Potatoes are an annual crop that are not environmentally friendly because the potatoes can accelerate the rate of erosion. Therefore, a cultivation method is needed in polybag. Planting in polybag need to know the weight of media and seeds number for growth and production of potatoes running optimally. The purpose of this study is examine potato cultivation in polybag to improving potato growth and production. Parameters observed were plant height, wet weight of potato, tuber number, tuber weight and tuber weight/polybag. The treatments were given are media weight (V 7 : 7kg and V 10 : 10 kg) planting potatoes in land as a control and number of seeds (2 grains: 3grains and 4grains). The treatment in this research do with factorial completely randomized design in 9 different treatment and 3 repeat. Data was analyzed by Analysis of Variance (ANOVA) at 95% confidence ...

We investigate the use of Sargassum sp. and Gracilaria verrucosa in enhancing the growth of Vigna radiata. The seaweeds were collected from Awur bay and shrimp pond in Jepara and Kendal, Central Java. The seaweeds was dried and soaked to reduce salinity, then dried again under the sun. The dried seaweeds were then finely powdered, and applied into sandy and clay soil at the proportion of soil conditioner: soil medium was 1:4. After 4 weeks composting, the mixed medium were used to plant the Vigna radiate seed. The growth of Vigna radiate was monitored by the height of the plant weekly. The collected data was analyzed using t test to compare before and after the use of seaweeds soil conditioner in certain type of soil. Results indicated that in sandy soil, Gracilaria was capable in increasing the growth of Vigna radiate by 23.86% (p=0.005). Whereas Sargassum sp increase the growth o...

These nitrogen compounds are the indication of eutrophication as nutrient enrichment in shrimp pond ecosystem is caused by the main component of feed, protein. Removal of ammonia, nitrite and nitrate from shrimp pond ecosystem is crucial as these compound are toxic to the shrimp. The aim of this research is to study the efficiency of using Gracilaria verrucosa, for nitrogen removal. The density of Gracilaria was used as treatments. The Gracilaria were arranged at density of 1kg/m2, 2kg/m3, and 3 kg/m3, and each density was put into 1m x 1m x 1.2m polyethylene enclosures, filled with 1 m3 brackish water. The performance of ammonia, nitrite, and nitrate were monitored during 8 weeks of experiments. Results indicated that the presence of Gracilaria significantly reduced ammonia, nitrite and nitrate in the shrimp pond. There was a highly significant correlation between density of Gracilaria with re...

The shrimp-Gracillaria polyculture system was hypothesized to reduce excess pollutant in the shrimp pond. Variation in Gracillaria density was used as treatments. Two important aspects are discussed in this paper, that are the effect on shrimp productivity and efficiency in carbon energy conversion into harvestable products. There were significant evidences that the shrimp-Gracllaria polyculture system increase the sizes, total biomass, survival and growth rate of shrimp. The density of Gracillaria was positively correlated with all of those parameters. The carbon energy conversion was also significantly affected by Gracillaria density. The carbon energy conversion into harvestable products was more efficient if Gracillaria density was increased.

Bogor Taro ( Colocasia esculenta (L.) Schott) is a perishable agricultural products at harvest time, so it takes a good handling to be able to maintain its quality as a functional food ingredient (instead of rice). This study aims to determine the long effect of storage on morphology changes, proximate and vitamin B 1 content of the tuber Bogor taro. The study design used Completely Randomized Design (CRD) for storage time of 5 days (K.I), 10 days (K.II) and 15 days (K.III) with three replications. The main parameters of the study are the morphological changes (weight loss, shrinkage diameter, tuber damage, the presence of buds) and the chemical changes (proximate and vitamin B 1 content). The parameters also play a role in the form of environmental storage conditions (temperature, humidity and light intensity).

Leachate rinses the dissolved materials, as well as organic materials from biological decomposition process. Decomposition process releases decomposition result quickly using available oxygen and creates anoxic environment. Leachate can cause water pollution, both of ground and surface water that needs to be handled properly. The aim of this study to evaluate the survival and performance of H.verticillata and E.crassipes as phytoremediator on leachate of Jatibarang landfill in Semarang. This research used leachate which is combined with fresh water. There were three repetition of it is treatment. The treatment are 100% leachate, 75% leachate dissolved with 25% fresh water, 50% leachate dissolved with 50% fresh water and 25% leachate dissolved with 75% fresh water. Phytoremediator plant in fresh water without leachate served as control. Results of the study showed that the presence of E. crassipes was effective in increasing pH and dissolved oxygen in leachate. Compared to H. verticillata, E. crassipes shows better survival growth rates and performance. To reach an optimum remediation result the leachate should be dissolved in 25% leachate and 75% of fresh water.

Kedelai melakukan adaptasi cekaman kekeringan dengan cara mengakumulasi prolin untuk melindungi sel dari kerusakan. Tujuan penelitian ini adalah untuk mengetahui pengaruh tingkat ketersediaan air terhadap pertumbuhan dan kandungan prolin pada tanaman kedelai varietas Wilis dan Grobogan. Penelitian ini dilaksanakan di Greenhouse Gombel Lama dan di Laboratorium Biologi Struktur dan Fungsi Tumbuhan Jurusan Biologi FSM Undip. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) pola faktorial, 2 faktor yaitu tingkat ketersediaan air dan varietas dengan 6 perlakuan dan 3 pengulangan. Analisis data menggunakan Analisis of Variance (Anova) dilanjutkan uji beda nyata Duncan Multiple Range Test (DMRT) pada taraf signifikasi 95%. Parameter yang diamati adalah kandungan Prolin dan pertumbuhan (tinggi tanaman, berat basah dan kering tajuk, berat basah dan kering akar). Hasil penelitian menunjukkan tingkat ketersediaan air berpengaruh terhadap kandungan prolin dan pertumbuhan. Ketersediaan air terendah menghasilkan kandungan prolin tertinggi, yaitu pada varietas Grobogan sebesar 2,15 µmol/gr dan Wilis 2,30 µmol/gr. Varietas tidak berpengaruh nyata terhadap kandungan prolin dan pertumbuhan tanaman kedelai, tetapi berpengaruh signifikan terhadap tinggi tanaman dan jumlah daun trifoliat. Varietas Grobogan lebih unggul terhadap cekaman kekeringan dibandingkan Wilis dilihat dari tinggi tanaman dan jumlah daun trifoliat.
