The research aimed to intend the best treatment for each treatment of watering volume and Growing design on the productivity and quality of cherry tomato cultivar Ruby. The study is an experimental exploration using RCBD factorial. The treatment factors include: Growing Design (greenhouse, Rain shelter, Screen house) and Watering Volume (100% Etc, 75% ETc, 50% ETc). The result showed that root dry weight and root-shoot ratio were found higher in the screen house design, while fruit firmness was higher in the rain shelter design. Considering the effect of watering volume, higher fruit diameter, heavier fruit, fruits per plant, ultimate fruit & biological yield per plant, higher root & shoot biomass, root-shoot ratio, leaf chlorophyll content, greater fruit skin firmness and elasticity was noted in the 100% ETc treatment. In contrast, the growth rat...

Hybrid genotypes have been found to be superior in terms of seed yield to their parental lines. This research intended to develop high-yielding cultivars to evaluate the comparative study for physiological, morphological and qualitative traits of sunflower hybrids. Data of various growth, developmental, agronomic and yield traits were recorded to quantify the response. Analysis of variance showed that the hybrids were significant in all the traits, except for head and stem diameters. The results regarding plant growth and yield characteristics showed that maximum achene yield 3444.3 kg ha-1was noted for the Hysun33, while the minimum value of achene yield was noted for the SMH-1003 with plant height 1816 kg ha-1. The maximum stem girth was found for the SMH-1104 with the 25.43 cm, while the lowest value for the stem girth 19.7 cm was found for the SMH1001. T...

According to the Internal Quality Audit results at Siliwangi University in 2020, two-thirds of the time, assigned lectures are available for students to listen to the material. Such situations are consistent with the findings of (Cohen, 1996; Ghaed et al., 2018), which state that "hearing plays an essential part in communication, taking up 40-50% of the total time spent on communicating, speaking 25-30%, reading 11-16%, and writing approximately 9%." Even though listening activities account for most communication, few people are concerned with developing their listening abilities. Many believe listening is simple since it needs passive action, even though (Idrissova et al., 2015). The term "passive skill" when used for listening is misleading. This misperception may originate from the fact that learners appear to sit silently in the language lab, listen to pre-recorded conversations, and write responses to the same questions as the oral stimulus. Therefore listening teaching has gotten much attention. Listening is an active and interpretative process. The message is formed in the interactional space between participants rather than fixed (Hue, 2019; Idrissova et al., 2015). (Idrissova et al., 2015) described complicated listening activities and how the hearing comprehension process comprises three sequential steps: receiving, attending, and comprehending. Responding and remembering may follow comprehending since listeners may reply immediately or remember the message to respond later. Each level of the listening process involves significant mental efforts. Very obvious in the phases of attendance and comprehension (including responding and remembering). At the attending stage, the listener must concentrate on the subject matter contained in the language's linguistically organized and integrated sounds. Listeners must consider interpreting, assessing, and reacting correctly to the conversation's substance during the comprehension stage. Listeners must have a clear mind during the remembering stage to recall all of the conversation's details. The sophistication of listening actions, as stated by ABSTRACT The purpose of this study is to investigate a logical-based learning order and its effects on the growth of pupils lecturing the listening skill. The first approach employed in this study is R&D. Furthermore, data was gathered through inspection, observation, and interviews. The study was conducted for students in the first semester of the 2021/2022 academic year at Siliwangi University Tasikmalaya's Faculty of Teacher Training and Education. The information was quantitatively processed. The findings revealed that logic-based learning syntax positively influenced student lecturing and listening skills. It is advised that the research be followed up and confirmed by people in the same profession to stretcher the research results.

The role of agricultural extension workers is to help increase food production and development. Counseling in Culamega District, Tasikmalaya Regency, was carried out by PNS extension workers, THL (Freelance) extension workers, and self-help extension workers. One of the supporters of increasing the performance or development of organic tea farmers in Culamega District is that independent extension workers are responsible for helping extension workers and farmers to strengthen the relationship between extension workers and farmers. From land cultivation to processing results, organic tea is a tea plant that uses organic ingredients without mixing chemicals or pesticides. Fertilization uses fertilizer based on goat manure, roasted husks, and liquid organic fertilizer. This study aimed to determine the effect of the role of independent extension workers on the development of organic products in Ci...

This study sought to identify the most effective watering volume and growing design treatment for the production and quality of the cherry tomato cultivar Ruby. This study was an exploration using a factorial experiment with an RCBD design. The treatment factors included the growing design (greenhouse, rain shelter, and screen house) and the watering volume (100% ETc, 75% ETc, and 50% ETc). The results showed that the root dry weight and root–shoot ratio were higher in the screen house design, while the fruit firmness was higher in the rain shelter design. Considering the effect of the watering volume, a higher fruit diameter, heavier fruits, more fruits per plant, higher ultimate fruit and biological yield per plant, higher root and shoot biomass, better root–shoot ratio, higher leaf chlorophyll content, greater fruit skin firmness, and greate...

This research was conducted to determine farmers' preferences in choosing large red chilies and cayenne peppers. The method used in this research is the conjoint analysis of 36 respondents. The research results in choosing large red chili and cayenne pepper commodities are resistant to pests, diseases, and market prospects. Furthermore, regarding the combination of attribute levels, the utility estimate value between the two commodities has a different value. Pearson and Kendall's correlation test results for cayenne pepper are less than 0.05 compared to large red chili. The farmers prefer cayenne pepper to pests, longer plant life, higher market selling prices, lower input prices, and easier access to seeds than large red chilies.

The quality of nutmeg seed rapidly declines so that it can affect the productivity of both the seed and its production. This study aims to determine the effect of the storage period and the type of packaging for the storage of nutmeg seeds. Method: This study used a factorial complete block design with the type of packaging factor in several storage periods. Treatment Types of Packaging (K) consisted of four types, namely plastic standing pouch packaging with a size of 14 x 20 cm with a thickness of 0.10 mm (K1), plastic sack packaging which was converted to a size of 17 x 21 cm with a thickness of 0.10 mm (K2), a burlap sack packaging which was converted to a size of 14.5 x 20 cm thickness 0,20 mm (K3), and a rectangular jar measuring 12 x 19 cm thickness 0,20 mm (K4). The storage period was carried out for 12 days (P1), 18 days (P2) and 24 days (P3). The experiment was carried out in room conditions with an average temperature of 28.910C and RH 61.17%. Result: The results showed that storage of nutmeg seeds for 12 days in plastic standing pouch packaging was able to maintain the viability of nutmeg seeds. Storage like this produces seeds with germination capacity (56.25%), moisture content (48.42%), respiration rate (32.35 mmCO2/kg/hour), growth speed (10.5%/etmal), vigor index (9.73) and seed germination capacity. 55.00. Conclusion: Nutmeg seeds should be sown immediately after download. However, with certain storage techniques, nutmeg seeds can still survive with good quality at 12 days of storage in standing pouch packaging with zeolite.
