaskan  keadaaan  dari  ring  pembagi  pada  suatu  ring Noetherian.Kata kunci : Ring Komutatif, Kondisi Rangkaian Naik Dan Turun, Bebas Linear.

Abstract

Acacia mangium is one of the favorite types of plants in HTI, but in its growth often occurs root rot disease. Ganoderma sp. is one of the root causes of root rot disease. Control can use biological agents such as Trichoderma local isolates. This study aims to determine the power of antagonists and get the best local Trichoderma isolates to control root rot by Ganoderma with in vitro method. The research was conducted at Silviculture Laboratory of Faculty of Forestry, Tanjungpura University for 4 months. The method used is an experimental method. Consists of isolation and characterization of isolates Ganoderma sp. And Trichoderma spp. antagonist test against Ganoderma sp. local isolate Trichoderma spp. consists of 4 treatments namely Trichoderma sp1 (T1), Trichoderma sp2 (T2), Trichoderma sp3 (T3), Trichoderma sp4 (T4). Each treatment was placed in conjunction with Ganoderma sp. On top of the PDA. An antagonistic test was performed with a completely Randmized Design pattern. Each treatment was repeated 3 times so that there were 15 experimental units. The result of the antagonistic inhibitory test of Trichoderma sp. Against Ganoderma sp.  Shows a different percentage of inhibition. The percentage of inhibition on T1 treatment was 58.06%, T2 was 43.80%, T3 was 48.11% and T4 was 38.09%. The result of variance analysis showed the treatment of isolate Trichoderma spp. Has no significant effect on inhibiting root rot disease pathogen caused by Ganoderma sp. Keywords: Acacia mangium, Ganoderma sp., In Vitro, Trichoderma spp.

Penelitian ini bertujuan untuk mengetahui motivasi para peserta dalam mengembangkan keterampilan menjahit pakaian, kendala ibu-ibu dalam mengembangkan keterampilan menjahit pakaian dan mengetahui dampak setelah mengikuti pelatihan menjahit terhadap peserta. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kuantitatif. Data penelitian ini bersumber dari ketua pelaksanaan pelatihan dan peserta yang telah mengikuti pelatihan pada tahun 2013 di Desa Lamgeu Baro berjumlah 40 peserta, pengumpulan data menggunakan observasi, wawancara dan kuesioner. Pengolahan data yang dilakukan dalam penelitian ini menggunakan rumus persentase. Hasil penelitian pada umumnya mengikuti pelatihan menjahit mendapatkan motivasi dari keluarga. Kendala mengembangkan usaha menjahit karena hanya sedikit sekali mempunyai pengetahuan dalam menjahit. Dampak terhadap responden selesai mengikuti pelatihan mendapatkan pengetahuan dan pengalaman dalam menjahit. Simpulan penelitian ini adalah untuk peserta dapat memanfaatkan ilmu keterampilan menjahit dalam mengembangkan usaha menjahit supaya dapat membantu perekonomian keluarga, dan pihak PNPM-MP selaku pihak penyelenggara pelatihan menjahit untuk melakukan evaluasi kembali terhadap desa-desa yang telah di adakan pelatihan.

Abstract

The community of Alue Ie Puteh Village is a group of people who live in the coastal areas and has problem with the availability of clean water. The lack of water treatment technology becomes an obstacle for the community in water treatment. The objective of this activity is to provide knowledge or understanding to the community about the utilization of activated carbon from coconut shell as filter media in gravity-fed filtering system. The activity was carried out for 3 months from June?August 2017 and consists of several steps: 1) Socialization; 2) Training; and 3) Monitoring and evaluation. The results show that people in the Village of Alue Ie Puteh have been able to apply technique of producing the activated carbon from coconut shell as filter media in gravity-fed filtering system.
