Chrysanthemum is an ornamental plant widely cultivated in Indonesia, with various varieties that have unique and attractive characteristics. Each variety responds differently to changes in light intensity. Providing shade can help regulate the light intensity received by chrysanthemum seedlings during the acclimatization stage. This study aimed to determine the best shade percentage for the acclimatization growth of three chrysanthemum varieties. The research was conducted in the screenhouse of the Faculty of Agriculture, Tanjungpura University, for three months, from October to December 2024. The experiment used a Split Plot Design (Split Plot) with a Randomized Block Design (RBD), consisting of two factors: shade percentage and variety. There were three levels of shade and three chrysanthemum varieties, resulting in nine treatment combinations. Each treatment was repeated three times, with each replication consisting of three sample plants, resulting in 81 experimental units. The shade percentages used were 25% (n1), 50% (n2), and 75% (n3), and the varieties tested were Xanne (v1), Suciyono (v2), and Pinka Pinky (v3). Observed variables included plant survival rate, plant height, stem diameter, internode length, number of internodes, number of flower primordia, leaf color changes, along with supporting data such as temperature, humidity, and light intensity. The results showed that 50% shade was effective in promoting plant height and the number of flower primordia in the three varieties: Xanne, Suciyono, and Pinka Pinky. The Suciyono variety exhibited good vegetative and generative growth under all shade percentages.

This study analyzes the forms of risk and risk management strategies in melon farming in Brebes as an impact of climate change. A descriptive qualitative approach was applied using a case study through in-depth interviews with a farmer who has more than ten years of experience, supported by secondary data from BPS, BAPPENAS, and related literature. The findings reveal four categories of major risks: market, financial, operational, and socio-environmental. High-level risks include climate variability, yield decline, and pest attacks. Medium-level risks involve production costs, water management, and price fluctuations, while low-level risks consist of limited weather information and agricultural extension services. Current strategies are still basic, including fertilization, pesticide application, and water channel arrangement. Strengthening adaptation is needed through irrigation technology, climate-resilient varieties, marketing diversification, and improved access to information and institutional support.

Coffe is one of Indonesia’s leading commodities, known for its diverse flavors and aromas. Traditionally, coffee quality assessment is conducted manually through cupping tests performed by expert panelists. However, this method is subjective and requires considerable time and cost. This study aims to implement an Artificial Neural Network (ANN) using the backpropagation algorithm to classify coffee types based on sensory parameters such as flavor, aroma, acidity level, and body. Simulated data were generated from five common Indonesian coffee varieties: Arabica Gayo, Robusta Lampung, Arabica Toraja, Liberica Jambi, and Excelsa. The results show that the ANN-based classification system with a 4-8-1 architecture achieved an accuracy rate of 93% after 500 training epochs, with a final error value of 0.07. The implementation of this method provides an efficient and objective technological alternative to assist the coffee industry in maintaining product quality and automatically identifying coffee types.    

The Damahu waxy corn (Zea mays L. var. Damahu) is a local variety traditionally cultivated by the Gorontalo community and possesses significant potential for the development of functional food products. This study aimed to determine the nutritional composition of the Damahu waxy corn variety originating from Bontula Village, Asparaga District, Gorontalo Regency, through proximate analysis. The corn samples were dried, milled, and analyzed using standard analytical procedures to quantify moisture, ash, fat, protein, and carbohydrate contents. The results indicated that Damahu waxy corn flour contained 83.32% carbohydrates, 5.93% protein, 1.67% fat, 8.84% moisture, and 0.24% ash. This composition characterizes the Damahu variety as a good energy source. However, its protein content does not yet meet the minimum requirement set by the Indonesian National Standard (SNI) for corn-based processed products. The nutritional profile highlights the potential of Damahu waxy corn for the development of nutritious and competitive local food products. This study provides an initial contribution to the documentation of Gorontalo’s indigenous corn varieties and offers a scientific foundation for the utilization of local germplasm to strengthen regional food security.

In line with this national rice productivity improvement strategy, the Situbondo Regency Government in East Java Province is actively participating in initiating the development of new superior rice varieties. In early 2023, Situbondo Regency released a new superior rice variety, the Bk Situbondo 01 Agritan Variety. This new rice variety was developed for the IP 400 program. In 2024, the cultivation of this superior rice variety, Bk Situbondo 01 Agritan, began in several villages, one of which was in Battal Village, Panji District, primarily by the Joyo Mulyo 3 Farmers Group. In this regard, it is deemed necessary to conduct research to determine the income and financial efficiency of the superior rice variety Bk Situbondo 01 Agritan. The results of the study indicate that financially the income is recorded as profitable and the farming is efficient. Financially, if it is calculated that there is a decrease in the amount of production and a decrease in production prices of up to 15%, as well as an increase in variable costs of up to 15%, assuming that other factors are considered constant, the new superior rice variety farming business Bk Situbondo 01 Agritan, recorded that the income is still profitable and the farming business is still efficient. It can also be seen that the factors: (a) decrease in the amount (quantity) of production, and (b) decrease in production prices, are relatively more sensitive in responding to the decrease in the level of income and efficiency of the farming business, when compared to the factor: (c) increase in variable costs of the farming business.

Seeds that have exceeded their shelf life generally experience a decline in physiological quality, particularly in terms of viability and vigor. This study aims to determine the viability and vigor levels of several rice (Oryza sativa L.) varieties of Foundation Seeds (Benih Pokok/BP) after surpassing their shelf life. The tested varieties included Inpari 16, Inpari 42, Inpari 45, Sunggal, Memberamo, and Ciherang, obtained from Wonoketro Village, Jetis Subdistrict, Ponorogo Regency.

Successful pollination in oil palm depends heavily on the availability of Elaeidobius kamerunicus pollinator insects that require anthesis male flowers as habitat and food sources. This study aimed to analyze the relationship between anthesis male flower availability on E. kamerunicus beetle population and its impact on parthenocarpy bunch formation at PT. Graha Inti Jaya, Central Kalimantan. Observational method with descriptive and correlational approaches was conducted on 484.57 hectares of oil palm plants varieties Socfindo and Lonsum planted in 2007-2008 during February-July 2025 period. Data collection included anthesis male flower census, beetle population monitoring using yellow traps, and parthenocarpy bunch analysis from mill sorting. Data analysis used linear regression, Pearson correlation, and two-way ANOVA with 95% confidence level. Results showed significant relationship between anthesis male flower availability and E. kamerunicus beetle population (R² = 0.728, p < 0.05), where each unit increase of anthesis male flower increased beetle population by 2,667 individuals per hectare. However, relationship between beetle population and parthenocarpy bunches was not significant (R² = 0.114, p > 0.05), indicating complexity of pollination factors. Variety and planting year differences showed no significant effect. This study recommends maintaining anthesis male flower availability >5% per hectare for optimal natural pollinator beetle population.

This study aims to utilize data mining techniques, specifically the K-Nearest Neighbors (KNN) algorithm, to classify leaf diseases in sugarcane (Saccharum officinarum). Early and accurate detection of leaf disease types is a crucial step in prevention and control strategies, thereby reducing potential crop losses caused by pathogen attacks. Leaf diseases in sugarcane, such as leaf scald, rust, and mosaic virus, are known to affect photosynthesis, inhibit growth, and reduce the quality and quantity of sugarcane produced. The classification process in this study was carried out through image analysis of infected sugarcane leaves, where features such as color, texture, and shape were extracted using digital image processing techniques. The KNN algorithm was chosen because of its non-parametric nature, ease of implementation, and its ability to provide accurate classification results even with limited data size. The working principle of KNN is to determine the class of a new sample based on the majority class of its k nearest neighbors in the feature space, making it very suitable for the case of leaf disease image classification. In addition to building a classification model, this study also examines disease prevention strategies based on the identification results. These strategies include the use of disease-resistant sugarcane varieties, the implementation of appropriate planting patterns, land moisture management, regular plantation sanitation, and the measured and environmentally friendly use of pesticides or fungicides. Model performance evaluation was conducted using accuracy, precision, recall, and F1-score metrics to assess model effectiveness across various data scenarios. The results of this study are expected to not only contribute to the development of decision support systems for farmers and related parties but also support the application of artificial intelligence-based technology in the agricultural sector.

This study aims to analyze strategies that can be applied to expand production and increase the productivity of cayenne pepper plants. The method used in this study is a qualitative descriptive method with a field study approach in several cayenne pepper production centers. Data collection techniques were carried out through observation, interviews with farmers, and literature studies. The results of the study showed that land expansion strategies through the utilization of idle land and intercropping systems, as well as the application of technologies such as the use of superior varieties, drip irrigation, and balanced fertilization can significantly increase crop yields.  

Indonesia's democracy, despite over two decades of progress since the fall of the New Order regime, has faced stagnation and democratic backsliding in recent years. Indicators from institutions such as the Economist Intelligence Unit (EIU), Freedom House, and Varieties of Democracy (V-Dem) consistently highlight a decline in democratic quality. Contributing factors include identity politics, declining electoral integrity, political dynasties, and weak institutional capacities, described as "Low-Capacity Democracy." This study employs a qualitative approach to explore these challenges, including literature reviews, document analysis, and interviews. The findings reveal systemic issues at both institutional and societal levels, including weakened oversight bodies like the Corruption Eradication Commission (KPK), the dominance of executive power, and the rise of transactional politics and political dynasties. Digital challenges, such as disinformation and low digital literacy, also exacerbate these issues. This study recommends comprehensive reforms, such as strengthening independent institutions, enhancing transparency in public fund management, and improving political education to reduce transactional practices. Digital media regulations and technology-based electoral monitoring are also proposed to increase transparency. By addressing these issues, Indonesia can reinforce democratic resilience and foster an inclusive, accountable political system.

Agrotechnology plays a crucial role in increasing agricultural productivity through the implementation of modern innovations and technologies. Challenges such as land degradation, climate change, and limited natural resources can be addressed through precision technology, smart irrigation, biotechnology, and agricultural mechanization. This study employs a literature review method by analyzing various studies from 2019 to 2024 that discuss the impact of agrotechnology on agricultural yields. The findings indicate that the application of precision irrigation systems can enhance water use efficiency by up to 40%, while the use of genetically engineered superior crop varieties can increase yields and improve plant resistance to pests and diseases. Additionally, the utilization of digital technology, such as the Internet of Things (IoT), enables more efficient and data-driven land management. However, major challenges in implementing these technologies include limited farmer access, high investment costs, and low digital literacy among farmers. Therefore, policy support, financial incentives, and farmer training are necessary to ensure the widespread and sustainable adoption of technology. Thus, agrotechnology can serve as a primary solution for increasing agricultural productivity while maintaining environmental sustainability.

This study aims to evaluate the effect of grafting and budding techniques on the growth and success of avocado (Persea americana) plant propagation. Grafting and budding techniques are vegetative methods commonly used in horticultural plant propagation to maintain the genetic quality of the parent plant. The study was conducted using avocado plants with grafting and budding techniques on the rootstock. The parameters observed included the level of success of unification (compatibility rate), shoot growth rate, survival percentage, and growth in stem diameter and plant height during a certain period. The results showed that the grafting technique provided a higher success rate than the budding technique on certain varieties, with a survival percentage reaching 85%. However, the budding technique showed advantages in the parameter of shoot growth rate, especially on varieties with specific or better environmental adaptation. This study shows that choosing the right propagation technique, depending on the characteristics of the variety and environmental conditions, is a key factor in supporting the success of avocado plant propagation. These findings are expected to be a reference for farmers and researchers in optimizing the production of high-quality avocado seedlings.

The research was conducted at the Horticulture Seed Center, observing the growth and success of plant unions. The results demonstrate that both techniques effectively enhance plant quality, with budding showing faster results in citrus and grafting improving avocado resilience to environmental conditions. This study provides guidance for farmers to select optimal propagation methods tailored to their plants' specific needs.

Purple corn is one of the corn varieties that is being developed by Indonesia as a form of food diversification. The purple color of corn is produced by the high presence of anthocyanins so it can provide health benefits such as antioxidant, anti-inflammatory, mutagenic, anti-cancer and anti-angiogenesis. To ensure that the bioactive components are not damaged, extraction is carried out in stages by applying the maceration method using a polar solvent with the correct ethanol content of 96%. Apart from using the appropriate solvent, the length of maceration time will determine the results of the extract obtained. This research aims to find out how long maceration affects the content of bioactive compounds found in purple corn. The research used a completely randomized design with one treatment, namely maceration times of 12, 24 and 48 hours. The tests carried out included color intensity, total phenol and anthocyanin content and antioxidant activity. The research findings explain that the length of maceration has a significant effect on color intensity, total phenols and antioxidant activity of purple corn extract. 2 hour maceration was the best treatment in extracting bioactive compounds, namely total phenols of 206.29 g/100 g, total anthocyanins of 0.19 g/100 g and antioxidant activity of 58.80%.

Previously, germination was reported in many studies that could improve the nutritional status and bioactive compounds in brown rice. However, the change of those functional properties was randomly different in diverse varieties. This study aimed to evaluate the change in chemical composition and functional properties of germinated brown rice from the Mentikwangi variety, one of the local paddy rice in Indonesia. Brown rice was germinated using the soaked and aeration method for 48 h. After that, the proximate compositions were analyzed including the change of total phenolic compounds and radical scavenging activity. We observed that germination in Mentikwangi brown rice significantly increased the crude protein content, but reduced the lipid and total carbohydrate contents. Moreover, the antioxidant activity was improved in germinated Mentikwangi brown rice sample due to the improvement of total phenolic compounds. These results affirm the previous studies which concluded that germination attenuated the functional properties of brown rice, so that has the potential to be developed as a future functional food.
