Abstract

Reed is a grass that grows wild, widespread in the forests, fields, gardens and other open environments. The public generally considers that  it's weeds for agricultural land, but many industry companies utilize reeds for the purposes of drug raw materials, syrups and health drinks. Reed requires an open environment with high light intensity and a fertile soil for growth. Environmental conditions in Blora has a high light intensity and in Ungaran district has fertile soil, so that the differences in the environment can affect the quality of the reeds. The purpose of this study to know the environmental conditions, the number of stomata, morphometry of reeds. The design used was Completely Random Design by a single factor, namely the place of sampling in the area open fields in Blora and Ungaran. Sampling of each region performed 10 replication. Analysis of the data used is T test at significant level of 95% and 99%. Parameters observed that environmental conditions, the number of stomata, morphometry, the results showed that Blora has a light intensity and a higher temperature, humidity and precipitation lower than in the District Ungaran plant reeds in Blora has an average number of stomata less than in the area of plant Ungaran.The growth of reeds in Blora lower than the high reeds in Ungaran. Similarly, the thickness of the leaves of reeds in Blora thinner than the thick leaves of reeds in the area Ungaran. Reed rhizome in Blora slightly longer and a diameter longer than in Ungaran.   Keywords : Environmental condition, morphometry

Abstract

Production of sweet com, which is rich of carbohydrate, but less of protein and fat, still hasn’t fulfilled market needs. The increase of sweet com production may be carried out by improving the growth and production of this plant byproviding required hara element supply. This supply may be implemented by giving compost. The making of compost requires long time; it therefore should be added with stimulator EM4, namely liquid culture of microorganism like Lactobacillus, Actinomycetes and photosynthesis bacteria which may acceleratethe composing process. The problem formulation of this research is whether compost with EM4 stimulator influences the growth and producyion of sweet com and how many doze of compost with EM4 stimulator which may give the best result. The aim of the research is to evaluate the effect of compost with EM4stimulator against the growth and production of sweet com and also to evaluate the best doze of compost with EM4 stimulator which may gives the highest result. The research uses Complete Random Design with 4 treatments in which each treatment is repated 5 times. Those treatments are PO (control), P1 (compost 47,1 g/polybag), P2 (compost 94,2 g/polybag), P3 (compost 141,3 g/polybag). The obtained data was analyzed using ANOVA and BNT test when there is a significant difference.The result of the research indicates that compost with EM4 stimulator may increase the growth and production of sweet com and the doze of compost giving the highest result in the research is 141,3 g/polybag.

Abstract

Konsumsi oksigen dalam ekosistem perairan merupakan problem disebabkan karena respirasi oleh tanaman, hewan, bakteri dan organisme lain. Tumbuhan air efektif meningkatkan kadar oksigen dalam air melalui proses fotosintesis. Akan tetapi, tumbuhan air berperan sebagai pengguna oksigen terbesar melalui respirasi. Pengetahuan produksi dan konsumsi oksigen oleh Hydrilla verticillata Royle, Ceratophyllum demersum, Eichhornia crassipes Solms, Salvinia molesta All, dan Lemna minor sangat diperlukan. Penelitian ini bertujuan untuk mengetahui produksi dan konsumsi oksigen oleh tumbuhan air tersebut, serta mengetahui jenis yang paling potensial dalam mensuplai oksigen. Rancangan percobaan berupa Rancangan Acak Lengkap (RAL). Hasil penelitian menunjukkan rata-rata produksi oksigen paling tinggi adalah Ceratophyllum demersum yaitu sebesar 0,9 mg/L, sementara paling rendah adalah Salvinia molesta All dengan rata-rata produksi oksigennya negatif yaitu -0,58 mg/L artinya spesies tersebut tidak memproduksi oksigen ke dalam air tetapi justru mengkonsumsi oksigen di dalam air. Konsumsi oksigen paling banyak oleh Hydrilla verticillata Royle sebesar 1,43 mg/L, yang paling rendah oleh Ceratophyllum demersum sebesar 0,12 mg/L. Jenis tumbuhan air yang paling potensial menghasilkan oksigen adalah Ceratophyllum demersum karena memproduksi oksigen paling banyak dan mengkonsumsi oksigen paling sedikit
