Tunagrahita merupakan salah satu jenis disabilitas yang membuat penyandangnya memiliki inteligensi jauh di bawah rata-rata serta kemampuan bina bantu diri yang terbatas. Hambatan tersebut membuat anak tunagrahita menjadi kurang mandiri sehingga orang tua harus memberikan perhatian serta bantuan yang lebih besar dibandingkan dengan anak pada umumnya. Hal inilah yang dapat menjadi stressor bagi keluarga terutama ibu yang merupakan caregiver utama pada anak karena ibulah yang paling banyak meluangkan waktu untuk pengasuhan sang anak. Oleh karena itu dibutuhkan ketangguhan keluarga dalam menghadapi masalah terkait kehadiran anak tunagrahita. Resiliensi keluarga dianggap sukses bila keluarga dapat bertahan dari kesulitan dan mengambil makna dari kesulitan yang dihadapi. Salah satu cara untuk dapat resilien adalah dengan mengembangkan pandangan positif saat menghadapi masalah yang disebut juga sebagai koherensi keluarga. Penelitian ini bertujuan untuk mengetahui sejauh mana peran koherensi keluarga terhadap resiliensi keluarga yang memiliki anak tunagrahita dari perspektif ibu. Partisipan pada penelitian ini sebanyak 60 orang ibu yang memiliki anak tunagrahita, berdomisili di wilayah Jakarta, Bogor, Depok, Tangerang, dan Bekasi yang dipilih menggunakan metode  purposive sampling ­. Alat ukur yang digunakan yaitu Walsh Family Resilience Questionnaire (WFRQ) untuk mengukur resiliensi keluarga dan Family Sense of Coherence Scale (FSOCS) untuk mengukur family sense of coherence. Berdasarkan hasil uji regresi, didapatkan hasil bahwa family sense of coherence berperan secara signifikan (p 0,05) terhadap resiliensi keluarga (R-square= 0,235). Hal ini berarti koherensi keluarga berperan sebesar 23,5% terhadap resiliensi keluarga dan 76,5% lainnya dipengaruhi oleh faktor lain. Terkait dengan hal ini, upaya meningkatkan resiliensi keluarga dapat dilakukan dengan membantu keluarga mengembangkan perspektif positif dalam melihat situasi yang terjadi, menumbuhkan optimisme, dan mengedukasi keluarga untuk dapat memanfaatkan sumber daya di sekitarnya untuk membantu atasi situasi. Intellectual disability is the one of disability in which the individu has intellectual far below the average, and limitation in activity daily living. This limitation makes the children with intellectual disability have low autonomy cause parents should give care and assitaant more then usual. This condition can be the one of stressor for family, especially for the mother as caregiver who give more time to practice parenting for their children. So, family resillience is very important to face the emergence of intellectual disability children in family. In order to be resillient, a family should have positive perspective when facing the problem, called sense of coherence. The purpose of this research is finding the role of family sense of coherence towards family resillience among family who has intellectual disability children. The participant of this research is 60 mothers who have intellectual disability children and live in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek). The participants is selected by using purposive sampling method. This research uesd Family Resilience Questionnaire (WFRQ) to measure family resillience, and Family Sense of Coherence Scale (FSOCS) to measure family sense of corerence. Based on regression test, family sense of corerence has significant role towards family resilience (R Square = 0,235, p 0,05). It meanse that family sense of coherence gives contribution about 23,5 % to family resillience, and 76,5 % influenced by another factors. As the conslusion, family can be more resillient if it develops positive perspective when facing problem, build optimism, and use every resources wisely in order to solve problem.

ABSTRAK: Perairan Kaliboyo merupakan daerah yang berpotensi mengalami pendangkalan akibat pengendapan sedimen tersuspensi. Potensi dari pengdangkalan tersebut dapat diketahui dengan mengetahui nilai konsentrasi dan sebaran Material Padatan Tersuspensi (MPT). Konsentrasi MPT yang tinggi di laut dipengaruhi oleh arus yang dibangkitkan oleh pasang surut. Tujuan dilakukannya penelitian ini adalah untuk mengetahui pengaruh arus laut terhadap konsentrasi dan sebaran MPT di Perairan Kaliboyo Kabupaten Batang, Jawa Tengah. Materi yang digunakan meliputi utama berupa data sampel air dan arus laut sedangkan data pendukung berupa data pasang surut BMKG, dan debit sungai PSDA Jawa Tengah tahun 2017, bathimetri hasil pemeruman tanggal 15 September 2018, dan peta RBI 2017. Penelitian ini menggunakan metode kuantitatif yang bersifat eksploratif, penentuan lokasi pengambilan sampel air menggunakan metode purposive sampling, pengambilan data arus laut menggunakan metode lagrange. Model matematik yang digunakan adalah Flow Flexible Mesh Model 2D untuk arah pergerakan arus dan Inverse Distance  Weighted  untuk interpolasi sebaran MPT.  Berdasarkan hasil dari penelitian menunjukkan bahwa nilai material padatan tersuspensi pasang menuju surut pada kedalaman 0.2d memiliki nilai antara 0,027 g/l – 0.114 g/l, kedalaman 0.6d memiliki nilai antara 0,030 g/l – 0,114 g/l, dan kedalaman 0.8d memiliki nilai antara 0,038 g/l – 0,118 g/l. Kecepatan arus memiliki nilai antara 0.0181 m/dt – 0.2011 m/dt dengan arah dominan ke arah barat laut. Berdasarkan hasil penelitian dapat disimpulkan bahwa konsentrasi tertinggi material padatan tersuspensi berada di muara sungai dan daerah yang masih dipengaruhi oleh sungai dan mengecil menuju laut lepas.ABSTRACT: Kaliboyo River is an area that has potential by silting due to the deposition of suspended sediments. The potential of this silting can be known by understanding the value of concentration and the distribution of suspended sediment load. The high suspended sediment load concentration in the ocean is influenced by currents generated by tides.

The Cost

The so-called “Win-Continue, Lose-Reverse” (WCLR) rule is a simple iterative procedure that can be used to choose a value for any numeric variable (e.g., setting a price or a production level). The rule dictates that one should evaluate the effect on profits of the last adjustment made to the value (e.g., a price variation), and keep on changing the value in the same direction if the adjustment led to greater profits, or reverse the direction of change otherwise. Somewhat surprisingly, this simple rule has been shown to lead to collusive outcomes in Cournot oligopolies, even though its application requires no information about the other firms’ profits or choices. In this paper, we show that the convergence of the WCLR rule toward collusive outcomes can be very sensitive to small independent perturbations in the cost functions or in the income functions of the firms. These perturbations typically push the process toward the Nash equilibrium of the one-shot game. We also explore the behavior of WCLR against other strategies and demonstrate that WCLR is easily exploitable. We then conduct a similar analysis of the WCLR rule in a differentiated Bertrand model, where firms compete in prices.

Values has been explored in connection to a deeper understanding of human behavior. Values provide the answer to the basic existential questions, help to provide meaning in one’s life. Values are the key aspects of one’s self-esteem. They reflect diverse aspects of one’s social identity. According to a number of scientists, ethnic identity is a part of social identity. A number of studies in psychology has a focus on the connection between ethnicity and ethnic values. There are two main approaches towards the study of values can be distinguished. On the one hand, there are values that have the existential basis for the existence of people. On the other hand, the information about ethnic values can have applied aspect. The aim of this study is to identify differences in value orientation among representatives of two main linguistic groups that live in Eastern Latvia: the group of Latvian and Russian-speaking participants. The second goal is to explore the influence of religion, age and gender on the values of the research participants. The methodology used for the purpose of this study was to determine value orientation towards family, religious and friendship. The authors discovered statistically significant differences only in relation to a value of friendship. This value turned out to be the highest among the Russian-speaking group as compared to the Latvian-speaking group, as well as in the Orthodox group as compared to the group of Catholics.
