Abstract

ABSTRACTInnovation of LED lamp are encouraged the research and development to obtain effective and eco-friendly fishing lamp. However, information about response, behaviour and retina adaptation of main target species to LED light are still limited. Meanwhile, this information is a key to determining intensity of effective LED light for fishing operation. The aims of this study are to determine response and retina adaptation of anchovy (Stolephorus sp.) to different LED colour. This research was performed to the anchovies with total length 4.80-6.10 cm, which were acclimated in the fish tank. Fish response was observed visually and recorded by video camera. Retina adaptation was analysed by using histology method through pigment and cone index at light zone respectively. The results showed the fish response to white LED 3.4 times was faster than blue LED. However times duration of anchovy at the lighting area was 1.8 times longer in the area of blue lighting. The anchovies were more responsive to white LED (p value= 0.0033) with the average number of fish was 45 individuals. White LED with illumination between 42-96 lux was the optimal illumination for fishing operation which can reach the highest cone index about 64-73%.Keywords: cone index, effectiveness, fishing, illuminationABSTRAKPenemuan lampu LED mendorong berkembangnya penelitian untuk menghasilkan fishing lamp yang lebih efektif dan ramah lingkungan. Namun informasi tentang respons, tingkah laku dan adaptasi retina mata ikan target tangkapan terhadap cahaya lampu LED masih terbatas. Pada dasarnya, informasi tersebut menjadi kunci dalam penentuan intensitas cahaya lampu LED yang efektif untuk penangkapan ikan. Penelitian ini bertujuan untuk menentukan respons dan adaptasi retina mata ikan teri (Stolephorus sp.) terhadap lampu LED dengan warna berbeda. Penelitian menggunakan ikan teri dengan panjang total antara 4,80-6,10 cm yang telah melalui proses aklimatisasi dalam bak penampungan. Pengamatan terhadap respons ikan teri dilakukan secara visual dan direkam dengan video kamera. Adaptasi retina mata ikan teri diamati berdasarkan hasil histologi dengan melihat nilai indeks pigmen dan indeks kon pada masing-masing zona pencahayaan. Hasil penelitian menunjukkan bahwa ikan teri 3,4 kali lebih cepat merespons lampu LED putih dibandingkan terhadap lampu LED biru. Namun ikan teri bertahan 1,8 kali lebih lama di area pencahayaan warna biru. Ikan teri lebih memberikan respons yang lebih baik pada LED putih (p value= 0,0033) dengan rata-rata jumlah ikan yang berkumpul di area pencahayaan sebanyak 45 ekor. Lampu LED warna putih dengan iluminasi cahaya antara 42-96 lux merupakan lampu paling ideal untuk penangkapan teri karena menghasilkan adaptasi sel kon paling tinggi dengan indeks kon antara 64-73%.Kata kunci:  indeks kon, efektivitas, penangkapan, iluminasi

Abstract

This research was aimed to know the effect of magnetic field strenght and duration of Immersion on Germination of ExpiredRice (Oryza sativa L.) Seed of Ciherang Variety. This research used a Randomized Complete Design with two factors. The first factor was magnetic field strenght (M) consisting of four levels, namely: M0 (0 mT), M1 (15 mT), M2 (20 mT) and M3 (25 mT). The second factor was duration immersion in magnetized water (T), which consists of three levels, namely: T1 (12 hours), T2 (24 hours) and T3 (36 hours). The combination treatment was repeated three times, so there was 36 experimental units. Observed variables were germination age (days), the maximum growth potential (%), growth rate (%/day), normal germination percentage (%) and abnormal germination percentage (%). The result showed that magnetic field strenght and magnetized water is not able to improved for all observed variables were germination age (days), maximum growth potential (%), growth rate (%/day), normal germination percentage (%) and abnormal germination percentage (%). There was an interaction between the magnetic field strenght and duration of immersion time. The interaction magnetic field strenght of 0 mT and 15 mT with 12 hours and 20 mT with 24 hours immersion. Improved the growth rate and normal germination percentage by 0,95 %/day and 13,33% consecutively.

Abstract

The study aims to determine the effect of the magnetic field strength and the duration of magnetized water on germination of 2 year old Tanggamus of expired soybean seeds. The study was carried out in a closed room with the temperature used was 16°C-20°C in Desember 2015 to January 2016. The study was compiled using a completely randomized factorial design with 2 factor. The first factor is the magnetic field strength which consist of 4 level M0 (the magnetic field strength of solenoid 0mT), M1 (the magnetic field strength of solenoid 1mT), M2 (the magnetic field strength of solenoid 2mT), M3 (the magnetic field strength of solenoid 3mT). The second factor is the duration of magnetized water which consists of 3 level T1 (the 18 hour duration of magnetized water), T2 (the 24 hour duration of magnetized water), T3 (the 36 hour duration of magnetized water). The treatment was repeated 3 times so that there are 36 units of observed variables experiment such as the germination age the potential of growth, the maximum speed of growth, the normal percentage of germination, the abnormal percentage of germination, the abnormal percentage of germination. The solenoid magnetic field treatment level 2 mT gave a very real influence on the parameters of the age of maximum growth potential, the growth rate, the percentage of normal seedliry of 6 month old and 2 year old expired soybean seeds. The treatments of soaking seeds with 24 hour duration of magnetized water produced the best developments on the 6 month old and 2 year old expired seeds even though there are differences in same of the best results in the observation parameter of both of the expired speeds. The best level treatment of 6 month old expired seed is the interaction of M2T2 level (the magnetic field strength 2mT and the duration of 24 hour magnetized water) which provided the best result to the parameter of maximum growth potential, percentage of normal germination, and percentage of abnormal germination. While the best level treatment of 2 year old expired seed is the interaction of M2T3 level (the magnetic field strength 2mT and the duration of 36 hour magnetized water) which provided the best result to the parameter of germination age, speed of growth and percentage normal germination.Key words : magnetized, solenoid, expiry, germination, soybean, seeds
