Abstract

Nyamuk merupakan salah satu serangga yang memiliki peran sebagai vektor dari agen penyakit. Penyakit  yang ditularkan oleh nyamuk masih merupakan masalah kesehatan bagi masyarakat, salah satunya yaitu Demam Berdarah Dengue (DBD). Jenis-jenis penyakit lain yang disebabkan oleh nyamuk adalah Filariasis (kaki gajah), Chikungunya dan Encephalitis. Mojokerto termasuk salah satu wilayah di Provinsi Jawa Timur yang endemis Demam Berdarah Dengue (DBD) di Indonesia, sehingga perlu  diketahui tentang  beberapa jenis nyamuk yang merupakan vektor dari beberapa penyakit yang melanda wilayah Mojokerto. Penelitian ini bertujuan untuk mengetahui jenis-jenis dan distribusi spasial nyamuk di wilayah Mojokerto. Pengambilan sampel dilakukan di dua lokasi di wilayah Mojokerto yaitu di Kecamatan Prajurit Kulon, Kota Mojokerto dan Kecamatan Dlanggu, Kabupaten Mojokerto. Metode yang digunakan adalah survei larva nyamuk dan ovitrap. Titik koordinat lokasi pengambilan sampel disimpan menggunakan GPS selanjutnya dilakukan identifikasi di Laboratorium Ekologi dan Diversitas Hewan, Universitas Brawijaya. Analisis data dilakukan secara kuantitatif untuk menentukan Kelimpahan, Kelimpahan Relatif, Frekuensi, Frekuensi Relatif dan INP (Indeks Nilai Penting). Pola persebaran  nyamuk dianalisis dengan Indeks Morisita. Hasil dari penelitian ini menunjukkan terdapat lima spesies yaitu Aedes aegypti, Aedes albopictus, Aedes laniger, Culex bitaeniorchynchus dan Culex quinquefasciatus. Spesies Aedes aegypti merupakan spesies yang dominan di Kota Mojokerto dengan Indeks Nilai Penting (INP) sebesar 70.48% diperoleh dari metode survei larva dan 76.88% diperoleh dari metode ovitrap sedangkan spesies Culex quinquefasciatus merupakan spesies yang dominan di Kabupaten Mojokerto sebesar 59.80 % diperoleh dari metode survei larva dan 89.58 % diperoleh dari metode ovitrap. Pola penyebaran nyamuk berdasarkan perhitungan indeks morisita di wilayah Mojokerto adalah seragam.   Kata Kunci : Distribusi, Komposisi, Mojokerto, Nyamuk

Abstract

Grasshopper is one type of insect known as a plant pest that quite affects agricultural production. Grasshoppers also have benefits as natural predators and maintain ecological balance. One area where no research has been carried out on grasshopper diversity is Dompu Regency, West Nusa Tenggara, Indonesia. This research was conducted at 4 locations in Dompu, including corn, ex-corn, intercropping, and Doroncanga agricultural land, by making four transects at each location. Grasshoppers were collected using the insect net, and hand collecting was carried out at 07.00 and 16.00 WITA. The environmental factors that were calculated were air temperature, light intensity, wind speed, and air humidity, while the biotic factors observed were plant vegetation at each location and predators. Data analysis was performed using the Shannon-Wiener diversity index, evenness index, dominance index, and Margalef index. The results of this study indicate that Dompu Regency has the potential for diversity of grasshoppers with moderate criteria where the diversity of grasshoppers is strongly influenced by plant vegetation and human treatment on agricultural land.

Abstract

The water quality in Awang Bay, West Nusa Tenggara, Indonesia, is considered to be polluted due to human activities. This research aims to evaluate the water quality in Teluk Awang based on the physicochemical properties of water and zooplankton as bioindicators. Sampling was conducted at three beach locations: Awang, Ujung Kelor, and Ekas. The physicochemical water quality parameters measured included water temperature, pH, dissolved oxygen (DO), salinity, and transparency. Additionally, environmental factors were observed based on the naturalness and hemeroby index. The result of the identification and counting of the abundance of each zooplankton can then be used to analyze including taxa richness, total density, the diversity index of Shannon-Wiener (HSW), Margalef diversity index, Simpson diversity index, evenness index (E), and dominance index (C). The resulting research indicated that the physicochemical water qualities have met government quality standards for marine biota needs, except for the level of transparency at Ekas Station 3. Ekas Beach has the highest level of transparency, diversity, taxa richness, and total abundance of zooplankton, indicating the best water quality. Ujung Kelor Beach, which has the highest level of naturalness and the highest DO concentration, has moderate zooplankton diversity, indicating that the water quality is in the medium category. Meanwhile, Awang Beach, which had the highest human activity and the worst water quality, was characterized by low levels of transparency and DO, low diversity, taxa richness, and an abundance of zooplankton. Therefore, diversity, taxa richness, and abundance of zooplankton can be used as a bioindicator for changes in water quality.

Abstract

Ngesong Spring is a clean spring that is used by society as a spring of clean water and as a tourist attraction. The Ngesong spring has a ditch that flows to the society settlement, where the water is used for agricultural and plantation irrigation. The utilization of the Ngesong Spring as a tourist attraction and its ditch through agriculture, settlements, and society settlements has great potential to cause pollution and degradation of water quality, so it is necessary to evaluate water quality. Therefore, it is necessary to monitor the quality of this water, one of which is the use of the macrozoobenthic community structure as a bioindicator. The research was conducted in four locations, namely, a water spring and the channels that will be used for agriculture, plantations, and settlement activities, in September and October 2022. The variables observed in this study included the physicochemical quality of the water, namely, the water temperature, conductivity, power of hydrogen (pH), dissolved oxygen (DO), biological oxygen demand (BOD), and total suspended solids (TSS), as well as the community structure and macrozoobenthos diversity. The results of this study indicate that 26 macrozoobenthic families belong to 12 orders, for a total of 968 individuals. Water springs had the highest diversity and evenness index values, with H = 2.27 and E = 0.54. The analysis of macrozoobenthic family relationships as an indicator of water quality using the family biotic index (FBI) and average score per taxon (ASPT) showed that the watershed site has very clean water and no organic pollution. At watersheds with good water quality, the families Perlidae, Nemouridae, Limnephilidae, Viviparidae, Chironomidae, and Euphaeidae were found. Moreover, In this study, the locations that have highly organically polluted waters are ditches that have agricultural activities and settlement activities.
