Abstract

This study aims to determine the relation of length-weight and growth of mangrove crabs (Scylla serrata) in the Mootilango Village, Duhiadaa Sub-district, Pohuwato Regency. This research was conducted by observation for ± 6 months starting from September 2015 until February 2016. The sampling area covers all of Duhiadaa Sub-district mangrove forest with random sampling method. The result of the research shows that the relationship between carapace length and weight of mangrove crab (Scylla serrata) has the equation W = 6,026L2,444 with correlation (R2) = 0,850. Crab population consist of three age group (L1 = 61,66666667cm, L2 = 17,81981982, and L3 = 0,176691729 cm). While the maximum carapace length (L∞) reach 17.204 cm with a growth rate coefficient of 0.2133 per year. Keywords: length; weight; growth; mangrove crab; Scylla serrata

Abstract

Remote sensing satellite imagery data can be used to monitor the condition of the lake, especially the lake area at certain times, especially the extent of Lake Limboto. The purpose of this research is to know the area of Limboto Lake using Landsat-OLI 2015 satellite image data. The research method used is image data processing which includes image cutting, image reinforcement, RGB color composite (R = NIR + SWIR, G = NIR, B = NIR-Red), and the image classification is done by digitizing directly on the screen (on screening digitizing) by considering the presence of water vegetation. Furthermore, data analysis is done by calculating the extent of Lake Limboto on the image of classification results. The results showed that the area of Lake Limboto in 2015 was 2,943 hectares. Keywords: spatial analysis; lake; Limboto Lake.

Abstract

This study aims to determine the effect of different substrates on egg hatchability and survival of carp (Cyprinus carpio) seeds. This research is an experiment with 4 treatments and 3 replications. The treatment of addition of substrate is A (Fibers), B (Hydrilla), C (Raffia String), D (Control) Treatment. The design used is a Completely Randomized Design (CRD) using Analysis of Variance (ANOVA). Furthermore, further tests are carried out using the Least Significant Difference Test (LSD). The results obtained indicate that each treatment has a very significant effect. The highest hatchability was found in the palm substrate treatment of 87.66%, followed by the treatment of the raffia substrate 78.42%, then the control treatment with the percentage of hatching power was 64.78% and the lowest was in the hydrilla substrate treatment with the hatchability percentage of 57.51%. While the highest survival rate of tilapia fish was found in the treatment of palm oil substrate by 73.67%, and the survival rate with the lowest percentage was in the treatment of hydrilla sp. Substrate.

The research was conducted in February to July 2016. The research method was observation and interviews with the community as respondents regarding the costs of damage and the construction of wave barriers. Observations were also made on the impact of losses due to loss of residence, land damage and damage to housing. The results showed that the indirect benefit value of wave and current barrier was IDR. 255,414,000 / year. The types of ownership losses due to abrasion are loss of residence (averagely IDR. 28,928,000,-) the loss on damage to land is averagely IDR 3,396,250,- and the loss on damage to dwelling place averagely IDR. 2,939,833,-.

Abstract

The purpose of this study is to determine Escherichia coli bacterial content in chunks of yellowfin tuna (Thunnus albacores) sold in Central Market Gorontalo. This study uses descriptive analysis method which gives an idea as carefully as possible about an individual, state, symptom, or a particular group. Based on observations of the total MPN Coliform samples A, B and C have MPN coliform exceed ISO standards for quality and food safety requirements of fresh fish, ie 24.00 MPN / g. Test EMBA (Eosin Methylene Blue Agar (EMBA) indicates that the Tuna Yellowfin positive for the bacterium Escherichia coli with colors that are characterized by green metalic. Pieces of tuna sold in the central market town Gorontalo safe to eat at 08:00 am, while at 10:00 am and 12:00 am bacterial content becomes a lot more. The longer the fish are displayed at table without any effort to maintain the quality of the fish, the more the bacteria contained in the fish.

Abstract

Penelitian secara khusus bertujuan mengidentifikasi proses akresi dan abrasi sepanjang kawasan pesisir Selatan Provinsi Gorontalo melalui pemetaan dan analisis laju perubahan garis pantai rentang 14 tahun menggunakan teknik sistim informasi geografis pada hasil ekstraksi fitur garis pantai kawasan pesisir Selatan Gorontalo secara spasial temporal menggunakan teknik penginderaan jauh pada dataset citra Landsat tahun 2001 dan tahun 2015. Hasil penelitian menunjukkan bahwa panjang garis pantai Selatan Gorontalo tanpa mengikut-sertakan panjang garis pantai pulau-pulau yang terpisah dari daratan berturut-turut adalah sepanjang 444.28 km tahun 2001 dan 435.25 km tahun 2015 sehingga terdapat fenomena pengurangan garis pantai sepanjang 9.03 km dalam rentang 14 tahun. Intensitas proses akresi dan abrasi berjalan secara bersamaan sepanjang rentang 14 tahun di mana pertumbuhan delta muara sungai di Desa Manawa Kecamatan Patilanggio Kabupaten Pohuwato sangat signifikan menyumbang 58.04% secara keseluruhan luas akresi di pesisir selatan Gorontalo yang berlangsung selama 14 tahun. Baik proses akresi maupun abrasi intensitas lokasinya berkorelasi dengan jenis-jenis tutupan/penggunaan lahan. Korelasi positif mutlak (r=1) pada kedua proses terdapat pada jenis tutupan rawa. Proses akresi yang menjadi proses mendominasi kestabilan sepanjang kawasan pesisir Selatan Gorontalo berkorelasi positif berturut-turut dengan jenis tutupan hutan bakau (r=0.94) dan hutan rawa (r=0.91). Adapun proses abrasi berkorelasi positif signifikan dengan jenis tutupan lahan tambak (r=0.90). Informasi yang diperoleh dari penelitian ini mengindikasikan pentingnya monitoring dan penelitian lanjut yang focus dan detil baik dalam hal dinamika spasial-temporal secara lokal kaitannya dengan jenis dan pola perubahan tutupan lahan, maupun terkait kombinasi penggunaan dataset beresolusi lebih tinggi dalam kajian-kajian ke depan yang relevan dalam rangka pengelolaan kawasan pesisir selatan Gorontalo.
