Abstract

This study aims to determine the effect of stocking density on the nutrient content of catfish that is cared with biofloc technology. Nutrients observed: 1) water content, 2) protein, 3) carbohydrates, 4) total fat, 5) saturated fatty acids / SFA, 6) monounsaturated fatty acids/ MUFA, 7) plural unsaturated fatty acids / PUFA , 8) omega-3, 9) omega-6, and 10) omega 9. Statistical tests on the 10 variables showed that stocking density did not have a significant effect on the 10 variables at a 5% confidence interval. Stocking density of treatment is 1000 heads/pond (T1), 2000 heads/pond (T2), 3000 heads/pond (T3), with a pond size of 2.0 m x height 1.0 m. Research results: 1. The average water content is 69.40–71.47% and the highest T3. 2. The protein content is 14.70-15.90%, the highest T2. 3. Carbohydrate content of 5.16-5.50%, the highest T2. 4. The average total fat content of 6.73-7.78%, the highest T1. 5. SFA content is around 43%, PUFA around 23%, and MUFA around 32%. 6. The highest omega-3 content is T3, then T1, and T2. Omega-6 and 9 sequence contents are T1, T2, and T3. It was concluded, the treatment of biofloc catfish stocking densities at a 5% confidence interval did not have a significant effect on the specified nutrient content. Penelitian ini bertujuan untuk menentukan pengaruh padat tebar terhadap kandungan zat gizi ikan lele yang dipelihara dengan teknologi bioflok. Zat gizi yang diamati: 1) kandungan air, 2) protein, 3) karbohidrat, 4) lemak total, 5) asam lemak jenuh/SFA, 6) asam lemak tak jenuh tunggal/MUFA, 7) asam lemak tak jenuh jamak/PUFA, 8) omega-3, 9) omega 6, dan 10) omega 9. Uji statistik terhadap ke-10 variabel menunjukkan padat tebar tidak memberikan pengaruh nyata terhadap ke-10 variabel pada selang kepercayaan 5%. Padat tebar perlakuan adalah 1000 ekor/kolam (T1), 2000 ekor/kolam (T2), 3000 ekor/kolam (T3), dengan ukuran kolam diameter 2,0 m x tinggi 1,0 m. Hasil penelitian: 1. Rata-rata kandungan air 69,40–71,47% dan T3 tertinggi. 2. Kandungan protein 14,70–15,90%, T2 tertinggi. 3. Kandungan karbohidrat 5,16–5,50%, T2 tertinggi. 4. Rata-rata kandungan lemak total 6,73–7,98%, T1 tertinggi. 5. Kandungan SFA sekitar 43%, PUFA sekitar 23%, dan MUFA sekitar 32%. 6. Kandungan omega-3 tertinggi T3, kemudian T1, dan T2. Omega-6 dan 9 urutan kandungannya T1, T2, dan T3. Disimpulkan, perlakuan padat tebar lele bioflok pada selang kepercayaan 5% tidak memberikan pengaruh yang nyata terhadap kandungan zat gizi yang ditentukan.

Abstract

All developers should consider continuity of water supply for the house dweller, as much rain water falling on the house yard will be lost as run-off water instead of filling the shallow ground water. Hence, there should be absorption wells to absorb the water falling from house roof. By so doing, it can increase ground water supply. However, there should be an exact dimension of the absorption well, as the amount of the falling water from house roof depends on the roof width. The dimension of the well for each house can be measured based on roof width, rain fall, and soil capability to absorb water or infiltration capability. For unrennovated house, well diameter are 80 to 120 cm and its total depth are 60 to 160 cm. While for rennovated house, well diameter are 90 to 140 cm and total depth are 120 to 190 cm

Abstract

This study is to reveal accuracy, recency, legibility,language, and physical appearance the main course material on Animal Food Substance(PANG 4221) by expert perception, lecturers, and students. The result of this study is expected to provide some useful recommendation for the revision of the course material of the Open University (UT). The data were obtained by capturing information from students of UT and non UT. The data obtained were analyzed by using descriptive qualitative methods. In addition, evaluation of the course material delevoped was conducted following the PAU-PPI format. The results the course material has high accuracy, legibility, language, materials, format, print, finishing and binding (score 3-4). However, despite high scores every aspect still needs to be revised because of some in consistencies. The recency, cover design, and content design have the lowest scores (2-3). These aspects must absolutely be revised. It can be concluded that the course material should be revised to include all findings from this study.

Abstract

The nutritional biofloc aquaponics system is a mutualism symbiosis between fish farming techniques and hydroponic plant cultivation. This system is an implementation of the spirit of urban farming and grow your own, which provides an answer to the limited land owned by urban communities as well as an effort to build food security for urban communities. This study aims to determine the effect of using biofloc catfish pond water and AB mix solution and the combination of the two for aquaponic cultivation of caisim, pakchoy, and kailan. Utilization of biofloc pond water and AB mix solution at a ratio of 1: 1 was able to provide the highest growth parameters in the form of plant height, number of leaves, and fresh weight for both caisim, pakchoy, and kailan plants. Biofloc catfish pond water can be used as a substitute for AB mix solution for aquaponic cultivation of caisim, pakchoy, and kailan. Keyword : biofloc catfish pond water, caisim, pakchoy, kailan
