Abstract

This Gelodok fish (Mudskipper) which is called as amphibious fish have unique activity that can live in terrestrial and aquatic area. This study aims to study the daily activities of fish population 2 types of Periophthalmus variabilis and Boleophthalmus boddarti by using the scan sampling method and ad libitum. This research was conducted in September 2017 at the mouth of the river Tluwuk, Pati, Central Java. Observations were made for 150 minutes with a time interval of 5 minutes. The results showed that fish activity P. variabilis (v) was different from B. Boddarti (b).  P. varibilis spends more time on land (90%) than in water (10%) whereas B. Boddarti activity is more in water (60%) than in land (40%). Observed activities are walking (a = 24,08 %., b = 11,73% ), jumping (a = 4.01%, b = 0.65%), feeding / catching prey (a = 5,01%, b = 7.82%), swimming (a = 2.01%, b = 11.72%), moving dorsal fins (a = 4.01%, b = 3.26%), moving caudal fins (a = 2 , A = 2.67%, b = 7.82%), escape predators (a = 3.34%, b = 6.51%), head movements (a = 4.01%, b = 15.63%), entering holes/nesting (a = 0.67%, b = 1.95%), and inactive (a = 40.13%, b = 19 , 54%).

Abstract

Water in the Mount Muria area is needed by the surrounding community to fulfill life. An indicator is needed to determine water quality. Dragonfly (Odonata) is one of the organisms as ecosystem controllers and bioindicators. This study aims to determine the diversity of dragonflies, determine water quality and describe the role of dragonflies as a bioindicator of water quality in the Mount Muria area. This type of research is descriptive quantitative research. The data collection technique used direct observation at 3 stations, namely the Colo Flower River, the Monthel Waterfall River and the River in the Rejenu Area. The results showed that there were 10 species of dragonflies consisting of 6 suborders Anisoptera and 4 suborders Zygoptera with the highest abundance value being Euphaea variegata (51.39%), Enallagma signatum (28.47%), Trithemis festiva (6.94%), Orthetrum glaucum (5.56%), Orthetrum chrysis (2.78%), Orthetrum pruinosum (2.08%), Orthetrum testaceum (0.69%), Orthetrum sabina (0.69%), Prodasineura autumnalis (0.69% ), and Drepanosticta fontinalis (0.69%). Based on water quality analysis and according to government regulation no. 82 of 2001, the water in the muria river belongs to category 2. According to the analysis of the family biotic index, it can be seen that the FBI value of the river in the Muria area is 5.60 which means the condition of the river is fair with moderate pollution levels. ©2019 JNSMR UIN Walisongo.

Abstract

Burung Serak Jawa (Tyto alba) mempunyai peran sangat penting dalam pengendalian hama secara alami ekosistem persawahan. Serak Jawa (Tyto alba) dimanfaatkan petani sebagai agen hayati pengendali tikus sawah seperti yang dilakukan petani Desa Tlogoweru, Kecamatan Guntur, Kabupaten Demak. Penelitian ini bertujuan untuk mengetahui perilaku Tyto alba dalam aktivitas hariannya menggunakan metode scanning-sampling. Jumlah burung Serak Jawa yang diamati di penangkaran sebanyak tiga ekor. Faktor yang diamati seperti: lokomosi, terbang, bertengger, makan, minum, dan bersuara. Pengamatan dilaksanakan selama 12 jam dimulai dari pukul 18.00 WIB sampai 06.00 WIB selama 10 hari di penangkaran Tyto alba Desa Tlogoweru, Guntur, Demak.  Data yang didapatkan dianalisis menggunakan analisis deskriptif. Hasil penelitian menunjukkan bahwa aktivitas harian yang paling banyak dilakukan oleh Tyto alba adalah aktivitas bertengger (393.67 menit), terbang (178.93 menit), lokomosi (62.7 menit), makan (63.7 menit), minum (13.2 menit), dan bersuara (6.77 menit).
