Abstract

Penelitian bertujuan untuk mengkaji pengaruh jumlah ruas stek dan sumber pupuk nitrogen yang berbeda pada pertumbuhan dan produksi simplisia tanaman Kumis Kucing(Orthosiphon aristatus). Rancangan percobaan yang digunakan adalah rancangan acak lengkap pola faktorial. Faktor pertama adalah jumlah ruas batang stek (3, 5, dan 7 ruas) dan faktor kedua adalah sumber pupuk nitrogen (urea, pupuk kandang ayam, pupuk kandang sapi, dan pupuk kandang kambing). Parameter pertumbuhan yang diamati meliputi panjang tunas total, jumlah daun, dan volume akar. Parameter produksi yang diamati yaitu berat daun (simplisia) segar dan kering. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji berganda Duncan (Duncan’s Multiple Range Test). Hasil penelitian menunjukkan peningkatan jumlah ruas stek mampu meningkatkan panjang tunas total, jumlah daun, dan volume akar. Penggunaan sumber hara nitrogen yang berbeda hanya meningkatkan parameter volume akar. Kedua perlakuan belum mampu meningkatkan produksi simplisia tanaman kumis kucing, serta tidak menunjukkan adanya interaksi pada seluruh parameter penelitian. Kata kunci : Orthosiphon aristatus, Simplisia, Stek, Sumber Nitrogen.

Abstract

Setting the temperature of the storage space of seeds and storage containers will greatly affect the quality of the seed. The aim of this research was to study the effect of temperature treatment, storage container and their interaction on seed quality and seedling growth of chilli. The study was conducted in Jetis Village and Laboratory of Plant Physiology and Breeding, Faculty of Animal and Agricultural Sciences, Diponegoro University from January to June 2017. The study was conducted using nesting experiments on the basis of Completely Randomized Design (RAL). The first factor was Storage Temperature (R1 = Room Temperature 24-29 oC, R2 = Refrigerator Temperature 5oC) and second factor was storage container nested at storage temperature that was (P1 = Alumunium foil, P2 = Paper and P3 = Plastic). Each treatment had 5 replications and each replication consisted of 100 seeds, so there were 30 experimental units. The data were analyzed by using analysis of variance (ANOVA) and continued with test of HSD (Honesty Significant Difference) 5% significance level. The results showed that the storage temperature (5oC) temperature increased the temperature and the seed vigor index was larger than the room temperature (28oC), the aluminum foil packaging produced the maximum growth potential and germination rate was higher than the plastic and paper packaging but there was no different growth rate and index vigor. Low storage space temperatures (5oC) can not maintain maximum seed quality where the 4 parameters were still below the standard quality of the seed. Seeds stored in low temperature (5oC) rooms producedfresh weight and dry weight of seedlings larger than high temperature (28oC), but the number of leaves, seed height and hypothetical vigor index were not significantly different. The aluminum foil packaging producedfresh weight and dry weight of seeds higher than plastic and paper packaging. However, the number of leaves, the height of seed and the hypothetical vigor index were notsignificantly different. Keywords : Temperature, container store, seeds quality, seedling growth, chilli.

Abstract

[EFFECT OF CONCENTRATION AND TIME INTERVAL OF BABANDOTAN BIOPESTICIDE SPRAYING ON THE INTENSITY OF DAMAGE AND YIELD OF KAILAN]. Biopesticides from Ageratum conyzoides plants are used as an alternative in pest control. The used of synthetic pesticides was widespread as an effort in pest and disease control because it worked effectively and quickly, but caused resistance and resurgence of pests were bad impact on the environment for long term. The content of active compounds in Ageratum conyzoides plants such as flavonoids, anthraquinone, tannins, terpenes, phenols, saponins, alkaloids and steroids worked as controllers of various cultivated plant pests. This study aims to determine the spraying concentration and interval of spraying Ageratum conyzoides on the intensity of damage and yield of kailan plants. This research was conducted in November 2020 - January 2021 at Agroecotechnopark research land, Diponegoro University, Semarang. The experimental design used was a factorial Randomized Complete Block Design with 3 replications. The first factor was spraying concentration (10%, 30% and 50%) and the second factor was interval of spraying (once every 5 days, 10 days and 15 days). The variables observed were absolute damage rate, relative damage rate, plant height, number of leaves and fresh weight of kailan. Data were analyzed by Analysis of Variance followed by DMRT (Duncan's Multiple Range Test). The results showed that Ageratum conyzoides biopesticide was able to control pests and and to support kailan growth. Spraying babandotan biopesticide at a concentration of 50% has been able to reduce the rate of crop damage by pests, supported vegetative growth, and increased kailan growth to provide optimal yield. Spraying time interval did not affect all variables.
