This study aimed to determine the yield potential, yield components, and morphophysiology of several red rice genotypes under upland (gogo) cultivation system. The research was conducted from August to December 2024 in Wanasaba Village, East Lombok, West Nusa Tenggara. A Randomized Completely Block Design (RCBD) was used with 12 genotypes as treatments, consisting of five lines: 19I-06-09-23-03 (G1), 21B-57-21-21-23 (G2), 23F-04-10-18-18 (G3), 23A-56-20-07-20 (G4), 23A-56-22-20-05 (G5), and 7 varieties: PBM UBB1 (G6), Danau Gaung (G7), Inpago 8 (G8), Inpago 12 (G9), Rindang (G10), Inpago Unram I (G11), and Beak Ganggas (G12), each replicated three times. The observed parameters including: relative leaf water content, chlorophyll content, number of days to flowering, number of days to harvesting, plant height, flag leaf length, total tiller number, productive tiller number, non-productive tiller number, panicle length, number of filled grains per panicle, number of unfilled grains per panicle, 1000-grain weight, weight of filled grains per clump, and yield per hectare. The data were analyzed using Analysis of Variance (ANOVA) at a 5% significance level. If significant differences were found, Duncan’s Multiple Range Test (DMRT) at the 5% level was conducted. The results of this study showed that red rice grown under upland conditions exhibited diverse yield potentials, yield components, and morphophysiological characteristics, except for traits such as number of days to flowering, leaf chlorophyll content, relative leaf water content, number of non-productive tillers, and number of empty grains per panicle. The highest yields were obtained on genotypes G4 (line 23A-56-20-07-20), G12 (Beak Ganggas), and G10 (Rindang), with yields of 5,81, 5,78, and 5,61 ton/ha respectively. Genotypes G4 and R have early harvest age, relatively moderate plant height, moderate number of productive tillers, moderate panicles, large number of filled grains with high weight of filled grains, namely G4 (36,30 grams) and R (35,10 grams). While BG (Beak Ganggas) has long panicles, large number of filled grains with high weight of filled grains, namely G4 (3605 grams), although the number of productive tillers is small.

West Lombok Regency. Using the Vector Geoprocessing method, the study processes and analyzes spatial GIS data, focusing on graphical data (geometry) and attributes (identity) through ArcMap Desktop. The main analysis techniques used include overlay analysis and buffer analysis, which are very important for spatial data analysis in GIS. This study uses mangrove distribution data from 1996-2021 which is analyzed to obtain the distribution of mangroves in the desired area. In Lembar District, there are four villages that have mangrove ecosystems, namely Eyat Mayang, Labuan Tereng, Lembar & South Lembar villages. In each village from year to year there is a change in area. The mangrove ecosystem in Lembar District from year to year has experienced an overall reduction starting from 1996-2021, experiencing a decrease of approximately 69%, namely from an area of 186 Ha to 59 Ha. However, there is one village that experienced an increase in mangrove ecosystems in 2016-2021, namely an increase of approximately 3 Ha. This cannot be separated from internal and external factors that occur so that they have an impact on changes in the mangrove ecosystem in an area. The factor that most influences changes in the area of mangroves is the existence of development in the area so that it has an impact on the mangrove ecosystem.

Karsinoma Nasofaring, Review

2025-02-15T09:54:50+08:00

Nasopharyngeal carcinoma is a malignancy that arises due to abnormal growth of body cells that appear in the nasopharyngeal area, namely the area above the throat and behind the nose. Almost 60% of malignant tumors of the head and neck are nasopharyngeal carcinomas, followed by malignant tumors of the nose and paranasal sinuses (18%), larynx (16%), and oral cavity tumors. Nasopharyngeal carcinoma is endemic in certain regions of the world, especially in Southeast Asia, and has a poor prognosis, with the highest incidence in southern China. Indonesia is one of the countries with a high prevalence of nasopharyngeal cancer patients. The average prevalence recorded is 6.2 cases per 100,000 Indonesian population with 13,000 new cases of nasopharyngeal carcinoma each year.

Falx Meningioma, Case Report dan Review

2025-01-31T15:43:53+08:00

Meningioma are tumors of the central nervous system that originate in the meninges and spinal cord. It is a benign, slow-growing neoplasm thought to originate from meningothelial cells. Meningiomas are usually oval lesions attached to the dura mater. Meningioma are most commonly located supratentorial to the calvaria or base of the meninges. Meningiomas can also be found in the tentorium, intraventricular or in the cerebellopontine position. Meningioma arise from meningothelial cap cells that are normally distributed through the arachnoid trabeculation. The greatest concentration of meningothelial cells is found in the arachnoid villi in the dural sinus, cranial nerve foramina, middle cranial fossa, and cribriform plate. Furthermore, meningiomas are commonly found over the convexity, along the falx, and at the base of the skull.

Kajian Pengaruh Suhu Pemanasan Awal Dan Waktu Sokletasi Terhadap Perolehan Minyak Biji Kelor (Moringa Oleifera Lam.)

Sound healing, or commonly referred to as music therapy using Acoustic Sound for Wellbeing (ASW) Moringa seed oil (Moringa oleifera Lam.) has significant potential for use in various industrial sectors, including food, pharmaceuticals, and cosmetics. One of the critical factors influencing oil extraction efficiency is preheating treatment and extraction process duration. This study aims to evaluate the effect of varying preheating temperatures and Soxhlet extraction times on the yield of Moringa seed oil, as well as to determine the most optimal extraction conditions. The extraction process was conducted using the Soxhlet method with n-hexane as the solvent. Preheating temperatures used in this study ranged from room temperature to 50°C, 60°C, and 70°C, with extraction times of 2, 4, and 6 hours. The results showed that preheating treatment on moringa seeds and extraction duration had a significant impact on oil yield. The optimal conditions were achieved at a preheating temperature of 70°C with an extraction time of 6 hours, yielding the highest oil recovery of 41.74%.
