The cross-elasticity value of 1.64 confirms the elastic substitution relationship between corn and rice. These findings highlight the potential of corn as a substitute for rice in maintaining stable food consumption despite fluctuations in staple commodity prices.       

Sweet corn is a horticultural commodity that is widely consumed in Indonesia. This study evaluated the effectiveness of NPK 18-18-18 fertilizer on the vegetative growth, yield components, and relative agronomic effectiveness (RAE) of sweet corn (Zea mays saccharata). Field experiments were conducted using fertilizer dosages of 0,50, 0,75, 1,00, and 1,50 NPK, with a control treatment for comparison. The application of NPK 18-18-18 significantly increased plant height, stem diameter, leaf number, ear length, ear diameter, biomass weight, ear weight with husk, ear weight without husk, plot yield, and overall productivity compared with the control. Mean values across treatments ranged from 68,94–205,72 cm for plant height, 7,41–20,47 mm for stem diameter, 6,01–13,00 leaves per plant, 15,41–20,89 cm for ear length, and 36,05–49,65 mm for ear diameter. Biomass weight ranged from 0,12–0,34 kg, ear weight with husk from 0,13–0,34 kg, and ear weight without husk from 0,12–0,28 kg. Plot yield varied between 7,91–25,46 kg, corresponding to productivity levels of 5,02–16,16 t/ha. RAE analysis indicated that fertilizer application was effective at dosages of 0,75, 1,00, and 1,50 NPK, with the highest effectiveness observed at 1,50 NPK (118%). Notably, the 0,75 NPK dosage achieved an RAE value of 101%, demonstrating that lower fertilizer input can enhance yield while reducing production costs and mitigating fertilizer scarcity. These findings suggest that NPK 18-18-18 fertilizer, when applied at an optimal dosage, can be effectively utilized in sweet corn cultivation to improve growth and productivity while ensuring efficient nutrient management.

Corn production in the provinces of East Nusa Tenggara (NTT) and West Nusa Tenggara (NTB) exhibits dynamics influenced by agro-climatic factors, the utilization of production facilities, and the welfare condition of the farmers. This study aims to analyze the impact of rainfall, solar radiation, and production inputs on corn productivity; to explain the relationship between production changes and the Farmer’s Exchange Rate (NTP) as a welfare indicator; and to evaluate the contribution of the corn subsector to the agricultural Gross Regional Domestic Product (GRDP). The research method uses a descriptive-quantitative approach based on BPS data and official local government documents. The results indicate that NTB has more stable productivity due to relatively even rainfall and better support for production facilities, whereas NTT faces higher production fluctuations due to greater climate variability. Furthermore, the NTP in NTB tends to be better than in NTT, aligning with the stability of its productivity. Corn contributes significantly to the agricultural GRDP in both provinces, particularly in central production areas such as Dompu and Bima. Policy implications include the necessity for strengthening post-harvest infrastructure, more equitable input distribution, and climate adaptation strategies in drought-prone areas. The findings provide an empirical basis for sustainable productivity improvement and farmer welfare policies.

Background: Patient safety culture forms the cornerstone of safe and high-quality healthcare delivery. However, its implementation often encounters barriers, particularly the persistence of a blaming culture that discourages staff from reporting patient safety incidents. Clinical leadership and the intensity of incident reporting are believed to play a pivotal role in shaping and sustaining a positive patient safety culture.Objective: This study aims to examine the influence of clinical leadership and patient safety incident reporting intensity on patient safety culture, with blaming culture serving as an intervening variable at Sentra Medika Cikarang Hospital.Methods: A quantitative research approach with an explanatory design was applied. The study involved 147 nurses selected through stratified random sampling. Data were collected using structured questionnaires and analyzed using Structural Equation Modeling (SEM) with the Partial Least Squares (PLS) method to test the direct and indirect relationships among variables. Results: The findings revealed that both clinical leadership and incident reporting intensity significantly influence patient safety culture, both directly and indirectly, through the mediation of blaming culture. Strong clinical leadership and a high level of incident reporting were associated with a more positive patient safety culture, while a high blaming culture weakened this relationship. Conclusion: The study underscores the importance of fostering supportive clinical leadership and cultivating a non-punitive reporting environment to strengthen patient safety culture. Hospital management should focus on leadership development and the creation of open, blame-free communication systems to enhance safety outcomes.

Left ventricular hypertrophy (LVH) can be identified through both electrocardiography (ECG) and echocardiography, with echocardiography recognized as the gold standard for the assessment of LVH. This imaging modality determines the presence of LVH by evaluating the left ventricular mass index (LVMI). For diagnostic purposes, LVH is defined in males as a left ventricular mass index greater than 115 g/m² and in females as greater than 95 g/m². Despite the high accuracy of echocardiography in diagnosing LVH, access to this examination is not universal across all healthcare facilities. Consequently, electrocardiography, a widely available, non-invasive, and cost-effective diagnostic tool, serves as an alternative for the diagnosis of LVH. Several criteria exist for the electrocardiographic assessment of LVH, including the Sokolow-Lyon and Cornell voltage criteria. However, the sensitivity of these electrocardiographic methods remains relatively low, with reported sensitivities of 17% for the Sokolow-Lyon criteria and 35% for the Cornell criteria. In left ventricular hypertrophy, the interstitium experiences changes characterized by fibrosis and other deposits. These alterations can reduce the expression of hypertrophic myocardial tension and limit the diagnostic capabilities of surface electrocardiograms. Additionally, several factors influence electrical tension, including variations in chest wall thickness, heart muscle activity, the distance of the electrode from the left ventricle, and lung activity. The presence of these limiting factors can increase the rate of false negatives in diagnosis. In 2017, Peguero and Lo Presti introduced novel criteria for the diagnosis of LVH, defined by evaluating the deepest S wave and summing it with the S wave in lead V4. According to these new criteria, LVH is identified as ≥ 2.8 mV in men and ≥ 2.3 mV in women. The Peguero-Lo Presti criteria demonstrate improved sensitivity when compared to traditional criteria such as Sokolow-Lyon and Cornell, offering enhanced diagnostic accuracy.

Plant growth regulators are organic or synthetic compounds that function to regulate and stimulate plant growth, both in the vegetative and generative phases. The administration of plant growth regulators (PGRs) is an effort to provide hormones to plants for optimal growth. The purpose of this study was to determine the growth and yield of expired corn (Zea mays L.) plants after the administration of various plant growth regulators. The research using a randomized block design consisted of 10 treatments where treatment A = new seeds + Aquades, B = new seeds + 500 cc / L ZPT bean sprout extract, C = new seeds + 500cc / L ZPT young coconut water, D = new seeds + 0.2 cc / L Auxin, E = new seeds + 0.2 cc / L Gibberellin, F = expired seeds + Aquades, G = expired seeds + 500 cc / L ZPT bean sprout extract, H = expired seeds + 500 cc / L young coconut water, I = expired seeds + 0.2 cc / L Auxin, J = expired seeds + 0.2 cc / l Gibberellin. Each treatment was repeated 3 times, until 30 experimental units were obtained. Based on the results of the study, the highest plants were found in treatment I = expired seeds + 0.2 cc / L auxin at plant age 6 MST with an average of 257,667. The observation of the highest number of leaves was found in treatment I = expired seeds + 0.2 cc / L auxin at plant age 6 MST with an average of 14,530 strands, the best stem diameter was in treatment F = expired seeds + Aquades, at plant age 5 MST with an average stem diameter of 28,733, observations on the weight of the cob with husk and the best weight of the cob without husk were found in treatment F = expired seeds + Aquades with an average of 287,200 grams, and 251,533 grams, observations on the length of the best cob in treatment F = expired seeds + Aquades with an average length of 19,900 cm.

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.

The distribution of inheritance is an important issue in Indonesian society which adheres to a plural legal system, namely Islamic law, customary law, and western civil law. One of the issues that often raises differences of opinion is the position of biological children and adopted children as heirs. In Islamic law, the right to inherit is based on the relationship of the nasab so that the biological child gets a clear share, while the adopted child does not have the right to inherit but can still be given a share through a grant or obligatory will. In contrast, Toba Batak customary law emphasizes the patrilineal principle, whereby sons, including legitimate adopted children through mangain customary ceremonies, are positioned as the successors of the clan and are entitled to inheritance except hereditary inheritance. This study uses a literature study method by examining literature related to Islamic law and Batak Toba customary law and qualitatively analyzed. The results of the study show that the difference in principles between these two legal systems gives birth to social and legal conflicts in the Batak Muslim society, especially when religious and customary values must be carried out together. However, opportunities for harmonization remain open through the application of the principle of justice that recognizes the position of adopted children in customary structures, as well as upholding sharia by granting rights through the mechanism of compulsory wills. These findings emphasize the need for an integrative approach in resolving inheritance disputes in order to create legal certainty, social justice, and maintain cultural and religious harmony.

This study aimed to evaluate the effect of broiler concentrate-based rations combined with corn and rice bran on the performance of native chickens. A total of four dietary treatments were formulated, namely P1 (100% broiler concentrate), P2 (75% broiler concentrate, 10% corn, 15% rice bran), P3 (50% broiler concentrate, 30% corn, 20% rice bran), and P4 (25% broiler concentrate, 55% corn, 20% rice bran). The parameters observed included feed intake, body weight gain, and feed conversion ratio (FCR). Data were analyzed using analysis of variance (ANOVA), and significant differences among treatments were further tested with Duncan’s New Multiple Range Test (DMRT). The results showed that dietary treatments significantly affected the growth performance of native chickens (P<0.05). Chickens fed diets with higher proportions of broiler concentrate (P1 and P2) exhibited better body weight gain and more efficient feed conversion compared to those receiving lower concentrate levels (P3 and P4). In contrast, increasing corn and rice bran levels tended to increase feed intake but did not proportionally improve body weight gain, resulting in poorer FCR. It can be concluded that native chickens perform optimally when fed rations containing at least 75% broiler concentrate, which provides a balance between growth and feed efficiency.

The research aims to determine red onion plants' growth and production response (Allium cepa L.) on Planting Distance Treatment and Eco enzyme Concentration. This study used a Randomized Block Design (RBD) with two treatment factors. The first factor is the Planting Distance treatment consisting of 3 levels, namely J1 = 15 cm x 15 cm, J2 = 20 cm x 15 cm, and J3 = 25 cm x 15 cm. The second factor is the Eco enzyme Concentration, consisting of 3 levels, namely E1 = 0.8 ml ee / 240 ml water, E2 = 1.6 ml ee / 240 ml water, and E3 = 2.4 ml ee / 240 ml water. The study results showed that the Planting Distance treatment significantly affected root length and tuber diameter per sample. However, they had no significant effect on fresh tuber weight on the growth and production of shallots. The Eco enzyme concentration treatment had no significant effect on all observation treatments. The interaction between Planting Distance and the Eco enzyme concentration had no significant effect on all observation treatments.

This study aims to describe the ethnomathematics activities carried out by corn farmers in Tegal Arum Village. The approach used is qualitative with an ethnographic method, with data collected through observations, in-depth interviews, and documentation from two farmers who are knowledgeable in traditional corn farming practices. The main focus of this study is to identify the application of basic mathematical concepts, such as counting, measuring, and calculating, in their daily farming activities. The results show that the farmers in Tegal Arum Village apply mathematics in a contextual form, derived from experiences and practices passed down through generations. For example, they calculate the seed requirements, estimate the number of laborers and planting time, and measure the harvest using local units like sacks and handfuls. These activities reflect the relevant application of ethnomathematics, which can be integrated into contextual mathematics learning in schools. The findings indicate that mathematics is not only taught in a formal setting in schools but also naturally develops in the community's daily life, especially through farming activities. Therefore, the results of this study are expected to serve as a reference in the development of a local culture-based curriculum that connects mathematics learning to real-life contexts.
