Abstract

Nepenthes mirabilis (Lour.) is a unique plant with a pitcher at the tip of the leaf. This species belongs to a rare category so needed to be preserved. One of the conservation efforts are the selection of the composition growing media for cultivation. This study aimed to found alternative planting media that can support the growth of Nepenthes other than sphagnum moss media. The research was conducted at the green house in Ngablak Village, Ngablak District, Magelang Regency from August to November 2020. This study used a Completely Randomised Design (CRD) with 4 treatments, sphagnum moss, roasted husk, roasted husk with cocopeat (3:1), sphagnum moss with cocopeat (3:1) given of 4 replications. Research parameter include, number of leaves, leaf length, leaf width, and plant height measured at 12 Weeks After Planting (WAP). Observation data were analysis by Analysist of Varians (ANOVA) and Duncan Multiple Range Test (DMRT) on a confidence level of 95%. The result showed that all treatment had a significant effect on the number of leaves, leaf length, leaf width, and plant height. The best planting medium was sphagnum moss with the time of appearance of the leaves (2,39 week), the highest number of leaves (11,25 sheet), and plant height (1,6 cm). the mixture media of roasted husk and cocopeat (3:1) produced growth that wsn’t different from sphagnum moss, so it was recommended to be a cheaper alternative media.

Abstract

The natural mangrove ecosystems along the Northern Coast of Central Java were very limited in extent, even had replanted almost twenty years ago. Naturally, the upper layer of sediment are the latest deposition (superposition). Environmental condition recently are recorded in the top sediment layer, and can be used to reconstruct past condition  (the present is the key to the past). The potential use of diatoms to reconstruct palaeoecology is well established. Diatoms are microscopic algae that form siliceous frustules which make them well preserved in sediment. Diatoms and their assemblages are very useful as integrated indicators of environmental changes because their distribution is closely linked to water quality parameters as well as their affinities to several physical habitats. This research was conducted in order to determine the changes of mangrove ecosystem in the Northern Coast of Central Java based on diatom stratigraphy. Sediment samples from mangrove sites were taken from Pekalongan, Brebes, Semarang, Demak and Rembang. Diatom analysis, consist of digestion, preparation, and identification. The diatom stratigraphy was performed by Software of  C2 1.5.1. Stratigraphycally, the mangrove ecosystems along the Northern Coast of Central Java were previously more influenced by freshwater rather than the marine sources which dominate today.

Abstract

Honey is the natural sweet substance produced by honey bees from the nectar of flowers. Honey composition is very complex, it contains at least 181-200 different substances, hence the enormous benefits of honey within pharmaceutical industry, food, beverage, and aesthetics. Although the demand for honey in Indonesia has been increasing, there is still no honey quality certification labeled on its product. This study used honey from several beekeeping region in Pati regency which has not been certified. The research aims to analyze honey quality based on water content, acidity, and total sugar. The sampling was purposive sampling method in the three different districts in Pati Regency, those were Gembong District, Gunungwungkal District, and Tlogowungu District, because in general this area is the main honey producer as there are many beekeepers and there is still no honey quality information labeled on it. This research used a Completely Randomized Design (CRD) with 3 treatments (locations) 4 replications from different beekeeper in each region. The water content and total sugar used a refractometer and acidity used titration. The research found that there is a significant difference between honey quality from different beekeeping region. The water content is ranged from 24-27,8%, acidity 59,2-68,3ml NaOH/kg, and total sugar 70,6-74,5 oBx. The highest honey quality is obtained from Gembong District with water content 24%, acidity 59,2ml NaOH/kg, and total sugar 74,5oBx.Keywords: Apis mellifera, water content, acidity, total sugar.

Abstract

Cotton (Gossypium hirsutum L.) is one of agricultural commodity which produces natural fiber as a raw material for the textile industry has a lot of constraints in its cultivation which not optimal, so the improvement of cultivation techniques by performing a balanced fertilizer can be done. Indonesian agricultural soil generally has low fertility rate and silica availability, so silica fertilization would be necessary. Silica causes leaves and stems of plant become upright so the photosynthesis will increased. Nanosilica that contains very small elements of silica which makes it easily absorbed by plants in order to increase growth and yield of cotton. This research aims to determine the effect of nanosilica fertilizer to the growth and production and also to know the effective amount of nanosilica concentration which will increase it of cotton Kanesia 8. The study design was using RAL with 5 different treatments of nanosilica fertilizer amount: 0 ml/L, 2.2 ml/L, 4.2 ml/L, 6.2 ml/L dan 8.2 ml/L with 5 repetitions. The data analysis was using ANOVA and if there is a significantly different then the analysis followed by further test of Duncan's Multiple Range Test (DMRT) at 95% of significance level. The results showed that nanosilica fertilizer with a concentration 2.2 ml/L increased the plant growth mainly at fresh weight of plant by 74.62% and dry weight of plant by 33.66% and it also increased the production of plant mainly in the percentage of fruit changed into cotton by 19.71% and dry weight of cotton by 0.98% than the control treatment.Keywords: nanosilica, growth, production, Gossypium hirsutum
