Abstract

Macroalgae are chlorophyll plants, consisting of thallus and can live in polluted waters. The purpose of the study was to analyze the lead metal (Pb) in the water column and thallus red algae Kappaphycus alvarezii which was cultivated in a certain period of time in the waters of Totok Bay. The cultivation method used is the bottom method. The algae weight is measured every two weeks. Water quality parameters and lead metal analysis (PB) are carried out in the Baristan laboratory. The results obtained are algae can grow according to the time period. Water quality can affect algae growth. Lead metal content in water is detected high enough as well as in thallus algae in the 3rd week. Keywords : Kappaphycus alvarezii, Lead metal, Water quality, Totok Bay Makroalga merupakan tumbuhan yang berklorofil dan tubuhnya berupa thallus serta mampu hidup pada perairan tersemar. Penelitian ini dilakukan dengan tujuan untuk menganalisis kandungan logam timbal (Pb) dalam air dan thallus alga merah Kappaphycus alvarezii yang dibudidayakan dalam periode waktu tertentu di perairan Teluk Totok. Metode budidaya pada yang digunakan adalah metode lepas dasar (bottom method). Pengukuran berat alga dilakukan setiap dua minggu. Beberapa parameter kualitas air dan analisis logam timbal (Pb) dilakukan di Laboratorium Baristan. Hasil yang diperoleh yaitu alga dapat tumbuh sesuai dengan periode waktu. Kualitas air dapat mempengaruhi pertumbuhan alga.Kandungan logam timbale pada air terdeteksi cukup tinggi demikian juga pada thallus alga di minggu ke-3. Kata kunci : Kappaphycus alvarezii, Logam Timbal, Kualitas air, Teluk Totok

Abstract

Culture pattern of  seaweed Kappaphycus alvarezii like cultivation calender will improve the quality dan increase productionof seaweed.  This pattern can be arranged through examining seaweed growth and measuring waters quality. Culture technique used was long line where seaweed was tied at 100 cm from water surface.  Cultivation cycle was done twice a year using five frames measuring 3 x 3 x 2 m3 each and located at five observation stations.  Biophysical of water at each station was measured. Data of biophysic and seaweed growth were measured every two weeks for three months (from July to October 2013).  The present of epiphytes and ice-ice and seaweed pests was also observed.  Research result found the best season for cultivating seaweed at Nain Island was from July to early September while the evidence of ice-ice was high from September to October.  Biophysic and water quality around Nain Island was suitable of the growth of K. Alvarezii.   Keywords: seaweed, cultivation calender, growth, waters condition, ice-ice

Abstract

The aimed of research was to identify and analyze the natural resources potential for mariculture development in Regency of Sangihe Archipelago. This research was carried out at Talengen waters in Central  Tabukan District and Manalu waters in South Tabukan District.  Research method was survey and the data was analyzed descriptively.   Primary data to be collected included water quality and socio economic data.  The second was obtained through interview to respondent chosen randomly.  Questionnaire was also used in collecting data.  Research result  showed that water quality at Talengen and Manalu waters was optimal and thus feasible for mariculture. However,  the development of mariculture at these locations should consider other utilization whether for fishery, ecotourism and conservation. Keywords:  mariculture, water quality, Talengen Waters, Manalu Waters

Abstract

The study aimed to determine the growth of seaweed Kappaphycus alvarezii cultured using different type of rope ris with different conditions. The study was conducted over 64 days, starting on September 1 to November 3, 2014 Village Jaya Karsa, North Minahasa Regency, North Sulawesi. The experiment was designed according to 2x3 factorial experiment in a completely randomized design (CRD). Two factors were tested, namely rope ris type and conditions. Factors ris types strap consisted of two type: Monofilament nylon and Multifilament PE. Factor conditions of ris rope consisted of three levels, namely: new, used cleaned, and the former was not cleaned, so there were 6 treatments. Experiment container was floating longlines. One unit consisted of 3 longline trial. Length per longline 28.80 m, 18 pieces of string length of rope ris 1.6 m each strap was 7 point planting, planting the overall number of points 378 points planting. K. alvarezii seaweed seedlings obtained from Jaya Karsa farmers. Weighing was done 4 times, weighing early, 1 week, 2 weeks, and at the end of week 3, using a digital scale with a precision of 1 g. Accretion weight was calculated to be the absolute growth rate (g) and daily growth rate (%). The results showed that the absolute growth and the daily growth of seaweed K. alvarezii not significantly influenced by different type and condition of the rope ris. Keywords : Kappaphycus alvarezii, long line, Multifilament PE, Monofilament nylon.

Abstract

A research had been conducted to evaluate seaweed and waters condition at seaweed  culture area at Jayakarsa Village.  Research locations were divided into three station: 1) at former culture area near mangrove area and the beach, 2)  at active culture area, 3) at former culture area with sandy bottom and ?lamun? field.  Water quality measured included temperature, salinity, pH, DO, turbidity, flow rate, water depth, bottom type. Protectivenss, risk, and accesibility were also observed. Data was analyzed descriptively and then compared to standard value established in Kangkan (2006).  Water condition at station 1 and 2 was categorized Grade 2 (moderately suitable) while at station 3 was marginally suitable which was categorized Grade 3. Major problems faced by the farmers was ice-ice disease, silt and epiphytes that could reduce the production.   Keywords: Kappaphycus alvarezii, water quality, Jayakarsa Village, moderately suitable, marginally suitable

Abstract

The success of seaweed cultivation is determined from the determination of the location. This is because the production and quality seaweed influenced by ecological factors including the condition of the substrate surface waters, water quality, climate, geographical bottom waters. Arakan villages in the District of South Minahasa regency become one of the centers of seaweed cultivation in the province of North Sulawesi. The specific objective of this study was obtained in the form of a map of suitability mapping seaweed cultivation areas; gathering data and information about the extent of the area, water capacity, area unit, and carrying water. The study was conducted in the waters of the village of Arakan, District Tatapaan, South Minahasa regency, North Sulawesi. When phase 3 study conducted every month from June to December in 2012. The analysis is based on space availability, suitability waters that support the cultivation of seaweed. Suitability space spatially waters using physical and chemical parameters of waters which is a prerequisite eligibility seaweed cultivation. Spatial observations by using a Geographic Information System (GIS) for the weights and scores in determining the suitability of land. Process is done through the preparation of spatial database and
