Multi species model (anchovy, yellowstripe scad and narrow-barred Spanish mackerel) in Semarang coastal
Full text linkThe fishery sector in Semarang has been mostly dominated by artisanal fisheries with multigears
and multi-species. Although the fishery sector was not the major contributor to the GRDP of
Semarang city, the population of fishermen reached 1,068 whose welfare should be concerned. The
fishery sector helped the eradication of poverty and supported food security in Semarang city. Anchovy
(Stolephorus sp.), yellowstripe scad (Selaroides leptolepis) and narrow-barred Spanish mackerel
(Scomberomorus commerson) share an ecological relationship as predator and prey, which both have
been major marine commodities in Semarang city. Proper management should be applied to these
species in an integrated manner. This study developed and applied a multi-species (predator-prey) model
for anchovies, yellowstripe scad and narrow-barred Spanish mackerel. In this study, the production and
fishing activities were developed particularly for the three types of fish. The results indicated an
interrelated relationship between anchovy, yellowstripe scad and narrow-barred Spanish mackerel
productions. Optimal anchovy production (237,230 kg) was obtained when the fishing activities involved
779 fishermen. Whereas, the optimal yellowstripe scad production (6,873 kg) was obtained when 791
fishermen were involved, and the narrow-barred Spanish mackerel production was at the highest (159
kg) when 1,168 fishermen were involved
PROBABILISTIC ECONOMIC ORDER QUANTITY MODEL WITH PMETHOD, BACKORDER SYSTEM, AND QUANTITY DISCOUNT FOR MULTI-PRODUCT
Full text linkInventory problem is one of important things in an agency or individual engaged
in distribution. The problem in the real world is that the number of requests
randomly occurs, which causes difficulties in estimating inventory costs. This
thesis discusses that the inventory model for multi-product with the demand for
each type of goods is probabilistic, that occurs uncertainly and cannot be
determined beforehand and uses a backorder and discount system. The multiproduct inventory model is complete using the periodic ordering method. This
method aims to obtain the optimal ordering period and amount of inventory and
determine the minimum total inventory cost. Numerical simulations are provided
to illustrate the model. This inventory model is applied to Toko CK and the result
is that there is a total savings by 0,3% per month or 2,8% per year of inventory
costs.

Pemberian promosi jabatan merupakan bentuk penghargaan yang dapat diberikan perusahaan kepada karyawan. Hal ini juga dapat memberikan motivasi karyawan untuk meingkatkan kinerjanya. Permasalahan pemilihan karyawan yang memperoleh promosi jabatan termasuk kepada permasalahan pengambilan keputusan multikriteria. Metode yang sesuai diperlukan apabila kriteria yang digunakan sebagai evaluasi mengandung ketidakpastian. Pada tugas akhir ini dibahas kombinasi metode SAW (Simple Additive Weighting) dan relative preference relation. Metode SAW digunakan dalam proses normalisasi matriks keputusan sehingga membentuk matriks ternormalisasi. Teori relative preference relation digunakan untuk menghitung relative preference normalisasi matriks terhadap rata-rata normalisasi dan untuk menentukan peringkat alternatif. Studi kasus diterapkan pada sebuah perusahaan dengan menyeleksi tujuh karyawan yang akan mendapatkan promosi jabatan. Ketujuh karyawan tersebut dinotasikan sebagai A_1,〖 A〗_2,A_3,A_4,A_5,A_6 dan A_7. Kriteria yang digunakan untuk menyeleksi yaitu pendidikan terakhir, senioritas, pelatihan yang pernah diikuti dan aplikasinya, serta hasil penilaian kinerja.

REPRESENTASI PERLAWANAN WANITA DALAM FILM “MARLINA SI PEMBUNUH DALAM EMPAT BABAK”
Full text linkThis study aims to determine about how media industry describe the struggle of women facing the threat of crime from men out there by displaying their subjectivity through androgynous personalities. this topic is very interesting to study, because androgynous personalities quite helping to pushing women to become like a men who has strong figure, tough, independent, and brave figure against social injustice to carry out heinous activities to gain power of themselves. As presented by the movie “Marlina Si Pembunuh Dalam Empat Babak”. The movie conveys information to audiences about territory that still creates the existence of gender bias towards women. It is based on the reconstruction from the real reality in the Sumba territory, it can be seen how women fight the system that exists in the midst of patriarchal tradition. This study using standpoint theory, liberal feminism, and three other concepts such as representation, women resistance, and female masculinity that leads to masculinity. This study uses a qualitative approach focusing on interpretive descriptive which is critical in Roland Barthes’ semiotic analysis method through lexia analysis and five existing reader codes which is hermeneutic code, pro-aretics code, symbolic code, cultural code, and semik code. The data of the research is collected through observing a scene that will be used as a source of object and conclusions that will be analyzed about Representation of Women Resistance in movie “Marlina Si Pembunuh Dalam Empat Babak” by taking documentation results from a few scenes which will be screenshot.
The result of discussion carried out in this study shows the empowerment of women in carrying out their subjective actions against the patriarchal system that makes them gender biased. Because the media show the audiences that they often get repercussions from the patriarchal system that has shaped people’s view into deviant ideologies from various stereotypes of women. The stereotype considers women as people who are used to taking care of household domestic affairs as the Javanese proverb says: masak, macak, manak. This is a form of violence against women that often afflicts various oppressions that occur anywhere and anytime. The social system treats women unfairly because they have arbitrarily influenced them. This leads to the cultural element of feminism that will never stop instilling the ideology of the media to opress minorities. So that the audience will form the meaning of what the mass media displays for blaming the victims. Basically women are always used as a victims of sexual harassment or abuse because they deserve to be treated harshly by men. Besides that, showing movies in Indonesia also spreads elements of social construction unfairly which have created social inequality to bring down women and prioritize men as a domination of all aspects of life socially, legally, and politically. However, this makes them dare to come out of their roots of oppression by displaying an androgynous personalities as having a strong, tough, and independent figure. This is for the sake of continuity in the next life in order to have social welfare freely without any worries about the threat of men out there. Therefore, the media can represent when spreading ideology with positive things to be a material for improving the audiences’ point of view when looking at the depiction of gender. That way the audiences can receive information critically in shaping the meaning of the message that does not just take it for granted, but still has awareness when consuming what is displayed by media content. So that the audience does not fall into a deviant ideology
