Abstract

بدأت هذه الدراسة من إرادة طلبة مدرسة دار النشاء ليستخدموا اللغة العربية يوميا. ولكن أنشطة تعليم اللغة العربية لم تجري جيدا لأن المدرس مازال يستخدم الطريقة خطابيا. حتى أنشطهم في المحادثة تكون غير فعالة وهذه تؤثر في مهارتهم الكلامية. وأهداف البحث معرفة وصف عملية تعليم الحوار باستخدام أسلوب التدريب ومعرفة أثرها في مهارتهم في تكلم اللغة العربية مع معرفة العوامل التثقيلية والتسهيلية فيها. ونتيجة هذا البحث أن تطبيق تعليم الحوار باستخدام أسلوب التدريب المتواصل معتبرة بالنظر إلى الأثر في عملية الدراسة والأثر في النتيجة. وتعليم الحوار في مدرسة دار النشاء الثانوية باندونج الغربية لاتخلو عن العوامل التثقيلية والتسهيلية. أما العوامل التسهيلية فيه فهي البيئة الجيدة، التسهيلات التعليمية المهيئة، ودفع الوالدين لأبنائهم. والعوامل التسهيلية فيه هي قلة الوسائل التسهيلية وكثرة الأوقات الدراسية.

Dwinanti et al, 2019. Siamese Fighting Fish (Betta splendens) Masculinization Using Coconut Water (Cocos nucifera) With Immersion Embrio Method. pp. 74-81. Most of male ornamental fish  have attractive color than female including Siamese fighting fish. Thus, male production is more preferable by farmer due to high demand on it. Sex reversal is a technology that reverses the direction of genital development from female to male (masculinization) or male to female (feminization). This research aims to determine the sex ratio of male fish resulting from immersion of Siamese fighting fish embryo with coconut water. This research was conducted at Basic Fisheries Laboratory Program Study of Aquaculture, Faculty of Agriculture, Sriwijaya University on February-March 2018. This research used randomized complete design (RCD) method with three treatments and three replications with 0% (control), 10% and 20%. The results showed concentration 10% resulted the best male percentage of siamese fighting fish i.e 91.06%. The highest hatching percentage was 90%, (at 0% concentration). The highest percentage of survival rate of Siamese fighting fish was 89% (concentration 20%). Embryonic immersion with coconut water can affect the percentage of hatching. The concentration at >10% didn’t give a good result of hatching percentage of siamese fighting fish. Water quality during maintenance were temperature 27.3-28oC, pH 5.9-6.3 and DO 4.2-5 mg.L-1.

Abstract

ABSTRACT The purpose of the study was to know the best salinity of eggs hatching period, the hatching percentage, the hatching rate, the percentage of normal larva and survival rate of baung fish larva (Hemibagrus nemurus Blkr.) until it 2 days age.   This research was conducted at Balai Benih Ikan of Gandus sub-district, Palembang, South Sumatra Province in February 2008. This research used the Complete Random Design with four different salinity treatments as like S0 (control), S1 (2 ppt), S2 (4 ppt), and S3 (6 ppt) by each three replications. Parameter observed the hatching period, the hatching percentage, the hatching rate, the percentage of normal larva, the survival rate of larva 2 days age, and  water quality. This result of the research showed that the salinity influenced evidently on the hatching capability of Baung Fish Eggs. The salinity 6 ppt had fastest time for the hatching period with of hatching time was 21.73 hours then hatch entirely after 29 hours. The best salinity for the hatching percentage (85,33%) and the hatching rate  (21.37 fish per hour) was 2 ppt. The control had the highest value (95.05%) for the percentage of normal larva. The salinity of 2 ppt had the highest value (82.59%) for the life of larva on age of 2 days. This measure of water quality is temperature (27.5 oC-28 oC), pH (7.00-7.12), DO (6.0-6.5 mg.L-1), and NH3 (0.05-0.09 mg.L-1).   Keywords: Hemibargus nemurus, salinity, egg hatching percentage

Abstract

ABSTRACT This research aims to determine the effect of natural  honey to male percentage of betta fish by masculinization. This researchwas conducted at FisheriesBasic Laboratory,  Faculty of Agriculture, Sriwijaya University on January– February 2018. This research  usedcompletely randomized design (CRD) with 5 treatments and 3 replications. The treatment in this research was4 day of betta fish larvae  that submersed in 5 ml/L  natural honey with different immersiontime.The treatmentconsisted of P0 (without natural honey), P1 (12 hours of immersion), P2 (16 hours of immersion), P3 (20 hours of immersion),and P4 (24 hours of immersion). The observed parameters were post-immersion survival percentage, percentage of male betta fish, post- rearing survival percentage and water quality. The result showed the percentage of male betta fish was 47,50 % (P0), 66,35 % (P1), 73,51% (P2), 75,37 (P3), and 85,14 % (P4). Water quality during maintenace were temperature 27,4-28,8 oC, pH 5,3-5,8, DO 3,43-3,59 mg/L and amonia 0’001-0,002 mg/L. Treatment of P4 (24 hours of immersion) indicatedthe best treatment with larval survival percentage andmale percentage were 90.00% and 85.14% respectirely. Keywords : Betta fish (Betta splendens), masculinization,natural honey
