Abstract

This study compares the degree of adaptation of four shallot varieties introduced to the sub-optimal land of Wamena with one local variety. The study determined the physiological processes of plants observed 5 and 11 weeks after planting. The results show that the best-adapted shallot is the local variety which is indicated by the parameter of harvest index (0.820). In addition, the results showed that the local Wamena variety produced high production with a high assimilation rate (0.072 g/dm2week-1), had a leaf area (41,750 cm) and a high leaf area value (0.465 cm) even though it was indicated by treatment without fertilizer application. Liquid organic (control treatment). Compared with the introduced varieties, which showed no significant effect on each liquid organic fertilizer treatment level. The difference in responses shown by each variety is influenced by the genetic ability of each variety which is supported by environmental conditions.

Abstract

Payment systems continue to evolve alongside advancements in information technology, driving the digitization of financial services and payment instruments. This study examines the influence of Psychological, Socio-Cultural, and Personal Factors on adopting electronic money and the growth of a cashless society, with Financial Technology as a moderating variable. The research involved 1,000 Bank BNI customers in the Jabodetabek area (Jakarta, Bogor, Depok, Tangerang, and Bekasi) actively using BNI Mobile Banking services. The analytical methods employed include Discourse Network Analysis and Structural Equation Modeling to develop a comprehensive analysis model. The results indicate that psychological and personal factors—such as motivation, perception, learning, positive attitude, modern lifestyle, and openness to change—significantly influence electronic money usage. However, socio-cultural factors do not exhibit a significant impact, primarily due to persistent cash usage habits and a lack of trust in technology. This study highlights the need for financial education to promote awareness of electronic money benefits and security, develop tailored financial products, and enhance regulatory collaboration between the government and relevant institutions.

Abstract

This study aims to analyze the usability level of the learning tool monitoring system developed to support the digitalization of learning administration management in the educational environment. Usability is a crucial aspect in the successful implementation of the system, because it is directly related to the convenience, comfort, and effectiveness of use by teachers, supervisors, and education staff. This study uses a descriptive quantitative approach with evaluation instruments that refer to six usability characteristics, namely appropriateness recognizability, learnability, operability, user error protection, user interface aesthetics, and accessibility. Data was collected through the distribution of questionnaires to the respondents of the users of the system, and analyzed using descriptive statistics. The results of the analysis show that the system has an average usability value of 4.50 or 90.04%, which is classified as very good. The characteristics with the highest scores were accessibility (90.64%) and user interface aesthetics (90.42%), while the lowest scores were appropriateness recognizability (89.57%). These findings indicate that the system has met most of the users' expectations, especially in terms of the interface appearance, ease of access, and learning process of using the system. However, the aspects of function recognition and navigation still need to be slightly improved to be more optimal.

Abstract

Bejana bertekanan dalam hal ini adalah tangki MFO, didesain untuk menahan gas atau liquid pada tekanan yang jauh berbeda dengan tekanan normal. Berbagai bentuk tangki yang selama ini digunakan sebagai bejana bertekanan antara lain spheres, cylinders dan cones. Namun, karena sulitnya manufaktur membentuk lingkaran atau sphere, maka desain dengan bentuk silinder lebih banyak digunakan. Metode yang digunakan dalam penelitian ini menggunakan studi lapangan dan software untuk mengetahui kekuatan material bahan tangki MFO yang aman, Dari hasil perhitungan bahwa tegangan-tegangan yang terjadi yaitu tegangan longitudinal dan tegangan keliling, yang terbesar terjadi pada tegangan keliling dengan menggunakan las tumpang yaitu sebesar 4,832 MPa untuk material AISI 304 L, dan tegangan termal akibat beda suhu besarnya adalah 4,486 MPa pada suhu 100oC, tetapi masih lebih kecil dari tegangan yang izin bahan. Semakin besar suhu yang terjadi semakin besar tegangan termal yang terjadi tetapi masih lebih kecil dari tegangan izin bahan. Dan semakin tebal dinding tangki (5 mm menjadi 6 mm), maka semakin kecil tegangan yang terjadi (8,528 MPa menjadi 7,106 MPa, tetapi masih kecil dari tegangan izin bahan (56,819 MPa).

Abstract

Ramalina sp. (Ramalinaceae) is a type of lichen known to contain many active secondary metabolite compounds that have the potential to be used as medicine or medicinal raw materials. One of the biological activities possessed by Ramalina sp. lichen is its anticancer activity. This research aims to isolate and identify active secondary metabolite compounds from the methanol extract of the Ramalina sp. lichen and to find out the cytotoxic activity of the isolated compound against MCF7 breast cancer cells. Compound 1 (usnic acid) was successfully isolated from fraction A. The isolation and purification process was carried out starting with a maceration process using acetone solvent, followed by silica gel column chromatography using a gradient solvent system consisting of n-hexane, n-hexane:EtOAc, EtOAc, EtOAc:MeOH, and MeOH with 5% increment of polarity to obtain 17 fractions (F-1 to F-17). From the 17 fractions obtained, fraction 3 (F-3) and fraction 4 (F-4) (eluted with n-hexane:EtOAc 30%), which had the same TLC profile, were combined and named as fraction A. Compound 1 (50 mg) is a yellow needle crystal that was formed in a bottle of fraction A, which was obtained after the process of combining fractions F-3 and F-4 and solvent evaporation process. The crystals were then separated and purified with CHCl3 and MeOH. Compound 1 was then characterized based on spectroscopic data. Various spectroscopic analysis data, including FTIR, 1D- and 2D-NMR, and LC-ESI-MS, show that Compound 1 is a dibenzofuran derivative compound with 18 carbons (3 from carbonyl groups (C=O) and 3 from methyl groups) and 2 hydroxyl (-OH). Cytotoxicity assay showed that at a low concentration of 18.75 ug/mL, Compound 1 caused a 67.06% decrease in MCF7 viability

Abstract

This study aims to determine the percentage of the presence of fungi associated with processed coffee beans that freshly harvested and those that have been stored for 6 months and identify the fungi found at least to the genus level. This research was conducted from July to September 2021 at the Agricultural Biotechnology Laboratory, Faculty of Agriculture, University of Lampung. The method used was a survey method. Coffee beans samples were taken in Sedayu Village, Semaka District, Tanggamus Regency. Samples of coffee beans were taken at different season, namely in October 2020 and April 2021. The types of processed coffee that would be identified were natural, honey and lowgrade. The method used in this study was the direct plating method using PSA (Potato Sucrose Agar) media and repeated 5 times by putting 5 coffee beans in each petri dish. The variables in this study were identification of fungi based on their macroscopic and microscopic properties and analysis of  index diversity. The results showed that as many as six fungi were found to be associated with coffee beans, namely, Aspergillus niger, Aspergillus fumigatus, Aspergillus flavus, Aspergillus parasiticus, Phytophthora sp. and Penicillium sp. The most commonly species was found, Aspergillus niger, which was 64% found in processed coffee from the 2021 harvest year. The result of the analysis show that the fungi diversity index (H’) of low grade coffee beans in the 2020 harvest season and natural processed 2021 classified as moderate diversity (1 ≤ H’ ≤ 3). While, other processed products are classified as low diversity (H < 1).

Abstract

Identification is an important activity in the management of plant diseases because by knowing the identity of the fungus found in cocoa beans, a strategy can be determined as a first step before controlling the fungus to prevent the spread of the fungus. This research aims to determine the fungi associated with the MCC 01, MCC 02, Sulawesi 1, and THR clones on uncontrol handling and controlled handling cocoa beans and to determine whether uncontrol handling and controlled handling reduce inoculum sources to suppress fungi growth and development. This research was conducted at the Laboratory of Plant Diseases, Faculty of Agriculture, University of Lampung from January 2023 to March 2023. This research was carried out by testing the agar method (agar plate), the media used was potato sucrose agar (PSA). There were four samples of cocoa bean clones, namely MCC 01, MCC 02, Sulawesi 1, and THR from Kuta Dalom Village, Pesawaran Regency, which were grown on 128 plates of PSA media (64 plates using 2% NaOCl and 64 plates without NaOCl) for each clone. Cocoa beans contained 32 cups each uncontrol handling and controlled handling. So there are 128 cups of PSA media. Isolates that have been obtained are then identified 7 days after isolation. Observations in this study were carried out macroscopically and microscopically. Macroscopic observations were carried out to differentiate growing fungi based on the color, shape and size of the colonies. Meanwhile, microscopic observations were made to differentiate growing fungus based on the structure of the fungi body. The results showed that from the uncontrol handling and the controlled handling, three fungi were found, namely Aspergillus flavus, Aspergillus niger, and Rhizoctonia sp. The fungi Aspergillus flavus and Aspergillus niger show that controlled handling can reduce the source of inoculum compared to uncontrol handling. In contrast to the fungi Aspergillus flavus and Aspergillus niger, the fungi Rhizoctonia sp. shows that controlled handling cannot reduce the source of inoculum. Key words:  Aspergillus, bean, cocoa, Rhizoctonia, handling

Abstract

Mesin diesel merupakan sebuah mesin konversi energi yang mengubah energi thermal hasil reaksi kimia antara bahan bakar dan udara menjadi energi mekanik, berupa Torsi pada poros engkol (crankshaft), kemudian daya yang dihasilkan oleh mesin diesel ditentukan oleh jumlah bahan bakar yang dapat terbakar dengan sempurna di dalam ruang bakar, tujuan dalam penelitian ini adalah untuk mengetahui pengaruh suhu pendingin terhadap daya serap kalor mesin pendingin dan kinerja yang dihasilkan oleh mesin diesel.dan dari hasil penelitian ini ada beberapa hal yang penting diantaranya adalah dengan peningkatan putaran mesin umumnya dapat meningkatkan daya mesin, selama tekanan efektif tetap stabil. Namun, jika kecepatan terlalu tinggi tanpa pembakaran yang sempurna, tekanan efektif bisa turun dan efisiensi berkurang, semakin tinggi putaran mesin, semakin banyak panas yang harus diserap oleh sistem pendingin air tawar. Sehingga sistem harus dirancang untuk menjaga suhu tetap stabil meskipun pada beban dan putaran tinggi, dan semakin tinggi putaran mesin, semakin besar panas yang dialirkan ke sistem pendingin, sehingga sistem pendingin air laut harus mampu mengimbangi panas tersebut agar suhu air tawar tetap terjaga dan mesin tidak mengalami overheating
