Abstract

The research aims to know the life cycle, feeding and mating behavior of predatory beetle S.  gilvifrons, and was conducted at entomology laboratory of Assessment Institute for agri-cultural technology Malang - East Java. The treatments involved feeding behavior and capacity of the various instars and imago of S. gilvifrons. The number of mites consumed within 24 hours by each stage of beetle was also recorded. The average voracity of five individual predators for each instar was determined.  The result showed that average life cycle of S.  gilvifrons feed on E. orientalis was 4.11 + 0.78; 8 + 1.10; 3.83 + 0.41, respectively for egg, larva and pupa.  The predator caught the preys from the front side, then chewed and sucked the body contents of adult preys or consumed the whole egg.  The feeding capacity was greater in egg-laying than that in non egg-laying females and males.  The smallest size of the cage (1.5 cm diameter x 5 cm long) and clear weather were the most preferred situation for S.  gilvifrons mating, which  usually occurs on the upper leaf surface.  The male positioned itself over the female body and extended its aedeagus to reach the female.    Keywords: Life-history, Stethorus gilvifrons, phytophagous mites

Abstract

ABSTRAK. Penggerek batang merupakan masalah utama pada budidaya mangga di wilayah rendah basah. Informasimengenai hama ini masih sangat sedikit, sehingga upaya untuk mendapatkan teknologi pengendalian agak sulitdilakukan. Penelitian bertujuan untuk mengumpulkan data mengenai jenis penggerek, tingkat serangan OPT padabeberapa lokasi dan varietas mangga, serta eksplorasi untuk mendapatkan musuh alaminya. Penelitian dilakukandengan metode survai mulai Januari 2005 sampai dengan Desember 2006. Hasil penelitian menunjukkan bahwahama penggerek yang menyerang tanaman mangga di Sumatera Barat dan Sumatera Utara adalah Rhytidodera integra(Coleoptera: Cerambycidae) (Kolbe 1886). Selain didominasi jenis hama tersebut, di Kebun Percobaan Balai PenelitianTanaman Buah Tropika juga ditemukan jenis lain, yaitu spesies Palimna annulata Oliver (Coleoptera: Cerambycidae).Perilaku kedua jenis hama tersebut sama, yaitu menyerang mangga mulai dari pucuk kemudian menuju ke bagianbatang utama. Hama penggerek batang menyerang hampir semua varietas yang ditemui dan ditemukan di semuadaerah yang disurvai. Tingkat serangan rerata hama penggerek batang di Sumatera Barat 8,83% dan di Sumatera Utara10,36%. Varietas mangga yang terserang paling parah di Sumatera Barat adalah Cengkir (23,26%) dan di SumateraUtara adalah Podang (19,01%). Lima jenis agens pengendali biologi hama penggerek batang mangga ditemukanselama pelaksanaan survai. Hasil penelitian ini dapat digunakan sebagai informasi awal untuk menyusun teknologipengendalian hama penggerek batang mangga.ABSTRACT. Muryati, M. Istianto, and Affandi. 2010. Some Bioecological Aspects of Mango Stem Borer.Stem borer is the most important pest on mango in the wet lowland area. The information about this pest was stillvery limited, therefore, it is difficult to arrange its control strategy. The research were intended to collect data on thespecies of stem borer from some locations, its damage severity on some mango varieties as well as its natural enemies.The study was conducted by survey method from January 2005 to December 2006. The research revealed that thestem borer found in some locations was dominated by Rhytidodera integra (Coleoptera: Cerambycidae) (Kolbe 1886).Besides this species, another Cerambycidae, i.e. Palimna annulata Oliver was also found at Aripan Research Stationof Indonesian Tropical Fruit Research Institute. Both species have a similar behavior. The stem borer attacked almostall varieties that were found in research locations. The damage severity of mango by stem borer was 8.83 and 10.36%in West Sumatera and in North Sumatera, respectively. The most severe damage of mango variety in West Sumaterawas Cengkir (23.26%), while in North Sumatera was Podang (19.01%). Five species of natural enemies were foundduring the study. The results of this experiment can be used as initial information to control mango stem borer

Abstract

ABSTRACT The management of human resource in relation to private medical school independency: case study of medical educational unitsBackground: Most of the weaknesses of private medical schools in Indonesia are due to inappropriateness in the management of human resources. Medical Educational Unit (MEU) can be used to evaluate its role in the management of human resource. There is no information about what aspects of management in human resources have been implemented by MEU.Objection: To analyze the implementation of aspects contributed to the management of human resources by MEU.Method: This is a qualitative study to assess the implementation of the management of human resources in MEU. Data collected by in depth interview, observations, and document analysis in 4 (four) private medical schools in West Java. Data analysis was done by using koding, categorization and description.Results: The compensations for human resources in private Medical Schools in West Java is still inappropriate. Based on observations in the perspective of self-directing, self-motivating, self-regulating, self-supporting, self-assessing, and self-decision, this study showed the weaknesses in self-motivating, which can be seen in low level of achievement drive, commitment, inisiative, and optimism. Besides, there was no optimalization in the usefulness of information system technology.Conclusions and Suggestions: The perspective of to be autonomous in private medical schools in the aspects of MEU is still inappropriate. Therefore, the management of human resources in MEU is still to be increased.Keywords: MEU, Fakultas Kedokteran, ManajemenABSTRAKLatar belakang: Lemahnya kemandirian Fakultas Kedokteran (FK) Swasta di Indonesia umumnya berkaitan dengan lemahnya manajemen sumber daya manusia (SDM) dalam menyelenggarakan pendidikan. Salah satu aspek dalam manajemen pendidikan yang dapat dijadikan tolok ukur adalah peran Unit Pendidikan Kedokteran (Medical Education Unit/MEU) yang sudah dimiliki oleh setiap FK di Indonesia. Belum diketahui bagaimana manajemen SDM diimplementasikan oleh MEU.Tujuan: Menganalisis implementasi aspek-aspek yang berkontribusi terhadap manajemen SDM di MEU.Metode: Merupakan penelitian kualitatif dengan melakukan wawancara mendalam, observasi, dan analisis dokumen pada MEU di 4 FK Swasta di Jawa barat. Data dianalisis secara deskriptif.Hasil: Aspek kompensasi pada manajemen sumber daya manusia di FK Swasta di Jawa Barat masih kurang dari memadai. Ditinjau dari perspektif kemandirian perguruan tinggi swasta, yaitu dari aspek self-directing, self-motivating, self-regulating, self-supporting, self-assessing, dan self-decision, maka hasil pengamatan yang diperoleh adalah aspek self-motivating masih kurang memadai, hal ini terlihat dari tingkat achievement drive, komitmen, inisiatif dan tingkat optimisme yang dapat dikategorikan belum memuaskan. Penggunaan teknologi sistem informasi untuk mendukung proses pendidikan juga belum dilaksanakan secara optimal.Simpulan dan Saran: Perspektif kemandirian FK swasta dilihat dari aspek MEU masih sangat kurang, hal ini terlihat dari rendahnya tingkat achievement drive, komitmen, inisiatif maupun tingkat optimisme. Oleh karena itu, kemandirian FK swasta

Abstract

Synthesis of hydroxyapatite (HAp) from blood cockle shell (Anadara granosa) by hydrothermal process has been successfully done. The aim of this research was to get theoptimum process condition and also to investigate the influence of the Ca/P mole ratio and the synthesis temperature toward HAp characteristic. The powder of blood cockles shell wascalcined to get CaO which then was reacted with diammonium hydrogen phosphate by using water as solvent. Hydrothermal process was done by closed system in order to avoid thesolvent be lost while heating up above the solvent’s boiling point. The samples then were characterized by using FTIR (Fourier Transform Infrared), XRD (X-Ray Diffraction), andSEM (Scanning Electron Microscopy). The functional groups were observed in the FTIR of the synthesized HAp are phosphate (PO4 3-), hydroxyl (OH-), carbonate (CO3 2-), and hydrogenphosphate (HPO4 2-). These functional groups indicate that HAp has been formed. XRD data showed the main peaks for HAp that strenghtened the truth of FTIR characterization. SEM was used to observe the morphology of the synthesized HAp that consisted of agglomerates. Through analysis of the EDXA (Energy Dispersive X-Ray Analysis), the Ca/P mole ratio of the synthesized HAp could be counted where the result is 2. EDXA and SEM analysis were done together due to EDXA and SEM are one device. The best condition in this synthesis occured at Ca/P mole ratio 1,60 and the synthesis temperature 160oC.Keywords: blood cockle shell; hydroxyapatite; hydrothermal

Abstract

The research is aimed to confirm the potency of several botanical pesticides to be used as natural biological control and to know the most infective stadium of T. kanzawai was done at Pest and Disease Laboratory of Indonesian Tropical Fruits Research Institute from May to August 2009.  A factorial completely randomized design was used in this research.  Two factors were observed; first, four kinds of botanical pesticides consist of four treatment levels i.e. extracts of neem, soursop, Siam weed leaves and sterilized water as control.The second was the stadia of T. kanzawai that consist of three levels i.e. larva, nymph and adult.  The result showed that Siam weed and soursop leaves extracts caused anti-feedent behavior and decreased mobility at five days after treatment.  In addition, exoskeleton of treated T. kanzawai darkened from white, yellowish and bright brown.  Extracts of Sourshop and Siam weed leaves caused very high mortality (96.67%) of T. kanzawae compared to neem (79.17%).  However, there was no significant difference in mortality rates among the four active stadia of T. kanzawai with average mortality range from 65.63% to 79.38%. Keywords: botanical pesticide, T. kanzawai, control

Abstract

Mangosteen (Garcinia mangostana Linn.) dubbed as “finest fruit of the world”, has potential for both domestic market and export. However, this potential is threatened by low fruit quality caused by production of yellow latex and fruit scarring. The research objective was to obtain technology to reduce yellow latex and control Scirtothrips dorsalis, a pest that causes scarring on mangosteen. A randomized block design with four treatments and 14 replications was used in this research. Significant differences among the treatments were calculated using the Honestly Significant Difference (HSD) test. The results showed that treatment of drip irrigation system in combination with removing weeds under the canopy (A) or removing weeds followed by minimum tillage under the canopy (B) or removing weeds then covering with rice hay mulch under the canopy (C), where N, P, K, Ca, Mg fertilizer and yellow fluorescent sticky trap were applied could reduce scarring intensity and percentage of yellow latex on the fruit peel. However, the treatments did not significantly impact fruit diameter or percentage of yellow latex inside the fruit. Nevertheless, treatment C improved mangosteen quality by as much as 67.79% fulfilling export standard requirements.Keywords: Mangosteen, quality improvement, drip irrigation, yellow fluorescent sticky trap
