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

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

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.

Abstract

Ferns of Ophioglossaceae and Psilotaceae families can be found in the "Eka Karya" Botanical Garden, Bali as a collection or naturally growing in the botanical garden and those families are taxonomically classified as primitive ferns. The morphological characteristics of the family of Ophioglossaceae and Psilotaceae or even other types of ferns can be known through the morphological characteristics of the spores. This study aimed to characterize the spore morphology of the Ophioglossaceae and Psilotaceae fern of The "Eka Karya" Botanical Garden. Observation of the morphological characteristics of spores in the "Eka Karya" Botanical Garden was carried out by a simple method without acetolysis. The result of six types of fern plants from the family of Ophioglossaceae and Psilotaceae showed similarities to the spore unit, monads. Each family has unique characteristics that can be used to differentiate each other. The family Ophioglossaceae has a variety of spore colors, trilete spore types, mostly globose-shaped (except for one species the trilobate), the average polar diameter is 28.59±2.19 – 31.00±2.49 μm and the equatorial diameter is 32.85±1.74 – 37.55± 1.71 μm, the P/E ratio is 0.79-0.87, the shape based on the P/E ratio is suboblate, the spore size category is medium and has radial symmetry. For the family Psilotaceae, has a pale yellow-green spore color, monolete type, elongate-ellipsoidal shape, average polar diameter of 26.20±2.76 –29.81±2.96 μm and equatorial diameter of 52.98±2.55 – 63.31±4.65 μm, P/E ratio of 0.47-0.49, shape based on P/E ratio i.e. peroblate, large spore size category and has bilateral symmetry. Those characteristics are valuable taxonomic data that can be used as diagnostic characters for the identification of the families Ophioglossaceae and Psilotaceae.

Abstract

Lactobacillus plantarum BP102 isolated from garlic bulb tissue has probiotic properties, including producing bacteriocin called plantaricin. This study aimed to detect the gene encoding bacteriocin produced by Lactobacillus plantarum BP102, and to evaluate the bacteriocin activity at each stage of partial purification. After the end of the log phase of L. plantarum BP102 was determined, and the bacteriocin-encoding genes were checked by PCR technique. Partial purification of bacteriocin was elucidated including pH-neutralized cell-free-supernatant (CFS), precipitation using 80% of ammonium sulfate, and dialysis (cut-off 10 kDa), then the bacteriocin activity in every partial purification stage was evaluated. The molecular weight of plantaricin was estimated using SDS-PAGE analysis. Lactobacillus plantarum BP102 harbored the gene encoding plantaricin (pln) biosynthesis, namely plnEF and plnK genes. The activity of crude bacteriocin was inactivated by the presence of proteinase-K enzyme. The protein concentration was gradually decreased along with the purification process. The bacteriocin activity was demonstrated at each step of the purification process (CFS, precipitation, and dialysis) against Bacillus cereus by 9.23 ± 0.20 mm, 7.86 ± 0.15 mm, and 7.6 ± 0.10 mm, respectively; while, Escherichia coli by 10.3 ± 0.55 mm, 7.4 ± 0.1 mm, and 6.86 ± 0.45, respectively. The molecular weight of partially purified bacteriocin BP102 was found to be approximately 15.9 kDa. The overlaid part of the gel showed a slight inhibition against E. coli due to a low protein concentration. This bacteriocin purification process should be further optimized to improve the bacteriocin activity that could be useful for food preservation.

Abstract

Pteridophytes (ferns) are a fundamental element of tropical rainforests, which provide excellent microhabitats for their development. In addition, the sensitivity of pteridophytes to shifts in microclimate and anthropogenic disturbances makes them excellent environmental bioindicators. The purpose of this study was to determine the diversity and distribution of pteridophytes along the elevational gradient of two well-known hiking trails of Mount Penanggungan, East Java, Indonesia. Using a 10x10 m2 plot and transect line, we examined the composition, species diversity using Shannon-Wiener diversity index (H'), relative abundance, and distribution pattern using Morisita index of dispersion (Id) of ferns along an elevational gradient (700–1500 m above sea level) on the hiking trails of Mount Penanggungan, i.e., Tamiajeng and Kunjorowesi. As many as 14 species from 7 families living in both terrestrial and arboreal types were identified. Species composition along the elevation gradient revealed a pattern of predominating species. The Shannon-Wiener diversity index (H') indicated a moderate level of diversity, where many pteridophytes species are found on the altitude gradient between (700-900 m dpl), and the Morisita index of dispersion (Id) indicated a clustered distribution pattern for most of the species. This pattern of diversity and distribution can be explained by changes in biotic and abiotic factors.

Abstract

Sorghum is a strategic commodity with good nutritional and high antioxidant content that can be used as a source of food, feed, and industrial raw materials. Sorghum is a relatively low and less intensive crop than other staple food crops. Sorghum yield can be increased by establishing plant population through a mulching planting system. The purpose of this study was to determine the yield power of several sorghum genotypes, namely three new superior varieties (Bioguma, Kawali, and Samurai) and three local varieties (Plonco, Hitam Wareng, and Ketan Merah), planted with a plastic mulch planting system. The research was conducted on farmers' land in Karangmojo, Gunungkidul, Daerah Istimewa Yogyakarta, which is a dryland soil type. The experimental design used a randomized complete block design (RCBD) with 5 replications. Observation parameters included growth components and sorghum production. The results showed that sorghum planting with a mulching planting system was able to provide yields for the Bioguma variety of 7.70 tons/ha, Plonco variety of 8.41 tons/ha, Samurai variety of 5.38 tons/ha, Kawali variety of 8.21 tons/ha, Hitam Wareng variety of 3.91 tons/ha, and Ketan Merah variety of 4.00 tons/ha. Based on the results of the study, it was found that the genotypes of local varieties were able to compete with new superior varieties and had the best growth response and yield power in the rainy season planting.
