Optimizing the Organization of Statistical Activities through the Revision of Law No. 16 of 1997 Concerning Statistics
Authors: Yuliarto Ramdhanul , Zeinudin Moh. , Warka Made
Published: November 2023

This research to find out and study how implementation of basic statistics carried out by the Central Statistics Agency based on Law Number 16 of 1997 concerning Statistics (Statistics Law); what are the obstacles in optimizing the implementation of basic statistics and how to overcome the obstacles in implementing basic statistics optimally through reform of the Statistics Law.  This research is normative legal research with a legal political and legal sociology approach, which examines the Statistics Law as positive law in the administration of basic statistics and formulates legal substance that should be implemented in the future.  The data source is secondary data consisting of primary legal materials and secondary legal materials. Data collection methods use library studies and interviews. Primary legal materials and secondary legal materials are analyzed using legal analysis methods. The deductive thinking process is used to draw conclusions. The theoretical basis used as an analytical tool in reviewing research results and discussions is the theory of legal effectiveness and public policy theory. The results of this research indicate that the implementation of basic statistical activities by BPS based on the Statistics Law is not running optimally because there are obstacles, such as: low public awareness of the importance and usefulness of statistics, the application of criminal sanctions for respondents that are not effective and statistical data in ministries/ Partial government institutions. These obstacles are fundamental and cannot be overcome casuistically but must be done with comprehensive and revolutionary efforts, so efforts to overcome them are by reforming the Statistics Law so that the implementation of basic statistical activities by BPS can run optimally. From this explanation it can be concluded that in order to obtain legal certainty for both BPS officers and respondents, an article is needed that guarantees legal certainty so that if respondents refuse, they can be given sanctions which of course must be regulated in the Law on Statistics. We as authors propose and suggest that the Government can immediately update the Statistics Law and correct the weaknesses we have mentioned above.

Authors: Nguyen Van Vui  , Nguyen Thi Kim Quyen  , Nguyễn Thuỳ Linh
Published: November 2023

Mineral ions have essential roles for maintaining osmotic balance, forming parts of primary
enzymes relating to the sperm metabolism and function. This study was conducted to
evaluate the effects of mineral salts as supplement to semen extender on chilled canine sperm
quality during 10 days of storage. The sperm motility was performed by computer assisted
sperm analysis (CASA). The plasma membrane integrity, acrosome membrane integrity, and
mitochondrial membrane potential parameters were determined using a fluorescent staining
combination. The results showed that although the percentage of sperm motility and sperm
plasma membrane integrity in the mineral salts and the control extenders were not markedly
different during the first 6 days of storage (P>0.05), the acrosome membrane integrity,
mitochondrial membrane potential and the healthy sperm parameters in the mineral salts
extender was substantially higher than that in the control extender during this period (P<0.05).
Notably, the sperm quality of sperm in the mineral salts extender decreased rapidly after the
first 6 days and evidently lower than that in the rest extender (P<0.05). In conclusion, the
mineral salts extender can improve sperm quality in chilled canine sperm during 6 days of
storage.

Authors: Ma. Leah M. Borines  , Candelario L. Calibo  , Ma. Theresa P. Loreto  , Edgardo E. Tulin
Published: November 2023

Cadmium (Cd), a toxic heavy metal is a common contaminant in rice paddy soil. Phytoremediation is seen as one of the cheaper methods of removing heavy metals from contaminated soil. This research was designed to test the efficacy of three weed species (Ipomoea aquatica L, Sphenoclea zeylanica Schmidt and Pistia stratiotes L.) associated with low-land rice (Oryza sativa L.) to extract Cd from a rice paddy soil near two industrial establishments in a rural area in the Philippines. Levels of initial and final Cadmium content of the soil were analyzed. Soil pH, and moisture, as well as the Cd content of the plants were also compared after harvest. The tested weed species significantly reduced the soil Cd level compared to rice and the negative control, suggesting the potential of these weeds in extracting Cd from the soil. Among the three weeds, Pistia stratiotes had the highest total cadmium concentration level followed by Ipomeoa aquatica, and Sphenoclea zeylanica, while rice had the lowest concentration. These weeds then can be used for the phytoremediation of Cd-contaminated soil.

Authors: Shiela Cres L. Nicolas  , Reynaldo G. Abad  , Marina Isabel A. Tac-an  , Emma Ruth V. Bayogan
Published: November 2023

Uniform flowering branches of 9 durian (cv. ‘Puyat’) trees aged 6 to 7 years old were tagged and then variously thinned (control, 25%, 50%) when the fruit were about 3 cm in diameter. The effect of fruit thinning on the yield and fruit quality was investigated. The fruit set, number of fruit harvested, total yield and percentage of misshapen fruit were not significantly affected by fruit thinning. Thinning to 50% tended to produce the least number of fruit set but produced the highest number of harvested fruit. Thinning at 25% and 50% both resulted in heavier fruit, greater pericarp weight, greater fruit circumference and longer fruit. The aril weight, seed weight and number of locules per fruit were similar in the 3 treatments. The 50% thinned trees produced fruit that dehisced a day later than the 2 other treatments, and these had the shortest length of fruit dehiscence, indicating slightly better shelf life under ambient conditions. In this study, fruit loss due to fruit drop was positively correlated(r=0.82; n=9) with rainfall during the period of study.
On the Effects of Albedo Increase through Reflective Roofing on Philippine Urban Atmospheric Temperature: Real-Time Parameter Inputs
Authors: Joey A. Caraquil  , Marie Khul C. Langub  , Rex M. Lucino
Published: November 2023

With global warming as one of the major concerns today, people try to find ways to control factors that affect atmospheric temperature. One of which is surface albedo. Akbari, et al. (2009), asserts that the use of modern reflective roofing and pavement materials can increase urban surface albedo by 0.1. This study utilized an agent-based simulation model in an experiment to verify whether this increase would bring about significant cooling of Philippine urban atmosphere. Real data obtained from reliable sources were used to set parameter values in the model. Simulation results showed that if the current levels of CO2 concentration and cloud cover would persist, such increase in albedo is not enough to significantly lower urban atmospheric temperature.

Authors: Hezekiah Oluwole Adeyemi  , Ogunlana Rufai
Published: November 2023

Manufacturing industries (Mrg-Inds) entails physically transformation of goods, with activities such as molding, cutting, and assembly, to final product. Hazards, associated with the activities in Mrg-Inds, are common among its workers. All the industries are face with tailored hazard risks and it is difficult to provide a common corrective measure. This study aimed at finding the possibility of integrating customized hazards in food, textile, chemical, leather and shoe, furniture and wood, and metal Mrg-Inds. The six industries assessed were located in Lagos and Ibadan, the southwestern part of Nigeria. Data were collected from 300 workers through questionnaire. Information related to peculiar types and prevalence of hazards in each of the industries were collected. Machine learning decision tree (Mld-tree) device, implemented in SPSS, was used to recognize the common hazards requiring the same decreasing measures. More than twenty-six hazards were collated from all the study areas. Chemical-related was rated (96.7%) major across the industries. This was followed by machinery-related (90%) and slips/falls (89%). The Mld tree spotted hazards related with ‘equipment’ and ‘ergonomics’ as the first chance node and the most common across all the industries. The chance node was ‘noise’ derived when hazards related with ‘equipment’ was further splatted into end node. The study identified hazards connected with ‘machinery’, ‘ergonomics’ and ‘noise’ as the integrated hazards prevalent in all the six Mrg-Inds that require common ergonomics intervention at reducing health and safety risks of workers in food, textile, chemical, leather and shoe, furniture and wood, and metal Mrg-Inds.

Authors: Salares Erik Francis O. , Balala Lotis M.
Published: November 2023

The challenge of antimicrobial resistance prompted exploration of therapeutic products from medicinal plants. This study evaluated the antimicrobial activity of T. catappa leaf extract against Staphylococcus aureus, Bacillus cereus, Bordetella bronchiseptica, Pasteurella multocida, Candida albicans, and Microsporum canis. Different concentrations were used to establish the minimum inhibitory concentration (MIC) and minimum bactericidal/fungicidal concentration (MBC/MFC) of the plant extract. The extract demonstrated a broad antimicrobial spectrum by inhibiting both gram-positive and gram-negative bacteria at MIC range of 5,000 to 10,000 µg/mL. C. albicans was inhibited at 78.12 µg/mL and M. canis at 312.5 µg/mL. The MIC-MBC ratios and the MIC-MFC ratios indicate that T. catappa leaf extract has bactericidal action, fungicidal action to M. canis, and fungistatic action to C. albicans. Tannins, saponins and alkaloids were detected from the extract, which may be responsible for the antimicrobial activities of the plant.

Functional Properties and Proximate Composition of Composite Flour from Banana (Musa acuminata x balbisiana var Cardaba C.) Sweetpotato (Ipomoea batatas Lam) and Glutinous Rice (Oryza sativa var glutinosa L.) Fermented with Lactobacillus plantarum (Orla-Jensen)-BIOTECH 1223
Authors: Omar D. Alo  , Lorina A. Galvez
Published: November 2023

Composite flour is advantageous in countries where wheat cultivation is not possible, like in the Philippines. Hence, locally available crops like bananas, sweetpotato, and glutinous rice were processed into flour as an alternative to wheat flour. The application of lactic acid bacteria fermentation will modify the quality of the native flour, which can further improve its range of applications in baking. Thus, the study was conducted to evaluate the quality of the Lactobacillus plantarum (Orla-Jensen)- BIOTECH 1223-fermented composite flour from banana, sweetpotato, and glutinous rice flour. Ten treatments were generated using Simplex Centroid Design with different levels of the three independent variables. Response Surface Regression Analysis on the functional properties ranged from, water absorption capacity (115.20-155.32%), oil absorption capacity (54.88-70.32%), bulk density (0.80-0.90%), swelling capacity (1.16-1.86 mL0, and gelation property (2-6%) of the fermented composite flour. Proximate composition ranged from, 9.66-12.00% (moisture content), 1.84-5.87% (crude protein), crude fat (0.12-2.48%), and ash (0.0019-0.0273%). Physico-chemical (total soluble solids and titratable acidity) and proximate composition (moisture content and ash content) of the fermented composite flour from banana (FBF), sweetpotato (FSPF), and glutinous rice flour (FGRF) were significantly influenced by the lactic acid fermentation using Lactobacillus plantarum (Orla-Jensen)- BIOTECH 1223. Therefore, the fermentation of composite flour from banana (FBF), sweetpotato (FSPF), and glutinous rice flour (FGRF) can improve the functional properties and proximate composition of the composite flour.

Published: November 2023

Riding in a taxicab is a common mode of public transportation. Due to its accessibility, it is very susceptible to robbery. The only security measure is the installation of the emergency light indicator at the top of the taxicab. This light indicator has problems on visibility and awareness. To address this problem, a tracking system which can send key information via Short Message Service (SMS) to the dedicated receiver is developed. Such information contains the driver’s location, car body and license numbers, and location coordinates with the utilization of the Global Positioning System (GPS). The system enables the user to track the coordinates and timing details using the Internet of Things (IoT) platform. The real time activities inside the taxicab can be retrieved using the camera through the Secure Digital (SD) card. During robbery, the nearby people can be alerted by triggering the toggle switch placed at the back of the steering wheel which then displays a blinking distress message —HELP at the top of the taxicab using a matrix display panel. To test the reliability of the system, the following experiments were conducted in three different locations within Cebu, Philippines: SMS delay test, reliability test of localized coordinates using Global Systems for Mobile (GSM), GPS repeatability test, camera capture test and data logging test. Experiment results verified that the designed system can effectively perform its desired functions. The integration of this system in taxicabs can alleviate and can help solve the robbery cases.

Authors: Marvin C. Credo  , Melvin G. Obus
Published: November 2023

CFLs are one of the most commonly used lighting fixtures in the modern era. Studies regarding its life cycle assessment (LCA) indicated that in the disposal stage CFLs have more hazardous potential to impact human health and ecosystem than the incandescent bulbs due to their higher metal-containing components. Thus, possible recycling of CFL bulbs with busted electronic ballast but still has its remaining life span should considered. By using experimental-developmental method, the study aimed to develop a prototype device to drive CFL bulbs with busted electronic ballast. The prototype was tested and evaluated regarding its efficiency as compared to original electronic ballast of CFLs. Results indicated that the developed prototype had efficiencies ranging from 75.6% to 90.8% respectively. Statistical tests also indicated that though found out to have numerical difference between the illuminations emitted by the lamp when driven by its original electronic ballast to the illumination it emits when driven by the prototype device, this numerical difference would not translate into a significant statistical difference.

Authors: Juvyneil E. Cartel  , Wilfren A. Clutario
Published: November 2023

The need for methodological advances in research as an important tool for instantaneous and better understanding on the dynamic and heterogeneous behavior in socio-environmental systems is increasing. In this paper, the greenhouse gas (GHG) emissions and mitigation rates, and their effect to human inhabitants of two mega cities namely, Metro Manila, Philippines and New York City, USA were studied. A simple framework to develop agent-based simulations using NETLOGO version 5.2.1 systematically was conducted. Factual data was introduced and then considered for the application for a dynamic model of GHG emissions and its effect to human population considering the mitigation programs implemented. The model came out to be reliable in projecting the livability of the two mega cities with a margin of error of approximately ±7%. Results showed that Metro Manila has higher livability compared to New York City by 6%. The results are quite alarming which suggest more involvement from the human inhabitants to GHG mitigation programs considering that the livability of the cities are mainly dictated by the population growth as observed. However, it has to be noted that the chance of involvement of the population should not go beyond the carrying capacity of an ecosystem.

This study designed, developed, and undertook performance evaluation of a mixed-mode solar dryer with solar tracking collector, which is integrated with electric heaters as a backup heat source for drying fermented cacao beans. The drying mechanism was based on the combination of direct radiation and convective heating with the incorporation of electric backup heaters to address the intermittent effect of drying. The solar tracking collector maximized thesolar reception during daytime by providing sufficient heat inside the chamber. The electric heaters also provided reliable heat sources during night time, preventing the occurrence of moisture re-absorption by the beans. The developed system maintained a drying temperature range of 40-600C by automatically switching the drying modes depending on the weather conditions. At the average drying rate of 0.17kg/h in 48 hours of continuous drying, it dehydrated the cacao beans from an initial moisture content in wet basis of 57.49% to 0.65%, against the ambient temperature of 200C-360C. Drying time was shortened by 50% against traditional open or natural sun-drying, which takes 4-6 days, reducing it to two days or 48 hours. The integrated design of the mixed mode solar dyer provided the ability to carry out the drying process continuously by optimizing heat sources while maintaining the drying requirements for cacao beans. This study validated that the solar dryer is suitable for drying cacao beans.
Gene Expression Analysis of Jasmonic Acid Related Genes during Root Infection of a Sugarbeet Cyst Nematode (Heterodera schachtii) on the Arabidopsis thaliana Plant
Authors: Mary Ann Jully B. Regis
Published: November 2023

In several plant species, the establishment of systemically acquired resistance is associated with enhanced transcription of a large number of genes. This study aimed to analyze the expression of Jasmonic Acid (JA) related genes (COI 1, JAR 1, PDF 1.2A) in roots and shoots during cyst nematode infection on the Arabidopsis thaliana roots. The gene expression analysis results showed that while PDF1.2A was down-regulated in the roots, the reverse occurred in the leaf samples 24 hours after the sugarbeet cyst nematode inoculation. This indicates that the shoot defense system was activated during nematode root infection, thus, there is a systemic acquired resistance occurring in the shoots.

Total Quality Management is often used as an indicator that determines the success or failure of a company within a certain period of time. The achievement of Total Quality Management at PT Sahabat Unggul International for the last seven years has not been maximized, and even tends to decrease. Factors that can affect total quality management include work discipline, commitment and individual characteristics. The purpose of this study was to determine the effect of work discipline, commitment, and individual characteristics on the total quality management of PT Sahabat Unggul International. PT Sahabat Superior International has high employee delays, 46% of employees go in and out per year, and the knowledge and skills of employees are not maximized, so the total quality management at PT Sahabat Superior International is still low.The type of research used is explanatory research, so this research is associative research which aims to determine the relationship between two or more variables (Sugiyono, 2018). The variables used in this study are work discipline, commitment and individual characteristics as independent variables and total quality management as the dependent variable. The population is 800 employees with a tolerance limit of 10% according to the sample calculation in this study totaling 200 employees of PT Sahabat Unggul International. This study uses the Non Probability Sampling method (not the entire population is taken).Work discipline, commitment, and individual characteristics together affect the total quality management of PT Sahabat Unggul International employees with a correlation coefficient value of 0.735 for work discipline, 0.760 for commitment and 0.741 for individual characteristics, which if interpreted, the trend is included in strong category. Work discipline, commitment, and individual characteristics also have a positive influence on total quality management as indicated by the regression coefficient value of work discipline 0.679, commitment of 0.701, and individual characteristics of 0.657 meaning that work discipline, commitment, and individual characteristics have a positive effect on total quality management.The t-test coefficient for work discipline is 4.166, commitment is 3.697 and the individual characteristic regression coefficient is 2.899. The influence of work discipline, commitment and individual characteristics together affects the total quality management at PT Sahabat Unggul International which is shown from the results of the determination test of 63% with a calculated F value of 113.33 which is greater than F table 2.65 and significance of 0.000 which is smaller than the 0.05 level of significance.

This study discusses job opportunities in six administrative districts/cities of DKI Jakarta Province which are influenced by several factors such as wage levels, quality of human resources, and regional economic growth. The purpose of this study is to analyze how the Provincial Minimum Wage (UMP), Human Development Index (IPM), and Gross Regional Domestic Product (GRDP) as independent variables affect the level of employment during the 2011-2021 period. This study uses secondary data obtained from the Central Bureau of Statistics (BPS). This data is then processed using panel data regression with the Common Effect Model (CEM) method.The results showed that partially the Provincial Minimum Wage (UMP) had a negative and insignificant effect on the level of employment opportunities, the Human Development Index (IPM) had a positive and significant effect on the level of employment opportunities, and GRDP had a negative and significant effect on the level of employment opportunities. However, simultaneously the three variables have a significant effect on the level of employment opportunities in regencies/cities in DKI Jakarta Province. The magnitude of the influence of the UMP, HDI, and GRDP in explaining the effect on the level of employment opportunity is 34.18%, while the remaining 65.82% is influenced by other factors outside the model.

Various types of structures can be constructed using reinforced concrete, including slabs, walls, beams, columns, foundations, frames, and more. The incorporation of structural steel and reinforcements in concrete enhances the strength and durability of structural elements while compensating for the tensile weaknesses in the concrete material. This study aimed to investigate the behavior of reinforced concrete beams utilizing structural steel of different shapes. Four types of concrete beams were prepared: a standard beam with normal reinforcement, and three composite beams, each featuring structural steel with different sectional shapes – T-section, I-section, and channel section. The consistent parameters included the cross-sectional area of the specimens, each measuring 100x150x450 mm, a steel reinforcement percentage of 2% of the total volume, and the compressive strength of the concrete. The conducted tests involved applying a concentrated load at the mid-span of each beam to examine the specimens’ behavior in terms of strength, flexural load capacity, deflection, crack patterns, and failure mode. The results of this study reveal that, given the same steel ratio, the load capacity of beams reinforced with structural steel of a channel shape has surpassed that of the other beams. Additionally, specimens with structural steel plates exhibited higher maximum deflections before failure compared to the beams with conventional reinforcement.
