Abstract

This study aims to determine the effect of periphyton substrate density on the growth, survival, and production of tilapia saline (Oreochromis niloticus) biomass. This research was conducted for one month from January to February 2019 in the Soppeng Riaja District, Barru Regency, South Sulawesi Province. The containers used were 12 units of hapa-installed ponds (1x1m2). Periphyton substrate uses bamboo stems 8 cm in diameter and 1.2 m long. Then bamboo stems were stuck in each treatment except control. The design used was a completely randomized design (CRD) with 4 treatments and 3 replications. The results showed that the best weight growth was obtained in treatment D (72.2 grams / fish), C 42.5 grams / fish), B (28.3 grams / fish) and A (22.3 grams / fish), and growth the best length was obtained in treatments D (12.2cm), C (8.1cm), B (5.4cm) and A (4.4cm). Whereas the best survival rate was obtained in treatments D (96%), C (92%), B (88%) and A (84%), and the best saline tilapia biomass was obtained in treatment D (1.73 kg / m2), C (0.98 kg / m2), B (0.62 kg / m2) and A (0.47 kg / m2). Be concluded that different substrate densities affect the growth, survival, and biomass production of saline tilapia.

Abstract

Polyculture is a cultivation method used for the maintenance of many products in one field, polyculture has advantages over monoculture, especially the efficiency of spatial utilization, increased land carrying capacity and increased pond tilapia for pond farmers whose land is less productive. Vanammei shrimp (L. Van) is one of the fishery products that can make foreign exchange for the country and tilapia. The objectives to be achieved in this study were to see the optimal effect of polyculture of vanammei shrimp and tilapia by obtaining a rapid survival rate and growth for 2 months in the pond. The research was carried out for two months from May to June 2018. Traditionally, Tadang Palie village, Cempa sub-district, Pinrang Regency, South Sulawesi Province. The design used was completely randomized (CRD) with 4 treatments and 4 replications. Data were analyzed by ANOVA variance. The results showed that the growth rates of Vanammei shrimp and tilapia were highest in the treatment of Vanammei Shrimp (6.37 grams), B tilapia (8.28 grams) and the survival of vanammei shrimp and the best tilapia obtained in treatment B. (73 , 75%) vanammei shrimp and B tilapia (67.50%) and the best biomass was obtained in plot B (1499) while the best feed convection was obtained in treatment B. (1.22). Polyculture of vanammei shrimp and tilapia gives the best results.

Abstract

The study aimed how much the income of swallows nest in the district Maritengngae regency Sidenreng Rappang. The researcher used method of Sampling jenuh (sensus). This study was conducted in the district Maritengngae regency Sidenreng Rappang and using sampling 50 enterpeuners swallows nest. This study concist 3 group, little scale, average scale, and large scale. Study use analysis finansial Net Present Value, Net Benefit Cost Ratio, Gross Benefit Cost Ratio, Internal Rate of Return, and Payback Period. The result showed enterpeuner swallows nest little scale have income Rp20.000.00,00/year and the discount factor 6% NPV Rp48.454.578,00, Net B/C 2,29%, Gross B/C 1,60%, IRR 30,80% and PBP 2,96 the return of finansial during 2 years 9 month 6 days. The result showed enterpeuner swallows nest average scale have income Rp50.000.00,00/year and the discount factor 6% NPV Rp339.474.104,00, Net B/C 3%, Gross B/C 2,09%, IRR 29,93% and PBP 3,33 the return of finansial during 3 years 3 month 3 days. The result showed enterpeuner swallows nest large scale have income Rp120.000.00,00/year and the discount factor 6% NPV Rp940.852.808,00, Net B/C 3%, Gross B/C 2,09%, IRR 30,67% and PBP 3,26 the return of finansial during 3 years 2 month 6 days. Based on the study, the enterpeuner of swallows nest in the district Maritengngae regency Sidenreng Rappang feasible to developed because a provides economic benefits.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ekstrak daun kelor terhadap pertumbuhan, sintasan dan tingkat pewarnaan pada benih ikan cupang (Betta sp). Penelitian ini dilaksanakan selama sebulan. Dan pembuatan ekstrak daun kelor dilakukan di Green House Budidaya Perikanan Fakultas Pertanian, peternakan dan perikanan Universitas Muhammadiyah Parepare. Rancangan yang digunakan dalam penelitian ini adalah Rancangan acak lengkap (RAL) dengan empat perlakuan dan tiga kali ulangan. Hasil Penelitian diketahui panjang ikan cupang tertinggi dicapai pada perlakuan D yakni 5,36 cm, perlakuan C 5,16 cm, B 4,93 cm, D 4,66 cm. Berdasarkan nilai tingkat sintasan ikan cupang pada tiap perlakuan menunjukkan hasil 100%. Perubahan yang sudah terlihat terdapat pada perlakuan C dan perlakuan D dengan dosis 30 ml dan 45 ml sudah mengalami perubahan warna yang sangat jelas. Dan perubahan warna yang paling lambat terdapat pada perlakuan A yaitu 0 (kontrol) yaitu tanpa ekstrak daun kelor. Terdapat nilai selisih perubahan yang telah terjadi pada lampiran bahwa perlakuan D terlihat lebih besar perubahan peningkatan warnanya, sedangkan pengaruh penambahan ekstrak daun kelor dengan dosis 15 ml dan 30 ml terhadap peningkatan warna pada ikan Cupang Betta sp yaitu dengan jumlah 27 dan 29 dan peningkatan warna paling rendah yaitu dengan jumlah 6. Dan perubahan yang paling rendah didapatkan pada perlakuan tanpa penambahan ekstrak daun kelor dalam pakan yaitu pada perlakuan A(kontrol). Pada ikan cupang (Betta sp), warna merah yang paling dapat diperoleh dari ekstrak daun kelor pada pakan. This Study aims to determine the effect of adding Moringa leaf extract on growth, survival and staining level of betta fish (Betta sp). This research was carried out for a month. Moringa leaf extract was made at the Green House of Fisheries Cultivation, Faculty of Agriculture, Animal Husbandry, and fisheries, University of Muhammadiyah Parepare. The design used in this study was a completely randomized design (CRD) with four tretments and three replications. The results showed that the highest betta fish length was achieved in treatment D which was 5.36 cm, treatment C 5.16 cm, B 4.93 cm, D 4.66 cm. Based on the survival rate of betta fish in each treatment, the results showed 100%. Changes that have been seen in treatment C and treatment D with a dose of 30 ml and 45 ml have experienced a very clear color change. The slowest color change was found in treatment A, namely 0 (control), ie without Moringa leaf extract. There is a difference in the value of the changes that have occurred in the appendix that treatment D shows a greater change in color increase, while the effect of adding Moringa leaf extract at a dose of 15 ml and 30 ml on an increase in color in Betta fish (Betta sp) is 27 and 29 and an increase in the lowest color is the number of 6. The lowest change was obtained in the treatment without the addition of Moringa leaf extract in the diet in treatment A (control). In betta fish (Betta sp), the most red color can be obtained from Moringa leaf extract in feed.
