Abstract

Brick is a building material that is often used for residential walls. The bricks in this study were bricks with the addition of palm frond charcoal in the manufacturing process. The aims of this study were (1) to determine the effect of adding palm stem charcoal on the manufacture of red bricks in terms of compressive strength, water absorption (Suction rate) and apparent density (apparent density). (2) Comparing the test results with the SNI 15-2094-2000 standard. The manufacture of experimental bricks begins with adding clay with pulverized palm frond charcoal in a ratio of 100:0, 95:5, 90:10, 85:15 and 80:20, then molded, dried, burned and tested for new mechanical properties. brick. In this study, the compressive strength of bricks that enter class 100 is a ratio of 100:0 and 95:5 namely 11.75 Mpa and 10.10 Mpa, then bricks grade 50 is a ratio of 90:10 and 85:15 which is 8.08 Mpa and 6.27 Mpa. The water absorption capacity of bricks that meet the requirements of SNI 15-2094-2000 is a ratio of 100:0 and 95:5, namely 18.65% and 19.74%. The apparent density of bricks that meet the requirements of SNI 15-2094-2000 are the ratios of 100:0, 95:5, 90:10 and 85:15, which are 1.63 g/cm3, 1.54 g/cm3, 1,37 g/cm3 and 1.24 g/cm3. Bricks that meet the standards and are recommended as masonry bricks are bricks with a ratio of 95:5.

Abstract

Pandemi COVID-19 menyisakan ketidakstabilan ekonomi pada masyarakat. Harga bahan kebutuhan pokok yang masih tinggi, membuat para ibu rumah tangga harus berpikir keras untuk mengelola keuangan keluarga. Hal ini dialami oleh beberapa ibu rumah tangga di lingkungan Perumahan Mutiara Ayu 8 Desa Kualu Kecamatan Tambang Kabupaten Kampar. Kegiatan ini dilakukan untuk meningkatkan pengetahuan para ibu rumah tangga dalam manajemen keuangan keluarga dan memberikan motivasi bisnis untuk menambah pendapatan keluarga. Metode yang dilakukan adalah observasi lapangan, melaksanakan penyuluhan tentang manajemen keuangan dan motivasi bisnis, dan evaluasi hasil kegiatan terhadap 20 orang ibu rumah tangga. Manajemen keuangan keluarga yang efektif dapat dilakukan dengan cara membedakan kebutuhan dengan keinginan, menyusun daftar pengeluaran prioritas per bulan, alokasikan dana untuk tabungan dan dana darurat, dan minimalisir hutang. Untuk menambah pendapatan keluarga, ibu rumah tangga dapat melakukan bisnis sendiri. Hal-hal yang perlu dipersiapkan untuk memulai bisnis adalah adanya dukungan keluarga, sesuaikan dengan kemampuan, dapat memisahkan antara keluarga dan bisnis, menyusun target, dan perluas jaringan. Hasil kegiatan ini menunjukkan adanya peningkatan pengetahuan tentang manajemen keuangan dan bisnis pada para peserta.

Abstract

Bioplastics are destructive plastics that break down by the environment, humidity, and microorganism activity. Bioplastics can be used just like conventional plaques. Bioplastics include natural polymers made from plant and animal materials. Tapioca flour is pure starch obtained from the extraction of cassava milling and continues to amylose and amylopectin. Maize flour is flour obtained by grinding clean and good corn kernels through the process of obtaining skin, endosperms, institutions, and the tip of the hat. This research helps make bioplastics using tapioca flour as an adhesive and cornstarch as an efficient thickener. The use of tapioca flour and cornstarch in producing bioplastics was using the blending method. Variations in the amount of acetic acid were 2 ml, 4 ml, and 6 ml, the amount of glycerin was 2 ml, 4 ml, and 6 ml, and tapioca flour and cornstarch were 6 gr at 700oC. Bioplastics are made by mixing 6 gr tapioca flour and 6 gr cornstarch, 50 ml distilled water, and heated to a temperature of 700oC. Bioplastic test results announced by the fourth bioplastic (2.649 MPa), the best thickness possessed by the ninth bioplastic (0.12 mm), the best resistance needed by the eighth bioplastic (46.15%), and the fastest or best degradation time by bioplastics three and ninth (6 days). The effect of using glycerin is very dominant in the test results but not for the use of acetic acid.
