The shrinkage of wood and the dimensions of wood fibers in the radial positions of stem are two important factors in the use of wood. An understanding of the dimension of wood fiber and the shrunkage of the wood in the radial direction can guide the optimum use of timber. The purpose of this study is to determine the shrinkage and changes in the dimensions of the timber (Combretocarpus rotundatus Dans) in the radial direction. The method used refers to the British and IAWA standards. The parameters measured are the radial and tangential shrinkage of wood as well as the dimensions of the fiber. The t test is used to test statistically. The results obtained showed that the position in the radial direction of the stem had a significant influence on the tangential shrinkage of fresh-oven dry and the fiber dimensions of Tumeh wood. The tangential shrinkage of the near pith is lower than that near the bark. The nearest pith part has a shorter fiber length; a thicker fiber wall is thinner than the near bark but still in the same quality class (Grade III)

Most farmers typically plant rice only once a year, leading to weed-infested fields. Using aquatic weeds as Pupuk Organik Padat (POP) is seen as a viable approach to weed control. This study aims to explore the interaction and effects of different types and doses of aquatic weeds as POP and identify the most effective combination. The research was conducted in Banua Budi Village, Barabai District, Hulu Sungai Tengah Regency, from June to October 2023, utilizing a Randomized Complete Block Design (RAK) with 2 factors, grouped based on tuber diameter. The types of POP (J) include three levels: j1: POP water mimosa, j2: POP lotus, j3: POP banto grass. The POP dosage factor consists of two levels: d1: 20 ton.ha^-1 equivalent to 2 kg/plot, d2: 30 ton.ha^-1 equivalent to 3 kg/plot. There were six combinations with four replications, resulting in 24 experimental units. Each experimental unit comprised 16 plants, and four sample plants were observed, making a total of 96 sample plants. The findings indicate that the interaction and individual treatment types had no significant impact on the observed variables. However, when considering the single treatment of water weed with POP dosage, there was a notable effect. The optimal dosage was found to be d₂: 30 ton.ha^-1 or equivalent to 3 kg/plot.
