Abstract

This study was to examine the effect of changes in digestive tract that is seen from the length of the small intestine size of broiler chickens given kefir. The study used 200 MB of broiler DOC as many as 200 animals which were kept randomly in a cage plot. The study was conducted for 5 weeks with 4 treatments and repeated 5 times so that the number of experimental units was 20 units. The treatments to be tested were: T0 = basal ration (control), T1 = basal ration + 1.5% probiotic, T2 = basal ration + 3% probiotic, T3 = basal ration + 4.5%. Kefir used was derived from goat milk which was given 10% kefir grain fermented for 48 hours. The data obtained were analyzed for variance based on a completely randomized design and continued using duncan test. The results showed that the final body weight was significantly different (P <0.05), while the feed efficiency, relative length of duodenum, jejunum, ileum, overall small intestine and cecum had no significant effect (P> 0.05). The conclusion that the administration of probiotics in the form of kefir has no significant effect on the relative length of the small intestine and cecum, but has a significant effect on final body weight. The use of kefir needs to be considered in terms of cost because it uses milk as a fermentation media.

Abstract

Chlorophyll-a in waters is one of the important factors that determines the primary productivity/fertility of waters. Chlorophyll-a measurements can be carried out in two ways, namely conventionally by direct measurements in the field and modernly by using remote sensing technology. The aim of this research is to determine variations in the distribution of chlorophyll-a in the waters of the Ombai Strait. The data used in this research is monthly level 3 climatology data from 2003–2022 from the Aqua-MODIS (Moderate-Resolution Imaging Spectroradiometer) satellite using a remote sensing and geographic information system approach. The results of this research were that the highest chlorophyll-a concentration was found in coastal areas and the lowest concentration was found in offshore waters. According to the monthly distribution of chlorophyll-a, the highest concentration was recorded in July with values ranging from 0.251-10.486 mg/m3 with an average of 0.566 mg/m3 and the lowest concentration was recorded in November with values ranging from 0.158-2.151 with an average of 0.427 mg/m3.

Abstract

Blorep Swamp is one of the swamps in Merauke Regency, with the status of a swamp being City Forest. Blorep Swamp is one of the swamps that has enormous potential for fish resources and can provide a decent life for the people living around Blorep Swamp. This study aims to analyze the social conditions of the community in ecosystem-based inland fisheries management (EAFM), where the indicators used include stakeholder participation. The time of the research was carried out from March to May 2023. The data collection method used observation, interview and documentation techniques. The results showed that the social condition of the community in the management of Blorep Swamp on the stakeholder indicator was at a low status, this was because the existence of Blorep Swamp could be said to be very secretive which resulted in several government agencies not knowing the existence of the swamp. Meanwhile, the indicators of fisheries conflict and utilization of local knowledge are in good status.

Abstract

The presence of weeds is a significant factor that contributes to the decline in maize yield. To reduce yield loss, appropriate weed control methods must be applied. The first step in determining these methods is to identify weed dominance and diversity. This study aims to identify the dominance and diversity of weeds in three corn planting systems: conventional, jajar legowo 1:2, and 1:3 spacing. The research was conducted at the Teaching Farm Polinela Organic Farm in Lampung Province from November to December 2023. Vegetation analysis was performed using a 0.5 m2 quadrant randomly placed on 10 plots of land. The dominance value of weeds was determined using the Summed Dominance Ratio (SDR) value, while the diversity of weeds was measured using the Shanon-Wiener index value (H'). The study found that the conventional field had 9 weed species, the 1:2 legowo field had 8 weed species, and the 1:3 legowo field had 5 weed species. Ageratum conyzoides was the dominant broadleaf weed species in both the conventional corn field and jajar legowo 1:2, while Asystasia gangetica dominated the jajar legowo 1:3 corn field. The weed diversity index analysis results for the three corn planting systems fall into the medium category. Specifically, the results are 2.12 for conventional corn fields, 1.94 for 1:2 jajar legowo corn fields, and 1.3 for 1:3 jajar legowo corn fields.
