Abstract

SokoTunggal Islamic Boarding School Semarang has a very important role as a place to nurture religious tolerance for its students. The need for religious tolerance education is urgent because various conflicts in Indonesia are sourced from inter-religious issues. Religious tolerance education in Soko Sole Boarding School aims at nurturing mental and morals of the students in order to become a person with ahlakul karimah showed by tolerance to differences in people’s lives, especially religious differences. The results suggest the pesantren sucesfully conducts such program because the background of the Kyai , who is very tolerant, and the vision, mission and purpose of boarding school to teach the value of tolerance. Religious tolerance value is fostered through the habituation of students in interaction with people of other religions, the example of Kyai, and through learning, especially the books of morals. The factors that asupport the development of tolerance in the boarding school include: the competence of management, and the high motivation of the students. While inhibiting factor is the caretaker and students who also have other jobs so they are not always able to follow the activities of the boarding school and the damage of some infrastructure.

Abstract

Community Kaliglagah use customary law on sharing agreements, a tradition that have been passed down through generations. This study aims at knowing the implementation of the agreements. The research method used was qualitative research methods. The research indicates that the implementation of agreements on production sharing agreements for the Village Kaliglagah is only based on an agreement between the owners of fields and tenants, a verbal agreement in nature, based on trust, without witnesses, and not done in the presence of the authority. The people use “maro” system for rice grown in paddy fields and “mertelu” for rice grown in non-paddy fields. Production costs for the system “maro” such as seed, fertilizer, and harvest wage rates are shared. Other costs are borne by farmers themselves. For mertelu system, the cost of production are borne by farmers except the expenses for fertilizer costs are shared harvest labor wages. Term of the agreement is not clear and unequivocal.

Abstract

Masalah rute kendaraan (MRK) merupakan salah satu masalah keputusan yang memegang peranan penting dalam kegiatan transportasi dan distribusi dalam manajemen logistik. MRK terkait dengan penentuan rute-rute kendaraan yang meminimumkan total jarak yang ditempuh dengan memperhatikan pembatas-pembatas berikut: (1) tiap rute berawal dan berakhir di depot, (2) tiap kendaraan hanya melayani satu rute, (3) tiap pelanggan dilayani oleh satu rute, (4) seluruh pelanggan harus dilayani, dan (5) total muatan untuk tiap rute tidak melebihi kapasitas kendaraan. Dalam literatur, definisi ini merupakan definisi untuk MRK dasar atau klasik. Makalah ini membahas perluasan dari MRK dasar yang mencakup karakteristik-karakteristik berikut: (1) trip majemuk (TM), (2) jendela waktu (JW) dan (3) pengantaran-penjemputan simultan (AJS). Metode pemecahan berbasis algoritma genetika (AG) diusulkan untuk memecahkan MRK yang dibahas dalam makalah ini. AG yang diusulkan diuji-coba dengan menggunakan beberapa contoh hipotetik.AbstractVehicle routing problem (VRP) is one of decision problems having an important role in transportation and distribution activity in the logistic management. The VRP deals with determining vehicle routes that minimizes total distance by satisfying the following constraints: (1) each route starts and ends at the depot, (2) each vehicle serves only one route, (3) each costumer is served by one route, (4) all customers must be served, and (5) total load for each route does not exceed the vehicle capacity. In literature, this definition is the definition for the basic or classical VRP. This paper discusses an extension of the basic VRP including the following characteristics: (1)multiple trips (MT), (2) time windows (TW), and (3) simultaneous pickup-delivery (SPD). A solution method based on genetic algorithm (GA) is proposed to solve the VRP discussed in this papaer. The proposed GA is examined using some hypothetical instances.

Abstract

Hajj pilgrimage cost (Biaya Penyelenggaraan Ibadah Haji/BPIH) requires around IDR 14 trillion every year. BPIH consists of direct and indirect costs, in which the largest cost component is the airfare reaching 86% of pilgrim deposits in 2019. This study shows that there is BPIH inefficiency that is caused by the disorganized appointment of the embarkation points and the division of flight groups that does not optimize aircraft capacity and airport capabilities. Through the operation research approach, this study models optimization BPIH by determining regional allocations of the pilgrims to embarkation points. The study aims to provide an alternative decision making for the Ministry of Religion in implementing an embarkation zoning policy so that BPIH becomes more efficient, transparent, and free from corruption.

Abstract

Despite the growing interest in investigating learners’ corpora, surprisingly little research has been conducted on the language use of L2 writers and its relation to the gender and genres in writing. Therefore, this study was aimed to find out the variation of language use in different genres or gender in weblogs, one of popular modes of computer-mediated communication (CMC). The study was done by conducting multivariate analysis using R program to weblog entries from a sample balanced of author gender (female or male) and weblog genre (diary or filter). Taking linguistic preferential features by Argamon et al (2003) and Pennebaker (2011) as dependent variables, the effect of genres or gender toward the use of the features was analyzed. The results showed that significant effects of several features can be considered as predictors. Personal pronouns and hedges (I think, and I believe) were found as predictors for diary; while the indefinite articles a/an and numbers were found as predictors for filter. As for the different language use by gender, female predictors were personal pronoun, verbs, negation, certainty words, and hedges. Meanwhile, the indefinite articles a/an, numbers, and preposition were the predictors of male writers.
