PENGARUH FAKTOR LINGKUNGAN TERHADAP MUTU DAUN DAN DINAMIKA HARGA TEMBAKAU MADURA TAHUN 2021–2025

2026-03-03T06:34:49+00:00

Fluctuations in tobacco quality and price represent a major challenge in local tobacco agribusiness, particularly in regions where production is highly sensitive to environmental variability such as Madura, Indonesia. Variations in agroclimatic conditions can influence the chemical characteristics of tobacco leaves, which in turn affect grading and price formation at the farmer level. This study aims to examine the effects of environmental factors on tobacco leaf quality and to analyze their implications for the price dynamics of Madura tobacco during the 2020–2025 observation period. The research employs a quantitative approach using a field case study involving 30 tobacco farmers in Pamekasan Regency. Environmental variables include rainfall and harvest temperature, while leaf quality is measured using three indicators: moisture content, nicotine content, and reducing sugar. Data are analyzed using descriptive statistics, trend analysis, and multiple linear regression models to estimate the influence of environmental factors on leaf quality and the effect of quality on tobacco prices. The results show that rainfall and harvest temperature significantly affect leaf quality indicators (p < 0.05). Higher rainfall increases leaf moisture content (? = +0.42) and decreases nicotine (? = ?0.38) and reducing sugar (? = ?0.31), while higher harvest temperature decreases moisture content (? = ?0.29) and increases nicotine (? = +0.41) and reducing sugar (? = +0.35). Furthermore, leaf quality significantly influences tobacco prices at the farmer level, with nicotine showing the strongest positive effect (? = +0.52; p = 0.001), while moisture content has a negative effect (? = ?0.36; p = 0.012). Quality variations explain approximately 67% of price variation (R² = 0.67). These findings indicate that environmental variability affects tobacco prices indirectly through changes in leaf quality. The study contributes to the agribusiness literature by empirically demonstrating the environment–quality–price linkage in smallholder tobacco production systems and provides an analytical basis for improving tobacco competitiveness through environmental adaptation, postharvest quality management, and greater transparency in grading systems.

Pepper (Piper ningrum L.) is a strategic spice crop in global trade. Two types of pepper are commonly traded in both domestic and international markets: white pepper and black pepper. Sambas Regency is one of the pepper centers in West Kalimantan Province. Sumber Harapan Village is one of the pepper-producing villages in Sambas Regency. Some residents of Sumber Harapan Village have pepper, but the pepper production is not as abundant as in other areas. The pepper produced by the Sumber Harapan Village community is divided into two types: black pepper and white pepper. This study used a quantitative research method, using a total sampling method with 16 respondents. This study aimed to compare the production levels of black pepper and white pepper in Sumber Harapan Village. The results of this study indicate that the ratio of black pepper to white pepper production in Sumber Harapan Village in 2023 was 1:9, meaning that for every 1 kg of black pepper, there are approximately 9 kg of white pepper. The ratio of black pepper to white pepper production in Sumber Harapan Village in 2024 was 1:7, meaning that if a farmer produces 1 kg of black pepper, they will also produce 7 kg of white pepper. Keywords: Black Pepper and White Pepper, Comparison, Production Level.

EFEKTIFITAS KONSENTRASI DAN LAMA PERENDAMAN GIBERELIN TERHADAP PERKECAMBAHAN TIGA VARIETAS TRUE SHALLOT SEED

2026-04-13T10:01:04+00:00

This study aimed to determine the optimal gibberellin concentration and soaking duration to enhance the germination of three shallot varieties derived from True Shallot Seed (TSS). The research was conducted from October to November 2025 in Triyagan Village, Mojolaban District, Sukoharjo Regency, Central Java. A Randomized Complete Block Design (RCBD) was employed with three treatment factors: gibberellin concentration, soaking duration, and variety. Observed variables included germination percentage, germination speed, seedling height, root length, and number of leaves. The results indicated that the variety factor significantly influenced all observed variables. Gibberellin treatment independently had a significant effect on all variables except root length. Soaking duration significantly affected germination and seedling height. Furthermore, a significant interaction was observed between variety and gibberellin on seedling height and leaf number, as well as an interaction between gibberellin and soaking duration on germination percentage. The application of 150 ppm gibberellin with a 12-hour soaking duration proved to be the most effective combination for improving the TSS germination across the three shallot varieties.

DAMPAK CURAH HUJAN, SUHU DAN KELEMBABAN PADA PERTUMBUHAN TEBU (SACCHARUM OFFICINARUM L.) VARIETAS BULULAWANG

Sugarcane growth and yield are influenced by the interaction between plant factors, soil conditions, climate, and cultivation practices. Climate is an uncontrollable component, so it is an important aspect that must be carefully considered in sugarcane cultivation activities. Three important variables are rainfall, humidity, and temperature, and to date, research related to the relationship between climate variables and sugarcane growth has not been widely conducted. This study aims to determine the relationship between sugarcane growth and climate conditions (rainfall, humidity, and air temperature). This study used three locations: Magelang, Purworejo, and Kulon Progo, in sugarcane areas with the Bululawang variety and plant age. The observed plant growth variables included stem height, stem diameter, number of leaves, number of stems per clump, and number of sugarcane internodes in each field. Meanwhile, the observed climate variables were rainfall, temperature, and humidity (obtained from BMKG). Data analysis was carried out using descriptive quantitative data and a person correlation test using Excel. The results showed that Magelang had the highest rainfall and Kulon Progo had the lowest rainfall. The air temperature in Purworejo was the highest and Kulon Progo had the lowest. The highest humidity is in Purworejo and the lowest humidity is in Magelang. Rainfall has a significant correlation with sugarcane growth, while temperature and humidity have a correlation but are not significant. Rainfall has a very strong and significant correlation with stem diameter (r = -0.835), number of internodes (r = -0.857), and number of stems per clump (r = -0.897). Air temperature and air humidity have a very low and insignificant correlation with all plant growth variables. This indicates that rainfall is the most important climate factor influencing sugarcane growth.

RESPON HASIL 2 VARIETAS TANAMAN KACANG TANAH (Arachis hypogaea L.) DALAM PENGAPLIKASIAN PGPR AKAR PUTRI MALU (Mimosa pudica L.)

The cause of the decline in peanut production is due to insufficient nutrients in the soil. The solution is to use PGPR (plant growth promoting rhizobacteria) biofertilizer from the roots of the sensitive plant, which contains a group of bacteria that can improve the availability of nitrogen and phosphate. In addition, the use of superior varieties is also an important factor in increasing peanut yields. The objective is to measure the concentration of PGPR in mimosa root that is suitable for increasing the yield of two peanut varieties. The implementation will take place from July to December 2025 in Patemon Village, Pakusari District, Jember Regency, East Java. A factorial randomized block design (RAK) with two treatment factors will be applied. The first factor is the peanut variety, namely: Katana 2 and Tala 1 varieties, while the second factor is the concentration of PGPR in mimosa pudica roots, namely: PGPR 0 ml/l (Control), PGPR 25 ml/l, PGPR 50 ml/l, and PGPR 75 ml/l. The results showed that the variety had a significant effect on the parameters of the number of pods and the weight of 100 seeds. In the treatment of PGPR root hair, the best concentration was PGPR 25 ml/l, which had a significant effect on the parameters of wet pod weight per plot and the weight of 100 seeds. Meanwhile, the interaction between the variety and PGPR showed no effect on all observation parameters.

2026-04-20T02:49:46+00:00

This study aims to determine the abundance and diversity of insects that visit the flowers of the cocoa plant (Theobroma cacao L.) based on the observation time (morning, afternoon and evening). This study was carried out from April to June 2025 in a cocoa plantation owned by farmers (cocoa plant age ? 10 years) in North Tada Village, South Tinombo District, Parigi Moutong Regency, Central Sulawesi Province. This study shows that during the morning period, approximately between 06:30 and 09:30 WITA, the highest presence or preference of insect pollinators on cacao plants was observed, accounting for 51.74% or a total of 789 individuals (N = 789; S = 9). These findings indicate that flower-visiting insects on cacao, which are predominantly pollinators (approximately 93.04%), generally exhibit peak visitation during the morning, coinciding with anthesis, as well as in the late afternoon.

This study aims to determine the optimum dosage of Nitrogen (N), Phosphorus (P), and Potassium (K) fertilizers to support the growth of Bitter Gourd (Momordica charantia L.). The experiment was conducted using a single-factor Completely Randomized Design (CRD), consisting of fertilizer dosage levels at 0%, 25%, 50%, and 75% of the recommended doses (equivalent to 5 g Urea, 4 g SP-36, and 4 g KCl per plant). Observations were made on plant height at 1 and 2 weeks after planting (WAP), number of leaves at 1 and 2 WAP, as well as fresh weight and dry weight. The results indicated that variations in N, P, and K fertilizers dosages significantly influenced all growth parameters. Generally, the treatment at 25% of the recommended dose showed the best results compared to other treatments. Quadratic regression analysis revealed that the optimum dosages for plant height at 1 WAP and 2 WAP were 25.71% (R² = 0.64) and 19.70% (R² = 0.53) of the recommended dose, respectively. The optimum dosage for number of leaves at 2 WAP was 15% (R² = 0.50), while the optimum dosages for fresh weight and dry weight were 8.5% (R² = 0.56) dan 10.38% (R² = 0.55) respectively.
