Location of voltage sag source by using artificial neural network

Power quality (PQ) is a major concern for number of electrical equipment such as sophisticated electronics equipment, high efficiency variable speed drive (VSD) and power electronic controller. The most common power quality event is the voltage sag. The objective is to estimate the location of voltage sag source using ANN. In this paper, the multi-monitor based method is used. Based on the simulation results, the voltage deviation (VD) index of voltage sag is calculated and assigned as a training data for ANN. The Radial Basis Function Network (RBFN) is used due to its superior performances (lower training time and errors). The three types of performance analysis considered are coefficient of determination (R2), root mean square error (RMSE) and sum of square error (SSE). The RBFN is developed by using MATLAB software. The proposed method is tested on the CIVANLAR distribution test system and the Permas Jaya distribution network. The voltage sags are simulated using Power World software which is a common simulation tool for power system analysis. The asymmetrical fault namely line to ground (LG) fault, double line to ground (LLG) fault and line to line (LL) fault are applied in the simulation. Based on the simulation results of voltage sag analysis, the highest VD is contributed by LLG for both test systems. Based on the proposed RBFN results, the best performance analysis are R2, RMSE and SSE of 0.9999, 5.24E-04 and 3.90E-05, respectively. Based on the results, the highest VD shows the location of voltage sag source in that system. The proposed RBFN accurately identifies the location of voltage sag source for both test systems

Respons Fungsional Burung Pentet (Lanius SP.) terhadap Belalang Kembara (Locusta Migratoria Manilensis)

The functional response of predatory bird, Lanius sp. (Passeriformes: Laniidae) on migratory locust [Locusta migratoria manilensis (Orthoptera: Acrididae)] had been studied under restricted condition. The migratory locusts were reared in the green house. Second and fourth nymph instars along with adult stages of the migratory locust were used in this trial. Maximum feeding and functional response of the predatory bird against the migratory locust were determined. Research protocol used follows Holling\u27s model. Results showed that the maximum feeding of the predatory bird was very high i.e. against 2nd and 4th instars and adult of the locust were 2.75 preys/minute, 0.13 preys/minute, and 0.09 preys/minute; respectively. The relationship between predatory bird and migratory locust fitted with the Holling\u27 s type 2 functional response. The high feeding rate of the predatory bird revealed that the bird is a promising candidate of biological control agent on migratory locust.

Aktivitas Harian dan Preferensi Burung Predator Lanius SP. terhadap Hama Sexava Spp.

The objective research is to know the daily activities and preference of predatory birds Lanius sp. to several stages of Sexava spp. Ten predatory birds 12 to 14 months of age were bought at merchant bird in Yogyakarta. The study was conducted naturally under controlled condition in cages. Before the study was conducted the predatory birds were acclimatized for three days by feeding them cricket and gradually changed to Sexava spp. The young nymphs, old nymphs, adult male, and adult female of Sexava spp. were found at coconut plantation in Dumagin village became the new dietary of the predator. The result showed that Lanius sp. is a diurnal bird; the activities were dominated by hunting and preying (16.52%), followed by flying (6.53%), jumping (5.70%), and walking (4.58%). The Lanius sp. preferred to prey on significantly more nymphs of Sexava spp. than the adult. The birds prey proportionally on the young nymphs, old nymphs, male, and adult females for 50%, 41%, 5%, and 4%, respectively. Penelitian bertujuan untuk mengetahui aktivitas harian burung predator Lanius sp. dan preferensinya terhadap berbagai fase hama Sexava spp. Burung berumur 1–1,2 tahun sebanyak 10 ekor diperoleh dari pedagang burung di Yogyakarta. Kajian preferensi burung predator Lanius sp. terhadap belalang Sexava spp. dilakukan di bawah kondisi fisik alami dan terkontrol dalam kandang uji. Sebelum kajian dilakukan burung predator diaklimatisasi selama 3 hari dengan pakan jangkrik dan berangsur-angsur diganti dengan belalang Sexava spp. Belalang Sexava spp. stadia nimfa muda, nimfa tua, imago jantan, dan imago betina diperoleh dari kebun kelapa desa Dumagin, dipakai sebagai mangsa burung predator. Hasil kajian menunjukkan bahwa Lanius sp. termasuk burung diurnal; aktivitas siang hari didominasi berburu mangsa dan makan (16,52%), diikuti terbang (6,53%), melompat (5,70%), dan berjalan (4,58%). Lanius sp. Secara signifikan lebih memilih stadia nimfa dibandingkan imago belalang Sexava spp. Proporsi nimfa muda, nimfa tua, imago jantan, dan imago betina yang dimangsa berturut-turut yaitu 50%, 41%, 5%, dan 4%

Optimalization of Temperature to Control Araecerus Fasciculatus De Geer (Coleoptera: Anthribidae) on Nutmeg

The exported nutmeg of Indonesia is frequently affected by the coffee bean weevil, Araecerus fasciculatus de Geer (Coleoptera: Anthribidae), so that it should be fumigated prior to export. CH3Br is an effective fumigant as quarantine measure for export products for 24 h, but this fumigant has been prohibited. Therefore, air temperature treatment is one of the alternative strategies. This research was aimed to determine the optimum air temperature in controlling A. fasciculatus on nutmeg. Healthy nutmeg, infected and A. fasciculatus-containing nutmeg, as well as individual adults of A. fasciculatus were treated with air temperature of 30−70°C for 1−24 h. The optimum air temperature was the lowest temperature which could kill 100% of examined insects. The results showed that 100% mortality of A. fasciculatus adults outside nutmeg occurred at air temperature of 45°C for 12 h or 50°C for 6 h. Meanwhile, 100% mortality of life stadium of A. fasciculatus inside nutmeg happened at air temperature of 55°C for 24 h. The raising of air temperature at 30−50°C for 24 h decreased the water content of nutmeg from 5.59±0.25 to 3.79±0.24%. The increment of temperature from 50 to 55°C for 24 h reduced the weight of nutmeg from 5.20±0.72 to 5.04±0.70 g. Air temperature treatment at 45−50°C for 12−24 h could eliminate adults of A. fasciculatus on exported nutmeg and air temperature of 55°C for 24 h could remove all life stadia of A. fasciculatus within nutmeg. IntisariBiji pala ekspor Indonesia sering diserang oleh kumbang bubuk biji kopi, Araecerus fasciculatus de Geer (Coleoptera: Anthribidae), sehingga harus difumigasi sebelum diekspor. Tindakan karantina pada produk ekspor yang sering menggunakan CH3Br efektif selama 24 jam, namun fumigan ini sudah dilarang. Oleh karena itu, perlakuan suhu udara merupakan salah satu alternatifnya. Penelitian ini bertujuan untuk menentukan suhu udara optimal untuk mengendalikan A. fasciculatus pada biji pala. Biji pala yang sehat, biji pala yang terserang dan berisi serangga A. fasciculatus serta imago A. fasciculatus diperlakukan dengan suhu udara 30−70°C selama 1−24 jam. Suhu udara optimal yaitu suhu terendah yang dapat membunuh 100% serangga uji. Hasil penelitian menunjukkan bahwa 100% mortalitas imago A. fasciculatus di luar biji pala terjadi pada suhu udara 45°C selama 12 jam atau 50°C selama 6 jam. Sementara itu, mortalitas 100% stadia hidup A. fasciculatus di dalam biji pala terjadi pada suhu udara 55°C selama 24 jam. Kenaikan suhu udara 30−50°C selama 24 jam menurunkan kadar air biji pala dari 5,59±0,25 menjadi 3,79±0,24%. Peningkatan suhu dari 50 menjadi 55°C selama 24 jam menurunkan berat biji pala dari 5,20±0,72 menjadi 5,04±0,70 g. Perlakuan suhu udara 45−50°C selama 12−24 jam dapat mengeliminasi imago A. fasciculatus pada biji pala ekspor dan suhu udara 55°C selama 24 jam dapat mengeliminasi semua stadia hidup A. fasciculatus di dalam biji pala

Pengaruh Warna Perangkap Feromon terhadap Hasil Tangkapan Imago Oryctes Rhinoceros di Perkebunan Kelapa Sawit

The effectiveness of a synthetic-pheromone trap with active ingredient of ethyl-4-methyloctanoate in catching adults of Oryctes rhinoceros was believed to be influenced by the trap color. A RCBD trial with single factor and three block replicates was conducted during September to October 2008 at Oil-Palm-Trial Station at PTPN III, Labuhan Batu District, North-Sumatera Province. The single factor was trap color i.e. orange, green, white, blue, red, yellow, and pink. Results showed that total numbers and sex ratios of collected O. rhinoceros adults were not significantly influenced by the trap color. The total numbers of collected O. rhinoceros adult during 30 days on color of orange, green, white, blue, red, yellow, and pink were 136, 177, 126, 155, 129, 114, and 113 individuals with sex ratios ♂/♀ 0.47, 0.52, 0.62, 0.50, 0.60, 0.49, and 0.54, respectively. The synthetic pheromone significantly attracted more O. rhinoceros female (65%) rather than the male one (35%). Keefektifan perangkap feromon sintetik berbahan aktif ethyl-4-methyloctanoate dalam menangkap imago Oryctes rhinoceros diyakini dipengaruhi oleh warna perangkap tersebut. Percobaan RCBD faktor tunggal dengan tiga blok ulangan dilakukan pada bulan September sampai dengan Oktober 2008 di kebun penelitian kelapa sawit PTPN III, Kabupaten Labuhan Batu, Provinsi Sumatera Utara. Faktor tunggal tersebut yakni warna perangkap meliputi oranye, hijau, putih, biru, merah, kuning, dan pink. Hasil penelitian menunjukkan bahwa warna perangkap tidak berpengaruh signifikan terhadap hasil tangkapan dan sex ratio imago O. rhinoceros. Total imago O. rhinoceros yang tertangkap selama 30 hari pada warna oranye, hijau, putih, biru, merah, kuning dan pink sebanyak 136, 177, 126, 155, 129, 114 dan 113 dengan sex ratio ♂/♀ 0,47; 0,52; 0,62; 0,50; 0,60; 0,49 dan 0,54. Feromon sintetik secara signifikan lebih banyak menarik imago betina (65%) daripada yang jantan (35%)
