Abstract

Stochastic programming problem is mathematical problem (linear, integer, mixed integer, and nonlinier) with stochastic element lies data. To get reasonable solution and optimal with its stochastic data is needed several method. Applicable method in trouble stochastic programming are L-Shape decomposition and lagrange decomposition. Each method can determine optimal solution to troubleshoots stochastic programming

Abstract

ABSTRAK B-aljabar adalah suatu himpunan tak kosong X dengan operasi biner  dan konstanta 0 yang memenuhi aksioma-aksioma tertentu. Suatu bentuk khusus dari B-aljabar adalah BM-aljabar. Adapun hubungan kedua aljabar tersebut, setiap BM-aljabar adalah B-aljabar dan setiap B-aljabar 0-komutatif adalah BM-aljabar. Konsep fq-derivasi telah dibahas di B-aljabar. Pada artikel ini, dibahas konsep fq-derivasi di BM-aljabar. Hasil penelitian yang diperoleh adalah mendefinisikan inside dan outside fq-derivasi di BM-aljabar dan menentukan sifat-sifatnya. Adapun definisi fq-derivasi di BM-aljabar ekuivalen dengan fq-derivasi di B-aljabar, namun pada sifat-sifatnya terdapat perbedaan, yaitu terdapat sifat fq-derivasi yang berlaku di BM-aljabar tetapi secara umum tidak berlaku di B-aljabar. ABSTRACTB-algebra is a non-empty set X with a constant 0 and binary operation satisfying certain axioms. A special form of B-algebra is BM-algebra. Their relationship are every BM-algebra is a B-algebra and every 0-commutative B-algebra is a BM-algebra.  The concept of fq-derivation in B-algebra is discussed. The results define inside and outside fq-derivations in BM-algebra and obtain related properties. Moreover, the definition of fq-derivation in BM-algebra is equivalent to fq-derivation in B-algebra, but there are differences in their properties, which is there are some properties of fq-derivation in BM-algebra, but generally don’t hold in B-algebra.

Abstract

 Abstrak            Akar-akar persamaan kuadrat  dapat ditentukan dengan 3 metode yaitu pemfaktoran, kuadrat sempurna dan rumus kuadrat. Apabila koefisien pada persamaan kuadrat bernilai besar, akar-akar persamaan kuadrat akan diselesaikan dengan menggunakan rumus kuadrat, karena koefisien yang besar biasanya sulit dilakukan dengan metode pemfaktoran. Pada artikel ini akan dibahas metode lain dalam menyelesaikan akar-akar persamaan kuadrat, yaitu metode transformasi dan metode dengan melibatkan nilai diskriminan persamaan kuadrat. Kata kunci: Persamaan Kuadrat, Akar-akar Persamaan kuadrat, Pemfaktoran

Abstract

The Polynomial Combinatorics comes from optimization problem combinatorial in form the nonlinear and integer programming. This paper present a condition such that the polynomial combinatorics has solution. Existence of optimum value will be found by restriction of decision variable and properties of feasible solution set or polyhedra.

Abstract

Underage marriages are marriages that occur where a man or woman who has not reached the age required by applicable law, that is, if the male has reached the age of 19 and the woman has reached the age of 16. The purpose of community service activities is to provide socialization and understanding to the public about the impact of early marriage in terms of legal, health and education aspects. This activity can also improve knowledge competence, skills, community motivation, and play a role in the formation of a prosperous family village development team. Data collection techniques carried out by interview, observation and document analysis. The results of this community service show the enthusiasm of the community to attend a series of activities, and the active role of the community is quite good. Improved understanding of the community is divided into 3 categories, namely, the village prosperous village development team, health development and Education development. Activities carried out continuously and continuously have a positive impact on community growth and development.

Abstract

There are several problems in the community with children in the fields of Education, Law and Health. There are still children under 18 years of age who are exploited as commercial sexual workers; children in conflict with the law, children aged 10-18 Years work in the informal sector, children who leave primary school before graduating or do not continue to the next level due to access and economy; adoption cases are carried out outside the standard population administration procedures; the discovery of stunted children. So, it is necessary to increase public understanding regarding child protection. One of those who have the responsibility of providing protection to children is the parent, the service program is carried out by providing material related to the role of parents and society in providing protection to children. The delivery of this material aims to provide an understanding of child protection in terms of education, law and health so that the public can understand the importance of protecting children. This service activity in Tambun Village can be said to be successful. There was a request from the participants to continue this activity. The people of Tambun Village hope that for further activities, further training is given regarding the skills needed by parents and the community. To increase community understanding, the WA Group was also created, whose members are parents who have participated in the Socialization program, this group aims to be a forum for communication between the Service Team and the local community.

Abstract

As we know, the life of the people of Tanjung Pauh Hamlet, Tanjung Belit Village, Rokan Hulu Regency is still fairly traditional. The problem discussed in this research is concerned with the sugar palm farmers in Tanjung Pauh hamlet. The palm sugar produced is very popular with consumers because of its pure taste without a mixture of preservatives or chemicals, and because the manufacturing process prioritizes quality. It's just that due to a shortage of sap water, the production of palm sugar in Tanjung Pauh hamlet can be said to be very little to meet the needs of the community itself. Therefore, we tried to do research by conducting a survey of the location of the palm trees, the location of the palm sugar making, and collecting data on the needs of the palm farmers in Tanjung Pauh hamlet. This study aims to provide guidance to the community of Tanjung Pauh hamlet as a hamlet that has the potential to develop income through improving the quality and marketing of palm sugar. We gave a little idea to the palm farmers in Tanjung Pauh hamlet to produce palm sugar, which is palm sugar which is usually in the form of blocks, which is now being innovated into the form of ant sugar, in order to attract consumers' attention to love palm sugar in Tanjung Pauh hamlet.

Abstract

Salah satu pengelolaan wisata yang penting adalah pengelolaan rute perjalanan wisata. Pengelolaan rute perjalanan wisata yang dilakukan adalah dengan meminimumkan total waktu perjalanan sehingga bisa meminimumkan total biaya perjalanan. Biaya perjalanan yang murah akan menarik minat wisatawan untuk berkunjung ke Riau. Peneliti tertarik mengkonstruksi model matematis rute perjalanan wisata di Riau sehingga diperoleh total waktu perjalanan dan total biaya perjalanan yang optimal. Meminimumkan rute perjalanan kendaraan tidak hanya meminimumkan jarak perjalanan, tetapi juga terdapat beberapa tujuan yang lain, seperti meminimumkan total waktu perjalanan, meminimumkan total biaya, memaksimalkan jumlah pelanggan yang dilayani, meminimumkan waktu distribusi, dan memaksimalkan kapasitas angkut kendaraan. Pengelolaan rute perjalanan wisata pada penelitian ini difokuskan untuk perjalanan darat. Wisatawan akan mengetahui berapa total waktu perjalanan dan total biaya perjalanan yang mereka perlukan ketika mengunjungi daerah-daerah wisata di Riau daratan. Model matematis dibuat dengan menggunakan pemrograman gol. Pemrograman gol dipilih karena pemrograman gol dinilai paling efektif untuk menyelesaikan masalah fungsi tujuan yang mempunyai lebih dari satu tujuan. Sehingga hal ini sesuai dengan tujuan penelitian ini yaitu meminimumkan total waktu perjalanan dan meminimumkan total biaya perjalanan

Abstract

This article discusses Zilmer's reserve of dual purpose life insurance. Zillmer reserve is one type of modified premium reserve that is calculated using prospective reserves and Zillmer level of , which is the difference from gross premium and net premium in the 1st policy year is greater than standard loading, so it is necessary to find a way for the loading to be smaller than standard loading. Furthermore, in determining Zilmer's reserves using cox-ingersoll-ross interest rate (CIR) which will be expressed in the form of discount vaktor by estimating two parameters through variance.
