Abstract

Tiram mutiara merupakan salah satu biota laut yang tergolong memiliki nilai jual yang relatif tinggi sehingga banyak di budidayakan oleh para pembudidaya di Indonesia, Budidaya tiram mutiara memiliki potensi yang besar tidak terlepas dari faktor keberhasilan budidaya yaitu pemilihan kedalaman yang tepat. Penelitian ini dilakukan untuk mengetahui pengaruh perbedaan kedalaman terhadap pertumbuhan dan kelangsungan hidup tiram mutiara jenis Pinctada maxima yang dibudidaya di Balai Perikanan Budidaya Laut Lombok. Penelitian ini menggunakan rancangan acak lengkap dengan tiga perlakuan kedalaman, yaitu 2 m, 4 m, dan 6 m, Hasil Penelitian menunjukan bahwa rentang kedalaman terhadap pertumbuhan tiram mutiara yang diteliti selama tiga bulan, tidak berpengaruh nyata terhadap pertumbuhan panjang mutlak, laju pertumbuhan spesifik, dan kelangsungan hidup anakan tiram mutiara. Adapun hasil pengamatan kualitas air yang dilakukan dimana tiram mutiara dapat hidup pada suhu 27,1 °C – 28 °C, salinitas 30 – 35 ppt dan pH 8 – 8,3.Kata kunci : Tiram mutiara, Pertumbuhan, Sintasan, Anakan, Kedalaman

Abstract

This study aims to analyze the added value resulting from processing Kappaphycus sp seaweed into Alkaline Treated Cottonii (ATC) and to evaluate the economic aspects of the process. The ATC processing process is carried out through boiling seaweed with a solution of potassium hydroxide (KOH) at a temperature of 80–85°C for two hours, followed by washing, cutting, and drying. The results of the study showed that the processing of dried seaweed into ATC produced an added value of Rp 67,000 per kilogram of dried seaweed, with a total added value for 100 kg of seaweed reaching Rp 7,210,000. This added value reflects a significant increase in the selling price of processed products compared to the sale of seaweed in raw form. Financial analysis showed a gross profit of IDR 5,900,000, with a break-even point reached in the production of around 28.45 kg of ATC. This study concludes that processing seaweed into ATC not only increases the economic value of the product, but also opens up opportunities for product diversification such as pure carrageenan which is in great demand in the international market. Therefore, processing seaweed into ATC can provide great economic benefits for coastal communities and can improve the welfare of business actors through the added value produced.

Abstract

This study aims to determine the effect of different stocking densities on the growth and survival of striped catfish (Pangasius sp.) fry reared in hapa net enclosures at the Central Fish Hatchery (BBIS) Noekele, Kupang Regency. The study employed a Completely Randomized Design (CRD) with three different stocking densities: 90, 120, and 150 fish per hapa, each replicated three times. The observed parameters included survival rate, absolute weight gain, absolute length gain, and water quality (temperature, pH, dissolved oxygen, and ammonia). Data were analyzed using ANOVA to assess the significance of differences among treatments, followed by the Least Significant Difference (LSD) test if significant differences were found. The results showed that different stocking densities had a significant effect on the survival and growth of catfish fry. ANOVA results indicated that stocking density had a significant effect (p < 0.05) on survival rate, but not on absolute weight gain or absolute length gain. The density of 90 fish per hapa yielded the best results, with higher survival rates, weight gain, and length gain compared to the densities of 120 and 150 fish per hapa. This condition suggests that at lower densities, competition for oxygen, space, and feed is reduced, thereby supporting more optimal growth. Therefore, a stocking density of 90 fish per hapa is recommended as an effective cultivation strategy to enhance the performance of catfish fry in the region. Keywords: Cultivation of hapa, catfish, density, growth, survival rate

Abstract

Proper transportation of seaweed seeds is one effort to increase their productivity. Good transportation must be able to guarantee that seaweed seeds arrive at the location in healthy and fresh condition. The research aims to determine the effectiveness of compartment type transportation container design in maintaining the quality of Kappaphycus alvarezii seaweed seeds after transportation for 6 days. This research uses an experimental method with three treatments, namely transportation container design with treatment A with 4 circulation holes, treatment B with 6 circulation holes, and treatment C with 8 circulation holes. Seaweed seedlings were transported for 6 days, with temperature monitoring every 4 hours while ice cubes were replaced every 24 hours. Daily weight loss rates were analyzed using ANOVA while temperature fluctuations in the transportation container were analyzed descriptively. The research results show that using a compartment type transportation container can maintain the temperature in the optimal range, namely 20°C-28°C for ±24 hours and maintain the freshness of seaweed seeds for 6 days of transportation. The compartment type design also makes it easier to replace ice cubes during transportation, thereby extending the transportation distance.
