ABSTRAK The aim of the research was to determine the effect of different fish meal doses on the growth and survival rate of cachama fish (Colossoma macropomum) using the biofloc system in salin water. This research was conducted for 40 days from February 23 to April 3, 2019, which took place in the Technical Service Unit (UPT) Pool and Hatchery of the Faculty of Fisheries and Marine University of Riau. This research was using the experimental method by completely random design (RAL) one factor with three replications. The treatments were 2% feed dosage from fish biomass weight, 3% feed dose from fish biomass weight, 4% feed dose from fish biomass weight, and 5% feed dose from fish biomass weight. To minimize the error of each treatment level, repeated 3 times. The material used for biofloc technology is multi-cell probiotics, molasses and sea water which are diluted to 6 ppt. The results showed that the different feed doses to the maintenance of cachama fishwith biofloc systems in salin water affected the growth and survival of cachama fish. In addition, it also affects the daily growth rate, feeds efficiency and feeds conversion ratio. The optimal doses is found in treatment P4 (5% feed doses) resulting in an absolute growth of 8.64 g, growth of an average length of 8.51 cm, the specific growth rate of 4.9%, the survival rate was 100%, feed efficiency was 112.4 % and feed conversion ratio was 0.9.

Misalkan G adalah graf terhubung dengan V (G) adalah himpunan titik G. Misalkan W ⊆ V (G), dimana W = {w1, w2, · · · , wk}. Untuk sebarang titik v ∈ V (G), representasi titik v tehadap W dapat ditulis sebagair(v|W) = (d(vi, w1), d(vi, w2), · · · , d(vi, wk)), i = 1, 2, · · · , n, 1 ≤ k ≤ n.Jika representasi setiap titik di V (G) terhadap W berbeda, maka himpunan W disebut sebagai resolving set. Resolving set dengan kardinalitas minimum disebut resolving set minimum atau basis, sementara kardinalitasnya dinamakan dimensi metrik, dinotasikan dim(G). Misalkan terdapat dua graf siklus Cn, n ≥ 3 dengan himpunan titik Cn pertama V (Cn1) = {x1, x2, · · · , xn} dan himpunan titik Cn kedua V (Cn2) = {y1, y2, · · · , yn}. Tulisan ini mengkaji kembali makalah [1], yang membahas tentang penentuan dimensi metrik dari graf barbel B2n, dengan B2n ' 2Cn + {xnyn}, dimana diperoleh bahwa dim(B2n) = 2.Kata Kunci: Dimensi Metrik, Resolving set, Graf Barbel

This research was conducted to see how variations in population pressure on paddy fields, variations in the carrying capacity of paddy fields and to determine the optimum population size in Batipuh District. This type of research is descriptive quantitative. This research was conducted in Batipuh District, carried out from September to October 2020. The data analysis technique was obtained through the analytical tool used to calculate population pressure using Prof. formula. Otto Soemarwoto model II. The results showed that Batipuh District had experienced population pressure (TP <1). The highest value of population pressure in Batipuh District was in the village of Bungo Tanjung (106.8), while the lowest value was in the village of Sabu (39.9). The results of the analysis of the carrying capacity of the land show that there are 5 villages that are able to meet the food needs of their residents properly, namely Andaleh, Sabu, Batipuh Baruah, Pitalah, Bungo Tanjung. There are 2 nagari that are in class II classification, namely the Batipuh Ateh village and the Gunung Rajo village. Nagari with class III classification is only found in Tanjung Barulak village, which means that the village has not been able to provide adequate food. Nagari whose population has not exceeded the optimum limit consists of 7 nagari, namely; nagari Bungo Tanjung, Pitalah, Gunung Rajo, Batipuh Baruah, Batipuh Ateh, Sabu and Andaleh. Nagari whose population has passed the optimum limit is the village of Tanjung Barulak. Key Words: Population Pressure, Land Carrying Capacity, Optimum Population
