Abstract

Protecting the nesting habitat of the Moluccan Scrubfowl (Eulipoa wallacei) is important to conserve the population of this endemic species in North Maluku. The success rate of semi-natural hatching nests of Moluccan Scrubfowl varies in each hatchery conservation location. This study aims to determine the nest success of semi-natural hatching program of Moluccan Scrubfowl in Mamuya Village, North Halmahera Regency. A field experiment approach was used to estimate nest success in semi-natural (in-situ) incubation treatments. Eggs used for the semi-natural hatching treatment were collected from landowner egg collecting activities at four Moluccan Scrubfowl nesting sites. In semi-natural hatching, each bird egg was placed in 60 cm of sand with a minimum distance of 10 cm between eggs (egg density adjusted to the number of eggs planted). A total of 116 Moluccan Scrubfowl eggs were planted over four planting periods and during the natural incubation period the eggs hatched producing 96 chicks. The nest success of the semi-natural hatching program for Moluccan Scrubfowl in Mamuya Village has a high success value of 0,835 (83,52%). This optimal success indicates that incubation in the chick embryo formation process is stable on the sand substrate. The mean incubation time interval for hatching eggs lasted 74 days (interval 72 - 76 days)

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pemanfaatan kebun pekarangan untuk pemenuhan pangan keluarga pada masa pandemi covid-19. Pandemi covid-19 berdampak luas pada pelbagai sektor, tidak terkecuali bidang pertanian yang berpengaruh terhadap ketersediaan pangan dan distribusinya. Penguatan produktivitas pangan lokal pada skala rumah tangga atau komunitas menjadi kunci untuk mengantisipasi kelangkaan pangan. Penelitian ini menggunakan pendekatan deskriptif kuantitatif, data diperoleh menggunakan kuesioner semi terstruktur, wawancara, dan pengamatan lapangan. Pemilihan responden menggunakan purposive sampling dengan kriteria inklusi yaitu rumah tangga yang memanfaatkan lahan pekarangan untuk aktivitas berkebun; bertempat tinggal di Kecamatan Tobelo, Kabupaten Halmahera Utara. Hasil inventarisasi tanaman di pekarangan ditemukan 37 jenis dari golongan herba, semak atau perdu, dan pohon. Sebagian besar responden berpendapat bahwa aktivitas berkebun di pekarangan membantu mereka dalam pemenuhan kebutuhan pangan pada masa pandemi covid-19. Masyarakat berpendapat bahwa konsumsi sayuran dan bahan pangan lain dari kebun sendiri relatif lebih aman dan hemat. Selain itu terdapat antusias warga yang giat mengolah tanaman herbal dalam upaya meningkatkan daya tahan tubuh.

Abstract

Research has been carried out with the title identification of mercury pollution in soil at activity locations and post-unlicensed gold mining (PETI) activities in Roko Village, North Halmahera Regency, with the aim of determining the level of pollution and distribution of mercury at PETI and post-PETI activity locations. Sampling used the proportional sampling method in which 5 soil samples were taken at each location. Soil pH measurements were carried out in situ using a Soil Survey Instrument. To analyze mercury concentration in soil, soil samples were taken, preserved, prepared and tested for mercury concentration using a mercury analyzer. The analysis results show that the pH category at the PETI activity location is in the acid category with a pH range of 4.5-5. Meanwhile, the soil pH at the post-PETI location is in the acid to slightly acid category, namely pH 5-6. The results of the analysis of mercury concentrations in the soil at the PETI location ranged from 3.21 mg/kg - 74.99 mg/kg and post-PETI activity locations ranged from 1.76 mg/kg - 167.1 mg/kg at a radius of 0-50 m and has exceeded the normal criteria for mercury in soil and reached the very critical criteria category.
