Judul: Design Concept of Rotary Type Nutmeg Mace Machine
Abstrak: Pala merupakan tanaman rempah asli Indonesia dan telah diperdagangkan dan dibudidayakan pada perkebunan rakyat. Pala menghasilkan dua produk bernilai ekonomi tinggi, yaitu biji pala dan fuli atau kembang pala yang menyelimuti biji yang memiliki kandungan minyak atsiri yang tinggi. Salah satu proses penangan pascapanen biji pala, yaitu pengupasan fuli dari biji pala. Usaha yang dapat dilakukan untuk meningkatkan proses penanganan pascapanen pala ini, yaitu merancang mesin yang dapat meningkatkan kapasitas penanganan proses. Tujuan dari penelitian ini adalah membuat konsep desain mesin pemisah fuli biji pala tipe rotari. Penelitian ini menggunakan pendekatan rancangan fungsional dan struktural. Perancangan dilakukan pada komponen hopper, silinder pemisah, dan sistem pengumpanan. Melalui dasar perancangan mesin untuk kapasitas 10 kg, hasil analisis komponen yang diperoleh, di antaranya volume hopper 77,91 L, silinder pemisah berdiameter 0,29 m dengan panjang 0,5 m, sistem pengumpanan menggunakan screw conveyor dan sistem transmisi daya listrik 0,75 kW menggunakan sabuk dan puli., Nutmeg is an Indonesian native spice plant and has been cultivated and traded by smallholder plantations. Nutmeg has two high economic value products, namely nutmeg seeds and nutmeg mace that envelop seeds and have high content of essential oils. One of nutmeg post-harvest process is peeling nutmeg mace from nutmeg seeds. Efforts should be made to improve this post-harvest process by designing a machine that can increase peeling process capacity. The purpose of this research was to develop a design concept of design of rotary type nutmage mace peeling machine. This research was conducted using functional and structural design approach. Design was carried out on hopper component, separator cylinder, and feeding system. Base on 10 kg per batch of designed machine capacity, the results of the analysis of components obtained were 77,91 L of hopper volume, 0,29 m of diameter and 0,5 m of length for separtor cylinder dimension, screw conveyor as feeding system, and belt and pulley as transmission system of 0,75 kW electric power.

Judul: Design and Simulation of Red Beans External Peeler Machine with Spoke Type Beater
Abstrak: Rancangan mesin pengupasan polong kacang merah tipe dual roll dan sistem bantingan dinilai kurang efektif dikarenakan pengupasan untuk setiap polong hanya dilakukan satu kali. Penelitian ini bertujuan merancang dan menyimulasikan mesin pengupas kulit luar kacang merah tipe ruji. Penelitian dilakukan dengan pendekatan desain fungsional dan struktural yang terdiri dari tahap identifikasi masalah, perumusan konsep desain, analisis teknik, gambar teknik serta simulasi. Simulasi Finite Element Analysis (FEA) menunjukkan bahwa stress pada hopper sebesar 3% dari yield strength. Ruang pengupas mengalami defleksi maksimum sebesar 0,13 mm, sedangkan rangka mengalami defleksi 0,1 mm. Keduanya berada dibawah batas maksimum 2 mm. Hasil simulasi Discret Element Methode (DEM) pada hopper mampu mengalirkan polong dengan laju rata rata sebesar 0,0249 kg/s. Simulasi computational fluid dynamic (CFD) menunjukkan bahwa rancangan debit udara sebesar 0,5 m3/s pada ruang pengupas mampu memberi gaya dorong hingga 0,153 N, sementara pada ruang pemisah menunjukkan bahwa debit harus ditingkatkan dari 0,0171 m3/s menjadi 0,021 m3/s untuk memperoleh gaya dorong sebesar 0,004 N. Berdasarkan laju massa polong diperoleh kapasitas kerja mesin sebesar 89,64 kg/jam., The design of the dual roll type red bean pod peeling machine and rotary impact is considered less effective because the stripping for each pod is only done once. The purpose of this study was to design and simulate red bean external peeler machine with spoke type beater. The research was conducted with a functional and structural design approach consisting of problem identification, design concept formulation, technical analysis, engineering drawings and simulations. Finite Element Analysis (FEA) simulation shows that the stress on the hopper is 3% of the yield strength. The peeler chamber component experienced a maximum deflection of 0.13 mm, while the frame experienced a deflection of 0.1 mm. Both are below the maximum limit of 2 mm. The simulation results of the Discret Element Method (DEM) on the hopper were able to drain the pods at an average rate of 0.0249 kg/s. Computational fluid dynamic (CFD) simulations show that the designed air flowrate of 0,5 m3/s in the stripper chamber is able to provide a thrust of up to 0.153 N, while in the separator chamber it shows that the flowrate must be increased from 0,0171 m3/s to 0,024 m3/s to obtain a thrust of 0.004 N. Based on the mass rate of the pods obtained a working capacity of 89.64 kg/hour machine.

Judul: Studi Kasus Liver Neoplasia pada Anjing Shih Tzu
Abstrak: Liver neoplasia is the excessive and uncontrolled replication of hepatocytes that forms nodules visible in ultrasonography. The purpose of this study is to study and discuss the characteristic, diagnosis and treatment of liver neoplasm through the interpretation of ultrasonography and hematology in a Shih Tzu dog. Ultrasonography is conducted with a Chison Q8 ultrasound machine with a 5 to 7 MHz frequency convex probe on lateral recumbency. The blood cells, liver enzymes and nodules sizes were the main parameters in this study. The results in the period of three years from 2021 to 2023 were interpreted and supported with secondary data sources. The Shih Tzu dog is 14 years old in the year 2023 with a body weight of 5.21kg. No obvious clinical signs were observed during previous examinations. However, lethargy, vomiting and anorexia were recorded in its latest examination. Thrombocytosis, granulocytosis, high liver enzymes and hypoglycemia, which are some of the neoplastic clinical manifestations were also presented by this patient. Besides, liver neoplasm, spleen neoplasm and biliary sludge were the sonogram findings of this patient. The liver and spleen neoplasm was observed stable, while the biliary sludge volume fluctuated. The treatment strategy recorded is Ondansetron, Samylin®, Ornipural and Ursodeoxycholic acid.
