Abstrak. Penelitian ini bertujuan untuk mengetahui karakteristik habitat dan pola pertumbuhan kepiting kelapa (Birgus latro) di Takome Pulau Ternate dan Idamdehe Kecamatan Jailolo Propinsi Maluku Utara. Penelitian ini dilaksanakan pada bulan April-Juli 2014. Data yang dikumpulkan adalah tekstur substrat dengan metode pipet, penentuan kandungan nitrat danfosfat tanah dengan metode spektofotometer, pengukuran panjang + rostrum (cp+r) kepiting kelapa dan pola pertumbuhannya. Selain it juga diukur suhu udara, suhu lubang dan kelembaban udara. Hasil penelitian menunjukkan bahwa Idamdehe memiliki karakteristik pantai yang curam, bahkan di beberapa lokasi penangkapan sangat terjal, sedangkan di lokasi Takome Pulau Ternate memiliki karakteristik pantai yang lebih landai. Tekstur substrat di lokasi Takome Pulau Ternate terdiri atas pasir (55,76 %), debu (18,4%) dan liat (25,84%) dan Stasiun Idamdehe memiliki tekstur pasir (49,17%), debu (25,61%) dan liat (25,22%)dankandungan bahan organik substrat (Total N) di Takome adalah 0,31% dan total P adalah 0,09% sedangkan di Idamdehe Total N adalah 0,19% dan Total P 0,02%. Suhu udara di lokasi Idamdehe berkisar 26-280C dan di Takome 27-280C. Kelembaban udara 73%-98% di Idamdehe dan 71%-90% di Takome. Parameter lingkungan berupa suhu udara, kelembaban udara, tekstur substrat dan kandungan bahan organik di kedua lokasi penelitian mendukung kehidupan kepiting kelapa di habitat alaminya. Pola pertumbuhan kepiting kelapa di kedua lokasi Idamdehe adalah allometrik negatif.Kata kunci: Karakteristik habitat, Idamdehe, Takome, Birgus latro, isometrik, allometrik negatifAbstract. This objectives of the present study were to evaluate the habitat characteristics and growth patterns of the coconut crabs in Takome and Idamdehe waters North Maluku Province. This study was conducted during April-July 2014. The collected data were the substrate texture, nitrate and phosphate contents of soil using spectrophotometric method, length + rostrum (cp+r) of coconut crabs and the growth patterns. In addition, the air temperature, hole temperature and humidity were also recorded during the study. The results showed that Idamdehe waters has precipitous coast, indeed very precipitous in several catching locations, while Takome waters in Ternate Island has sloping coast. The substrate texture of Takome waters in Ternate Island consisted of sands (55.76%), dusts (18.4%) and clays (25.84%), while Idamdehe waters has the substrate texture that consisted of sands (49.17%), dusts (25.61 %) and clays (25.22%). As for organic matter contents of the substrate, Takome waters has 0.31% in total N and 0.09% in total P, while Idamdehe waters has 0.19% in total N and 0.02 % in total P. The air temperature in Idamdehe waters ranged between 26-280C and in Takome waters ranged between 27-280C. Air humidity in Idamdehe waters was 73%-98% and in Takome waters was 71%-90%. The environmental parameters such as temperature, humidity, substrate texture and organic matter content in both locations are suitable for coconut crab growing. The growth pattern of coconut crabs in Idamdehe and Sulamadaha waters were allometric negative pattern.Keywords: Habitat characteristics, Idamdehe, Takome, Birgus latro, isometric, negative allometric.

Coconut crabs (Birgus latro) is a fishery resource that is only found in eastern Indonesia, and the waters of Ternate City are an area that has this potential. This research aims to determine the size distribution and habitat characteristics of coconut crabs in Tomajiko, Hiri Island District. The data collection method consists of several stages, namely determining stations, distributing bait, catching coconut crabs, morphometric measurements, and observing environmental parameters. Determination of stations in this study was carried out based on topographic differences in Tomajiko (divided into two stations). Coconut crab catching uses the roaming survey method. The bait used is coconut meat that has been split into several parts and coconut meat that has been mashed. The morphometric dimensions measured were chest length (carapace length) and body weight. The habitat characteristics observed were the type and extent of vegetation, organic matter content and substrate texture, environmental parameter measurements (soil temperature, air humidity and soil pH). The results of the research showed that the coconut crabs caught at both stations had relatively the same length, but the largest weight was found at station 2. Habitat characteristics in Tomajiko, Hiri Island strongly support the survival of coconut crabs.

Water quality and trophic status of waters play an important role in aquaculture activities because they will affect the growth process of cultivated fish, if the water quality and trophic status are low then they can support aquaculture activities in the waters of Laguna Lake, South Ternate City. The purpose of this study was to determine the water quality and trophic status in the waters of Laguna Lake in supporting and supporting freshwater aquaculture activities. The research method used in this research is descriptive qualitative, the results of air analysis are described based on Class and Water Quality Standards, while the trophic status is estimated based on Carlson, 1977. The results of the analysis show that the water quality in Laguna Lake is still in accordance with Class II Quality Standards. PP No. 22 of 2021, while the trophic level status in Laguna Lake is also classified in the oligotrophic category, namely TSI <40, TSI in Laguna Lake waters ranges from 20.69-23.28. Based on the results of the analysis of water quality and trophic status, it was found that the waters of Laguna Lake are still good and can support freshwater fish farming activities
