Soybean is an important food crop after rice and maize. Soybean production in East Kalimantan based on the estimated 2014 rate is estimated at 1,263 tons of dry seeds. Compared to 2013 production there was a decrease of 139 tons (9.91%) (BPS, 2014). The low productivity is because soybean cultivation is still not optimal. One of the cultivation that can be done is by using Fish Waste and Solid POC. The purpose of this study was to determine the growth response of soybean (Glycine max l. Merril) by giving poc fish waste and solids. This research was conducted in Sidorejo Hamlet, Bilah Hilir District, Labuhan Batu Regency, North Sumatra Province. The research method used was factorial randomized block design (RBD) consisting of 2 factors, 9 combinations and 3 replications. The first factor was the provision of POC fish waste (P) consisting of 3 levels, namely: P0 = 0 ml / planting hole, P1 = 100 ml / planting hole, P2 = 200 ml / planting hole. The second factor is the provision of solid (S) consisting of 3 levels, namely: S0 = 0 ml / planting hole, S1: 100 ml / planting hole, S2: 200 ml / planting hole. Parameters observed were plant height, number of leaves, leaf width and stem diameter. Based on the results of research in the field, it shows that the provision of fish waste poc and solid has no significant effect on all observed parameters. Meanwhile, the interaction between poc and solid fish waste also had no significant effect on all observed parameters. Keywords: Soybean, POC Fish Waste, and Solid

This study aims to determine the factors that influence the level of income, to determine the level of profitability of vegetable farming and to find out whether the farming is feasible to run. This study uses the proportionated stratified random sampling method. Data were analyzed by multiple linear regression and R / C analysis. The results showed that simultaneously the factors that influence vegetable farming income had a significant effect on income at a trust level of 89%. Partially, fertilizer costs, pesticide costs, labor costs, education levels, and prices have a significant effect on income. The income contribution of vegetable farmers to the total income of farmer families is 80.02%. The value of R / C is 2.54, which means that vegetable farming is feasible financially.

The increase in market demand red spinach (Amaranthus Gangeticus) makes the prospects very promising less than optimal for the growth of red spinach (Amaranthus Gangeticus) because soil fertility is low so that the provision of organic material can improve soil fertility through the improvement of the physical, chemical, and biological soil so that it can support the growth of red spinach. This study aims to determine the dose of manure, the dosage of rice husk ash as well as the interaction of dosage that is optimal for the growth and yield of red spinach.this research was conducted experimental farm of the faculty of science and technology with a height of 28 meters above sea level Labuhanbatu district in March to October 2020. Research design using group factorial consisting of two factors. The first factor, namely the granting of cow manure (L) with three levels, namely : L0 = 0 ton/ha (control) L1 = 2 ton/ha, equivalent to 200 g/m2 (the recommended dose), L2 = 4 ton/ha, equivalent to 400 g/m2, L3 = 6 ton/ha, equivalent to 600 g/m2. The second factor, rice husk ash (A) consists of 4 levels, namely : A0 = 0 ton/ha (control), A1 = 1 ton/ha equivalent to 50 g/m2 (the recommended dose), A2 = 1.5 tons/ha, equivalent to 75 g/m2.The Parameters measured were plant height (cm), number of leaves (strands), Weight per Plant Sample (g). The results showed that the administration of cow manure 4 ton/ha, equivalent to 400 g/m2 can increase plant height, leaf number, and weight per Plant of amaranth red. The provision of 1.5 tons/ha, equivalent to 75 g/m2 can increase plant height, the number of leaves plant red spinach (Amaranthus Gangeticus).Keywords: Rice Husk Ash, Red Spinach, Cow Manure, Plant Growth

This study aims to see the differences in the speed of sprout growth with immersion systems and without water immersion. The results showed that there were differences percentage of seeds germinated between seeds that were given water immersion for 12 hours (85%) and were not given water immersion (65%). For the other parameter average days of sprouting, where the seeds that are given water immersion are more quickly induced by sprouts as much as 60% age 7 days after seedling, compared not given water immersion can only be induced by 40%. Likewise, the 17th day after the seedlings were induced by 85% for soaking seeds and 65% for seeds that were not soaking. Keywords: Rubber, Sprout, Water immersion

Chrysanthemum (Chrysanthemum indicum L.) is an ornamental plant that is included in an important contribution in the ornamental plant business. Related to chrysanthemum buds grown in vitro in culture tubes or bottles with a tightly closed to avoid bacterial and fungal contamination and to protect the humidity of the culture environment. However, this tight cap often affects the composition of the gas in a jar or bottle, which inhibits plant growth. The purpose of this study was to study the effect of photoautotrophic on the growth of chrysanthemum buds in the in vitro culture process and the differences in invitro and exvitro chrysanthemum stomata. This research was conducted in March 2016 to May 2016 in the Microtechnical Laboratory, IPB University. Research results obtained from research on the position given to research conducted on the number of roots, the number of books and the number of shoots. The influence of the environment of exvitro also significantly affects the number of stomata, stomata width and stomata density. Keywords :ex vitro, in vitro, photoautotrophic
