This research was conducted to identify all influencing factors of wheat flour demand of industries, which used wheat flour as main raw material. Samples of this research were five noodle industries and ten sweet cake industries in Yogyakarta municipality. Dependent variable influencing to wheat flour demand of small scale industries were price of wheat flour, price of substitutes (rice flour and tapioca starch), industry's income, and governmental regulation for wheat flour distribution. A double regression method was used to determine the roles of each dependent variable. Result of data analysis showed, that the wheat flour demand was influenced by five factors in following equation: ... If the price of wheat flour (Pt) increased at 1%, the demand of it (Qt) decreased at 0.09%. The increase in price of rice flour (Ptb) 1% caused the increase in demand of wheat flour (Qt) for 0.124%; The increase in price of tapioca starch (Ptp) for 1% affected the increase in demand of wheat flour 0.028%; the increase of wheat flour demand of 0.427; also for cake industry increase in its income 1% caused increase in the wheat flour was stopped, the demand of wheat flour decreased. This regulation affected the declination of wheat flour demand in small-scale industry of wheat demand for 0.036.

agriTECH Vol 19, No 1 (1999)
Publisher : Faculty of Agricultural Technology, Universitas Gadjah Mada, Yogyakarta, Indonesia

Karl Fischer Titration (KFT) is a well established and effective direct primary method to determine water content in various materials. It is based on a specific chemical reaction and it differs principally from the drying and distillation methods. The KFT was introduced as an alternative method to determine the water content in some Indonesian spices (clove, coriander, ginger and white pepper), which generally contain appreciable amount of volatile compounds to distract accurate moisture. The samples used were prepared by cutting and grinding with a morser. The KFT system used was one-component reagent with methanol as working medium. The samples were introduced into a KFT titration cell and titrated directly with the KFT reagent. The extraction time of determination was 60 seconds. The determination of the water content took approximately 10-20 minutes. The distillation and drying method served as control or reference method. The distillation methods which used was a mixture of toluene and xylene 95:5 (vlv) took 2 hours. The drying method was conducted at temperature of 105°C for 3-4 hours.

This article aims to investigate the accommodation of stakeholders’ voices and it’s challenges in the practices of curriculum development. Using a qualitative approach, the primary data was gathered through in-depth interviews with the head and secretary, and the administrative staff of four Study Programs in The School of Post Graduate Program of one of the leading universities in Yogyakarta, Indonesia. Whereas, secondary data was taken from the documents of curriculum reviews and accreditation documents. The research found that amidst the complexity of involving stake holder’s views within curriculum design, all the four programs have gathered the stake holders’ voices via tracer study, informal discussion during academic meetings and evaluation from the students. The accommodation of stake holders’ voices can be traced in the form of the addition of elective courses, merging of some courses, addition or omission of certain courses in the current curriculum design. However, the practice of curriculum development was challenged by various aspects such as the commitment of Study Programs to maintain their ‘scientific core’ vis a vis addressing market demand given their commitment to improve theories and knowledge, and the limitation of human resource availabilityArtikel ini Betjeman untuk meneliti akomodasi terhadap masukan stakeholder serta tantangannya dalam praktik pengembangan kurikulum. Menggunakan pendekatan kualitatif, data primer dikumpulkan melalui wawancara dengan ketua dan sekretaris, dan staf administrasi pada empat program studi di Program Pascasarjana di salah satu universitas terkemuka di Yogyakarta, Indonesia. Sementara itu, data sekunder diambil dari dokumen review kurikulum dan akreditasi. Penelitian ini menemukan bahwa di tengah kompleksitas pelibatan stake holder dalam desain kurikulum, keempat Program Studi mengumpulkan masukan stakeholder melalui tracer study, diskusi informal dalam pertemuan-pertemuan akademik dan evaluasi dari mahasiswa. Akomodasi yang dilakukan Program Study dapat dilacak dalam bentuk penambahan mata kuliah tambahan, penggabungan beberapa mata kuliah, penambahan atau pengurangan mata kuliah tertentu dalam desain kurikulum yang baru. Akan tetapi, pelaksanaan pengembangan kurikulum tersebut menghadapi tantangan berupa komitmen Program Studi untuk mempertahankan ‘inti keilmuan’ dihadapkan dengan bagaimana mengakomodir tuntutan pasar mengingat bahwa Program Studi memiliki komitmen untuk pengembangan teori dan pengetahuan, dan keterbatasan sumber daya manusia di Program Studi.

Indonesian local chicken has some advantages in compared with broiler chicken. Local chicken can live freely and sometimes serves as "saving" for family in villages. The local chicken is used as raw material for some traditional. This research focused on chemical and microbiological properties on local chicken carcasses and also their finished products, such as satay or fried chicken. Results of this research showed, that local chicken carcasses has more protein content than broiler carcasses, and has also lower calorie and fat content. But their fat and calorie became higher, after their fresh local chicken carcasses were prepared, spiced and fried or grilled ready-to-eat foods. All of fresh local chicken carcasses, which were taken and collected from local slaughtering houses, were contaminated by pathogenic microbes, such as Escherichia coli, Salmonella sp and Staphylococcus sp. But after processing of the fresh carcasses, the number of the pathogenic microbes decreased drastically, so food poisoning or out break of consumers was rarely occurred. The result's of evaluation on gender and socio-economic factors suggested, that local slaughtering house operations were feasible with no possibility to expand their activities. More investment to buy an electrical machine (Feather-Pluckier) was very useful for raising their productivity, capacity and ease in preparing carcasses. The women workers had three job description (owner, main worker and an assistant) in this slaughtering process, and they did not have difficulties to do their job and their loan actually was used to help their own economic family

Coffee consumption in Indonesia has increased significantly with the increase in coffee shops. According to data obtained from the data books in 2020, coffee consumption has increased by nearly 400,000 tons. The increasing number of coffee shops in Indonesia, particularly the Sleman Regency is due to the pandemic and changes in consumer behavior. Therefore, the purpose of this research was to determine the impact of consumer behavior on the purchasing decisions at Coffee Shops based on the personal, social, psychological, and cultural factors as well as the marketing mix and its improvement during the pandemic. In this research, 10 local coffee shops in the Sleman regency were used and consumers between the ages of 17 and 27 years who had purchased coffee drink products and made transactions in the past six months were selected. The respondents comprised 157 people, and the analysis was carried out using two methods: Partial Least Square Structural Equation Modelling (PLS-SEM) and Importance Performance Analysis (IPA). PLS-SEM was used to analyze the relationship between consumer behavior factors and purchasing decisions while the IPA method was used to analyze the most effective marketing mix during the pandemic. According to the result, the factors that influence the decision to purchase coffee are the psychological factors and marketing mix while personal, cultural, and social factors had no significant effect on the coffee purchasing decisions during the pandemic. Consequently, the marketing mix that needs to be focused on is price adjustment on the drink purchased.
