Abstract

Analysis Determining The Cost Of Production Disco Beans at UD Kecak Mama The COVID-19 pandemic conditions, as well as the business's location, determine UD Kecak Mama business competitiveness. To keep this competition at bay, competitive pricing might be used. It will necessitate a more exact method. The purpose of this research is to determine the cost of production with the UD Kecak Mama method, the cost of production with the full costing method, and the difference between the two. The method used is full costing. According to the findings of the study, UD Kecak Mama's computation calculates the cost of production solely by varying the packing size, so that the results were Rp. 9.738,00 per pack of 200 gr and Rp. 19.475,00 per pack of 400 gr. The full costing method determines a unique production cost for each taste and packaging variations. The cost of production obtained ranges from Rp. 10.108,00 to 11.020,00 for per pack of 200 gr, and Rp. 20.216,00 to Rp. 22.040,00 for per pack of 400 gr. The difference between these two ways is that the production costs for each disco bean flavored variant quite far in all that different. As a result, the full costing method's cost of production is still lower than the selling price, and UD Kecak Mama should employ the full costing method for its cost of production because it has meticulously examined the costs.

Abstract

Analysis Uncertainty Production, Price and Income of Farming Citrus Siam in Kerta Village, Payangan District, Gianyar Regency. Farming citrus siam is main source of income for most farmers in Kerta Village. The purpose of this study is to determine the source the uncertainty of farming citrus siam, the magnitude of production uncertainty, price and income also how to mitigate these uncertainty. There are several sources of uncertainty faced by farmers including sources of social uncertainty, physical uncertainty and economic uncertainty. The magnitude of uncertainty farming citrus siam there are first, production uncertainty with standard deviation is 1.616,11 kg/ha/year, then the score of coefficient variation is 0.09 and production uncertainty lower limit value is 14.764,63. Second, price uncertainty with standard deviation is 42,38 then we get the score if coefficient variation is 0,01 and price uncertainty lower limit value is Rp4.847,84. Last, income uncertainty with standard deviation in amount of Rp7.413.000,13 /ha/year, coefficient variation score is 0.11 and income uncertainty lower limit value is Rp53.863.133,07 /ha/year. The conclusion that a biggest uncertainty in farming citrus siam is income uncertainty with a value of 0,11, second largest uncertainty is production uncertainty with a value of 0,09 and the smallest uncertainty in farming citrus siam is price with a value of 0,01. In an effort to mitigate existing uncertainty with strategies for handling uncertainty sources by make regular sales, learn past mistakes, provide maximum care for plants by pruning, spraying and fertilizing and finally borrowing capital from related financial institutions. With this, farmers are expected to mitigate uncertainty in order to increase the amount of production and income of farmers in Kerta Village, Payangan District, Gianyar Regency.

Abstract

Income Analysis of Broiler Breeders in Ringinrejo District, Kediri Regency A lot of broiler chicken farming businesses experience up and down. Breeders don't always get high profits. The purpose of this study is to analyze the quantity of income and to analyze the product factors that influence the quantity of product of broiler farms for partnership and independent patterns in Ringinrejo District, Kediri Regency. The research is conducted in Selodono and Sambi Village, Ringinrejo District, Kediri Regency, East Java Province. The types of data used are qualitative and quantitative data sourced from primary data and secondary data. The method of data collection is carried out by observation and interview. The results show that the partnership pattern receives lower income for each kg chicken than the independent pattern, which is Rp 1.068,00 while the independent pattern is Rp 3.099,00. Furthermore, the result of the analysis shows that the quantity of DOC and the quantity of feed partially have a positive and significant effect on the quantity of product, while the area of the cage has a negative and significant effect. The other variables partially have no significant effect on the quantity of product. The independent pattern of broiler farming is more profitable because income of the independent pattern is higher than the partnership pattern. Before starting production, breeders have to look at the market conditions to find out the purchase price and the selling price of livestock.

Abstract

Abstrak Getaran pada mesin biasanya tidak dapat dicegah atau dihindari. Getaran yang semakin besar dan tidak dimonitoring akan menyebabkan kemungkinan terjadinya kerusakan fatal pada mesin. Pada penelitian ini dilakukan perancangan sistem pengukuran getaran pada mesin menggunakan sensor piezoelektrik LDT0-028K. Dalam penggunaannya, sensor perlu dilakukan karakterisasi sebelum digunakan. Tujuan karakterisasi sensor piezoelektrik LDT0-028K yaitu untuk mengetahui keakuratan nilai frekuensi yang terukur oleh sensor. Dalam proses karakterisasi digunakan kalibrator sebagai penghasil getaran dengan frekuensi yang dapat dikontrol. Metode yang digunakan dalam mengkarakterisasi sensor piezoelektrik LDT0-028K yaitu dengan cara membandingkan hasil pengukuran sensor dengan alat standar Tachometer. Berdasarkan hasil uji coba, sensor piezoelektrik LDT0-028K memiliki kesalahan relatif pengukuran rata-rata sebesar 0,67% dan dapat bekerja dengan baik pada rentang frekuensi 13,53 Hz sampai dengan 59,57 Hz. Selanjutnya, sensor akan digunakan untuk pengembangan sistem pengukuran dan monitoring getaran pada mesin berbasis IoT (Internet of Things). Kata-kata kunci: sensor piezoelektrik, getaran mesin, monitoring mesin, karakterisasi sensor. Abstract Vibration in engines usually cannot be prevented or avoided. Vibrations that are getting bigger and not monitored will cause the possibility of fatal damage to the machine. In this research, a vibration measurement system was designed on a machine using a piezoelectric sensor LDT0-028K. In use, the sensor needs to be characterized before use. The purpose of characterizing the LDT0-028K piezoelectric sensor is to determine the accuracy of the frequency value measured by the sensor. In the characterization process, a calibrator is used as a vibration generator with controllable frequency. The method used in characterizing the LDT0-028K piezoelectric sensor is by comparing the measurement results of the sensor with a standard tachometer. Based on the test results, the LDT0-028K piezoelectric sensor has an average relative measurement error of 0.67% and can work well in the frequency range of 13.53 Hz to 59.57 Hz. Furthermore, the sensor will be used for the development of a vibration measurement and monitoring system on IoT (Internet of Things) based machines. Keywords: piezoelectric sensors, machine vibration, machine monitoring, sensor characterization.

Abstract

Subak sadap tiris merupakan subak yang sumber air irigasinya tidak langsung dari bendungan melainkan dari curah hujan dan subak hulu, sehingga ketersediaan air irigasi berfluktuasi. Penelitian ini untuk menganalisis tingkat resiko dan persepsi petani terhadap penyebab resiko produksi padi di subak sadap tiris yaitu Subak Temaga di Daerah Irigasi Kedewatan Bali. Pengumpulan data dilakukan melalui wawancara dengan menggunakan kuesioner kepada 30 petani yang dipilih secara acak dan FGD pada periode Juni hingga Agustus 2018. Risiko produksi dalam penelitian ini adalah hasil yang diharapkan tidak tercapai dan menyebabkan kerugian. Risiko produksi diukur berdasarkan koefisien variasi dan persepsi petani terhadap penyebab risiko dianalisis secara deskriptif dan kualitatif. Hasil analisis menunjukkan bahwa risiko produksi beras relatif rendah yaitu 16%. Persepsi petani terhadap penyebab resiko produksi padi termasuk dalam kategori sangat baik. Oleh karena itu, disarankan bagi petani untuk memitigasi risiko produksi padi antara lain dengan meningkatkan kualitas saluran irigasi, mencegah serangan organisme pengganggu tanaman bekerja sama dengan instansi terkait.
