Komunikasi Pada Lembaga Pendidikan Nonformal

: Communications in Non-Formal Education Institutions. This multi-site qualitative study aims at describing the process of communication using kato mandaki, kato manurun, kato mandata, and kato malereng in the formal and informal communication network among the employers of nonformal edu­cation institutions. A modified analytical induction method was used to analyze the data collected from three Sanggar Kegiatan Belajar (Learning-Activity Centers) in Minangkabau region through in-depth inter­views and participatory observation. The findings show that the uses of kato manurun, kato mandaki, kato mandata, and kato melereng in both formal and informal communications in the three institutions under study depend on the communication purposes, social relationship between people communicating, and the degree of formality in the communication contexts

The Uptake of 32P by Brown Planthoppers (Nilaparvata Lugens Stal) Gonads

Abstract. The radioisotop 32P has been used quite extensively in the field of insect ecology and insect physiology. It has been widely known that 32P is one of the several isotopes applied to tag the insects for migration studies, to estimate the sap uptake or the excretion of sucking insects as well as for the study of sperms transfer in sterilization study. Within the scope of Sterile Insects Techniques, the study on the uptake of 32P by the gonads of brown planthoppers (Nilaparvata lugens Stal) could be meaningful. The 32P radioisotopes used had been one of most available products of the Centre. The radioisotope provided also a possible source for sterilization due to its accumulative effect. Results of the investigation on the 32P uptake by the whole body and gonads after feeding on radioactive rice seedlings will be reported.a. Absorption of 32PP by rice seedling ( Pelita I/1 )The specific activities of 32PP (Carrier free) applied to the two week old seedlings were 1, 2, 4, 6, 8, 10, 15, and 20 uci/cc. The radioactivity count of hoppers and leaf tips were made 48 hrs. after submersion of the seedlings in the radioactive solution.b. Absorption of 32PP by BPHThe radioactive seedlings were offered to BPH after being washed thoroughly with water. A single BPH is fed on a single rice seedlings kept in a glass tube. Count of the whole body and dissected gonads were made 24, 48, 72, and 96 hours after feeding. Sterility effects were observed from the mating of 32P treated hoppers. Sari. Radioisotop 32p telah dipergunakan secara luas dalam bidang ekologi dan fisiologi serangga. Telah diketahui secara luas bahwa 32Pp merupakan salah satu dari beberapa isotop yang telah dipergunakan untuk penandaan serangga guna menunjang studi migrasi, pengambilan cairan tanaman ataupun ekskresi dari serangga penghisap ataupun studi tentang transfer dari sperma. Didalam ruangan lingkup Teknik Serangga Mandul, studi dari pengambilan 32p oleh gonad dari wereng coklat (Nilaparvata lugens Stal) dapat mempunyai arti penting mengingat bahwa produk ini merupakan salah satu hasil yang mudah diperoleh dari PPTN dan mempunyai prospek yang baik sebagai sumber sterilisasi internat mengingat pengaruh akumulatipnya. Berikut adalah hasil penelitian tentang pengambilan 32P oleh seluruh tubuh dan gonad wereng setelah diberi makan benih padi yang radioaktip.a. Absorbsi 32P oleh benih padi (Pelita I/1)Aktivitas jenis dari 32P (bebas pengemban) yang dipergunakan untuk penandaan benih padi berumur 2 minggu adalah 1,2,4,6,8,10,15 dan 20 uci/cc. pencacahan terhadap ujung daun dan wereng dilakukan setelah akar benih padi direndam dalam larutan radioaktip selama 48 jam.b. Absorbsi 32P oleh wereng coklatBenih padi yang telah radioaktip dumpankan kepada wereng coklat setelah dicuci bersih dengan air suling.Satu wereng coklat dewasa diberi makan satu benih padi di dalam sebuah tabung kaca. Pencacahan dari tubuh dan gonad wereng yang telah dikeluarkan dilakukan 24, 48, 72, dan 96 jam setelah makan. Efek pemandulan diamati dari perkawinan wereng yang telah mendapat perlakuan 32P

A user oriented microcomputer facility for designing linear quadratic Gaussian feedback compensators

A laboratory design facility for digital microprocessor implementation of linear-quadratic-Gaussian feedback compensators is described. Outputs from user interactive programs for solving infinite time horizon LQ regulator and Kalman filter problems were conditioned for implementation on the laboratory microcomputer system. The software consisted of two parts: an offline high-level program for solving the LQ Ricatti equations and generating associated feedback and filter gains and a cross compiler/macro assembler which generates object code for the target microprocessor system. A PDP 11/70 with a UNIX operating system was used for all high level program and data management, and the target microprocessor system is an Intel MDS (8080-based processor). Application to the control of a two dimensional inverted pendulum is presented and issues in expanding the design/prototyping system to other target machine architectures are discussed
