Abstract

Cogongrass is one of the top ten problem-causing weeds in the world that is invasively spread over many tropical and subtropical regions, including Java Island, the Republic of Indonesia. The wide distribution is possibly related to their adaptability to almost all terrestrial habitats from various altitudes, which may lead to a high level of genetic variation.  This study aimed to assess the genetic variation and phylogenetic relationship of cogongrass in Java Island using an intergenic spacer (IGS) sequence in the cpDNA genome, i.e. trnT(UGU)-trnL(UAA), as the molecular marker of high mutation rate. Plant samples were collected randomly from five different sites on the island. These were subjected to total genomic DNA extraction. The DNAs obtained were then used as PCR templates to amplify trnT(UGU)-trnL(UAA) IGS using a pair of universal primers. The PCR products were sequenced for genetic analysis. It was shown that an extremely high genetic variation with respect to the haplotype diversity of cogongrass in Java Island was observed. Nevertheless, a very low nucleotide diversity was obtained revealing a considerably close genetic relationship among the samples. Anatomical data regarding stomata number and length were found to correspond to the high level of genetic variation, but it was not the case with the stomata index.

Abstract

Bamboo is a versatile plant that has many benefits in the lives of the people of Gorontalo. This research aims to provide taxonomic information on bamboo species in Gorontalo Province, including variations in morphological characters and phenetic relationships of bamboo, as well as information on the traditional use of bamboo. The method used in this research is exploration and interviews. Exploration was carried out to collect information on bamboo taxonomy, while interviews were conducted to find out the use of bamboo by the Gorontalo Community. The research data obtained was then analyzed descriptively to describe and interpret data on morphological variations, phenetic relationships and traditional benefits of the various types of bamboo obtained. Based on the research results, it was obtained that 13 types of bamboo are distributed in Gorontalo which show the unique morphological variations of the varieties which are divided into four genera, namely the genus Gigantochloa has distinctive morphological characteristics on the waxy surface of the stem, the Bambusa genus with characteristic shiny, smooth stems, the Dendrocalamus genus has the largest diameter and stem wall thickness, the genus Schizostachyum has the same morphological characteristics of stem segments and branch lengths. Based on the analysis of phenetic relationships, two main clusters were formed with a similarity value of 61.2%. In terms of traditional uses, it was recorded in this research that most bamboo is used as building construction materials, food sources, traditional medicine, materials for traditional ceremonies, handicrafts, and ornamental plants, as a tool designedto help people's livelihoods and ecological functions. This research also provides the first record of the morphological characteristics and use of each type of bamboo in Gorontalo which can be used for future bamboo breeding and conservation projects.

Abstract

he increasing number of food needs is one of the driving factors for increasing agricultural production, but there are constraints on the availability of land. A polyculture system with corn, beans, and pumpkins, commonly known as the three sisters, can create positive interactions that can enhance the growth and development of each plant. This system has a vast potency to be applied to urban farming inside a grow bag because it does not require ample space, the placement of plants is flexible, and it produces a variety of yields. However, it is necessary to assess the effect of growing space on the growth of maize (Zea mays) cultivated by the three-sister system. This study used a completely randomized design with three treatments and six replications. The treatment consists of three planting spaces with various growing bags (treatment A:75 L, B:100 L, and C:200 L). The results of this study showed that the highest corn productivity was in the largest growing space (treatment C), which weighed 318.40 g/cob, and without husks 246.42 g/cob, but not significantly different from treatment B (grow bag 100 L), which weights 316.20 g/cob and without pods of 240.63 g/cob. This study found that the 100 L grow bag was the optimal growing space for planting corn in containers using the three sisters technique.

Abstract

Cayenne pepper is a leading horticultural commodity in Indonesia. However, the productivity and quality produced have not met market expectations. One of the contributing factors is the low quality of the soil. For this reason, switching from inorganic fertilizers to organic fertilizers, such as Black Soldier Fly Frass (BSFF), is necessary because it can provide several nutrients that are crucial in improving the soil's physical, chemical, and biological properties. In this study, the formulation of BSFF was tested for its impact on cayenne pepper's growth response and yield. The research was arranged in a completely randomized design consisting of three treatments with three repetitions, namely P1 (100 grams of BSFF biofertilizer), P2 (250 grams of BSFF biofertilizer), and P3 (500 grams of BSFF biofertilizer). The results showed an interaction between doses of  BSFF biofertilizer on plant height, physical conditions (color and size), number, and wet weight of cayenne pepper; which P3 gave the most optimal growth response and yield. In contrast to these results, all treatments reduced vitamin C  to the high level of N nutrients in BSFF biofertilizer. Therefore, further research is needed to find the right dosage (below 100 grams/500 grams of media) so that cayenne pepper has a high vitamin C.

Abstract

Obesity has a 15-fold higher risk of coronary heart disease, stroke, and diabetes mellitus. Microalga isone of the natural resources that potentially treat obesity. The purpose of this study was to evaluate the total phenolic contents (TPC), antioxidant, and anti-obesity properties of ethanolic extract of microalgae strain MRB-2. The TPC was determined using the Follin-Ciocalteu method. The antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, and the anti-obesity was analyzed using an anti-lipase pancreatic assay. The morphology of microalga cells was also determined using Scanning Electron Microscopy (SEM). The results revealed that the TPC of ethanolic extract from the ultrasound extraction method was higher than the maceration method with the value of 2.75±0.26 mg GAE/g. While the scavenging activity toward DPPH radicals of ethanolic extract from the maceration method was higher than ultrasound, with a value of 38.92±1.94% at 0.8 mg/mL. The lipase inhibitory activity of extract from the maceration method was higher than ultrasound with a value of 20.81±2.24% at 0.38 mg/mL. Our results indicate that ethanolic extract of MRB-2 was potentially developed for anti-obesity foods and health-functional foods derived from new peatland microalgae.

Abstract

The diversity of cassava in Wonosobo, Temanggung and Magelang districts must be investigated. The objective of the study was to analyze the diversity of cassava based on morphological characteristics. The cassava of each accession was planted in Bandongan, Magelang Regency. Morphological characters observed after six months of planting included apical leaf color, apical leaf hair, leaf lobe shape, petiole color, leaf color, number of leaf lobes, leaf length, leaf width, petiole length, vein color, petiole orientation, color epidermis of stem, color of outer appearance of stem, distance between nodes, stem growth, color of mature branch tip, branching type, tuber, tuber shape, outer tuber skin color, tuber flesh color, and tuber inner skin color. Analysis of the morphological characteristics of cassava is presented in the form of a dendrogram using the MVSP (Multi Variate Statistical Package) version 3.22. The results of the study obtained 39 accessions of cassava which showed different morphological characteristics. The lowest morphological similarity (0.735) was found in Group I only consisted of 2 acquisitions that did not have tubers, namely Red Vegetables and Green Vegetables and Group II ( Groups III and IV) have a similarity of 0.92. The highest similarity was in groups IIIa and IIIb and Groups IVa and IVb have a similarity coefficient value of 0.95. The morphological diversity of 39 accessions is a source of cassava germplasm: 37 accessions are harvested for tubers and 2 accessions areharvested explicitly for leaves as vegetables. This research was useful for the development of cassava-based food industry bioproducts.

Abstract

Cardamom (Amomum compactum) is an aromatic spice plant with numerous benefits, widely used in cooking, medicine, and beverages. The high demand for cardamom remains unmet due to the lengthy germination period required for cardamom seeds and the inability of cardamom shoots to thrive when planted independently from the mother plant. The presence of the mother plant significantly impacts cardamom nurseries utilizing shoots, making it challenging to obtain large quantities of nursery transplants. Growth stimulants, such as vitamin B1 and Indole Butyric Acid (IBA), are required to en­hance vegetative growth in plants. Vitamin B1 (IPI brand) is applied due to its ease of accessibility and cost-effectiveness. Meanwhile, IBA is utilized for its accessibility, stable chemical content, and prolonged efficacy. This research aims to determine the optimal concentration of vitamin B1, IBA, and their combination to enhance the growth of mother and tiller shoots of cardamom ex vitro. The research employed a two-factorial Randomized Complete Block Design, with vitamin B1 concentrations of 21.5% and 43% and IBA concentrations of 0.75 ppm and 150 ppm. The treatment V1I1 (vitamin B1 21.5% and IBA 75 ppm) on mother plant shoots maintained a survival rate of 67% up to 12 Weeks After Planting (WAP). The interaction between vitamins B1 and IBA exhibited no significant effect on all parameters of mother shoots and tillers; however, vitamin B1 significantly influenced the vegetative growth of cardamom mother shoots. Vitamin B1 at 43% produced a significantly higher number of leaves compared to 21.5%. Thus, vitamin B1 at 43% is recommended for cardamom propagation, while vitamin B1 at 21.5% has the potential to enhance the average growth of tiller shoots across all parameters.

Abstract

The existence of undergrowth has an important role as an ecosystem both from an ecological and economic perspective. However, the composition and diversity of undergrowth in an area depends on the land use system. This research aimed to know the species composition and diversity of undergrowth at forest garden stands. Data collection was carried out with a vegetation survey using nested rectangular plots with a sampling intensity of 1%. The data collected included undergrowth species, the number of individuals for each species, and tree species as components of forest garden stands. Data were analyzed by calculating density, frequency, important value index, and Shannon diversity index. The results showed that the undergrowth that exists under forest garden stands were 38 species dominated by 12 species, namely Acalypha australis, Asystasia gangetica, Clidemia hirta, Starchytarpeta jamaicensis, Mikania micrantha, Peperomia pellucidia, Setaria barbata, Andropogon aciculatus, Alpinia galanga, Diplazium esculentum, Paederia foetida, and Crassocephalum crepidioides. The forest garden stands were composed of 43 tree species dominated by 4 tree species, namely Durio zibethinus, Aleurites moluccana, Myristica fragrans, and Gnetum gnemon. The level of undergrowth diversity was in the medium category with an H value of 1.540, indicating the diverse of undergrowth species.

Abstract

Food and feeding habits are important things in bioecological of fish. This study provides an understanding of the feeding habits and intensity of the M. gulio, by analyzing its food composition, relative gut length (RGL) and gastro-somatic index (GaSI). Fish specimens were caught with a gill net and fishing rod in an area of Cianjur estuaries during a period of one year from October 2021 to September 2022. The analysis of 452 fish samples shows that the relative gut length (RGL) values revealed the feeding habit of M. gulio as carni-omnivorous. The GaSI value was used to determine feeding intensity and was found to be highest in November, at Cidamar estuary, and in the second size group (7.1-10 cm). These results provide new knowledge on this fish species’ feeding habit and intensity, which also helps understand the fish adaptation and conservation in the study area.
