Most of the students stated that studying Physics using relatively thick textbooks tended to be boring. This has an impact on unsatisfactory learning outcomes. The purpose of this research is to develop a product in the form of a module that is compiled using the Predict-Observe-Explain (POE) learning model with a combination of learning videos from YouTube, and analyze the feasibility level. The research method used is by making a module on temperature and heat material, which includes learning videos in the form of a QR code that can be scanned via a smartphone. The parameters analyzed include the results of the validation of experts who include material experts, media experts, and linguists. Another parameter that was measured as the level of student interest in the module, with a sample of 10 students from SMAN 1 Dramaga, SMA Bumi Sejahtera, and SMA Hanura. The results showed that the assessments of material experts, media experts, and linguists respectively were 3.83, 3.32, and 3.47 with the criteria of "very decent". The attractiveness test results for SMAN 1 Dramaga, SMA Bumi Sejahtera, and SMA Hanura were 3.57, 3.36 with the criteria of "very interesting" and 3.03 with the criteria of "attractive". Thus, it is concluded that the POE-based physics module by utilizing the QR code and YouTube learning videos is very feasible to be used as a learning medium.

Queue often causes some problems, one of which is inefficiency in time and expense. PT Nirmala Agro Lestari is endeavoring to optimize the line of TBS truck transports on weight bridge. If the queue at weight bridge PT Nirmala Agro Lestari is going on constantly will result in its slow delivery of TBS to the production area and affect the quality of production. To avoid this, companies conduct queue simulations in order to determine whether the queue system is efficient or should be implemented as an adjustment. PT Nirmala Agro Lestari has always been trying to reach consumer demand targets, with production capacity of 60 tons/hour. The study used the method of queue theory by creating a model of queue simulations based on actual conditions using the promodel. The data on this study is from the TBS transport queue to the weight bridge of PT Nirmala Agro Lestari. The simulation steps on this research was to design an optimum model of line simulation with promodel and test the proposed model for a line model by calculating the workload of TBS trucks. Model modifications are needed because there is still a queue of buildup in the TBS weight bridge loading process. At weight bridge at 90,95%, there is high activity at weight bridge because of the time of service and the frequency of trucks over at the high harvest time that gives trucks a long line of time to enter the production process. The addition of weight bridge to two units shows a utilisation drop on the entry road to the weight bridge from 71.34% to 22.82%, and 90,95% to 62.30%.

In the last three years the climatic conditions in Jambi City have experienced erratic weather conditions. One way to predict rainfall is using the Kalman Filter approach. However, in this case, the Kalman Filter method is implemented on the forecasting results from ARIMA (Autoregressive Integrated Moving Average) because there has been rainfall measurement data from 2008 to 2017 at the BMKG Muaro Jambi Climatology Station which is also a function of time and the existing pattern will be described with using Time Series Analysis. Time series data is data that has a time series of more than one year on one object or data collected from time to time on one object. ARIMA model will be used to predict the next data. Kalman filter is a model part of state space that can be applied in forecasting models. The Kalman filter consists of a prediction stage and a correction stage. This method uses a recursive technique to integrate the latest observational data into the model to correct previous predictions and make further predictions. This study aims to determine the implementation of the kalman filter method in predicting rainfall obtained through the ARIMA model in Jambi City. The results of the 2018 Jambi City rainfall prediction research show that the best ARIMA model formed is the ARIMA model (1,0,1). In the Kalman Filter model, a MAPE value of 24.92% is obtained, which indicates that the Kalman Filter has a fairly good predictive ability.

The Brazilian trade balance shows positive surpluses every year, due to the strong performance of the Brazilian agribusiness, which has played a fundamental role in the country's economy. In view of the economic scenario the peppercorn culture has shown great importance in the Brazilian export market. Considered a commodity this has its transaction carried out through the stock exchange and oscillate through the world market. The present research aims to characterize the chain of black pepper production in the Brazilian scenario. The dynamics of pepper production chain in Brazil is established by its high added value in the product, basically its production is developed by family agriculture, where it shows its strong impact on the maintenance of labor in the field. The Brazilian productivity of black pepper is higher than the world average. However, the initial exploitation of black pepper requires high capital, besides presenting great variability in prices, even though it is a commodity. Being a demanding crop in nutrients and highly susceptible to fusariosis, it is essential to develop alternative exploitation, which can be consortium exploitation, in SAF, besides the technical assistance and organization of producers, to realize sales with volumes and quality in the processing (drying and cleaning) and production of differentiated products, such as white pepper, which has the highest final product value.

O tratamento de sementes (TS) e uma tecnica muito utilizada por produtores com o intuito de proporcionar condicoes favoraveis ao desenvolvimento inicial das plântulas. Nesse contexto, objetivou-se avaliar o efeito do uso de bioestimulante a base de hormonios vegetais sinteticos no tratamento de sementes de milho pipoca, e suas consequencias na produtividade e no atributo fisiologico das sementes resultantes da colheita. Para realizacao do experimento utilizou-se sementes de milho pipoca, as quais foram submetidas ao tratamento com o bioestimulante (Stimulate®) nas doses: 0; 6,25; 12,5; 18,75 e 25 mL de produto por quilograma de sementes, com quatro repeticoes. Para os componentes de producao avaliou-seo numero de sementes e de fileiras por espiga, massa de sementes por espiga e de mil sementes, numero de espigas por planta, comprimento e diâmetro de espigas, e produtividade. Em relacao aos atributos fisiologicos das sementes produzidas, avaliou-se a germinacao, massa fresca, comprimento da parte aerea, raiz e total de plântulas. Verificou-se que tanto a semente colhida como o desenvolvimento da planta foram influenciadas pelo TS combioestimulante. Dosagensde ate 25 mL kg-1, contribuiram na produtividade da cultura, sendo o ponto maximo de comprimento do sistema radicular de plântulas obtido com TS de 19,27 mL kg-1. Conclui-se que a utilizacao de bioestimulanteno TS nadosagem entre 19,27 a 25 mL kg-1 beneficia o atributo fisiologico de sementes e a produtividade da cultura do milho pipoca.
种子处理是生产者广泛使用的一种技术，目的是为幼苗的初始发育提供有利的条件。在此背景下，本研究旨在评价以合成植物激素为基础的生物刺激剂处理爆米花种子的效果，以及对收获种子产量和生理属性的影响。为了进行实验，我们使用了爆米花种子，用生物刺激素(Stimulate®)处理，剂量为:0;6, 25岁;12、5;每公斤种子18、75和25毫升产品，重复4次。对生产成分进行了评价:每穗种子数和行数、每穗种子质量和千粒种子、单株穗数、穗长、穗径和产量。根据种子的生理属性，对种子的萌发、鲜重、气长、根和幼苗总数进行了评价。结果表明，TS共生物刺激素对种子收获和植株发育均有影响。25 mL kg-1的剂量对作物产量有影响，TS为19.27 mL kg-1时幼苗根系长度的最大值。结果表明，在19.27 ~ 25 mL kg-1范围内施用生物刺激剂对爆米花种子的生理特性和产量均有好处。

Para realizacao do experimento utilizou-se sementes de milho pipoca, as quais foram submetidas ao tratamento com o bioestimulante (Stimulate®) nas doses: 0; 6,25; 12,5; 18,75 e 25 mL de produto por quilograma de sementes, com quatro repeticoes. Para os componentes de producao avaliou-seo numero de sementes e de fileiras por espiga, massa de sementes por espiga e de mil sementes, numero de espigas por planta, comprimento e diâmetro de espigas, e produtividade. Em relacao aos atributos fisiologicos das sementes produzidas, avaliou-se a germinacao, massa fresca, comprimento da parte aerea, raiz e total de plântulas.
