Pengaruh hormon alami dan lama perendaman benih cabai merah (Capsicum annum L.) kedaluwarsa terhadap perkecambahan, pertumbuhan, dan produksinya
Authors: Tata Noor Fitriya Mirta Liana , Anwar Syaiful , Kusmiyati Florentina 
Published: September 2022

Red chili (Capsicum annum L.) is a vegetable that has high economic value. However, red chili production has decreased because of seed deterioration, such as expired seeds. Seed invigoration attempts to maintain seed germination ability when it has deteriorated. Extracts of onion and banana weevil can be used for invigoration. The research aimed to know the effect of various natural hormones, soaking time, and interaction of the two treatments of expired red chili seeds on germination, growth, and production. The research used a factorial, completely randomized design (CRD), which consisted of the type of natural hormones for soaking expired red chili seeds, aquadest as a control, onion extract 25%, banana weevil extract 25%, and onion extract 25% + banana weevil 25%; and soaking time for expired red chili seeds, i.e., 4 hours, 8 hours and 12 hours. Based on the result, The effect of soaking expired red chili seeds on natural hormones significantly impacted maximum growth potential, germination, growth rate, and simultaneous growth. Meanwhile, there were no significant effects on the vigor index, plant height, number of leaves, flowering age, harvest age, number of fruits per plant, fresh weight per plant, and fruit length. In addition, the treatment for a soaking time of expired red chili seeds for up to 12 hours had no significant effect on all observation parameters.

Published: September 2022

The application of Lean thinking to energy management is the methodology based on the application of the Lean values and the principles of wastes elimination of Lean system. One is then challenging and questioning why a process is using the amount of energy that it does and why it is using energy during non-production hours. One strives to continuously improve and reduce the energy used by implementing improvement ideas. Todays, the pressure of competition in the energy sector is very high. A enterprise that wants to make a difference should continuously run optimization from the production lines. The objective of this study is to measure the impact of Lean tools on energy consumption and energy efficiency improvement. Through a case study, authors point out changes in production and energy efficiency before and after implementing improvement (Kaizen) projects. Besides, this paper illustrate the framework of Lean tools application into energy sector as a guideline for energy efficiency management in industrial enterprises

Published: September 2022

The purpose of this research is to find out the comparison of the cost of renting karaoke rooms used by NAV Karaoke Management with the cost of goods using the Activity Based Costing System that will be used in this research, so that the results of the comparison can be known using this method. This Activity Based Costing System is worthy and relevant to be used in finding out karaoke room rental prices or it is not quite fitting for the current situation.
Descriptive - qualitative technique is used in this study so that researchers can come directly to the related research object, that is NAV Karaoke Braga Citywalk branch, to acquire the data and information needed with a case study approach. The analysis that is used is a comparative analysis, meaning that the researcher has intention to compare the price set by NAV management with the cost calculated using the Activity Based Costing System method with a description of the discussion.
The results of this study found a quite significant difference between the cost of goods set by NAV itself and the cost of goods calculated based on calculations using the Activity Based Costing System method, the description of the discussion shows the difference in prices for each type of room available in the current three-month period.
MARINE GEOMAGNETIC ANOMALY BELT AND ITS RELATIONSHIP TO THE REMNANT ARCS IN THE NORTHWESTERN JAVA SEA, INDONESIA
Authors: Kusnida Dida , Arifin Lukman 
Published: September 2022

The continuous marine geomagneticsurvey within a timeintervalof1-secondsampling and a precision of 0.1 nT was conducted in the northwestern Java Sea to identify and interpret the general trend of total marine magnetic anomalies and the possibility related to thegeological resourcepotential. These magnetic data were then processed according to the formula corrected and applied to marine magnetic data. The total marine magnetic anomalies of the northwestern Java Sea indicate a well-defined lateral trend belt of anomaly contours. Anomalies are divided into four delineation zones: Zones I, II, III, and IV. A preliminary analysis of these anomalies led to the interpretation, reflecting the residual of a slightly east-west trending geological body underneath.Examination of magnetic anomalies suggests Zone I and IV characterize a basinalarea, Zone II depicts a granitic belt, and Zone III describes a Cretaceousmagmatic arc system in the east that extends from Middle Java across the Java SeathroughSouthern Kalimantan. These magnetic anomalies seem to coincide with the free air gravity anomalies data derived from TOPEX satellite data.
Biosintesis dan Karakterisasi Nanopartikel Seng Oksida (ZnO-NPs) Menggunakan Ekstrak Daun Kenitu (Chrysophyllum cainito L.)
Authors: Syamsul Arifin Fawaid , Nazriati  
Published: September 2022

Nanoparticles are materials that have superior properties compared to similar materials that are larger in size when used as raw materials. One of the nanoparticles that is trending and has many applications is zinc oxide nanoparticles (ZnO-NPs). This study aimed to synthesize ZnO-NPs using kenitu leaf extract (Chrysophyllum cainito L.) and determine the effect of extract composition and pH on the size of ZnO-NPs. Kenitu leaf extract can prevent agglomeration in the synthesis of nanoparticles because it contains secondary metabolites such as antioxidants and polyphenols. ZnO-NPs were synthesized using green method by reacting kenitu leaf extract with zinc sulfate. The success of the synthesis was indicated by the similarity of the peaks of the synthesized compounds to the standard peaks of ZnO in X-Ray Diffraction (XRD) analysis and supported by the presence of Zn-O vibrations in the 405-768 cm-1 region in Fourier Transform Infra-Red (FTIR) analysis. Analysis of UV-Vis spectra showed that ZnO-NPs were relatively stable at wavelength of 308-330 nm with an absorption peak at 317 nm and a bandgap energy of 3.25 eV. The results of FTIR characterization showed the presence of vibrations of the carbonyl and hydroxy groups in kenitu leaf extract. The results of the Scanning Electron Microscope (SEM) characterization showed that the ZnO-NPs synthesized using 10 mL kenitu leaf extract at pH 7 with 0.15 M zinc sulfate had predominantly spherical shape with a size of 14.10 nm. Based on experiment result addition of kenitu leaf extract may reduce the size of ZnO-NPs, while increase of mixture pH during formation reaction of ZnO-NPs may increase the size of ZnO-NPs.
