Abstract

Liquid wastes originated from tofu industries (T), human excreta (HE) liquid waste and cow’s urine (CU) are rich in organic materials and they are potential as basic ingredient for liquid fertilizer.To understand the N, P and K content in the liquid fertilizer made from mixed waste and its effectiveness in improving the growth of phytoplankton, a study has been conductedfrom September to October 2015.There were 7 treatments applied, namely P1 (100% T); P2 (90 % T and 10% CU) ; P3(90% T and 10% EM4); P4 (90% T and 10% HE); P5 (80% T, 10% CU and 10% EM4); P6 (80% T, 10% CU and 10% HE) and P7 (70% T, 10% CU, 10% HE and 10% EM4). Results shown that P6 is the best, with 22.590 mg/L Ncontent and 153 mg/L Pcontent. The K content in all treatments was almost the same. Addition of the liquid fertilizer into phytoplankton media significantly increases the abundance of phytoplankton. The highest abundance was obtained in P6. Based on data obtained, it can be concluded that the liquid fertilizer made from mixed tofu liquid wastes, human excreta, cow’s urine and EM4 is effective for increasing the phytoplankton abundance.Keyword: Tofu liquid waste, human excreta liquid waste, cow’s urine, EM4, Liquid Fertilizer, phytoplankton

Abstract

Penelitian ini dilaksanakan pada bulan Maret 2015, yang berlokasi di Desa Sungai Selodang Kecamatan Sungai Mandau Kabupaten Siak Provinsi Riau. Penelitian bertujuan untuk: 1) Mendeskripsikan karakteristik nelayan di Desa Sungai Selodang tentang profesi nelayan; 2) Menganalisis persepsi nelayan di Desa Sungai Selodang tentang profesi nelayan; dan 3) Menganalisis hubungan karakteristik nelayan dengan persepsi nelayan tentang profesi nelayan. Metode yang digunakan dalam penelitian ini berupa metode survei dengan penentuan responden secara sensus.Berdasarkan karakteristik nelayan yang diperoleh, diketahui bahwa nelayan di Desa Sungai Selodang merupakan nelayan tradisional yang sangat berpengalaman dengan tingkat pendapatan sedang (mencukupi kebutuhan sehari-hari keluarga nelayan). Persepsi nelayan tentang profesi nelayan di Desa Sungai Selodang dilihat dari tiga kriteria yaitu, persepsi tentang wilayah perairan, penangkapan dan pendapatan berada pada kategori cukup baik dan secara keseluruhan persepsi nelayan tentang profesi nelayan berada pada kategori cukup baik, artinya profesi nelayan masih cukup disenangi atau diharapkan sebagai aktivitas nafkah nelayan. Hubungan antara persepsi nelayan dengan karakteristik nelayan berupa umur, jumlah tanggungan, pengalaman usaha, dan pendapatan memiliki hubungan negatif (berlawanan arah), sedangkan karakteristik nelayan berupa pendidikan memiliki hubungan positif (searah) dengan persepsi nelayan. Kemudian, semua variabel karakteristik nelayan (umur, pendidikan, jumlah tanggungan, pengalaman usaha, dan pendapatan) memiliki hubungan yang tidak signifikan (tidak nyata) dengan persepsi nelayan.Kata kunci: karakteristik, persepsi, profesi nelayan

The choice of location research done purposively or intentionally, with the consideration that there are areas of the river has become legally sand mining carried out by local people. The survey methode was used by case study in which by direct observation in the field, data collection was done by direct interviews with respondents based on the questionnaire that has been provided. Results of the research by the sand mining reduced the number of fishermen from ± 30 fishermen was reduced to 15 fishermen. The average income of the fishermen from the fishing in the river before and after at Rokan River sand mining activities before sand mining premises that the average ± Rp 2.733.000 and after sand mining decreased fishing revenue is ± Rp 1.446.000 this is due to lack of population polluted fish and the waters of the Rokan River. Sand mining activities have a positive impact and negative impact is felt by the local community to the social and environmental. Positive impact on the social is opening up jobs for the community, insufficient sand for the needs of the Development area as well as individuals and can develop creative power of the community, while the negative impact of his on the environment is the destruction of roads because frequently traveled by trucks of sand and the health impacts of society disrupted by of smoke and dust of the sand transport vehicle, the noise around river sand mining activities, pollution of waters in rivers such stem Rokan, and abrasion around the edge of the river..Keyword :Sand Mining,Income of Fishermen

Abstract

This research was held in June-November 2015 in Parasites and Fish Diseases Laboratory, Faculty of Fisheries and Marine Science, University of Riau Pekanbaru. This research aimed to determine survival rate of Pangasius hypopthalmus that are immersed in curcumin (Curcuma domestica V) and infected by Aeromonas hydrophila. This research used five treatment such as; Kn (negative control): were not immersed of curcumin and were not infected A. hydrophila, Kp (positive control): were not immersed of curcumin and infected by A. hydrophila), P1: immersed with curcumin 0,5g/L, P2 immersed with curcumin 0,7g/L and P3: immersed with curcumin 0,9 g/L. The fish were immersed with curcumin for two minutes each once a week and they were reared for 28 days.

Abstract

A research was conducted from January-February 2016 at the Fish Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Science, University of Riau Pekanbaru. The purpose of the research was to evaluate the duration of laser puncture exposure on gonad maturation of angle fish (Pterophyllum scallare). Completely randomized design was used to analyze the gonad maturation at the different duration of laser puncture exposure (0, 15, 20, and 25) seconds. The shooting was done twice a week for 4 weeks. The brood fish were reared in 54 L aquarium tank (60x30x35 cm) and fed on 38% protein pellet plus 57% protein tubifex worm.The results of research showed that there was an effect of laser puncture exposure duration, on gonad maturation of angle fish (Pterophyllum scallare). The best duration of laser puncture to stimulate gonad maturation was 20 second. At the duration the maturation was reached in 35 days with gonado somatic indeks 6,3 %, fecundity 908 eggs, and eggs diameter 1.5 mm. The temperature range from 26-27 oC, pH 5-6, and DO 5,7-6,8 ppm.Key words : laser puncture, gonad maturation, angle fish

Abstract

The research was conducted from 20 April 2015-14 July 2015. Thepurpose of this research was know the amount of water hyacinth in the diets ongrowth, feed afficiency and protein retention of river carp (Leptobarbus hoevenii).Five isonitrogenus (30% crude protein) experimental diets was formulated tocontain 0, 10, 20, 30 and 40% water hyacinth and 100, 90, 80, 70 and 60% soybenmeal (P0, P1, P2, P3 and P4, respectively. Completely randomized design (CRD)was used in this experiment. The results showed that a diet containing 40% waterhyacinth and 60% soyben meal (P4) support a good specific growth rate(1.0%/day) feed efficiency rate (22.23%) forage digestibility (54.95%) and proteinretention (24.54%). Survival rate of fish was high (98%). In this concluded that upto 60% soyben meal can be substituted with water hyacinth in the diets for rivercarp.Key word: Diet, growth, Leptobarbus hoevenii, substitution, water hyacinth
