Abstract

Fusarium wilt is an important disease of various types of bananas and one of the most common diseases that causes destruction of banana plants in tropical and subtropical regions. Fusarium wilt caused by the fungus Fusarium oxysporum f.sp. cubense (FOC). As an inhabitant, invader, soil-transmitted fungus and causes wilt that colonizes xylem vessels, FOC requires penetration through the roots of the host plant, so that in its control it is necessary to try to provide protection and induction of host resistance systems in the root system. in this research.The proposed banana plant disease detection system consists of two phases, in the first phase, namely in the learning process, the images of healthy banana leaves and those affected by fusarium disease are files each measuring 640x480 pixels obtained from the results of taking a digital microscope on the plantation. PT. GGP Lampung. Next is the classification process. The method used for pattern recognition in this study is a support vector machine (SVM). Basically SVM can only be used to classify data into two classes (binary classification). To be able to apply to the problem of classifying healthy banana leaves and those affected by mild, moderate and severe fusarium disease consisting of more than two classes, a multiclass SVM classification method is applied which is built by combining several binary classifications. In the training classification process, the hyperplane variables for each classifier obtained will be stored and will later be used as data for each classifier in the testing process, in other words the training classification process is a process to find support vectors, alpha and bias from the training input data obtained. in the form of a feature vector from the image of healthy banana leaves and those with mild, moderate and severe fusarium disease (four classes). From the results of the classification stage experiment using the support vector machine one against all method, the results obtained are Class I (Healthy Banana Leaf) 90.833%, Class II (Light Fusarium Banana Leaf) 76.688%, Class III (Medium Fusarium Banana Leaf) 77.50, Class III (Medium Fusarium Banana Leaf) IV(Fusarium banana leaf weight) 95%.

Abstract

Abstract Ujung Tebu is one of the villages located in the Ciomas sub-district, Serang Regency, Banten Province, which has a variety of uniqueness and characteristics of its people. The era of ever-increasing development will certainly push technology into every crevice of life. However, in this case, the backwardness of Ujung Cane Village in terms of infrastructure facilities, especially in RT 5 and RT 6, has encouraged the creation of an off-grid Solar Power Plant (PLTS) as a means of public street lighting (PJU). This effort is made to introduce and implement renewable energy as a means of supporting the green energy program. In addition, this off-grid Solar Power Plant (PLTS) is one of the environmentally friendly energy sources so that people do not have to worry about damage to the surrounding environment. Because the manufacture of this PJU still uses simple equipment, to optimize the resulting output power, it is necessary to analyze the efficiency of the output power based on the capacity of the solar cells used. Training activities for the installation and maintenance of Solar Cell Systems as PJUs have also been carried out well and as a result the community is able to independently carry out the installation and maintenance of PJUs integrated with solar cells. Abstrak Ujung tebu merupakan salah satu desa yang terletak di kecamatan Ciomas Kabupaten Serang, Provinsi Banten yang menyimpan berbagai keunikan dan ciri khas dari masyarakatnya. Era perkembangan zaman yang semakin meningkat tentu akan mendorong teknologi masuk ke setiap celah kehidupan. Namun dalam hal ini, ketertinggalan desa ujung tebu dalam pasilitas infra- struktur khususnya di RT 5 dan RT 6 mendorong timbulnya pembuatan Pembangkit Listrik Tenaga Surya (PLTS) off grid sebagai sarana penerangan jalan umum (PJU). Upaya ini dilakukan guna mengenalkan serta mengimplementasikan energi terbarukan sebagai sarana mendukung pro- gram green energy. Selain itu, Pembangkit Listrik Tenaga Surya (PLTS) off grid ini merupakan sa- lah satu energi yang ramah lingkungan sehingga masyarakat tidak perlu khawatir akan adanya kerusakan pada lingkungan sekitar. Oleh karena pembuatan PJU ini masih menggunakan peralatan yang sederhana, maka untuk mengoptimalkan daya keluaran yang dihasilkan perlu adanya analisis mengenai efisiensi daya keluaran berdasarkan kapasitas solar cell yang digunakan. Kegiatan pelatihan untuk pemasangan dan pemeliharaan Sistim Sel Surya sebagai PJU juga sudah dilakukan dengan baik dan hasilnya masyarakat mampu secara mandiri melakukan pemasangan dan pemeliharaan PJU terintegrasi dengan sel surya.

Abstract

Abstract Tunda Island is a small island located in the Java Sea, precisely to the north of Banten Bay. This area is included in the Tirtayasa District, Serang Regency. Tunda Island has an area of 289.79 hectares. The majority of Tunda Island residents work as fishermen/sailors. There are 300 heads of families (KK) living on Tunda Island. It is estimated that 300 heads of families can produce 2 liters of used cooking oil in one month per family, so the monthly estimate is around 600 liters per month. If used cooking oil is thrown away directly, it can pollute the environment. Therefore, it is necessary to process used cooking oil to convert it into something more valuable such as biodiesel. This is very relevant because the fuel requirements for fishing boats are quite high. The method used is community education with a training and counseling approach to increase the understanding of fishing communities regarding the use of used cooking oil waste into biodiesel. The activity will be carried out on September 11 2023 involving 10 fishermen. Based on the results of activities to obtain information data, training participants range in age from 28 years to 60 years. His daily work is as a fisherman. The results of the training showed an increase in knowledge about the use of used cooking oil, especially for conversion into biodiesel. Based on the results of activity evaluation through the distribution of questionnaires on the effectiveness of training activities, data was obtained, namely the effectiveness criteria received a score of 4.60 and entered the very effective criteria so that this activity had a positive impact on fishermen regarding the use of used cooking oil for biodiesel fuel Abstrak Pulau Tunda merupakan sebuah pulau kecil yang terletak di Laut Jawa, tepatnya di sebelah utara Teluk Banten. Kawasan ini termasuk dalam wilayah Kecamatan Tirtayasa, Kabupaten Serang. Pulau Tunda memiliki luas 289,79 hektare. Mayoritas penduduk pulau tunda berprofesi sebagai nelayan/pelaut. Terdapat 300 Kepala Keluarga (KK) yang tinggal di pulau tunda. Perkiraan dari 300 kepala keluarga tersebut dapat menghasilkan minyak jelantah 2 liter dalam satu bulan per KK sehingga estimasi perbulan sekitar 600 liter perbulan.

Abstract

Antibody production is becoming a trend, especially during a pandemic like now, although there have been many developments in antibody production in previous research. Antigen synthesis and characterization is one of the determining factors for the success of antibody production. This research developed a method of antigen characterization using the Nuclear Magnetic Resonance (NMR) method. The research conducted in these 4 stages begins with antigen synthesis, then continues with antigen characterization using NMR, then antibody production, and the last stage is antibody characterization using the Enzyme Linked ImmunoAssay (ELISA) method. The results of antigen characterization using NMR show that NAS has been perfectly conjugated with BSA and produces a NAS-BSA conjugate. This is shown by the presence of 1 methylene (CH2) olefinic at δH chemical shift of 6.27 ppm with an integral of 4 and having 1 piece of methine (CH) sp2 at δH chemical shift of 5.73 ppm with an integral of 2. NAS-BSA antigens have been shown to successfully produce antibodies. This is shown from the anti-NAS-BSA, NAS, and Acrylamide antibodies that begin to appear in the second, third and fourth boosting (respectively)

Abstract

The change from the 2013 curriculum to an Merdeka curriculum requires adjustments for teachers and students. The lack of availability of teaching tools that are in accordance with the Merdeka curriculum and a learning approach that is still teacher-centered makes students less motivated to participate in learning. The purpose of this study is to develop a PBL-based teaching module on green chemistry material by determining the validity, practicality, and effectiveness of student responses to the content measured in the teaching module. This research is R&D (Research and Development) research with the ADDIE (Analyze, Design, Develop, Implement, Evaluate) model. The data collection technique used a material and media validation questionnaire involving seven material and media expert validators and was analyzed using the Aiken's V test. Furthermore, the validated teaching module was tested limited to 26 class X phase E students. The development of this PBL-based teaching module obtained results in the validity of the material and media of 0.91 and 0.92 in the "Valid" category. Then it was implemented with students in class X-5 and received a response of 83.27% in the "Very Practical" category. Furthermore, the results of the LKPD assignment in the module obtained an average of 83.15% which indicates "Very Effective". Thus, this PBL-based teaching module is suitable for use as a learning tool.
