PENGARUH PENAMBAHAN NANO-TiO2 TERHADAP SIFAT MEKANIK DAN KARAKTERISIK MIKRO KOMPOSIT GEOPOLIMER SEBAGAI MATERIAL SELF-CLEANING

Penelitian ini berkenaan dengan pengembangan geopolimer berbasis metakaolin dengan agregat nano-TiO2 sebagai material self-cleaning. Penelitian ini bertujuan untuk mengetahui peran nano-TiO2, sifat mekanik dan karakteristik mikro dari komposit geopolimer sebagai material self-Cleaning. Komposit geopolimer disintesis menggunakan metode aktivasi alkali, dengan menggunakan metakaolin sebagai bahan dasar dan nano-TiO2 sebagai agregat. Variasi agregat nano-TiO2 didalam metakaolin yaitu mulai dari 0%, 0.25%, 0.50%, 0.75%, 1.00% relative terhadap massa metakaolin. Karakterisasi SEM-EDS digunakan untuk melihat morfologi dan mengetahui komposisi oksida unsur dari bahan dasar dan sampel. Karakterisasi XRD digunakan unutk melihat komposisi fasa dan struktur kristal sampel dan bahan dasar. Pengujian kuat tekan (compressive strength) dilakukan dengan menggunakan universal testing mechin. Hasil analisis sinar-X sampel menunjukkan adanya peningkatan fasa anatase seiring dengan penambahan nano-TiO2. Citra SEM memperlihatkan ikatan antara matriks dan agregat sudah terikat dan persebaran nano-TiO­2 dipermukaan matriks sudah merata. Nilai kuat tekan yang diperoleh sebesar 23.11 MPa dengan penambahan nano-TiO2 1 %. Pengujian self-cleaning dilakukan dengan memberi paparan sinar-UV pada sampel dan menunjukkan efek fotokatalis terbaik pada sampel dengan penambahan nano-TiO2 sebesar 1 %. Kata kunci : geopolimer, karakteristik mikro, nano-TiO2, self-cleaning, sifat mekani

Comparative Study of the Concept of the Welfare State According to Liberal, Islamic and the 1945 Constitution

This research aims to elaborate the thinking between the concept of the welfare state and the current understanding of democracy in Indonesia. the research used is normative legal research using a conceptual approach. The research results show that the concept of the welfare state emerged as an alternative to constitutional democracy in the 20th century, which was a reaction to the influence of liberal pluralism in the 19th century. This thinking gave rise to the proposition "the least government is the best government". The Welfare State is currently proven to be able to develop the economy while increasing the standard of living of the people. The current crisis of the welfare state, which is often debated, both in Europe and the United States, is not about its existence, but only about its size and capacity. The welfare state is nothing new in Islam. Before being implemented in the West, the Islamic world practiced it first

Hasil uji statistik pada 4 variabel menunjukkan 2 variabel yang berhubungan dengan penyalahgunaan narkoba yaitu teman sebaya/kelompok (p=0.000) dan kemudahan memperoleh narkoba (p=0,000) Sedangkan 2 variabel lainnya tidak berhubungan dengan penyalahgunaan narkoba yaitu riwayat pengguna dalam keluarga (p=0.212) dan keutuhan keluarga (p=0.955). Diharapkan kepada pemerintah daerah setempat untuk memperketat peraturan daerah mengenai penyalahgunaan narkoba dan disarankan agar pihak Polrestabes melakukan razia pada tempat yang dianggap rawan peredaran narkoba agar dapat mencegah maraknya kasus penyalahgunaan narkoba di Makassar, hal ini berkaitan dengan hasil penelitian yang menunjukkan adanya hubungan kemudahan memperoleh narkoba dengan penyalahgunaan narkoba di Kota Makassar

Air Defence Identification Zone (ADIZ) in International Law Perspective

Each country has full sovereignity over the airspace above its territory. In protecting its sovereignty and territorial integrity, the country will do several efforts. One of them is by deciding Air Defence Identification Zone (ADIZ). However, ADIZ has not any legal foundation that is explicitly stipulated in International law. Therefore it should value sovereignty of the other countries in order to maintain International peace and security Keywords : Sovereignty, ADIZ, International la

ECTOPARASITES FAUNA OF RODENTS AND SCANDENTS AT DIFFERENT HABITATS OF SARAWAK, MALAYSIA

Field surveys of ectoparasites fauna on small mammals (Rodentia and Scandentia) were conducted since 2008 until 2019 in 12 localities of Sarawak, Malaysia (Borneo). The objectives of these field surveys are to obtain checklist on the distribution of ectoparasites and their hosts (rodents and scandents) in Sarawak, and to determine the ectoparasites that are of known public health importance. Throughout these surveys, seven types of habitat had been recorded from 12 localities of study sites, namely lowland dipterocarp forest, mixed dipterocarp forest, hill dipterocarp forest, riverine forest, limestone forest, secondary forest, and urban area. A total of 50 to 100 cage traps were used to traps hosts for five to six consecutive days per site and ectoparasites were extracted from each host caught using fine comb and forceps. Identification of ectoparasites was based on morphology from available taxonomic keys and published taxonomic drawings. A total of 148 animals comprising 22 species of rodents and scadents were caught and screened for ectoparasites. Of these hosts, 46 species of ectoparasites were identified from a total of 2463 individuals collected. Among the ectoparasites found, six species collected are of known medical importance namely Ixodes granulatus (ticks) Laelaps nuttalli (mesostigmatid mites), Leptotrombidium deliense (trombiculid mites), Sarcoptes scabiei (astigmatid mites), Polypax spinulosa, and Hoplopleura dissicula (lice). Further surveys are recommended for more comprehensive inventory of ectoparasites in different locations and habitats that can build up extensive wealth of information on various aspects such as host-parasite relationship, biology and ecology

CHEMICAL AND ORGANOLEPTIC CHARACTERISTICS OF CHICKEN NUGGET BASED ON COMPOSITE FLOUR FROM MOCAF, BROWN RICE AND CORN STARCH

One of the foods favored by the public is nugget which is a fast food group with meat-based ingredients. In this study, mocaf, brown rice flour and corn starch were used as an alternative fillers to wheat flour as a means of reducing dependence on wheat flour as an imported product and increasing the nutritional content of nuggets. The purpose of this study was to determine the effect of variations in the formulation of ingredients on the organoleptic characteristics and chemical content of the nuggets that were most favored by the panelists. This research began with the nugget formulation, followed by organoleptic testing and chemical characterization of the nugget formula that was preferred by the panelists. The average results of the affection test showed that nugget B was preferred to nugget A, which used less, with the ingredient formula having a ratio of mocaf, brown rice flour and cornstarch, namely 4:1:3 (60g:15g:45g). The selected nugget formula contains water as much as 57.553%, fat content 1.055%, ash content 1.955%, protein 29.195%, crude fiber 16.064%, and carbohydrates other than fiber 10.205%. By not using wheat flour as the main ingredient, these nuggets can be regarded as an alternative food that is low in gluten and high in fiber because of the content in carrots, brown rice flour, and mocaf.</p
