Poor soil quality and inefficient nutrient utilization remain major constraints in tomato (Solanum lycopersicum L.) cultivation, often resulting in reduced plant growth, lower productivity, and suboptimal fruit quality. This study aims to evaluate the growth performance of rose tomatoes through the integration of open-field cultivation and hydroponic planting systems. The research methods included land preparation using the Pythagorean technique to ensure proper spacing and planting layout, the application of organic fertilizers to improve soil fertility, and the transition to a hydroponic drip irrigation system using rockwool as the growing medium during weeks 1 to 7 of plant development. Plant growth parameters, including plant height, leaf development, stem vigor, and overall plant health, were observed throughout the cultivation period. The results indicated that the combination of appropriate soil management practices and precise nutrient delivery in the hydroponic system significantly enhanced nutrient uptake and supported healthy plant growth. Furthermore, the drip irrigation system helped optimize water use efficiency while reducing nutrient losses. This integrated cultivation approach demonstrated its potential as an effective solution for maintaining crop quality and productivity, particularly in areas with limited land resources. Overall, the findings suggest that integrated management practices can provide a practical, efficient, and sustainable strategy for farmers seeking to improve horticultural production in modern agricultural systems.

This study aims to analyze the effect of combining bait types and immersion durations on the catch yields of blue swimming crabs (Portunus pelagicus) in the waters of Kuala Penet, East Lampung. The research method employed was a field experiment utilizing a factorial Completely Randomized Design (CRD). The focus of the study was directed toward two types of bait, namely goldstripe sardine (Sardinella spp.) and chicken intestines, with three variations of immersion duration: 6 hours, 12 hours, 18 hours, and 24 hours. Through statistical analysis, it was discovered that the combination of goldstripe sardine bait and a 6-hour immersion duration provided the most optimal catch yields. Nevertheless, chicken intestines demonstrated strong potential as an economical and sustainable alternative bait at a 12-hour immersion duration. The interaction between the bait type and immersion duration variables proved to be significant, thereby supporting an integrated approach to the management of collapsible pots. These findings provide a scientific basis for formulating sustainable crab fishing guidelines that can be adopted by local fishermen and relevant authorities to support the ecosystem-based conservation of coastal fishery resources in East Lampung.

Indonesia is a large archipelagic country with significant fisheries potential. However, fish resources in Indonesian waters have shown a declining trend over the past decade. This decline is caused by various factors, including the deterioration of coastal environmental quality due to human activities that pollute the sea, destructive fishing practices, and excessive exploitation or overfishing. This study aims to analyze the utilization rate of bigeye tuna in FMA-NRI 573 landed at PPS Nizam Zachman and to provide recommendations for the utilization efforts of bigeye tuna in FMA-NRI 573 landed at PPS Nizam Zachman. The utilization rate of fish can be calculated by comparing the total catch to the maxmimum sustainable yield (CMSY) using the formula TPc=(Ci/CMSY)×100%TP_c = (C_i / C_{MSY}) \times 100\%TPc=(Ci/CMSY)×100%. The utilization rate obtained, with an average CMSY of 846,325, falls under the category of Lightly Exploited according to FAO and Moderately Exploited based on Ministerial Regulation KP No. 22/2021. This indicates that the utilization is still relatively low or minimal. Therefore, it is necessary to conduct a review of existing fishing regulations in order to maintain the potential sustainability of capture fisheries.

Rainfall potential analysis plays a critical role in the management of air resources, mitigation of hydrometeorological disasters, and agricultural activity planning. Accurate estimation of rainfall patterns is essential to ensure effective decision-making in irrigation systems, water resource management, and disaster risk reduction strategies. This study aims to model the probability of rainfall occurrence using a statistical approach based on historical data obtained from the Bureau of Meteorology. The data spans a multi-year period and captures seasonal and regional variability in rainfall events. To characterize rainfall patterns, various probability distributions are tested, including the exponential distribution and the Weibull distribution, which are commonly applied in hydrological studies. Furthermore, the Markov chain method is employed to assess the likelihood of rainfall occurrence on a given day based on the conditions of the preceding day, thereby capturing temporal dependencies. Parameter estimation is conducted using Maximum Likelihood Estimation (MLE), a robust statistical method that enhances the precision of the model. The suitability of each probability distribution in representing the observed rainfall data is evaluated through goodness-of-fit tests such as the Kolmogorov-Smirnov test. The findings reveal that certain distributions align more closely with the local rainfall characteristics, demonstrating the importance of regional analysis in climate modeling. The combination of probabilistic modeling, Markov analysis, and rigorous statistical testing provides a reliable framework for forecasting rainfall. These results are expected to serve as a scientific basis for stakeholders in agriculture, environmental planning, and disaster preparedness, offering insights that support sustainable water resource utilization and risk management.
