Abstract. Tuhumury NC, Sahetapy JMF, Matakupan J. 2024. Isolation and identification of bacterial pathogens causing ice-ice disease in Eucheuma cottonii seaweed at Seira Island Waters, Tanimbar Islands District, Maluku, Indonesia. Biodiversitas 25: 964-970. Seaweed cultivation has proven to be beneficial and enhances the well-being of communities. Production of seaweed in the waters of Maluku has increased despite facing the problem of ice-ice disease. Therefore, this research aimed to isolate and identify bacteria on the Eucheuma cottonii seaweed species affected by ice-ice disease in the waters of Seira Island, Tanimbar Islands District, Maluku. It was conducted in August 2023 at three observation stations, and water quality samples were collected in situ at all three stations, including temperature, salinity, pH, dissolved oxygen (DO), and turbidity. Furthermore, bacterial isolation and identification were carried out at the Laboratory of Marine Aquaculture, Ambon. Bacteria isolation and purification were performed on TCBS media using the streak plate technique, while identification used the API 20E test. The results showed that water quality parameters supported seaweed growth. Four bacteria that caused ice-ice disease in the waters of Seira were identified as Vibrio alginolyticus, Vibrio fluvalis, Vibrio cholerae, and Aeromonas caviae. Moreover, all four bacteria found were gram-negative and pathogenic. Bacteria belonging to the genera Vibrio and Aeromonas have been proven to cause infections in marine organisms, including seaweed. In conclusion, four types of bacteria were identified in seaweed affected by ice-ice disease.

Abstract. Anwar A, Zainuddin, Djawad MI, Aslamyah S. 2023. Fermentation of rain tree (Samanea saman) seed meal using mixed microbes to improve its nutritional quality. Biodiversitas 24: 5863-5872. Rain tree (Samanea saman) seed meal is a source of protein; however, its utilization remains limited due to the presence of anti-nutrients, such as tannins acting as protein inhibitors, high crude fiber content, dissolved protein, and low digestibility of dry and organic matter. Fermentation using mixed microbes potentially enhances the nutritional value of rain tree seed meal. This study aims to improve the nutritional quality and reduce anti-nutritional factors in rain tree seed flour using mixed microbes at various doses and incubation times in vitro. Microbes utilized in this study include Bacillus sp., Saccharomyces cerevisiae, and Rhizopus sp. The study was designed using a Factorial Completely Randomized Design, using two factors, i.e., 3 doses of mixed microbes (0, 1.5, 3, and 4.5 mL/100 g rain tree seed meal) and 3 different incubation times (42, 72 and 96 hours). There were significant interactions between the microbe doses and incubation times. The treatment of 4.5 mL of mixed microbes/100 g rain tree seed meal and a 72 hours incubation time reduced substantially crude fiber content (59.60%) and crude fat (73.20%), coupled with an increase in crude protein content (11.62%), NFE (6.52%), dry matter digestibility (DMD) (36.78%), organic matter digestibility (OMD) (50.42%), and dissolved protein content (20.27%). Tannin content reduced significantly (37.72%) at the treatment of 4.5 mL of mixed microbes/100g rain tree seed meal with an incubation time of 96 hours. These findings suggest that rain tree seed meal, subjected to fermentation for 72 hours or more, improves nutritional quality, DMD, and OMD.

Abstract. Eddy S, Setiawan AA, Taufik M, Oktavia M, Utomo B, Milantara N. 2023. Loss of carbon stock as an impact of anthropogenic activities in a protected mangrove forest. Biodiversitas 24: 6493-6501. The significant anthropogenic activities within the mangrove forest, known as the Air Telang Protected Forest (ATPF) in the Banyuasin District, South Sumatra, Indonesia, have led to an alarming degradation, leaving only its primary mangrove forests, currently constituting approximately 26% of the total forest area. This study aims to analyze changes in land cover, quantify carbon reserve loss due to CO2 emissions, and assess carbon sequestration in the ATPF over two periods: 1999-2010 and 2010-2023. Remote sensing data for 1999, 2010, and 2023 were utilized from Landsat imagery, employing ENVI and ArcGIS for land cover classification. Carbon density, CO2 emissions, and carbon sequestration were analysed using the Land Use Planning for Multiple Environmental Services (LUMENS) software. The research findings reveal an increase in the primary forest area in the first period (by almost a quarter); however, more than half of this area was lost in the second period. The secondary forest area consistently decreased over the two periods, while the open area experienced significant growth. Carbon stocks in 2010 exceeded those in 1999 due to an increase in the primary forest area, but by 2023, carbon stocks decreased significantly due to extensive land clearing. The second period witnessed the largest emissions, exceeding those of the previous period by five times. Carbon sequestration in the first period surpassed that in the second period by more than three times, with the most significant sequestration resulting from the growth of secondary mangrove forests into primary mangrove forests. The study highlights the necessity of restoration and conservation of mangrove forest areas in ATPF for sustenance of its natural function as a protected forest.

Abstract. Gojo-Cruz PHP, Caldito JC, Catubig YDL, Cornes HM, Corpuz JS, Maniquiz SS, Matunan KGE, Pascual FJ, Miguel ESS, Siguancia GC, Turqueza DC, Madlao JP, Cruz CF, Merculio JG. 2024. Terrestrial vertebrate fauna in a multifunctional landscape in Gabaldon, Nueva Ecija, Philippines. Biodiversitas 25: 583-597. This study was done to document the vertebrate fauna in a multifunctional landscape at the foothills of Mt. Mingan, Gabaldon, Nueva Ecija. The inventory of wild vertebrate fauna associated with the different habitat types in the area will be valuable in creating suitable management programs to reduce the impact of human activities in the area without affecting local economic activities. Standard survey techniques, including day and night transect walks, opportunistic surveys, mist-netting, and cage trapping, were employed to document vertebrate fauna in the agro-forest, around built-up areas, forest edges, lowland forest, grassland, and riparian habitats. A total of 79 species of vertebrate fauna were recorded, including 7 species of mammals, 13 species of reptiles, 9 species of amphibians, and 50 species of birds. Thirty-three (33) species were endemic to the Philippines. Regarding conservation status, eight (8) species were listed in the higher threat status under DAO 2019-09. Species richness was observed to be highest in lowland dipterocarp forests. On the other hand, species composition varies between habitats, with endemic species being more common in complex habitats such as lowland dipterocarp forests than in simpler habitats like agricultural areas. The high species richness and the presence of endemic and threatened species in the multifunctional landscape of the area highlight the need for management plans considering habitat heterogeneity and connectivity.

Abstract. Yongco JE, Amparado OA, Naive MAK. 2023. Short Communication: Rediscovery of the Zamboanga peninsula endemic Boesenbergia longipetiolata (Ridl.) Merr. (Zingiberaceae) after over a century, including an amended description and an updated distribution. Biodiversitas 24: 6305-6309. Zamboanga Peninsula is one of the important sites for biodiversity studies in the Philippines. Despite that, there have been limited attempts for field explorations focusing on the floral diversity and plant inventories in the region, resulting in the scarcity of floristic data and has left many of its plant species, including their status, unknown. Included is Boesenbergia longipetiolata, a poorly known plant species belonging to the Zingiberaceae family, endemic to the Zamboanga Peninsula, Western Mindanao, Philippines and considered a long-lost species as its existence had not been reported since it was first collected in 1909. A meticulous examination of a specimen collected from a recent botanical exploration conducted in Mount Timolan Protected Landscape of Zamboanga Peninsula in July 2022 revealed the rediscovery of B. longipetiolata after a lapse of over a century. This species is unique among all other Philippine endemic Boesenbergia species by having a very long petiole and is closely similar to the Malay Peninsula endemic B. longipes but differs significantly by having lower stature, narrowly ovate to lanceolate lamina, a longer calyx and a slender corolla tube. In this study, an amended taxonomic description, including information on its geographical distribution and habitat, and a proposed conservation status are provided.

Abstract. Widajati E, Syukur M, Diaguna R, Permatasari OSI, Ritonga AW, Sahid ZD, Pratiwi GR, Hatta ANNL. 2023. Morpho-physiological seed diversity and viability of Indonesian cowpea (Vigna unguiculata). Biodiversitas 24: 5319-5327. Cowpea is a legume with a potential nutritional content almost equivalent to soybeans; it can be developed as a substitute agent for raw materials for food processing. One of the factors in obtaining high cowpea production is to use of quality seeds. Our study aimed to evaluate the performance and morpho-physiological correlations and viability of cowpea seed collections from IPB University Bogor and the Indonesian Research Institute of Legume. We used ten genotypes of cowpea, which had superior seed information. The results showed that the ten cowpea genotypes had superior morpho-physiological and seed viability. The seed germination percentage was categorized as medium-high (>60%). Eight cowpea genotypes were grouped into one major group based on morpho-physiological characteristics and viability. Furthermore, positive correlations were found between the observed variables of seed viability (seed germination, seed growth speed, and seed vigor index). Our research results are useful as a source of genetic diversity for plant breeders in developing new superior varieties in the future. In addition, agronomists can use this information to plant cowpeas based on planting location.

Abstract. Djamaludin H, Sulistiyati TD, Chamidah A, Nurashikin P, Roifah M, Notonegoro H, Ferdian PR. 2023. Quality and fatty acid profiles of fish oil from tuna by-products extracted using a dry-rendering method. Biodiversitas 24: 5757-5763. Tuna is an export commodity with a high-fat content, making it a valuable source of fish oil. However, a substantial portion of tuna, including viscera, eyes, and liver, some parts are underutilized, leading to waste. The study aims to determine the impact of extraction temperature (50°C, 60°C, and 70°C) on the yield, peroxide value, free fatty acids (%), p-anisidine value, and total oxidation value of the extracted oil from tuna (Euthynnus sp.) by-products. This research used the dry-rendering method to extract crude oil from tuna by-products and analyze quality characteristics and fatty acids. The results from the proximate value indicated that the crude lipid content in tuna by-products ranged from 13.03% to 19.01%. Extraction temperature significantly affected the yield, with the highest yield at 70°C correlating with the highest lipid content in innards. The lowest peroxide value is obtained from an extraction temperature of 50°C from all parts of tuna by-products, ranging from 2.01 to 2.09 meq/kg. Free fatty acid (%) levels in this study met the International Fish Oil Standards (IFOS), and different temperature treatments had a significant effect (P<0.05). The lowest value of p-anisidine, 6.11 meq/kg, was obtained from an extraction temperature of 50°C for innards samples, and the p-anisidine value increased with temperature, reflecting secondary oxidation products. The total oxidation lowest value was obtained from extraction at 50°C (14.84 meq/kg) from viscera by IFOS (?20 meq/kg), and it was within acceptable limits. The fatty acid profile of the crude extract of tuna by-product oil resulting from extraction at a temperature of 50°C, where extraction results at 50°C obtained a fatty acid profile of saturated fatty acids>mono-unsaturated fatty acids>polyunsaturated fatty acids, with significant levels of omega-3 fatty acids such as eicosapentaenoic acid and docosahexaenoic acid.

Abstract. Takarina ND, Soeprobowati TR, Komala PS, Subehi L, Wojewódka-Przyby? M, Nurdin D. 2023. Shell size distributions, land use, and water quality relationships of a freshwater apple snail Pomacea canaliculata (Lamarck, 1822) in Maninjau Lake, West Sumatra, Indonesia. Biodiversitas 24: 5478-5484. The freshwater apple snail, Pomacea canaliculata (Lamarck, 1822), is a common mollusk in lake ecosystems, including Maninjau Lake, West Sumatra. Despite its presence in Maninjau Lake, the information about its shell size, land use, and water quality variable relationships is very limited. This paper aims to study how the land use surrounding the lake and water quality variables can affect the shell size distributions of P. canaliculata. The samples were collected from several locations representing the varieties of land uses, including settlements, paddy fields, forest covers, and river mouths, along with water quality variables. Statistical analysis was done using ANOVA and validated by Tukey's post hoc test to analyze differences among locations. Pearson’s correlation test was used to analyze the relationship between shell size and water quality variables. The results show that the differences in land use and water quality variables affected the variations of shell length (P < 0.05, F = 4.925) and width (P< 0.05, F = 12.369) of P. canaliculata. The average shell length was 2.709 cm and 2.022 cm for the width. The large shell size was observed in settlement land uses (P< 0.05), and the small shell was observed in forest and paddy field land uses (P< 0.05). The water near settlement land uses was characterized by high temperatures, while colder water was observed in forest and paddy field land uses. Pearson’s test confirms that increases in shell length and width were correlated with increases in temperature and dissolved oxygen.

Abstract. Fatmawati M, Suwanti LT, Mufasirin, Subekti DT, Ekawasti F, Lastuti NDR, Lamid M, Suprihati E, Effendi MH, Al-Arif A. 2023. Optimization of deoxyribonucleic acid extraction and polymerase chain reaction methods for gene detection of Toxoplasma gondii in goat milk. Biodiversitas 24: 5905-5911. Dairy goats (Capra aegagrus hircus) are intermediate hosts that transmit Toxoplasma gondii to humans through goat milk consumption. T. gondii can invade mammary glands and secrete into milk. The method of detecting gene of the T. gondii in milk is through a Polymerase Chain Reaction (PCR) test based on specific genes. The objective of this study was to compare the efficacy methods of the T. gondii molecular assay from the extraction, master mix for PCR assay, and primer that is possible to amplify the gene of T. gondii in goat milk for PCR assay. The research method for purification used flotation using concentrated sugar. This research compared the extraction kit from Kit Extraction 1 (K1), Kit Extraction 2 (K2), and Kit Extraction 3 (K3) with the extraction method listed in the brochure. Meanwhile, for the PCR assay, three types of master mix were used, including Master Mix 1 (M1), Master Mix 2 (M2), and Master Mix 3 (M3). The specific genes used included primers B1, ROP, GRA 1, GRA 7, BAG 1, and P30. Tris borate EDTA (TBE) or Phosphate Buffer Saline Solution (PBS) as buffer milk samples gave the same PCR test results. The results show that the principle of a flotation method test using PBS can be used to prepare the milk sample. The research showed that extraction kit 1 (K1) and extraction kit 2 (K2) gave positive results for the positive control. However, in terms of price, K2 is cheaper than K1. So, to optimize DNA extraction, K2 can be used. The master mix that can be used for PCR testing of milk samples is M1 because M1 gives positive results for positive controls and negative results for negative controls. Primers for optimal results used GRA 7 and B1 with denaturation temperature of 94°C, annealing at 56°C, and an extension of 73°C 33. This research concluded that the type of DNA extraction kit affects the PCR test results for detecting T. gondii in goat milk. It is necessary to optimize the type of master mix to be used in PCR testing and primers capable of amplifying the T. gondii gene.

Abstract. Herlinda S, Suwandi S, Irsan C, Adrian R, Fawwazi F, Akbar F. 2023. Species diversity and abundance of parasitoids of fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) from South Sumatra, Indonesia. Biodiversitas 24: 6184-6190. The parasitoid species attacking Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) have never been reported from South Sumatra. The objectives of this research were to identify and analyze the species diversity of egg and larval parasitoids of S. frugiperda and to determine their abundance in corn fields from South Sumatra. Surveys were carried out in Ogan Komering Ilir District, Ogan Ilir District, Muara Enim District, and Palembang City. The results showed that fourteen species of parasitoids were found attacking eggs and larvae of S. frugiperda in South Sumatra. Two species were egg parasitoids (Telenomus remus (Nixon) and Trichogramma sp.), and 12 species of larval parasitoids (Chelonus formosanus Sonan, Chelonus oculator F., Chelonus annulipes Wesm., Chelonus cautus (Cresson), Microplitis manilae Ashmead, Microplitis marshallii Kokujev, Euplectrus corriemoreauae Hansson, Compsilura concinnata (Meigen), Sarcophaga sp., Macrocentrus sp., Exorista sp., and Megaselia sp.). The most abundant species of the parasitoids found was T. remus. The highest species diversity was found in Muara Enim District. The number of parasitoid species was greater in the dry season compared to the rainy season. Egg parasitism rates were significantly higher at the corn vegetative stage (59.03%) compared to the generative stage (53.56%).
