Research on a reference signal optimisation algorithm for indoor Bluetooth positioning

GPS has a sharp performance decline in terms of accuracy indoors due to the complex building structure. A combined algorithm, targeting at received signal strength indication (RSSI) calibration optimisation, depending on deep neural network training via input vector Γ and the target output vector Ψ, termed reference signal optimisation algorithm (RSOA) is proposed to improve the positioning accuracy in the indoor Bluetooth positioning networks. Experimental results show that the relative error of the proposed RSOA between the estimated results and the measured ones can reach as low as 0.2%, and the absolute errors can be reduced to 0.13 m at most within 10 m.

Analysis Of Quality Control Dengan Statistical Quality Control untuk Meminimalisir Produk Gagal Pada UD.Utun Kedung Supit Probolinggo

Pengendalian kualitas merupakan teknik manajemen produk dalam mengukur layak atau tidaknya produk atau jasa, setelah itu dilakukan perbandingan produk yang ada dengan produk pesaing dengan tujuan meperbaiki kekurangan yang ada agar mampu bersaing dengan produk yang sejenis. Quality control digunakan sebagai upaya untuk meminimalisir adanya produk gagal yang tidak bias dihindari dalam kegiatan operasional sehingga konsumen merasa puas dengan produk yang dipilihnya serta produsen bisa mencapi target output yang berkualitas sesuai dengan yang direncanakan. Tujuan pada penelitian ini difokuskan kepada upaya mimalisir produk gagal dengan metode statistic of quality control dengan alat analisis diagram kontrol. Berdasar hasil evaluasi terjadinya produk gagal pada UD.UTUN masih dalam kategori batas wajar dengan nilai rata-rata kerusakan sebesar 0.096 atau 9,6% dari total produk. Nilai pengendalian kualitas batas atas (UCL) 0,14 atau 14% dan (LCL) batas bawah -0,05 atau 0% karena LCL kurang dari 0.

Implementation of Educative Learning Media Counting Tree to Improve Student's Cognitive Abilities in Kartika Tanjung Morawa Kindergarten

Counting is a branch of mathematics which is a basic skill that children need to master from an early age. In fact, the ability to count in early childhood is still very low, this is because children find it difficult to count or pronounce a sequence of numbers, count by pointing at objects and pointing to a sequence of objects. On the other hand, teachers do not take advantage of the learning media used to support children's learning outcomes in arithmetic. To overcome this problem, learning to count is carried out using educational learning media Counting Tree because by utilizing educational learning media Counting Tree (counting tree) learning to count will be easier, interesting and fun for children.

Fuzzy Estimate of the Development of Passenger Cars Production in the Czech Republic

The global outbreak of the COVID-19 and the measures taken, disrupted fundamentally economies around the world. Almost all sectors were affected. The experts have long emphasised the Czech economy’s dependence on the automotive industry. Car producers and companies linked to them have been loaded by severe difficulties after the pandemic outbreak. The article shows one of the constructive ways how to forecast a change in the passenger cars production in the Czech Republic in 2020. Metodologically we lean on a procedure of the fuzzy approach. The prediction itself cannot be derived from the series of historical data of the variables that are related to the target output variable as shown in the fuzzy prediction of GDP for 2018 by this author. Due to the extreme situation caused by pandemic outbreak, the role of expert predictions come intensively into play with their outcomes becoming the set of input data to the fuzzy model. The result of the fuzzy forcast of a change in the cars production in CZ for 2020 shows a greater drop than the official statistical model claims.

PENGAYAAN PAKAN BENIH RAJUNGAN (Portunus Pelagicus) STADIA MEGALOPA MELALUI PEMBERIAN BETA KAROTEN

Penelitian ini bertujuan untuk meningkatkan nilai nutrisi pakan alami rotifer dan artemia melalui penambahan beta karoten yang bersumber dari wortel. Penelitian ini dilaksanakan pada bulan Mei 2020 di unit pembenihan kepiting dan rajungan Balai Pe-rikanan Budidaya Air Payau (BPBAP) Takalar. Rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL) sebanyak 4 perlakuan dan 3 ulangan. Hewan uji yang digunakan adalah larva rajungan (Portunus Pelagicus) stadia megalopa yang ditebar dengan kepadatan 5 ekor/l dan dipelihara sampai memasuki stadia crab. Luaran penelitian yang ditargetkan adalah teknologi pengayaan pakan alami rotifer dan artemia menggunakan beta karoten yang berasal dari wortel. Hasil penelitian menunjukkan bahwa Pemberian frekwensi pakan yang tepat setelah dikayakan dengan beta caroten akan meningkatkan sintasan dan pertumbuhan pada larva rajungan. Frekwensi pakan yang tepat diberikan pada larva rajungan yang terbaik untuk kelang-sungan hidup larva rajungan adalah pemberian pakan 3 kali/hari. This study aims to increase the nutritional value of natural rotifer and artemia feed by adding beta carotene from carrots. This research was conducted in May 2020 at the hatchery unit of the Brackish Water Cultivation Fishery Center (BPBAP) Takalar. The research design used was a completely randomized design (CRD) with 4 treatments and 3 replications. The experimental animals used were small crab larvae (Portunus pelagicus) in the megalopa stage which were stocked with a density of 5 individuals/l and they were kept until entering the crab stage. The target output of this research is natural feed enrichment technology for rotifer and artemia using beta carotene derived from carrots. The results showed that giving the right frequency of feed after being enriched with beta carotene would increase survival and growth in small crab larvae. The best frequency of feed given to small crab larvae for the survival of small crab larvae is feeding 3 times/day.

ANALISIS FULL COSTING PADA OUTPUT PROGRAM LAYANAN PENGELOLAAN PEMBIAYAAN TAHUN ANGGARAN 2018-2019

Penganggaran Berbasis Kinerja (PBK) merupakan suatu usaha untuk mengkaitkan antara kinerja yang dicapai dengan biaya yang dikeluarkan. Pembiayaan APBN merupakan program yang dilakukan oleh Direktorat Jenderal Pengelolaan Pembiayaan dan Risiko (DJPPR), Kementerian Keuangan. Dengan mengambil data rincian anggaran DJPPR seperti DIPA, KAK, dan RKAKL dapat dihitung berapa total biaya (full cost) yang diperlukan untuk pelaksanaan pembiayaan APBN. Di DJPPR output program terkait hal tersebut adalah Output Program Layanan Pengelolaan Pembiayaan. Pada penelitian ini akan dihitung full cost dari output program tersebut, dengan cara mengklasifikasikan biaya-biaya terkait ke dalam biaya langsung dan biaya tidak langsung. Kemudian biaya-biaya tersebut dialokasikan untuk memperoleh total cost (full cost) dari output program. Berdasarkan hasil penelitian ini diperoleh total cost (full cost) dari Output Program Layanan Pengelolaan Pembiayaan pada TA 2018 sebesar Rp71.449.847.389,00 dan TA 2019 sebesar Rp69.368.854.183,00. Berdasarkan perhitungan full cost tersebut, dapat diperoleh satuan biaya untuk setiap rupiah utang yang diperoleh. Hasilnya menunjukkan bahwa pada satuan biaya dari TA 2018 ke TA 2019 terdapat tren yang menurun sebesar negatif 14,82%. Selain itu, walau perkembangan utang yang meningkat tetapi DJPPR mampu menurunkan total biayanya. Hal ini menunjukkan bahwa DJPPR dapat mencapai target output dengan biaya yang efisien.
