Phenology of Flowering Time and Flowering Duration of Cucumber Plants in Padang and Kamang Magek
Full text linkCucumber (Cucumis sativus L.) is a high-value horticultural crop widely used as fresh vegetables, processed food ingredients, and cosmetic products. In addition, cucumber contains important nutrients for health, such as vitamin C, vitamin K, and various essential minerals. As a plant with many benefits, cucumber is greatly influenced by climatic conditions, which can directly affect productivity and harvest quality. Based on this, a study on the phenology of cucumber plants under two different climatic conditions was conducted. This study used an experimental method involving 20 cucumber plants, with two location treatments and two replications. The observed parameters included the time of flower emergence and flowering duration. The study was conducted from September to December 2024 at two locations, Kamang Magek and Padang. The data were analyzed using a t-test with a significance level of 5%. The results of the study showed significant phenological differences between cucumber plants grown in Kamang Magek and Padang. Plants in Kamang Magek went through generative phases earlier, marked by earlier flower emergence, which occurred on day 25.4 after planting, compared to day 29.45 in Padang. The flowering duration in Kamang Magek was also shorter, lasting 7.9 days, compared to 10.55 days in Padang. These findings indicate that differences in climatic conditions between the two locations have a significant impact on the phenological development of cucumber plants
Exploration and Identification of Siamese Orange (Citrus nobilis Lour.) Plant diversity in Banyuwangi Regency
Full text linkSiamese orange (Citrus nobilis Lour.) is a horticultural product with significant economic importance in Indonesia. This study aims to identify the diversity of accessions of Siamese orange plants spread in Banyuwangi Regency, which is one of the main citruses producing areas in Indonesia. Exploration activities were carried out in several sub-districts with high potential for citrus cultivation. Data collection was carried out through direct field observations and interviews with local farmers, as well as morphological identification based on leaf, stem and fruit characteristics. The results showed that from five research locations, 2 clusters were obtained, which were concluded in 1 cluster as a group of Siamese orange accessions with phenotypic characters suitable for producing citrus fruits. There is significant morphological variation among Siamese citrus populations, especially in leaf and stem morphology. This variation reflects the genetic richness of local Siamese oranges that have the potential to be developed as superior varieties. This study provides important basic information for the preservation of genetic resources and the development of a breeding program for Siamese oranges in Banyuwangi
Potential of Bacteria Escherichia coli and Staphylococus aureus as Degradation Agent Waste Used Oil
Full text linkOil is one of the petroleum derivatives that cause environmental pollution. Oil used in the automotive industry such as workshops is often not managed properly, so that it becomes waste that can cause soil pollution and water pollution. One way that can be used to overcome this pollution is by bioremediation by utilizing Escherichia coli and Staphylococus aureus bacteria as bioremediation agents. The purpose of this study was to determine the ability of E.coli and S.aureus bacteria in degrading oil. The method used was experimental method. The results obtained show that E.coli bacteria have the ability to degrade waste oil by bioaccumulation which is characterized by the presence of oil clots in the center of the media. While S. aureus bacteria have the ability to degrade waste oil by biodegradation which is characterized by the decomposition and change in the shape of oil oil into white granules
Production Performance of Joper Chickens Fed with BSF (Black Soldier Fly) Maggots Cultivated in Different Media
Full text linkThe unstable price of animal feed is then carried out to find alternative feed. The purpose of this study was to evaluate the effect of giving maggots raised in different media on the production performance of Joper chickens. Maggots were raised with three different feed media. P1 25% blood, 50% bran, 25% market waste; P2 is the same as P1 24% market waste and 1% rice bran fried foods, and P3 is the same as P1 23% market waste and 2% fried food waste. Experiment Feeding 200 two week-old Joper chickens was done randomly in four treatments. P0 was given self-mixing feed, while P1, P2, and P3 were given additional feed 20% maggot flour in self-mixing feed maggot research results First. The results of the maggot research show that the best media for treatment P2 was BK 95.18%, ash 10.69%, KA 5.1%, LK 17.54%, SK 16.32% and PK 54.35%. The use of 20% maggots in Joper chicken feed has no significant effect on the production performance and percentage of Joper chicken carcasses, but there are tendency on the weight of P2 chicken carcass containing 1% fried waste. It is recommended to use 20% in the second research ration

Analisis Kesalahan Mahasiswa Pendidikan Matematika Dalam Menyelesaikan Soal Deret Tak Hingga Berdasarkan Teori Kastolan
Full text linkThis study analyzes errors made by mathematics education students in solving problems related to infinite series, focusing on a topic known for its conceptual and procedural complexity. Based on Kastolan's Theory, this research builds upon previous findings regarding students’ difficulties with infinite series material. A qualitative descriptive approach was employed to analyze the responses of 10 mathematics education students at Universitas Negeri Medan, who had taken or were currently taking the real analysis course, particularly the topic of infinite series. The participants were randomly selected. Data were collected through a structured Google Form questionnaire and two open-ended questions assessing convergence and the summation of geometric series. The errors were categorized into three types: conceptual errors, such as misinterpretation of convergence criteria (10%); procedural errors, including incorrect determination of the ratio (30%); and technical errors, such as calculation mistakes (40%), with percentages calculated using the formula . The findings indicate that while conceptual understanding was relatively sound, technical errors were most prevalent, especially in fraction operations and symbolic manipulation. The study recommends instructional approaches that integrate concept reinforcement, procedural scaffolding, and computational accuracy training. This research contributes to mathematics education by providing empirical evidence on common error patterns in advanced calculus and by encouraging instructors to strengthen teaching strategies that systematically combine conceptual understanding and procedural skills in solving infinite series problems.Penelitian ini menganalisis kesalahan dalam menyelesaikan soal deret tak hingga pada mahasiswa pendidikan matematika, dengan fokus pada topik yang dikenal memiliki kompleksitas konseptual dan prosedural.

Pengelompokan Stunting Di Provinsi Nusa Tenggara Timur Menggunakan Finite Mixture Partial Least Square (FIMIX-PLS)
Full text linkStunting is a chronic nutritional problem that affects the growth and development of children in developing countries, including Indonesia. The prevalence of stunting in Indonesia in 2023 reached 21.5%, with East Nusa Tenggara (NTT) Province recording a significantly high rate of 37.9%. This study aims to analyze the factors influencing stunting among children under five in NTT Province in 2023 using the Finite Mixture Partial Least Square (FIMIX-PLS) approach. The factors analyzed include healthcare services, socioeconomic conditions, environment, and immunization. The data analysis technique involved modeling using Partial Least Squares-based Structural Equation Modeling (PLS-SEM), beginning with construct validity and reliability testing, followed by data segmentation using FIMIX-PLS to identify heterogeneity and classify districts/cities based on the pattern of relationships among latent variables. The results of the analysis indicate the presence of data heterogeneity across regions, with several indicators showing significant variation between areas. These findings are expected to provide deeper insights into the contributing factors of stunting and assist in formulating more effective policies to reduce stunting rates in NTT.Stunting merupakan permasalahan gizi kronis yang berpengaruh pada pertumbuhan dan perkembangan anak di negara berkembang, termasuk Indonesia.
