Abstract

Diptera memiliki keanekaragaman yang cukup tinggi. Resort Pancur Taman Nasional Alas Purwo (TNAP) merupakan salah satu area konservasi yang menjadi preferensinya. Diptera memiliki peran sebagai scavengers, predator, parasitoid, makanan bagi predator, dan penyerbuk dan jasa ekosistem yang berharga. Keberadaan Diptera sangat dipengaruhi oleh faktor lingkungan biotik dan abiotic. Tujuan penelitian untuk mengetahui keanekaragaman Diptera di Resort Pancur TNAP. Metode pengambilan sampel menggunakan metode road sampling. Hasil penelitian ditemukan 8 spesies yang terbagi dalam 6 famili meliputi Musca domestica, Drosophila sp., Chrysomya megacephala, Rhingia sp., Culex erraticus, Aedes aegypti, Aedes triseriatus, Sarcophaga sp. Spesies Culex erracticus memiliki jumlah paling banyak dan banyak dijumpai pada semak- semak dan genangan air. Nilai indeks keanekaragaman menunjukkan keanekaragaman sedang mengarah lingkungan yang baik didukung hasil pengukuran abiotik dalam rentan toleransi.

Abstract

Sanderling (Calidris alba) is a type of shorebird that migrates from the northern hemisphere to the southern hemisphere. Indonesia is a migration route for East Asia-Australasia. The southern coastal area of the Jember Regency, one of the wetlands, especially in East Java, has become an air route and a stopover for shorebirds every year. The research objective was to determine the population of Sanderling (Calidris alba) on the southern coast of Puger and Getem, Jember Regency. Method of collecting encounter rates. Bird watching is carried out in the morning at 06.00-08.00 and in the afternoon at 15.30-17.30. Data recording includes species, number of birds, and other supporting data. Identification using the book by Mac Kinnon et al. (2010) and Bhushan, B., et al. (1993). Tools used for binocular observation, monocular, camera, and GPS. Data analysis used the density index for individual bird species using the formula method (Alikodra, 1990). The results of the study were a total of 445 individuals. Data analysis of Muara Sungai population density was the location with the four other survey locations' highest number.

Abstract

The increasing use of disposable plastic bags is affecting environmental problems because it requires thousands of years to degrade naturally. To overcome these problems, mealworms (larvae of Tenebrio molitor L.) become an alter-native solution. They can be considered as biodegradation agents of plastic because of the presence of symbiont bacte-ria in its gut that secretes plastic-depolymerizing enzymes. Therefore, this study aimed to compare the degradation and digestion ability of T. molitor in consuming various plastic types and thickness. Two designs have also been used: first, comparing the degradation and digestion of various plastic types, and second, comparing the degradation and diges-tion of various plastic bag thicknesses. The first design consists of three types of treatments, and the control group comprised three repetitions. The control group was fed with concentrate; treatment group 1 (P1), PP plastic bags; treat-ment group 2 (P2), high-density polyethylene (HDPE) plastic bags; and treatment group 3 (P3), styrofoam. The second design encompasses two treatment types, and the control group composed of repetitions. The control group was fed with concentrate; treatment group 1 (P1), HDPE plastic bags with a thickness 0.01 mm; and treatment group 2 (P2), HDPE plastic bags with a thickness of 0.02 mm. The result indicates that in the first design, the highest degradation and digestion occurred in treatment 3 (styrofoam) with an average of 0.001267 and 0.0063 fragment/individual, respective-ly. The second design the highest degradation occurred at P1 of 0.000009609 mg/day/individual. The highest digestion occurred at P1 with a total average of 0.004568 fragment/individual.

Abstract

Greater crested tern (Thalasseus bergii) is a common resident seabirds in Indonesia. Habitat beach and rest on the shore with other groups of terns. This study aimed to determine the population of Greater crested tern on the southern coast of Getem Jember.Determination of observation points using a purposive sampling method. Data collection uses the encounter rates method.Bird watching in the morning from 06.00-08.00 and afternoon from 15.30-17.30. Recording data on species, number of birds, and other supporting data. Identify using relevant bird feathers. Analysis of bird species' density index data.Using monocular binoculars, camera, and global positioning system support tools. The survey of four sites revealed 413 individuals of great-crested tern. Analysis of individual density at the mouth of the river 60 individuals/Ha. It was concluded that the River mouth is the most excellent location for greater crested ternThalasseus bergii.
