Abstract

Abstrak: Ekosistem mangrove merupakan ekosistem pesisir terdiri dari sekumpulan spesies endemik pantai yang berfungsi sebagai pendukung kehidupan daerah pantai. Luas 11 hektar merupakan Desa Tutuwoto Kabupaten Gorontalo Utara terletak di sana (KPH Gorut, 2010). Desa Tutuwoto, Kecamatan Anggrek, Kabupaten Gorontalo Utara: Kawasan Mangrove dijadikan sebagai lokasi penelitian ini. Periode tiga bulan dari bulan April hingga Juni 2018 saat penelitian ini dilakukan.Sampel Krustacea dikumpulkan dengan alat tangkap sederhana berupa Jaring, Jala, dan seser. Kelimpahan jenis dihitung menggunakan rumus Odum, (1996), Perhitungan keanekaragaman menggunakan rumus (Sannon-wienner). Komposisi Crustacea berjumlah 110 individu, yang terdiri dari 7 Spesies diantaranaya, Scylla serrata sebanyak 15 Individu, Scylla olivacea 14 Individu, Scylla tranquebarica 13 Individu, Carcinus maenas 14 Individu, Metapenaeus elegans 19 Individu, Penaeus latisulcatus, 20 Individu dan Metapenaeus affinis sebanyak 15 Individu.Berdasarkan standar ODUM, nilai keanekaragaman krustasea di lokasi penelitian berkisar antara 1,10 hingga 1,39. Pada tahun 1993, krustasea di lokasi penelitian tergolong dalam kategori sedang karena nilai 1H' adalah 3. Dengan nilai 37,04%, Penaeus latisulcatus mempunyai kelimpahan terbesar, dan 26,79% famili Portunidae mendominasi Scylla serrata. jenis. Crustacea banyak berada pada kategori kelimpahan untuk semua jenis menurut kriteria Michael (1995) karena nilai K lebih dari 20. Semua lokasi umumnya memiliki kondisi lingkungan yang menguntungkan bagi kehidupan krustasea dan bakau.Kata Kunci: Mangrove, Crustaceae, Kelimpahan, Keanekaragaman, Tutuwoto

Abstract

Penelitian ini bertujuan untuk menganalisis produktivitas serasah di kawasan mangrove Tutuwoto Kecamatan Anggrek Kabupaten Gorontalo Utara. Pengambilan data dilakukan dengan metode survey menggunakan penampung serasah (litter trap) berukuran 1meter x 1meter. Data yang diperoleh dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukan perbedaan produktivitas serasah untuk masing-masing jenis. Rhizophora mucronata memiliki produktivitas serasah tertinggi yakni 3,92 gram berat kering/m2/hari (gbk/m2/hr), Rhizophora apiculata 3,89 gbk/m2/hr, Ceriops decandra 2,87 gbk/m2/hr dan Bruguiera gymnorrhiza 1,98 gbk/m2/hr. Serasah daun memberikan kontribusi yang besar di perairan mangrove yakni daun menyumbang 53%—75%; ranting 15%-25%, serta organ bunga dan buah 4%-32%. Mangrove pada strata pohon menghasilkan produktivitas tertinggi dibandingkan dengan mangrove strata pancang. Mangrove strata pohon menghasilkan serasah 1,97—3,92 gbk/m2/hr, dan pancang 1,09—1,58 gbk/m2/hr. Produktivitas serasah di lokasi penelitian dipengaruhi oleh perbedaan spesies, perbedaan strata, dan perbedaan tingkat kerapatan jenis.

Abstract

This research aims to make charcoal briquettes from corn cob organic waste, determine the right type of adhesive to make corn cob charcoal briquettes to produce good quality briquettes, determine the right percentage of adhesive to produce corn cob briquettes to produce good quality briquettes. good and know the characteristics of the best corncob charcoal briquettes which include water content, volatile matter content, ash content, bound carbon content and calorific value. The sample used was corn cob waste obtained from a corn farmer in Botuwombato Village, North Gorontalo Regency. This research uses experimental methods in the laboratory with several stages, namely: material preparation, carbonization, crushing and sieving charcoal, mixing charcoal with adhesive and water, briquetting, drying briquettes, and analyzing the quality of briquettes. From the research results, it was found that alternative energy sources, namely charcoal briquettes, can be made from biomass waste from agricultural waste of corn cobs and candlenut shells. The moisture content of candlenut shell charcoal briquettes is around 14.15% and the moisture content of corn cob charcoal briquettes is around 10.29%. , The test results of the calorific value of candlenut shell charcoal briquettes are around 4173 cal/gr and the calorific value of corn cob briquettes is around 7630 cal/gr.

Abstract

The mangroves in Botudidingga Tourism have an area of ​​around 100 hectares. These mangroves consist of various types, including mangrove, api-api, and nipah. Mangroves in Botudidingga Tourism have an important role in preserving the environment, namely as a barrier to abrasion, a habitat for marine biota and natural resources. Mangroves in Botudidingga Tourism are spread along the coastline of Dambalo Village. The mangroves in North Gorontalalo are still beautiful and green, this is because the village government and the people of Dambalo Village have made various efforts to preserve mangroves, such as reforesting mangroves, issuing mangrove protection regulations, and increasing public awareness about the importance of mangroves. The research method is using the exploration method. The exploratory method can be carried out with a qualitative approach with the aim of understanding the phenomenon in depth. The definition focuses on research, place, population and samples/informants, main materials and tools, data collection techniques, and techniques. Researchers make direct observations and data is collected based on findings in the field.

Abstract

Abstract: An area of 11 hectares is Tutuwoto Village, North Gorontalo Regency, located there (KPH Gorut, 2010). Tutuwoto Village, Anggrek District, North Gorontalo Regency: The Mangrove Area was used as the location of this research. The three month period from April to June 2018 when this research was conducted. Crustacean samples were collected using simple fishing gear in the form of nets, nets and seser. Species abundance was calculated using the formula Odum, (1996). Calculation of diversity using the formula (Sannon-Wienner). The composition of the crustaceans numbered 110 individuals, consisting of 7 species, Scylla serrata 15 individuals, Scylla olivacea 14 individuals, Scylla tranquebarica 13 individuals, Carcinus maenas 14 individuals, Metapenaeus elegans 19 individuals, Penaeus latisulcatus, 20 individuals and Metapenaeus affinis 15 individuals. Based on the ODUM standard, the crustacean diversity values at the study sites ranged from 1.10 to 1.39. In 1993, the crustaceans at the study site were classified as medium because the value of 1H' was 3. With a value of 37.04%, Penaeus latisulcatus had the greatest abundance, and 26.79% of the family Portunidae dominated Scylla serrata. Type Many crustaceans are in the abundance category for all types according to Michael's criteria (1995) because the K value is more than 20. All locations generally have favorable environmental conditions for crustacean and mangrove life
