This study aimed to compare the meat quality of different beef cattle breeds using ultrasound imaging. A total of 28 cattle, aged 1-2.5 years, from three breeds were analyzed: Wagyu (n=7), Bali (n=10), and Wagyu×Bali cross-breeds (n=11). Meat quality traits, including longissimus dorsi thickness (LDT), backfat thickness (BFT), intramuscular fat (IMF), and marbling score (MS), were assessed using ultrasound imaging. The association between breed and meat quality was analyzed using a completely randomized design (CRD) followed by Tukey's test. Additionally, principal component analysis (PCA) was employed to identify clusters of meat quality potential among the different breeds. The results indicated that Wagyu×Bali cross-breeds exhibited the highest LDT (46.380±4.770 mm), though the difference was not statistically significant (P≥0.05) compared to either Bali or Wagyu cattle. However, significant differences (P≤0.05) were observed between Bali and Wagyu cattle. For BFT, MS, and IMF, Wagyu cattle outperformed both Bali cattle and Wagyu×Bali cross-breeds, with values of 5.490±0.806 mm, 6.010±0.998, and 49.05±8.140%, respectively. The PCA revealed two primary clusters: the first cluster, comprising Wagyu cattle, accounted for 75.6% of the diversity and was characterized by BFT, IMF, and MS as key variables. The second cluster included Bali cattle and Wagyu×Bali cross-breeds, representing 21.5% of the diversity, without any specific meat quality variable as a defining marker. Ultrasound imaging effectively estimated meat quality in Bali cattle and their cross-breeds, demonstrating its potential as a tool for meat quality assessment across different breeds.

The categorization of the Low-Income Community category is based on the poverty indicators in the Multidimensional Poverty Index, including the dimensions of health, education, and living standards. The Proxy Means Test (PMT) can estimate household income or consumption by taking into account household conditions that are readily observable and cannot be manipulated. This method offers the advantage of being capable of determining both the poverty level of a household and the household's characteristics based on asset ownership and socio-demographic conditions. This study aims to estimate per capita consumption using OLS, Robust, Quantile, LASSO, and Ensemble methods. The application of these methods is intended to address various issues, including the presence of outlier data, multicollinearity, and uncertainties. The results indicate that none of the four methods used achieved the highest accuracy based on the MSE, MAE, and sMAPE criteria. Consequently, employing an ensemble model becomes essential to accommodate the element of uncertainty present in these four models. The application of the ensemble method is not only as a comparison between the models, but also as a means to capture the uncertainty contained in each model

Indonesia is a tropical country with a hot climate. In tropical nations such as Indonesia, heat stress is a key reason for the reduced productivity of dairy cattle. Heat stress is a combination of internal and external stimuli that affects an animal, raises its body temperature, and causes it to react physiologically. Most Indonesian dairy cattle are Friesian Holstein (FH), imported from European nations with a temperate environment with low temperatures in the range of 5°C–25°C. Indonesia has a tropical climate with a high ambient temperature that can reach 34°C during the day and the local relative humidity varies between 70% and 90%. Temperature and humidity are two microenvironment factors that may impact the production and heat release in FH cattle. More than 98% of the entire dairy cattle population in Indonesia is found on Java Island. On Java Island, there are between 534.22 and 543.55 thousand heads of cattle, while the dairy cattle population outside Java Island is just 6.59 thousand heads of cattle. The milk output climbs by an average of 3.34% per year, or approximately 909.64 thousand tons and the average annual growth in whole milk consumption was 0.19 L/capita. Indonesian cow milk output has been unable to keep pace with the country’s increasing demand. This study aimed to review the strategies to mitigate heat stress in FH dairy cattle in Indonesia.

Background and Aim: Resistant starch (RS) is difficult to digest in the digestive tract. This study aimed to evaluate the effects of heat-moisture treatment (HMT) on RS in cassava and examined its impact on rumen fermentation. Materials and Methods: Cassava flour was used as a raw material and used in a randomized block design with four different cycles of HMT as the treatments and four different rumen incubations in vitro as blocks. Treatments included: HMT0: without HMT (control), HMT1: one HMT cycle, HMT2: two HMT cycles, and HMT3: three HMT cycles. Heat-moisture treatment processes were performed at 121°C for 15 min and then freezing at -20°C for 6 h. Analyzed HMT cassava starch characteristics included components, digestibility, and physicochemical properties. In in vitro rumen fermentation studies (48 h incubation) using HMT cassava, digestibility, gas production, methane, fermentation profiles, and microbial population assessments were performed. Results: Heat-moisture treatment significantly reduced (p < 0.05) starch, amylopectin, rapidly digestible starch (RDS), and slowly digestible starch levels. In contrast, amylose, reducing sugars, very RDS, RS, and protein digestion levels were significantly increased (p < 0.05). Additionally, a reduced crystallinity index and an increased amorphous index were observed in starch using Fourier-transform infrared analyses, while a change in crystalline type from type A to type B, along with a reduction in crystallinity degree, was observed in X-ray diffraction analyses. Heat-moisture treatment significantly (p < 0.05) reduced rumen dry matter (DM) degradation, gas production, methane (CH4 for 12 h), volatile fatty acid (VFA), and propionate levels. In addition, acetate, butyrate, and acetate/propionate ratios, as well as population of Streptococcus bovis and Bacteroides were significantly increased (p < 0.05). However, pH, ammonia, and organic matter digestibility were unaffected (p < 0.05) by HMT. Conclusion: Cassava HMT altered starch characteristics, significantly increased RS, which appeared to limit rumen digestion activity, decreased rumen DM degradation, gas production, VFAs, and CH4 production for 12 h, but increased S. bovis and Bacteroides levels.

Entering the digital era, the culture of human life is increasingly inseparable from the use of electromagnetic waves which are very useful in supporting human life, but in the other side, it also has negative impacts in the form of radiation that threatens human health. Only few people realize that ornamental plants have many benefits other than as a decoration inside or outside the room. Several types of ornamental plants have the ability to absorb electromagnetic radiation emitted by electronic equipment. In this simple physics research, measurements were made to compare the absorption of several types of ornamental plants to electromagnetic wave radiation, those are karet kebo, betel, succulent, ivy plant, and snake plant. The research results show that snake plant’s ability to absorb electromagnetic wave radiation is the greatest than others. Research conducted on ivy shows that the absorption of ornamental plants to electromagnetic wave radiation is influenced by the distance of the plant to the radiation source, where the closer the distance between the ornamental plants to the source of electromagnetic wave radiation is, the greater the absorption of radiation occurs, resulting in a decrease in the intensity of electromagnetic radiation also getting bigger. The trend of changes in the absorption of electromagnetic wave radiation shows a decrease in each increase in distance according to the exponential graph.

The MICE industry is considered one with high economic attractiveness for investors. Regulations and user requests for a new building are required to meet green building standards. The Green Building Council Indonesia issues Greenship's green building certification system. A minimum of 56 points is required for additional investment costs but will result in savings in operations to get a platinum rating. This paper aims to determine what factors are influential in optimising construction costs through the value engineering method to achieve a green building rating tool with life cycle costs using Structural Equation Modelling. The finding is that energy is the most influential factor in obtaining platinum rating certification, which requires value engineering and lifecycle cost analysis to achieve optimal investment costs with additional costs from 7,494% to 4,689%. The novelty of this research is that the selection of materials/machines and working methods of the green concept that saves energy needs to be carried out from the beginning of the design to achieve a feasible payback period for new investments, which will be the commitment of the owner to build a green MICE.

Starting in May 2021, green building is mandatory for new buildings in Indonesia. Greenship is a green building certification system in Indonesia issued by the Green Building Council Indonesia (GBCI) which is a member of the World GBC for the conservation and efficiency of resources (energy, water, land, materials, and nature). Greenship will be implemented in MICE which is a building for Meetings, Incentives, Conventions, and Exhibitions that has a strong economic attractiveness in Indonesia, which has a population of 270 million. Using the SEM-PLS it was quickly concluded that energy is the most influential factor in achieving platinum ratings from GBCI.With the value engineering (VE) method and life cycle cost analysis (LCC), it is needed an additional 4,689% cost for the platinum grade green costs through energy optimization will get a payback period of 3 years and 10 months. The novelty of this research, since the design, it is necessary to take steps to measure energy efficiency and other resources with a selection of materials/machines and working methods of the green concept to know the amount of additional initial costs that do not much burden investment costs compared with some future benefits of green MICE.

Heat shock proteins (HSPs) associated with stress reactions play an important role in cell survival by activating numerous regulatory proteins and inducing black apoptosis. This study aimed to identify the potential SNPs of HSP70 gene in Kacang goats in Indonesia. Forty-three Kacang goats were selected from Sidoarjo and Tulungagung districts. The DNA isolated from blood samples was successfully amplified using the polymerase chain reaction (PCR) method with a pair of primers. The PCR products were sequenced in the coding region. The sequences were successfully aligned to determine the potential SNPs. A novel SNP (c.1311C>T) was found in this study. This SNP was categorized as a synonymous mutation. The insertion-deletion (in-del) mutation was also observed at the 1151st and 1161st nucleotide positions. Based on these mutations, four haplotypes were constructed where haplotype 1 had the highest frequency in Sidoarjo. Indonesian goats had no close relation with Iraqi goats according to Neighbor-Joing with Kimura’s 2-parameter approach. Haplotypes 1 and 2 in Indonesian goats had three different bases with all haplotypes in Iraqi goats in Median Joining Network. The study concluded that a novel SNP of HSP70 gene was identified in Kacang goats.

Non-formal schooling was affected during the Covid-19 pandemic. The goal of this study was to look at how digital technology may be used in the Non-Formal Education Program. We looked at how digital technology is transforming traditional labor structures and transitioning them to online models using a literature study. According to the data, digital technology has an influence on home learning (LFH). Because of the advent of digital technology, students are utilizing online programs to replace face-to-face educational paradigms. Both the non-formal and formal education models have benefits, such as instructors' digital competency in building online course programs, knowledge of parents' digital modes, and the potential of students' networks to study with digital devices. The right technique for all schooling must be devised. However, it has various flaws, including low motivation and poor skill development if not used in conjunction with the appropriate approach. As a result, for the online learning process to be successful, especially in non-formal education, the correct method must be developed.

Asymmetric body traits in bilateral organisms are common and serve a range of different functions. In crustaceans, specifically among brachyuran crabs, heterochely and handedness in some species are known to aid in behavioural responses such as food acquisition, and sexual and territorial displays. However, the heterochely of the intertidal mud crab genus Scylla is still poorly understood. This study investigated the cheliped morphometric characteristics of orange mud crab Scylla olivacea and the relation of heterochely and handedness to sex. Scylla olivacea is heterochelous, with predominant right-handed (70.2%). Three morphometric variables, i.e., propodus length (PL), propodus depth (PD), and propodus width (PW) were significantly larger in the right cheliped and the estimated handedness based on these three variables were consistent with the presence of molariform teeth. The effect of sex had no influence on the occurrence of heterochely or handedness. The frequency of left-handedness increased with size, especially in males. We postulate that handedness reversal, a phenomenon seen in other crab species when the dominant hand is lost, also occurs in S. olivacea, thereby resulting in a change in left-handedness frequency. The use of chelipeds by males in mate and territorial defenses might provide an explanation for the higher risk of losing a dominant cheliped and thus, higher left-handedness frequency compared to females. Future behavioural research could shed light on the selective forces that affect the handedness distribution in mud crabs. Knowledge on heterochely and handedness of mud crabs could be useful for future development of less aggressive crab populations by claw reversal and the optimisation of limb autotomy techniques.

The age of a woman when giving birth to her first child needs to be a concern because it is related to the safety of the mother and baby. A woman being too young or too old increases the risk of death for both the mother and baby. Every woman giving birth for the first time is likely to experience psychological disorders such as anxiety and excessive fear during labor, and even postpartum depression. Given the importance and possible extent of the consequences of women giving birth for the first time, this study intended to assess the factors that influence the age at first birth, especially amongst women of childbearing age in East Java. These factors include the age at first marriage, education, and region. The method used was the extended Cox regression model. The analysis shows that the age at first marriage and education are factors that significantly influence the age at first birth. The more mature the age at first marriage, the more mature the age at first birth. Likewise, the higher the educational status, the higher the potential for giving birth to a first child over the age of 23, especially amongst women who graduated high school and university.

The normal distribution approach is often used in regression analysis at the Response Surface Methodology (RSM) modeling stage. Several studies have shown that the normal distribution approach has drawbacks compared to the more robust t-distribution approach. The t-distribution approach is found to control size much more successfully in small samples compared to existing methods in the presence of moderately heavy tails. In many RSM applications, there is more than one response (multiresponse), which is usually correlated with each other (multivariate). On the other hand, the actual response surface habitually indicates the curve by the optimal value, so the second-order model is used. This paper aims to develop the second-order multiresponse surface model using a multivariate t-distribution approach. This work also provides the parameter estimation procedure and hypothesis testing for the significance of the parameter. First, the parameter estimation is performed using the Maximum Likelihood Estimation (MLE), followed by the Expectation–Maximization algorithm as an iterative method to find (local) maximum likelihood. Next, the Likelihood Ratio Test (LRT) method is used to test the parameters simultaneously. The model obtained uses this approach to determine the conditions of input variables that optimize the Paracetamol tablets’ physical quality characteristics.

Generating an accurate rainfall prediction is a challenging work due to the complexity of the climate system. Numerous efforts have been conducted to generate reliable prediction such as through ensemble forecasts, the North Multi-Model Ensemble (NMME). The performance of NMME globally has been investigated in many studies. However, its performance in a specific location has not been much validated. This paper investigates the performance of NMME to forecast rainfall in Surabaya, Indonesia. Our study showed that the rainfall prediction from NMME tends to be underdispersive, which thus requires a bias correction. We proposed a new bias correction method based on gamma regression to model the asymmetric pattern of rainfall distribution and further compared the results with the average ratio method and linear regression. This study showed that the NMME performance can be improved significantly after bias correction using the gamma regression method. This can be seen from the smaller RMSE and MAE values, as well as higher R2 values compared with the results from linear regression and average ratio methods. Gamma regression improved the R2 value by about 30% higher than raw data, and it is about 20% higher than the linear regression approach. This research showed that NMME can be used to improve the accuracy of rainfall forecast in Surabaya.

Traffic accident is one of the causes of death in the world. One of them is traffic accidents on motorcyclist not wearing helmets. To overcome this problem, several researchers have developed detection system of motorcyclist not wear helmet. This system consists of motorcycle detection and motorcyclist head detection. On motorcycle detection, accuracy still needs to be improved. For this reason, this paper proposed motorcycle detection by adding image improvement processes that are enhancing contrast and adding object positioning features.The techniques proposed in this study are divided into 3 stages of image enhancement, feature extraction, and classification. The image enhancement stage consists of enhance contrast, convert RGB image to gray scale, background subtraction, convert gray scale image to binary, closing operation, and small object removal. The features used in this paper are the features of the object area, the circumference of the object, and the location of the object, while the method for classification process using back-propagation neural network and SVM. The proposed method resulted in an accuracy of 96.97%. Error occurs in all image test data not motorcycle objects detected as motorcycle objects. This error is caused because the pixel value between the objects in the image with the background color has a level of difference is too small, so it is detected as an object not a motorcycle.

Lecturers have broad autonomy in developing instructional. With the characteristics possessed by these lecturers, collaboration between lecturers (team teaching) is a challenge that is sometimes not easy. However, in vocational learning, lecturer cooperation in learning is something that cannot be avoided. In the Classroom Action Research to SMK, researchers collaborated at partner schools of SMKN 5 Surakarta and SMKN I Mondokan Sragen. The type of research used is ethnographic research, which is a qualitative observation method used in social science that focuses on field studies and their interactions, and sees everything as unique. The method used in conducting the evaluation is the equivalent test, which is a test that aims to measure its reliability identically with the reference test. The conclusion that can be drawn in this PDS program is to complement each other's strengths and weaknesses in organizing the learning process for SMK. Pamong teachers who work together are senior teachers who have eaten a lot of salt in their teaching. Pamong teachers have adequate competence in teaching and educating students, on the other hand, senior teachers have limitations in developing learning innovations. This is where the role of PDS lecturers in completing the shortage of teachers. The innovation that the lecturers did was to provide guidance using e-learning in learning at SMK. This e-learning has many advantages in learning the millennial generation. By maintaining student motivation, the learning objectives will be better achieved.
