Published: January 2019

Nickel catalyst has been prepared impregnation and precipitation with nickel content of 20% and 25% each using bentonite as support material. The effects of the preparation method were studied using temperature programmed oxidation (TPO) and temperature programmed reduction (TPR) and by determination of its specific surface area. The activity of catalysts has been tested in the hydrogenation of palm oil. The catalyst with 20% of nickel and prepared by impregnation shows a single peak at 301°C, compared to catalyst with 25% of nickel prepared by the same method which has a peak at 304°C and a shoulder at 330°C. The reduction curves of both catalysts, those are prepared by impregnation, show a homogeneity indicated by a high main peak at 426°C (20% Ni) and 430°C (25% Ni). The 25% nickel catalyst by impregnation has a shoulder at 508°C. The catalysts prepared by precipitation show peaks at 508°C and 661°C for 20% of Ni and peaks at 419°C and 511°C for 25% of Ni. The reduction curves of catalysts prepared by precipitation are significantly different from each other. Those are also very different comparing to the reduction curve of impregnated catalyst. The 20% precipitated nickel catalyst has a single peak at 540°C, but the 25% precipitated nickel catalyst shows peaks at 346°C and 503°C. The differences of peak position among the reduction curves of catalysts resulted in the differences of catalyst activities with the following order 20% Ni (impregnation) > 25% Ni (impregnation) > 20% Ni (precipitation) > 25% Ni (precipitation).

Authors: Astuti Endang , Haryadi Winarto , Matsjeh Sabirin 
Published: January 2019

Palm oil contains unsaturated fatty acids that can be oxidated and can make rancidity of the palm oil. One of the trigliserida degradation products is free fatty acid. The usage of triethylammine (TEA) in the polar-nonpolar mix solvents could enhance the free fatty acids extraction efficiency. Free fatty acids extraction from palm oil was carried out for a minute with solvents ratio: TEA 0,00-0,20M in the following solvent: 0-99% diethyl ether + 99-0% ethanol + 1% water, % volume. The extraction was also performed in the following solvent: TEA 0,00-0,20M in 0-95% heptane + 95-0% isopropanol + 5% water, % volume. Reextraction was conducted for a minute by adding Na2SO4 1M. The alcohol layer which was rich with free fatty acid was taken out and the acid value was determined. As comparison, palm oil's free fatty acids was taken out with standard method by refluxing the sample in 95% alcohol for ten minutes. Identification of the free fatty acids was done by Gas Chromatography-Mass Spectrometer. The best solvent ratio for acid value determination was TEA 0,10-0,20M in the mix-solvent: 19% diethyl ether + 80% ethanol + 1% water, % volume and the extraction product contained 8 kind of free fatty acids. In addition, TEA 0,01M in the solvent: 95% isopropanol + 5% water, % volume could be obtained 8 kind of free fatty acids too. In contrary, the free fatty acid extraction by standard method contained 7 kind of fatty acids. Linoleic acid was the free fatty acid which could not be taken out by standard method. The usage of TEA in the proper polar-non polar mix-solvent was the complete method to determine free fatty acid contained in the palm oil. Keywords: triethylammine, free fatty acid, organic extraction.

Modeling of several alkyl salicylates based on electronic transition by using semiempriical mechanical quantum ZINDO/s calculation has been done. Object of these research were assumed only alkyl salicylates of C4 (butyl) until C8 (octyl) homologue with 4-7 example structures of each homologue. All of the computation have been performed using quantum chemistry - package software Hyperchem 6.0. The research covered about drawing each of the structure, geometry optimization using semiempirical AM1 algorithm and followed with single point calculation using semiempirical ZINDO/s technique. ZINDO/s calculations used a defined criteria that is singly excited - Configuration Interaction (CI), gap of HOMO-LUMO energy transition was 2 and degeneracy level was 3. Analysis of the theoretical spectra was focused in the UV-B (290-320 nm) and UV-C (200-290 nm) area. The result showed that modeling of the compound can be used for predicting the type of UV protection activity depending with the electronic transition in the UV area. Modification of the alkyl homologue relatively did not change the value of wavelength absorbtion to indicate the UV protection activity. Alkyl salicylate compounds were predicted as UV-C sunscreen or relatively the compounds have protection effect for UV-C. Keywords: alkyl salicylate, sunscreen, semiempirical methods
FARMING SYSTEM AND DEMOGRAPHIC BREAK POINTS
Authors: Benoit Daniel 
Published: January 2019

Propinsi Lampung sampai pertengahan tahun 1970-an masih daerah penerima. Sejak lima belas tahun beberapa bagian propinsi ini menjadi daerah pengirim. Untuk menguraikan kejadian itu, suatu angka "tekanan penduduk" dipakai. Angka tekanan penduduk dihitung dari kepadatan penduduk dan penggunaan tanah. Kalau "tekanan penduduk" mencapai suatu tingkat yang tinggi (demographic break point) untuk kepala keluarga ada dua kemungkinan - mengganti cara pengolahan/penggunaan tanah, atau pindah. Untuk peilihan penggunaan tanahh tersebut faktor budaya (suku bangsa) lebih berpengaruh daripada kesuburan tanah. Untuk sistem perkebunan tingkat tekanan penduduk adalah 300j./km2, untuk persawahan: 600s.d. 1.000/km2, dan untuk tegalan: 300 s.d. 350j./km2.

Permukiman di sepanjang daerah aliran sungai (DAS) merupakan masalah yang tidak bisa dihindarkan di kota-kota besar di Indonesia. Kota Yogyakarta dialiri tiga sungai yang kiri-kanannya terdapat hunian yang padat. Selain padat, kualitas permukiman juga buruk. Pihak penguasa tidak lagi berusaha untuk menghilangkan permukiman itu karena dianggap tidak akan memecahkan masalah. Sebaliknya, telahdiimplementasikan kebijakan yang tujuannya untuk memperbaiki kualitas permukiman tersebut, baik dari sisi fisik maupun nonfisik. Tidak kurang dari tujuh program telah dilaksanakan di sepanjang aliran sungai di Yogyakarta. Sayangnya, sebagian besar program tersebut belum bisa dikatakan sukses. Sifat program yang sporadis atau tidak berkesinambungan, kurang terlibatnya pemimpin informal setempat, dan lemahnya upaya menggalang partisipasi masyarakat adalah sebagian penyebab kurang berhasilnya program-program yang dilaksanakan.

Published: January 2019

Up to now the residual product from the social construction of sexuality and gender is still considered as a reference by most of the society so that they put women in the subordinate position. In the sexuality sphere, the women's powerlessness is obviously seen as reflected in the constraint of sexual intercourse, violation, wives who take high risk of HIV/AIDS,and so on. Yulfita Raharjo reveals several sexuality lamenesses and gender problems. This writing,further, describes the solution of the problems through a deconstruction and reorientation in understanding the gender relationship, i.e. the partnership relation between men and women.

Family planning is an instrument to achieve family welfare but it is not the only one. However, the simplification of family planning-family welfare linkage has exagerated the family planning role. Many studies, such as conducted by Population Studies Center Gadjah Mada University, show that the direct effects of family planning practice and fertility on family welfare are weak. Understandingthat the role is not big as expected, BKKBN introduced family welfare program. The program seems meaningful but institutionally it looks inappropriate. We suggest BKKBN to concentrate on its core bussines,e.g. serving FP,rather to do the family welfare program.

Akhir-akhir ini, keterlibatan pria dalam kesehatan reproduksi secara umum mulai banyak mendapat sorotan. Tulisan ini terutama membahas apakah keterlibatan tersebut berartimempersempit kesenjangan antara pria dan wanita secara umum. Dengan perspektif gender, keterlibatan pria dan wanita dianalisis dalam 3 tingkatan, yaitu pada tingkat kebijakan internasional, tingkat program dan tingkat individu. Hasil studi pustaka ini menunjukkan bahwa proses pembuatan keputusan yang berkaitan dengan keluarga berencana belum banyak dibahas, berbeda halnya dengan jenis keputusan dan pembuat keputusan. Untuk menyatakan bahwa keterlibatan pria berakibat positif terhadap kesetaraan gender (gender equality), diperlukan pemahaman yang lebih mendalam mengenai proses pembuatan keputusan sebagai titik kritis ke arah kesetaraan jender.

Although the population registration in Indonesia has long been put through, the result is still unreliable, thus population census should be considered as a major source in providing data of population and households. Since its independent status, Indonesia has carried out the census for five times: in 1961, 1971, 1980, 1990, and in 2000 with the goals of providing a considerable amount of details of population data such as: buildings and households, villages potential (potensi desa or podes), and main pattern frames for survey and others census applications.The collected data contain information of households and individuals by the census taking system both de jure and de facto for the entire population of Indonesia, including those living abroads such as diplomatic corps with their family members. For the 2000 population census of Indonesia or SP 2000, the data of household and population by temporary residence status, have been put through by the national Central Bureau of Statistic, whereas the data of those by permanent residence status have been carried out by the Regional Central Bureau of Statistic, which are all predicted would be finished before the end of the year of 2000.

POR QUE NÃO TE CALAS? POLÍTICAS NA ESCOLA

Published: January 2019

Pensar e falar como ações de riscos: políticas, sociedades e escolas “Por que não te calas?” é uma expressão que todas e todos nós identificamos, como advinda da “ XVII ‘Cumbre’ Ibero-americana”, realizada em Santiago, em outubro de 2007, tendo sido pronunciada pelo Rei da Espanha, inter- rompendo o Presidente da Venezuela.Ainda que a conduta política de Hugo Chavez comporte justificáveis controvérsias, essas palavras do Rei Juan Carlos ressoaram como um signo da prepotência, como se o emitente se julgasse com o direito de repreender e censurar, provavelmente, pelos incômodos que incluem a não-admissão de paridade com uma ex-colônia, sobretudo quando a fala de um de seus presidentes interroga “os grandes” sobre as intromissões concretas em várias repúblicas, também constituintes da Ibero-América.
