Abstract

This study aims to determine the effect of aluminum stress on rice varieties during the early vegetative phase using a nutrient culture medium. This research employs a completely randomized design with two treatment factors: rice varieties and aluminum concentration. The variety factor consists of Rindang 1, Situ Patenggang, Towuti, Inpago 8, Inpara, and Inpago 10, and the aluminum concentration is 0 ppm and 250 ppm. Rice seeds are germinated for three days. The seeds that have been germinated are then planted in Kimura B nutrient culture media. The condition of the planting media is Kimura B 100% and pH 5.5, and this is maintained until day 21 when the first sampling is conducted. Then, the solution is replaced with a new one using Kimura B 100% nutrient culture media and pH 3.5, along with the addition of 250 ppm aluminum, and this is done until day 28 when the second sampling is conducted. The same procedure is repeated until day 35 when the third sampling is conducted. The analysis results show that the application of 250 ppm aluminum stress significantly affects all rice varieties. In the variables of plant height and root length, the Rindang 1 variety has the highest average values, namely 178.17 cm and 92.12 cm, respectively. Meanwhile, for the variable of leaf count, the variety with the highest average value is Towuti, which is 28.60 leaves. Keyword: Aluminium, Nutrient Culture, Rice, Vegetative

Abstract

Penelitian ini mengkaji implementasi Sistem Manajemen Mutu ISO/IEC 17025 pada laboratorium diagnosa penyakit ikan di negara berkembang, dengan fokus pada tantangan dan strategi yang dihadapi. Melalui tinjauan literatur komprehensif, studi ini mengidentifikasi berbagai hambatan seperti keterbatasan sumber daya, infrastruktur yang tidak memadai, dan kurangnya keahlian teknis. Strategi yang diusulkan meliputi pengembangan kapasitas, kolaborasi internasional, dan adaptasi standar sesuai konteks lokal. Hasil penelitian menunjukkan bahwa meskipun implementasi ISO/IEC 17025 menghadapi tantangan signifikan, manfaatnya dalam meningkatkan kualitas dan reliabilitas layanan laboratorium sangat penting bagi perkembangan akuakultur dan keamanan pangan di negara berkembang.

Abstract

Penelitian ini mengkaji evaluasi kinerja dan tantangan manajemen laboratorium biosekuriti dalam konteks pencegahan zoonosis pada sistem peternakan terpadu. Melalui tinjauan literatur komprehensif, studi ini menganalisis praktik terkini, inovasi teknologi, dan pendekatan interdisipliner dalam manajemen laboratorium biosekuriti. Hasil menunjukkan bahwa integrasi sistem manajemen mutu, penggunaan teknologi informasi canggih, dan penerapan pendekatan One Health sangat penting dalam meningkatkan efektivitas pencegahan zoonosis. Tantangan utama meliputi keterbatasan sumber daya, kesenjangan teknologi informasi, dan kurangnya tenaga ahli. Penelitian ini menyoroti pentingnya kolaborasi lintas sektor, pelatihan berkelanjutan, dan standardisasi prosedur operasional untuk mengatasi tantangan tersebut. Temuan ini memberikan wawasan berharga bagi pengembangan strategi manajemen laboratorium biosekuriti yang lebih efektif dalam sistem peternakan terpadu.
