Abstract

Graymold is one of devastating fungal disease of castor plants (Ricinus communis L.) caused by Botryotinia ricini. Resistant germplasm is the basic and essential sources to support castor breeding obtaining disease resistant varieties. Objective of this study was to identify castor genotypes resistant to gray mold in peatland agroforestry area in Kepulauan Meranti that naturally infected by graymold fungal pathogen.  This is the first report about castor plants cultivated under peat soil. Infected and uninfected castor plants were sampled and analyzed their Resistance Gene Analog (RGA).  Results showed that resistant plants expressed diverse phenotype and amplified DNA fragment using RGA primers. The fragments were similar to ABC transporter gene which is one of RGA classes. Additionally, the fragments revealed P-loop NTPase conserved domain. In contrast, all infected plants failed to produced PCR product.  The results indicated that uninfected castor plants can be used as source of resistant trait. Their RGA sequences can be analyzed to develop molecular marker for supporting gray mold resistant breeding program.

Abstract

Organogenesis is regeneration mechanism on the process of organ formation derived from somatic or non-meristematic tissue on in vitro technique. Organogenesis can occur directly or indirectly. This research used porang leaves as explant, and medium MS Basal with addition such as sucrose, agar, combination of PGR’s 2,4 D and NAA, and aquadest. This research method used the Completely Randomize Design (CRD) with 9 different level combination of 2,4 D and NAA such as 2,0 ppm 2,4 D + 1,5 ppm NAA (A1), 2,0 ppm 2,4 D + 2,0 ppm NAA (A2), 2,0 ppm 2,4 D + 2,5 ppm NAA (A3), 2,5 ppm 2,4 D + 1,5 ppm NAA (A4), 2,5 ppm 2,4 D + 2,0 ppm NAA (A5), 2,5 ppm 2,4 D + 2,5 ppm NAA (A6), 3,0 ppm 2,4 D + 1,5 ppm NAA (A7), 3,0 ppm + 2,0 ppm NAA (A8), 3,0 ppm 2,4 D + 2,5 ppm NAA (A9) with 3 repetitions for each combination. Quantitative data such as the percentage of explants that appeared callus and roots were tested statistically by using ANOVA to determine the significance of the effect of the treatment. Treatments that had significant results were then tested using the DMRT test with a level of α=5%. Qualitative data were observed visually and analyzed descriptively. Combination concentration treatment of 2,4 D and NAA have the significant effect on callus and root formation. The level of 2 ppm 2,4 D and 2 ppm NAA is the best treatment on callus formation process in terms of 100% callus emerge and the early day appears at 24 days after planting and the best treatment on the process of root formation in terms of percentage roots emerge 100% and the early day roots appears at 46 days after planting. Indirect organogenesis is type of of root regeneration.

Abstract

Diabetic wounds are a serious problem and need to be treated appropriately. One of the wound healing efforts is using the leaves of the Averrhoa billimbi (Abl). This study aims to examine the reduction in wound healing and histopathological images of wound-healing rats with Abl extract. The rat in the study were 2-3 months old, weighed 200-250 grams and were 12 male. The rat were divided into 3 groups: the control group (G1) received only distilled water, the group 10 µl extract (G2) and the group of diabetic mice received 10 l extract (G3). The treatment and skin tissue samples were obtained on day 8. The rats were digested with ether solution and skin incisions were made, followed by povidine idone administration. The study data were analyzed by analysis of variance (ANOVA). Statistical test results showed that the incision reduction was highest in G2, followed by G3 and G1 at 1.120 ± 0.156, 1.405 ± 0.007, 1.510 ± 0.028, respectively. Histopathological images of proliferative fibroblast cell counts and collagen density were higher in K3 than in K1. Based on the study results, it can be concluded that using 10 µl extract can heal cuts in diabetic rats.

Abstract

Moss plants can live well in areas that have high humidity. The Dutch Guesthouse which is located in the Sultan Adam Mandiangin Forest Park area has high humidity because the area has lots of dense plants, so it is a suitable habitat for the living nature of moss plants. This study aims to describe and identify the various species of moss found in the area of study. Data collection was carried out using the exploring method, followed by determining and identifying each sample of the moss plants found in the laboratory. Data analysis was carried out descriptively and identifying species with reference to the relevant literatures. The results found 10 species of mosses belonging to 7 different families, both found in tree, rock and soil habitats. The species found were: Calymperes tenerum, Calymperes afzelii, Hyophila apiculata, Hyophila involuta, Ectropothecium falciforme, Octoblepharum albidum, Philonotis hastata, Acroporium secundum, Lejeunea lamacerina, and Thysananthus sp. The results of this study are expected to provide information about the variety and biodiversity of mosses in South Kalimantan.

Abstract

Stenochlaena palustris, commonly known as pakisan weed, poses significant challenges in oil palm plantations due to its highly invasive nature, which can lead to reduced agricultural productivity. Management of this weed is critical, as effective control measures can inhibit its dominance and promote the proliferation of alternative weed species, thereby enhancing biodiversity within the ecosystem. This study aimed to 1) assess the effectiveness of the herbicide ammonium glufosinate, in combination with an adjuvant, for controlling S. palustris in oil palm plantations, and 2) investigate the subsequent alterations in the weed community structure following herbicide application. We employed a randomised group design (RAK), incorporating the herbicide with added adjuvants. Results showed a clear change from S. palustris to Asystasia sp. as the dominant species. Treatments K and H had the most Asystasia sp., while treatment L had the least. Furthermore, we clearly compared treatments L, K, and S to the control treatment, emphasizing the emergence of diverse species within the treatment plots. However, low levels of diversity and evenness suggest a stressed weed community, indicating that the herbicide application can disrupt existing ecological balances. This study emphasizes the importance of assessing herbicide impacts not only on targeted weed species but also on broader community dynamics, revealing a significant research gap in understanding the long-term ecological consequences of herbicide use in oil palm plantations.

Abstract

The use of pesticides is one of the control alternatives that is widely used by farmers. However, continuous and inappropriate use of pesticides can have negative impacts on humans and the environment. This research aims to determine the relationship between the level of farmer compliance in using pesticides and pest attacks, disease, natural enemy populations and product safety. The research was conducted in two areas, namely Tanjung Lago and Pemulutan by interviewing farmers and direct observation of rice fields. The variables observed were the percentage and intensity of pest attacks, plant disease. and natural enemy populations. The level of farmer compliance is connected to field data and the correlation efficiency is calculated. The relationship between farmer compliance in the use of pesticides against pests and disease is negatively correlated, and positively correlated with the population of natural enemies.  Using herbal pesticides according to the dosage can reduce the negative impact of pesticides on the environment.

Abstract

Mangrove in Citeureup Village, Panimbang District, Pandeglang Regency is a mangrove area that is located at the western coastal of Java Island. Panimbang District is one of areas in Pandeglang District where abrasion occurs. Almost half of the shoreline having damaged that is caused by abrasion. In 2010, the damaged mangrove area in Panimbang District was 37.07 ha wide. Meanwhile, for the mangrove area in Citeureup Village, still no data available that specifically defines the condition of that area. Hence, the study about analytical approach of mangrove vegetation for knowing the mangrove health in that area is needed to be done. The sample retrieval was located in Citeureup Village, Panimbang District, Pandeglang Regency. The method of mangrove health evaluation integrating vegetation analysis and canopy cover quantification, the location determination was determined by purposive sampling. The result of this study showed that the mangrove ecosystem condition  in Citeureup Village, Pandeglang Regency, Banten Province was in a good condition since it has the average value of  >1,500 ind/ha in every station. The mangrove composition was dominated by the species of A. marina and A. alba. A. marina species was dominating all of the research area. The structure of mangrove vegetation had the mangrove density with tree category was around 2,350-5,167 ind/ha, this condition showed that it was in a good category. The percentage of canopy cover was categorized as moderate to dense with 51.95-93.18%. The percentage value of canopy cover is affected by the mangrove density and the dominating species.
