Abstract

Penelitian ini bertujuan untuk mengetahui apakah ukuran kerang mutiara (Pinctada maxima) dapat berpengaruh terhadap tingkat keberhasilan insersi inti mutiara di perairan Kecamatan Kupang Barat. Penelitian ini menggunakan 100 sampel kerang mutiara (P. maxima) dengan ukuran panjang rata-rata 10,97 cm, lebar 11,63 cm, berat 5,9-9 gram serta tebal 1,7 cm. Penelitian ini dilaksanakan selama 3 bulan  di PT. Timor Otzuki Mutiara pada Perairan Kecamatan Kupang Barat. Metode yang digunakan dalam penelitian yaitu: metode partisipatif yaitu turun ke lapangan kegiatan budidaya (pembesaran) dan ikut terlibat langsung pada kegiatan pembesaran kerang mutiara. Hasil penelitian ini menunjukan bahwa keberhasilan insersi inti mutiara dapat berpengaruh terhadap ukuran panjang kerang mutiara. Hal tersebut dibuktikan dengan hasil analisis regresi linear berganda yang menunjukan bahwa nilai koefisien uji Thitung dari variabel (X1) panjang = 0,000 < 0,05 sehingga panjang kerang mutiara dapat berpengaruh terhadap tingkat keberhasilan insersi inti mutiara. Sedangkan pada ukuran lebar, tebal serta berat tidak berpengaruh terhadap tingkat keberhasilan insersi inti mutiara hal ini dibuktikan dengan uji Thitung yang menunjukan bahwa dari variabel (X2) lebar = 0,0179, (X3) berat = 0,953 dan (X4) tebal = 0,834  data tersebut > 0,05 yang artinya tidak berpengaruh terhadap tingkat keberhasilan insersi inti mutiara. Faktor yang mempengaruhi tingkat keberhasilan insersi inti mutiara dapat dipengaruhi oleh penyuntikan inti yang kurang tepat sehingga kerang mudah mengalami stres dan mati. Serta kerang yang memiliki ukuran kecil belum bisa melakukan proses penyuntikan inti karena ukuran gonad kerang masih kecil dan belum bisa menerima benda asing masuk dalam gonadnya.Kata Kunci : Kerang Mutiara, Ukuran, Insersi Inti Mutiara

Abstract

The pearl oyster (Pinctada maxima) is a high-value aquaculture commodity whose hatchery success is strongly influenced by environmental conditions, particularly temperature. This study aimed to determine the effect of different temperatures on the growth and survival rate of Pinctada maxima larvae. The research was conducted at PT Timur Otsuki Mutiara (PT. TOM), Kupang Regency, East Nusa Tenggara, using a Completely Randomized Design (CRD) consisting of three temperature treatments: A (28°C), B (29°C), and C (30°C), each with three replications. The observed parameters included survival rate, absolute growth, dorsal–ventral specific growth rate, anterior–posterior specific growth rate, and water quality. Data were analyzed using Analysis of Variance (ANOVA). The results showed that temperature had a significant effect (P<0.05) on the survival rate and specific growth rate of the larvae. The 28°C treatment produced the highest survival rate (22.44%), dorsal–ventral specific growth rate (4.97%), and anterior–posterior specific growth rate (5.13%). The highest absolute growth was also recorded at 28°C, reaching 121.67 µm; however, no significant differences were observed among treatments (P>0.05). Water quality parameters remained within the optimal range for larval rearing throughout the study. Based on the research results, it can be concluded that 28°C is the optimum temperature for supporting the growth and survival of Pinctada maxima larvae, whereas increasing the temperature up to 30°C tends to reduce larval performance.

Abstract

Tilapia (Oreochromis niloticus) is a freshwater fishery commodity that has high economic value and is widely cultivated in Indonesia. The success of tilapia cultivation is greatly influenced by the quality of feed, so it is necessary to innovate effective, economical, and environmentally friendly feed ingredients. One potential alternative is the use of dragon fruit peel (Hylocereus sp.) which contains bioactive compounds such as antioxidants, polyphenols, and fiber. This study aims to determine the effectiveness of adding dragon fruit peel to feed on the growth and survival of tilapia. The results of the study are expected to provide information on the use of agricultural waste as a feed additive that can increase the productivity of tilapia cultivation sustainably. This study was conducted by raising tilapia in an aquarium using 4 treatments and 3 replications of feeding: 0% dragon fruit peel extract, 5% dragon fruit peel extract, 10% dragon fruit peel extract, 15% dragon fruit peel extract for 56 days, fish weight measurements were carried out every 7 days. The results of the ANOVA test showed that the addition of dragon fruit peel affected the growth of weight and length of tilapia. The weight growth of tilapia fed 15% dragon fruit peel extract reached 7.3 grams, and the absolute length growth reached 40 cm. The weight growth of tilapia fed 0% dragon fruit peel extract reached 6.7 grams and the absolute length reached 2.1 cm. The weight growth of tilapia fed 10% dragon fruit peel extract reached 2.9 grams and the absolute length reached 3.4 cm. The growth of tilapia fed 5% dragon fruit peel extract reached 2.7 grams and the absolute length reached 4.3 cm Keywords: Tilapia feed, dragon fruit peel, growth

Abstract

This study aimed to analyze the economic performance of Kappaphycus alvarezii seaweed farming in Tablolong Village and Oenaek Village, Kupang Regency, East Nusa Tenggara, Indonesia. Kappaphycus alvarezii has significant economic potential, particularly in the export market, due to its high carrageenan content. The study employed a quantitative approach using a descriptive and comparative research design. Data were collected through interviews, field observations, and structured questionnaires administered to seaweed farmers in both villages. The results showed that although Tablolong Village generated slightly higher gross revenue, Oenaek Village demonstrated greater production efficiency. These differences were influenced by several factors, including seed quality, cultivation techniques, market accessibility, and natural resource management. The findings provide valuable insights for policymakers and stakeholders in developing strategies to improve the economic performance and livelihoods of seaweed farmers in both villages. Keywords: Kappaphycus alvarezii; seaweed farming; economic analysis; production efficiency; Tablolong Village; Oenaek Village.

Abstract

Feed is a crucial factor in fish farming. Without appropriate feed, fish growth slows down, and survival rates can decline. High commercial feed costs often pose a challenge. Consequently, many fish farmers seek highly nutritious alternatives; bloodworms (Chironomus sp.) are a promising option due to their protein content, which supports fish growth. This study examined the effects of combining bloodworms with commercial feed on the growth and survival of Pangasius hypophthalmus (Siamese catfish). The experiment was conducted over 60 days at the Aquaculture Laboratory of Nusa Cendana University, Kupang, using a Completely Randomized Design (CRD). Four treatments were tested—control (100% pellets), Treatment A (85% pellets + 15% bloodworms), Treatment B (70% pellets + 30% bloodworms), and Treatment C (55% pellets + 45% bloodworms)—with three replicates for each. The results clearly indicated that the combination of commercial feed and bloodworms significantly influenced the growth of P. hypophthalmus (p<0.05). Treatment C (45% bloodworms) yielded the best growth performance, achieving an absolute weight gain of 2.73 g and a specific growth rate (SGR) of 1.27% per day. However, regarding survival, Treatment B performed best, achieving a rate of 86.66%. Water quality remained stable throughout the study, with temperatures ranging from 26–30°C and pH levels between 6.2–8.3—ranges ideal for P. hypophthalmus. The study concludes that incorporating bloodworms at a proportion of up to 45% alongside commercial feed can accelerate the growth of P. hypophthalmus without compromising survival rates.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kepadatan yang berbeda terhadap pertumbuhan dan kelulushidupan spat tiram mutiara (Pinctada maxima) di Balai Perikanan Budidaya Laut Lombok. Metodologi yang digunakan adalah metode Rancangan Acak Lengkap dengan 3 perlakuan dan 3 ulangan. Penelitian ini menggunakan Perlakuan A (Kepadatan spat tiram mutiara 10 ekor/poket) Perlakuan B (Kepadatan spat tiram mutiara 12 ekor/poket) Perlakuan C(Kepadatan spat tiram mutiara 14 ekor/poket). Hasil penelitian menunjukkan bahwa perbedaan kepadatan tidak berpengaruh signifikan terhadap pertumbuhan panjang mutlak, laju pertumbuhan spesifik harian. Namun, tingkat kelangsungan hidup mencapai 100% di seluruh kelompok perlakuan. Kualitas air yang terjaga dalam kisaran optimal, termasuk suhu, salinitas, pH, dan oksigen terlarut, mendukung pertumbuhan dan kelangsungan hidup spat tiram mutiara P. maxima
