Design of a Mobile Application for Providing Information to Advanced Level Students in Uganda

Education is the key to success in the existing world. Providing necessary information to students at the right stage of education that determines their future is useful to students, simplifies work, and reduces responsibilities for educators. Unfortunately, the existing ways of providing information to A'Level students in Uganda are unmodernized, and thus, important information is inadequately accessible to the students. Because of this, most students make uninformed decisions and study without focus. A prototype mobile application was designed to enable A'Level students to access necessary information about qualifications requirements, study materials, subjects, schools, etc. A rule-based method was also used to help students choose subjects that match their desired career options. The user interface design process followed a User-Centered Design approach to meet the students' requirements. SPSS software was used for analyzing the data, and results were obtained. The evaluation of the design showed that 95.76% of Advanced Level students who were participants agreed with the designed application prototype. This result indicated that A'Level students are interested in using mobile application technology to access information. This prototype design will ease students' getting information and ease educators' work, thereby saving the time wasted in attending to students physically to deliver all the necessary information.https://dorl.net/dor/20.1001.1.20088302.2022.20.2.2.7

Evaluation of Grafted Plants From Nine of Robusta Coffee Clones with Local Rootstock

Productivity of Robusta coffee in Indonesia were classified as low of about 685 kg/ha/year, due to did not use the superior clones and their propagation technique conducted by seeds. Efforts to address these issues are the using of high yielding superior seed (above 1,000 kg/ha) and then were propagated by grafting. The objective of this research was to evaluate the success rate and growth of grafted plants arised from nine clones of Robusta coffee with Sukabumi local rootstock. The study was conducted in a Greenhouse of Pakuwon Research Station, Indonesian Industrial and Beverage Crops Research Institute, Sukabumi. A randomized block design with 9 treatment of grafting combination and 3 replication were used in this study. The nine of treatment as follows: (1) BP 42 + local, (2) BP 969 + local, (3) BP 306 + local, (4) BP 436 + local, (5) BP 913 + local, (6) BP 534 + local, (7) BP 239 + local (8) BP 430 + local, and (G9) BP 358 + local. The results showed that the plant height, leaf number, leaf area, number of branches, and grafting success rate of BP 430 + local at 5 months after grafting (MAG) more higher than other grafting combination

The Compatibility of Five Superior Cacao Clones as Scions with Rootstock of Half-Sib Family of Sulawesi 01 Clone

Grafting is the most common cocoa propagation technique applied by farmers. One of the factors that determine the grafting success in cacao is the compatibility level between the scion and rootstock. The objectives of this research was to evaluate the grafting compatibility of half-sib family of Sulawesi 01 clone as rootstock with five superior cacao clones i.e. Sulawesi 01, Sulawesi 02, Sca 6, MCC 01, and MCC 02 as scions. The research was conducted at Pakuwon Experimental Station, West Java, at the altitude of 450 m above sea level with Latosol type of soil and B type of climate (Schmidt & Fergusson), from April to September 2015. This research used the randomized completely block design with five treatments of grafting combinations and five replications. Observation was taken at 14th, 21st, and 28th days after grafting on the total percentage of surviving graftings, percentage of sprouting grafting, percentage of grafting that have not sprouted, and bud sprouting rates. Data were analyzed by variance, correlation, and regression analysis. The results showed that the surviving grafting, the sprouting grafting and the rate of sprouting up to the 28th days after grafting varied among the scions. Based on the parameters observed, Sulawesi 01, Sulawesi 2, and Sca 6 demonstrated higher compatibility rate compared to MCC 01 and MCC 02. The results is applicable in seedling provision through grafting techniques in order to support cacao rejuvenation and or rehabilitation

Penentuan Karakter Pembeda Dua Populasi Kopi Arabika Di Kebun Percobaan Pakuwon Melalui Penggunaan Fungsi Diskriminan

Keragaman fenotipik dari beberapa genotipe tanaman karena pengaruh genetik dan lingkungan (GxE) dapat dianalisis melalui penggunaan fungsi diskriminan sehingga akan dapat diketahui informasi tentang karakter-karakter pembeda dari genotipe yang diuji. Penelitian dilakukan di Kebun Percobaan (KP) Pakuwon, Sukabumi, mulai bulan Desember 2010 sampai Mei 2012, dengan tujuan mengidentifikasi karakter-karakter yang dapat menjadi pembeda dua populasi kopi arabika (Kartika 1 dan 2) yang ditanam di KP. Pakuwon melalui pendekatan fungsi diskriminan. Contoh tanaman kopi varietas Kartika 1 dan 2 masing-masing sebanyak 20 tanaman dipilih secara sistematik, kemudian diamati pada umur 14-17 bulan setelah tanam terhadap 20 peubah morfologi tanaman. Data-data yang terkumpul dianalisis melalui penggunaan fungsi diskriminan. Hasil penelitian menunjukkan bahwa diperoleh 4 karakter pembeda dua varietas kopi arabika (Kartika 1 dan Kartika 2), yaitu jumlah cabang total/tanaman, jumlah ruas/cabang, jumlah tandan/cabang, dan bobot kering buah. Varietas Kartika 1 memiliki jumlah cabang total/tanaman, jumlah tandan/cabang, dan bobot kering buah lebih tinggi daripada Kartika 2, sedangkan jumlah ruas cabangnya lebih rendah. Keempat karakter tersebut secara nyata dapat membedakan kedua varietas kopi dengan tingkat validitasnya sebesar 82,5%. Hasil penelitian ini didasari oleh teori GxE dan dapat memberikan implikasi bagi kajian dan penelitian-penelitian berikutnya dalam upaya peningkatan produktivitas dan atau mutu hasil kopi, khususnya Kartika 1 dan 2 di KP. Pakuwon. .Determination of Characters to Distinguish Two Population of Coffea Arabica at Pakuwon Experimental Station by Discriminant Function Phenotypic variability of several plant genotypes is affected by genetic (G) and environment (E) factors, known as GxE. The GxE can be analyzed through discriminant functions being able to know information several characters as differentiator of genotypes. A study was conducted at Pakuwon Experimental Station (KP. Pakuwon), Sukabumi, from December 2010 to May 2012. To identify the characters being able to distinguish two populations of Coffea arabica (Kartika 1 and 2), the discriminant function was used. Sistematic sampling of 20 sample plants of Kartika 1 and 2 each was used in this study. As many as 20 variables of plant morphology were observed for 14-17 months after planting. Data collected were analyzed by discriminant function. Results showed that there are four characters being able to distinguish two varieties of Coffea arabica ( Kartika 1 and 2) namely: total number of branch/plant, number of internode/branches, number of bunch/ branch, and dry weight of fruit. The total number of branch/plant, number of bunch/branch, and dry weight of bean of Kartika 1 were higher than those of Kartika 2, while the number of internode/branches was lower. These fourth characters were significantly able to distinguish the two varieties of coffee with 82.5% validity rates. This result was based on GxE theory and may have implications for improvement of productivity and quality of coffee, for future study
