Abstract

This study analyzes macrozoobenthos diversity and functional feeding group in Berembang River, Kubu Raya Regency, West Kalimantan. The obtained macrozoobenthos were identified to the genus level, and their functional feeding group was determined through a literature study. Data on diversity, evenness, and dominance were analyzed descriptively. Diversity (H') and Evenness (E) of macrozoobenthos in Berembang River were low (H'=0.73 and E=0.15) while Dominance (C) was high (C=0.81) as evidenced by a large number of genera Corbicula and Gammarus. Macrozoobenthos functional feeding groups found at both stations can be divided into six categories, namely shredders, gathering collectors, deposit feeders, sub-surface deposit feeders, filtering collectors, and scrapers.

Abstract

The behavior of both acoustic and visual signals has been observed in Staurois gutattus black-spotted rock frogs. The aim of the study was to determine how S. gutattus frogs communicate to find their mates through acoustic and visual signals. This research was conducted in Mount Poteng, West Kalimantan. Data were analyzed descriptively and graphically to explain the relationship between the measured parameters. Data collection of advertisement call, foot-flagging and amplexus behavior is done directly in the field. All activities carried out are recorded with the camera. The duration of each part of the breeding activity is also calculated using a stopwatch. The male frog's advertisement call and foot-flagging are carried out by the male frogs while attracting their mates to mate. Where the foot-flagging activity was mostly carried out on the rock substrate (62%), while on the leaf substrate advertisement call was more dominant (47%). Then based on the duration, activity advertisement call, foot-flagging and amplexus the longest duration was performed by male frogs in the time range 18.00-05.59. Meanwhile, from the number of individuals, the advertisement call, foot-flagging and amplexus activities were mostly carried out at 18.00-05.59.

Abstract

The Nypha Palm Worm Namalycastis rhodochorde has been used as bait for fishing in Pontianak. Culturing the worm is one potential effort for its commercialization as well as to overcome the overexploitation of the worm which also brings about the degradation of its natural habitat. Samples of the worm were collected from mangrove forest area in Sungai Kakap, West Kalimantan. Fresh sample of gametes from coelomic fluid were observed carefully under compound microscope to determine phase of gamete development. Oogenesis consisted of three consecutive stages namely immature, submature, and mature with ≤40 μm, 40<x<120 μm, and ≥120 μm in diameter, respectively. The spermatogenesis phases consisted of, spermatogonia, spermatid tetrad and spermatozoa.

Abstract

Mercury is a heavy metal that can undergo biomagnification in the tissue of aquatic organisms, including accumulating in the gills of fish. The main accumulation of mercury occurs in organisms that live in polluted waters, one of which is the suckermouth cat fish (Pterygoplichtys pardalis). The purpose of this study was to determine the histological damage of Pterygoplichtys pardalis gills against mercury (HgCl2) exposure. This study used a Completely Randomized Design consisting of six treatments and three replications. The treatments consisted of control; 0.01 0.02; 0.04; 0.08; 0.16 ppm HgCl2 concentration. The results of the study obtained forms of gill damage in the form of edema, hyperplasia, lamella fusion and epithelial lifting. The highest level of damage occurred at 0.16 ppm HgCl2 concentration in the form of a reduction in secondary lamella structure. Exposure to mercury causes damage to P. pardalis fish gills

Abstract

Two species of semelparity Nypa palm worms can only reproduce once during their lifetime lives sympatrically. This reproductive is a unique strategy for allocating energy and fecundity to maximize fertility and larval survival. Information about energy allocation and fecundity of semelparity Nypa palm worms is not yet available. This study aimed to obtain data on the strategy of two species of sympatric Nypa palm worms related to total energy allocation, fecundity, and larval survival. Energy allocation determining by the proportion between reproductive energy and somatic energy. Fecundity was calculated based on the total number of oocytes obtained from the same individual samples used for energy measurement. Larvae survival was counting the trochophore and 3-setigers larvae resulting from fertilization. Energy allocation, fecundity, and survival were analyzed descriptively. The results showed that both sympatric species allocated energy for reproduction. The fecundity of Namalycastis rhodochorde was higher than that of Namalycastis abiuma, but had lower larval survival than N. abiuma. Fecundity in N. rhodochorde is a strategy to compensate for the low survival rate. Meanwhile, N. abiuma had lower fecundity but had high larval survival. Fecundity and larval survival between the two sympatric Nypa palm worm species differed, but both allocated the same energy. Different larval survival yet similar energy allocation is their strategy to survive in the same environmental conditions.    Dua spesies cacing nipah semelparitas yang hanya dapat melakukan reproduksi sekali selama hidupnya ditemukan hidup secara simpatrik. Kemampuan adaptasi ini mengindikasikan adanya strategi yang khas dalam mengalokasikan energi dan fekunditasnya sehingga dapat memaksimalkan fertilitas dan sintasan larva, namun informasi tersebut masih belum tersedia. Tujuan penelitian ini untuk mendapatkan data strategi dua spesies cacing nipah simpatrik terkait dengan alokasi energi total, fekunditas, dan sintasan larva. Alokasi energi dideterminasi dengan menghitung proporsi antara energi reproduksi  dan energi somatis. Fekunditas dihitung berdasarkan jumlah total oosit yang didapatkan dari sampel individu yang sama dengan yang digunakan untuk pengukuran energi. Penghitungan sintasan dilakukan dengan menghitung jumlah larva trokofor dan larva 3-setiger hasil fertilisasi. Data alokasi energi, fekunditas, dan sintasan dianalisis secara deskriptif. Hasil penelitian menunjukkan kedua spesies simpatrik mengalokasi energi untuk reproduksi. Fekunditas Namalycastis rhodochorde lebih tinggi dibandingkan Namalycastis abiuma, namun memiliki sintasan larva yang lebih rendah dari N. abiuma. Fekunditas pada N. rhodochorde merupakan startegi untuk mengimbangi rendahnya sintasan. Sementara itu, N. abiuma memiliki fekunditas yang lebih rendah namun memiliki sintasan larva yang tinggi. Fekunditas dan sintasan larva antara kedua spesies cacing nipah simpatrik ditemukan berbeda namun keduanya mengalokasi energi yang sama. Perbedaan fekunditas dan sintasan serta persamaan alokasi energi merupakan strategi spesies simpatrik untuk dapat bertahan hidup pada kondisi lingkungan yang sama.

Abstract

The Nypa palm worm Namalycastis rhodochorde can be cultivated because it has high economic value; however, knowledge of its reproductive biology is still poorly understood, especially regarding reproductive hormones for engineering and accelerated maturation. This research aimed to obtain profile data of the three reproductive hormones i.e: estradiol, progesterone, and testosterone of Nypa palm worms. Samples were taken from body coelom fluid containing gametes from three stages of development; immature, submature, and mature. Analysis of progesterone and testosterone used the Radio Immunoassay method while estradiol used the Enzyme-linked Immunosorbent Assay method. Analysis of variance was used to determine differences in hormone concentrations based on developmental stages. The concentration of the Estradiol hormone increases with maturation, while the concentrations of progesterone and testosterone do not differ at all stages of development.

Abstract

Nypa palm worm (Namalycastis rhodochorde) is a new species of Polychaeta class found in Sei Kakap area. Apart from being obtained from the river coast, cultivation is one way to get worms, but the cultivation of nypa palm worm is still within the scope of the lab and is done manually. Manual cultivation has a problems, especially in controlling water salinity which affects the survival or survival rate of worm. Therefore, this requires an Internet of Things in installation of worm cultivation. This system aims to control the salinity of the water and then monitor the salinity and temperature of the water as well as the temperature and humidity of the air. Another goal is to control water salinity which affects the survival rate of worms. The results of monitoring and controlling the water salinity will be displayed on a website-based application. Arduino Uno is used as hardware that controls the system, NodeMCU ESP32 is used as a tool to connect to the server, water salinity sensor is used to measure water salinity, DS18B20 sensor is used to measure water temperature, as well as DHT11 sensor is used to measure air temperature and humidity. The results of testing the reading system of each sensor obtained an error value 0,017% and 0,032% water salinity sensors, 0,015% DS18B20 sensor, as well as 0.011% and 0.003% DHT11 sensor. Application of the system can reduce water salinity by 1-3 ppt and resulted in the survival rate of worms by 41%.

Abstract

Onchidiidae merupakan salah satu famili siput tanpa cangkang dalam Pulmonata yang sepenuhnya bernafas menggunakan paru-paru yang dapat ditemukan di ekosistem mangrove. Terdapat 15 jenis Onchidiidae di Indonesia dari 143 jenis di dunia. Minimnya data diduga karena kurangnya penelitian dan publikasi mengenai Famili Onchidiidae. Penelitian ini bertujuan untuk mengetahui jenis-jenis dan karakteristik morfologi siput dalam Famili Onchidiidae yang terdapat di ekosistem mangrove Kecamatan Pemangkat, Kalimantan Barat. Penelitian dilakukan pada Agustus hingga September 2020 di empat titik lokasi di ekosistem mangrove. Metode pengambilan sampel dilakukan dengan handcollecting berbasis waktu pasang-surut air laut. Sebanyak 180 individu dikoleksi pada penelitian ini, yang terdiri lima jenis dari anggota Famili Onchidiidae, meliputi Onchidium typhae (50 individu), Onchidium stuxbergii (35 individu), Platevindex martensi (20 individu), Platevindex tigrinus (15 individu), dan Paromoionchis sp. (60 individu). Anggota Famili Onchidiidae yang ditemukan memiliki variasi ukuran panjang tubuh yang dikelompokkan menjadi Onchidiidae berukuran kecil (Paromoionchis: 18-25mm); berukuran sedang (Platevindex: 32-35mm) dan berukuran besar (Onchidium: 55-60mm). Bentuk tubuh oval, memanjang atau membulat dengan warna tubuh bagian dorsal lebih gelap dibandingkan dengan bagian ventral tubuh kecuali pada P.tigrinus. Karakter pembeda antargenera Onchidiidae yang ditemukan adalah tonjolan pada tentakel mulut, bercak pada permukaan hyponotum, dan perbedaan posisi lubang kelamin.
