Abstract

Penelitian ini bertujuan untuk mengetahui nilai Six Sigma serta bagaimana pelaksanaan pengendalian kualitas menggunakan metode Six Sigma. Dari hasil pengukuran data yang diperoleh pada bulan Januari 2022 bahwa untuk Critical to Quality (CTQ) kunci Bedasarkan data perhitungan dengan Peta kendali P didapatkan hasil CL sebesar 0,099, UCL sebesar 0,357, LCL sebesar -0,160 artinya jenis Defect masih berada dalam batas kendali perusahaan. Dan bedasarkan data perhitungan Level Sigma sebelumnya didapatkan hasil OP sebesar 105, TOP 1260, DPO 0,357 dan DPMO sebesar 357,145 dengan  rata-rata 3,4 sigma tingkat kesuksesannya yaitu 97,13% yg artinya nilai sigma berada di rata-rata industri indonesia. Bedasarkan diagram pareto, bahwa 54% untuk  Daun dan 39% untuk cacat Blemish. Untuk nilai sigma pada produksi bulan Januari adalah 3,4 sigma, Kemudian dilanjutkan dengan menganalisa penyebab cacat Daun dan Blemish dengan menggunakan diagram sebab akibat dan usulan rencana perbaikan. Dari analisis diagram sebab akibat bahwa faktor penyebab kecacatan berasal dari faktor lingkungan, material, dan  manusia. Setelah  itu dengan  usulan rencana perbaikan dapat diketahui bahwa penyebab kegagalan adalah  lingkungan, material, manusia pada saat proses produksi berjalan. Untuk upaya perbaikan dari permasalahan tersebut maka diperlukan pemeriksaan kondisi lingkungan, material dan manusia.

Abstract

This research aims to measure the extent of the impact of the Zakat distribution program in the education sector by taking a case study of the BAZNAS Cendekia School (SCB) program. This research was conducted using an evaluative approach with the Sustainability Livelihood Impact Assessment (SLIA) framework. Data collection was carried out through literature study, field observations, in-depth interviews. The sample population for this research was comprehensive (total sampling) consisting of 21 school management people, 26 teaching staff, 277 students and 30 heads of local families. The findings from this research show that there has been an increase in all aspects of SLIA with various scales of change, namely the human resource capital aspect of 0.30, social capital of 0.25, natural resource capital of 0.30, physical capital of 0.25 and financial capital of 0.41. The highest change occurred in the financial capital aspect of 0.41 and the lowest change occurred in the social and physical capital aspect. This shows that during the 2017-2020 period, the current social and financial modalities are aspects that are felt to be very useful at this time, so in the future the minimum contribution achieved in this aspect can be maintained. Meanwhile, regarding the aspects of human resource, natural resources and physical modalities, these three aspects need to receive attention to improve optimization so that these already good assets can be more optimally useful for all parties who have an interest in the sustainability of SCB for better education. A limitation of this research is the unavailability of baseline data to measure how big the stakeholder and beneficiary perception scores were at the start of the program. Because this research was conducted in the 3rd year after the SCB started, of course the perception comparison between then and now has the potential for quite large bias.

Abstract

Highlights: • Sodium diclofenac is one of NSAID a common treatment to relieve pain associated with bone fractures. • Sodium diclofenac with a some dose of body weight could decrease the callus quality on fracture healing. Abstract: Non-steroidal anti-inflammatory drugs (NSAIDs), such as diclofenac sodium, are standard treatments to relieve pain associated with bone fractures. The bone healing process consists of four stages: inflammation, soft callus formation, complex callus formation, and bone remodeling. Previous studies mentioned that intake of NSAIDs (sodium diclofenac) could inhibit the bone healing process. This study examined the effect of diclofenac sodium intake on callus formation in fracture healing. In this study, thirty-six rats (Rattus Norvegicus) with fractures were used and divided into two groups, namely 18 rats for the control and 18 rats for the treatment group. In the treatment group, each rat was given 1.8 mg sodium diclofenac/150 grams of body weight per day. In the control group, each rat was given CMC-Na 0.5% with equal volume as diclofenac sodium in the treatment group. After 28 days, all the rats were stunned until dead, and the diameter and strength of their calluses were measured. In the treatment group with diclofenac sodium1.8 mg/ 150 grams BW/ 28 days after the tibia bone callus was pressed using the Shimadzu tool, the lowest callus strength was found to be 56.500 N, and the highest callus strength was 59.000 N. The lowest callus diameter in the treatment group was 4 mm, the highest was 5 mm. In the control group, the lowest callus strength was 76 N, and the highest callus strength was 77 N. The lowest callus diameter in the control group was 6 mm, and the highest was 8 mm. The strongest callus in the treatment group was found in the sixth observation, with a value of 59 N and a diameter of 4 mm. In the control group, the highest callus strength was 77 N, with a diameter of 7-8 mm. These measurements were found on the 5th, 7th, 8th, 9th, 16th, and 17th observations. Diclofenac sodium with a dose of 1.8 mg/150 grams of body weight could decrease the callus quality parameters, such as callus strength and diameter on fracture healing.

Abstract

Highlights: 1. Novel synthetic biopolymer hydrogels were successfully prepared from pristine poly(ethylene glycol) dimethacrylate (PEGDMA) and nanofibrillated cellulose (NFC) using the photopolymerization method. 2. PEGDMA-NFC biocomposite hydrogel can be developed as an affordable biomaterial for herniated nucleus pulposus substitute, with the potential to meet clinical application standards. Abstract Herniated nucleus pulposus develops when the intervertebral disc portudes through the annulus fibrosus due to the rupture of the annulus fibrosus or a decrease in proteoglycans. Hydrogel implant material can be injected into the disc space to restore disc thickness caused by disc degeneration with minimal invasiveness. This study aimed to characterize poly(ethylene glycol) dimethacrylate-nanofibrillated cellulose (PEGDMA-NFC) in vitro as a potential biomaterial for herniated nucleus pulposus substitute. This study utilized PEGDMA-NFC to treat first-degree herniated nucleus pulposus using the photopolymerization method. PEGDMA was selected because of its hydrophilic ability to produce hydrogel. The addition of NFC to the PEGDMA precursor was expected to show mechanical properties as a hydrogel bio composite candidate. The characterization of PEGDMA-NFC was conducted using three tests: Fourier-transform infrared spectroscopy (FTIR), viscosity assessment, and an in vitro injection testing model. The normal distribution of the data was analyzed using the Kolmogorov-Smirnov test, while the homogeneity was assessed using Levene's test. Homogenous and normally distributed data were analyzed using a one-way analysis of variance (ANOVA) with a p-value of <0.05. The explored concentrations of PEGDMA-NFC included a ratio of 1:0 for the control samples and ratios of 1:0.5 (K1), 1:0.75 (K2), and 1:1 (K3) for the experimental samples. The FTIR analysis revealed the presence of various functional groups in PEGDMA-NFC, indicating its potential classification as a hydrogel biomaterial. The characterization data showed that the K3 sample yielded the most favourable outcome with a viscosity value of 74.67 dPa·s. From the in vitro injection testing result, the addition of NFC demonstrated that the hydrogel would not rupture when released from the mold. The hydrogel could be injected with an 18 gauge needle. The statistical analysis results showed a significant difference among the samples (p<0.05). This study concludes that the PEGDMA-NFC hydrogel biocomposite can be effectively applied in herniated nucleus pulposus cases.
