Abstract

The aim of study to test the inhibitory solution of lidah merua (Sansevieria trifasciata) on amount of bacteri, protein content, and organoleptic characteristics (color, aroma, and, mucus) of broiler chickens meat (Gallus domesticus). Study was conducted in a completely randomized experimental design with 5 level solution of S. Trifasciata (0, 15, 30, 45, and 60 g/100 ml), each of treatment was 4 replication. Application have done by soaking 100 g broiler chickens meat in solution of S. Trifasciata for 30 minutes. The result of this study shown soaking broiler chickens meat in solution of S. Trifasciata significant (P<0,05) influence amount of bacteri, but not significant (P> 0.05) influence protein content, and organoleptic characteristics (color, aroma, and mucus). solution of S. Trifasciata concentrations 15 g/100 ml can be durable chicken brioler meat and not change protein content. But organoleptic characteristics color and aroma of broiler chickens meat which like panelists are the concentration 15 g/100 ml and mucus of broiler chickens meat which like panelists are the concentration 45 g/100 ml. Study conclude that soaking broiler chickens meat in solution of S. Trifasciata can be hamper amount of bacteri but not change protein content and organoleptic characteristics (color, aroma, and mucus) of broiler chickens meat. Keywords: Sansevieria trifasciata broiler chickens meat amount of bacteri protein content organoleptic

Abstract

Minyak jelantah dapat berakibat buruk pada sistem organ. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian minyak jelantah terhadap gambaran histopatologi arteri koronaria, miokardium, dan hepar. Penelitian ini merupakan studi eksperimental dengan rancangan acak terkontrol dengan pola post test only control group design. Sebanyak 25 ekor tikus putih jantan Sprague dawley, dibagi dalam 5 kelompok perlakuan secara acak. Kelompok K (Kontrol) dan kelompok P1, P2, P3, dan P4 yang masing-masing diberikan minyak 1x, 4x, 8x, dan 12x penggorengan dengan dosis 1,5 mL/hari. Hasil penelitian didapatkan rerata diameter lumen arteri koronaria, K:147,02; P1:134,17; P2:126,16; P3:117,19 dan P4:98,28. Rerata skor kerusakan miokardium, K:0,16; P1:0,48; P2:0,96; P3:1,6; P4:1,84. Rerata skor kerusakan hepar, K:0; P1:0,2; P2:1,76; P3:2,88; P4:3,88. Hasil uji One Way Anova terhadap rerata diameter lumen arteri koronaria didapatkan p=0,001. Hasil uji Kruskal Wallis terhadap rerata kerusakan miokardium didapatkan p=0,003 dan rerata kerusakan hepar didapatkan p=0,001. Simpulan pemberian minyak goreng bekas berpengaruh buruk terhadap arteri koronaria, miokardium dan hepar. Kata kunci: arteri koronaria, hepar, minyak goreng bekas, miokardium

Abstract

Permasalahan utama yang masih terjadi di Indonesia adalah rata-rata tingkat produktivitas karet masih lebih rendah dibandingkan dengan negara pesaingnya yaitu Thailand. Ketika melakukan penyadapan, terdapat berbagai posisi kerja tidak ergonomis yang dapat menyebabkan petani menjadi lebih cepat lelah, sulit berkonsentrasi dan lambat dalam bekerja sehingga berakibat pada penurunan produktivitas. Dalam melakukan aktivitasnya, petani akan berdiri dalam waktu yang lama, berjongkok, memutar tubuh, berjinjit, dan membungkuk menyesuaikan dengan tinggi sadapan. Postur tubuh tidak ergonomis tersebut dapat memicu terjadinya keluhan Musculoskeletal Disorders (MSDs) yaitu masalah pada sistem skletal tubuh manusia. Oleh karena itu, perlu dilakukan identifikasi melalui pendekatan ergonomi berupa analisis postur kerja. Penelitian ini bertujuan untuk menganalisis tingkat risiko ergonomi postur kerja dan tingkat keparahan keluhan Musculoskeletal Disorder (MSDs) pada petani penyadap karet. Metode analisis postur yang digunakan adalah Rapid Entire Body Assessment (REBA), dikombinasikan dengan metode Nordic Body Map (NBM) untuk mengetahui tingkat risiko Musculoskeletal Disorders (MSDs) pada petani. Hasil penelitian menunjukkan bahwa tingkat risiko ergonomi postur kerja petani berada pada level 4 dengan skor REBA 12 artinya memiliki risiko yang sangat tinggi. Tingkat keparahan keluhan Musculoskeletal Disorder (MSDs) yang dirasakan oleh petani yaitu sangat sakit sebesar 77% pada leher bawah dan pinggang, 66% pada leher atas, serta 55% pada punggung dan betis.

Abstract

This study aims to partially and simultaneously analyze the influence of leverage, firm size and cash holding on profit management in property and real estate companies listed on the Indonesia Stock Exchange for the 2019-2023 period. The research method used is quantitative research. The source of the data is secondary data. The data analysis used was panel data regression analysis using the help of the Eviews version 10 program. The population in this study is property and real estate sector companies listed on the Indonesia Stock Exchange for the 2019-2023 period. The sample after selection was 17 companies in the 2019-2023 period, totaling 85 observation data. The results of this study show that partially Leverage and Cash Holding have no effect on profit management. Meanwhile, Firm Size has a significant negative effect on profit management. Simultaneously, Leverage, Firm Size and Cash Holding have a significant positive effect on profit management.

Abstract

CV. XYZ produces motor spare parts from various types of metal, spare parts that are often ordered by customers include bostep, underbone, flange and many more variations of motor spare part products that are produced. The data shows the effectiveness of the production of CV. XYZ in 2021 which is on average 100%, this proves that the achievement of production against the production plan cannot be achieved 100%. So there is often an imbalance in the production line. The purpose of this study was to determine the highest efficiency, lowest balance delay and optimal number of workstations from the production line resulting from the two methods, namely Ranged Position Wight (RPW) and Largest Candidate Rule. The type of research used in this research is comparative research. By comparing the percentage of efficiency, balance delay and number of workstations from the two methods, namely Ranged Position Wight (RPW) and Largest Candidate Rule. The data shows that the largest candidate rule method has an efficiency percentage of 107% for bostep, 85% for underbone and 94% for flange respectively. Then the smallest resulting balance delay is also generated from the production line design using the largest candidate rule method with 0.6 minutes each for bostep, 2.4 minutes for underbone and 4.3 minutes for flange. Besides that, the design of workstations using the largest candidate rule method, 2 workstations each for the bostep, 2 workstations for the underbone and 3 work stations for the flange..
