Abstract

Silica protects plants from abiotic stress. Planting media provides a place to grow and nutrition for plant growth. The research aims to study the effect of bamboo leaf silica dosage and growing media on the yield of red beets cultivated in the lowlands. The research was designed using a completely randomized factorial design (CRD) with two treatment factors. The first factor is the dose of bamboo leaf silica fertilizer (0 ppm, 0.15 ppm, 0.30 ppm, 0.45 ppm, 0.60 ppm). The second factor is the growing media (soil growing media; soil growing media + goat manure, and soil growing media + goat manure + husk charcoal). Research results: bamboo leaf silica dosage (0.3 ppm, 0.45 ppm and 0.60 ppm) affects the chlorophyll b and total chlorophyll. Growing media soil + goat manure + husk charcoal affects the length of red beet plants, number of leaves, diameter and length of red beetroots, wet weight and dry weight of red beetroots. Combination of growing media treatment (soil + goat manure + husk charcoal) with all doses of bamboo leaf silica increased the chlorophyll a, chlorophyll b and total chlorophyll. The sugar content of red beetroots was not influenced by the dose of bamboo leaf silica or the growing medium. Keywords: Chlorophyll, Husk Charcoal, Manure, Soil.

Abstract

This study investigates the effect of temperature and nitrogen doping (N-Doping) on the pyrolysis of bamboo waste to optimize the distribution of biochar, bio-oil, and gas products. Bamboo waste as raw material was applied to pyrolysis in a quartz tube furnace reactor at temperatures of 300°C, 400°C, 500°C, and 600°C under two atmospheric conditions: pyrolysis with nitrogen (PN) and pyrolysis without nitrogen (PWN). Results reveal that temperature significantly influences product distribution, with bio-oil yield peaking at 500°C (52% in PN) and decreasing at higher temperatures due to secondary cracking. Nitrogen doping enhances bio-oil production by preventing oxidation and reducing secondary reactions, leading to a bio-oil yield increase from 16.52% in PWN to 55.32% in PN at 500°C. Conversely, PWN conditions resulted in higher biochar yield due to partial oxidation. Gas yield increased at elevated temperatures in both conditions, attributed to thermal cracking and reformation processes. These findings emphasize the importance of controlled temperature and atmospheric conditions in maximizing the efficiency and product quality of bamboo waste pyrolysis. The results provide valuable insights into sustainable biomass conversion strategies, contributing to renewable energy development and bamboo waste valorization.

Abstract

Morphological characters are basic characters to identify rice cultivars. The information of glutinous rice cultivars in Ponorogo is still very limited, therefore the exploration and characterization of the local cultivar are needed. The research aimed to explore and identify local cultivars based on morphological characters of plant, grain, and milled rice. The research was conducted on March-October 2018 at elevens subdistricts in Ponorogo. There were eleven cultivars have been collected and characterized, namely five white glutinous rice cultivars (Latisa, Tawon, Semok, Pelem, Genjah), three red glutinous rice cultivars (Garingan, Merah Pendek, Jowo), and three black glutinous rice cultivars (Wilis, Gundik, dan Gontor Bulu). The eleven cultivars were varied on plant height, panicle length, flowering time, number of tillers, grain size and shape, and the color of aleurone. The analysis of diversity and similarity on characters showed that all cultivars could be classified into four different groups. The first group was Latisa (Gontor Bulu), the second was Tawon group (Pelem), third was Genjah group (Garingan, Merah Pendek and Jowo), and the fourth was Wilis group (Gundik). Keywords: aleurone , diversity, exploration, rice grain, similarity
