Tujuan penelitian ini adalah untuk mengetahui pengaruh kadar air pada pada proses pemucatan minyak kelapa sawit terhadap warna minyak dan terhadap asam lemak bebas. Penelitian dilakukan pada temperature operasi 70 °C dengan menggunakan pompa vakum (30-40 cmHg). Bahan pemucat yang digunakan tanah bentonite sebanyak 1,5% dari berat total keseluruhan minyak. Dilakukan dengan bantuan pengaduk dalam membantu penyerapan zat warna selama 30 menit oleh tanah bentonite. Hasil penelitian menunjukkan bahwa Kandungan air dalam minyak sangat berpengaruh terhadap warna minyak yang dihasilkan pada proses pemucatan. Bertambahnya kadar air, maka sangat berpengaruh terhadap warna minyak . Pengaruh kadar air juga terlihat terhadap asam lemak bebas (bilangan asam). Semakin tinggi kadar air minyak maka semakin besar harga bilangan asam minyak .

 

Water naturally exists in oil. In the neutralization stage for refining palm oil, water is also formed due to the reaction between caustic soda and free fatty acids. The purpose of this study was to determine the effect of water content on the bleaching process of palm oil on the color of oil and on free fatty acids. This study was carried out at an operating temperature of 70°C using a vacuum pump (30 - 40 cmHg). The bleaching material used by bentonite soil was 1.5% of the total weight of the oil. It was carried out with the help of a stirrer to help the dye absorption for 30 minutes by bentonite soil. The results showed that the water content in the oil greatly affected the color of the oil produced in the bleaching process. The increase of the water content greatly affected the oil color. The effect of water content was also seen on free fatty acids (acid numbers). The higher the water content of the oil, the greater the number of oil acid.

Does the Arab spring wave
affect outward foreign direct investment (FDI)? Empirical evidence from the
Mideast and North Africa
Authors: Hraiba Aymen , Ganić Mehmed , Branković Azra
Published: May 2019

The paper aims to empirically
explore the impact of the Arabic Spring on the outflow of FDI in twelve
selected countries in the North Africa region (Algeria, Tunisia, Morocco,
Libya, Egypt and Mauritania) and the Mideast region (Bahrain, Kuwait, Oman,
Lebanon, Jordan and the United Arab Emirates). The paper employs a panel data
approach to exploit the time series nature of the relationship between FDI Outwards
and its determinants (the market size, trade openness, government
effectiveness, inflation and three dummy variables related to the Arab Spring)
between 2000 and 2016. The findings revealed that the impact of the Arab Spring
estimator is negatively correlated with FDI Outflows in the countries that witnessed the Arab
Spring. It implies that conflicts and instability negatively affect FDI
outflows. The findings of this study reveal that countries that have been
affected by the Arab Spring directly (the North Africa region) experienced a
greater decline of FDI outflows than countries that have been indirectly affected (the Mideast region). When
the sample is restricted to North Africa it is shown that the FDI outflows may
be influenced by the post Arab Spring effect, while there is no such statistically
significant effect in the Mideast
region. Thus, the study finds that FDI outflows in the North African countries are more determined by the effects of
Arabic Spring countries than in the Mideastern countries.
Istraživanje preferencija
potrošača pri odabiru trgovačkih lanaca
Authors: Soče Kraljević Sandra , Božić Kristian
Published: May 2019

U Europskoj uniji tržištem hranom
dominiraju veliki trgovački lanci, a posljednjih nekoliko godina taj trend primjetan
je i u Bosni i Hercegovini. Iako su zakoni o zabrani monopola na snazi, još
uvijek nema mehanizama koji mogu kontrolirati moć velikih trgovačkih lanaca.
Prema istraživanju britanske Komisije za konkurenciju, svaki trgovački lanac
koji ima više od osam posto udjela na tržištu hranom ima i dovoljno moći da
negativno utječe na konkurentnost na tržištu te samim time i na plasman
hrane.Kupovne navike potrošača jedan su od ključnih čimbenika koji utječu na
sliku maloprodajnog tržišta kako na lokalnom tako i na globalnom nivou. Iako su
suvremeni potrošači suvereni, itekako se može na njih marketinški utjecati.
Marketari mogu utjecati na njihovo ponašanje tako što će elemente marketinškog spleta
prilagoditi potrošačevim potrebama. Uspjeh se postiže ako potrebe postoje ili
su latentne i proizvođač ih potakne proizvodom koji potrošači svjesno ili
podsvjesno trebaju. Ponašanje potrošača je pod utjecajem brojnih čimbenika koji
su međusobno povezani, a mogu se svrstati u tri skupine: osobni čimbenici,
društveni čimbenici i psihološki čimbenici. Stoga, glavni cilj ovog rada je
ispitati preferencije potrošača u odabiru trgovačkih lanaca na području grada
Mostara. Kroz anketiranje koje će biti provedeno s potrošačima
na području grada Mostara, uz njihove preferencije u odabiru trgovačkih lanaca,
ispitat će se i glavne odrednice koje utječu na potrošačev odabir.Ovim radom je
prezentirano primarno istraživanje koje upućuje da se razlikuju preferencije
potrošača kad abiraju trgovački centar te da najrađe posjećuju najbliži
trgovački centar. Značaj ili znanstveni doprinos ovog istraživanja je dvojak,
ovaj rad može koristiti marketarima i menadžerima u poduzećima i trgovačkim
centrima koji posluju na tržištima gdje je sve veća konkurencija kako bi svoje
potrošače potakli da više kupuju te time povećali prodaju i konkurentnost što
je podjednako važno i za znanstvenike (istraživanje tržišta, prodaja, ponašanje
potrošača) s aspekta boljeg razumijevanja preferencija i čimbenika koji utječu
na izbor trgovačkog lanca. Na kraju rada navode se ograničenja istraživanja kao
i smjernice za buduća istraživanja.

6-day-old term infant with fever and lethargy
Authors: Akangire Gangaram
Published: May 2019

Osteomyelitis in the neonatal period can be a diagnostic challenge, especially if it is mimicking brachial plexus palsy. We present a unique case of 6-day-old term infant with lethargy and fever diagnosed with Group B Streptococci (GBS) sepsis and meningitis. Few days later, infant developed right arm immobility leading to hematogenous spread of GBS to right humerus, leading to osteomyelitis and septic arthritis. Infant was treated with intravenous Ampicillin for 4 weeks with full arm mobility and full recovery from sepsis and meningitis.

Epithelial ovarian cancer: Evolution of management in the era of precision medicine
Authors: Lheureux Stephanie , Braunstein Marsela , Oza Amit M.
Published: May 2019

Ovarian cancer is the second most common cause of gynecologic cancer death in women around the world. The outcomes are complicated, because the disease is often diagnosed late and composed of several subtypes with distinct biological and molecular properties (even within the same histological subtype), and there is inconsistency in availability of and access to treatment. Upfront treatment largely relies on debulking surgery to no residual disease and platinum‐based chemotherapy, with the addition of antiangiogenic agents in patients who have suboptimally debulked and stage IV disease. Major improvement in maintenance therapy has been seen by incorporating inhibitors against poly (ADP‐ribose) polymerase (PARP) molecules involved in the DNA damage‐repair process, which have been approved in a recurrent setting and recently in a first‐line setting among women with BRCA1/BRCA2 mutations. In recognizing the challenges facing the treatment of ovarian cancer, current investigations are enlaced with deep molecular and cellular profiling. To improve survival in this aggressive disease, access to appropriate evidence‐based care is requisite. In concert, realizing individualized precision medicine will require prioritizing clinical trials of innovative treatments and refining predictive biomarkers that will enable selection of patients who would benefit from chemotherapy, targeted agents, or immunotherapy. Together, a coordinated and structured approach will accelerate significant clinical and academic advancements in ovarian cancer and meaningfully change the paradigm of care.

Moral Rebellion and Religiusity in Pious Muslim Novels: Chavchay Saifullah and Muhidin M Dahlan Review of Sociology of Literature
Authors: Sahrasad Herdi , Ridwan Muhammad
Published: May 2019

This article argues that novelists Muhidin M Dahlan and Chapchay Syaifullah tried to make moral and religious rebellions in their work as a result of existing social conditions. They rebel against normative and established values, old order and social arrangements. They are creative in the context of literature as a fictional world built with the spirit of renewal and enlightenment. And here, imagination is a significant creative process for deconstruction and enlightenment as well as upheaval in religiosity, religious rebelion, religious dissent.In this context, Muhidin and Syaifullah novels do not place religious life as a problem solver. Borrowing Goenawan Mohamad's definition that works that can be categorized as "religious literature" are works that "place religious life as a solution to problems", it appears that Muhidin and Syaifullah's novels cannot be called "religious literature" in the conventional sense. In this case, as a religiosity rebellion - where religiosity is defined as a philosophy of life or awareness of 'His breath' in everyday life, that is an awareness that is entirely personal and because it is personal, everyone has the right to sue, question, reject or deconstruct his own religious teachings.
