Abstract

Hubungan sifat-sifat agronomis terhadap indeks tanaman dan kadar nikotin telah dicari dengan analisis lintas. Tujuan dari analisis adalah untuk mengetahui pcubah bebas yang sangat mempengaruhi peubah yang tidak bebas, indeks mutu dan kadar nikotin daun, sehingga dapat mengurangi banyaknya pengamatan yang dilakukan. Data pengamatan agronomis yang meliputi : jumlah daun/pohon, luas daun ke-7, luas daun ke-15, bobot rajangan kering/ha, indeks mutu dan indeks tanaman diperoleh dari percobaan pemupukan tiga galur harapan tembakau Virginia di kebun percobaan Pekuwon Bojonegoro dari bulan Mei sampai dengan Oktober 2002. Hasil analisis lintas antara indeks tanaman dengan peubah bebas di atas menunjukkan bahwa indeks tanaman sangat ditentukan oleh bobot rajangan kering dengan koefisien lintas pm-1.03367 dan koefisien dcterminasi parsial 102%. Hubungan lintas bcrantai melalui pcubah rajangan kering dan indeks mutu menunjukkan bahwa luas daun kc-7 sangat mempengaruhi rajangan kering dengan koefisien lintas (p„i)- 0.85257 dan rajangan kering sangat mempengaruhi indeks tanaman dengan koefisien lintas (p,x,)= 0.95639, indeks mutu pengaruhnya terhadap indeks lanaman sangat kecil dengan koefisien lintas p,M = 0.12316. Analisis lintas antara kadar nikotin daun dengan ke lima peubah tidak baik (unfit) dengan koefisien sisa p„,= 0.6827 melebihi koefisien lintas yang lainnya. Dengan pentingnya peubah rajangan kering ini maka penjualan daun segar yang dilakukan oleh petani tidak dianjurkan.Kata kunci: Nicotiana tabacum, tembakau Virginia, analisis lintas, jumlah daun, luas daun, indeks tanaman, indeks mutu, kadar nikotin, bobot rajangan ABSTRACT Path analysis of agronomical characteristics on crops index and nicotine content of Virginia tobacco Bojonegoro The relationship between agronomical characteristics and crops index or leaf nicotine content has been studied by using path analysis. The purpose of this analysis was to determine the independent variables which most affected the dependent ones as crops index and leaf nicotine contain, so that it could reduce the number of independent variables. The agronomical characteristics consist of leaf number/plant, seventh and fiteenth leaf area, dried slice leaf/ha, grade index and crop index obtained from fetilizer experiment on three Virginia tobacco lines at Pekuwon Experimental Garden Bojonegoro, from May to October 2002. The results of this path analysis showed that crop index was strongly affected by dried slice leaf with path coeficient poi = 1.03367 and patial determination coefficient 102%. It was indicated that dried slice leaf was strongly affected by seventh leaf area with path coefficient p,n- 0.85257 and dried slice leaf strongly variable affected the crop index with path coeficient poi= 0.95639, while the grade index had little effect on crop index with path coefficient poi= 0.12316. The path analysis between leaf nicotine content and ive variables above was unfit with residual path coeficient pou= 0.6827, it was higher than each path coefficient of the orther variables. The dried slice leaf was the main independent variable affecting the crops index, so that selling of fresh tobacco leaves by farmers is not recomended.Key words : Nicotiana tabacum, Virginia tobacco, path analysis, leaf number, leaf area, crop index, grade index, nicotine content, dried slice leaf

Abstract

Effect offertilizer and pruning on growth, nutrient status, and productivity of caricature plant (Graphtophyllum pictum (L) Grif.)Information on the effect of fertilizer and top cutting application on growth, nutient uptake, and productivity of caricatue plant (Graphtophyllum pictum (L) GrifT.) was limited. Increasing demand for that crop in the future as traditional medicine should be back up by applicable agronomical informations of caicature plant. The objective of this study was to evaluate the effect of fertilizer and pruning applications on growth, nutrient uptake, and productivity of caricature plant. The pot trial was conducted at the Research Institute for Spices and Medicinal Crops from August 1997 to January 1998. A randomized block design was arranged with two factors and 3 replications. Each treatment consisted of 5 plants. The irst factor consisted of three shoot cutting periods . (I) control; (2) 2 months ater planting (MAP) and (3) 4 MAP. The second factor was 6 fertilizer combinations: (1)-N, -P, -K, and manue (M); (2) -N, +P +K. and +M; (3) . +N, -P, +K, and +M; (4) +N, +P, -K, and +M; (5) +N, +P, +K, and -M; (6) +N, +P, +K, and +M, respectively. It was consideed that there were significant interaction between fertilizer and pruning applications, especially on the gowth and productivity of caricatue plant. Application of NPK and manue impoved plant productivity and nutrient status. Pruning treatments wee able to increase leaves fresh weight signiicantly. The highest productivity of caicatue plant was found at the combination teatment of pruning and N, K, Manue fertilizer applications. Theefore, the optimal growth and productivity could be achieved by early pruning and fertilizer application, especially manure.

Abstract

Strong opinions have been expressed toward oil palm plantation industry in Indonesia, and these opinions portray that oil palm plantation development in Indonesia has caused the destruction of the environment. One of the efforts currently undertaken by the Indonesian government to ensure the sustainability of the palm oil industry is establishing sustainability standard called the Indonesian Sustainable Palm Oil (ISPO) which is mandatory. ISPO is "guidance" for sustainable oil palm development as well as a commitment based on the laws and regulations aplication of some licenses in Indonesia. The purpose of this study was to determine the capability of oil palm plantation companies in the regional to meet the standards of the Indonesian Sustainable Palm Oil (ISPO) and to identify the problems faced in achieving these standards. This research was conducted in East Kalimantan province on the period June 2012-May 2013. Evaluation of the capability of the companies to achieve the ISPO standards was performed by the audit method, assessment results of all parameters that had been established in accordance with the Principles, Criteria and Indicators in the provision of ISPO which were assessed in a percent unit. The research results showed that the capability of the plantation companies in East Kalimantan in meeting the ISPO standards reached 79,14%, and this capability can be improved up to 100% by increasing efforts to comply with the principles, criteria and indicators that are still not in accordance with the provisions of ISPO are as follows: 1). Licence system and plantation management, 2). Aplication guidance cultivation technics and processing palm fruit, 3). Management and monitoring invironment, 4). Resposibility to workers, and 5). Social resposibility and community. The determantion factor performance on ISPO standard is the commitment of plantation company as a business stakeholder that supported by capable human resources to create the sustainable plantation development and also the goverment action in charge as the regulator in supervising the policy that has been set. Socialization and training about principles and criteria ISPO standard to plantation company needs soon and more intensively done by the government association with ISPO commission to accelerate the application of the ISPO. Socialization and training also are required in order to overcome the constraints in attainment of principles and criteria of the Indonesian Sustainable Palm Oil standard, because of the mentioned efforts are the part of success factors to apply the ISPO.Keyword: ISPO, Management, Palm Oil, Plantations, Sustainable.

Abstract

The period of using plastic mulch on white grubs population and productivity of sugar cane at white grubs endemic area was conducted in Banyuputih Village, Situbondo on planting season of 2014/2015. Treatment consisted of 5 plastic mulch period (1) Before raining (SBH), (2) One day after rainfall, 14 mm (1 HSH), (3) Seven days after raining (7 HSH), (4) 14 days after raining (14 HSH), (5) 21 days after raining (21 HSH) and Control (without mulching plastic). Research using Randomized Block Design was repeated 5 times. Parameters observed in white grubs and adult (beetle), percentage of plant damage, productivity of sugar cane and sugar and rainfall data. The results showed that all plastic mulch period treatments significantly reduced white grubs population and crop damage compared with controls. Treatment of plastic mulch period of one and seven days after raining provides a difference in productivity of sugar cane of 83 tons/ha (7.7 tons/ha) and 96 tons/ha (sugar 7.8 tons/ha) above the control and both treatments can be recommended. This research needs to be continued especially to find out the efficiency of using plastic mulch in endemic white grubs area.Keywords: closing period, plastic mulch, white grubs control, population, sugarcane productivity AbstrakPenelitian untuk mengetahui periode penutupan tanah menggunakan mulsa plastik terhadap populasi uret dan produktivitas tebu dilaksanakan di areal endemik uret di Desa Banyuputih, Situbondo pada musim tanam 2014/2015.

Abstract

Biology of egg parasitoid ('Ooencyrtus malayensis Ferr.) ofpepper bug on alternate egg host (Nezara viridula L)Pepper bug (Dasynus piperis China) is an important pest of pepper. The pest widely spread in most pepper plantations of Indonesia. The level of the pest attack varied depended on crop cultivation treatment. Ooencyrtus malayensis is one of natural enemies which is able to control the population of pepper bug in plantation. The objective of this research was to study some aspects of the egg parasitoid biology by using eggs of Nezara viridula as the alternate host. This research was designed in a completely randomized block with four replicates. Dasynus piperis was collected from Bangka island and reared in Laboratory of the Research Institute for Spice and Medicinal Crops (RISMC ). Nezara viridula was fed with cowpea bean. This reascarch was conducted from July 1998 to February 1999. Experiment was divided into seven steps such as oviposition. pre adult period, production of parasitoid per host egg. egg preference, infestation period effect of cold storage (4°C) and parasitoid population. Research results showed that there were 85.5 parasitoid produced during its life time. Pre adult period lasted from 12 to 16 days, alternate host produced 3 parasitoids. The parasitoid pefeed the host of 0-2 days old. The eggs could be stored for 25 days in a efrigenerator (4°C). The longer the infestation and the larger number of parsitoid infested the larger numbers of parasitoid produced.

The formulation was obtained from FID Parry Ltd. (India), containing 1% azadirachtin A. The concentration recommended was 2-4 ml of formulation It of water or equal to 20-40 ppm of azadirachtin A The insects tested were obtained by reaing them in a screen house. Research was arranged in a completely randomized design, and randomized block design (for ovicidal). 6 treatments and 4-6 eplications. The treaments were concentrations of azadirachtin A (I) 80 ppm (2) 40 ppm (3) 20 ppm, (4) 10 ppm. (S) 5 ppm and (6) 0 ppm. Research consisted of three activities, i.e. effect of neem extract on (1) insect mortality and the survival rate. (2) as antifeedant, and (3) asovicidaon the insect. Results showed that azadirachtin A killed the insect slowly, it needed 3-10 days. Azadirachtin A acted as a growth inhibitor shown by the fact that at 5 and 10 ppm azadirachtin A, some pupae became malformed adults and other pupae died in a failed molt attempt Azadirachtin functioned as an antifeedant on some adult insects where the pupae were malformed and died on antifeedant and inhibit about 40% of feeding deference. Azadirachtin A also acted as an ovicidal inhibited about 50% egg-hatching.
