Abstract. Harahap HA, Yonariza. 2022. Assessing local farmer’s perspectives on the role of bat in providing ecosystem services in the Batang Toru ecosystem, North Sumatra, Indonesia. Biodiversitas 23: 4322-4328. Bats play an important role as pollinators in maintaining the ecosystem services and improving the local economy in Batang Toru Ecosystem (BTE). However, the anthropogenic impacts negatively affect their sustainability, making the evaluation of their services increasingly needed. This study was conducted to examine the local farmers’ action against bats in BTE. The objectives were to analyze: (1) farmers’ knowledge of the role of bats in ecosystem services, (2) the perception of bats, (3) awareness of bat population loss and its impact on durian production, and (4) farmers' actions against bats on their land. The results showed that 1 out of 7 farmers exhibited negative actions toward bats in their agroforest lands. They also had significantly low knowledge about bat services in agroforestry. Most farmers regarded bats as meat for food and medicine rather than as pollinators of durian fruits. We recommend that the government and conservation institutions carry out initiatives to educate farmers regarding the importance of bat services, and conservation efforts should be made to maintain the viable population of bats.

Abstract. Adibah DI, Fuad AM, Budiarti S, Pratiwi RD. 2022. Construction of Saccharomyces cerevisiae KEX2-650 gene expression vector and its introduction into Escherichia coli DH5?. Biodiversitas 23: 4289-4296. Kex2 (EC 3.4.21.61) is a serine protease that binds Ca2+ molecules and naturally found intracellularly as a transmembrane protein. Kex2 has a unique function, the conversion process of recombinant protein precursor into mature protein. Kex2 from Saccharomyces cerevisiae has similar functions also with furin in mammals (about 47% of sequence similarity). To gain advantage, extracellular Kex2 would be highly favorable for this process. This study aimed to construct recombinant Kex2 that could be produced extracellularly in Pichia pastoris host through pD902-KEX2-699 vector (synthetic) with FLAG-tag and 6 His-tag by removing most of C-terminal region, including transmembrane domain (TMD) from KEX2 gene sequence. Constructed KEX2 is the KEX2-650 variant with TMD deletion and cytoplasmic domain. The recombinant plasmid was constructed through site-directed mutagenesis using FP-Kex2-699 and RP-Kex2-650 primers, including the BamHI site for plasmid religation. PCR site-directed mutagenesis produces an amplicon DNA with an expected length of 5551 bp. After restriction (BamHI) and religation, the plasmid was reintroduced into Escherichia coli DH5? and obtained 16 colonies. Verification PCR target gene showed that clones number 9 produced an amplicon of expected length (646 bp). DNA sequencing analysis confirmed that TMD was removed from the gene construct to form the KEX2-650 construct.

Abstract. Hasrianti, Armayani M, Surianti, Putri ARS, Akbar AH. 2022. Analysis of nutritional content and heavy metals of suckermouth catfish (Pterygoplichthys pardalis) in Lake Sidenreng, South Sulawesi, Indonesia. Biodiversitas 23: 3539-3545. Suckermouth catfish (Pterygoplichthys spp.) is one type of freshwater fish that belongs to the category of invasive fish (invasive alien species) in Indonesia based on the regulation of the Indonesian Minister of Marine Affairs and Fisheries Number PER.17/MEN/2009. The presence of suckermouth catfish in Lake Sidenreng with a high population level and increasing over time has resulted in this species dominating the waters. The many impacts caused and the solution has not been found to eradicate the fish, so we need an alternative that can be used to utilize suckermouth catfish, for example, as food to be processed into fishery products. In order to be used as raw material for processed food, a study is needed to determine the nutritional content and heavy metal content in suckermouth catfish. Based on the results of the analysis of the content of crude protein, crude fat and carbohydrate content in the meat of a large (40.3 cm), the content values were 14.52%, 0.49% and 0.21%, while the crude protein, crude fat and fat content were Carbohydrates contained in the meat of suckermouth catfish which are smaller in size (21 cm) are 14.58%, 0.52% and 0.09%. Heavy metals Pb, As, Cd and Hg contained in the meat and scales of suckermouth catfish are also below the metal contamination threshold required based on SNI 2729:2013 so that the fish can be categorized as fish fit for consumption and can be processed into various fishery products with economic value.

Abstract. Fatmawati M, Suwanti LT, Mufasirin, Hambarruk W, Sukesi LE, Rofiah, Novianto E, Wahyuningtyas BK. 2022. A comparative study among dairy goat breeds in Lumajang and Malang, East Java based on milk organoleptic and milk composition. Biodiversitas 23: 2899-2903. The Regencies of Lumajang and Malang have the potential for local dairy goats to support food security and food safety. In Lumajang and Malang there are a diversity of dairy goats that breed Senduro, Crossbreed Etawa, Sapera, and Menggolo. This study aimed to compare the milk quality of various breeds of dairy goats in Lumajang and Malang regencies based on organoleptic and composition tests. The total sample was 161 milk samples from Lumajang (115 dairy goats) and Malang (56 dairy goats). The organoleptic test of milk was carried out by testing the freshness, smell, taste, viscosity, and color of the milk. The milk composition test used lactoscan. The analysis consisted of the Chi-Square test for organoleptic and the Kruskal Wallis for milk composition test. The results show that the quality of goat's milk is of premium quality. The order of milk quality based on fat content is milk from Menggolo, Senduro, Etawa, and Sapera breeds. This study concluded that the breed of dairy goat influence the composition and quality of goat's milk. The milk quality of all dairy goat breeds from Lumajang and Malang was premium quality, but the Menggolo goat is the best, so it can be developed to increase local food productivity.

Abstract. Lestari SR, Choliq FA, Sektiono AW, Hadi MS, Aditya HF, Rahmadhini N, Kusuma RM, Setiawam Y. 2022. Screening of quorum quenching activity of rhizobacteria against Pectobacterium carotovorum subsp. carotovorum. Biodiversitas 23: 4336-4342. Quorum sensing (QS) is a mechanism for determining the virulence of the phytopathogenic bacterium Pectobacterium carotovorum. P. carotovorum carries out the QS mechanism with the chemical compound acyl-homoserine lactone (AHL) to signal and carry out its pathogenicity and virulence. The pathogenicity of P. carotovorum can be prevented through quorum quencher (QQ) activity derived from bacteria that degrade AHL compounds by producing AHL-lactonase. In the present investigation, AHL-lactonase-producing bacteria were isolated from the rhizosphere of carrot cultivation in Bumiaji Sub-District, City of Batu, East Java, Indonesia. The isolated bacteria were screened for quorum quenching activity. Out of thirty-seven isolates, 7 rhizospheric bacteria showed QQ activity against the Chromobacterium violaceum bioindicator. The hypersensitivity test on tobacco plants showed that, five strains SRL07, SRL09, SRL15, SRL21, and SRL35 did not cause a hypersensitivity response. The five isolates were able to suppress the virulence of P. carotovorum in carrot tubers. The 16S rRNA gene sequences of the five isolates had the highest similarity to Bacillus thuringiensis, B. subtilis, and B. cereus. The five isolates were detected to have the gene encoding AHL-lactonase (aiiA). The present study provides new information about the QQ activity of rhizosphere and its potential as a quorum quencher against P. carotovorum.

Abstract. Prabowo H, Rahardjo BT, Mudjiono G, Rizali A. 2022. Stable isotope analysis to assess the trophic level of arthropod in sugarcane ratoon agroecosystem. Biodiversitas 23: 2871-2881. Arthropods represent one of the main components of soil inhabitants and play an important role in maintaining soil health, as well as providing ecosystem services. The description of the trophic level of the ratoon sugarcane agroecosystem is needed to describe the role of organisms in the ecosystem to maximize the role of detritivores, predators, and parasitoids in the ratoon sugarcane agroecosystem. The stable isotope approach is widely used in various studies to describe trophic levels in an agroecosystem. The stable isotope technique, especially the one that uses stable isotopes of carbon (?13C) and nitrogen (?15N), can measure the trophic position that integrates energy assimilation or mass flow through all the different trophic pathways leading to an organism. Stable isotopes ?13C and ?15N can be used to identify the roles of arthropods in the ratoon sugarcane agroecosystem by identifying the composition of both isotopes. The ratio of arthropod's carbon assimilation (?13C) to sugarcane ranges from-1.4 to-5.45‰. In contrast, the ratio of nitrogen assimilation (?15N) of arthropod to sugarcane ranges from 3.86 to 39.7‰. The values of stable isotope ?13C and ?15N on predator and parasitoids are varied. The stable isotope value of carbon (?13C) for predators varies from-10.14 to-11.62‰. In contrast, the predator's stable isotope value of nitrogen (?15N) varies from 9.17 to 18.1%. The parasitoids' carbon stable isotope value (?13C) varies from 10.5 to 11.05‰. In contrast, parasitoids' nitrogen stable isotope value (?15N) varies from 12.8 to 17.05‰. The value of carbon (?13C) stable isotope assimilation between herbivores and predators varies from 0.006 to 1.38‰. While the value of nitrogen (?15N) stable isotope assimilation varies in the range of 0.33 to 10.3‰. Furthermore, the value of carbon (?13C) stable isotope assimilation between herbivores and parasitoids varies in the range of 5.3 to 9.23‰. While the value of nitrogen (?15N) stable isotope assimilation varies in the range of 3.79 to 10.3‰. Isotope content (?13C) shows the food resources of arthropods in the agroecosystem, while isotope value (?15N) shows the roles of arthropods in the sugarcane ratoon agroecosystem. Carbon stable isotope values of predator and parasitoids are close to zero. While the stable nitrogen isotope (?15N) values on arthropods are averagely above 10‰, values are suspected of having roles as predators or parasitoids. Knowing the trophic level of predators and parasitoids through stable isotopes in agroecosystems can be used to conserve and optimize natural enemies to suppress the development of herbivores.

Abstract. Komala PS, Azhari RM, Hapsari FY, Edwin T, Ihsan T, Zulkarnaini, Harefa M. 2022. Comparison of bioconcentration factor of heavy metals between endemic fish and aquacultured fish in Maninjau Lake, West Sumatra, Indonesia. Biodiversitas 23: 4026-4032. Fish have a high risk of accumulating metals and poses a risk of entering human bodies through the food chain. This study aims to analyze the concentration of lead (Pb), mercury (Hg), and cadmium (Cd) spatially and temporally as well as the Bioconcentration Factor (BCF) in endemic fish (Rasbora argyrotaenia) and aquacultured fish (Oreochromis niloticus) in Maninjau Lake and its relationship to environmental parameters (pH, DO and temperature). Sampling was conducted at domestic, hydropower, fish cage, and endemic fisheries. Spatial and temporal distribution using one-way ANOVA with 95% significance, while parameter correlation using linear regression. Almost all heavy metals in both fish samples exceeded the permissible level except in endemic fisheries sites. Metal concentrations in both fish species spatially showed a significant difference, while temporally showed no significant difference. Rasbora argyrotaenia showed a slightly higher BCF value than O.niloticus. The BCF values were low accumulative with order Pb>Hg>Cd ??in R. argyrotaenia and Pb>Cd>Hg for O. niloticus. There is a strong and positive correlation between temperature and the BCF value of both fish species for the three different metals. Monitoring fish by keeping metal content within acceptable limits is necessary. Further research on risk analysis of fish consumption in humans is recommended.

Abstract. Dersita, Rambey R, Muhtadi A, Onrizal O, Mamurung VR, Hasibuan JS, Tamba IS. 2022. Biodiversity of nekton in the Barumun Watershed, Labuhanbatu District, Indonesia. Biodiversitas 23: 2426-2432. Biodiversity is a very valuable source of germplasm for science and sustainable development. Therefore, research on freshwater biodiversity is very important to support the sustainability of this development. The research investigated three rivers in South Labuhanbatu District, North Sumatra, Indonesia: Barumun, Tasik, and Titi Kembar rivers. This investigation aims to ascertain the composition, distribution, and variety of nekton. From April to August 2020, the trial lasted five months. Nekton samples were collected with the aid of nets and fishing nets. While installed in the afternoon, the nets are removed the following day. Additionally, at each observation point, stocking nets were operated three times. The investigation discovered 38 fish species and one shrimp species. Two species of fish discovered, are protected by the government of the Republic of Indonesia. Both fish species are Tenualosa terubuk, a fish with little protection, and Fluvitrygon signifer, a ray fish with complete protection. The study site's sole shrimp species was the gigantic prawn Macrobrachium rosenbergii in the Barumun river. The index of nekton diversity discovered in the three rivers was not identical. Compared to other rivers, the Tasik river station has a high diversity. This makes the Tasik river rich in fish compared to the Barumun and Titi Kembar rivers. The Tasik river is recommended as water suitable for fish life from these results.

Abstract. Santi TD, Siregar TN, Sutriana A, Andini R, Candra A. 2022. Phytochemical test and optimization of transdermal patches of Carica papaya extract: Formulation design of transdermal patch as candidate drug for wound healing. Biodiversitas 23: 2904-2913. Papaya leaves contain metabolite compounds thathave anti-inflammatory and wound-healing properties. This leaf extract as a transdermal patch allows easy application for wound healing. This study aimed to examine the phytochemicals of papaya leaves and determine the formulation of the transdermal patch. This study employed qualitative methods with color testing and quantitative methods with Gas Chromatography-Mass Spectrophotometry (GC-MS) to determine the phytochemical profiles of papaya leaves. The optimization test of patches used Response Surface Methodology with Box-Behnken design on Expert Version 12 software. There were three factors (x) tested in the study, namely PVP, ethyl cellulose, and Ethanol Extract of Papaya Leaves (EECP). There were also three responses (y) investigated, namely thickness, weight, and moisture content. The phytochemical color testingresults revealed the presence of alkaloids, steroid, terpenoid, saponins, flavonoids, phenolic compounds and the GC-MS analysis showed six compounds with the widest areas. From an ANOVA analysist, the p-value was significant (<0.5) while the match value was less significant (p-value >5%). The optimal patch found in this study was the one containing PVP (0.3 mg), ethyl cellulose (0.4 mg), and EECP (0.3 mg). In terms of response values (y), the patch had a ??thickness of 0.25 mm, a weight of 82 mg, and a moisture content of 4.39%.

Abstract. Nio SA, Ludong DPM, Siahaan R. 2022. Short communication: Pattern of chlorophylls content declined during partial submergence for rice varieties cultivated in North Sulawesi at the vegetative stage. Biodiversitas 23: 2451-2456. Submergence or flooding stress limits plant growth in various physiological, anatomical, and morphological aspects. This study examined leaf chlorophyll content as a physiological response in some rice varieties cultivated in North Sulawesi during partial submergence imposed at the vegetative stage. Ten rice cultivars, i.e., Permata, Superwin, Cigeulis, Pulo Manado, TB, Ombong, Serayu, Temo, Burungan, and Inpari 31, were grown in plastic trays on planting media in the greenhouse, then watered to field capacity using a mixture of water and fertilizer every second day for two weeks. The plants were submerged 18 cm from the media's surface, and the content of leaf chlorophylls (total chlorophyll, chlorophyll a, and chlorophyll b) were measured using a spectrophotometer (? 649 and 665 nm) at 0, 3, 6 and 9 days of partial submergence. The chlorophylls (total, a, and b) content decreased during the 9 days of treatment. The highest chlorophylls contents were observed in rice cv. Superwin and the chlorophylls content at day 0 (before partial submergence commenced) were higher than at 3, 6, and 9 days after treatment (p<0.05). The data presented here supported that leaf chlorophylls content is a potential physiological indicator of partial submergence stress in rice, including the North Sulawesi local rice, at the vegetative phase.
