Abstract

Penetratif entrainment pada aliran air mancur transisi dan turbulen merupakan fenomena penting yang memengaruhi efisiensi energi dan distribusi massa dalam berbagai aplikasi teknik, seperti sistem pendinginan dan rekayasa lingkungan. Permasalahan utama dalam studi ini adalah kurangnya pemahaman kuantitatif mengenai mekanisme entrainment pada kondisi aliran dengan variasi densitas dan kecepatan yang kompleks. Penelitian ini bertujuan untuk mengevaluasi laju aliran entrainment penetratif menggunakan pendekatan Computational Fluid Dynamics (CFD). Simulasi dilakukan dalam ruang berdimensi 40 cm × 30 cm × 20 cm dengan pemodelan mesh tetrahedral, menghasilkan 21.839 node dan 81.742 elemen. Dua inlet dengan densitas berbeda digunakan: 997 kg/m³ pada ketinggian 18 cm dan 1.100 kg/m³ pada ketinggian 0 cm, guna merepresentasikan kondisi transisi hingga turbulen. Hasil simulasi menunjukkan bahwa laju entrainment meningkat signifikan seiring kenaikan bilangan Reynolds. Pada outlet (ketinggian 0 cm), diperoleh densitas 1.021,2 kg/m³, laju aliran volumetrik 26.729,3 mm³/s, dan bilangan Reynolds sebesar 1.381,91, yang mengindikasikan kondisi aliran laminar. Hal ini menunjukkan bahwa mekanisme entrainment lebih didominasi oleh difusi massa daripada turbulensi dalam kondisi ini. Penelitian ini memberikan gambaran tentang pengembangan sistem yang efisien untuk aplikasi dengan aliran rendah hingga menengah. Implikasinya, desain sistem pendinginan dan pengolahan air dapat dioptimalkan dengan mempertimbangkan karakteristik entrainment pada berbagai kondisi aliran

Abstract

The synthetic eyelash manufacturing industry in Indonesia, particularly PT Hyup Sung Indonesia (HSI) in Purbalingga, faces ongoing challenges in maintaining product quality due to a high incidence of defects. This study aims to analyze and mitigate production-related risks through the application of Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA). FMEA is utilized to systematically identify potential failure modes and prioritize improvement efforts based on the Risk Priority Number (RPN), while FTA is employed to trace the root causes of critical failures in a hierarchical structure. The FMEA results identified three major failure modes with the highest RPN values: knot misalignment during opening (RPN 150), insufficient application of adhesive (RPN 140), and curling of the knot during opening (RPN 140). FTA revealed that these issues primarily arise from equipment-related factors, operator handling methods, and inconsistencies in the oven-setting process. Based on these findings, several corrective actions are proposed, including the replacement of production tools (racks and brushes), installation of automatic timers, standardization of operating procedures, and operator training programs. The implementation of these measures is expected to reduce the risk of production failures and enhance the overall quality of synthetic eyelash products

Ketidaksesuaian antara data persediaan dalam sistem dengan stok aktual di gudang dapat menghambat operasional dan meningkatkan biaya pada perusahaan manufaktur. Penelitian ini dilakukan di PT XYZ, untuk menganalisis faktor penyebab ketidaksesuaian dalam stock opname dan mengusulkan perbaikan guna meningkatkan akurasi pencatatan persediaan. Tujuan dari penelitian ini untuk mengidentifikasi faktor penyebab terjadinya ketidaksesuaian stok dan mengusulkan perbaikan untuk meningkatkan akurasi pencatatan. Metode yang digunakan adalah DMAI (Define, Measure, Analyze, Improve) yang dikombinasikan dengan pendekatan Kaizen untuk perbaikan berkelanjutan. Hasil penelitian menunjukkan bahwa ketidaksesuaian stok disebabkan oleh pencatatan yang tidak akurat, ketidaksesuaian data sistem dengan kondisi fisik, serta kesulitan dalam pelacakan barang. Faktor utama yang berkontribusi meliputi kurangnya disiplin dalam prosedur pencatatan, lingkungan gudang yang kurang optimal, serta tidak adanya sistem penyimpanan yang terstruktur. Untuk mengatasi permasalahan ini, diterapkan prinsip 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) guna meningkatkan efisiensi dan akurasi pencatatan stok. Implementasi usulan perbaikan ini diharapkan dapat mengurangi selisih antara stok sistem dan stok aktual, serta meningkatkan efisiensi operasional perusahaan.

Abstract

Tahu merupakan salah satu makanan yang banyak digermari masyarakat Indonesia. Selain rasanya yang enak tahu juga menyimpan banyak protein yang baik untuk tubuh. Pembuatan tahu menggunakan bahan baku kacang kedelai yang kemudian dihancurkan dan dibentuk ulang seperti menyerupai bentuk kotak. Selain itu tahu juga bisa diolah menjadi berbagai macam masakan. Desa Kalisari Kecamatan Cilongok Kabupaten Banyumas merupakan desa sentra pembuatan tahu. Sebagian besar penduduk desa kalisari memiliki mata pencaharian sebagai produsen tahu. Tahu yang dibuat perhari bisa mencapai 50 hingga 100kg untuk 1 produsen tahu rumahan. Pembuatan tahu tersebut tidak lepas dari limbah tahu yang biasanya akan dibuang atau menjadi campuran bagi pakan ternak. UKM Suwardi merupakan salah satu UKM yang memiliki inisiatif mengolah limbah tahu menjadi makan yang memiliki nilai lebih. Salah satu produk yang dihasilkan oleh UKM Suwardi adalah krupuk ampas tahu. Usaha pembuatan kerupuk ini sudah berjalan sejak tahun 2011 hingga kini. Kerupuk banyak dipasarkan di sekitan Kabupaten Banyumas bahkan Jawa Tengah. Adanya pandemi membuat ekonomi dari usaha kerupuk ampas tahu menjadi tidak stabil. Akibat tidak ada produksi dalam waktu yang lama membuat mesin produksi yang biasa digunakan untuk memotong adonan kerupuk menjadi berkarat dan tidak higenis. Pengabdian ini bertujuan untuk membuat dan mendampingi dalam pembuatan mesin kerupuk ampas tahu yang lebih higenis sehingga kualitas dari produk krupuk ampas tahu bisa lebih baik lagi.

Abstract

The increasingly rapid development of technology has led to the emergence of mobile commerce (m-commerce) as a new business phenomenon. Tokopedia and Shopee are m-commerce that are widely used by Indonesian people compared to other m-commerce. However, the Tokopedia and Shopee applications still have problems such as crashes, errors, buffering, bugs, an unfriendly and messy UI display, search features that are not suitable or working properly, unhelpful customer service, and other user complaints felt by users towards service quality. The existence of these complaints can create a gap between the services provided by the application and the services expected by users. Therefore, this research was conducted to determine the quality of service on the Tokopedia and Shopee applications by measuring service quality using the M-S-QUAL method and identifying priority service attributes that require improvement using the Importance-Performance Analysis (IPA) method. Research data was obtained from the results of questionnaires to 100 respondents who used Tokopedia and Shopee. Based on the calculation results, the Tokopedia and Shopee applications have a negative average gap value in all dimensions, meaning that the service quality of the Tokopedia and Shopee applications has not met the expectations of their users. Then, the results of the analysis using Importance Performance Analysis (IPA) obtained 8 attributes on Tokopedia (EF2, EF3, EF5, EF7, EF8, SA3, SA4, and CON3) and 8 attributes on Shopee (EF5, EF7, EF8, SA3, SA4, COM3, CON2, and CON3) which are the main priorities for improvement. Thus, these attributes will be given recommendations for improvement to increase or improve the quality of the service.

Abstract

In the current era of regional autonomy, regional economic development should be conducted sustainably across all fields, sectors, and sub-sectors in a programmed manner. Sustainable regional economic development is influenced by comparative advantages, regional specialization, and the economic potential of a particular area. The primary objective of regional economic development is to enhance the well-being of the community through an increase in the quantity and variety of job opportunities. Empowering Small and Medium Enterprises (SMEs) is one way to boost employment opportunities, involving a significant workforce and identifying competitive sectors in the region to enhance regional economic development. Boyolali Regency has shown relatively good growth in SMEs; however, there is a lack of mapping for basic sectors within these SMEs. This absence may lead to suboptimal utilization of available labor and production outcomes. Therefore, this research aims to identify and map SMEs with the potential to absorb more labor in Boyolali Regency. The Location Quotient (LQ) method is utilized to identify basic and non-basic types of SMEs using labor data from SMEs in Boyolali Regency. LQ calculations demonstrate that each SME has various basic sectors. This analysis produces mapping data of basic SMEs that can be used as a reference for more targeted development in SMEs, leading to increased job absorption.

Abstract

An integral aspect of anticancer experimentation involves delineating the optimal dosage of the test compound to ascertain its efficacy in targeting malignant cells. Numerous variables may influence a compound's cytotoxicity, among which is the choice of cell culture medium. Within in vitro settings, supplementary mediums are employed to foster cellular proliferation. Platelet lysate (PL) serves as a growth supplement, presenting an alternative to fetal bovine serum (FBS), primarily due to its incorporation of growth factors such as platelet-derived growth factor (PDGF), a component absents in FBS. The integrity of PL may be subject to various factors, including the age of the donor. This study sought to evaluate the impact of donor age on PL quality. Furthermore, it aimed to discern whether PL derived from platelet concentrate (PC) blood components of different age cohorts influences the IC50 value in anticancer compound assessment. Expired PCs were utilized, subsequently classified into age categories: ≤30 years, >30 years, and a combination of ages. PL analysis encompassed parameters such as pH, blood profile, protein, glucose, and cholesterol levels. The investigation scrutinized the influence of PL quality, as a cellular growth supplement, on the anticancer compound cisplatin's activity against HeLa cells. Findings indicate that donor age influenced the IC50 value of cisplatin on HeLa cells. Notably, elevated cholesterol levels and decreased pH in PL from donor ages >30 years were associated with reduced cisplatin toxicity.Keywords: Cisplatin, Donor Age, HeLa, IC50, Platelet Lysate.
