Currently, climate change poses a threat to agriculture, including in the Bengawan Solo watershed. This study aims to explore farmers' perceptions of climate change and understand the adaptations they undertake. The study was conducted in Mejuwet Village, Sumberrejo Subdistrict, Bojonegoro Regency, using qualitative. This study involved six informants, consisting of three farmers and three farm laborers. The selection of informants was based on the criterion of having more than ten years of experience in farming. Data was collected using in-depth interview and observation. Subsequently, the data were analyzed using an interactive model. The study indicates that farmers have knowledge of and can articulate the climate changes they have encountered, albeit with some limitations in understanding, and they actively participate in adaptation efforts. Farmer adaptation encompasses technical modifications like establishing planting schedules and methods, and choosing high-quality varieties. Cultural adaptation encompasses traditions like the wiwitan ceremony. Social adaptation involves using social connections and prioritizing investments in children's schooling. Lastly, economic adaptation involves broadening job opportunities and liquidating assets.

Broccoli is abundant in fiber, vitamins, and minerals and is useful as a complement to main dishes. However, the use of broccoli during baking is still limited. Therefore, an experiment was conducted to explore the use of broccoli as a substitute in the recipe of a traditional cake, Kue Lumpur, as a traditional Indonesian snack for various events. This study aimed to determine how to make green broccoli puree, the process of making Kue Lumpur with green broccoli puree substitution, the response of panelists, and the nutritional content of Kue Lumpur from green broccoli puree substitution. The experimental design research was conducted at Makassar State University from December 2021 to February 2022. The participants were 16 trained panelists.

Non-invasive potato defects detection has been demanded for sorting and grading purpose. Researches on the classification of the defects has been available, however, investigation on the severity level calculation is limited. For the detection of the common scab, it has been found that imaging in the infrared region provide an interesting characteristic that could distinguish defected area to normal area. Thus, investigations on this wavelength range is interesting to add more knowledge and for applications. In this research, the multispectral image has been obtained and investigated especially at three wavelengths (950, 1 150, 1 600 nm). Image pre-processing and pseudo-color conversion techniques were explored to enhance the contrast between defects, normal background skin area and soil deposits. Results show that external defects, such as common scab and some mechanical damage types, appear brighter in the near infrared region, especially at 1 600 nm against the normal skin background. It has been found that pseudo-color images conversion provides more information regarding type if surface characteristics compared to grayscale single imaging. Image segmentation using pseudo-color images after multiplication operation pre-processing could be used for common scab and mechanical damage detection excluding soil deposits with a Dice Sorensen coefficient of 0.64. In addition, image segmentation using single image at 1 600 nm shown relatively better results with Dice Sorensen coefficient of 0.72 with note that thick soil deposits will also be segmented. Defect severity level evaluation had an R2 correlation of 0.84 against standard measurements of severity.

This study investigates the medicinal properties of Rhodomyrtus tomentosa by extracting its bioactive compounds with n-hexane, ethyl acetate, and ethanol. Ethyl acetate extract had the highest total phenolic content, while hexane extract had the lowest. The ethanol extract had the highest total flavonoid content, with hexane extract having the lowest. Ethanol extract showed the highest antioxidant activity with an IC50 value of 28.61 ± 0.56 μg/mL. Gas Chromatography-Mass Spectrometry profiling identified major compounds like menthol and salicylic acid. Fraction 6, with rhodomyrtone content of 728 μg/mL, had the most dominant rhodomyrtone compound. Higher solvent polarity correlated with higher total phenolic content, total flavonoid content, and antioxidant activity, but lower saponin content. Based on its contents, further studies are needed to investigate its ability to reduce enteric methane, enhance immunity, and adapt to climate change, both in vitro and in vivo in ruminant livestock.

Background and Aim: Irradiated chitosan can be used as a matrix for slow-release urea (SRU) production. This study aimed to (1) determine the optimal formulation of irradiated chitosan matrix for controlling nitrogen release and (2) evaluate the characteristics of SRU in vitro fermentation based on irradiated chitosan as a feed supplement. Materials and Methods: In the first phase of the investigation, four chitosan-based SRU formulations with varying amounts of acrylamide (3 and 5 g) and gamma irradiation (5 and 10 kGy) were evaluated. Scanning electron microscopy, Fourier transform mid-infrared spectroscopy, and ammonia release characteristics were used to observe morphological, functional group, and ammonia release characteristics. In the second phase of research, the most effective SRU formulation was utilized as a supplement to ruminant rations based on rice straw, sorghum straw, and alfalfa. Gas production, rumen fermentation characteristics, and methane gas production were observed in vitro. Results: On the basis of surface image analysis, the four SRU formulas generate a similar appearance. Compared with untreated urea, the SRU3 formula reduced the percentage of ammonia emission by 12.85%–27.64% after 24 h of incubation (p = 0.05), as determined by the first phase study. SRU3 became the basis for the second testing phase. The addition of SRU3 did not affect the optimal gas production in vitro. SRU3 treatment produced less gas than Optigen® treatment (p = 0.05). With regard to rumen fermentation and digestibility, Optigen® yielded better results than SRU3 (p = 0.05). However, the treatment with SRU3 resulted in reduced methane production compared to that in the control (p = 0.05). Conclusion: Irradiated chitosan as an SRU matrix may control the release of ammonia in the rumen medium. The SRU3 formulation is the most effective. The addition of SRU to rice straw-based rations reduces methane production without affecting in vitro digestibility.

Food safety is essential for consumers. One of the compound that are prohibited from being used to preserve chicken meat is formalin. It demands a fast classification and sorting process for chicken meat, whether it is processed further or not. The main objective of this research is to develop a model that can predict the formalin content of chicken meat at room temperature using a portable NIR spectrometer. The NIRS method utilizes electromagnetic waves in infrared radiation with wavelengths ranging from 740-1070 nm. The method used to process the data is partial least square discriminative analysis (PLS-DA) to determine the presence of formalin in chicken meat. The results showed that the best pre-treatment was using the 1st derivative which had calibration results with an accuracy value of 92.86%, sensitivity 94.05%, specificity 91.67%, and FPR 8.33%. While the validation results obtained an accuracy value of 92.86%, sensitivity 92.86%, specificity 92.86%, and FPR 7.14%.

ABSTRACT: Citrus represents a valuable repository of antioxidant substances that possess the potential for the preservation of meat quality. This meta-analysis aimed to comprehensively assess the impact of citrus additives on the quality and safety of chicken meat. Adhering to the PRISMA protocol, we initially identified 103 relevant studies, from which 20 articles meeting specific criteria were selected for database construction. Through the amalgamation of diverse individual studies, this research provides a comprehensive overview of chicken meat quality and safety, with a specific focus on the influence of citrus-derived additives. Minimal alterations were observed in the nutritional quality of chicken meat concerning storage temperature and duration. The findings demonstrated a significant reduction in aerobic bacterial levels, with Citrus aurantiifolia exhibiting the highest efficacy (P < 0.01). Both extracted and nonextracted citrus components, applied through coating, curing, and marinating, effectively mitigated bacterial contamination. Notably, thiobarbituric acid reactive substances (TBARS) concentrations were significantly reduced, particularly with Citrus hystrix (P < 0.01). Total volatile base nitrogen (TVBN), an indicator of protein degradation, exhibited a decrease, with citrus extract displaying enhanced efficacy (P < 0.01). Chemical composition changes were marginal, except for a protein increase after storage (P < 0.01). Hedonic testing revealed varied preferences, indicating improvements in flavor, juiciness, and overall acceptability after storage (P < 0.01). The study underscores the effectiveness of citrus additives in preserving chicken meat quality, highlighting their antibacterial and antioxidant properties, despite some observed alterations in texture and chemical composition. Citrus additives have been proven successful in 1) mitigating adverse effects on chicken meat during storage, especially with Citrus hystrix exhibiting potent antimicrobial properties, and 2) enhancing the hedonic quality of chicken meat. This research strongly advocates for the application of citrus additives to uphold the quality and safety of chicken meat.

Purwoceng (Pimpinella pruatjan) is Indonesia’s native herbs that grow in the highlands but its existence is hard to find. The reason is that purwoceng is difficult to cultivate. A controlled factor in cultivation, such as hydroponic types and nutrient concentration, can be used as a solution to this problem. Hydroponic types and nutrient concentration treatments can affect the secondary metabolites and antioxidant activity of the purwoceng root extract produced. This study aimed to determine total phenolic and flavonoid content, as well as antioxidant activity in three different hydroponic systems (nonrecirculating drip, recirculating drip, and nutrient film technique (NFT)) and two nutrient concentrations (1.5‰ and 2.0‰). The combination of recirculating drip with low nutrient concentration was the best treatment to produce an extract with high phenolic and flavonoid content. Purwoceng root extracts from nonrecirculating with high nutrient concentrations produced high antioxidant activity. The characteristics of extracts from recirculating with low nutrient concentrations were similar to those from the nonrecirculating drip. In contrast, extracts from recirculating with high nutrient concentrations were closer to extracts from NFT, proven by principal component and heat map analysis. Antioxidant activity related to total phenolic content, also the presence of betaine and bergapten in purwoceng root extracts.

This study aimed to evaluate the aromatic characteristic of patchouli essential oil (Pogostemon cablin Benth.) by near‐infrared spectroscopy combined with chemometric treatments. The study used 84 oil samples collected from around Indonesia, namely in Konawe, Kolaka, Bogor, Garut, Aceh, Jambi, and Masamba. Several pretreatments were used to process the spectral data, together with the application of partial least squares. The spectrum wavelength applied was between 1000 and 2500 nm. The spectra data were separated to develop two models based on their physical and chemical properties (Bogor, Garut, Konawe, and Kolaka in the first model; Aceh, Jambi, and Masamba in the second one). Liquid chromatography‐mass spectrometry (LC‐MS) was used as a reference method. Patchouli alcohol was established as the main chemical compound of this aromatic oil. The best calibration for the first model was that with mean center normalization as a data pretreatment, while for the second model, it was the one using the second derivative. Both models had a correlation coefficient higher than 0.90 and a coefficient of variation lower than 2.98%. In conclusion, near‐infrared spectroscopy can be employed as an accurate tool to determine the characteristic of patchouli oil.

Independent Learning-Independent Campus Program (MBKM) is a policy of granting the right for students to be able to take study activities outside the study program as many as three semesters with the division of two semesters of study outside the college and one semester in different study programs in one college. As well as teaching and learning activities, universities must report Independent Learning-Independent Campus activities to DIKTI every semester through the Neo Feeder PDDIKTI application. The Neo Feeder PDDIKTI application has a feature to enter the activities the operator will carry out. The operator enters this data individually on the Neo Feeder PDDIKTI application. This is a significant problem because the data entry process will take quite a lot of time, even though PDDIKTI has provided web service access to universities to optimize the data reporting process using the Neo Feeder PDDIKTI application. Building an application that can be used for recording MBKM activities by utilizing web services provided by PDDIKTI is the primary purpose of this study. The development of an application certainly requires a method as a framework or guide in facilitating the manufacturing process. The extreme Programming (XP) method becomes essential for applications with variable or non-fixed needs. This method has four working elements: planning, designing, coding, testing and software increment. The output generated by this study is an application for recording MBKM activities that use web service restful API technology so that data entry can be done en masse and not one by one.

Purwoceng (Pimpinella pruatjan) is an Indonesian native plant but difficult to cultivate. Hydroponics can be used as a solution for purwoceng cultivation. Hydroponic types and nutrient concentrations can affect purwoceng’s productivity. This study aimed to determine total phenolic content (TPC) and total flavonoid content (TFC), changes in steroid, and antioxidant capacity due to two hydroponic types (nonrecirculating and recirculating drip) and three nutrient concentrations (1,000, 1,500, and 2,000 ppm). Purwoceng was determined for its moisture content, ash content, and dry weight, and extracted with ethyl acetate for gas chromatography-mass spectrometry analysis and with ethanol for TPC, TFC, and antioxidant capacity. The data were analyzed statistically and grouped using principal component analysis (PCA) and heat map analysis (HMA). Nonrecirculating drip with high nutrient concentration at the aerial part was the best treatment to produce high TPC, TFC, and antioxidant capacity. There were no significant changes in steroid content. PCA showed that purwoceng extracts could be grouped in to two groups, i.e. aerial and root groups. HMA showed that purwoceng extracts could be distinguished from the abundance of palmitic acid and stigmasterol. The antioxidant capacity of purwoceng was directly proportional to the TPC value and also related to the presence of phytol, stigmasterol, and palmitic acid.

The COVID-19 pandemic crisis has created an opportunity for SMEs to improve the quality of their products or services and develop various strategies for offering goods or services based on their business concerns. COVID-19 should not be an impediment to SMEs increasing sales because SMEs can promote their sustainability business. The impact of the COVID-19 pandemic on business sustainability among micro-SMEs in Indonesia and Malaysia is highlighted in this paper. In this case, SMEs Indonesia, as a support for national economic activity in Indonesia, have been severely impacted not only in terms of total production and trade value, but also in terms of the number of workers who have lost their jobs as a result of the pandemic. We use survey methods and structured interviews with the business owner. Because of their small size, Micro SMEs are relatively adaptable, allowing them to change their business models quickly. SMEs with a large number of employees, on the other hand, will find it difficult to maintain overhead costs and implement changes in their business direction. SME business models must be reassessed in light of the new normal, post-MCO. They must reassess market expectations and become more aware of shifting habits. SMEs must investigate new markets and customer segments, launch new products, redesign the size and number of packages that are appropriate and relevant for the new market, and ascertain consumer desires. During the COVID-19 outbreak, small and medium-sized businesses ensure that their operations survive, adapt, and continuously improve productivity. We observe some of the business owners to learn what they can do to reduce the impact of the pandemic on their operations, ensure business continuity, and deliver better results in times of crisis. Twenty-five business owners (SMEs) share their experiences in the aftermath of the COVID-19 pandemic. The most difficult challenge for businesses during the pandemic is how to survive persistently and creatively. This requires business owners to optimistically modify their business models, and some business owners radically modify their business models to survive. While geographically diverse and each serving a different consumer, the five businesses profiled below all reflect the realities that the small business community is facing during this trying time.

Cahaya merupakan faktor penting bagi pertumbuhan dan perkembangan tanaman. Elemen penting dari pencahayaan meliputi kualitas (spektrum cahaya) dan kuantitas (intensitas dan lama penyinaran/fotoperiode). Penelitian ini bertujuan untuk mengamati pertumbuhan dan efisiensi penggunaan energi pada selada yang dibudidayakan secara hidroponik dalam plant factory dengan beberapa perlakuan fotoperiode. Selada dibudidayakan secara hidroponik dengan sistem Deep Flow Technique (DFT) dengan beberapa perlakuan fotoperiode (terang/gelap) yaitu 24/0 jam, 18/6 jam, dan 12/12 jam. Untuk perlakuan 18/6 jam sendiri diberikan dalam beberapa siklus terang/gelap berbeda yaitu 18/6 jam (1 siklus), 9/3 jam (2 siklus), 6/2 (3 siklus), dan 3/1 jam (6 siklus). Hasil pengamatan meunjukkan bahwa perlakuan 24/0 jam menghasilkan pertumbuhan dan hasil panen yang paling baik di antara perlakuan lainnya pada semua parameter pertumbuhan yang diamati. Dari efisiensi penggunaan energi, perlakuan 18/6 jam (1 siklus) dan 6/2 jam (3 siklus) memberikan hasil lebih baik dibandingkan perlakuan 24/0 jam. Hasil yang diperoleh ini bisa menjadi alternatif strategi penerapan pencahayaan buatan untuk memperoleh kondisi yang optimum baik dari sisi pertumbuhan dan efisiensi penggunaan energi.

Aceh is an important region for the production of high-quality Gayo arabica coffee in Indonesia. In this area, several coffee cherry processing methods are well implemented including the honey process (HP), wine process (WP), and natural process (NP). The most significant difference between the three coffee cherry processing methods is the fermentation process: HP is a process of pulped coffee bean fermentation, WP is coffee cherry fermentation, and NP is no fermentation. It is well known that the WP green coffee beans are better in quality and are sold at higher prices compared with the HP and NP green coffee beans. In this present study, we evaluated the utilization of fluorescence information to discriminate Gayo arabica green coffee beans from different cherry processing methods using portable fluorescence spectroscopy and chemometrics analysis. A total of 300 samples were used (n = 100 for HP, WP, and NP, respectively). Each sample consisted of three selected non-defective green coffee beans. Fluorescence spectral data from 348.5 nm to 866.5 nm were obtained by exciting the intact green coffee beans using a portable spectrometer equipped with four 365 nm LED lamps. The result showed that the fermented green coffee beans (HP and WP) were closely mapped and mostly clustered on the left side of PC1, with negative scores. The non-fermented (NP) green coffee beans were clustered mostly on the right of PC1 with positive scores. The results of the classification using partial least squares–discriminant analysis (PLS-DA), linear discriminant analysis (LDA), and principal component analysis–linear discriminant analysis (PCA-LDA) are acceptable, with an accuracy of more than 80% reported. The highest accuracy of prediction of 96.67% was obtained by using the PCA-LDA model. Our recent results show the potential application of portable fluorescence spectroscopy using LED lamps to classify and authenticate the Gayo arabica green coffee beans according to their different cherry processing methods. This innovative method is more affordable and could be easy to implement (in terms of both affordability and practicability) in the coffee industry in Indonesia.

The presence of natural cavities in karst morphology may cause severe civil engineering and environmental management problems. Karst formations will limit the expansion of urbanization, especially infrastructure development in limestone areas. Geophysical methods, especially electrical resistivity tomography (ERT) techniques, are effective and efficient solutions to detect voids below the surface. This study aimed to develop a subsidence hazard map as basic information for infrastructure development. The identification was made by measuring electrical resistivity tomography on eight profiles in the infrastructure development plan. In addition, it was also supported by geological mapping, particularly the structural geology and types of rocks around the site. The research area consists of massive limestone, bedded limestone, and cavity limestone with generally north-south joints. The analysis of geological mapping data and electrical resistivity tomography measurements showed that the cavity limestone was identified with a north-south elongated pattern in line with the fracture pattern found on the surface at the research area. The surface lithology type, the geological structures density, and the subsurface lithology were used to develop a subsidence hazard map. This information is beneficial in determining the safe location of infrastructure development based on disaster risk mitigation.

Blood level 25(OH)D3 in obese people Background: Currently, obesity is a world problem, even the World Health Organization (WHO) declared obesity to be a global epidemic and contributes 5% of global deaths in 2015. Recently, many studies have reported an association between vitamin D levels and the incidence of obesity, although the exact mechanism raises many questions. Objective: This study is to examine the correlation between levels of 25(OH)D3 and body mass index (BMI). Methods: The design of this research is an analytic survey with a case control approach. The population of this study was all students of the Faculty of Medicine, Malahayati University, Bandar Lampung. The number of samples in this study were 60 samples with details of 30 case samples (obesity) and 30 control samples (no obesity). The sampling technique used was purposive sampling. The data used are primary data from direct measurement results. The data were analyzed using the correlation test. Results: The results showed that only one sample had normal 25(OH)D3 levels, while most (more than 98%) had low and very low levels of 25(OH)D3. The correlation test showed that there was a significant relationship between 25(OH)D3 levels with BMI (p=0.008; r= -0.0338), gender (p=0.001; r= -0.457), and total cholesterol levels (p=0.009); r= -0,391). Conclusions: There is a relationship between levels of 25(OH)D3 with BMI, the lower the 25(OH)3 blood level, the higher the risk of increasing BMI. Further research is still needed to ensure that giving vitamin D to obese populations can reduce body weight or BMI.

Yogyakarta residents are enthusiastic about joining farmer groups utilizing urban yards by executing the Lorong Sayur (vegetable alley) program. Members of the farmer groups realize the potential for expanding urban farming in confined spaces like narrow alleys and other such locations. This study aims to determine the level of motivation and the factors affecting the motivation of urban farmer group members in implementing the Lorong Sayur program in Yogyakarta. The research was purposively conducted in Yogyakarta, precisely in the Districts of Umbulharjo, Danurejan, and Kotagede. Fifty-five respondents were selected using multistage random sampling. Both primary and secondary data, obtained through interviews utilizing questionnaires, observation, and documentation, were employed. The data were analyzed using a Likert scale and Spearman’s rank correlation coefficient. Three needs from Clayton Alderfer’s ERG theory have been proven to predict motivation: the need for existence fell in the medium category, and both the needs for relatedness and growth belonged to the high category. Spearman’s rank correlation coefficient discovered that income, frequency of counseling attendance, the agricultural extension workers’ role, and the role of farmer group leaders were all significantly related to urban farmer group members’ motivation to implement the Lorong Sayur program.

A method of non-destructively moisture content measurement of coffee beans is using near infrared spectroscopy (NIRS) which in general can be applied to determine chemical content of various organic materials. However, the commercial NIR instrument can not measure many samples in a single time, consequently the faster measurement can not be realized. The purposes of this research was to study the performance of modified NIR instrument prototype for measuring the moisture content of Java Preanger coffee beans. Performance study of modified NIR instrument was carried out on 50 coffee bean samples for determination of sample moisture content. The reflectance spectra of samples were measured by modified NIRS instrument and then water content of samples was determined by oven method. The spectra data and water content were calibrated by multiple linier regression method to find the best calibration model. The result of this research show that number of wavelengths chosen to predict the moisture content of Java Preanger coffee bean accurately is 17 wavelengths. The correlation coefficient (R) moisture content based on NIRS instrument and oven method was 0.902, this suggest that the model is able to explain 90.2% the diversity of existing data. The value of standard error calibration (SEC) and standard error prediction (SEP) was almost zero meaning that the error of prediction is low. This study also reveal that the value of residual predictive deviation (RPD) is 2.32, which means the prediction model for determination of Java Preanger coffee beans moisture content is good enough.

Non Linear Frequency Modulation (NLFM) method can suppress the peak sidelobe level without additional windowing function. NLFM doesn’t require any weighting function because it has inbuilt one. NLFM has a variable frequency deviation function due to the relation between frequency and time of the signal which is not linear so that it is possible to suppress of peak sidelobe level. This paper studies the characteristic of various NLFM waveform, such as NLFM Tri Stage Piece Wise (TSPW), NLFM S, and NLFM Taylor. The study of Pulse Compression of NLFM waveform consists of three aspects. First, analysis of pulse compression performance. Second, analysis of background noise. Last, analysis of Doppler effects. The simulation is done using Matlab software. The lowest value Peak Sidelobe Level (PSL)of NLFM TSPW is about -20 dB while NLFM S and NLFM Taylor are about -32 dB and -39 dB. Additive White Gaussian Noise (AWGN) and Doppler Effect influenced the value of PSL for each NLFM waveform. NLFM Taylor has the best NLFM waveform when the Doppler Effect and AWGN cause the value of PSL become high. Comparison between NLFM Taylor and Linear Frequency Modulation(LFM) is done in radar surveillance applications to analyze the detectability performance where the condition of Radar Cross Section (RCS) for each target has different significant value. The three targets are commercial airplanes, helicopter and fighter. For detectability performance, NLFM Taylor can detect more clearly than LFM conventional.

Perkembangan teknologi otomotif sekarang ini semakin pesat yaitu dengan fasilitas accessories mobil yang semakin lengkap. Namun berbagai fasilitas yang terdapat dalam mobil tanpa disadari menyimpan ancaman bahaya bagi pengguna mobil salah satunya ketika system pada AC (Air Conditioner) terjadi kebocoran maka gas CO (karbon monoksida) akan memenuhi ruang mobil yang tertutup. Gas CO ini sangat berbahaya karena gas ini tidak berwarna, tidak berbau, dan tidak berasa sehingga sulit untuk dideteksi yang dapat menyebabkan orang yang ada didalam mobil menjadi mati lemas tanpa disadari karena menghirup gas CO yang bocor. Dengan fenomena tersebut dibutuhkan sebuah alat yang dapat mendeteksi dan mengontrol kebocoran gas CO untuk memberikan rasa aman kepada pengguna mobil. Alat ini menggunakan kendali logika fuzzy sebagai proses pengambilan keputusan sebagai hasil nilai dari inferensi kerja array sensor. Pengendali utama pada sistem menggunakan mikrokontroller ATmega32. Ketika array sensor yaitu TGS2442 dan TGS2600 mendeteksi kadar gas CO >29,0 ppm berarti dalam status bahaya sehingga buzzer akan aktif diikuti motor DC yang menggerakkan kaca mobil agar terbuka. Berdasarkan lima kali pengujian yang dilakukan didapatkanlah rata-rata selisih error output gas sebesar 0.29 ppm disaat kondisi aman dan 3.87 ppm disaat kondisi bahaya.

Structural performance evaluation of composite concrete slabs that were constructed using partially precast concreting system which utilized Hybrid Fiber-Reinforced Lightweight Aggregate Concrete (HyFRLWAC) as stay in-place formwork and self-compacting concrete (SCC) as topping layer was conducted in this research. This paper focused on determining the appropriate strength limit criteria of interface between two different concrete layers. The tensile strength was tested using pull-off test, while concrete cohesion was investigated based on modified bisurface shear test, and dual L-shaped shear test was used to determine the effect of normal force on the shear strength of concrete interface. Sample variants were designed based on the substrate surface conditions, compressive strength of the topping layer, and magnitude of perpendicular normal force acting on interface area. The substrate surfaces were prepared in as-placed and grooved conditions for tensile test, cohesion, and shear strength test. Test results indicate that tensile strength, cohesion, and shear strength of the concrete interface are affected by surface condition of the substrate, compressive strength of the topping layer, and the normal force acting perpendicularly on the concrete interface area. Proposed formulation for bond strength prediction between HyFRLWAC as substrate and SCC as topping layer is also presented in this paper.

Sound-based positioning systems are a potential alternative low-cost navigation system. Recently, we developed such an audible sound-based positioning system, based on a spread spectrum approach. It was shown to accurately localize a stationary object. Here, we extend this localization to a moving object by compensating for the Doppler shift associated with the object movement. Numerical simulations and experiments indicate that by compensating for the Doppler shift, the system can accurately determine the position of an object moving along a non-linear path. When the object moved in a circular path with an angular velocity of 0 to 1.3 rad/s, it could be localized to within 25 mm of the actual position. Experiments also showed the proposed system has a high noise tolerance of up to −25 dB signal-to-noise ratio (SNR) without compromising accuracy.

The interaction of charged particles and satellites can result in partial or total loss, leading to the satellite's inoperable. Charging on the satellite is the dominant cause of malfunctions and failures of satellite components. Damage mitigation can be done through a series of experiments in which materials and satellite components are bombarded with high- energy electrons. In this study, electrons are generated and accelerated using an electron beam machine (EBM). The test material and electronic components are placed beneath the EBM's beam window, where a 300 keV electron beam bombards them uniformly. The experimental results show that the electron beam can penetrate all the test materials used as shields within 20 s, and the absorbance levels range between 67% and 98%. The penetration depths span between 0.16 and 0.46 mm and agree with the Kanaya-Okayama calculation. The values of stopping power for most materials show the ineffectiveness of materials for shielding. However, increasing the thickness, such as in the MLI case, can reduce the level of electron radiation absorption. This experiment provides recommendations on the selection of materials used for equatorial satellite shielding, particularly the next Indonesian LEO equatorial satellite, both in terms of material and size.
