Abstract

The Damahu waxy corn (Zea mays L. var. Damahu) is a local variety traditionally cultivated by the Gorontalo community and possesses significant potential for the development of functional food products. This study aimed to determine the nutritional composition of the Damahu waxy corn variety originating from Bontula Village, Asparaga District, Gorontalo Regency, through proximate analysis. The corn samples were dried, milled, and analyzed using standard analytical procedures to quantify moisture, ash, fat, protein, and carbohydrate contents. The results indicated that Damahu waxy corn flour contained 83.32% carbohydrates, 5.93% protein, 1.67% fat, 8.84% moisture, and 0.24% ash. This composition characterizes the Damahu variety as a good energy source. However, its protein content does not yet meet the minimum requirement set by the Indonesian National Standard (SNI) for corn-based processed products. The nutritional profile highlights the potential of Damahu waxy corn for the development of nutritious and competitive local food products. This study provides an initial contribution to the documentation of Gorontalo’s indigenous corn varieties and offers a scientific foundation for the utilization of local germplasm to strengthen regional food security.

Abstract

This study aimed to describe Actinomycetes from the rhizosphere of plants in the Gorontalo karst area as Plant Growth Promoting Rhizobacteria (PGPR). The research method is based on a quantitative descriptive method. Soil samples from the rhizosphere were collected using a purposive sampling technique from 8 plant species at two locations in the Gorontalo karst region, namely the Tanjung Kramat Hills. The characteristics of PGPR in this study focused on phosphate solubilization ability, Indole Acetic Acid (IAA) production, antagonism against the fungus Fusarium oxysporum, and tolerance to fungicides. Potential PGPR isolates were analyzed for phylogenetic relationships based on 16S rRNA gene sequences. The results showed that there were 6 actinomycetes isolates (RzHKC-01, RzKO-02, RzO-03, RzAK-04, RzPK-05, and RzOC-06) from 8 plant species in the Gorontalo karst region. One actinomycetes isolate, RzPK-05, showed potential as a PGPR with the ability to solubilize phosphate and produce IAA at 0.165 mg/L and 0.133 mg/L, respectively. Isolate RzPK-05 exhibited antagonistic properties against Fusarium oxysporum with an inhibition rate of 82.24% and was tolerant to fungicides such as Captive, Benlate, and Thiramo up to a concentration of 100 mg/L. Molecular analysis based on the 16S rRNA gene and phylogenetic tree reconstruction indicated that the RzPK-05 isolate is closely related to the genus Streptomyces with 100% similarity.

Abstract

Coral reefs are the main ecosystem of coastal waters and tropical seas, and their preseance is very dominant in coastal waters and small islands of the Indonesia archipelago. Coral reefs have a very large role, therefore damage to the coral reef ecosystem can result in disruption of all marine and coastal life in the region.CPCe (Coral Point Count With Excel Extensions) is used to observe coral reefs. The data used are the results of photos taken using the UPT (Under Photo Transect) method from 2 observation stations in the waters of Popaya Island (Mas Popaya Raja Nature Reserve). The photos consisted of 51 photos for each station. Photos taken with the assumption that they can represent each station used. Each photo processed in CPCe used 30 random points. The results showed that the highest percentage of coral cover was found at station 1 at 59,8% while the lowest percentage of coral cover was found at station 2 with a value of 35,75%. This shows that the level of damage that occurs in the waters of Popaya Island is higher at station 2.

Abstract

This study aims to determine the composition of vegetation types in the karst area of Gorontalo province and determine the vegetation structure in the karst area of Gorontalo province. The method used in this study uses the square transect method, the transect line is made perpendicular along 100 m, with the plot size being 20 x 20 m for tree strata, 10 x 10 m for pile strata, and 5 x 5 m for seedling strata, The results of vegetation structure analysis based on the highest INP value for tree-level strata at station I are Leucaena leucocephala species 2.20%, at Ceiba petandra station II 1.24%, and at Muntingia calabura station III 1.72%. At the stake level, the Leucaena leucocephala species had the highest INP value of the three stations, which was 1.81%. For the nursery rate, the highest INP is owned by the Leucaena leucocephala species at 2.10%. Based on the results of the analysis using ordinance charts, stations II and III have almost the same formation pattern so that the graph tends to overlap, while for station I it is very different from stations II and III, for station I it has its own formation pattern compared to stations II and III, and station I is also indicated to have its own characteristics based on habitat conditions and environmental factors.
