Embryo Incision as a New Technique for Double Seedling Production of Indonesian Elite Coconut Type âKopyorâ
One of the present major limitations of seedling production of kopyor type coconut using embryo culture is that only one seedling can be produced from a single embryo. Therefore, we report on the development of a new breakthrough technique for the production of double seedlings from a single embryo. The technique consists of four steps, viz. (i) germination; (ii) incision; (iii) splitting; and (iv) recovery. A histological study was carried out on the development of the halved embryo into a new shoot. The best recovery process was obtained when the incised embryo was split into two and recovered into Murashige and Skoog (MS) medium supplemented with 2 μM IBA and 15 μM kinetin. Following this protocol, an average of 56 shoots was successfully recovered from 30 zygotic embryos. The histological study also revealed that the meristem tissue of the halved embryo was able to produce a new meristem and primordial leaf. Most of the shoots then went on to produce normal seedlings and could be acclimatized successfully after having developed 2 or 3 leaves. This protocol is useful for routine seedling production of the kopyor-type coconut
Effectiveness of Herbal Diet Nigella sativa and Gracilaria verrucosa Against Non-specific Immunity of Tilapia (Oreochromis niloticus)
The addition of Nigella sativa and Gracilaria verrucosa to feed is used as a supplement to increase non-specific immunity in tilapia. The addition of herbal supplements is safe for consumption, easy to decompose, has no residue on the fish's body, and does not harm the environment. This study aims to find the effectiveness of the addition of the herbs Nigella sativa and Gracilaria verrucosa to increase non-specific immunity in tilapia. The study used an experimental method with a completely randomized design, applying 4 treatments and 1 control to tilapia. The dietary doses of Nigella sativa were T0 (control, without Nigella sativa), T1 (2.5), T2 (5), T3 (7.5), and T4 (10) (g kg-1 feed). While the dietary doses of Gracilaria verrucosa were T0 (control, without G. verrucosa), T1 (0.5), T2 (1), T3 (1.5), and T4 (2) (g kg-1 feed). The results showed that the percentage of hematocrite increased significantly with the Nigella sativa diet, while on the Gracilaria verrucosa diet, the percentage of hematocrit was not significant. Further, the Nigella sativa diet and the Gracilaria verrucosa diet can significantly increase the percentage of lymphocytes, but not significantly to the percentage of monocytes. In fish farming, the Nigella sativa and Gracilaria verrucosa diets have the potential to be used to increase non-specific immunity in tilapia, but it is more effective to use the Nigella sativa diet at a dose of 5 g kg-1 feed
RELIGIOUS MODERATION IN THE ACADEMIC ENVIRONMENT: A STUDY OF INTERNALISATION OF RELIGIOUS VALUES AND PATRIOTISM AT UNIVERSITAS LAMBUNG MANGKURAT
We are now facing a tsunami wave of social media development. Anyone and anywhere can access religious information. The impact of this correlates with the vital flow of globalization to all levels of society. The negative influence from the media development side gives a strong impetus for social insecurity. Our integrity as citizens will be at stake because of the appeal of social media. To maintain this, it is essential to strengthen and foster so as not to get out of the path of the nation's ideals. This research discusses how students establish relationships with God and each other in the frame of love for the homeland, surrounded by a plurality of religions, tribes, ethnicities, and cultures, to create an attitude of religious moderation. This type of research is included in field research with quantitative and qualitative approaches. Internalization of spiritual values and love for the homeland in students showed positive results. The results of respondent data show that the strong tendency of religious influence has a positive impact and correlates with love for the homeland. Based on the data, 60% strongly agree, and 28% agree with maintaining relationships with others regardless of anything. This reflects that students' religious understanding has shown an inclusive category, which means they can openly accept differences irrespective of religion, ethnicity, and culture, which is necessary in the Republic of Indonesia
Comparison of catching efficiency of two Indonesian traditional traps, Ayunan and Tamba
The catching efficiency of traditional traps: Ayunan and Tamba were tested in Sungai Batang River, South Kalimantan of Indonesia. Trials consisted of 320-trap hauls/type using 1-day submersion time of 24 hr. The baited traps sampling accounted for 82 specimens assigned to 5 species of 5 families. There was a large variability in number of catch between prawns and fish species collected (T=2.318, P<0.05). The prawns catch was represented by only the species Macrobrachium rossenbergii with total of 53 and 1,015 g weight. The prawns weight of Tamba was significantly higher than that of Ayunan (T=3.453, P<0.01).The fish catch composed of Mystus gulio 79%, Osteochilus hasselti 10%, Hypostomus plecostomus 7%, and Macrognathus aculeatus 3%, with total weight ranged from 35 to 560 g. A clear difference was found in catching efficiency. Comparative fishing trials showed that Tamba collected specimens were 1.8 times higher than Ayunan (T=2.223, P<0.05). Catch per unit effort for Tamba ranged from 58.13 to 80.00, and for Ayunan ranged from 5.31 to 7.19. The gear modifications and various treatments (e.g. bait odor, light) are necessary to be taken to increase their relative catching efficiency

Turmeric Flour Supplementation Through Feed-in Biofloc System Cultivation on the Growth of Nilem Fish (Osteochilus hasselti)
Nilem fish (Osteochilus hasselti) is favored by the community because of its chewy meat texture, good taste, and relatively cheap price, so it has the potential to be developed. However, the growth of nilem fish is slow therefore it needs to be given an immunostimulant to increase its growth. Biofloc is known as a cultivation system that can maintain water quality and provide sufficient floc for additional fish feed. This study aims to determine the effect of using turmeric flour in feed to increase the growth of nilem fish reared in the biofloc system. The study used a completely randomized design (CRD), with 3 treatments and 1 control each repeated 4 times. The treatments were supplementation of turmeric flour through feed at a dose of 1.125 g (B), 0.75 g (C), and 0.375 g (D) kg-1 feed and control (A) in cultivation with a biofloc system. The study lasted for 90 days with feeding 3%/kg of biomass weight given 2 times a day, in the morning and evening. Parameters observed in this study were weight (WG) and length growth (LG), daily growth rate (SGR), feed conversion ratio (FCR) and feed efficiency (EF). The data collection method was carried out by weighing and measuring the weight and length of the fish and the amount of feed consumed. The data obtained were collected and analyzed using SPSS 2.0.The results showed that supplementation of turmeric flour through feed reared in the biofloc system could increase weight and length growth, daily growth rate, feed conversion ratio, and feed efficiency. The optimal dose was obtained in the treatment of 1.125 g kg-1 feed (B), proving that supplementation of turmeric flour through feed has the potential to be applied to fish culture using the biofloc system

Non-Specific Immune Potentiating activity of Multivitamins in Catfish (Clarias sp.)
Fish farming is well developed because many people like to consume fish. The main problem in cultivation is an attack of a disease. Generally, the disease in fish is MAS (Motile Aeromonas Septicemia) which is caused by Aeromonas hydrophila. Prevention of diseases in fish can be done by increasing immunity through the addition of multivitamins in feed. This study aims to determine the ability of multivitamins against non-specific immune responses in African catfish (C. gariepinus) as well as to know the optimum dose. The study used an experimental method with a completely randomized design using 3 treatments, 1 control, and 4 individual replications. The treatment using a multivitamin through feed with a dose of T1 = 2 g kg-1, T2 = 2.5 g kg-1, T3 = 3 g kg-1 and T0 = control. The parameters observed were phagocytic activity, and differential leukocytes of monocytes and lymphocytes. Data were analyzed using Analysis of variance (ANOVA) at the 95% confidence level. If there is a real difference, then proceed with the Duncan Multiple Range test Test (DMRT) at a 95% confidence level. The results showed that the addition of multivitamins through feed on African catfish had a significant effect (p 0.05) on differential leucocytes of lymphocyte. The optimum dose for increasing non-specific immune responses in African catfish is T2 at a dose of 2.5 g kg-1 of feed. Based on research, the addition of multivitamins through the feed can potentially be used in fish farming to increase immunity
