Abstract

The AquaCrop model is widely used under various agro-ecological conditions to reduce farm water consumption. The study aimed to simulate, validate, and measure the performance of AquaCrop models for canopy cover, biomass and soybean crop yields cultivated within a lysimeter. This research was conducted in the experimental field of the Faculty of Agriculture, the University of Jember, Indonesia (8°09'45.1" S, 113°42'58.2" E, 101 m a.s.l). There are four treatments in 4 lysimeters, namely P1 (irrigation based on recommendation), P2 (irrigation 95-105% FC), P3 (irrigation 75-85% FC) and P4 (irrigation 55-65% FC). The AquaCrop model is calibrated using canopy cover (CC) and then validated to predict the biomass and soybean yield. The experiment revealed that the model simulates better CC, biomass, and soybean yields with full irrigation than deficit irrigation. The performance of the AquaCrop model for soybeans of the Deja 2 variety in predicting CC, biomass, and soybean yield is impressive and reasonable. For the CC we found R2 ranges from 0.956 to 0.995, RMSE 10.389% to 3,293%, NRMSE 0.154% to 0.051%, NSE 0.918 to 0.992, and d 0.980 to 0.998. For biomass the R2 is 0.842, RMSE 0.111 t ha-1, NRMSE 0.017%, NSE 0.712, and d 0.937. For soybeans production the R2 is 0.999, RMSE 0.045  t.ha-1, NRMSE 0.018%,, NSE 0.908 and d 0.970. This study demonstrated that based on WUE, 55-65% FC irrigation is the most efficient application.

Abstract

 Jubung Village is the largest soybean producing area in Sukorambi District. The Farmer Group 'Tani Mulyo" experienced problems in soybean cultivation, namely soybean production which could not increase and the high price of fertilizer. The solution that can be given is the use of local microorganisms (MOL). MOL (Local Microorganisms) is a group of commonly cultivated microorganisms use in the "zero waste" concept is as a "starter" for organic composting. Materials and tools used were bamboo roots, granulated sugar, shrimp paste, rice bran, water, pan, stirrer, 20 L bucket, stove, cover and sprayer. The work program began with preparation of activities such as coordination with several stakeholders such as village officials, accompanying group lecturers, farmers and the Jubung village community. Next, socialization and practice of making local microorganisms (MOL) were carried out. This implementation is a practice of making local microorganisms (MOL) which is carried out at the home of one of the jubung farming communities. The production of local microorganisms (MOL) was accompanied by lecturers and carried out jointly with farmers. Indicators of the success of the work program which aims to develop the insight and skills of the community and farmers in improving the community economy with local microorganism entrepreneurship (MOL), and increasing the productivity of agricultural input products in Jubung village.

Abstract

Studies in transgenic sugarcane (Saccharum officinarum L.) demonstrated that sucrose transporter (SUT) genes were essential in sucrose translocations. Sucrose transporter gene isolated from sugarcane were designated as SoSUT1 and SoSOSUT2 respectively as encode protein of 518 and 747 amino acids. The genes were constructed into plasmid pYES2 for SoSUT1, and pYX112 for SoSOSUT2. cDNA SoSOSUT2 had also constructed into plasmid pBIN-At-GFP which was possible to trace the gene inserted. The constructed plasmid was transformed into yeast (Saccharomyces cerevisiae) and grown in minimal medium (SD–urasil) as selection medium. The transformed colony was confirmed using PCR. The functional expression was studied by growing yeast in YPD medium with 2% Sucrose, then the sucrose uptake was measured in number interval time using resorcinol method. The result showed that yeast INVSc1-pYES2-SoSUT1 and BF264- pYX112-SoSOSUT2 had higher ability in sucrose transport compared to the control-INVSc1 for SoSUT1 and control-BF264 for SoUT2. Moreover, the result showed that SoSUT1 had higher ability to transport sucrose than SoSOSUT2. Confocal microscope observation showed that transformation gene SoSOSUT2 was successful, which was indicated by green exposure of GFP protein.Keyword: sugarcane, sucrose transporter, yeast

Abstract

Kearifan lokal merupakan pandangan atau cara masyarakat dalam menghadapi berbagai permasalahan, termasuk budidaya kopi. Pemanfaatan teknologi berbasis kearifan lokal semakin ditinggalkan oleh masyarakat, dikarenakan msifnya teknologi modern yang ditransfer kepada masyarakat. Disisi lain penerapan teknologi berbasis kearifan lokal yang tepat cenderung masih memberikan dampak positif terhadap keberlanjutan usahatani kopi. Tujuan dari penelitian ini adalah untuk mengetahui persepsi petani dan faktor-faktor yang mempengaruhi keputusan mereka untuk menggunakan teknologi berbasis kearifan lokal dalam budidaya kopi. Manfaat penelitian ini adalah :  (1) memberikan kontribusi terhadap studi keilmuan yang berkaitan dengan persepsi  dan Keputusan adopsi inovasi teknologi berbasis kearifan lokal pada budidaya kopi yang berkelanjutan;  (2) secara praktis dapat diterapkan dan dikembangkan bentuk penyempurnaan bagi petani dalam proses adopsi inovasi teknologi budidaya kopi berbasis kearifan lokal; (3) secara implikasi sebagai bahan masukan dan pertimbangan bagi penentu kebijakan. Penelitian dilaksanakan pada bulan November 2022 di Tanggamus dan Lampung Barat Provinsi Lampung. Petani yang dijadikan sampel ada petani kopi rakyat sebanyak 140 petani. Data yang dikumpulkan adalah karakteristik sosial dan ekonomi petani responden, jenis teknologi berbasis kearifan lokal, persepsi dan adopsi teknologi kearifan lokal. Data dianalisis menggunakan regresi logistik untuk menentukan variabel yang mempengaruhi keputusan petani dalam mengadopsi teknologi berbasis kearifan lokal. Sementara itu, persepsi dianalisis menggunakan skala Likert. Hasil analisis menunjukkan keputusan adopsi inovasi teknologi berbasis kearifan lokal budidaya kopi secara simultan dipengaruhi oleh umur, pendidikan, pengalaman usahatani, luas lahan, produktivitas, keuntungan relatif, compatibility, complexity, trialability, observability. Namun secara parsial hanya 3 variabel yang mempengaruhi keputusan adopsi yaitu pendidikan, luas lahan dan kemudahan untuk dicoba (trialability). Persepsi petani terhadap budidaya kopi berbasis kearifan lokal dilihat dari karakteristik inovasi menunjukkan bahwa secara ekonomi cukup menguntungkan, sesuai dengan kebiasaan dan pengalaman petani, tidak rumit untuk dipraktikkan, mungkin untuk dicoba dan  mungkin untuk dilihat hasilnya.

Abstract

One of the commodities with the highest economic value in the plantation sector in Indonesia is coffee. In 2016 there was a significant difference between the area of robusta and arabica coffee, with the area of robusta coffee being superior. The wide difference between robusta and arabica coffee plantations is because robusta coffee is considered a potential opportunity in developing the community's economy compared to arabica coffee with a particular market. To improve the taste or quality of coffee production, one of the factors is the roasting process. Currently, the demand for coffee production is increasing with the need for maximum quality and taste of coffee beans, so the processing of coffee plants must be very concerned and improved. Therefore this study aims to determine the roasting technique with a roasting machine and its effect on improving the quality and taste of coffee beans that are popular with consumers. This study used a Split Plot Design (SPD) using the basic pattern of a completely Randomized Design consisting of 2 levels. The first factor is the roasting time as the main plot with four levels. Then the second factor is the roasting temperature with two levels. Each factor was repeated four times so there were 32 experimental units. The results of this study indicate that in the roasting process using slow roast and fast roast techniques, roasting time affects all observation parameters, namely moisture content, pH value, brix value, flavor, aroma, and caffeine. However, the roasting temperature only affects moisture content, brix value, and caffeine.

Abstract

Air preheater as a heat recovery technology is generally applied in the powerplant industry and used to heat combustion air, which increases the efficiency of the combustion chamber in the boiler. In this case, air preheater has tubular recuperative type typically located at the bottom of the circulating fluidized boiler for utilizing the lowest temperature exhaust gas. A significant presence of SO2 in the exhaust gas can lead to cold-end corrosion and cause leaks. The low tube thickness in the air preheater provides a good heat transfer performance unfortunately the corrosion issue has not been considered. By increasing the tube thickness, its aimed to extend the life time of the tubes with good corrosion resistance. This study is performed with calculations using empirical equations and validated results using Heat Transfer Research Inc (HTRI) software. Increasing the tube thickness impacts decreasing the heat transfer coefficient, increasing the flue gas (shell) pressure drop, and increasing the fouling factor. The tube thickness which determined for the corrosion prevention design of the air preheater give an overdesign of 18.14%, a heat transfer rate coefficient of 1.726 Btu/hr. ft2. °F, a shell pressure drop of 0.000541 psi, and a fouling factor of 0.114 hr. ft2. °F/Btu.
