Analisis Algoritma K-Medoids pada Sistem Klasterisasi Produksi Perikanan Tangkap Kabupaten Aceh Utara
Get PDFBelum adanya sistem pengelolaan data produksi perikanan tangkap di Kabupaten Aceh Utara menyebabkan pemerintah Kabupaten Aceh Utara kesulitan dalam mengklasterisasi data produksi perikanan tangkap. Penelitian ini bertujuan untuk menerapkan algoritma k-medoids dalam sistem klasterisasi data produksi perikanan tangkap berbasis web menjadi tiga klaster. Penelitian ini menggunakan data produksi perikanan tangkap di Kabupaten Aceh Utara tahun 2019-2020 yang diperoleh dari Dinas Kelautan dan Perikanan Kabupaten Aceh Utara. Hasil penelitian dengan 10 kali pengujian menunjukkan bahwa nilai rata-rata iterasi k-medoids sebesar 2,5 dengan jumlah iterasi terbanyak 4 iterasi dan iterasi terkecil senilai 2 iterasi. Hasil cluster data produksi perikanan tangkap dengan jenis tangkapan ikan Albakora masuk kedalam potensi produksi tangkapan klaster sedang. Jenis tangkapan ikan Alu-alu, Tongkol Krai, Tuna Mata Besar, Tuna Sirip Biru Selatan masuk kedalam cluster rendah. Jenis tangkapan ikan Banyar, Bawal Hitam dan Bawal Putih masuk kedalam klaster tinggi. Adapun hasil klaster yang terbentuk dapat membantu pemerintah Kabupaten Aceh Utara dalam mengambil kebijakan untuk menambah nilai produksi tangkapan ikan di Kabupaten Aceh Utara
Impact of Heated, Acidified Volcanic Ash and Manures on Properties of Marginal Soil and Growth of Soybean
Get PDFBackground: The nutrients released from volcanic ash and manures can enhance soil fertility and plant growth. Weathering of minerals in volcanic ash depends on water, temperature and acids. This study aims to examine the influence of heated and acidified volcanic ash and their combination with manures on pH and nutrient levels of marginal soil and soybean growth.
Methods: The study was designed using a factorial Randomized Block Design, consisted of two factors with three replications. The first factor was heated and acidified volcanic ash (VA) and the second factor was cow manures (CM) which consist of three levels.
Result: The results showed that various of VA treatment, as well as its combination with CM on marginal soils exhibited acidic soil pH, Total-N, exchangeable-K, -Ca were low, while available P and exchangeable-Mg were classified moderate. Various treatments of VA and their combination with CM did not significantly interact on all parameters, except some parameters of soybean. Application of VA and CM on marginal soil interacted significantly on plant height and weight of 100 grains only

Determinants of Oil Palm Farmers’ Welfare in Aceh, Indonesia
Get PDFThis study examines the determinants of the welfare of oil palm farmers in Aceh, Indonesia. The main focus of this study is on the current price of oil palm, whether it
affects the level of welfare of oil palm farmers or not and what efforts the government has made to improve the farmers’ welfare. This research applies quantitative descriptive
approach. The number of samples was 70 Aceh farmers in 24 districts in east Aceh. The selected famers who have been designated as farm owners and workers. The sampling
technique used is judgment sampling. The research data collected by using a closed questionnaire. The results of the study found that when the price of palm oil is unstable,
farmers must be able to process by-products in an effort to maintain the welfare of their families. In testing the two models, the same results were obtained, this cost could not be controlled by the farmers, especially the maintenance costs using industrial processed products such as fertilizers and pesticides. Therefore, the government must further intensify the economic empowerment programs for oil palm farmers. More programs for people are still required. During the Pandemic Covid-19, farmers only relies on the sale of fresh fruit bunches (FFB) at fluctuating prices which decreases farmers' income thus making them unable to improve their welfare.
