Kondisi pertumbuhan jumlah penduduk yang tinggi tidak hanya berpengaruh terhadap kebutuhan air atau pangan, melainkan dapat menyebabkan meningkatnya konversi lahan sebagai pemenuh kebutuhan hidup manusia. Adanya konversi kawasan lindung menjadi kawasan pertanian atau pemukiman mampu meningkatkan potensi kerusakan lingkungan. Tingkat kerusakan lingkungan memang tidak dapat dihindari atau tidak dapat di kontrol secara bersamaan, namun mampu dikurangi melalui perencanaan penggunaan lahan, pembangunan, serta manajemen yang baik. DAS Serang sebagai satu dari empat DAS kritis di Daerah Istimewa Yogyakarta yang menjadi bagian dari 108 DAS kritis di Indonesia perlu dilakukan kajian terkait sumberdaya lahan sebagai pendukung terciptanya perencanaan penggunaanlahan yang berkelanjutan. Penelitian ini dilakukan dengantujuan menganalisis kelas kemampuan lahan untuk mengetahui tingkat ketimpangan penggunaan lahan pada wilayah DAS Serang. Penenentuan kemampuan lahan menggunakan satuan bentuklahan sebagai unit analisis dengan membandingkan metode weight factor matching dan subjective factor matching. Metode tersebut merupakan bagian dari teknik pembandingan (matching) yang dilakukan dengan cara mencocokan dan membandingkan karakteristik lahan dan kriteria kelas kemampuan lahan. Hasil yang didapatkanmeliputi 14 bentuklahan dan 11 unit lahan yang analisis dengan kelas kemampuan I hingga VIII yang disajikan dalam peta dan gambaran spasial ketimpangan penggunaan lahan pada DAS Serang.

Tectona Grandis L.F

Land evaluation of a tract of land, for its suitability to be planted with a particular plantation species is an importantstep for species choice in plantation forest. A weight factor matching (WFM) approach of this study, was used to identifysuitable land for jati (Tectona grandis L.f) in PT. Melapi Timber, East Kalimantan. Land suitability is affected by climate,soil and topograph. According to WFM, the results indicated that important variables which limit T. grandis in theresearch area were pH, cation exchange capacity (CEC), potassium (P) and soil depth condition. The study results showthat 4 of 5 land units are marginally suitable (S3) for T. grandis cultivation in PT. Melapi Timber.Key words: Land evaluation, suitability, Tectona grandis L.f., weight factor matching (WFM)

We cannot be sure exactly what will happen, we can only estimate by using a particular method, where each method must have the formula to create a regression equation and a formula to calculate the confidence level of the estimated value. This paper conveys a method of estimating the future values, in which the formula for creating a regression equation is based on the assumption that the future value will depend on the difference of the past values divided by a weight factor which corresponding to the time span to the present, and the formula for calculating the level of confidence is to use "the Haryadi Index". The advantage of this method is to remain accurate regardless of the sample size and may ignore the past value that is considered irrelevant.

This paper presents a linguo-axiological analysis of French and Russian proverbs based on identifying value orientations and creating their hierarchy by studying the names and quantitative dominance of various thematic groups in authentic paroemiological dictionaries. Identification of value orientations allows us to reveal both common features of ethnic groups, which are of interest in the era of globalization and mutual influence of languages and cultures, and specific ones, contributing to the preservation of national identity. The novelty of this research compared to the author’s previous studies lies in the use of two additional lexicographic sources (one French and one Russian). The examined material of the four dictionaries includes more than 30,000 proverbial units. The analysis revealed the presence of a large number of common topics (which can occupy different positions in the value hierarchy of the ethnic groups under study) not only in dictionaries of the same language, but in all four sources. The names of the categories and their quantitative composition allow us to define French culture as individualist, while Russian culture, as collectivist. When constructing a hierarchy, it is important to turn to a larger number of dictionaries and identify common proverbial units in them to avoid the influence of the subjective factor, which is the case when naming and forming categories, as well as of the researcher’s individual approach to the proportion of category names to their corresponding values. The expanding vocabulary and studies on evaluativity in proverbs aiming to identify value and anti-value components within various topics can be used for further research.

The Relationship

With the increasing deployment of IoT devices and applications, a large number of devices that can sense and monitor the environment in IoT network are needed. This trend also brings great challenges, such as data explosion and energy insufficiency. This paper proposes a system that integrates mobile edge computing (MEC) technology and simultaneous wireless information and power transfer (SWIPT) technology to improve the service supply capability of WSN-assisted IoT applications. A novel optimization problem is formulated to minimize the total system energy consumption under the constraints of data transmission rate and transmitting power requirements by jointly considering power allocation, CPU frequency, offloading weight factor and energy harvest weight factor. Since the problem is non-convex, we propose a novel alternate group iteration optimization (AGIO) algorithm, which decomposes the original problem into three subproblems, and alternately optimizes each subproblem using the group interior point iterative algorithm. Numerical simulations validate that the energy consumption of our proposed design is much lower than the two benchmark algorithms. The relationship between system variables and energy consumption of the system is also discussed.

Factor Matching

Through analyzing the factors affecting passengers’ path-choice, the corresponding principles and rules of the ticket income distribution are put forward and the new model of the Urban Rail Transit Network in Beijing is set up in the paper. Through the deformation of the urban rail transit and the simplification of the lines, the topology of the urban rail transit lines is abstracted into an undirected connection graph. Breadth-priority optimization algorithm is applied to search the effective paths between the OD and the flow-matching ratio is acquired by calculating based on multi-factor matching algorithm, in which many relevant numerical examples are analyzed to verify the feasibility of the dual-ratio method and to summarize the characteristics of the project.
