Abstract

This study aimed to evaluate the role of broiler feed standards using the Analytic Network Processing (ANP) method. Data were taken from five feed manufacturing companies, three feed experts and three government institutions in the feed sector. There were 3 criteria and 6 sub-criteria in determining the best alternatif out of 6 feed evaluation in the context of implementing broiler feed quality and safety standards. The results showed that the greatest sub-criteria weight was effectiveness (0.750). In addition, the selected alternatif analysis with the highest weight was proximate analysis (0.315; 0.280) in the assessment by feed companies and the government and followed by amino acids analysis (0.365) in the assessment by feed experts. From the results, all entities assessed the proximate analysis as a priority because proximate testing on animal feed could help to determine the nutritional quality of feed by knowing the content of protein, fat, crude fiber, and other nutrients in the feed. This study was concluded that proximate testing was very important in the animal feed industry because it could help in determining the nutritional quality of animal feed, optimizing livestock growth and production, preventing nutritional deficiencies in livestock, determining the selling price of feed, and guaranteeing feed quality. Key words: ANP, feed quality and safety testing, feed standards, quality control and feed safety

Abstract

This study aimed to evaluate separation method to reduce the shells of palm kernel cake (PKC) and to optimize the extrusion process to increase the nutrient utilization. The sieving process was a method of separating two materials that had different sizes, both solid and liquid materials. The extrusion process variables used in this study were extrusion temperature and moisture content of PKC as optimization variables in the response surface methodology (RSM). The RSM design was central composite design (CCD) with 13 treatments and analysed with Design Expert version 13. PKC was separated from its shell by filtering it at a size of ≤0.600 mm and continued the extrusion process for 13 treatments using temperatures starting from 72 to 128 °C and moisture content starting from 22 to 78%. The main variable response was crude protein (CP), crude fibre (CF), and ether extract (EE). Based on statistical analysis, it was found that temperature and moisture content had a significant effect (p<0.05) on the mathematical model of the relationship between the independent variables (temperature and moisture content) and the best CP, CF and EE responses. PKC extrudate had a bulk density value of 420 kg m-3 and a total solubility of 24.11%. The conclusion of this study was that the optimal extrusion treatment at BIS was using 91 °C and 42% moisture content to produce the best chemical and physical qualities.

Abstract

As a corn substitute, cassamore (Cassava – Moringa Mix) is an innovative local feed ingredient based on cassava with a mixture of palm kernel meal, cassava leaf flour and moringa extract processed by extrusion that can destroy antinutrients, improve nutrient content and digestibility. This study aimed to optimize the temperature and water content of the hydrothermal extrusion process, as well as to analyze the effect of extrusion on the physical and chemical characteristics of Cassamore as a corn substitution. The method used is response surface methodology in the statistical application of design expert 13 with extrusion temperature factors of 100, 110, 120 (oC) and moisture content of 16, 18, 20 (%). Further research was carried out for the physical and chemical properties of Cassamore using a complete randomized design (CRD). The results showed that the water absorption index value is significant (p<0.05) with the optimal value located at 100 °C and 20% moisture content, while the water solubility index value is not significant. The values of bulk density, tapped density, and angle of repose on Cassamore after being extruded were smaller than those before being extruded. The bulk density and tapped density values for Cassamore were below corn, while Cassamore's angle of respose was above the corn. Cassamore's specific gravity value after extruding under corn. Chemical properties (Ash, crude protein, crude fat, crude fiber) decreased after extrusion, but NFE increased after extrusion. It is concluded that Cassamore has a potency to replace corn.

Abstract

This study aims to evaluate the production performance of Micro, Small, and Medium Enterprises (MSMEs) in rengginang production using the Quality Function Deployment (QFD) approach. Rengginang is a traditional Indonesian snack made from sticky rice, which has economic and cultural value but faces challenges in production consistency, hygiene, and capacity due to manual processing methods. The QFD method was applied to translate six key customer needs—such as production speed, hygiene, capacity, consistency, quality control, and product variation flexibility—into technical characteristics through the House of Quality (HoQ) matrix. Results showed that the most critical production need was achieving a drying process of no more than one day, followed by hygienic handling. These were translated into technical priorities such as high-speed drying machines and closed-drying systems. The relative weight analysis indicated that these technical improvements had a high impact on production performance with relatively moderate implementation complexity. This study provides MSME actors with a structured model to improve production efficiency and competitiveness based on customer-oriented planning. Keywords: Quality Function Deployment (QFD), House of Quality, MSMEs, Rengginang, Production Performance

Abstract

Palm kernel cake (PKC) is a year-round by-product of the palm oil industry that is affordable and rich in protein nutrients. However, the main obstacle to utilizing PKC is its high shell fraction, which results in high crude fiber content and low nutrient digestibility in poultry. This study aimed to evaluate the in vitro digestibility of PKC processed through separation and extrusion methods as poultry feed ingredients. There were three treatments with four replicates, namely P1 (untreated PKC), P2 (sifted PKC), and P3 (PKC resulting from a combination of sifting and extrusion). The results showed that the treatments had a significant effect (p<0.05) on nutrient digestibility. The sieving treatment resulted in higher crude protein digestibility compared to the other two treatments, while the combination of sieving and extrusion increased crude fiber digestibility but was not significantly different from the sieving treatment. Processing PKC through screening or a combination of screening and extrusion can increase crude protein and crude fiber digestibility in vitro. However, the highest crude protein digestibility was obtained in the screening treatment.

Abstract

Abstract  Perusahaan yang memiliki keinginan untuk memenangkan persaingan yang terus meningkat di era globalisasi, perlu terus menerus melakukan perbaikan metode pengendalian persediaan suku cadangnya. Metode existing di perusahaan memiliki beberapa kekurangan seperti belum mempertimbangkan standar deviasi demand dan service level yang dikehendaki oleh perusahaan. Tujuan kajian ini adalah melakukan perbaikan pengelolaan persediaan suku cadang dengan menerapkan model yang memiliki karakteristik pengadaan yang sesuai dengan perusahaan. Model Fixed Time Period (FTP) adalah model yang sesuai karena telah memenuhi karakteristik pengelolaan persediaan di perusahaan seperti pemesanan barang dengan interval waktu yang konstan dan demand yang berfluktuatif. Hasil menunjukkan bahwa jumlah pemesanan pada suku cadang bandsaw dengan menggunakan metode existing perusahaan di tahun 2018 selalu lebih tinggi quantity ordernya dibandingkan dengan menggunakan metode FTP. Berbeda dengan suku cadang bandsaw, suku cadang thermoc, jumlah order dengan metode FTP tidak selalu lebih rendah; bahkan metode FTP seringkali lebih tinggi atau pun sama quantity ordernya pada tahun 2018.  Kata Kunci: Analisis ABC, Metode Fixed Time Period, Manajemen Inventori The company that has the desire to winning the increasing competition in the era of globalization need to improve the method of spare parts inventory control continually. Existing approaches in companies have several disadvantages such as not considering the standard deviation of demand and service level desired by the company. The purpose of this study is to improve the management of spare parts inventories by implementing a model that have right characteristics that are in line with the company. The Fixed Time Period (FTP) model is an appropriate model because it has fulfilled the characteristic of inventory management in companies such as ordering goods with constant time intervals and fluctuating demand. The results show that the number of orders on bandsaw parts using the existing company method in 2018 always has a higher order quantity than using the FTP method. Unlike bandsaw parts, thermoc parts, the number is not still lower; even the FTP method was often higher or equal to the order quantity in 2018. Keywords: ABC Analysis, Fixed Time Period Methods, Inventory Management
