Abstract

In Indonesia, maize has a number of growth constraints and one of which is climate factor. The objective of this research was to determine the growth response of local maize variety. This research was conducted by applying a factorial Randomized Block Design (RBD) with two factors. The first factor is variety (V): pulut, siropu and jakaring (comparison) while the second factor is drought treatment (K) which comprises three treatments including control, drought for 45-55 days after planting (DAP), and drought for 55-65 DAP. In this case, all treatments are repeated three times. The research revealed that the growth of maize indicate different responses towards variety as shown by parameters of plant height, soil moisture content, cob diameter, cob length, cob weight with husks, cob weight without husks, dry weight of root, and number of cob row. Meanwhile the drought stress does not indicate significant response towards growth of maize the drought-tolerant variety of maize with parameter of number of cob raw is siropu local maize.Key words: staple food; local corn; drought stress; growth.

Abstract

This study aims to describe the status of soil fertility and corn yield on different slopes of agricultural land in UPT SP3 Saritani Village, Boalemo Regency. The study used survey methods at 3 land slope locations (20--30%, 30–40%, and 50–60%), determined purposively. Soil samples and maize yields were analyzed quantitatively and descriptively. Corn yields were collected and compared over 3 harvesting seasons based on the parameters of agronomic components. Soil fertility was analyzed at BSIP PALMA Manado laboratory, with parameters including macronutrient components. An essential finding of this study is that there is a difference in corn yield and nutrients on the sloping lands. The fertility status of farmers' land on the average sloped land of the three stations is very low levels of nitrogen and carbon nutrients and high levels of phosphate and potassium. The agronomic components of Stations 1 and 2 were relatively similar compared to the yield of components at Station 3. In the 3 harvest seasons, Station 1's yield decreased every season; from Station 2 it also decreased, but only at the time of the third harvest, although it was insignificant. The yield from Station 3, the steepest field, decreased significantly. Keywords: bisi 18 hybrida, maize, sloping land, soil fertility

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

Manawa merupakan salah satu kawasan di wilayah Kabupaten Pohuwato yang mengalami kerusakan hutan mangrove akibat alih fungsi hutan menjadi lahan tambak dan perkebunan. Rusaknya hutan mangrove berdampak pada berkurangnya berbagai biota laut diantaranya udang, kepiting, dan berbagai jenis ikan. Salah satu upaya perbaikan adalah dengan melakukan rehabilitasi hutan mangrove. Rehabilitasi merupakan salah satu upaya pemulihan ekosistem mangrove pada kondisi semula. Penelitian ini bertujuan untuk mengukur tingkat keberhasilan rehabilitasi Rhizophora apiculata, mengukur tingkat pertumbuhan Rhizophora apiculata, dan menganalisis faktor-faktor yang mempengaruhi keberhasilan Rhizophora apiculata  yang di rehabilitasi di kawasan mangrove Manawa, Kecamatan Patilanggio, Kabupaten Pohuwato, Gorontalo. Analisis keberhasilan mangrove menggunakan analisis deskriptif kuantitatif, dan faktor lingkungannya menggunakan analisis deskriptif. Hasil penelitian menemukan bahwa tingkat keberhasilan rehabilitasi dinilai berhasil. Hal ini dibuktikan dengan persentase keberhasilan hidup Rhizophora apiculata mencapai 79.51%. Tingkat pertumbuhan Rhizophora apiculata baik dari segi tinggi tanaman maupun jumlah daun mengalami pertambahan namun tidak merata pada seluruh plot. Faktor-faktor yang mempengaruhi keberhasilan rehabilitasi mangrove yaitu salinitas dan suhu masih dalam kisaran yang sesuai untuk Rhizophora apiculata. Substrat pada lokasi penelitian didominasi oleh substrat pasir debu. Hama yang ditemukan pada lokasi penelitian tergolong sedang dan didominanasi hama dari kelas Gastropoda.  Manawa, a village in Pohuwato Regency, has suffered damage to its mangrove forest because it was converted into ponds and plantations. A variety of marine biota is reduced when mangrove forests are destroyed, including shrimp, crabs, and a variety of fish species. In the process of improving the ecosystem, one of the improvements is the rehabilitation of mangrove forests. In order to restore the mangrove ecosystem to its original state, rehabilitation is one of the methods. The purpose of this study is to evaluate the success rate of Rhizophora apiculata rehabilitation, measure its growth rate, and determine the factors influencing Rhizophora apiculata rehabilitation in the Manawa Mangrove area, Patilanggio District, Pohuwato Regency, Gorontalo. The success of mangroves was analyzed using quantitative descriptive analysis, and environmental factors were analyzed using descriptive analysis. Results of the study showed that rehabilitation success rates were higher than expected. This is evidenced by Rhizophora apiculata's survival rate, which reached 79.51%. A higher growth rate in plant height and leaves has been observed in Rhizophora apiculata, but not uniformly across the plots. Salinity and temperature, two factors that affect mangrove rehabilitation, remain within the appropriate range for Rhizophora apiculata. The study site substrate is dominated by sand and dust. The pests at the study site were classified as moderate and the most dominant were found in the Gastropod class because the substrate content was suitable for this type of habitat.

Abstract

Seed dormancy is one of the main factors that inhibit the process of germination and plant growth. This study aims to study the effectiveness of using gibberellic acid (GA3) in maintaining the dormancy of rice seeds (Oryza sativa L.) Mekongga variety to increase germination. In this study, Mekongga rice seeds that experienced dormancy were given GA3 treatment with various concentrations. 0.25 ppm, 0.50 ppm, and 0.75 ppm with 24- and 48-hour immersion. The parameters measured include germination percentage, maximum growing potential, dormancy intensity, and sprout length. This research uses a quantitative approach with experimental methods. This study was carried out using a factorial pattern Group Randomized Design (RAK), which consisted of two factors, namely four levels of soaking using three differences in GA3 concentration and one control (aquades) and two levels of seed immersion, namely 24 and 48 hours. The results showed that GA3 treatment in combination concentration treatment had an influence on observation parameters, and there was the best concentration, namely a concentration of 0.25 ppm in 48-hour soaking capable of producing the highest germination of 96.25%, maximum growth potential reaching 98.5% with a dormancy intensity value of 1.5%.

Abstract

Several pathogenic bacteria such as Staphylococcus aureus, Escherichia, Pseudomonas aeruginosa and other pathogenic bacteria have developed resistance to many marketed antibiotics. Staphylococcus aureus is already resistant to several types of antibiotics such as penicillin, erythromycin, cefoxitin, levofloxacin, and clindamycin, Escherichia is resistant to several antibiotics such as Penicillin G, Cefotaxime, Tetracycline, Ampicillin, and Amoxicillin, Pseudomonas aeruginosa has been resistant to antibiotics that target ribosomes, such as tobramycin and tigecycline. The problem of resistance of several pathogenic bacteria can be overcome by finding new metabolite compounds from Actinomycetes microorganisms that have antibiotic potential by exploring extreme areas, one of which is in the karst area, especially in plant roots. Root sampling was carried out by taking samples + 20 cm on each type of plant found. Isolation of Actinomycetes bacteria was carried out using the plate method. Antibacterial activity testing was carried out using the line method. The morphological form of the spores was seen using a SEM (Scanning Electron Microscope). The results of the study found 2 isolates of isolated plant roots containing Actinomycetes bacteria. 2 isolates showed morphological characteristics of mycelium, oval and round in shape and had various colors. The results of the antibacterial activity test showed that each isolate could inhibit several types of pathogenic bacteria, seen from the clear zone with different diameters and the results of SEM (Scanning Electron Microscopy) showed that 2 isolates had the same character and shape of spores as Actinomycetes, namely the genus Streptomyces.

Abstract

Tepurang (Momordica cochinchinensis) memiliki potensi besar dalam bidang farmasi dan pangan, namun keterbatasan bibit dan rendahnya tingkat perkecambahan biji menghambat perbanyakannya. Kultur jaringan menjadi alternatif dalam pelestarian dan perbanyakan tanaman ini, terutama melalui induksi kalus. Penelitian ini bertujuan untuk mengevaluasi pengaruh kombinasi Benzylaminopurine (BAP) dan Indole Acetic Acid (IAA) terhadap induksi kalus dari batang muda M. cochinchinensis secara in vitro. Eksplan berupa batang muda ditanam pada media Murashige & Skoog (MS) dengan kombinasi BAP dan IAA dalam berbagai konsentrasi. Hasil penelitian menunjukkan bahwa perlakuan dengan kombinasi ZPT mampu menginduksi pembentukan kalus dengan warna putih dan tekstur friable setelah 2 minggu subkultur. Temuan ini diharapkan dapat berkontribusi dalam pengembangan metode perbanyakan M. cochinchinensis secara in vitro untuk mendukung konservasi dan pemanfaatannya dalam bidang bioteknologi.
