The addition of organic matter to the soil planting medium and spraying ZPT bean sprout extract are some efforts to increase the supply of nutrients and overcome flower fall. This study aimed to determine the interaction between the treatment of the planting media and ZPT of bean sprout extract toward growth and yield of long bean plants. The study was conducted factorially using a completely randomized design (CRD) in 3 replications. The first factor is the type of planting medium namely M0: soil; M1: soil+ compost; M2: soil+ chaff charcoal; M3: soil+ cocopeat. The second factor was the concentration of ZPT bean sprout extract, namely T0 control; T1: 10%; T2: 20%; T3: 30%. There was a very significant interaction between the treatment of the planting media and the bean sprout extract ZPT on the variable number of pods per plant and wet weight of pods per plant. The best treatment was the combination of the type of soil and compost growing media with ZPT bean sprout extract 20%. The main effect of the type of planting media treatment showed that the results were not significantly different for all observed variables. The ZPT treatment of bean sprout extract significantly affected the variables of flowering age, harvest age, and pod length per plant, the best treatment was the concentration of ZPT bean sprout extract 20%.</em></p> Choirul Lisa Ramadhanti, Setiyono Setiyono, Gatot Subroto, Ika Purnamasari, Susan Barbara Patricia SM, Ayu Puspita Arum, Dyah Ayu Savitri Copyright (c) 2024 Journal La Lifesci Thu, 01 Feb 2024 13:59:32 +0700 Oil Issues of the Smallest Arabic Member of the OPEC <p><em>The past, current status and future of the oil sector of the UAE are considered and analyzed. The author uses methods of comparative and systematic analyses, which are implemented for assessing the emirates’ oil in the context of the world, the Middle East, and the Persian Gulf area. The article mainly concludes that the Covid-19 pandemia has seriously hit the UAE oil market (harder than the other sectors of the national economy), however, the pandemia has made inland oil demand (and petroleum imports) of the emirates lower but the domestic crude oil production will unlikely increase in the foreseeable future above 200 kb/d. Still, the federation fares quite well as the OPEC pledged crude oil production cuts are concerned.</em></p> Eugene M.

Coral reefs serve multiple functions, both ecologically and economically. The marine waters in Wakatobi Regency boast diverse coral reefs, and this study aims to assess the coral reefs in one of its regions, specifically in the waters around Hoga Island, part of Wakatobi National Park. The research was conducted from March to May 2023, involving direct observations at the research site. The collected data were then analyzed and presented descriptively concerning the percentage of coral reefs in the study area. The percentage of coral cover in the growth forms (lifeform) of the Wakatobi National Park tourism zone, region II, revealed that, at the first station, coral cover was 46.33%, dominated by Coral Branching (CB) at 22.36%, and Biotic, primarily Soft Coral (SC), at 14.95%. At the second station, coral cover was 36.13%, with Coral Branching (CB) accounting for 11.53%, and Soft Coral (SC) at 25.33%. The third station exhibited a coral cover percentage of 60.37%.</em></p> Hawati Hawati, Mustafa Mustafa, Yusuf Yusuf, Angkasa Putra, Herianto Suriadin Copyright (c) 2024 Journal La Lifesci Fri, 02 Feb 2024 14:07:36 +0700 Optimization of PCR Analysis Based on Start Codon Targeted Markers (SCoT Markers) for Identification of Genetic Variation of Seaweed from Central Sulawesi <p><em>Seaweed is a fishery commodity that has high economic value because it contains carrageenan which can be used in the pharmaceutical, food, cosmetics, and industrial fields. Central Sulawesi Province is the second largest seaweed producer in Indonesia after South Sulawesi Province. The genetic diversity of seaweed in Central Sulawesi has not been studied much. Therefore, molecular-based characterization activities to identify the genetic variation of seaweed in the province are urgently needed. The purpose of the study was to optimize PCR techniques based on targeted start codon markers (SCoT markers) to identify the genetic diversity of seaweed accessions from Central Sulawesi Province. The results showed that the parameters for seaweed PCR amplification have been optimized. Of the fifteen SCoT primers, 10 of them can work to amplify seaweed DNA collected from several regions in Central Sulawesi. This is shown by the production of PCR result amplicons. PCR results also indicate polymorphism from the seaweed samples tested, although some seaweed samples have not been successfully amplified. The parameters of the PCR technique still need to be improved, especially the concentration of DNA prints, so that valid PCR results will be obtained for use in identifying seaweed genetic diversity.</em></p> Tri Joko Santoso, Ali Husni, Kristianto Nugroho, Zakirah Raihani Ya’la, Triyani Dewi, Marhawati Marhawati, Maemunah Maemunah, Eka Rosyida, Samliok Ndobe Copyright (c) 2024 Journal La Lifesci Mon, 12 Feb 2024 16:25:37 +0700
