Abstract

Jali (Coix lacryma-jobi L.; Poaceae) is a potential cereal for food diversification especially as carbohydrate source. The aim of this current research was to study the productivity of jali cultivated under various doses of fertilizer. Jali were planted on polybag (30x40 cm) with mix-ture of soil:compost=2:1 as planting media. Fertilizer treatments were A) 0-0-0; B) 2-1-1; C) 2,5-1,5-1,5; D) 3-2-2-; E) 3,5-2,5-2,5 and F) 4-3-3 gram urea:SP36:KCl (gr/polybag). The experiment used randomized block design with 9 replications. Result indicated that on 13 WAP (Week After Planting) the highest plant height achieved on 2,5-1,5-1,5 treatment (198,44 cm), leaf number on 4-3-3 treatment (65,44), tiller number on 4-3-3- treatment (4,22), and branch number on 2,5-1,5-1,5 treatment (5,89). These measurements were significantly different from control but not with the other fertilization treatments. On harvesting time of 6 MAP ( Months After Planting) the highest number of seed/plant was from treatment 4-3-3 (792,6) followed by treatment 2-1-1 treatment (672,5). The result of this study suggested that 2-1-1 gram Urea:SP36:KCl (gr/polybag) treatment was the best in increasing hanjeli productivity.

Abstract

Limited water supply on dry season at dry terrain,cause plantation index and plant productivity low. Mean while yearly water volume are potentially enough for twice plant even more if they manage well. Because of that reason using and developing water resource by rainfall and run off harvesting technology, increasing productivity and maintain dry terrain farm operations system at watershed system are approximation strategy needed to put into practice. That strategy can put into practice through hydrologist characteristic modification at river flow area with escalating capacity and capability watershed distribution to minimalist inundation risk and dried out at dry season. Research result at sub watershed Bunder, Wonosari, DIY by way of building two level dam at river bed (hydrology network) can producing 11.6% (channel reservoir 1) and 18.4% (channel reservoir 2) surface flow from existing river-bed and this result can supply water irrigation at least 3 times in planting season rice-secondary crop- secondary crop). If cropping pattern change to rice-rice-secondary crop then run off harvest need to increase become 100% at upper subwatershed (channel reservoir 1) and 19% at lower subwatershed, with condition at MK 1.irrigation area that can be plant with rice only 0.19 ha and the rest of it can be plant with peanut. Rice productivity at rice field are 2.4 ton/ha.

Abstract

Kedawung is a member of the plant genus of Parkia (Mimosaceae). It has important value as traditional medicine and currently has been included in the Indonesian list of endangered medicinal plant species. There are two closely related species to Kedawung in Java: P. intermedia and P. speciosa. Parkia intermedia has long been assumed to be a hybrid between P. speciosa and P. timoriana. The species has leaflets linear-oblong and obtuse apex in mature foliage resemble P. speciosa, but has more numerous leaflets, linear-falcate, and acute apex in its juvenile leaflets similar to P. timoriana. Thus Hopkins (1992) included Petir as uncertain species. The aim of this study was to assess its current existing populations, to clarify the taxonomic status and to evaluate the similarity between kedawung and its related species. Exploration, morphology and leaf anatomical studies, as well as phenetic analysis have been conducted. The results indicated that morphology and leaf anatomical characters can be used to distinguish P. timoriana, P. intermedia and P. speciosa as different species, and P. intermedia was more closely related to P. speciosa than to P. timoriana.

Abstract

The successfull cultivation of useful plant largely depends on the quality of seeds, especially viability and germination vigor. Seed of Picrasma javanica Blume has potential use in the development of templates for new drugs, e. g. to treat malaria.For most species there is still little or no information about the suitable temperature regime for germination and seedling depelopment,therefore,it is interesting to study germination and seedling vigor of Picrasma javanica. The mature green were picked and cleaned before using for experiments.Germination was carried out in 24 compartments of a thermogradientbar apparatus.The temperature gradient extends from 4.8 to 41.6°C with 1.6°C steps from the first to the 24 th compartment. Twenty seeds were germinated in each compartment. Seeds were sown on 2 layers of filter-paper strips.Everyday for 77 days during germination the germinating seeds were recorded.For hilling experiments those seeds from compartment number 3 to number 13 of thermogradientbar apparatus were than removed to incubator 32°C for 28 days. On the seedling vigor, all germinating seed from incubator were removed for replanting in growth room with sand medium. The seedling establishment capacity in the different thermal regions can thus be identified. The results showed that seeds attained 50% germination after 43 days when placed at the gradientbar 22.4°C to 41.6°C with optimum temperature 36.8°C. A 28 days temperatuture pretreatment ranging gradually from 4.8°C up to 20.8°C has promoted germination significantly. Mechanism of pretreatment on low and high temperature was discussed.

Abstract

To increase domestic and international demand of Kencur (Kaempferia galanga L.) makes this plant potentially develop.Is traditionally used to keep the body warm, as analgetic and expectorant. In the attemp of providing adequately and qualitatively uniformed supply, in vitro experiment has been conducted at BB-Biogen (Indonesian Center for Agricultural Biotechnology and Genetik Resources Research and Development).The selected rhizomes was used as explant. The experiment was orthogonally arranged consisting of MS vitamin and B5, and BA ( 0, 3 and 5 mg/1) and thidiazuron 0,1 mg/1. This experiment comprised three activities, they were shoot initiation, shoot multiplication and acclimatization. The result showed that MS + BA 3 mg/1 + thidiazuron 0,2 mg/1 could induce shoot formation. From the applied media, it was shown that the addition of MS vitamin at the MS basic media and BA 3 and 5 mg/1 added with thidiazuron could result the most optimum shoot, leaves and roots and was not significantly different from the addition of B5 vitamin at basic media of MS + BA 3 and 5 mg/1, 6.9 shoot was averagely produced in this media. The shoot could generate such an adequate number of root that it could be directly acclimatized. The acclimatized plantlet in the green house uses the mixture of soil and manure with the ratio of 1:1 can optimally grow.

Abstract

Spodoptera litura (F.) (Lepidoptera: Noctuidae) is one of the agricultural pests that attacking almost all kinds of herbaceous plants, especiallyvegetables. Insect control using entomopathogenic bacteria is an alternative strategy that is effective and has a lower environmental impact than the use of synthetic insecticides. The purpose of this research was to explore entomopathogenic bacteria that have insecticidal activity against S. litura larvae at various stages of instars. The result showed that 25% of total number of isolated bacteria have potency as entomopathogenic bacteria. Isolate Staphylococcus sciuri strain BLSP-3 and isolate Serratia sp. strain BLSP-4 showed the highest larvicidal activity against the first and second instar larvae of S. litura 83% and 86%, respectively. The activity against on the third instar larvae however was only by 40%. However, the mortality caused by both isolates was lower than that of Bacillus thuringiensis (more than 90% mortality to the first and second instars and 80 % of the third instar larvae). It is suggested that both of isolates are potential to be developed further as a biocontrol agent to control S. litura population.

Abstract

Dalam peradaban timur, cendana telah digunakan secara tradisional semenjak 4000 tahun yang Ialu. Minyak atsiri yang diperoleh dari kayu cendana digunakan dalam upacara keagamaan dan sebagai obat-obatan. Dalam kebudayaan barat, cendana hanya digunakan sebagai bahan parfum kelas utama. Bam setelah tahun 1920-an, sejalan dengan perkembangan aromaterapi, bangsa barat mulai memanfaatkan cendana sebagai bahan obat-obatan. Minyak atsiri adalah substansi kimia yang membuat cendana menjadi berharga, baik secara ekonomi, bahan obat dan bahan parfum. Setiap bagian tumbuhan cendana memiliki kandungan minyak atsiri yang bervariasi. Bagian akar memiliki kandungan minyak tertinggi, yaitu 10 %, kemudian diikuti oleh bagian teras batang (4-8 %) dan ranting (2-4 %). Delapan puluh sampai 90% dari minyak cendana terdiri dari senyawa santalol dengan isomer a-santalol dan p-santalol sebagai komponen utama. Dalam perdagangan intemasional, minyak cendana kelas satu haruslah mengandung santalol minimal 90% dari kandungan total minyaknya. Dalam aromaterapi minyak cendana dikenal sebagai salah satu bahan alami yang berkhasiat sebagai sedatif, relaksasi dan mengatasi kasus insomnia serta serangan asma. Laporan terakhir juga menyebutkan bahwa minyak cendana bersifat menghalangi efek karsinogenik dari zat kimia. Alpha-santalol sebagai komponen utama minyak cendana dapat mengurangi kasus papiloma (tumor kulit) sebesar 32 %.

Abstract

Fertilization with organic and inorganic fertilizers increase the availability of nutrients in the soil and improve soil physical and chemical properties, The nutrient must fulfill crop requirement regarding to its effect to seed quality. The object of experiment was to study the effect of a combination organic fertilizer and inorganic fertilizer to resilience of soybean {Glycine max (L.) Merr.} seed var. Anjasmoro. Storage of seeds, were conducted in the Post Harvest Laboratory of Balai Penelitian Pertanian Lahan Rawa-Balittra (Indonesian Swampland Agriculture Institute), Banjarbaru from October 2009 until April 2010. The experiment was designed in completely randomized with 4 replications. Seed water content, seed germination, vigor index, electrical conductivity and seedling development were observed. The results showed that during storage, water content of seed increased 3-4% and limit the water content of seeds was still able to be maintained at <13%. Organic matter and NPK fertilizer declined vigor and germination of seed. Vigor is still above 70% and germination as high as >77%; As lower as seed germination generate as higher as electrical conductivity and lower the seedling dry weight.
