Abstract. Novianty R, Antika B, Saryono, Awaluddin A, Pratiwi NW, Juliantari E. 2022. Naphthalene degradation by Pseudomonas sp. strain LBKURCC149 with the addition of glucose as co-substrate. Biodiversitas 23: 5654-5661. Naphthalene is one of the pollutants that cause carcinogens. The biodegradation of carcinogenic naphthalene toxic compounds needs to be done to control pollution. Pseudomonas is one of several bacterial species that can degrading naphthalene. This study aimed to test the effectiveness of Pseudomonas sp. isolated from the land area of ??the Joint Operating Body (JOB) of PT. Siak Bumi Pusako-Pertamina Hulu in degrading naphthalene with glucose as a co-substrate. The potency of three isolates of Pseudomonas sp. LBKURCC148, LBKURCC149, and LBKURCC150 was tested in Minimal Media (MM) containing 0.2 mM naphthalene and incubated for seven days. The Optical Density (OD), pH, decreased concentration of naphthalene and degradation ability parameters were analyzed using UV-Vis spectrophotometer. The results showed that Pseudomonas sp. LBKURCC149 was able to degrade naphthalene by 13.95%. Naphthalene analysis using HPLC resulted in a decrease in the peak area of ??the sample as compared to the control. Based on these findings Pseudomonas sp. LBKURCC149 could be recommended to use to degrade naphthalene pollution.

Abstract. Sinay H, Mahulette F, Yáñez JA. 2022. Determination of free radical scavenging activity, phenolic and flavonoid content of seven corn cultivars from the Southwest Maluku District, Indonesia. Biodiversitas 23: 5974-5981. The variation of corn (Zea mays L.) kernel might be considered as a surrogate indicator of the phytochemical and bioactive content. This study aimed to determine the phenolics, flavonoids, and free radical scavenging activity of seven local corn cultivars from Kisar Island, Southwest Maluku District in Indonesia. Sample extraction was done by the maceration method. Flavonoid content was determined using the Dowd method, and total phenolic content was performed using the Folin-Ciocalteu method. Free radical scavenging activity was determined using the DPPH radical scavenging method. One-way ANOVA was performed with Duncan multiple range tests to assess the differences between corn seed cultivars, and p < 0.05 were regarded as statistically significant. The results show that the total flavonoid content varied from 8.463 mg QE/mg (Putih cultivar) to 40.075 mg QE/mg (Kuning Dalam cultivar). Total polyphenol content also varied between 105.63 mg GAE/mg (Merah Delima Tongkol Putih cultivar) and 136.41 mg GAE/mg (Pulut cultivar). The antioxidant activity by DPPH assay determined that the seven local corn cultivars had IC50 values ??that were similar to quercetin (used as control), some were even lower. The IC50 value of the seven local corn cultivars ranged from 5.56 to 16.96 µg/mL, while quercetin had an IC50 value of 11.97 µg/mL. It was observed that the Merah Delima Tongkol Cokelat, Merah Delima Tongkol Putih, and Putih cultivars had comparable antioxidant activity to the control quercetin. The Merah Darah, Kuning Genjah, and Kuning Dalam cultivars exhibited a statistically significant higher antioxidant capacity than quercetin. These results can contribute to the selection of corn cultivars to harvest for commercial purposes and potential nutraceutical applications.

Abstract. Kamsurya MY, Ala A, Musa Y, Rafiuddin. 2022. Short Communication: Correlation of flowering phenology and heat unit of forest cloves (Syzygium obtusifolium) at different elevations in Maluku Province, Indonesia. Biodiversitas 23: 5593-5599. The phenology and heat unit of the forest clove (Syzygium obtusifolium L.) are important parameters for the efficient maintenance of this plant. This study aimed to describe phenological flowering stages (PFS) and calculate growing degree days for different PFS, which will have a big impact on crop management and understanding the impact of climate variables on crucial phenological events. The research was conducted in Ambon, Maluku Province, Indonesia, for 16 months, from January 2020 to May 2021. Five sample points at different elevations were determined purposively, i.e: Halasi (6 m above sea level (m asl)), Tibang (11 m asl), Oli (125 m asl), Wanat (175 m asl), and Telaga Kodok (214 m asl). The phenology of flowering is separated into 6 stages: the flowering primordia, the appearance of the flower stalk, the perfect flower stalk, the appearance of the flower bud, the flower is fully formed, and the flower starts to bloom. The results showed that the phenological cycle of the forest clove plant was flowering periodically for 365 days. The average temperature of PFS (29oC) in Halasi was higher compared to other locations. It indicates that the lower the altitude, the faster the flowering period. This study found significant correlations between altitude and PFS, except flower stalks appear and flowers will appear. The phenology of clove plants is influenced by the accumulation of heat units, with the highest heat unit value in the flowers start to bloom stage, ranging from 2,983.23 dayso (Telaga Kodok) to 3,128.84 dayso (Halasi). As elevation increases, the number of heat units decreases, so the PFS is delayed. The primordial phase in Halasi appears in August-September while at Telaga Kodok in December.

Abstract. Harahap F, Nusyirwan N, Afiva A, Prasetya E, Suriani C, Hasibuan RFM, Poerwanto R. 2022. Short Communication: Genetic similarity analysis of in vitro cultivated pineapple (Ananas comosus) from Sipahutar, North Sumatra, Indonesia using ISSR markers. Biodiversitas 23: 5623-5628. Sipahutar pineapple from North Sumatra, Indonesia, is considered difficult to breed, resulting in a lack of seed availability. However, tissue culture allows the emergence of somaclonal variations, especially in plantlets undergoing several subculture stages. This study aimed to identify somaclonal variations in Sipahutar pineapple seedlings generated from in vitro culture using Inter Simple Sequence Repeat (ISSR) markers. Fifteen accessions were used in this study consisting of Sipahutar pineapple grown in its original environment, a laboratory environment, acclimatized, and in vitro cultured. Total of 10 primers, of which seven primers detected polymorphisms among the population. This study resulted in a low genetic similarity among the Sipahutar pineapple population. The genetic diversity of Sipahutar pineapple plants propagated by in vitro culture had a similarity level of 75%-94%, showing somaclonal variations in vitro culture. The genetic similarity of pineapple accessions was divided into two main clusters, namely cluster A consisted of 11 accessions and cluster B consisted of 4 accessions. Cluster separation does not correlate to the source of plant materials studied.

Abstract. Rustikawati, Suprijono E, Murcitro BG, Herison C, Sitohang SJ. 2022. Amendment of mycorrhizae and its residual effect on growth and yield of maize (Zea mays) hybrids in coastal land. Biodiversitas 23: 5600-5605. Maize (Zea mays L.) is known sensitive to less optimal environmental conditions. Maize cultivation in coastal land has low productivity due to the availability of low nutrients and the ability to hold groundwater. The addition of mycorrhizal fungi (MF) to the coastal land is expected to improve the root environment suitable for plants. This study aimed to evaluate growth and yield of maize hybrids grown in coastal areas amended with MF and examining its residual effect. The newly developed hybrids, CT34 and CT17, and a commercial check cultivar, BISI-18, were grown on a coastal land with the application of mycorrhizae at the rate of 0, 5, and 10 g.plant-1 in a factorial experiment with three replications. Observations were made on plant height, stem diameter, number of leaves, leaf length, leaf width, leaf greenness, root fresh weight, ear length, ear diameter, number of grain rows, number of grain.ear-1, and grain weight.plant-1. Data were analyzed for ANOVA, and the mean comparisons were conducted with DMRT at a=5%. The results showed that there was no interaction effect between the maize hybrids and the rate of mycorrhizae on any observed variables. The new hybrid of CT34 showed almost similar growth to that of the check cultivar, BISI 18, but the yield was significantly lower. CT34 showed better performance than CT17 on all variables. The application of MF significantly increased stem diameter and root fresh weight, which in turn increased maize yields in the coastal land. Increasing the mycorrhizal rate up to 10 g.plant-1 in coastal lands was ineffective in increasing maize productivity compared to 5 g.plant-1. In a bioassay study on the mycorrhizal residues in the second season, the treatment of 10 g.plant-1 significantly increased maize growth by more than 100% compared to without mycorrhizae.

Abstract. Rambey R, Purba ER, Hartanto A, Prakoso BP, Peniwidiyanti, Irmayanti L, Purba MP. 2022. Short communication: Diversity and ethnobotany of Araceae in Namo Suro Baru Village, North Sumatra, Indonesia. Biodiversitas 23: 6006-6012. For Indonesian people, the variety of Araceae species has risen to prominence as an ornamental plant and a supplemental food source. However, there is still a lack of information about some species and their cultivation in some parts of North Sumatra. This research was conducted in the village of Namo Suro Baru, Biru-Biru District, Deli Serdang, North Sumatra to identify and study the ethnobotanical use of the species of Araceae. A total of 48 plots, each measuring 2 × 2 m were constructed, and 30 respondents from the community were interviewed about the local utilization of aroids. The results of vegetation analysis recorded a total of 17 species of Araceae plants in the village of Namo Suro Baru in Biru-Biru District, Deli Serdang Regency, North Sumatra Province. Xanthosoma sagittifolium was the dominant species with the highest IVI, i.e. 40.44%, while Dieffenbachia seguine had the lowest IVI (0.86%). The parts of the plant that the locals had traditionally used were the tuber, petiole, and whole leaf. The four main purposes of using Araceae plants were classified as foods, feeds, herbal formulations or medicines, and ornamental plants. Two species of corpse flowers, Amorphophallus titanum and A. prainii, also periodically bloomed in the village, but because they are protected species, the locals did not use them for their needs.

Abstract. Novia R, Ardiningsih P, Adhityawarman, Sarwiyati. 2022. Characteristics of Lactic Acid bacteria isolated from traditional fermented fish. Biodiversitas 23: 5662-5669. Lactic acid bacteria (LAB) are commonly involved in most food fermentation and contribute to the process’s quality and safety. The study investigates the characteristics of LAB isolated from buduk, pekasam, and pekasam ale-ale. Twelve colonies each sample were isolated and identified based on morphology and biochemical test. The pekasam ale-ale isolates were identified as Pediococcus sp. strain A1 and Pediococcus sp. strain A3; Enterococcus sp. strain A2 and Enterococcus sp. strain A4. The LAB in buduk were identified as Streptococcus sp. strain B1, Pediococcus sp. strain B2 and Pediococcus sp. strain B4, Enterococcus sp. strain B3. The pekasam isolates were identified as Pediococcus sp. strain P1, Streptococcus sp. strain P2 and Streptococcus sp. strain P4, Lactobacillus sp. strain P3. The LAB showed antimicrobial activities while Lactobacillus sp. strain P3 and Streptococcus sp. strain P4 could grow at pH 1. Two LAB including Enterococcus sp. strain A2 and Pediococcus sp. strain P1 showed amylase activity while Pediococcus sp. strain A3, Streptococcus sp. strain B1, Pediococcus sp. strain B2, Enterococcus sp. strain B3 showed protease activity. All LAB produced organic acids with varying concentrations at different incubation times. Furthermore, those isolated from various fish fermentations showed different genera and characteristics. Lactobacillus sp. strain P3 was the best to initiate food fermentation and a probiotic candidate based on their characteristics.

Abstract. Ermawati D, Panjono, Bintara S, Hartatik T. 2022. Diversity of partial sequence leptin gene (Exon 3) in crossbred cattle compared to GenBank database. Biodiversitas 23: 5614-5620. Genetic marker method that is often used to select cattle is Single Polymorphism Nucleotide (SNP). Single Polymorphisms Nucleotide (SNP) has been found in various candidate genes, one of which is the leptin gene. Leptin is a gene that affects reproduction and cattle weight. Therefore, this research aims to identify SNP of the leptin gene (exon 3) in Crossbred cattle by comparison with GenBank data. A sample of Crossbred cattle was taken from Klaten in Central Java, Indonesia. Afterward, DNA sequencing results were analyzed with BioEdit to identify SNP. BioEdit software was used for DNA sequencing alignment part of intron 2, exon 3 and 3'UTR. The MEGA 11.1.1 program was used to analyze and edit the genetic distance and phylogenetic tree based on the SNP leptin gene. The result shows that nine variations of SNPs were found in exon 3. The phylogenetic tree shows that the Crossbred cattle, Bos taurus, Bos indicus, Hereford, Friesian Holstein and Bali, were in the same cluster. HindIII restriction enzyme can be recommended for genotyping Crossbred cattle using PCR RFLP. This research provides information on SNP in the leptin gene so that it can be used for further research on the association of the leptin gene to growth and reproduction.

Abstract. Zheng C, Zhu J, Yang X, Fu B. 2022. Short Communication: Genetic diversity of walnut blight-associated bacteria from China using rep-PCR. Biodiversitas 23: 5681-5686. Walnut blight is caused by the bacterium Xanthomonas arboricola pv. juglandis (Xaj), is one of the most serious diseases in walnut production around the world. Understanding the genetic diversity of walnut blight pathogen is of great significance to developing a scientific and reasonable prevention and control strategy. The rep-PCR (Repetitive Sequence Polymerase Chain Reaction) technique is a powerful tool for analyzing plant pathogens. In this paper, using three pairs of rep-PCR universal primers (ERIC, BOX, and REP), a genetic diversity analysis was carried out on walnut blight-associated bacteria mainly isolated from different counties of Hubei Province, China. A study of 60 walnut blight-associated bacteria isolated in 2016 found that they had a high genetic similarity among them. There is no clear correlation between the genetic diversity of these isolates and their geographical or tissue origins. Interestingly, these clusters can also distinguish copper-resistant isolates from sensitive ones. Therefore, rep-PCR is a powerful tool to study the population of walnut pathogenic bacteria.

Abstract. Ramadhan R, Tosepu R, Phuwapraisirisan P, Amirta R, Phontree K, Firdaus YFH, Abdulgani N, Muttaqin MZ, Saparwardi. 2022. Evaluation of non-timber forest products used as medicinal plants from East Kalimantan (Indonesia) to inhibit ?-glucosidase and free radicals. Biodiversitas 23: 5551-5558. Non-timber forest products (NTFPs) have essential uses as medicines, food sources, and traditional ceremonies for the local people living in forest areas. Medicinal plants are one of the non-timber forest products used as traditional medicine by local people in East Kalimantan. This study was conducted to search for new natural antidiabetic and antioxidant resources from medicinal plants used traditionally in Mahakam Ulu District, East Kalimantan, based on ethnopharmacological information. The present study evaluates non-timber forest products as in vitro antidiabetic (rat intestinal ?-glucosidase inhibitory activity) and antioxidant (free radical scavenging activity against DPPH, ABTS, and Nitric Oxide) activities. The antidiabetic and antioxidant activities were evaluated using ?-glucosidase inhibition assay and free radical scavenging methods. This study demonstrated that methanol extracts of Flacourtia rukam Zoll. & Moritzi, Syzygium chloranthum (Duthie) Merr. & L.M. Perry and Shorea balangeran Burck exhibited strong ?-glucosidase inhibitory activity with maltose as a substrate with IC50 values of 0.034 mg/mL, 0.039 mg/mL, and 0.039 mg/mL, respectively. On the other hand, methanol extract of S. chloranthum displayed the strongest ?-glucosidase inhibitory activity in sucrose as a substrate, similar to the IC50 value of the quercetin as a positive control. Furthermore, the antioxidant test showed that all medicinal plant extracts from East Kalimantan are good sources of natural antioxidants indicated by their IC50 values. The results of this study support the scientific background of the uses of medicinal plant extracts from East Kalimantan as folk medicine.
