Authors: Prasiska Emilda , Rizkiana Fitria , Apriani Herlina
Published: January 2025

Science learning cannot only be taught in the form of concepts or theories but there needs to be practical activities in the learning process so that learning objectives can be achieved completely and comprehensively. Good science laboratory management will support the success of science learning in schools. Seeing the importance of science laboratories as a support in teaching and learning activities to achieve the expected competencies for students, science laboratories in schools need to be managed properly so that the use of science laboratory tools and functions can be achieved effectively and efficiently. This research was conducted at SMP Negeri 1 Anjir Muara with a type of research using a qualitative descriptive approach, with data collection techniques, namely observation, interviews, and documentation. Data analysis techniques used data reduction, data presentation and drawing conclusions. Based on the results of the study, it is known that of the four functions of laboratory management, namely planning, organizing, implementation, and controlling in general, they run well even though of the four functions there are two laboratory management functions that are not optimal due to limited human resources available at the school. Limited skilled human resources are one of the main obstacles in optimizing laboratory functions. Therefore, there needs to be a training program and development of teacher competencies in laboratory management, operation of practical equipment, and management of consumables.

Dissemination and Development of Original Cajuput Oil
Authors: Octavina Avi Fibry , Handayani Sri
Published: January 2025

If we like to use Cajuput oil after bathing, for aromatherapy, for health, and freshness, can we guess where the plant comes from? It turns out that this Cajuput comes from Indonesia. The Cajuput plant belongs to the guava (Myrtaceae), genus Melaleuca. The native Indonesian Cajuput plant can produce oil through the processing process of leaf extracts and plant branches. The results of this preparation can be used for various needs, including: treating headaches, colds, toothaches, diluting chest mucus, and various other health benefits. Its distinctive aroma gives a unique impression of freshness. The use of Cajuput oil can also be combined with other products, such as antiseptic lotions to treat rheumatism. Apart from that, this oil can also be used without adding any other products. Although Cajuput has been widely used by the community, especially for health therapy, the use of this oil can still be improved. Now the plant has been developed by expanding the planting area as well as applying modern technology to obtain better quality.
Insecurity, Poverty and Development Challenges in Nigeria
Authors: Dr Uzoh Dr Uzoh , Nzekwe E. Nzekwe E.
Published: January 2025

Worldwide, insecurity poses a big challenge to developed and developing nations, ironically, in the twenty first
century; but developing nations has poverty to contend with in addition to insecurity. This paper examines
insecurity and poverty challenges and implications on economic growth of Nigeria. The study was designed as
ex-post factor research, using time series data sourced from official and government publications; spanning from
1999 to 2023 (4th Republic). The variables used for the study were sourced after adequate considerations of extant
literature and objectives of the study. (Government expenditure on defense, education, health and inflow of
foreign direct investment were the independent variables while Economic Growth is used as proxy for GDP -
dependent variable). Among the findings are that insecurity/poverty has the potential of social dislocation,
displacement of businesses, stagnation of business activities, and significant influence on Economic Growth and
Economic Development of Nigeria; and concluded that national insecurity/poverty eradication must be of high
consideration as business activities thrive in a secure environment, which ultimately ensures sustainable economic
growth and development. We therefore recommend effective measures to be taken by the federal government to
deescalate insecurity by first purging the armed forces of the so called repented Boko Haram members that were
absorbed into our military. There is no point playing the Ostrich; since there were proven cases of insider leakage
of planned military operations against Boko Haram. A synthesis of composite security management approach
model and two-way approach model in addressing the ills of insecurity in ensuring Nigeria economic
sustainability is equally recommended.

Published: January 2025

The overall aim of this study was to investigate the introduction of new technologies by ENABEL to improve the rice value chain in the Banalia area. At the end of this investigation, we analysed the different types of rice milling technologies, their yield, and the profit they generate for the beneficiaries.
The surveys were carried out in Tshopo Province, specifically in Banalia Territory, and the results of these studies show that:
The analysis of the results shows that :
- The UFF takeover achieved a higher profit of USD 1,658.4 in 2022, followed by the
AMANI takeover.
- In the case of UFF, for example, the active members of this association shared out 60% of the profits in 2022, i.e. an amount of USD 1,472,524.
It is clear that OPAs' profits, sales, gross and net margins have declined over time, resulting in a profit of:
- For the Amani takeover bid with a profit of $1,138.3 in 2022 compared to $0 the following year.
- For the BASULE Women takeover bid, with a profit of $843.72 in 2022 compared with $722.4 in 2023.
- OPA Pain pour la vie, here the profit was $663.9 in 2022 compared to $489.2 in 2023.
- OPA Pamoja tu Jenge , the profit was $ 141.7 in 2022 against $ 85 in 2023 ;
- OPA CUAM, earned $819.9 against $101.89
- UFF's takeover bid gave it a profit of $1,844.4 in 2022, compared with $1,472.5 in 2022.
- OPA ASCIDEAZ had realised $1,239.6 in 2022 against $1,607.9 in 2023
There are several possible explanations for these results, but what really caught our attention was the fact that, after the project ended, most of the local partners were unable to sustain the project's achievements.
Numerical Investigation of Reinforced Concrete Frame With Weak Joints: A Preliminary Investigation
Authors: Adi Kusworo Ridan , Adi Kristiawan Stefanus , Alfisa Saifullah Halwan
Published: January 2025

A preliminary numerical investigation of the seismic performance of reinforced concrete frame structures with weak joint is conducted in this study. The structural numerical model was cut from the original experimental model as a preliminary investigation. The numerical analysis results show that no significant damage occur at the first story joint (weak joint). Based on the past experiment conducted, structural failure due to weak joint is lower than the structural failure due to non-ductile column. However, the structural response in the numerical model (acceleration, drift ratio, shear, and axial column) still does not match the structural response in the experimental model. This is because the numerical model doesn’t have inertial mass wagon as in the experimental model.
IoT-Based Monitoring and Control of a Hybrid Renewable Energy System Utilizing Solar and Microhydro Sources
Authors: Sompie Sherwin R.U.A. , Sambul Alwin M. , Rumpesak Iltsar C. A.
Published: January 2025

The growing need for sustainable and reliable energy solutions has led to increased interest in hybrid renewable energy systems that combine solar photovoltaic (PV) and microhydro power generation. This paper presents the design and implementation of a prototype hybrid system integrated with IoTbased monitoring and control. The motivation behind this work is to explore the viability of hybrid renewable energy systems for reliable power generation, especially in regions with variable weather conditions. This study highlights the importance of integrating microhydro power, particularly during rainy conditions, to supplement the solar system's reduced output. The system uses current and voltage sensors to monitor the performance of the photovoltaic panels and battery, measuring parameters such as capacity and energy output. An ESP32 microcontroller is used to collect and transmit real-time data to the Thinger.io IoT platform, enabling remote monitoring and management of the system. The results demonstrate the significant impact of weather conditions on the system's performance. Under sunny conditions, a 12Ah battery is fully charged in approximately 5 hours with a peak power output of 22.55 watts. In contrast, cloudy and rainy conditions result in much lower charging efficiency, with rainy conditions contributing almost no charging. Load testing revealed that the system, when powering two 10-watt lamps, ran for 273 minutes, while adding a 30-watt water pump reduced the battery life to 39 minutes, consuming a total of 11.46Ah.

Published: January 2025

Automatic gender detection is crucial in behaviour analysis and security surveillance applications, demanding effective algorithms for accurate target identification. This research proposes a gender recognition model based on a Convolutional Neural Network (CNN) architecture, specifically leveraging ResNet- 18. The model incorporates residual techniques to enhance feature map quality, thereby improving prediction performance. It utilises the UTKFace dataset, containing face images annotated with gender labels, was used to train the model. Experimental results demonstrate that the developed model achieves a validation accuracy of 91% and a validation loss of 0.7232, indicating a strong capability in gender identification from facial images. While these results are promising, there remains potential for further refinement. This research contributes to the development of a more efficient and accurate gender detection system through the implementation of a lightweight and practical CNN architecture. The model's feasibility for real-time applications suggests it can effectively distinguish gender in various operational scenarios.

Published: January 2025

Introduction: Traditional medicine by the community has long been used for medicine and health maintenance and has been inherited from generation to generation. Indonesia is very rich in beneficial plants. This study aims to discover the types of plants and plant parts and how they are processed for kapehe pie.
Research Methodology: The method used in this study is descriptive and exploratory with a qualitative approach. Data was collected by asking questions with the help of interview guidelines. The informants of this research are tatamba craftsmen and the Dayak Tribe of Sampirang II Village. The number of respondents was 35, consisting of farmers and homemakers.
Result: There are five types of plants used for the treatment of kapehe pai (gout), namely bay leaf (syzgium polyanthum), lemongrass (Cymbopogon citratus), ginger (zingiber officinale), kersen (Muntingia calabura), and garlic (Allium sativum). The most widely used plant is bay leaf allergy (syzgium polyanthum). Leaves are the most frequently used plant organs, which is 57.14% of the total, followed by rhizomes (22.85%), stems (11.42%), and seeds (8.57%). The medicinal plants are processed in two ways, namely by boiling and grinding/pounding, with a percentage value of 91.42% for the boiling technique and 8.57% for the kneaded method. 91% of the therapeutic plants are sourced from the gardens around the house, and the remaining 9% come from market purchases
Conclusion: Traditional medicine passed down from generation to generation treats kapehe pai (gout). The most widely used part of the plant is the leaf (57.14%), followed by rhizomes, stems, and seeds. Most medicinal plants are obtained from the gardens around the house (91%), while the rest are purchased from the market. This shows the wealth of local knowledge and the utilization of natural resources in traditional medicine.

La historia de las Jefaturas de Operaciones Militares en México ha sidoprácticamente inexplorada. Este artículo ofrece un acercamiento a la creación yfuncionamiento de esta organización territorial militar entre 1917 y 1923, quecomprende los gobiernos de Venustiano Carranza y Álvaro Obregón, antes deldesarrollo de la rebelión delahuertista. La división militar reflejó las dificultadesde la pacificación del país y de la recentralización política. Esos procesos noconcluyeron con el ascenso del grupo Sonora al poder en 1920, por el contrario,su arribo propició el desarrollo de nuevos movimientos rebeldes, algunos localesy otros planeados por exiliados desde Estados Unidos. Los levantamientosobligaron al Ejecutivo federal a reorganizar, cual tablero de ajedrez, a los hombresque comandaban las jefaturas, quienes casi siempre se convirtieron en operadorespolíticos del centro, pero también en cómplices ocasionales de las sublevacionese incluso en líderes de las mismas.

The conditions for the existence and development of metallurgical enterprises and the ceramic industry today compel the search for technological solutions for the development of new types of refractory and ceramic materials, as well as materials science approaches for their design. Magnesia­carbon refractories meet contemporary operational demands for metallurgical units as lining materials due to their thermal stability, resistance to the destructive effects of molten metals, and constant or increasing strength with rising temperatures.
To enhance strength parameters, a design approach is employed to create a reinforcing phase within the matrix of magnesia­carbon material. This phase is synthesized at elevated temperatures by implementing conditions favorable for its formation and by modifying phenol­formaldehyde resin during raw material preparation.
The physic­mechanical properties of non­sintered magnesia­carbon refractories were investigated using various types of modifiers (nickel sulfate, ETS­40, citric acid, and ammonium oxalate) introduced into the phenol­formaldehyde resin.
The study demonstrated the feasibility of modifying PFR to improve the strength of non­sintered magnesia­carbon materials and confirmed the necessity of introducing hexamethylenetetramine to form the resite structure of PFR. The influence of PFR modifiers (nickel sulfate, ETS­40) on the formation of the PFR resite structure and the SiO2 framework structure was identified, and their combined introduction was recommended to enhance the cold crushing strength to 56.3 MPa in magnesia­carbon materials after heat treatment at 180—200 ºС. It was shown that to ensure high­strength characteristics, the amount of nickel sulfate introduced into the PFR should not exceed 0.1 wt. %.

During operation, refractory concretes are exposed to the complex effects of thermal shock, corrosion, mechanical shock and abrasion, and the resistance of these materials depends on such factors as chemical composition, microstructure and phase transformations that occur at high temperatures. Given this, the present study investigated the effect of the amount of alumina cement of the Gorkal­40 brand and the addition of refractory clay on the main properties of fireclay concrete before and after heat treatment. It was found that the introduction of an additive of 0.5 % clay into the concrete mixture containing 15 % Gorkal­40 cement provides samples with a set of high property indicators: apparent density 2.19 g/cm3; open porosity 20.3 %; cold crushing strength after 7 days of curing — 40.8 N/mm2, after firing at a temperature of 1350 ºС — 35.8 N/mm2.
The pilot product in the form of burner stone from a concrete mix of optimal composition was made. After firing, the burner stone had no external defects (it was not melted, had no cracks or notches, and had a uniform yellow color). Properties of the satellite samples: cold crushing strength after 7 days of hardening — 41 N/mm2, after firing at a temperature of 1350 ºС — 38 N/mm2; open porosity and apparent density of the fired samples — 20.2 % and 2.18 g/cm3, respectively.
Based on the research results, the technology of the fireclay concrete mix of the SSHBG brand, which is produced by the Institute according to technical specification TU U 23.2—00190503—445:2019, was improved.

The paper presents data on the ash microspheres compositions of domestic thermal power enterprises. The research results on the structural and phase features of the Kryvorizka TPP ash microspheres according to X­ray diffraction and electron microscopy data are provided. The physic­mechanical, thermophysical, and electrophysical properties of ash microspheres were determined. It is shown that zolospheres with a high iron oxide content (24—27 wt. %) are almost X­ray amorphous technogenic formations, but their heat treatment at temperature 850 °С allows to change of the phase composition in a directed manner. It was established that, as a result of such heat treatment, magimite, hematite, hercynite, as well as mullite and a small amount of magnesium spinel and quartz are formed in the zolospheres shells. The directed formation of various compounds in the phase composition of zolospheres allows to influence of such properties as thermal conductivity and TCLR, hardness, dielectric and magnetic characteristics, which determine the appropriate direction of their use.
The work also highlights our own positive experience of ash spheres used to obtain composite materials for various functional purposes. It is shown that the ash spheres of most domestic TPPs have a similar chemical composition, contain small closed pores inside the shells, and are characterized by low thermal conductivity and СTE. Therefore, it is better to use them as a filler for composite insulation, including heat­insulating paints for building structures and communications. Zolospheres that acquire a crystalline structure through heat treatment increase their abrasiveness due to the formation of phases with high hardness (hercynite, magnesium spinel). It is expedient to use such ash spheres as a secondary filler of diamond­abrasive composites for instrumental purposes. During grinding, they form additional cutting surfaces, which helps to increase the processing productivity of highly plastic alloys by 1.7—1.8 times while ensuring the necessary quality of diamond processing (Ra = 0.20—0.25 μm.) and reducing its cost by 1.5 times. On the other hand, ash spheres, in the shells of which ferromagnetic compounds (maghemite, hematite) are formed during heat treatment, have prospects for use as a filler for radio­absorbing composite materials and coatings.

The hydrothermal synthesis of oxide particles is a versatile approach for obtaining materials with various morphologies and specific properties, which makes it promising in many fields of science and technology. This work aims to investigate the effect of alloying additives, such as titanium dioxide and silica, on the surface morphology of particles, their crystallinity, as well as on the optical and surface properties of the synthesized materials. The objective of the study was to investigate how these additives affect the process of particle formation during hydrothermal synthesis and their subsequent functionality.
To achieve this goal, several methods were used, including X­ray diffraction to determine the crystallinity of the particles, scanning electron microscopy to analyze the surface morphology, and photoluminescence to assess the surface activity of the resulting materials. The thermodynamic calculation confirmed the effect of alloying additives on the formation of oxide particles and also allowed us to assess their influence on the stability of the obtained structures.
The results of the study showed that the introduction of titanium dioxide and silica significantly reduces the aggregation of particles, which allows to obtain more homogeneous materials with improved properties. In particular, the use of titanium dioxide significantly increased the surface activity and photoactivity of the resulting material. This was confirmed by analyzing light absorption in the ultraviolet and visible regions of the spectrum, where an increase in absorption intensity was observed, indicating the prospects of using this material in applications requiring high hydrophilicity and a developed specific surface area.
Thus, the obtained results confirm the effectiveness of the approach used to synthesize oxide particles with the desired properties. The used method of hydrothermal synthesis, supplemented with alloying additives, allows not only to control the morphology and crystallinity of the obtained particles but also to significantly improve their functional characteristics. This opens up new opportunities for creating materials with improved performance properties for various industries, including catalysis, sensors, and other technological processes requiring high surface activity.
