Abstract

Indonesian government is trying to increase the production of agricultural commodities in order to support the food self-sufficiency program. To support this program, the availability of irrigation facilities is important in supporting the productivity of agricultural field. Climate change and changes in agricultural systems have an impact on changes in the need of irrigation water in crop cultivation. The decreasing availability of water for agriculture encourages us to be able to use water more efficiently, especially for irrigation water. The purpose of this research is to predict the ETp value as a basis for determining plant water requirements, to determine the most suitable ETp model, to validate the prediction results of ETp values ​​using direct measurements in the field, and to obtain information related to climate factors that have the most influence on the ETp rate. The measurement of the ETp value is based on the use of Merra-2 global climate data and climate data from field measurements. ETp models used are Blaney-Criddle, Hargraves, Remanenko, Penman and Penman-Monteith. Research results showed that the ETp rate in Wajo District tended to increase during the July-October period indicating an increase in water demand in crop cultivation. The most influential climate parameter in determining the Penman Monteith ETp rate is solar radiation. The results of the ETp analysis using global data show that the Penman model is the closest model to the Penman Monteith ETp model from field measurements.

Abstract

The drying method used can affect the drying characteristics and quality of the final product such as color parameters. The purpose of this research is to study the kinetics of Z. spina-christi leaves drying, find a mathematical model that best fits the drying characteristics, and analyze the color change of dried Z. spina-christi leaves and their brew. The drying process is carried out with 2 treatments, namely using a solar dryer and by drying in an open space using direct sunlight. There are 13 mathematical models of thin layer drying selected to simulate the drying characteristics of Z. spina-christi leaves. Identification of the Lab* value is used to calculate the browning index of the leaves due to the drying method used. The results stated that the solar power dryer could increase the drying rate of Z. spina-christi leaves, thus shortening the drying time. The Diffuision Approach model is the most accurate mathematical model in describing the drying characteristics of Z. spina-christi leaves for the two drying methods tested based on the resulting constant values. Each drying method affects the browning reaction of the dried Z. spina-christi leaves which also has an impact on the color of the brew, where drying in direct sunlight will produce a darker color of the dried leaves and brew.

Abstract

ABSTRAKPembibitan tanaman menggunakan polybag beresiko terhadap pertumbuhan akar yang cenderung melingkar, menyebabkan kerusakan akar tanaman saat proses pindah tanam, serta tidak ramah lingkungan. Oleh karena itu penelitian ini dilakukan untuk membuat biopot sebagai wadah pembibitan tanaman pengganti plastik polybag yang ramah lingkungan, serta mengkaji performanya. Penelitian ini menggunakan 2 faktor perlakuan, yaitu bahan dasar pembuatan biopot dan massa perekat. Pengujian yang dilakukan meliputi uji sifat fisik dan mekanik biopot, serta uji penanaman bibit cabai pada biopot. Hasil penelitian menunjukkan bahwa bahan organik ampas kelapa, cocopeat, dan arang sekam dapat digunakan sebagai bahan pembuatan biopot pengganti plastik polybag. Performa biopot tertinggi adalah pada kombinasi perlakuan bahan arang sekam dan perekat 175 g (AS-175), yang juga dipengaruhi oleh faktor kerapatannya. Perlakuan AS-175 juga merupakan perlakuan terbaik dari faktor kadar air dan daya serap air, sehingga biopot dengan perlakuan tersebut lebih awet digunakan untuk pembibitan dalam jangka waktu yang lebih panjang di lahan. Namun demikian perlakuan AS-175 tidak mampu menahan gaya luar sebaik biopot berbahan dasar cocopeat dan ampas kelapa karena sifat bahannya yang getas dan mudah patah, sehingga dalam penggunaannya sebaiknya menghindari benturan dan tekanan dari luar untuk mengurangi kerusakan. Kedua variabel penelitian maupun interaksinya tidak berpengaruh terhadap tinggi tanaman dan jumlah daun bibit cabai yang ditanam pada biopot. ABSTRACTPlant nurseries using polybags are at risk of root growth which tends to be circular, causing damage to plant roots during the transplanting process, and is not environmentally friendly. This research was conducted with the aim of making biopots as an environmentally friendly substitute for polybags, as well as assessing their performance. This study uses 2 variables, namely the basic material for making biopots and the mass of the adhesive applied. The tests carried out included testing the physical and mechanical properties of the biopot, as well as testing the planting of chili seeds in the biopot. The results showed that organic material from coconut pulp, cocopeat, and husk charcoal can be used as materials for making biopots for plant nurseries to replace polybags. The performance of the biopot produced for the highest biopot weight was in the combination treatment of husk charcoal and adhesive 175 g (AS-175), which was also influenced by the density factor. The AS-175 treatment is also the best treatment for the water content and water absorption factors, so that the biopot with this treatment is more durable for use in the field. However, the AS-175 treatment is not able to withstand external forces as well as biopot made from cocopeat and coconut pulps due to the characteristics of the material, so that in its use it is better to avoid impact and pressure from the outside to reduce damage. Both research variables and their interactions had no effect on plant height and leaf number of chili seedlings planted in biopots.
