The purpose of this research is to determine the concentration of young coconut water that is appropriate for the growth of orchid plantlets (Dendrobium sp.) In vitro. This study used an experimental method, descriptive data analysis to compare several different concentrations of coconut water. The design of this study uses a completely randomized design (CRD). The treatments consist of 0% coconut water concentration (as a control), 15%, 30% and 60%. Each concentration was carried out 5 replications and each repetition consisted of 5 Dendrobium sp plantlets in each culture bottle conducted for 40 HST, for observing the root length carried out for 50 HST. The highest number of shoots and leaves were produced at the same concentration, namely 150 ml / L coconut water treatment (15% concentration) with an average of 2.8 shoots and the average number of leaves 10.8 leaves. The average number of roots and the longest root length was produced at a concentration of 600 ml / L coconut water (60% concentration) with an average of 6 roots, and the longest root length was 0.5 cm.Keywords: Young coconut water, (Cocos nucifera L.), Dendrobium sp., in vitro, growth.ABSTRAKTujuan penelitian ini ialah menentukan konsentrasi air kelapa muda yang tepat untuk pertumbuhan planlet anggrek (Dendrobium sp.) secara in vitro. Penelitian ini menggunakan metode eksperimen, analisis data secara deskriptif untuk membandingan beberapa konsentrasi air kelapa yang berbeda. Rancangan penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Perlakukan terdiri dari konsentrasi air kelapa 0 % (sebagai kontrol), 15% , 30% dan 60%. Masing-masing konsentrasi dilakukan 5 kali ulangan dan setiap ulangan terdiri dari 5 planlet Dendrobium sp dalam setiap botol kultur yang dilakukan selama 40 HST, untuk pengamatan panjang akar dilakukan selama 50 HST. Jumlah tunas dan jumlah daun terbanyak dihasilkan pada konsentrasi yang sama, yaitu perlakuan air kelapa 150 ml/L (konsentrasi 15%)  dengan rata-rata jumlah tunas terbanyak 2,8 tunas dan rata-rata jumlah daun terbanyak 10,8 helai daun. Rata-rata jumlah akar terbanyak dan panjang akar terpanjang dihasilkan pada konsentrasi air kelapa 600 ml/L (Konsentrasi 60%) dengan rata-rata jumlah akar terbanyak sebanyak 6 akar, dan rata-rata panjang akar terpanjang 0,5 cm.Kata kunci : Air kelapa Muda (Cocos nucifera L.), Dendrobium sp., in vitro, pertumbuhan

This study aims to 1) to see the effect of natural phytohormones in onions and coconut water on the growth of sugarcane, 2) To see the effect of giving natural phytohormones to sugarcane plants which produce the best growth, 3) To see the results of research on the growth of sugarcane can be used biology learning resources. This type of research is an experimental study using a completely randomized design (CRD). This study consisted of 4 treatments, namely, the first treatment was giving sand and red soil, the second treatment was giving manure and 15% concentration of onion solution phytohormones, the third treatment was giving manure and phytohormones with 25% concentration of coconut water solution, the fourth treatment was Pembrian. Manure and phytohormone combined with 15% concentration of onion solution + phytohormone with 25% concentration of coconut water solution. The parameters observed in this study were height in units (cm), number of leaves (counting manually), stem diameter in units (cm). To determine the effect of phytohormone solutions on shallots and coconut water, data analysis was carried out using the one-way ANOVA test. and further tests to find out the most optimum treatment for the growth of sugarcane using the BNJ test. Based on the research, there was a significant effect of giving natural phytohormones on the growth of sugarcane, with the best treatment, namely the third treatment of giving manure and phytohormones of coconut water solution. The results of this research can be used as a source of learning biology in the form of videos with material on the growth and development of class XII. Kata kunci: larutan bawang merah (allium cepa L), air  kelapa (cocos nucifera L), fitohormon, tanamantebu.

ABSTRACTThis study aims to determine the proportion addition of soursop juice and analyze the chemical contents of isotonic drink from mature coconut water (Cocos nucifera L.) This research was conducted by adding 100 ml, 200 ml, and 300 ml of soursop juice to 1000 ml of coconut water. The test parameters were organoleptic tests using hedonic methods including flavor, taste, and turbidity. The best treatment was followed by chemical testing including sodium, potassium, acidity (pH), total acid and total sugar. The result of organoleptic test showed that 1000 ml of coconut water without soursop juice addition has a value of 2,73 (neutral), while the addition of 100 ml soursop juice has a value of 3,43 (neutral), the addition of 200 ml soursop juice has a value of 3,54 (like), and the addition of 300 ml soursoup juice has a value of 3,71 (like). In conclusion, the best result is the addition of 300 ml soursop that had a mineral content of sodium as much as 469,36 mg/kg, potassium as much as 2014,45 mg/kg, pH 4,65, total acid 0,54% and total sugar 6,33%. Keywords: Isotonic Drinks, Soursop Juice, Coconut Water

Introduction: Pain signals tissue damage that is capable of reducing thequality of life. Non-Steroidal Anti-inflammatory Drugs (NSAIDs) are known as effective analgesic drugs which have various side effects, therefore natural minerals are used as an alternative medicine for pain and inflammation, one of which is known to be coconut water. Hence this research was conducted to find out the differences of the analgesic effect between young coconut water (Cocos nucifera L.) with non-selective and COX-2 selective NSAID on mice induced with pain from acetic acid 0.6% 1 ml/100gBW of mice.Methods: True experimental, conducted at the Pharmacology Laboratory in Faculty of Medicine of Airlangga University involving the sample of 48 mice (6 groups). The recorded data was tested using the oneway ANOVA methodology before then continued with the posthoc test of LSD.Results: The addition of young coconut water (Cocos nucifera L.) with the dosage of 3 ml/100gBW, 4 ml/100gBW, and 4.5 ml/100gBW of mice doesn't give any significant analgesic effect even though the analgesic protection percentage increases accordingly to its dosage (12.32%, 18.72%, 26.88%), but non-selective and COX-2 selective NSAID give significant analgesic effect (p<0.05) on mice induced with pain from acetic acid 0.6% 1 ml/100gBW of mice.Conclusion: There are differences in the analgesic effect of young coconut water (C. nucifera L.) with non-selective and COX-2 selective NSAID on mice induced with pain from acetic acid 0.6% 1 ml/100gBW of mice.
