Abstract

The purpose of this study was to determine the type and diversity of macrobenthos that inhabit the aggregation of Septifer bilocularis shellfish in the coastal waters of Tiwoho, North Minahasa Regency, North Sulawesi. Sampling of macrobenthos was carried out using core (PVC), both at the position of small aggregation (AK), middle large aggregation (ABT), and large edge aggregation (ABP). Sampling was carried out 4 times on different aggregations of shellfish. The data has been analyzed using the Diversity Index (H), the dominance index (D), and the Uniformity Index (E). It was identified that there were 25 types of macrobenthos occupying all aggregations of septifer bilocularis shells, which came from 11 classes including Gastropods, Bivalves, Malacostraca, Florideiphyceae, Ulvophyceae Ophiuroidea, Clitelatta, Maxillopoda, Globothalamea, Tubothalamea and Phaeophyceae. Biota diversity index varies from 1.60 – 1.70 which indicates that the biota in each aggregation has moderate diversity. The uniformity index value also varied, namely 0.069 for macrobenthos occupying the small aggregation (AK), then 0.066 in the middle large aggregation (ABT) and 0.064 in the large margin aggregation (GBP), which indicates the low uniformity of the macrobenthos in each aggregation. The dominance index of all aggregations was obtained between 0.27 - 0.36, which indicates that there is no species dominance for macrobenthos occupying different shellfish aggregations.Keywords: Diversity, Macrobenthos, Septifer bilocularis, Tiwoho

Abstract

The information about mangrove forest community structure in Tapuang village has never been reported. The location of the mangrove forest in this village is near  to the settlements. Three line transects with 50 m distance were laid perpendicular to the shore. In each line transect, 5 quadrants (10 x 10 m2) were established. The data were analyzed using several parameters density, frequency, dominance, important index value and diversity. This study found 5 mangrove species namely Avicennia marina, Sonneratia alba, Sonneratia ovata, Rhizophora stylosa and Nypa fruticans. Avicennia marina was the most species found in each transects and had the highest density, frequency, and dominance values.  The highest important value index (INP) was found in  Avicennia marina  in transect 2 with a INP value 183.80. Mangrove species diversity index for tree category in each transect was low (H'≤1) ranges from 0.99.Key Words: Tapuang Village, Mangrove, Community Structure

Abstract

Mangrove forests have a role as an absorber of carbon dioxide (CO2) from air and sea therefore they play an important role in mitigating climate change. The problems that exist today are the decline in the area of mangrove forests due to the conversion of land functions into ponds, and development in coastal areas. Decrease of mangrove forest areas can lead to reduced its ability to absorb and storage carbon dioxide (CO2). The purposes of this study were to analyze litter carbon content of mangrove leaf litter in the mangrove forest of Pontoh Village, Wori District, North Minahasa Regency and estimate the carbon content (C) in mangrove litter per hectare per year. Based on the results of the analysis, the total average percentage of carbon content in mangrove litter in Ponto Village, Wori District, North Minahasa Regency was 29.71% C/day, and from the estimation results, the average carbon content (C) in mangrove litter is 3.68 tons/ha/year. Key Word: mangrove, litter, carbon content ABSTRAK Hutan mangrove memiliki peran sebagai penyerap karbondioksida (CO2) dari udara sehingga berperan penting untuk mitigasi perubahan iklim. Permasalahan yang ada saat ini yaitu berkurangnya luas kawasan hutan mangrove akibat pengalihan fungsi lahan menjadi tambak, dan pembangunan di kawasan pesisir. Apabila berkurangnya kawasan hutan mangrove maka dapat menyebabkan berkurangnya sumber penyerapan dan penyimpanan karbodioksida (CO2). Adapun tujuan dari penelitian ini yaitu untuk menganalisis kandungan karbon pada serasah daun mangrove hutan mangrove Desa Lansa, Kecamatan Wori, Kabupaten Minahasa Utara dan mengestimasi Kandungan Karbon (C) pada serasah mangrove per luasan hektar per tahun. Berdasarkan hasil analisis didapatkan total rata-rata persentase kandungan karbon serasah mangrove di Desa Ponto, Kecamatan Wori, Kabupaten Minahasa Utara yakni sebesar 29,71% C/hari, serta dari hasil estimasi didapatkan rata-rata kandungan karbon (C) pada serasah mangrove sebesar 3,68 ton/ha/tahun.

Abstract

Seagrasses are flowering plants (Angiosperms) that are fully adapted to aquatic environments. Seagrasses are capable of living in salt water; even though it is immersed in salty water, it still functionsnormally. The function and role of seagrasses depend on the number of leaf blades, leaf length, leafwidth, and total biomass, all of which are highly determined by local conditions. This research wasconducted in Southeast Minahasa Regency in Pantai Borgo Village, Belang District and Beach Villageof Basaan I, Ratatotok District. This study aims to measure the morphometrics and meristics of seagrassspecies Enhalus acoroides, Thalassia hemprichii and Syringodium isoetifolium. Sampling of seagrasswas carried out using the cruising survey method, as many as 10 individuals for each species at eachstudy location, samples were taken using a knife and washed and put into plastic samples. Thenmeasured using a caliper ruler. The results obtained from the three seagrass species Enhalusacoroides, Thalassia hemprichii and Syringodium isoetifolium are different in morphometric and meristicsizes of the three seagrasses which are larger in Basaan I Beach compared to those in Borgo Beach.This is because in Borgo Beach there are many human activities that greatly affect the activity ofmorphometric and meristic sizes which in turn also affect the growth of seagrass. This difference isthought to be due to the high activity of the people who live around Borgo beach in the form of householdwaste disposal and fishing activities, namely the intensity of boat traffic and boat moorings, while onPasir Panjang Beach, Basan I Village is far from residential areas and is a tourist area that is not yetvery touristy. Stout is known by many people so it is still in good condition and maintained. Measurementof environmental parameters of the waters of Borgo Village Beach and Basaan I Village Beach are stillin optimum conditions for seagrass plants and development.

Lamun mampu hidup di air asin; meski terbenam dalam air asin lamun tetapberfungsi normal. Fungsi dan peranan lamun, bergantung pada jumlah helaian daun, panjang daun,lebar daun, serta biomassa total, yang kesemuanya itu sangat ditentukan kondisi setempat. Penelitianini dilakukan di Kabupaten Minahasa Tenggara di Pantai Desa Borgo Kecamatan Belang dan PantaiDesa Basaan I Kecamatan Ratatotok. Penelitin ini bertujuan untuk mengukur morfometrik dan meristiklamun jenis Enhalus acoroides, Thalassia hemprichii dan Syringodium isoetifolium. Pengambilansampel lamun dilakukan dengan menggunakan metode survei jelajah, sebanyak 10 individu untukmasing-masing jenis di setiap lokasi penelitian, sampel diambil dengan mengunakan pisau dicuci dandimasukkan kedalam plastik sampel. Kemudian diukur dengan menggunakan mistar kaliper. Hasil yangdiperoleh dari ketiga lamun jenis Enhalus acoroides, Thalassia hemprichii dan Syringodium isoetifoliumadalah berbeda ukuran morfomertik dan meristik dari ketiga lamun tersebut lebih besar yang berada diPantai Basaan I dibandingkan dengan yang ada di Pantai Borgo. Hal ini di karenakan di Pantai Borgobanyak terjadi aktivitas manusia yang sangat mempegaruhi aktivitas ukuran morfometrik dan meristik yang akhirnya juga berpengaruh pada pertumbuhan lamun. Perbedaan ini diduga karena tingginyaaktifitas penduduk yang bermukim disekitar pantai Borgo berupa pembuangan limbah rumah tanggaserta aktivitas kegiatan perikanan yaitu intensitas lalu lalang perahu serta tempat tambatan perahu,sedangkan di Pantai pasir panjang Desa Basan I jauh dari pemukiman warga dan merupakan daerahwisata yang belum terlalu bayak diketahui oleh banyak orang sehingga masih memiliki kondisi yangbaik dan terjaga. Pengukuran parameter lingkungan perairan Pantai Desa Borgo dan Pantai DesaBasaan I masih dalam kondisi yang optimum bagi tumbuhan dan perkembangan lamun.
