Abstract

Aphis gossypii  merupakan serangga hama kapas yang menyerang sejak tanaman muda sampai tanaman tua, akibat serangan A.  gossypii daun akan mengkerut dan rontok. Sehingga serangan A.  gossypii pada tanaman muda akan menghambat pertumbuhan tanaman/mati. Pengendalian yang diterapkan selama ini masih mengandalkan insektisida kimia, yang aplikasinya dengan penyemprotan maupun perlakuan benih sebelum di tanam (Seed treatmen) insektisida sistemik imidakloprit. Penggunaan insektisida kimia yang terus menerus dan berlebihan tentunya akan mengakibatkan resistensi, resurgensi dan pencemaran lingkungan. Untuk menunjang pertanian yang berkelanjutan perlu dicari alternatif pengendalian yang ramah lingkungan. Tembakau merupakan tanaman yang mengandung nikotin yang bersifat racun untuk serangga. Nikotin pada tembakau bisa di ekstrak dan digunakan sebagai insektisida nabati untuk serangga hama pengisap. Dalam makalah  ini akan di laporkan hasil uji efektifitas Ekstrak Nikotin Formula 1 terhadap mortalitas A.  gossypii. Penelitian dilakukan di Laboratorium Entomologi Balai Penelitian Tanaman Pemanis dan Serat, Malang mulai Juni sampai September 2011. Ekstrak Nikotin Formula 1 merupakan ekstrak daun tembakau dengan menggunakan ether, sedangkan A.  gossypii di ambil dari Kebun Percobaan Karangploso Malang dan di biakkan di laboratorium. Perlakuan konsentrasi Ekstrak Nikotin Formula 1 yang di uji yaitu 100%, 50%, 25%, 12,5%, 6,25%, 3,125% dan 0 sebagai kontrol. Perlakuan disusun dalam Rancangan Acak Lengkap dan diulang 3 kali. Hasil penelitian menunjukkan bahwa konsentrasi  25% menyebabkan mortalitas nimfa  A.  gossypii  93,33% pada 5 hari setelah aplikasi, sedangkan konsentrasi terendah 3,125% menyebabkan mortalitas sebesar 66,67%. Dengan demikian ekstrak nikotin formula 1 dapat digunakan sebagai insektisida nabati untuk mengendalikan  A.  gossypii , tetapi karena data hasil uji belum konsisten dan konsentrasi 25% masih terlalu tinggi sehingga masih perlu penyempurnaan ekstraksi agar diperoleh insektisida nabati yang efektif dan efisien.

Abstract

White oyster mushroom (Pleurotus ostreatus) harvest tend to reduced because  of  nutrients decreasing in the  growth media.  An effort  to increase its  production    is by adding nutrients  into  the growth media. This research aims to determine the effect of  nutrition  on growth  and production of  white oyster mushrooms. The nutrients used in this study is monosodium glutamate (MSG) and old  coconut  water.      The research method  used was  Complete Randomized Design  (CRD)  analysis  of variance  with  orthogonal  contrasts.  The treatments tested is the addition of nutrients after 3 times the harvest consists of four levels: control  (without  giving  nutrient solution), the provision of  nutrient solution Monosodium  glutamate  (MSG) 0.4%,  30%  old  coconut  water  and  nutrient combination of  MSG and old coconut water.  The results show that the addition of nutrients was not significantly different to the parameters of the total fresh weight, total  weight, mean  stalk  length,  average  diameter of  the bodies  and  biological efficiency of fruit.   However, it  significantly different  to the  parameters of maximum  hood width  average  and  buds  appearance time.   Based on  these observations we can conclude that feeding monosodium glutamate, old  coconut  water   and  combination of nutrients  monosodium  glutamate  and  old  coconut water  significantly  affect to maximum hood width  average  and  buds  appearance time.    Nutrition  as well as  without being given nutrients (control) of  body fresh  weight.  Nutrition old coconut water is better  than Monosodium  glutamate to maximum hood width average.  Monosodium glutamate or old coconut water nutrition  is better  than the  combination of nutrients monosodium  glutamate  and old  coconut  water  to the  long  shoots  appear.  Nutrition  increase wet weight up to 1.89%.

Abstract

Teak Forest Management in Indonesia began at period of Governance of Dutch Colonialism in1860. After independence of Indonesia in 1945, teak forest was managed by Department of Forestry and now was managed by Perum Perhutani. During that time  have been applied by various approach of management which relate to sustainable principles, but with existence of ecosystem change, degradation of indication resource and productivity that teak forest was not managed to sustainable principles. On the other side, commerce of world wood claim the quality of wood coming from managed forest on sustainability principles. This research aim to studying erosion at various of trees age and nutrient loss. Result of research showed that increasing of crop age was degrade the erosion. Soil lose affects of erosion could bring consequence to losing of soil nutrition. Mean losing of soil nutrition per hectare at various teak plants age is : ( 13,8 - 74,3) kg of N; ( 8,7 - 36,2) kg of P; ( 7,2 - 35,2) kg of K; ( 54,6 - 219,2) kg of Ca and ( 7,2 - 28,2) kg of Mg.

Abstract

Productivity improvement of physic nut can be done by the increase of female flowers numbers. Introducing of plant growth regulators (PGR )is one of many ways to stimulate flowering. The research was aimed to determine the dose of plant growth regulators NAA (Naphthalene Acetic Acid) which can increase the level of production and oil contents. This research was conducted at the Asembagus Experimental for 12 months. Five doses of 500, 1000, 1500, 2000, and 2500 ppm NAA were applied on two years old of J. curcas and arranged in a randomized block design with three replications. For comparison, treatment without PGR was added in treatments. The results showed that NAA application affected the growth plant height, canopy diameter and number of branches and production of fruit numbers, 100-seed weight and oil contents of jatropha. PGR application was able to increase the number of fruit and weight of 100-seed each for 26.64 and 2.07%, respectively, and to reduce the oil contents of 3.05% untreated PGR. Dose of 1000 ppm NAA was able to increase the fruit number and weight of 100-seed each for 35.09 and 2.99%, respectively and reduce the oil contents of 3.58%.

Abstract

The need for raw materials increase with increasing drug utilization of traditional medicine is increasing. Gendola is one type of potential medicinal plants, which have two varieties of the red gendola (Basella rubra L.) and white gendola (Basella alba L.). Saponin is one of the secondary metabolites from plants gendola. Appropriate planting medium is also a prerequisite of success, especially crop cultivation in containers. The purpose of this study was to investigate the effect and compare the composition of growing media on growth and saponin content in two varieties of plants gendola.The study was conducted in a plastic house agriculture Faculty of University orchard trial Trunojoyo Madura University Madura College of Agricultural Experiment Garden Trunojoyo Madura which lies at an altitude of ± 3 meters above sea level. The study began in November 2011  until Februari 2012. The method used was a factorial experiment based Randomized Design (CRD) with three replicates consisting of two treatment factors, the first factor is gendola different varieties of plants and the second factor is the combination of different growing.The result showed that the treatment plant varieties and combinations of place influende on plant length,  leaf number, leaf area, all part plant fresh weight and all part plant dry weight. Red gondolas varieties yield components of growth, biomass weightand content of saponins in the leaves is high. Growing composition 1 : 1 (½ sections of land: ½ cow manure) gave the highest growth component in plant fresh weight and all part plant dry weight. Treatment plant varieties and combination of composition of saponin in the leaves but a very real influence on each treatment factor. The highest saponin content of the red varieties while growing composition 2 : 1 (2/3 parts soil : 1/3 cow manure) and the planting composition 1 : 2 1/3 part of land : 2/3 cowmanure) gives the value highest. Control treatment is growing composition 1: 0 (1part soil : cow dung manure 0) gives the lowest value on the saponin content of leaves.

Abstract

The research was conducted  in February-July 2010 in the greenhouse University Farm, Cikabayan, Dramaga, Bogor. This study aims to determine the effect of irrigation frequency on growth and production of five strains of  lowland rice, to determine critical point of soil water potential  for  drought tolerant screening.  This study used a randomized block  design  which consists of two factors and   three replications  for each combination of treatments. The results of this study indicate that the frequency of irrigation effect on plant height  at 8 and 12 weeks after planting (WAP), the number of tillering at  8 and 12 WAP, leaf length, ratio length / width of leaves, flowering age, number of productive tillers, panicle length, panicle number, number of grain per panicle, the percentage amount of grain fill, the weight of dry grain harvest, canopy dry weight, dry weight of milled grain, and the percentage decrease in production.  Drought stress decreased production by 32.44%,  41.52% and 48.87%  respectively at irrigation frequency of  8, 12, and 16 days. At optimum conditions of water availability, rice strains that produce the highest production is strain 1, 2, and 5. In drought conditions, all strains tested decreased production. Critical point of  soil water potential were -35.9, -25.8 and 0.3 kPa respectively on the vegetative phase,   reproductive phase, and   ripening phase.
