Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung biji buah nangka (Artocarpus heterophyllus) terhadap pertumbuhan dan sintasan ikan nila (Oreochromis niloticus). Penelitian ini menggunakan metode percobaan (eksperimen). Rancangan yang digunakan dalam penelitian adalah Rancangan Acak Lengkap (RAL) menggunakan analisis sidik ragam (ANOVA) dengan 4 perlakuan dan 3 kali ulangan. Hewan uji yang digunakan adalah benih ikan nila dengan ukuran panjang ± 5.2 cm dan berat ± 2.23 gram sebanyak 120 ekor. Perlakuan yang digunakan adalah perbedaan dosis pemberian pakan berbahan dasar tepung biji buah nangka, yaitu perlakuan A (5%), B (7%), C (9%) dan D (11%). Pelaksanaan penelitian dilakukan selama 4 minggu. Hasil penelitian menunjukkan bahwa pemberian pakan berbahan dasar tepung biji nangka dan tepung ikan dengan dosis berbeda tidak berpengaruh terhadap pertumbuhan benih ikan nila.Sintasan terbaik dihasilkan pada pemberian pakan dengan dosis 5 %.

Ponelo Islands is an important area to be developed with the economic potential of fisheries and marine resources. This research was conducted in May-September 2019 aimed to find out Ecological Parameters as the Basis of Bivalvia Management in Seagrass Ecosystems. The sampling method is done by using the method used in determining the observation point is the linear quadratic transect method with sampling bivalves determined intentionally with a systematic perpendicular direction using a transect measuring 1x1 m. All bivalves contained in transects / quadrants are counted and identified. The sampling locations were divided into 4 (four) stations, namely Station I (Otiola Village), Station II (Ponelo Village), Station III (Malambe Village), and Station IV (Tihengo Village). Observations at the study site found several types of seagrass ecosystems including Enhalus acoroides, Halodule pinifolia, Thalassia hemprichii, and Cymodocea raotundata. Furthermore, 8 (eight) types of bivalves were found which were divided into 4 (four) stations in Ponelo Islands, namely Isognomon isognomum, Pinna muricata, Semele crenulata, Tellina virgata, Trachycardium subrugosum, Spondylus tenellus, Tapes sulcarius, Anadara pilula. The highest abundance index value is Tellina virgata found in Otiola Village with a value of 77.78%. The dominance index value for the highest is in Ponelo Village with a value of 0.88 in the high category. diversity index (D') with a value of 0.63 found in the medium category Malambe village.

Lake Limboto is the largest lake in Gorontalo province including 15 Lake baggage that will be restored by the government. Pollution occurring in Lake waters is an important issue that needs to get the attention of various parties. Research aims to determine the status of environmental quality of the area, reviewing heavy metals (Hg, Pb, Cd) in water fishes and sediments, knowing the correlation between the fish and sediment. Sampling method is performed on 12 sampling points specified in purpose sampling. The method of analysis is used with government regulation No. 82 year 2001 on water quality and pollution control, measurement of heavy metal concentration SNI 06-6992.2.2004 by using Atomic Absorption Spekphotometer (AAS). The mercury content (Hg) of water in the 0.0019-0.1216 ppm range has exceeded the limits based on quality standards, lead (Pb) ranges between 0.008-0.0463 ppm while cadmium levels (Cd) range 0.007-0.0085 mg/L in general the value difference between stations is not Much. The content of mercury heavy metals in fish 0.0079-0.0631 as well as the heavy metal content of Pb is 0054 mg/L while the cadmium (Cd) content 0.017-0.058 mg/L. The concentration of heavy metals Hg 5.81-5.72 mg/L, the average Pb heavy metal 0.5571 mg/L whereas the heavy metal cadmium 0.6190 mg/L. The correlation of heavy metal mercury with water is an index of 1.00 showing strong relationships while the correlation of the heavy metals Pb 0233 has a weak and negative relationship and the Cd heavy metal is the 0.019 that shows a low correlate.

The Limboto Lake is the largest lake in Gorontalo Province. These natural resources have biodiversity of fishery which become economic source of coastal lake community. Besides, the economic activity of aquaculture fishery also grows rapidly in Limboto lake. The Limboto Lake is the largest lake in Gorontalo Province. These natural resources have biodiversity of fishery which become economic source of coastal lake community. Besides, the economic activity of aquaculture fishery also grows rapidly in Limboto lake ,The Limboto Lake has a strategic role for the province of Gorontalo. The Limboto lake degradation shows a more destructive of the area and the depth is reduced. This research study the product of law as a environmental politic instrument of the government and analyzes it in a political ecological perspective. The research design used descriptive quantitative and qualitative by using methodological approach of political ecology. The results show that regulation related to general management of the lake and Lake Limboto is particularly weak in the context of cohesiveness, harmonization, and problem focus. Danau Limboto merupakan danau terbesar di Provinsi Gorontalo. Sumberdaya alam ini memiliki kakayaan hayati perikanan yang menjadi sumber ekonomi masyarakat pesisir danau. Disamping itu aktivitas ekonomi perikanan budidaya juga tumbuh pesat di danau Limboto. Danau Limboto merupakan danau terbesar di Provinsi Gorontalo. Sumberdaya alam ini memiliki kakayaan hayati perikanan yang menjadi sumber ekonomi masyarakat pesisir danau. Disamping itu aktivitas ekonomi perikanan budidaya juga tumbuh pesat di danau Limnboto. Danau Limboto memiliki peran strategis bagi provinsi Gorontalo. Degrdasi danau Limboto menunjukkan gambaran semakin destruktif yaitu luasan dan kedalamannya berkurang. Penelitian ini bertujuan untuk mengkaji produks hukum sebagai instrumen politik lingkungan pemerintah dan menganalisis dalam perspektif ekologi politik. Desain penelitian yang digunakan deskriptif kuantitatif dan kualitatif dengan menggunakan pendekatan metodelogis ekologi politik. Hasil menunjukkan bahwa regulasi terkait pengelolaan dananu secara umum dan danau Limboto secara khusus masih lemah dalam konteks keterpaduan, harmonisasi, dan fokus masalah.

This study aims to determine the population density of Spirulina sp cultured on Walne media with different salinities (20‰, 25‰, 30‰, 35‰) on a laboratory scale. The method used is an experimental method using a completely randomized design. The results showed that different salinity had an effect on the cell density level of Spirulina sp for 10 days. The maximum total biomass density of Spirulina sp was 6071889.597 cells/ml at 30‰ salinity treatment, and the lowest biomass growth was 4187919.321 cells/ml at 20‰ salinity. Statistical analysis (ANOVA) showed that the difference in salinity to the density of Spirulina sp cells had a significant effect where the value (Fcount > Ftable) was at the 5% level.

Tilapia is an important commodity for Indonesian fisheries. Therefore, tilapia cultivation continues to grow. The goal is to meet market needs and increase production more optimally. One of them is through feed innovation to increase growth and maximum survival. This study aimed to explore the effect of giving vitamin premix with different doses on the growth and survival of saline tilapia (Oreochromis niloticus) fry. The method used is an experiment with a completely randomized design (CRD) which consists of 4 treatments with three replications. Treatment A (without added vitamins), B (vitamin premix 3%), C (vitamin premix 4%), D (vitamin premix 5%). The results showed that treatment D had a significant effect on increasing the weight and length of saline tilapia with an average weight value of 3.21 and an average length value of 2.67, followed by treatment C weight with a value of 2.50 and a length of 2, 05, treatment B was heavy with a value of 2.49, and length of 1.86 and treatment A was heavy with a value of 1.60, and length of 1.23. The highest survival was in treatment D with a value of 100%, treatment C with a value of 93.3%, treatment B with 86.7%, and treatment A with 80.0%. Vitamin premix dose D gave the best effect, so it has the potential to be applied in saline tilapia cultivation.
