Abstract

Ikan tuna adalah jenis ikan dengan kandungan protein yang tinggi dan lemak yang rendah. Ikan tuna mengandung protein antara 22,6 - 26,2 g/100 g daging. Lemak antara 0,2 - 2,7 g/100 g daging. Di samping itu ikan tuna mengandung mineral, kalsium, fosfor, zat besi dan sodium, vitamin A (retinol), dan vitamin B (thiamin, riboflavin dan niasin). Salah satu pengolahan tradisional ikan tuna adalah pembuatan kerupuk ikan tuna, produk olahan ini sangat digemari oleh masyarakat. Karena memiliki nilai ekonomi, maka produk olahan ini perlu diteliti, untuk mengetahui total kepadatan koloni bakteri, mengetahui jenis-jenis bakteri pada kerupuk ikan tuna dan mengetahui cita rasa kerupuk tuna dengan metode uji organoleptik, yaitu tekstur, aroma, warna dan rasa. Penelitian ini menggunakan metode eksporatif, dengan teknik pengambilan sampel dilakukan secara langsung pada tempat pengolahan yaitu di Kelurahan Toboko dan Akehuda Kota Ternate. Hasil  penelitian  menunjukan  bahwa jumlah total koloni bakteri tertinggi adalah 3.1 × 103 CFU/gram pada sampel A dan adalah 0.5 × 106 CFU/gram pada sampel A dan B. Hasil indentifikasi bakteri ditemukan 3 (tiga) jenis Microccus, Bacillus, dan Stapylococcus. Sedangkan rata-rata hasil analisis organoleptik adalah; warna 1-9, aroma 6.52-7.79, tekstur 7.63 dan rasa adalah 7.41-8.11.

Abstract

Red algae (Rhodophyta) are low-level plants that generally grow attached to certain substrates such as coral, mud, sand, rocks and other massive objects. This type of algae take nutrients from the substrate by diffusion through the walls from its thallus. This alga prefers habitat of clear waters that have substrate base of coral, dead coral, volcanic rocks or massive objects. Red algae can be found in intertidal, subtidal to coastal areas with strong waves and currents as well as in mangrove area. This study aims to determine the diversity and distribution patterns and associations of red algae in seagrass ecosystems and coastal coral reefs of Ternate Island. The method used in this study is a descriptive method with sampling by line-transect quadrat (1x1 meter). The sampling locations were divided into three stations. Data were analyzed descriptively and the number of red algae (Rhodophyta) found at each station was included in a distribution map based on depth and density index. The results showed that the total number of individuals found at the three stations was 33, where ST II dominated with 12 with an average of 3 individuals per depth. Distribution of individuals per depth at ST II was highest at a depth of 10 m with 4 individuals, followed by a depth of 5 and 15 m each with 3 individuals, a depth of 25 m was 1 individual, and no individual was found at 20 m depth. Substrate type at a depth of 10 m was dominated by coral and sandy fractures that could support well the growth and development of red algae.  Alga merah (Rhodophyta) merupakan tumbuhan tingkat rendah yang umumnya tumbuh melekat pada substrat tertentu seperti pada karang, lumpur, pasir, batu dan benda keras lainnya. Salah satu alga yang penting untuk diteliti adalah alga merah (Rhodophyta). Jenis alga ini mengambil nutrisi dari substrat secara difusi melalui dinding thallus-nya sedangkan habitatnya adalah perairan jernih yang mempunyai substrat dasar batu karang, batuan vulkanik dan benda-benda yang bersifat massive yang berada di dasar perairan. Alga merah dapat ditemukan pada daerah intertidal, subtidal sampai daerah tubir dengan ombak besar dan arus deras serta di hutan mangrove. Penelitian ini bertujuan untuk mengetahui diversitas dan pola sebaran serta asosiasi alga merah pada ekosistem lamun dan terumbu karang pesisir Pulau Ternate. Metode yang digunakan pada penelitian ini adalah metode deskriptif dengan pengambilan sampel secara line transek kuadrat (1x1 meter). Lokasi pengambilan sampel dibedakan menjadi tiga stasiun. Data dianalisis secara deskriptif dan jumlah alga merah (Rhodophyta) yang ditemukan pada setiap stasiun di tuangkan dalam peta distribusi berdasarkan data kedalaman serta indeks kepadatannya.  Hasil penelitian menunjukkan bahwa total individu yang ditemukan pada ketiga stasiun adalah sebanyak 33, dimana pada ST II mendominasi dengan jumlah 12 dengan rata-rata perkedalaman adalah 3 individu. Sebaran individu perkedalaman ST II terbanyak pada kedalaman 10 m sebanyak 4 individu, diikuti kedalaman 5 dan 15 m masing-masing adalah 3 individu, kedalaman 25 m sebanyak 1 individu, sedangkan pada kedalaman 20 m tidak ditemukan. Tipe pada kedalam 10 m didominasi oleh patahan karang dan berpasir dimana pada kondisi substrat tersebut dapat mendukung pertumbuhan dan perkembangan alga merah.

Abstract

Lindur mangrove fruit (Bruguiera gymnorrhiza) which is traditionally processed into cakes, cakes, mixed with rice, or eaten directly. Food sourced from the Coastal Ecosystem, namely the mangrove fruit of the Lindur type (Bruguiera gymnorrhiza) contains energy and carbohydrates that are pretty high, even surpassing the various types of food sources of carbohydrates commonly consumed by the community such as rice, cassava corn, or sago. The study aims to provide food-making training on Maitara Island, North Tidose District, Tidore Islands City. The service method used is Counseling and Training and Courses in food processing from Lindur fruit. The results showed that Lindur fruit has an average length of 27 cm with an average weight of 45 g. The results of the chemical analysis of lindur fruit were 73.756% water content, 1.246% fat content, 1.128% protein, 23.528% carbohydrates, and 0.342% ash content. The anti-nutritional content of HCN is 6.8559 mg and tannin is 34.105 mg. The manufacturing process consists of several stages, namely collecting mangrove fruit, handling mangrove fruit in the form of peeling, soaking then steaming and grinding to become flour to making various types of snacks from mangrove fruit, namely mangrove fruit fritters and mangrove fruit crackers. Dissemination of the importance of mangrove ecosystems regarding the biological functions of mangrove ecosystems and the process of utilizing mangrove ecosystems.

Abstract

Mangrove Forest ecosystems have distinctive characteristics and forms and have functions and benefits as development resources both as economic resources and ecological resources that have long been felt by the Indonesian people, especially for the people who live around that area. This research aims to identify the types of utilization of mangrove forest ecosystems and to analyze the total economic value of mangrove forest ecosystems in the area of Waidoba Island, South Kayoa District, South Halmahera Regency. The sampling method in this study used a purposive sampling method. Based on the results identification of the benefits and functions of the mangrove forest ecosystem in Waidoba Island area, Kayoa Selatan District, that there were (4) four types of mangrove forest ecosystem benefits, namely (1) direct benefits (2) indirect benefits, (3) optional benefits and (4) benefits of existence. While the results of costs and benefits of the total economic value of mangrove forest ecosystem in Waidoba Island area of South Kayoa District were obtained Rp. Rp.170.520.720.104/year or Rp.418.014.659,-/ha/year. This total economic value was the benefit value of mangrove forest ecosystem that utilized by the community covering an area of 407.93 Ha.
