Abstract

Children with intellectual disabilities often have to deal with negative views from the surrounding environment. Negative perceptions of disability in society are often exacerbated by a lack of education and understanding about disability. This research aims to provide a clear picture of the social stigma faced by children with intellectual disabilities and how it affects their lives. This research uses the Systematic Literature Review (SLR) method. The results of this study show that there are negative viewpoints regarding stigma and discrimination in the family, community, and academic institutions. Such as the labeling of “stupid child,” “bad child,” “cursed child,” or “family burden,” often shunned, treated badly/discriminated, lack of services, such as gaps in education, health services, and social services, and lack of support for maximum growth and development in children.

Abstract

Background: Infectious diseases are still a major problem in the world, especially in developing countries, Indonesia. Objective: To determine the antibacterial activity of dadangkak root extract (Hydrolea spnosa L.) against Sterptococcus mutans bacteria using the disc diffusion and dilution methods to determine the MIC (Minimum Inhibitory Concentration) and KBM (Minimum Kill Concentration) values. Method: Extraction used the maceration method and testing for antibacterial activity used the disc diffusion and dilution methods with concentrations of 20%, 40%, 60%, 80% and 100%. Data analysis uses descriptive qualitative and quantitative. Results: Secondary metabolites produced by dadangakak root extract are: alkaloids, flavonoids, tannins and saponins which have antibacterial activity. The antibacterial activity of Dadangkak root extract (Hydrolea spinosa L.) against Streptococcus mutans bacteria using diffusion testing produced an average inhibition zone of 8.22 mm and using the dilution method to find the MIC was found at a concentration of 40%. Meanwhile, KBM was not found in all concentrations. Conclusion: Dadangkak root extract has secondary metabolites, namely: alkaloids, flavonoids, tannins and saponins. Testing of antibacterial activity using the disc diffusion method showed that there was an inhibitory zone produced, Dadangkak (Hydrolea spinosa L.) root extract had an MIC value at a concentration of 40% against Streptococcus mutans bacteria using the dilution method.

Abstract

Mahogany tree (Swietienia macrophylla king) has many benefits as an antioxidant, starting from the roots, bark, leaves, even the mistletoe that lives on this plant. Mahogany mistletoe leaves (Loranthus swietenia macrophylla) were used as samples in this study to test their antioxidant activity. This study was conducted because many have conducted antioxidant tests on mistletoe leaves such as mengkudu mistletoe leaves, coffee mistletoe leaves, mango mistletoe leaves and kersen mistletoe leaves. Mahogany mistletoe leaves (Loranthus swietenia macrophylla) were used as samples in this study to test their antioxidant activity. Before the antioxidant activity test was carried out, a phytochemical screening test was first carried out as a qualitative analysis stage to determine the secondary metabolite content in mahogany mistletoe leaves. Mahogany mistletoe leaves were dried in variations of 0 days (S), 4 days (KA4), and 8 days (KA8) which were extracted by maceration with 96% ethanol solvent. The results of the phytochemical screening test showed that mahogany mistletoe leaf extract contains secondary metabolite compounds such as flavonoids, phenolics, alkaloids, saponins, terpenoids, and steroids. The total phenolic content was 25.25; 48.29; and 52.82 mgGEA/g extract for extracts S, KA4, and KA8, respectively. Furthermore, the antioxidant activity test using vitamin C as a comparator with the DPPH (2,2-Diphenyl-1-picrylhydrazyl) method showed IC50 values ​​of 10.79; 8.00; 7.41 ppm for extracts S, KA4, and KA8, respectively, indicating that the highest antioxidant activity was possessed by sample KA 8 with an IC50 value of 7.41 ppm with a total phenolic content of 52.82 mgGEA/g

Abstract

IKM Tempe XYZ menghadapi kesulitan dalam menjaga efisiensi proses produksi. Penelitian ini bertujuan untuk mengidentifikasi pemborosan utama pada proses produksi tempe di IKM Tempe XYZ guna meningkatkan efisiensi operasional. Pendekatan dalam penelitian ini menggunakan metode deskriptif kuantitatif dengan pengumpulan data melalui kuesioner terkait adanya tujuh jenis waste. Data tersebut kemudian dianalisis menggunakan metode keputusan Borda untuk menentukan prioritas waste utama, dilanjutkan dengan analisis akar penyebab berbasis fishbonediagram untuk mengidentifikasi faktor-faktor penyebab utama dari masalah tersebut. Hasil analisis menunjukkan bahwa pemborosan transportasi akibat pemindahan bahan secara manual menjadi prioritas utama dengan skor tertinggi, yaitu 32. Pemborosan ini terjadi karena aktivitas pemindahan kedelai secara berulang akibat tata letak lokasi yang tidak efisien dan minimnya alat bantu seperti troli. Untuk mengatasi permasalahan tersebut, disarankan untuk melakukan perancangan ulang tata letak proses produksi berdasarkan alur linier yang efisien serta menyediakan troli stainless untuk mempercepat pemindahan bahan. Usulan perbaikan ini diharapkan dapat mengurangi meningkatkan produktivitas secara keseluruhan.Kata Kunci:  Metode Borda, Produksi Tempe, Pemborosan Transportasi.

Abstract

This study aimed to reduce transportation waste in tempeh production by integrating Lean Manufacturing tools with facility layout optimization and to evaluate the resulting operational and economic improvements. The study employed a descriptive quantitative case study conducted at a traditional tempeh production facility in Bandung, Indonesia. Waste identification was carried out using the Seven Waste framework and was prioritized using the Borda Count method. Lean tool selection was guided by the Value Stream Analysis Tool (VALSAT). Process analysis was conducted using Value Stream Mapping (VSM), Process Activity Mapping (PAM), and Root Cause Analysis (RCA). Facility layout optimization was performed using the Systematic Layout Planning framework, supported by Activity Relationship Charts and the Blocplan algorithm. Improvement effectiveness was evaluated using Future Process Activity Mapping (FPAM), Future Value Stream Mapping (FVSM), and Operator Material Handling (OMH) cost analysis. The results showed that transportation waste was the dominant inefficiency in the production system. The layout redesign reduced transportation time by approximately 57% and total material handling distance by 19%, while value-added processing time remained unchanged. These improvements generated measurable cost savings based on the OMH metric.
