Studi Kelayakan Penggunaan Cangkang Kemiri Sebagai Pengganti Sebagian Agregat Kasar Terhadap Mutu Beton

In the current era of globalization, the development of concrete in the construction sector is very rapid, be it housing, offices, bridges, roads, dams, ports, and others. That is inseparable from the use of concrete as a part of building construction. The use of coarse aggregate for concrete mixes, namely natural stone, is a non-renewable natural resource. Therefore an alternative is needed as a substitute. One of the natural resources that can be renewed is hazelnut skin. Candlenut is a traditional plant that has various benefits, one of which is a candlenut shell. In this study, the materials used for standard concrete mixtures consist of water, cement, fine aggregate, and coarse aggregate. The water used for mixing the concrete is taken from the PDAM channel. The results showed that the effect of candlenut shells used as a substitute for some coarse aggregate decreased compressive strength results from the results of standard concrete compressive strength. The results obtained by the value of standard concrete compressive strength at 28 days of concrete were 27.19Mpa for concrete using Candlenut shells of 20% produce a compressive strength value of 17.33 Mpa at 28 days of concrete. 35% produce a concrete compressive strength value of 16.04 Mpa, while 50% produce a concrete compressive strength value of 15.17 Mpa. Thus the research shows that more and more candlenut shells are being used as a substitute for coarse aggregate in the concrete mixture

Peranan Pramuka Gugus Depan Sultan Sulaiman-aminah Syukur Dalam Pembentukan Karakter Mahasiswa Di Iain Samarinda

Pramuka is an Indonesi word that stands for Praja Muda Karana that means productive youths. The process of character building in Pramus is began from elementary school level up to higher education level. This research, therefore, aims at answering the question of how the process of character building of undergraduate students is applied in the Pramuka as a college estra-currucular activity of IAIN Samarinda. Thus, participant observation, deep interview, and documentation techniques are utilized to gain empirical as well as qualitative data to support the process of data analysys in this research. Findings suggest that in the pramuka of Sultan Sulaiman-Aminah Syukur, the principe of dasa darma – ten services – is implemented to help its student members to build good character and personality

Distance Learning System Based On Web English Course Using Php And Mysql

Melihat konsep pembelajaran tradisional yang dilakukan saat ini, para siswa danguru bertemu pada suatu tempat dan waktu tertentu. Sistem pembelajarantradisional ini akan tergantikan dengan sistem pembelajaran jarak jauh yanglebih praktis dan tidak terpengaruh ruang dan waktu, sehingga memberikanmanfaat untuk berbagai kalangan dari pemilik tempat kursus tidak perlumembangun infrastruktur sampai pada manfaat yang dirasakan masyarakat yaitumendapat kesempatan belajar lebih lama, yang tersajikan di dalam websitedengan bahasan meliputi membaca, menulis, percakapan. Di dalampembelajaran jarak jauh fokus utamanya adalah pelajar. Pelajar bersikap mandiridan bertanggung-jawab untuk pembelajarannya. Suasana pembelajaran jarakjauh akan memaksa pelajar memainkan peranan yang lebih aktif dalampembelajarannya. Membiasakan diri terhadap bahasa Inggris sejak usia SDmerupakan salah satu cara terbaik agar anak-anak dapat fasih berbahasa Inggrisdi kemudian hari. Hasil dari sistem pembelajaran jarak jauh berbasis web padakursus Bahasa Inggris dengan bahasa pemprograman php dan mysql untukpemprograman databasenya, ditampilkan dalam bentuk website yang didalamnya ada tomboltombol yang memudahkan siswa untuk belajar tanpa harusdidampingi oleh pengajar. Tombol-tombol tersebut adalah home, kategori,kurikulum, pengajar. Pembelajaran jarak jauh memberikan alternatif pemerataanpendidikan dan memberikan solusi masalah yang terdapat dalam konseppendidikan tradisonal salah satunya adalah letak geografis

Alternatif Angkak Sebagai Bahan Tambahan Pangan Alami Terhadap Karakteristik Sosis Daging Ayam

Penelitian ini dilakukan untuk mengetahui pengaruh pemberian angkak sebagai bahan tambahan pangan alami serta untuk mengetahui level yang optimal terhadap karakteristik sosis daging ayam. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 5 perlakuan dan 5 kelompok sebagai ulangan. Perlakuan : P-Sp (sosis daging sapi) dan sosis daging ayam dengan berbagai level angkak (0 %, 0.5 % ; 1.0 % dan 1.5 %).Peubah yang diamati meliputi nilai pH (daging dan adonan), rendemen, susut masak, kadar protein, lemak, air dan kolesterol serta sifat organoleptik. Hasil penelitian menunjukkan bahwa sosis dengan pemberian angkak memberi pengaruh yang nyata (P < 0.05) terhadap rendemen, susuk masak dan atribut warna. Akan tetapi tidak menunjukkan adanya pengaruh (P > 0.05) terhadap nilai pH adonan sosis, nilai gizi (protein, lemak, air dan kolesterol) serta atribut tekstur, bau, rasa dan kekenyalan sosis. Semakin meningkat level angkak, rendemen dan atribut warna semakin meningkat, sebaliknya karakteristik susut masak semakin menurun. Berdasarkan hasil penelitian dapat disimpulkan, sosis ayam dengan pemberian angkak lebih disukai dibanding sosis daging sapi. Level angkak 1 % (P-1.0) memberi karakteristik sosis yang paling baik dibanding dengan perlakuan atau level yang lain

Optimasi Sabun Cair Antibakteri Ekstrak Etanol Rimpang Jahe Merah (Zingiber Officinale Rosc. Var. Rubrum) Variasi Virgin Coconut Oil (Vco) Dan Kalium Hidroksida (Koh) Menggunakan Simplex Lattice Design

Antibacterial liquid soap help prevent the infection of pathogenic bacteria, such as S. aureusand E. coli that can cause skin infection and diarrhea. Red ginger is one of natural plants that hasthe potential as an antibacterial agent in soaps and also known to have antibacterial activity. Soap isformed from the reaction between a fattty acid and base so its quality is affected by the perfection ofthat reaction. The purpose of this study was to determine the optimum composition of VCO andKOH using Simplex Lattice Design (SLD) and its physicochemical properties. The extraction wasdone by soxletation method using ethanol 96%. Antibacterial test showed that the optimumconcentration of the extract was 50 mg/mL. Soap with variation of the VCO and KOH had specificgravity 0,955-1,045; viscosity 0,3-2,1; pH 9,366-10,566; and free alkali 7,48x10%.The composition of the VCO and KOH that predicted by SLD is 26,386 g VCO and 6,414 g KOH.This optimum formula had specific gravity 1.03148; viscosity 0.723; pH 10,066; and 0.0086% freealkali. Independent two-sample test between the physicochemical properties resulted from the testand results predicted by SLD showed no significant difference (p>0,05). The antibacterial activityof optimum formula didn't differ significantly with the control (p>0,05)
