Abstract

Bali cattle constitute one of Indonesia's native germplasm sources for meat supply. Beef is one of the primary sources of protein that plays a crucial role in meeting the nutritional needs of the community. The research material consisted of 251 female Bali cattle aged 12 months and 24 months. These Bali cattle belong to the farmer group in Bontang city, Kutai Timur Regency (Kutim), Berau Regency, Kutai Kartanegara Regency (Kukar), Penajam Paser Utara Regency (PPU), and Paser Regency. The morphometric traits measured were withers height (WH), chest girth (CG), and body length (BL). The data obtained were analysed via analyses of variance, and if there were significant differences, the analysis was continued until a least significant difference was detected. The results revealed significant differences in the morphometric characteristics of 12-month-old Bali cattle across regions (P<0.01). The highest WH was from Bontang cattle (104.30±3.16a), and the lowest was from PPU (98.94±6.79c). The CG of Bontang cattle also had the highest value (131.30±6.29a), and the lowest value was from PPU (119.59±7.34b), with the highest BL of cattle from Berau (101.22±2.73a) and the lowest value from PPU (93.35±4.89b). Twenty-four-month-old female Bali cattle also presented significant morphometric differences (P<0.01) across regions. Cattle from the PPU consistently excelled in all parameters: WH (108.00±2.24a), CG (138.40±3.51), and BL (110.60±6.66a). The lowest WH was cattle from Berau at WH (101.33±0.58b), CG (126.00±2.65), and BL (97.33±4.62b). In conclusion, on the basis of observations of withers height, heart girth, and body length, all individual samples met the Indonesian National Standard (SNI) criteria for female Bali cattle breeding stock. Significant morphometric differences are caused by local genetic selection factors, the environment, feed availability, feed quality, and management practices.

Abstract

Abstrak Plastik merupakan sampah anorganik yang sulit terurai dan akan terurai dalam kurun waktu puluhan atau ratusan tahun kemudian. Paving block merupakan salah satu bahan bangunan dengan komposisi campuran dari semen portland atau perekat hidrolis lainnya, air dan agregat dengan atau tanpa bahan tambahan lainnya yang tidak mengurangi mutu dari beton tersebut (SNI, 1996). Penelitian ini bertujuan untuk mengetahui sifat mekanik paving block dengan campuran tanah lempung dan limbah plastik dan pengaruh dari jenis plastik yang digunakan terhadap mutu paving block yang dihasilkan. Hasil penelitian menunjukkan bahwa nilai kuat tekan tertinggi paving block campuran tanah lempung dan plastik LDPE dengan perbandingan 75% : 25% yaitu 9,59 MPa kuat tekan tertinggi pada campuran tanah lempung dan plastik PP dengan perbandingan 100% : 0% yaitu 9,18 MPa. Jenis plastik yang dipergunakan mempengaruhi mutu paving block. Paving block pada penelitian ini termasuk dalam mutu D dapat   digunakan pada konstruksi taman berdasarkan SNI 03-0691-1996. Kata kunci: Plastik, tanah lempung, paving block   Abstract Plastik is inorganic waste that is difficult to decompose and will decompose within tens or hundreds of years later. Paving block is a building material with a mixed composition of portland cement or other hydraulic adhesives, water and aggregates with or without other additives that do not reduce the quality of the concrete. This study aims to determine the mechanical properties of paving blocks with a mixture of clay and plastik waste and the effect of the type of plastik used on the quality of the paving blocks produced. The results showed that the highest compressive strength value of paving blocks mixed with clay and LDPE plastik with a ratio of 75%: 25%, namely 9.59 MPa, the highest compressive strength was in a mixture of clay and PP plastik with a ratio of 100%: 0%, namely 9.18 MPa. . The type of plastik used affects the quality of paving blocks. Paving blocks in this study are classified as D quality and can be used in garden construction based on SNI 03-0691-1996 Keywords: Plastik, clay, paving block
