Abstract

Concentration is essential in order to help to perceive and understand the object that is being focused. If students can concentrate, everything can be recorded properly in the brain's memory. If student concentration experiences obstacles in learning activities, there will be obstacles to achieve goals. This study aims to analyze the influence and relationship between concentration levels when listening to different audio stimuli. The methods that can be used quantitatively to see learning concentration are reaction time and memory recall methods for 30 students. The data obtained are processed using statistical tests, that is the T test and ANOVA test to test the differences in sample means from different variables and draw conclusions by finding different data groups. Based on the results of the T test, giving the three audio stimuli to men did not provide a significant average difference in reaction speed. Meanwhile, for female respondents, only the favorite song stimulus had a significant average difference. There is no significant difference in memory recall ability to audio stimulus. For the male respondents, the instrumental stimulus was the most effective stimulus, while for the female, the favorite song stimulus was the most effective.

Abstract

Kelelahan kerja merupakan salah satu gangguan kesehatan yang dialami oleh pekerja akibat pekerjaan. Kelelahan karena aktivitas kerja berulang dapat memunculkan risiko cedera tubuh. Salah satu aktivitas fisik yang terjadi dalam proses pengolahan hasil ternak yaitu pengangkutan bahan baku, pengolahan hasil ternak, hingga aktivitas pengemasan. Pekerja pengolahan hasil ternak dihadapkan pada faktor fisik di tempat kerja yang meliputi postur janggal saat bekerja, mengangkat beban berat, mengerahkan tenaga yang besar, dan melakukan kegiatan yang berulang. Risiko tersebut apabila tidak diperhatikan dapat menyebabkan pekerja mengalami cedera seperti nyeri, mati rasa, bengkak, kekakuan, dan lain-lain yang secara langsung dapat mempengaruhi produktivitas.Pengabdian kepada masyarakat ini dilakukan dengan tujuan untuk meningkatkan pengetahuan pekerja agar dapat bekerja dengan lebih aman, nyaman dan produktif dengan menerapkan prinsip-prinsip penanganan material secara manual dengan memperhatikan bahaya ergonomi, sehinga dapat mengurangi risiko gangguan otot rangka akibat kerja. Adapun metode yang digunakan untuk mengukur tingkat perubahan pengetahuan pekerja dengan melakukan pre-test dan post-test. Berdasarkan hasil pengukuran pre-test sebanyak 24 pekerja menjawab pertanyaan dengan jawaban 80% benar, kemudian setelah diberikan penyuluhan dan dilakukan post-test hasil menunjukkan adanya peningkatan bahwa seluruh pekerja di departemen produksi dapat menjawab >80% jawaban benar. Kesimpulannya setelah dilakukan pre-test dan post-test pada 37 pekerja menunjukkan bahwa terjadi peningkatan pengetahuan terkait bahaya ergonomi dan risiko gangguan otot rangka akibat kerja (gotrak).

Abstract

The advancement of technology in the construction materials industry sector is rapid, so that it is always necessary to innovate in order to create material products that are in line with current construction trends. PT. XYZ is a construction materials company that manufactures lightweight bricks using the Autoclaved Aerated Concrete (ACC) system. Many problems were discovered during the lightweight brick production process that did not match the quality of lightweight brick products with the standards set by the company. This study aims to identify the types of defects in lightweight brick production; determine the current sigma value (baseline) in lightweight brick production; identify the factors that cause defective products; and propose appropriate improvement to minimise defects and reduce losses caused by high defect rates in order to meet KPIs. According to the Pareto diagram analysis, the defects with the highest priority for repair are fracture (55.78 percent), cracked (30.65 percent), and broken (13.57 percent). The sigma level of lightweight brick production at PT. XYZ is 3.32, with the largest defect being 57,708 lightweight brick items per million opportunity of production. Based on the analysis of the Fishbone diagram, the potential factors that cause defective products are humans, machines, materials, methods, and measurements. The proposed improvements in the Improve stage are based on the results of the analysis using the Failure, Mode, and Effect Analysis (FMEA) method, where the company can determine appropriate preventive actions and improvements to reduce defective products and increase competitiveness.

Abstract

Plastic bag is a product that is very often used in everyday life. Plastic bags are one of the biggest contributors to the volume of waste in Indonesia. Therefore, a policy related to the use of plastic bags is called a zero plastic bag. This policy requires plastic bag users to switch to using environmentally friendly bags. This study was conducted to analyze the effect of the zero platic bag policy on Makassar City community behavior related to the environment or green behavior if this policy is applied in the City of Makassar. To determine the effect of the zero plastic bag policy on people's behavior patterns about the environment using the SEM (Structural Equation Modeling) method. Initial identification was carried out by distributing questionnaires to respondents using plastic bags, especially retail consumers in Makassar City. The questionnaire contained green behavior variables which consisted of five variables. Then the results of data collection using a questionnaire are processed using descriptive analysis and then look for the effect of zero plastic bag policies on green behavior using the SEM method. The results of the identification of the influence of zero plastic bag policy based on four variables namely environmental knowledge, environmental attitude, green advertising, and green consumption on green behavior are that of the four variables that have a positive influence on green behavior are environmental attitude, green advertising, and green consumption . The results of this study can be used as policy input and see how effective this policy is when applied in Makassar City.
