Judul: Supply Chain Efficiency Analysis of Japanese Koi Fish (Cyprinus rubrofuscus) in PT. Solaris Koi Indonesia
Abstrak: Volume impor ikan koi ke Indonesia yang lebih tinggi dari volume ekspornya berimbas pada harga ikan yang berfluktuasi, sehingga perlu adanya informasi rantai pasok jenis dan grade ikan koi yang memberikan efisiensi tertinggi dengan risiko terendah. Penelitian ini bertujuan untuk menganalisis proses, jejaring, pelaku, efisiensi, dan peluang risiko yang terdapat pada rantai pasok ikan koi asal Jepang di PT. Solaris Koi Indonesia. Pengumpulan data dilakukan dengan pengamatan langsung dan wawancara dengan metode studi kasus. Analisis data menggunakan marjin pemasaran, farmer’s share, dan metode failure mode and effect analysis (FMEA). Proses produksi ikan koi di PT. Solaris Koi Indonesia sesuai dengan SNI 7734:2011 dan karantina ikan sesuai formulir Cara Karantina Ikan yang Baik (CKIB). Rantai pasok terdiri dari 20 saluran grade A, 7 saluran grade B, dan 4 saluran grade C yang dijalankan oleh pihak pembudidaya, dealer, dealer kropyokan, dan konsumen akhir. Aliran informasi mengalir secara dua arah, sedangkan aliran harga dan produk mengalir satu arah dari hulu ke hilir. Saluran A Shusui 2, A Asagi 2, dan A Showa 1 merupakan saluran paling efisien dengan tahapan yang pendek. Variabel risiko yang berkaitan dengan harga memberikan dampak tertinggi berdasarkan analisis FMEA., The volume of koi fish imports to Indonesia is higher than the volume of exports, resulting in fluctuating fish prices, so it is necessary to know the koi fish supply chains that provide the highest efficiency with the lowest risk. This study aims to analyze the processes, networks, actors, efficiency, and risk opportunities in the Japanese koi fish supply chain at PT Solaris Koi Indonesia. Data collection was carried out by direct observation and interviews with the case study method. Data analysis uses marketing margin, farmer's share, and failure mode and effect analysis (FMEA) method. The koi fish production process at PT Solaris Koi Indonesia is in accordance with SNI 7734:2011 and fish quarantine according to the CKIB form. The supply chain consists of 20 grade A channels, 7 grade B channels, and 4 grade C channels run by the farmer, dealers, kropyokan dealers, and end consumers. Information flow is bidirectional, while price and product flow are one-way from upstream to downstream. Channels A Shusui 2, A Asagi 2, and A Showa 1 are the most efficient channels with the shortest stages. Risk variables related to price have the highest impact based on FMEA analysis.

Judul: Analisis Efisiensi Faktor yang Mempengaruhi Produksi Ikan Koi di Kecamatan Cisaat Kabupaten Sukabumi
Abstrak: Koi fish (Cyprinus carpio) is a leading commodity of freshwater fish that attracted many people. Koi fish is not only kept by hobiis but also it’s interested and profitable commodity. Cisaat is one of producer of Koi fish that located in Northern Sukabumi, West Java, Indonesia. The turnover of Koi fish business in Cisaat can reach IDR 20 million per month. However, productions are still fluctuative and high quality products are still difficult to achieved, so the research study about the factors that influence Koi fish’s production is necessary to do. The purposes of this study are (1) to identify the factors that influence Koi fish’s production in Cisaat; (2) to analyze the efficiency level of the use of production factors of Koi fish in Cisaat; and (3) to identify consumer’s transaction motive to purchase koi fish in Cisaat. The production function model is analyzed by using multiple linear regeression analysis, production efficiency analysis are technically and economically, and consumer’s transaction motive to purchase Koi fish is analyzed by using descriptive analysis. The result of the research study showed that seed, manure, and medicines significantly affected Koi fish’s production. The use of these production factors has been achieved the efficiency technically but not economically yet. The main transaction motive to purchase Koi fish is because of its beauty on it’s body shape and colors with purchasing purpose is hobby.

Judul: Application of Mel Frequency Cepstrum Coefficients (MFCC) as Feature Extraction on Phoneme Recognition with Probabilistic Neural Network (PNN) as Classifier
Abstrak: Voice recognition (speech recognition) is one field of study in voice processing. This technology can convert voice signals into a form of written information (text). With this technology, people can interact with a computer. MFCC feature extraction computes the cepstral coefficients by considering the human hearing. This research is a phoneme recognition using feature extraction MFCC and PNN as feature matching model. This study compares the coefficient, overlap, and the test data without noise and with noise. MFCC is used with 13, 20, 26 coefficients and 0%, 25%, 50% overlap. Noise is added by 30 dB, 20 dB and 10 dB. From the comparison of the three overlaps, produced the best accuracy at 50% overlap with an accuracy of 94,71%. From comparing the three coefficients, better accuracy resulting in coefficients of 20 and 26 with an accuracy of 97,12% at 50% overlap. After comparing between the coefficients of 20 and 26 with overlap of 25% then the coefficient 26 is obtained that better accuracy of 94,23%. This shows that in this study the coefficient 26 is the best. In this research, there are three noise variables. The variables are 10 dB, 20 dB, and 30 dB. The best accuracy reached when the noise variable is 30 dB rather than 10 dB or 20 dB because the accuracy has the closest accuracy compared by the accuracy when noise was not added into the data. When the noise variable is 30 dB, the percentage of accuracy is 85,3%.
