Conjunction Weighted Average Method with Fuzzy Expert System for Weather Event Forecasting – A Monthly Outlook
Fuzzy logic as a limiting case of approximate reasoning is viewed in exact reasoning, consider everything in a matter of degree. A collection of elastic or equivalently interpreted to knowledge, a collection of variables in fuzzy constraint. Inference is process as a propagation of elastic constraints. Every logical system is fuzzified in fuzzy logic. Fuzzy logic is fascinating area of research, it trading off between significance and precision. It is convenient way to map space of input to a space of output. Fuzzy logic as so far as the laws of Mathematics refers to reality, they are not certain and so far, as they are certain as complexity rises, precise statements lose meaning and meaningful statements lose precision. Most meteorological infrastructure is surprisingly versatile. For example, the same radar system that can detect oncoming storms will also be useful for gathering general rainfall data for the farming sector. Being able to predict and forecast the weather also allows for data to be gathered to build up a more detailed picture of a nation’s climate, and trends within i
Efficacy ofEuphorbia milli and Euphorbia pulcherrima on aflatoxin producing fungi (Aspergillus flavus and Aspergillus parasiticus)
Efficacy of seven different concentrations (5, 10, 15, 20, 25, 30 and 35 mg/ml) of dry flower powder of Euphorbia milli and Euphorbia pulcherrima was tested on the growth of aflatoxin producing toxigenic strains of fungi’ Aspergillus flavus and Aspergillus parasiticus in Sabouraud Dextrose Agar medium (SDA). Total (100%) inhibition of growth of both A. flavus and A. parasiticus was observed at 30 mg/ml concentration of E. milli dry flower powder. Total inhibition (100%) of growth of A. flavus was observedat 30 mg/ml concentration of E. pulcherrima and for A. parasiticus, it is 35 mg/ml. Bioassay with groundnut seeds soaked with different concentration (5 – 35 mg/ml) of flower extract proved that both fungi were incapable of infecting the seeds in the presence of 30 and 35 mg/ml of both E. milli and E. pulcherrima
Aplikasi Alarm Weker Berbasis Android Dengan Algoritma Fisher Yates Shuffle Untuk Mengacak Pertanyaan
Tujuan dari pembangunan aplikasi ini adalah untuk membuat aplikasi berbasis android yang dapat membuat sekaligus mengacak pertanyaan Matematika sebagai syarat menghentikan alarm pada aplikasi weker. Untuk pengembangannya, penulis menggunakan pendekatan model Waterfall yang terdapat lima tahap yaitu: analysis, design, coding, testing dan maintenance, dengan bahasa pemrograman Java. Algoritma Fisher Yates Shuffle menentukan operand dan operator secara acak, sehingga pertanyaan yang disajikan merupakan kombinasi antara operand dan operator yaitu dari angka 0 hingga angka 99 dan terdapat operasi hitung penjumlahan, pengurangan, perkalian serta pembagian yang dibentuk secara acak. Berdasarkan metode pengujian Black Box disimpulkan bahwa aplikasi yang dibangun dapat berjalan sesuai dengan rancangan
Characterizing multiparticle entanglement in symmetric N-qubit states via negativity of covariance matrices
We show that higher order inter-group correlations involving even number of qubits are necessarily positive semidefinite for separable symmetric N qubit states. This identification leads to a family of inseparability conditions based on the negativity of 2kth order inter-group covariance matrices of symmetric N-qubit systems. These conditions have a simple structure and detect multiparty entanglement in both pure and mixed symmetric multiqubit states. The correlation observables involved are feasible experimental quantities and do not demand full state determination through quantum state tomography

Ikan layur (Trichiurus sp) merupakan ikan ekonomis penting di Pelabuhan Perikanan Nusantara Palabuhanratu. Pancing ulur merupakan alat tangkap dominan yang digunakan dalam menangkap ikan layur. Total produksi ikan layur (Trichiurus sp) pada tahun 2013 sebesar 83.936 kg. Harga merupakan salah satu penentu keberhasilan karena harga menentukan seberapa besar keuntungan yang akan diperoleh dari penjualan produknya baik berupa barang maupun jasa. Tujuan dari penelitian ini adalah adalah identifikasi distribusi pemasaran ikan layur (Trichiurus sp), menganalisis faktor-faktor yang mempengaruhi harga ikan layur (Trichiurus sp) dan menganalisis faktor-faktor yang paling berpengaruh terhadap pembentukan harga ikan layur di Pelabuhan Perikanan Nusantara Palabuhanratu. Penelitian ini dilaksanakan pada bulan Januari – Februari 2014 di PPN Palabuhanratu, Jawa Barat. Metode yang digunakan adalah metode studi kasus yang bersifat deskriptif, dimana data yang mula-mula disusun, dijelaskan dan kemudian dianalisa. Metode pengambilan sampel menggunakan metode purposive sampling. Analisis data yang digunakan adalah regresi linier berganda dan korelasi linier berganda. Hasil penelitian menunjukkan bahwa faktor-faktor yang mempengaruhi harga ikan layur (Trichiurus sp) adalah jumlah produksi, mutu dan berat ikan layur. Hairtail (Trichiurus sp) is one of an economical and important fish at Palabuhanratu Fishing Port. The most dominant fishing gear using handline for catching hairtail. The total production of hairtail (Trichiurus sp) in 2013 is equal to 83.936 kg. Price is one of the indicators to determine the success because the price influences the profit of the product selling, either for selling goods or providing service.

Tinjauan terhadap Eksistensi Hak Ulayat di Minangkabau (Studi Kasus di Kenagarian Sungai Antuan Kecamatan Mungka, Kabupaten Lima Puluh Kota, Sumatera Barat)
Communal land ownership is an important part of customary rights and is a very important factor in the life of Indonesian society, as well as indigenous people in West Sumatra that most of the population lives and livelihoods depend on the land. Article 3 of Law No. 5 of 1960 on Basic Regulation of Agrarian, containing a statement of recognition of the existence of customary rights of indigenous communities along by the fact still exist, meaning when in reality does not exist, then the customary rights that will not be turned on again, and will not be created new customary rights. According to the Customary Law Minangkabau communal land should not be traded, according to the slogan that live in Minangkabau society. But in reality there is still a violation of the rules of the customs. the purpose of the research is to know how the existence of customary rights in Kenagarian Antuan River, District Mungka, District Fifty City, West Sumatra, and how the role of the prince and Ninik Mamak and density Adat (KAN) customary rights in dispute resolution in Minangkabau. This research was conducted by using a sociological approach to research that want to see the correlation between law and society, with the specification in the form of descriptive research through library research. Based on this research, the existence of customary rights in Kenagarian Antuan River, District Mungka, District Fifty City, West Sumatra, began to weaken and occur several cases of customary rights, the role of Ninik Mamak, the prince is also not optimal because still there is a violation of their decision. Supposedly indigenous peoples and indigenous leaders to work together to protect customary rights, and people are given direction on customary rights and the role of traditional leaders should be optimized again.Keywords : Land Rights - Communal Land - Existence - Customary La
IN VITRO EVALUATION OF ANTHELMINTIC ACTIVITY OF AQUEOUS EXTRACT OF ARDISIA COLORATA ROXB. LEAVES IN ADULT EARTHWORMS
Objective: The study aims to evaluate the anthelmintic activity of aqueous extract of Ardisia colorata Roxb. leaves (AQEAC) using adult earthworms (Pheretima posthuman).
Methods: The total of 24 adult earthworms were divided into four groups, with six worms in each group (n=6). The anthelmintic activity of AQEAC at two different doses (25 mg/ml and 50 mg/ml) was evaluated by assessing the time of paralysis (min) and time of death (min) of the earthworms. Albendazole (25 mg/ml) was used as standard and 2% gum acacia as control.
Results: The result showed that AQEAChad significant anthelmintic activity (p<0.001) in a dose-dependent manner but was less potent than the standard drug albendazole.
Conclusion: AQEAC demonstrated significant anthelmintic activity but was less potent than the standard drug albendazole. However, further studies with higher doses are required to evaluate the dose-dependent activity and to evaluate the exact mechanism responsible for anthelmintic activity
