Production of tuna in Sabang on the last two years has decreased significantly. In 2015, for example, the number of tuna production was 6,124 tons per week, while in 2017 it fell to 5,200 tons per week, or decreased by around 15 percent. This study aimed to analyze the amount of biomass, catch, and effort of tuna in sustainable conditions in Sabang using a quantitative method and 11 years (2006-2016) time-series data. The data consisted of catches and inputs from each fishing gear per year during the observation period. The data were analyzed by the surplus production model that was processed using Excel and Shazam. The results showed that the sustainable and actual production function models of tuna in Sabang had trajectories with patterns that continued to increase during the observation period. The current level of production over the past few years has exceeded sustainable production, and if this condition continues, it is feared there will be overfishing and overcapacity.
Ascorbic acid and calcitriol were frequently utilized in conjunction as therapy during the COVID-19 pandemic, and individuals with minor symptoms had notable improvements. There have been a few studies, often with conflicting findings, that examine the use of them for endothelium restoration and numerous clinical trial studies that failed to establish the efficacy. The aim of this study was to find the efficacy of ascorbic acid compared to calcitriol on the inflammatory markers monocyte chemoattractant protein-1 (MCP-1), nitric oxide (NO), and superoxide dismutase (SOD), as protective agents which play an important role in the early stages of atherosclerosis formation. This study was an experimental in vivo study. Methods: The total of 24 male Rattus norvegicus strain Wistar rats were divided into 4 groups, namely: control/normal group (N), atherosclerosis group (DL) given atherogenic diet, atherosclerosis group given atherogenic diet and ascorbic acid (DLC), and atherosclerosis group given atherogenic diet and calcitriol (DLD) treatment for 30 days. Results: Ascorbic acid and calcitriol treatment was significantly effective (P<0.05) in lowering expression of MCP-1 and increasing NO and SOD level. Calcitriol was superior to ascorbic acid in increasing SOD (P<0.05). There was no significant difference between ascorbic acid and calcitriol in decreasing MCP-1 and increasing NO (P>0.05). Discussion: Both treatments could reduce MCP-1, and increase NO and SOD by increasing antioxidants. In this study calcitriol was superior to ascorbic acid in increasing SOD, but not NO and decreasing MCP-1. According to the theory, it was found that calcitriol through nuclear factor erythroid 2-related factor 2 (Nrf2) causes a direct increase in the amount of SOD. Nrf2 is an emerging regulator of cellular resistance to oxidants. Conclusion: Ascorbic acid and calcitriol treatment was able to reduce MCP-1 and increase NO and SOD in atherosclerosis rat. Calcitriol was significantly superior in increasing SOD levels compared to ascorbic acid.
The program of“Asuransi Usaha Tani Padi” (AUTP) (Rice Farming Insurance) is the government’s program aims to protect the farmers from any harm caused by crop failure influenced by natural disaster such as flood, drought and pest attack. The AUTP program in Aceh was held since 2015, but the implementation expected was far from target determined. This research purposed to find out the participation range of farmers in AUTP program and several factor which influenced the achievement of AUTP Program. The research location was in Aceh Besar District and taking samples in 6 Sub-districts consist of Suka Makmur, Kuta Cot Glie, Seulimum, Indrapuri, Lhoong and Montasik. The respondents was 94 persons were chosen by purposive sampling. The data used in this research were primary and secondary data. Primary data were taken from interview and questionaire. The research variables of this study were farmers participation on some stage as proses, result enjoyment and evaluation of several factors from reapondents such as age, education, land area, income, program advantages and government support. The data analysis used were scoring and regresi logit analysis. The result of the analysis sais that the farmers participation on stage of proccess and evaluation were categorized medium while on the stage of result enjoyment was categorized high. The government support on the achievement of AUTP was higer than other factors
Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi produksi usahatani kangkung di kecamatan Darussalam kecamatan aceh besar. Penelitian ini dilaksanakan pada bulan Oktober dan November tahun 2021. Data yang digunakan dalam penelitian ini adalah data primer dan data sekunder. Data primer diperoleh dari wawancara langsung dan penyebaran kuisioner kepada petani kangkung di Kecamatan Darussalam Kabupaten Aceh Besar. Data sekunder dikumpulkan dan diperoleh dari Badan Pusat Statistik dan instansi lainnya. Metode pengambilan sampel dilaksanakan dengan menggunakan metode sensus dengan mengambil seluruh populasi petani kangkung yang menanam kangkung di Kecamatan Darussalam pada desa Tungkop, Lam reh, Lambiheu Sieum, Lambiheu Lambaro Angan, dan Lambada Peukan. Jumlah petani yang digunakan pada penelitian ini sebanyak 48 petani. Hasil penelitian menunjukkan bahwa faktor luas lahan dan faktor benih berpengaruh terhadap produksi kangkung sedangkan variabel pupuk dan tenaga kerja tidak berpengaruh terhadap produksi kangkung. Sedangkan faktor-faktor produksi belum berada pada kondisi yang efisien, dimana variabel luas lahan nilainya 1,66 yang artinya belum efisien sedangkan variabel benih dengan nilai 0,21 yang artinya tidak efisien. Pada elastisitas penggunaan faktor-faktor produksi kangkung bahwa semua variabel penggunaan faktor-faktor produksi kangkung berada pada kondisi inelastic karna E1. Factors that influence production Kale farming in Darussalam District Aceh Besar Regency This study aims to determine the factors that influence the production of kale farming in Darussalam sub-district, Aceh Besar district. This research was conducted in October and November 2021. The data used in this study were primary data and secondary data. Primary data were obtained from direct interview and distributing questionnaires to kale farmers in Darussalam District, Aceh Besar District. Secondary data is Collected and obtained from the central Statistics Agency and other agencies. The sampling method was carried out using the census method by taking the entire population of kale farmers who grow kale in Darussalam District in the villages of Tungkop, Lam Reh, Lambiheu Sieum, Lambiheu Lambaro Angan, and Lambada Peukan. The number of farmers used in this study were 48 farmers. The results showed that the land area and seed factors had an effect on the production of kale, while the fertilizer and labor variables had no effect on the production of kale. While the production factors are not yet in an efficient condition, where the land area variable is 1.66 which means it is not efficient while the seed variable has a value of 0.21 which means it is not efficient. In the elasticity of the use of kale production factors, all variables using the kale production factors are in inelastic conditions because E1.
This study aims to design a rain-shelter technology model in the red chili agribusiness cluster as an alternative policy to increase farmers’ income. This study uses the soft system dynamics methodology (SSDM), which is a systemic thinking modeling approach that can understand unstructured situations and contains the entire interaction between elements of an object through causal relationships as the basis for understanding the dynamic behavior of complex system of the object to assess the risks that occur in red chili agribusiness cluster. The research was conducted in the red chili production center in Aceh Tengah Regency. Identification of the need for cluster model done through literature and interviews with experts from stakeholders, namely practitioners and policy makers involved in the procedure of input supply, production, and marketing of red chili output. The primary data obtained through observation, in-depth interviews with respondents, as well as the activity of FGD (Focus Group Discussion), while secondary data obtained through the study of literature from various sources of literature, books, scientific journals, and a variety of publications related to this research. Formulation of model made by software Veneta Simulation (Vensim DSS), followed by simulation. The result of this research showed that the application of the rain-shelter technology model effectively had a positive impact on the quantity and quality of on-grade red chili production, so that it was able to meet industrial market demands and increase farmers’ income.
