Perbaikan Kinerja Supply Chain Perusahaan Keripik Singkong Berdasarkan Analisis Product Availability

Level ketersediaan produk menjadi permasalahan pada objek penelitian ini karena adanya fluktuasi dan ketidak- pastian permintaan dari konsumen yang timbul ketika pelaku USAha telah menentukan cycle service level. Hal ini menjadi indikator kinerja supply chain dalam memenuhi ketersediaan produk dan menghindari kekurangan stok atau- pun kelebihan stok di siklus replenishment. Penelitian dilakukan di UD As-Salam, dan bertujuan untuk memperbaiki kinerja supply chain dari sisi product availability. Perlu ditetapkan optimal level of product availability agar mampu mengoptimalkan profit. Metode yang digunakan adalah dengan penentuan optimal cycle service level, optimal order size, expected profit, dan analisis sensitivitas terhadap optimal cycle service level dengan expected profit. Hasil peneli- tian menunjukan bahwa nilai cost of understocking adalah Rp 4.144,00 dan cost of overstocking adalah Rp 6.573,00. Nilai optimal cycle service level dapat dicapai pada level 63% dengan optimal order size 2.842 kg per bulan. Nilai ini mampu memberikan profit sebesar Rp 11.043.570,00. Peningkatan kinerja berdasarkan analisa product availability akan memberikan peningkatan profit sebesar Rp 127.891,00 pada Perusahaan

Robots, Everlasting? A Framework for Classifying CS Educational Robots

Educational robots are an exciting and growing field. While some (Lego Mindstorms, for example) have been around for decades, most are only a few years old and their durability is untested; exacerbating this are those only usable with apps, that may become suddenly unavailable. This has created a nascent but significant problem: schools investing significant time and money for educational robots with little ability to know if they will work for years or just days. Other fields in science, technology, education, and math (STEM) beyond computer science also encounter this issue as more educational robots and apps for those disciplines permeate the market. While this chapter analyzes this issue from a CS perspective, the lessons learned can be applied to other STEM areas. This chapter explores the history of the problem, documents several examples of devices that have succumbed, details the unique and specific needs of school customers, and introduces the Computer Science Risk Analysis Framework for Toys (CS RAFT) to help teachers and schools evaluate a device purchase based on a holistic understanding of device longevity. This study will also provide recommendations for CS and STEM educational robot designers

New physics, the cosmic ray spectrum knee, and pppp cross section measurements

We explore the possibility that a new physics interaction can provide an explanation for the knee just above $10^6$ GeV in the cosmic ray spectrum. We model the new physics modifications to the total proton-proton cross section with an incoherent term that allows for missing energy above the scale of new physics. We add the constraint that the new physics must also be consistent with published $pp$ cross section measurements, using cosmic ray observations, an order of magnitude and more above the knee. We find that the rise in cross section required at energies above the knee is radical. The increase in cross section suggests that it may be more appropriate to treat the scattering process in the black disc limit at such high energies. In this case there may be no clean separation between the standard model and new physics contributions to the total cross section. We model the missing energy in this limit and find a good fit to the Tibet III cosmic ray flux data. We comment on testing the new physics proposal for the cosmic ray knee at the Large Hadron Collider.Comment: 17 pages, 4 figure

Simulasi Kebijakan Penambahan Areal Tanam dan Peningkatan Produktivitas dalam Mendukung Tercapainya Swasembada Jagung

Corn is one of five main commodities that is expected to achieve self-sufficiency at the end of RPJMN 2019. However, the gap between supply and demand capacities was still quite large, so that imports are still conducted. The government through the Ministry of Agriculture issued a self-sufficiency policy through extensification and intensification, with the scenario of Planting Areas increase (PAT) of up to 3 million Ha, and productivity increase of up to 53.18 Ku/Ha. This study aims to: (1) measure the achievement of national corn self-sufficiency by establishing a model of national corn availability dynamic system before and after the self-sufficiency policy; (2) develop some policy alternatives for corn self-sufficiency. This article used a dynamic system approach based on secondary data from the Ministry of Agriculture and BPS, determined dynamic hypotheses and systems models, made causal loop diagrams, calculated stock flow diagrams, and validated and verified the models. The results of validation and verification illustrated that the model was made in accordance with the actual conditions that exist. The simulation results showed that increasing the cropping index can continuously achieve maize self-sufficiency until 2019, as well as the scenario of realistic, optimistic extensification (PAT) and the combination of realistic and intensification

Imaging Flow Cytometry With Femtosecond Laser-Micromachined Glass Microfluidic Channels

Microfluidic/optofluidic microscopy is a versatile modality for imaging and analyzing properties of cells/particles while they are in flow. In this paper, we demonstrate the integration of fused silica microfluidics fabricated using femtosecond laser machining into optofluidic imaging systems. By using glass for the sample stage of our microscope, we have exploited its superior optical quality for imaging and bio-compatibility. By integrating these glass microfluidic devices into a custom-built bright field microscope, we have been able to image red blood cells in flow with high-throughputs and good fidelity. In addition, we also demonstrate imaging as well as detection of fluorescent beads with these microfluidic devices
