Abstract

Sistem stres ikan zebra diwakili oleh poros HPI yang serupa dengan poros HPA pada mamalia untuk mengendalikan sirkulasi kortisol sebagai hormon terkait respon stres. Ikan yang berada dalam keadaan stres diduga mempengaruhi perilaku dan preferensi area sesuai dengan parameter yang ditentukan. Tujuan dari penelitian ini adalah menguji efek induksi stres suhu terhadap preferensi area dan perilaku ikan zebra. Penelitian ini dilakukan secara eksperimental dengan parameter uji: preferensi area gelap/terang, preferensi area bawah/atas, dan munculnya perilaku imobilitas dan gerakan tidak menentu. Ikan diamati di tiga akuarium uji secara individual, yaitu akuarium uji gelap/terang, akuarium tangki penyelaman (atas/bawah), dan akuarium uji lapangan terbuka. Data dianalisis secara statistik menggunakan Uji T berpasangan dengan signifikansi P < 0,05. Stres suhu yang diberikan mempengaruhi preferensi area pada ikan zebra, preferensi pada area terang lebih tinggi (rata-rata 33,29 detik/menit) dibandingkan area gelap, preferensi pada area bawah akuarium lebih tinggi (rata-rata 44,96 detik/menit) dibandingkan area bawah, dan perilaku berupa imobilitas dan gerakan tidak menentu ditunjukan oleh ikan zebra sebagai indikasi respon stres. Disimpulkan bahwa perilaku dan preferensi area terpengaruh oleh paparan stresor suhu yang diduga terkait dengan produksi kortisol.

Abstract

Mango is a type of plant that is common in tropical climates, including Indonesia. The pharmacological effects of the mango are contained in almost all parts of the plant, including the mango shoots. The mango shoots are known to benefit as antibacterial, anti-inflammatory, antitumor, antioxidant, and anti-microbial. This encourages many parties to make functional food preparations from mango shoots without destroying the nutrient contains. This study aims to evaluated the effect of adding different types of sweeteners on the quality of mango shoot syrup. This study used a completely randomized design (CRD) with three treatment groups consisting of control (T0), Stevia (T1), and Sugar (T2). Parameters observed included pH value, phytochemical screening, and antioxidant activity. The results showed that the pH values of all treatments ranged from 4.48-4.50 and were not significantly different (P=0.661). In the phytochemical screening test, all treatments showed positive results containing alkaloids, flavonoids, saponins, and tannins. Furthermore, based on the percentage value of the antioxidant activity, significant results were obtained (P = 0.000) with the IC50 value in the stevia treatment (8.98) which was smaller than sugar (19.14).The addition of stevia sweetener has a minimum effect in changing the nutritional content of mango shoot syrup based on the value of the antioxidant activity.

Abstract

Sustained stress is risked for the emergence of various diseases including disability to depression. Clinically, antidepressant drugs are still the main option even though they are known have side effects for users. Therefore, various types of drug plants that have the potential as natural antidepressants have begun to be used, one of them is the young leaf of mango (Mangifera indica). It is known contains various bioactive compounds, including mangiferin which is useful as an antioxidant, anti-inflammatory, and plays a role in protecting nervous tissue. This study aimed to determine the effect of Mango’s young leaves extract of Arumanis cultivar as an antidepressant in zebrafish (Danio rerio) exposed to Unpredictable Chronic Stress (UCS). The method used is Completely Randomized Design (CRD) which consists of 3 treatments, namely K (Aquadest); P1 (extract concentration 10µg/mL); and P2 (extract concentration 20µg/mL). The parameters include the antioxidant activity and behavioral tests, namely new tank diving and light/dark preferences. The results showed that exposure to UCS tends to increased anxiety as indicated by a decrease in exploration on behavioral test. The data showed that the Mango’s young leaves extract induction with a concentration of 20µg/mL obtained the highest value percentage in the exploration of the upper area (36.8 s) and the preference of the bright area (90.8 s) significantly. The induction of mango’s young leaves extract has the potential as an antidepressant in zebrafish exposed to UCS with an optimal concentration of 20µg/ml.

Abstract

Cave crickets are considered as a keystone species that can be used as a cave ecosystem bioindicator. Developing caves as tourism has considerable potential to disturb cave cricket populations. This study aimed to investigate cave cricket population structure and their habitat preference in Sanghyang Kenit cave one year after it developed into a show cave. Data were collected through standardized visual searching in three cave zones: entrance, twilight, and dark. Besides cave crickets, other macroarthropods discovered in each zone were also recorded. Abiotic parameters of habitat comprised air and soil temperatures, RH, soil moisture, soil pH, and light intensity were measured. Data were analyzed to show cave crickets abundance, density, sex ratio, and age structure. Statistical analysis comprising Kruskal Wallis, non-metric multidimensional scaling, and correlation tests were performed. The cave cricket population in Sanghyang Kenit belonged to a single species, Rhaphidophora sp. The population was around 78-108 individuals and distributed in all cave zones. The abundance and density in twilight and dark zones were significantly higher than in the entrance. The number of males outperformed females with a 2.16 ratio. Besides, the population was dominated by the sub-adult class. Environmental parameters of twilight and dark zones tended to be similar to one another compared to the entrance. Cave crickets preferred habitats with dark, humid, and acidic soil pH. Heteropoda sp. and Catagaeus sp. were considered potential predators. This study implies the importance of protecting cave crickets in Sanghyang Kenit.

Abstract

Sludge is a suspension of liquid waste and microorganisms originating from the Wastewater Treatment Plant (WWTP). The humus and nutrient content of sewage sludges can be used as compost by the vermicomposting mechanism. This study aims to determine the potential of sewage sludge in the Integrated Laboratory of UIN Sunan Gunung Djati Bandung as a raw material for making organic fertilizer through vermicomposting by utilizing the earthworm Eisenia fetida. The media containing a mixture of cow dung (CD) and sludge (S) was divided into four treatments consisting of Control (100% CD), P1 (75% CD + 25% S), P2 (50% CD + 50% S), and P3 (25% CD + 75% S) with the weight of each medium is 500 grams. A total of 20 adult earthworms (5-6 grams/20 heads) were added to each treatment medium for the vermicompost process for 8 weeks. The results showed that the composition of the media in treatment P1 showed the highest effect on the quality of vermicompost with percentages of C (42.62), N (1.85), P (1.21), and K (0.26) based on the SNI 7763-2018 standard. The conclusion of this study is that the sewage sludges from the Integrated Laboratory of UIN Sunan Gunung Djati Bandung can be used as raw material for making organic fertilizer with an optimum media composition of 75% CD + 25% S.

Abstract

The Javan gibbon (Hylobates moloch) is one of the endemic primates that are protected on the island of Java. The results of research and surveys show that the Javan gibbon population in its natural habitat has a declining trend. Conservation efforts that can be done to rebuild the Javan gibbon population in the wild are by releasing them. For release, careful preparation and consideration is needed because the Javan gibbon has a high level of sensitivity to disturbance. This research was conducted at the Javan Primate Rehabilitation Center (JPRC) The Aspinall Foundation with the aim of knowing the release readiness status of the Javan gibbon pair based on 4 release criteria consisting of permanent partner readiness, daily activity readiness, health readiness and ability to consume natural food. The study was conducted on two pairs of Javan gibbons targeted for release, namely Udin-Lola and Joy-Bobby. Observations were made from January to February 2022 using the ad libitum method and scan sampling with an interval of 5 minutes . The results showed that based on 4 criteria for release, both partners were declared to have met the criteria for release, except for the status of the ability to consume natural food. During the observation, copulation activity was not observed, but the Udin-Lola pair was seen several times carrying out pre-copulation activities. Based on the value of readiness for release, the Udin-Lola pair were categorized as ready to be released into the wild with scores of 74.2. Meanwhile, the Joy-Bobby couple is not ready to be released with a score of 68.6.

Abstract

Kondisi penuh tekanan seperti isolasi sosial yang dialami individu terbukti akan memicu ketidaknyamanan dan mempengaruhi kesehatan mental. Penelitian ini bertujuan mengetahui respon stress yang muncul sebagai konsekuensi dari isolasi sosial pada ikan zebra dewasa (Danio rerio). Hewan uji yang digunakan yaitu ikan zebra yang ditempatkan secara individual pada akuarium isolasi untuk menyelidiki perilaku stres. Pengujian perilaku stres dilakukan dengan  uji gelap terang, uji novel tank dive dan uji lapangan terbuka. Pada uji gelap terang, ikan zebra yang diisolasi cenderung menghabiskan waktu pada area gelap daripada area terang yaitu 34,72 detik. Ikan zebra yang diisolasi menghasilkan waktu lebih lama pada area bawah dibandingkan di area atas yaitu selama 53,07 detik pada uji novel tank dive. Uji lapangan terbuka menunjukan perilaku tidak menentu pada ikan zebra yang diisolasi yaitu selama 16,01 detik dan perilaku immobilitas selama 14,60 detik. Berdasar pada hasil penujian respon stres diperoleh hasil bahwa isolasi sosial yang dilakukan pada ikan zebra (Danio rerio) dapat menyebabkan perilaku stres.
