Abstract

Non-Timber Forest Products (NTFPs) are a part of forest ecosystem which have various roles, both in the natural environment and in human life. The NTFPs usually used as the basis for alternative economic value of a forest, and the demand for NTFPs are related to forest management. Plants are often  used as NTFPs, and the highest demand of the products is handicraft that are bought and sold across economic centers, but the detail information about the NTFPs and their derivative products in those capital areas are less known. This research investigates the use of NTFPs for craft products in Padang Panjang City, West Sumatra, Data on plant species, the derivate craft products, the part of plant used, sizes, water content, the demand for raw material for each product, place of origin, and the prices were colleted directly to all three existing craft shops in Padang Panjang City. Four plant species were found for making 17 types of craft products, namely bamboo (Bambusa spp.), rattan (Calamus spp.), coconut (Cocos nucifera L.), and pandan (Pandanus spp.). The most craft products was made from rattan, and the most part of plants used was the stem, which less than 30 mm in size, and below 14% in water content. Coconut and Pandan was found as fruit and leaves. Only two of 17 products were made locally in Padang Panjang.  The results of this research show that rattan as a type of NTFPs that mostly commercialized for craft products in Padang Panjang City. This data can be used for communities living at forest adjacent around Padang Panjang City on extracting the NTFPs.

Abstract

The agricultural sector cannot be separated from the role of inorganic fertilizers to support plant growth, as is the case with rice cultivation. Farmers' dependence on using inorganic fertilizers has led to decreased soil fertility and damage to natural resources. One way to overcome this is to implement organic farming. Organic cultivation in this research uses the SRI (System of Rice Intensification) method, while inorganic cultivation follows conventional methods from local communities. The aim of the research was to determine the effect of giving Trichoderma asperellum on rice plant height in organic and inorganic cultivation. The research was carried out in September-December 2022 in Jorong Galo gandang, Nagari III Koto, Tanah Datar Regency, Biological Research Laboratory, and Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State University. This type of research is experimental. The research was structured using a Randomized Block Design, with 4 treatments, namely; O (Organic) OT (Organic + Trichoderma asperellum), A (Inorganic), AT (Inorganic + Trichoderma asperellum) and 5 repetitions. Observational data was analyzed by analysis of variance (ANOVA) using the SPSS application. If there are differences, continue with the DNMRT test (Duncan's New Multiple Range Test). The results showed that giving Trichoderma asperellum had no significant effect on rice plant height in organic and inorganic cultivation. Because the high rainfall at the research location caused the nutrients from each experimental plot to be washed away by the water.

Abstract

Pterocarpus indicus Willd. also known as redwood is a native Philippine species belonging to the Fabaceae family that has many uses and high economic value and highly exploited. However, it is not accompanied by good regeneration which causes this species to be categorized as endangered (IUCN v. 2021-1). The in vitro technique is an alternative to overcome this problem. This study aims to determine the response of P. indicus Willd. shoot growth to the addition of BAP and TDZ in vitro. The research was conducted from August to December 2023, at the Biotechnology Laboratory, KST BJ. Habibie Puspiptek Serpong, South Tangerang, Banten. This study used a completely randomized design (CRD) consisting of 9 treatments and 14 replications. The treatments consisted of: R0 = Control, R1 = BAP 0,25 ppm, R2 = BAP 0,5 ppm, R3 = BAP 0,75 ppm, R4 = BAP 1 ppm, R5 = TDZ 0,25 ppm, R6 = TDZ 0,5 ppm, R7 = TDZ 0,75 ppm, R8 = TDZ 1 ppm. The results showed that the concentration of BAP 0,5 ppm gave the best results in height of shoot and TDZ 0,25 ppm gave optimum results in the number of shoots compared to the control and other treatment concentrations.

Abstract

Weeds are plants that humans try to manage because they inhibit the growth of cultivated plants or are harmful to human interests. This study aims to evaluate the effect of teki grass extract (Cyperus rotundus) on the growth of green beans (Vigna radiata) and red spinach (Amaranthus dubius). The research method used a completely randomized design (CRD) with two extract concentration treatments (30% and 50%) applied to both plants. The results showed that treatment with teki extract significantly affected plant growth, with a decrease in height and fresh weight at higher concentrations. The allelopathic effect of the teki extract inhibited the vegetative growth of mung beans and red spinach, indicating that this extract has potential as a bioherbicide agent.
