Abstract

Annona is a genus belongs to Annonaceae family, consisting of numerous species that produce edible fruit.   Four species namely A. glabra, A. montana, A. muricata and A. squamosa collections of Purwodadi Botanic Garden  were recorded for its flowering and fruiting times, since November 2010 to April 2013. The data were scored and complemented with climate data (temperature, rainfall intensity, humidity) then analyzed using multiple linear regression analysis.  The result showed that humidity was the most affected climate factors on the flowering and fruiting times of those species.  Specifically, rainfall intensity (0-550 mm) affected to  Annona muricata, temperature (25,56-28,33 °C) and humidity (66,83-85,02%) to  Annona squamosa, and  humidity to  A. glabra (71,62-85,02% )  and  A. montana (71,62 to 82,94 %) as well. Flowering time of A. glabra occurs three times a year in wet and dry, and fruiting occurs twice a year in the same month. Annona muricata is flowering throughout the year and fruiting twice a year in wet. A. montana and A. squamosa recorded one a year during the wet month.

Abstract

Tujuan penelitian ini adalah untuk mengetahui seberapa besar pengaruhnya tunjangan kinerja dan lingkungan kerja terhadap kinerja pegawai pada Badan Kepegawaian Daerah Kabupaten Bima. Hal ini terlihat dampak besarnya tunjangan kinerja terhadap beban kerja, kurangnya perilaku kedisiplinan kehadiran dan motivasi  pegawai, sulit untuk naik kelas jabatan ke yang lebih tinggi bagi pegawai. Jumlah sampel yaitu sebanyak 39 orang dengan menggunakan teknik pengambilan sampel purposive sampling yaitu hanya ASN yang bekerja pada Badan Kepegawaian Daerah Kabupaten Bima. Berdasarkan hasil analisis data diketahui bahwa tunjangan kinerja dan lingkungan kerjaberpengaruh terhadap kinerja pegawai.

Abstract

PT XYZ is a manufacturing company that produces motorcycle and car spare parts, during the production process, there is still a level of product defect that needs to be controlled, especially in one of the products with the highest production volume during the period of July–December 2024. This study was conducted to determine the level of damage, identify the factors causing the damage and recommend corrective actions. The method used is the Statistical Quality Control (SQC) method using statistical tools including: checksheet, histogram, pareto diagram, P-Chart, and fishbone diagram. The results of the study showed that the most product defects occurred in the short print defect type (36.61%), followed by appearance (17.42%), movement (16.08%), electric (15.77%), printing feel off (8.45%), and skip printing (5.67%). Actions taken to minimize the level of defects include conducting periodic training for operators in terms of part checking and handling procedures, compiling a visual and final inspection checklist to ensure that no steps are missed, adding a handle to the tray to prevent direct hand contact with the part/material, implementing a part inspection checklist before use including checking the dryness of the cavity, performing surface treatment such as wiping and drying the part/material before the printing process, using a cover on the part.

Abstract

Quality control is a critical aspect of the manufacturing industry to ensure that every product meets the specified requirements. PT XYZ, as an automotive component manufacturer, faces the problem of a high number of defective products in the Side Member Assy RR Floor component. This study aims to analyze the quality control process using the Statistical Quality Control (SQC) method with the Seven Tools approach. The research methods include data collection through observation and documentation, followed by analysis using tools such as control charts, checksheets, histograms, Pareto diagrams, scatter diagrams, fishbone diagrams, and flowcharts. The results show that the dominant type of defect is spatter, accounting for 83.7% of total defects. Control chart analysis indicates that the process is not fully under control, as evidenced by data points falling outside the control limits. Fishbone analysis reveals that the main causes of defects originate from non-standardized work methods and insufficient operator skills. As a concrete improvement measure, Standard Operating Procedure (SOP) documents and Visual Inspection Checklist forms were developed. This study provides a tangible contribution by assisting the company in improving product quality and systematically reducing defect rates.
