It is generally known that almost all filled function methods for one-dimensional unconstrained global optimization problems have computational weaknesses. This paper introduces a relatively new parameter free filled function, which creates a non-ascending bridge from any local isolated minimizer to other first local isolated minimizer with lower or equal function value. The algorithm’s unprecedented function can be used to determine all extreme and inflection points between the two considered consecutive local isolated minimizers. The proposed method never fails to carry out its job. The results of the several testing examples have shown the capability and efficiency of this algorithm while at the same time, proving that the computational weaknesses of the filled function methods can be overcomed.

This paper applies Fuzzy QFD in determing priorities of the interconnection tariff regulation which will be implemented by the government through the Ministry of Communication and Informatics. QFD is a method to translate customer satisfaction into strategic actions. This method is used in this paper to determine the priorities so that regulations set by the government can answer operators and end users satisfactions. QFD implements matrix approach known as the House of Quality (HOQ). The use of fuzzy logic is intended as an effective method to deal with the high level of subjectivity when using HOQ. In the first step we will generate a priority scale based on level of importance from the aspects of interests of the operators using TOPSIS. The aim of employing TOPSIS is to overcome the gap between the current state and the ideal conditions. In the second step we use the utility factor for determining a ranking of regulation elements. The use of Fuzzy QFD method proves the effectiveness in converting qualitative into quantitative assessment so that the results of the research in this paper can be used by regulators to determining priorities when implementing the new regulations.Makalah ini mengaplikasikan metode Fuzzy QFD dalam membuat skala prioritas pada butir-butir penyempurnaan regulasi tarif dan interkoneksi yang akan diimplementasikan pemerintah melalui kementerian komunikasi dan informatika. QFD, yang merupakan metode untuk menterjemahkan kepuasan pelanggan ke dalam langkah-langkah strategis penentu kebijakan, digunakan dalam penelitian ini untuk membuat prioritas sehingga diharapkan regulasi yang akan ditetapkan pemerintah menjawab kepentingan-kepentingan pihak penyelenggara maupun pelanggan (end users). QFD menggunakan pendekatan matriks yang lebih dikenal sebagai House of Quality (HOQ). Penggunaan logika fuzzy dimaksudkan sebagai metode yang efektif untuk menangani tingginya tingkat subjektifitas ketika menggunakan HOQ. Dalam langkah pertama, dibuat skala prioritas berdasarkan tingkat kepentingan dari aspek-aspek kepentingan pihak penyelenggara dengan menggunakan TOPSIS dimana tujuan dari penggunaan TOPSIS ini untuk mengatasi gap antara kondisi saat ini dengan kondisi idealnya. Langkah kedua menggunakan faktor utilitas fuzzy untuk perankingan butir-butir regulasi dari pihak regulator. Penggunaan metode Fuzzy QFD terbukti efektif dalam mengkonversi penilaian kualitatif menjadi kuantitatif sehingga hasil dari penelitian dalam makalah ini dapat digunakan oleh regulator untuk menentukan prioritas dalam mengimplementasikan regulasi baru.

This paper provides a new approach in combining the quality of some ministry websites through quantitative and qualitative approach. Quantitative data are obtained by performing measurement using web diagnostic tools while the qualitative approach is carried out through expert judgement. Then the weights will be calculated from the data obtained both quantitatively and qualitatively by applying linear weightage for quantitative data and using consistent fuzzy preference relations method for qualitative data. In the final stage, those two methods will be combined so that we will obtain the final weights which are the representation of the quality of websites measured.The results obtained by this research can be considered by the relevant ministry to develop their websites.Artikel ini memberikan pendekatan baru dalam membandingkan kualitas beberapa laman kementerian RI melalui pendekatan kuantitatif dan kualitatif. Data kuantitatif didapatkan dengan melakukan pengukuran menggunakan web diagnostic software sedangkan pendekatan kualitatif dilakukan melalui expert judgement. Data yang didapatkan baik secara kuantitatif maupun kualitatif akan dihitung bobot (weight) dengan mengaplikasikan metode linear weightage. Data kualitatif dengan metode consistent fuzzy preference relations digunakan untuk menghitung bobot dari expert judgement yang telah didapatkan. Kemudian kedua metode tersebut akan dikombinasikan sehingga akan didapatkan bobot akhir yang merupakan representasi dari kualitas website yang telah diukur. Hasil pembobotan yang didapatkan dalam penelitian ini dapat dijadikan rujukan dan pertimbangan untuk pihak kementrian terkait untuk melakukan pengembangan website yang dikelolanya.

Converging Newton’s Method With An Inflection Point of A Function Ridwan Pandiya; Ismail Bin Mohd

For long periods of time, mathematics researchers struggled in obtaining the appropriate starting point when implementing root finding methods, and one of the most famous and applicable is Newton’s method. This iterative method produces sequence that converges to a desired solution with the assumption that the starting point is close enough to a solution. The word “close enough” indicates that we actually do not have any idea how close the initial point needed so that this point can bring into a convergent iteration. This paper comes to answer that question through analyzing the relationship between inflection points of one-dimensional non-linear function with the convergence of Newton’s method. Our purpose is to illustrate that the neighborhood of an inflection point of a function never fails to bring the Newton’s method convergent to a desired solution

Law No. 36 of 1999 concerning Telecommunication has brought many changes, especially in the development of telecommunications infrastructure in Indonesia. However, the penetration of telecommunications services in the forefront, outermost, and backward regions is still relatively low. The government has made various efforts in terms of minimizing the gap in telecommunication services between urban and rural areas through various programs. However, an acceleration is needed so that the service disparity can be immediately overcome. One of the telecommunications products that can be applied to overcome these barriers is the Mobile Virtual Network Operator (MVNO). This study evaluates the most appropriate type of MVNO model to be applied in Indonesia by implementing the Consistent Fuzzy Preference Relations (CFPR) method. This method is able to accommodate expert opinion through a series of scientific steps so as to produce weights for each alternative type of MVNO model. The results obtained are that the most appropriate model to be applied in Indonesia by taking into account the criteria given. The implementation of this model is expected to be able to encourage the optimization of BTS USO that has been declared by the government.

Transparansi pelayanan telekomunikasi merupakan amanat yang tertuang dalam Undang-Undang Nomor 36 tahun 1999. Pentarifan interkoneksi bukan lagi hanya terpaku pada layanan voice dan sms saja, karena karakteristik pengguna layanan saat ini bergerak ke arah layanan data. Model pentarifan yang saat ini digunakan dalam menentukan tarif interkoneksi pada dasarnya diperuntukkan bagi layanan voice dan sms, sehingga model tersebut belum tentu sesuai jika diaplikasikan pada layanan berbasis Internet Protokol (IP). Penelitian ini merupakan evaluasi dari model-model yang tersedia dalam menentukan model yang paling efektif untuk digunakan dalam layanan berbasis IP. Penelitian ini menerapkan metode Consistent Fuzzy Preference Relations (CFPR) untuk menentukan alternatif terbaik dari model pentarifan interkoneksi berbasis IP. Metode CFPR, yang merupakan modifikasi dari metode Analytical Hierarchy Process (AHP), menjamin konsistensi matriks perbandingan berbagai kriteria ketika menggunakan AHP. Sehingga alternatif model pentarifan interkoneksi yang dihasilkan dalam penelitian ini dapat dijadikan rujukan pihak regulator tanpa meragukan konsitensi dari perbandingan kriteria-kriterianya. Berhadasarkan pengolahan data, model Pentarifan Interkoneksi Berbasis Internet Protokol yang paling disarankan adalah Bottom up -Long Run Average Incremental Cost (BU-LRAIC). Hal ini dikarenakan model tersebut memenuhi kriteria sangat baik dan fair secara teknikal, ekonomi maupun dampak social yang dihasilkan.

Teknologi informasi dan komunikasi (TIK) telah jamak dimanfaatkan oleh masyarakat, salah satunya adalah website, termasuk pada tata kelola pemerintahan. Instruksi Presiden Nomor 3 Tahun 2003 menyebutkan penyelenggaraan fungsi pemerintahan dapat memanfaatkan TIK, tidak terkecuali pada struktur pemerintahan terkecil, yaitu desa. Namun demikian, website desa pada umumnya memiliki kualitas kinerja yang rendah, serta kualitas konten yang kurang memadai. Sehingga, perlu ada rekomendasi terhadap kekurangan website desa agar kualitasnya dapat ditingkatkan. Penelitian ini mengambil objek website Desa Melung dan Desa Dermaji. Kinerja website diamati dan diukur selama 30 hari pada 7 kriteria uji sebagai variabel penelitian yaitu loading time (k1), page size (k2), brokenlink (k3), backlink (k4), web traffic (k5), page request (k6), dan performance grade (k7). Sedangkan kualitas konten diukur menggunakan kuesioner pada 7 aspek yaitu Identitas Nasional (a1), Pengelola (a2), Konten (a3), Tipografi (a4), Navigasi (a5), Teknologi (a6), Kemanan Informasi (a7). Berdasarkan hasil perbandingan kedua website menggunakan uji Mann Whitney, variabel loading time (k1) mendapatkan nilai signifikansi 0,287 yang berarti tidak terdapat perbedaan. Hasil uji pada variabel page size (k2), brokenlink (k3), backlink (k4), web traffic (k5), page request (k6),bernilai 0,000 atau dapat dikatakan terdapat perbedaan yang signifikan. Kualitas konten website Desa Dermaji lebih unggul yaitu mendapatkan nilai rata-rata 2,332 daripada website Desa Melung mendapatkan nilai rata-rata 2,237. Secara umum dapat dikatakan bahwa hasil performance total kedua website kurang baik, sehingga perlu ditingkatkan pada perbaikan link-link yang rusak, pengurangan ukuran halaman, penambahan tautan pada website lain atau sosial media. Aspek konten yang perlu diperbaiki antara lain pemenuhan kebutuhan informasi oleh masyarakat yang update, relevan dan akurat, sehingga perlu diunggah secara berkala.
