Abstract

This study aims to determine the combination dose of N, P, K and biological fertilizers on the growth and yield of red onion in alluvial soils. This research was conducted in the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak, which took place on April 19, 2019 until June 23, 2019. The method used was a Completely Randomized Design (CRD) consisting of 5 treatments, 5 replications, and 4 sample plants. Giving a combination of N, P, K and biological fertilizer that is A1 100% N, P, K + 0% biological, A2 75% N, P, K + 25% biological, A3 50% N, P, K + 50% biological , A4 25% N, P, K + 75% biological, A5 0% N, P, K + 100% biological. Observations made were the number of leaves, plant height, number of tubers, fresh weight of tubers, and dry weight of tubers. The results showed that the combination of N, P, K and biological fertilizers significantly affected the variable number of leaves, plant height, fresh weight of tubers and dry weight of tubers but had no significant effect on the observed variables of number of tubers. Based on the results during the study it can be concluded that the administration of a combination of 50% N, P, K fertilizer and 50% biological fertilizer is a more effective dose than other doses for growth and yield of shallots in alluvial soils. Keywords : Red Onion, NPK Fertilizer, Biofertilizer, Alluvial.

Market Basket Analysis is a rule that determines associations between various attributes and is a key application in the retail industry. This method is use to analyze past consumer purchasing behavior to determine items that are frequently purchase together. Its purpose is to uncover relationships between products purchased by customers in a single transaction. On the other hand, Frequent Pattern Growth is an alternative algorithm use to identify the most frequently occurring datasets within a collection of data. The testing results of 435 transactional data points from NTN Racing Store, using 1% minimum support value and 25% minimum confidence value, resulting four association rules within lift ratios above 1 which indicates significant relationships among itemsets. From these evaluation results, customer purchasing patterns can be identifying trough the association analysis rules. This information can assist the store owner in determining bundling packages to sell and to devise store sales strategies.

Abstract

Penelitian ini bertujuan untuk mengetahui perkembangan trend produksi dan konsumsi jagung pipilan di Indonesia dari tahun 1993-2018 serta mengetahui estimasi trend produksi dan konsumsi jagung pipilan di Indonesia dari tahun 2019-2023. Data yang digunakan dalam penelitian adalah data sekunder yang diperoleh dari BPS Indonesia dan Pusat Data Informasi Pertanian. Hasil analisis trend produksi dan konsumsi menunjukkan produksi jagung pipilan di Indonesia dari tahun 1993-2018 diketahui produksi mengalami peningkatan dengan rata-rata pertumbuhan sebesar 6,82%, konsumsi juga mengalami peningkatan dengan rata-rata pertumbuhan sebesar 5,68%. Analisis estimasi produksi dan konsumsi jagung pipilan di Indonesia tahun 2019-2023 berdasarkan program Minitab 18 didapatkan model trend yang tepat untuk estimasi produksi adalah model trend S-Curve dengan persentase penyimpangan atau MAPE 7,59% dan estimasi konsumsi adalah model trend Kuadratik dengan persentase penyimpangan atau MAPE 6,66%, dua model trend produksi dan konsumsi tersebut diambil karena persentase penyimpangan lebih kecil dibanding masing-masing model lainnya. Hasil estimasi produksi akan mengalami kenaikan rata-rata sebesar 9,29% pertahun dan konsumsi mengalami kenaikan rata-rata sebesar 4,38% per tahun. This study aims to determine the development of shelled corn production and consumption trends in Indonesia from 1993-2018 and to determine the estimated production and consumption trends of shelled maize in Indonesia from 2019-2023. The data used in this research is secondary data obtained from the Indonesian Central Bureau of Statistics and the Center for Agricultural Information Data. The results of the analysis of production and consumption trends show that the production of shelled maize in Indonesia from 1993-2018 shows that production has increased with an average growth of 6.82%, consumption also has an increase with an average growth of 5.68%.

The results of the estimated production will increase by an average of 9.29% per year and consumption will increase by an average of 4.38% per year
