Abstract

In the last few decades, women in Sri Lanka still face social inequality. This paper highlights that patriarchy as a socio-cultural factor is very dominant in gender discrimination in the country. Among them is the role of religion which has created the root of male tendency to dominance. As a result, women become a marginalized group, including in politics and work. This disparity has in fact been rooted from the family level, where the role of women in various matters in this small scope is very limited.

Abstract

This study aims to evaluate the role of the Rantau Asem Village Government in village development. A qualitative descriptive method was employed using observation, in-depth interviews, and literature review as data collection techniques. The study was grounded in role theory and the concept of village development. The Rantau Asem Village Government has fulfilled its role as an innovator by creating village development programs in an easily understandable language and encouraging community participation. exclamation As a motivator, the village government has fostered and maintained development dynamics by designing programs aligned with community aspirations. As a facilitator, the village government has facilitated the implementation of development projects and bridged various community interests. Nevertheless, there are still areas for improvement, such as enhancing human resource capabilities and skills. Additionally, the village government needs to adopt an appropriate approach to address community aspirations to boost community participation in village development.

Abstract

Vascular streak dieback is a major disease in cocoa trees that affects at in various stages, and effect in significant yield losses. This study aimed to identify the area under the disease progress curve (AUDPC), infection rate (r), and the influence of weather factors on the development of vascular streak dieback disease caused by Ceratobasidium theobromae in some cocoa clones with different resistant levels. The research used a randomized complete block design consisted six clones as treatment and each treatment consisted of three replications. Disease severity was observed on six different cocoa clones and observations were conducted monthly. The observation of disease severity was observed monthly for 12 months and then used to analyze AUDPC and infection rate. Monthly data on the weather conditions were taken from the climatology station of the Indonesian Coffee and Cocoa Research Center, East Java. The results showed that Sulawesi 01 and ICCRI 09, categorized as resistant clones, showed low AUDPC values, 0.02 and 2.85 respectively. The cocoa clones Sulawesi 02 and MCC 02, categorized as tolerant clones, had higher AUDPC values, 19.87 and 34.27 respectively. The cocoa clones BCL and BL 50 showed the highest AUDPC values, 277.05 and 265.70 respectively. Path analysis on resistant clones indicated that rainfall is the most influential weather factor in increasing the severity of vascular streak dieback, followed by temperature. Higher relative humidity can significantly reduce disease severity, while sunlight and wind speed have smaller effects. In contrast, path analysis on susceptible clones showed that temperature, rainfall, relative humidity, and wind speed all positively influence the severity of vascular streak dieback. At the same time, sunlight has a mitigating effect.

Abstract

Vascular streak dieback (VSD) is one of the main diseases on cocoa that can cause a decrease in production and even death on susceptible plants. The use of selection criteria is very important in the selection process at the seedling phase, young plants and even mature plants in order to support the breeding process of resistant varieties. The aim of the study was to determine the characteristics of flush including flush color, stomata characters and duration of flush color change to green or towards mature leaves as one of the selection indicators for VSD resistance in cocoa. The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, Indonesia. Study of flush color and stomata characters was conducted using a randomized complete block design consisting of four cocoa genotypes with different levels of resistance, classified as resistant to VSD disease (Sulawesi 1, PNT 16) and as susceptible (BCL and BL 50). Each clone was repeated three times and each replication consisted of three plant samples. Flush color duration study was carried out on six cocoa genotypes as treatments, three genotypes with resistant to VSD (PNT 16, Scavina 12, Sulawesi 1) and three genotypes as susceptible to VSD (BL 50, BCL, Criollo 22). Each treatment was repeated three times and each replication consisted of three plant samples. The results showed that the resistant genotypes showed a tendency to have lower chlorophyll and anthocyanin content than the susceptible ones. The stomata character in the resistant genotypes was not different than the susceptible ones, however, the resistant genotype showed that the stomata density at flush tended to be lower. The duration of flush color change to mature leaves (green) in resistant genotypes was significantly faster than susceptible genotypes.

Abstract

Seed growth and uniformity are keys in producing high quality and yield of cocoa (Theobroma cacao L.). Plant growth is influenced by internal factors (genetics)and external factors, including planting media. This study aimed to determine the effect of cocoa planting material types and planting media of cocoa seedlings.The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute (ICCRI), Jember, Indonesia, using a split-plot group randomized design. The main plot was the planting media consisting of topsoil, topsoil and rice husk, and topsoil and manure. The subplots consisted of two types of cocoa planting material: hybrid seeds ICCRI 08H and half-sib Sulawesi 1. Each treatment was replicated three times. The results showed that the media influenced on seedling growth uniformity, plant height, stem diameter, and number of leaves. Genetic factors affect plant height and stem diameter. The interaction of media and the type of planting material affect the stem diameter and number of leaves. Cocoa seedling growth with the best plant height and stem diameter was shown in topsoil and manure media, while the response to the number of lleaves showed differences between ages and planting media used. ICCRI 08H hybrid cocoa planting material showed the highest plant height and stem diameter compared to Sulawesi 1 half-sib

Abstract

Fat and polyphenols are functional compounds in cocoa beans that determine product quality and are highly influenced by environmental factors. Informationregarding the stability of the character of the polyphenol and fat content of the cocoa plant is still limited, therefore it needs further study. This study aimed todetermine the stability of fat and polyphenol content in several cocoa clones at three different growing locations. The study used a nested design with a randomized block design with field design consisting of five cocoa clones, three different growing locations and each combnation treatment was repeated three times. The cocoa clones used were ICCRI 09, MCC 02, Sulawesi 1, KW 516, and KW 562, planted in three different growing locations namely, Kaliwining Experimental Station, Jember, East Java; Sekampung Udik, East Lampung, Lampung; and Harapan Jaya, Pesawaran, Lampung. The combined analysis of variance indicated that there was a genetic interaction with the environment for the character of fat and polyphenol content. Based on the stability analysis, it is known that all cocoa clones fall into the stable category according to the concept of static stability. Furthermore, based on addtive main effect and multiplicative interaction (AMMI) analysis, the clones that can be recommended for Jember, East Lampung and Pesawaran locations for the character of fat content are clone KW 516, while for the characters of high and stable polyphenol levels at the three locations are clones MCC 02, KW 516, and KW 562. In addition, the most recommended clone based on fat content at Jember was the MCC 02 clone, KW 562 at East Lampung, and KW 516 clone at Pesawaran. The existence of the phenomenon of genetic interaction and the growing environment for the characters of fat and polyphenols in cocoa plants provides important information, especially in considering the development of cocoa for specific purposes, namely parameters of fat and polyphenols.

Abstract

Improving students' academic performance is a key goal in the context of higher education. However, the process of identifying students who require additional support is often complicated and complex. Traditional approaches in analyzing student performance data tend to be limited in handling data uncertainty and complexity. Therefore, the development of fuzzy logic-based decision-making systems is becoming increasingly important. This research aims to develop a fuzzy logic-based decision-making system to predict student performance accurately and efficiently. This approach utilizes fuzzy logic concepts to handle uncertainty and complexity in data, and allows the integration of various input factors, such as exam results, class participation, and other variables, in the decision-making process. The research methods include collecting historical student performance data, modeling fuzzy variables for inputs and outputs, developing fuzzy inference rules, and implementing and testing the system using split test data. Numerical example results show that the system is able to provide predictions of student performance by considering relevant input variables. In addition, the system also offers the potential to improve the efficiency of educational interventions by identifying at-risk students faster and more precisely. As such, the development of this fuzzy logic-based decision-making system is expected to make a significant contribution to efforts to improve the quality and equity of higher education by ensuring that every student gets the support they need to reach their full academic potential.
