Abstract

AbstractThe potential of Java Ijen-Raung Arabica Coffee in the Bondowoso Regency, East Java needs to be increased by developing the downstream agroindustry. This study aims to determine the location of the downstream coffee agroindustry development area and its potential products, determine the added value of downstream coffee products, analyze its financial feasibility, and formulate a development strategy. Research methods used in this study include factor weighting, exponential comparison method, interpretive structural modeling, Hayami method, and financial feasibility analysis. The results showed that the development of the Java Ijen-Raung Arabica Coffee agroindustry was prioritized in Sumberwringin District as a development center. Downstream coffee products that have the potential to be developed are ground coffee. The added value generated from the processing of ground coffee is IDR 9,320/kg, with a value-added ratio of 48.09%. The results of the financial feasibility analysis show that the downstream coffee agroindustry is financially feasible to be developed by business actors. The downstream agroindustry development strategy formulation for Java Ijen-Raung Arabica Coffee refers to the key development sub-elements, i.e. increasing market area, monitoring product quality, and involving stakeholders in its implementation.Keywords: Bondowoso Regency, downstream agroindustry, Java Ijen-Raung Arabica Coffee, strategy AbstrakPotensi Kopi Arabika Java Ijen-Raung di Kabupaten Bondowoso, Jawa Timur perlu ditingkatkan melalui pengembangan agroindustri hilir.

Abstract

AbstractPerusahaan Daerah Perkebeunan (PDP) Kahyangan Jember in East Java is a regional company owned by The Jember Regency Government that is engaged in the plantation business. PDP Kahyangan Jember implements supply chain management in its business, however there are still some problems in its implementation and management. Some of the issues are the quantity of ground coffee production that does not meet the targeted quantity, decreased coffee beans quality, and reduced coffee yields. These problems can be reduced using a risk management approach. This study aimed to identify the activities of the ground coffee supply chain in PDP Kahyangan Jember and its risks, to determine the level of the risks, and to develop a risk management strategy for PDP Kahyangan Jember ground coffee supply chain. This study used the House of Risk (HOR) method which consists of two phases, i.e. HOR 1 and HOR 2. HOR 1 is used to identify risks in the supply chain. HOR 2 is used to develop a strategy for handling these risks. The HOR 1 analysis results show there are 28 risk events and 33 risk sources, with 15 priority risk sources being considered in the risk management strategies preparation. The results of HOR 2 analysis show eight priority management strategies that can be implemented by PDP Kahyangan Jember.Keywords: House of Risk, risk management, supply chain AbstrakPerusahaan Daerah Perkebunan (PDP) Kahyangan Jember di Jawa Timur adalah perusahaan daerah milik Kabupaten Jember yang bergerak pada bidang usaha perkebunan. PDP Kahyangan Jember menerapkan manajemen rantai pasok pada bisnisnya, namun dalam penerapan dan pengelolaannya masih terdapat beberapa permasalahan. Permasalahan tersebut antara lain adalah jumlah produksi kopi bubuk tidak sesuai target perencanaan produksi, penurunan kualitas biji kopi, dan hasil panen kopi yang menurun. Pendekatan manajemen resiko dapat digunakan untuk mengurangi permasalahan tersebut. Tujuan penelitian ini adalah mengidentifikasi aktivitas rantai pasok kopi bubuk di PDPD Kahyangan Jember dan risikonya, menentukan tingkat risiko, dan menyusun strategi penanganan risiko pada rantai pasok kopi bubuk di PDP Kahyangan Jember. Metode yang digunakan pada penelitian ini adalah House of Risk (HOR) yang terdiri dari dua fase, yaitu HOR1 dan HOR 2. HOR 1 digunakan untuk mengidentifikasi risiko pada rantai pasok. HOR 2 digunakan untuk menyusun strategi penanganan risiko tersebut. Hasil analisis HOR 1 menunjukkan bahwa terdapat 28 kejadian risiko dan 33 agen risiko dengan 15 agen risiko prioritas yang dipertimbangkan dalam penyusunan strategi penanganan risiko. Hasil analisis HOR 2 menunjukkan bahwa terdapat 8 strategi penanganan prioritas yang dapat diimplementasikan oleh PDP Kahyangan Jember.Kata kunci: House of Risk, manajemen risiko, rantai pasok

Abstract

AbstrakPT XYZ adalah salah satu produsen pakan unggas di Kabupaten Banyuwangi, Jawa Timur. Permasalahan dalam pengembangan pakan unggas di PT XYZ adalah harga pakan unggas yang berfluktuasi. Komponen terbesar bahan baku pembuatan pakan unggas adalah jagung dan bungkil kacang kedelai (BKK). Permasalahan fluktuasi harga pakan unggas dapat diatasi dengan prakiraan harga jagung dan BKK. Prakiraan yang tepat dapat membantu PT XYZ untuk optimalisasi alokasi sumber daya perusahaan. Optimalisasi sumber daya bertujuan untuk meningkatkan keuntungan yang diperoleh perusahaan. Tujuan dari penelitian ini adalah pengembangan model jaringan syaraf tiruan (JST) backpropagation untuk prakiraan harga jagung dan BKK. Model JST dikembangkan dengan perlakuan jumlah lapisan tersembunyi (node hidden layer), fungsi aktivasi, dan laju pembelajaran (learning rate). Data penelitian yang digunakan adalah harga jagung dan BKK pada periode Januari 2016-Oktober 2018. Hasil penelitian menunjukkan bahwa model JST terbaik untuk prakiraan harga jagung adalah 12 node input, 5 node hidden layer, dan 1 node output dengan kombinasi fungsi aktivasi sigmoid biner (logsig)-sigmoid biner (logsig) dan learning rate 0,005. Model JST terbaik untuk prakiraan harga BKK adalah 12 node input, 10 node hidden layer, dan 1 node output dengan kombinasi fungsi aktivasi sigmoid bipolar (tansig)-pure linier (purelin) dan tingkat learning rate 0,006.Kata kunci: harga jagung dan bungkil kacang kedelai, Jaringan Syaraf Tiruan, pakan unggas AbstractPT XYZ is one of the poultry feed producers in Banyuwangi Regency. The problem in developing poultry feed at PT XYZ was related to the fluctuative price of poultry feed itself. The biggest component of raw material for producing poultry feed that affect prices were maize and soybean meal. The problem of poultry feed price fluctuations can be overcome by forecasting the price of maize and soybean meal. The accurate forecast can be used as a reference for PT XYZ in optimizing the allocation of resources so as to increase the profits of the company. The aim of this study was developing a backpropagation neural network (ANN) model. The ANN model was developed by number of hidden layers, activation function, and learning rate. The price of maize and soybean meal in the period January 2016-October 2018 was used as data in this study. The best model for forecasting maize price was 12 input nodes, 5 hidden layer nodes, and 1 output node with a combination of the sigmoid binary (logsig)-sigmoid binary (logsig) activation function and 0.005 learning rate. The best model for forecasting soybean meal was 12 input nodes, 10 hidden layer nodes, and 1 output node with a combination of sigmoid bipolar (tansig)-pure linear activation function (purelin) and 0.006 learning rate.Keywords: Artificial Neural Network, maize and soybean meal prize, poultry feed

Abstract

The potential for pollution of rivers is influenced by river-water discharge and the distribution of pollution sources. This research aimed to examine recommendations for water quality management in the Bedadung River segment of the Patrang, Sumbersari, and Kaliwates Districts as an urban area of Jember Regency refer to simulations of the total pollution load capacity for 10 years (2016-2026) using a system dynamics modeling. The preparation of a system dynamics modeling used Powersim 5.0 software. It could represent holistic environmental management modeling. The input data were total suspended solid (TSS), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and the streamflow of the Bedadung River. The model scenarios were the business of usual, moderate, and optimistic scenarios involving environmental and socio-economic aspects. The medium-term and long-term recommendations for water quality management of the Bedadung River based on system dynamics simulation were respectively moderate scenario and optimistic scenario. The strategies of the moderate scenario were application of the best management practice method in agricultural cultivation, improving sanitation and domestic wastewater treatment, implementing clean production in the field of livestock and industry, as well as waste management on riverbanks. These alternative strategies for river water quality management can be used as consideration for protecting surface water sources in urban areas.
