Abstract

Keberadaan vegetasi berupa pepohonan berperan dalam menjaga kestabilan ekosistem dan lingkungan. Pepohonan dikenal mampu menciptakan lingkungan yang bebas polusi dikarenakan pohon mampu menyerap gas polutan, menurunkan suhu dan menyerap bunyi melalui batang, ranting dan daun.  Tujuan penelitian ini untuk mengetahui efektivitas jenis pohon terhadap tingkat penyerapan bising yang disebabkan oleh kendaraan bermotor di Provinsi Gorontalo. Penelitian ini dilakukan di Kab. Bone Bolango ruas Jl. BJ. Habibie, Tapa-Kabila dan By Pass. Kota Gorontalo di ruas Jl. Pangeran Hidayat, HOS. Cokroaminoto dan HB. Jassin. Kab. Gorontalo Jl. Sama’un Pulubuhu, Sudirman, dan Trans Sulawesi. Tingkat kebisingan diukur menggunakan sound level meter. Tingkat kebisingan diukur pada 1 meter di depan pohon dan pada 1 meter dan 5 meter di belakang pohon, 1,5 m dari tanah. Mengumpulkan data pohon melalui metode survei dan mencatat ketebalan batang, tinggi batang bawah, tinggi tajuk, luas tajuk dan jarak tanam. Hasil Pengukuran menunjukkan bahwa efektivitas penyerapan bunyi oleh jenis pohon Trembesi (Samanea saman) berkisar 0.11% - 0.17% (pengurangan 7.3 dB - 16 dB). Pohon Angsana (Pterocarpus indicus) berkisar 0.07% - 0.14% (pengurangan 7.2 dB - 13.3 dB). Pohon Mahoni (Swietenia mahagoni) sebesar 0.06% - 0.16% (pengurangan 5.2 dB - 13.5 dB) dan pohon Kali Jawa (Lannea coromandelica) sebesar 0.08% - 0.15.% (pengurangan 6.3 dB – 11.9 dB). Berdasarkan kerapatan jarak tanam, luas tajuk, tinggi pohon dan diameter batang, setiap jenis pohon memiliki kemampuan menyerap suara yang berbeda. Pohon Trembesi memiliki efektivitas yang lebih besar dibanding jenis pohon Angsana, Mahoni ataupun Kalijawa. Hal ini karena Trembesi memiliki luas kanopi yang besar dan susunan daun yang rapat sehingga mampu menahan gelombang bunyi yang dihasilkan oleh kendaraan bermotor. ABSTRACTThe existence of vegetation such as trees plays an important role in maintaining the stability of ecosystem and environment. The potential of trees is also known to create a pollution-free environment because trees can absorb the pollutants, lower the temperature, and also absorb the sounds through the stems, branches, and leaves. The purpose of this research is to figure out the effectiveness of type of trees towards the level of absorbing the noise emitted by motor vehicles in Gorontalo Province. This research was conducted in Bone Bolango District on a road section of BJ. Habibie Street, Tapa-Kabila Street and a bypass. In Gorontalo City, the location of the research was in Pangeran Hidayat Street, HOS. Cokroaminoto Street and HB. Jassin Street. In Gorontalo District, the research was located in Sama’un Pulubuhu Street, Sudirman Street, and Trans Sulawesi. The noise level is measured by using sound level meter. The level of noise was measured on 1 meter in front of the trees, on the first and fifth meters behind the trees, and 1.5 meters above the ground. The data of the trees were collected from a survey method and note-taking on the thickness of the stem, height of the bottom stem, height of the canopy, area of the canopy, and the distance between plants. The measurement results showed that the effectiveness of sound absorption by Rain Tree (Samanea saman) is around 0.11% - 0.17% (7.3 dB - 16 dB subtraction); Angsana Tree (Pterocarpus indicus) around 0.07% - 0.14% (7.2 dB - 13.3 dB subtraction); Mahogany Tree (Swietenia mahagoni) as big as 0.06% - 0.16% (5.2 dB - 13.5 dB subtraction); and Kalijawa Tree (Lannea coromandelica) as big as 0.08% - 0.15.% (6.3 dB – 11.9 dB subtraction). Based on the spacing density of the plants, area of the canopy, height of tree and the stem diameter, each type of tree has different potential in absorbing sound. Rain tree has is more effective than Angsana, Mahogany, and Kalijawa Trees. This is because Rain Tree has a big area of canopy and tight leaf arrangement so that it can absorb the sound wave produced by motor vehicles.

Abstract

Hutan mangrove Langge yang terdapat di Kecamatan Anggrek Kabupaten Gorontalo Utara memiliki keunikan dari pola zonasi dan keanekaragaman jenis. Hal ini yang menjadikan hutan mangrove di kawasan tersebut sebagai objek wisata tracking mangrove yang dikenal dengan nama “mangrove in love. Hutan mangrove memiliki berbagai fungsi ekologis yang sangat kompleks yakni sebagai daerah pemijahan  (spawing ground), tempat asuhan (nursery ground), dan tempat mencari makan (feeding ground) biota laut yang beraneka jenis dan memiliki fungsi ekonomis diantaranya buah mangrove dapat diolah menjadi berbagai produk kue dan sumber pangan alternatif pengganti beras. Penelitian ini bertujuan untuk : 1) untuk mengetahui komposisi jenis mangrove asosiasi; 2) untuk mengetahui struktur komunitas dari hutan mangrove Langge; dan 3) nilai Indeks Keanekaragaman. Adapun metode yang digunakan dalam penelitian ini adalah metode jalur berpetak (kombinasi plot dan transek). Jumlah spesies yang ditemukan akan dilihat untuk menjadi dasar penentuan komposisi jenis. Untuk pengkuran struktur komunitas mangrove dengan melakukan perhitungan terhadap Kerapatan Relatif (KR) dan Frekuensi Relatif (FR). Selanjutnya data yang didapatkan ditabulasikan untuk memperoleh nilai Indeks Nilai Penting (INP). Perhitungan keanekaragaman jenis menggunakan rumus (Sannon-wienner). Hasil penelitian menemukan 12 spesies tumbuhan mangrove asosiasi yakni Acanthus spinosus, Chromolaena odorata, Crassocephalum sp, Calotropis gigantean, Ipomea pes-caprae, Ricinus communis Excoecaria agallocha, Scaevola taccada, Spinifex littoreus, Terminalia catappa, Derris trifoliate dan Nypa fruticans. Struktur komunitas menunjukkan Chromolaena odorata memiliki nilai INP sebesar 33,2%, Kerapatan Relatif sebesar 24,91%, dan Frekuensi Relatif sebesar 8,33%.  Spesies dengan nilai INP terendah dimiliki oleh Nypa fruticans yaitu sebesar 9,14%, Kerapatan Relatif sebesar 0,81%, dan Frekuensi Relatif sebesar 8,33%. Nilai Indeks Keanekaragaman (H’) mangrove asosiasi sebesar 2,175 dan termasuk dalam kriteria tingkat keanekaragaman sedang. Data yang diperoleh ini dapat digunakan dalam pengelolaan hutan mangrove di Gorontalo Utara serta dapat menjadi database dalam usaha konservasi mangrove guna mengurangi efek pemanasan global.Langge mangrove forest located in the District of North Gorontalo District Orchid has a uniqueness of zoning patterns and keanekragaman types. This is what makes the mangrove forests in the region as a tourist attraction tracking mangrove known as the "mangrove in love. Mangrove forests have a variety of ecological functions is very complex which is a spawning area (spawing ground), point of care (nursery grounds), and foraging (feeding ground) various types of marine life and has the economic function of which pieces of mangrove can be processed into various products cake and alternative food sources instead of rice. This study aims to: 1) to determine the association of mangrove species composition; 2) to determine the community structure of mangrove forests Langge; and 3) the value of diversity index. The method used in this study is a terraced path method (combination of plots and transects). The composition of the types of views based on the number of species found. For sizing mangrove community structure by calculating the Relative Density (KR) and Relative Frequency (FR). Then the data obtained are tabulated to get the value of Importance Value Index (IVI). Calculation of species diversity using the formula (Sannon-wienner). The study found an association of twelve species of mangrove plants and the relative dominance (DR), then the data obtained are tabulated to get the value of Importance Value Index (IVI). Calculation of species diversity using the formula (Sannon-wienner). The study found an association of eight species of mangrove plants and the relative dominance (DR), then the data obtained are tabulated to get the value of Importance Value Index (IVI). Calculation of species diversity using the formula (Sannon-wienner). The study found an association of twelve species of mangrove plantsnamely Acanthus spinosus, Chromolaena odorata, Crassocephalum sp, Calotropis gigantean, Ipomea pes-caprae, Ricinus communis Excoecaria agallocha, Scaevola taccada, Spinifex littoreus, Terminalia catappa, Derris trifoliate dan Nypa fruticans. Community structure showed Chromolaena odorata has a value of IVI of 33,2%, amounting to 24,91% Relative Density and Relative Frequency of 8,33%. The species with the lowest IVI owned by Nypa fruticans that is equal to 9,14%, 0,81% Relative Density and Relative Frequency of 8,33%. Values Diversity Index (H ') at 2.175 and mangrove associates included in the criteria for a medium level of diversity. The data obtained can be used in the management of mangrove forests in North Gorontalo and can be a database of mangrove conservation efforts to reduce the effects of global warming.
