Background: Stroke is a neurological dysfunction caused by impaired blood circulation to the brain. Stroke can cause disability for survivors, one of which is impaired physical mobility due to weakness in the extremities and decreased muscle strength that can hinder the fulfillment of daily life activities. Range of Motion (ROM) and rubber ball grasping are one of the non-pharmacological ways in providing nursing care to ischemic stroke patients according to evidence-based practice (EBP). Purpose: This study aims to explain the process of providing nursing care with Range of Motion (ROM) interventions and rubber ball grasping for the problem of impaired physical mobility in stroke patients in Mina 1 room of RSUDZA. Method: case study with one patient as the subject with impaired physical mobility. Results: what was obtained during 6 days of intervention was an increase in the patient's muscle strength before and after the intervention, which was initially 1, increased to 4. Conclusion: Physical mobility impairment was resolved because the patient's muscle strength increased much better. Suggestion: It is hoped that Dr. Zainoel Abidin Banda Aceh can continue to improve nursing care for stroke patients so that the care provided is more effective and can apply Range of Motion (ROM) and rubber ball grasping as non-pharmacological methods.

This research aims to analyze: (1) the general characteristics of farmers who convert rubber land to oil palm plantations in Sungai Gelam District, and (2) the economic impact of this land conversion, particularly on farmers’ income. This study uses a quantitative approach with survey data collected from rubber and oil palm farmers. The results show that there are notable differences in farmer characteristics, including capital, labor use, and market access. The average income difference between rubber and oil palm farmers is IDR 2,712,000, indicating higher earnings from oil palm cultivation. Based on the BNT test, with a value of IDR 405,000, the average income difference exceeds the threshold, confirming that the difference is statistically significant. Furthermore, the calculated F value is greater than the F table value, which strengthens the conclusion that there is a significant difference in income between rubber and oil palm farmers. Therefore, land conversion contributes positively to farmers’ income improvement.

Rubber (Hevea brasiliensis) is an important plantation commodity that contributes to improving rural livelihoods. However, the productivity of smallholder rubber plantations remains relatively low due to various technical constraints, socio-economic conditions, and limited farmers’ knowledge and technology. This study aims to analyze the influence of technical aspects of cultivation and socio-economic aspects on farmers’ knowledge and technology in rubber cultivation in Desa Antutan, Kecamatan Tanjung Palas, Kabupaten Bulungan. This research employed a mixed methods approach with a descriptive design. Quantitative data were collected through questionnaires distributed to 30 rubber farmers selected using purposive sampling, while qualitative data were obtained through in-depth interviews and documentation. Quantitative data were analyzed using multiple linear regression with SPSS software, while qualitative data were analyzed through data reduction, data display, and conclusion drawing The results indicate that technical aspects of cultivation and socio-economic aspects simultaneously influence farmers’ knowledge and technology in rubber cultivation. Partially, technical cultivation aspects have a more dominant effect than socio-economic aspects. Qualitative findings reveal that the main problems faced by farmers include improper tapping techniques, aging rubber trees, rubber price fluctuations, and limited access to agricultural training and extension services.

Non-hemorrhagic stroke occurs due to blockage of blood flow to the brain by a thrombus or embolus. The blockage results in focal neurological disorders that affect the musculoskeletal system, namely weakness in the extremities, which gives rise to nursing problems of impaired physical mobility. To overcome the problem of impaired physical mobility, rubber ball grip exercises (ball squeezing) are given. These exercises have been shown to increase muscle strength, prevent joint stiffness, and improve blood circulation. This scientific paper was conducted to determine the description of nursing care for non-hemorrhagic stroke patients with nursing problems of impaired physical mobility. During the meeting, the nurse provided rubber ball grip exercises (ball squeezing) for 10-15 minutes for 3 times in 24 hours. Evaluation of these actions showed that the patient who initially experienced weakness in the upper extremities with muscle strength 2-3 and after being given rubber ball grip exercises (ball squeezing), the problem of impaired physical mobility was resolved, as evidenced by the patient being able to perform therapy, the extremities feeling slightly lighter, and muscle strength 4. Therefore, it is recommended that non-hemorrhagic stroke patients be given rubber ball grip exercises (ball squeezing) to overcome impaired physical mobility.

Jambi Province is one of the largest natural rubber producing regions in Indonesia; however, rubber factories under GAPKINDO Jambi still face productivity issues, particularly the gap between production capacity and actual output, and productivity assessment that is still conducted manually by GAPKINDO Jambi. This study employs Decision Tree, Random Forest, KNN, and SVM algorithms within a structured pipeline involving preprocessing, feature selection, standardization, data balancing using SMOTE, and hyperparameter tuning. The proposed solution applies productivity level classification both individually and through paired combinations (ensemble voting). The results show that the Decision Tree + Random Forest model achieves the best performance with an accuracy of 0.84 and an F1-score of 0.83, confirming the effectiveness of ensemble methods in supporting productivity improvement decisions.

Rubber prices experience significant and prolonged fluctuations, which impact farmer incomes and management decisions. Understanding historical patterns and price predictions is considered crucial for production planning, marketing, and farmer protection policies. This study aims to identify the characteristics of rubber price time series in Lahat Regency and develop a reliable forecasting model to support short- to medium-term decision-making. This study uses secondary data on monthly average producer prices for the period January 2019–December 2023. The analysis includes the Augmented Dickey–Fuller stationarity test to determine the need for transformation, differencing, and/or logarithmic transformation when necessary, identification of autocorrelation patterns using ACF/PACF, model estimation on the processed data, and evaluation of residual diagnostics (Ljung–Box, normality test) and forecasting accuracy metrics (RMSE, MAE, MAPE, Theil). The level data shows non-stationarity and becomes stationary after the first differencing; The model on log-transformed data had significant parameters and higher explanatory power than the model on de-differenced data, with RMSE and MAPE values ​​within a reasonable range. Forecast confidence intervals widened at longer time horizons, indicating increased projection uncertainty. Conclusion: Validated forecasts can inform farmers and policymakers to manage price risk and design market interventions.

Rubber plants (Hevea brasiliensis) are one of the main commodities in the plantation industry which have high economic value. Rubber latex productivity is greatly influenced by the tapping technique applied. This research aims to examine various tapping techniques that are effective in increasing rubber latex yields and maintaining tree productivity in the long term. The method used includes comparative analysis of tapping techniques, such as angle and depth of incision, frequency of tapping, and use of latex stimulants. The research results show that tapping techniques with an angle of 30°–45° and an optimal depth that does not damage the cambium can significantly increase latex production. In addition, the use of ethefon-based stimulants has been shown to extend the latex flow period and increase yields without causing excessive physiological stress in plants. By implementing appropriate tapping techniques, rubber plantation productivity can increase sustainably without reducing the productive life of the plants.

Biomass is one of the materials that can be utilized as fuel. To ensure optimal quality, effective management of biomass is required to maximize its potential. One possible approach is the application of a biomass stove fueled by rubber wood pellets. By integrating a thermoelectric generator, data can be obtained to determine whether all aspects meet the established standards. This system is designed to generate electrical energy from combustion heat, supported by components such as a buck-boost converter and a 3V DC lamp. Testing was carried out using proximate and ultimate analyses on the fuel as well as the Water Boiling Test (WBT) on the stove, referring to SNI 8021:2020 and SNI 8021:2014 standards. The results showed that rubber wood pellets contained 7.64% moisture and had a calorific value of 4050 kcal/kg. The stove demonstrated an efficiency of 23.53%–37.28% and a fuel consumption rate of 0.61–0.77 kg/hour, both of which meet the requirements. In addition, the thermoelectric generator produced a voltage of 3.6 V and an electric current of 0.05 A, which are higher than those reported in previous studies (2.06 V and 0.01 A, respectively). Therefore, this thermoelectric biomass stove system is considered successful and feasible for further development as an alternative energy application.

Noise is a physical hazard in the work environment that caan reduce hearing loss, especially in the rubber processing industry. The research aims to describe the noise level and control efforts in the production area of PT. Karet XYZ Palembang City in 2025. This study uses a descriptive design with a cross-sectional approach.  Data were collected through direct noise level measurements using sound level meters at wet and dry production areas by taking 8 measurements and questionnaires on 75 selected purposive sampling workers.  Data analysis was carried out univariately. It shows that most of the measurement points have a noise level above the threshold value of 85 dBA in accordance with the Regulation of the Minister of Health of the Republic of Indonesia Number 70 of 2016. The highest values were recorded in the Hummer Mill engine (89,76 dBA) and the Cooling Tunnel (89,70 dBA). All respondents were exposed to noise for ≥8 hours/day. Noise control has been carried out with administrative techniques and the use of personal protective equipment (PPE) but has not been fully effective from the complaints of 7 workers regarding suboptimal protection. The noise level at PT. Karet XYZ and duration of exposure exceeding threshold values that increase the risk to workers health. It is necessary to increase the effectiveness of noise control with a technical, administrative approach and monitoring the optimal use of personal protective equipment (PPE).

This research aims to create batik tulis motifs with inspiration from three main plantation commodities in North Labuhanbatu Regency, North Sumatra, namely palm oil, rubber, and cocoa.

The problem of this research is that passing is still not right on target, has not mastered the upper passing technique correctly, lack of mastery and control of the ball, so the problem in volleyball extracurricular is the lack of volleyball upper passing ability. The research method used in this study is the experimental research method. The design in this study uses Two Group Pretest Posttest. This Two Group Pretest Posttest only has measurement result data, namely pretest and posttest measurements. the results of the t value in the experimental group using a plastic ball are -19.312> 1.7613 and in the experimental group using a rubber ball are -18.862> 1.7613. From the results of the T test table, the comparison of the results of training using plastic balls and rubber balls is to see the average value (Mean) on the pretest results using a plastic ball, the average value is 15.33, the posttest using a plastic ball obtained an average value of 27.13 with a difference in increase of 11.8. While the average value (Mean) on the pretest results of the exercise using a rubber ball, the average value was 15.27, the posttest using a rubber ball obtained an average value of 27.73 with a difference of 12.46. Thus, it can be concluded that training using a rubber ball is more effective in improving upper passing skills compared to training using a plastic ball.

Limitated of infrastructure is one of the issues affecting the continuity of education in Indonesia. The unequal distribution of facilities in schools undoubtedly makes the learning process less effective and impacts students' learning outcomes. This is particularly evident in physical education, sports, and health lessons, which require equipment for the learning process. The lack of equipment prevents the expansion of sports education and the introduction of other sports as part of the curriculum. One example is handball, which is rarely taught in schools due to the lack of balls. As a result, some schools resort to using other balls, such as volleyballs, to teach handball. Using a volleyball in handball lessons is ineffective, especially when it comes to shooting. This issue led the researcher to consider modifying the handball with a rubber ball, which is easy to find and resembles the size of a real handball. The researcher then implemented this modification in a two-cycle action research study. The results from the pre-cycle assessment showed that only 2 out of 35 students passed the shooting test. In terms of percentage, this means only about 6% of the students were able to shoot well. Following this, the researcher took action in the first cycle, and 19 students passed, about 54% of the sample. Since the results were still considered suboptimal, the researcher proceeded with the second cycle, where 32 students passed, around 91% of the sample.

Organisms and their natural environments are inherently connected and interdependent, with humans relying extensively on natural resources to meet daily needs and sustain life. Among them, indigenous communities maintain a distinctive relationship with their surroundings, guided by traditional ecological knowledge passed down orally from generation to generation. This body of knowledge, known as local wisdom, is deeply embedded within the natural, social, and cultural contexts of each community and plays a vital role in ensuring their long-term survival and well-being. The present study aims to examine the current socio-cultural conditions of customary law communities in three indigenous villages of Jayapura City—Kayu Batu, Kayo Pulau, and Skouw Yambe. Specifically, it seeks to identify the types of local wisdom practiced within these communities and to assess the efforts undertaken to preserve such traditions. A qualitative research approach was adopted, employing multiple data collection techniques, including direct observation, in-depth interviews with community leaders and members, and literature review of related studies and historical accounts. The findings indicate that, despite increasing pressures from modernization, urban expansion, and external cultural influences, these communities continue to implement local wisdom in managing and protecting their natural environment and resources. This includes sustainable harvesting practices, customary rules for resource allocation, seasonal restrictions to allow ecosystem regeneration, and culturally embedded conservation rituals. The endurance of these practices is supported by the functioning of customary institutions, strong kinship ties, community protocols, and collective decision-making mechanisms that integrate environmental considerations. In conclusion, the study demonstrates that the environmental stewardship, resource management practices, and cultural identity of these three customary communities remain actively upheld. This resilience underscores the critical importance of safeguarding indigenous knowledge systems as a foundation for environmental sustainability and cultural preservation in the face of contemporary socio-economic change.

. Dalam hukum Islam, wakaf berarti menyerahkan sesuatu hak milik yang tahan lama (zatnya) kepada seseorang atau nadzir baik berupa perorangan maupun lembaga, dengan ketentuan bahwa hasilnya digunakan sesuai dengan syari’at Islam. Harta yang telah diwakafkan keluar dari hak milik nazdir/ lembaga pengelola wakaf, tetapi mejadi hak milik Allah S.W.T yang harus dimanfaatkan untuk kesejahteraan masyarakat. Filsafat yang terkandung dari amalan wakaf yaitu menghendaki agar harta wakaf itu tidak boleh hanya dipendam tanpa hasil yang dapat dinikmati oleh mauquf alaih atau pihak yang berhak menerima hasil wakaf. Makin banyak harta hasil wakaf yang dapat dinikmati oleh yang berhak, makin besar pula pahala yang akan mengalir kepada wakif. Selanjutnya persoalan yang menyangkut siapa yang akan melakukan perawatan, pengurusan dan pengelolaan aset wakaf yang dalam istilah fikih dikenal dengan nadzir wakaf, atau mutawalli wakaf termasuk hal yang sangat krusial. Hal itu karena aset wakaf adalah amanah Allah S.W.T yang terletak di tangan nadzir. Oleh sebab itu, nadzir adalah orang yang paling bertanggungjawab terhadap harta wakaf yang dipegangnya, baik terhadap harta wakaf itu sendiri maupun terhadap hasil dan upaya-upaya pengembangannya. Institusionalisasi Nazhir wakaf dapat dilihat pada pengaturan nazhir menjadi nazhir badan hukum, nazhir organisasi dan nazhir perorangan yang akan dibina oleh Badan Wakaf Indonesia. Maka pengembangan harta wakaf di Indonesia didaftar dan diatur oleh suatu lembaga yang khusus menangani wakaf. Salah satu bentuk lembaga yang berkembang di Dewan Da’wah Islamiyah Indonesia adalah lembaga wakaf produktif. Lembaga ini sudah berdiri dari tahun 1967 dan baru dikembangkan pada tahun 2006. Pada mulanya bentuk wakaf yang berkembang di Dewan Da’wah Islamiyah Indonesia baru berupa wakaf tanah produktif. Tanah wakaf yang diproduktifkan mulanya seluas 20 Ha. Tanah wakaf tersebut kemudian dikelola dengan ditanami beberapa jenis tanaman seperti karet dan kepala sawit. Selain wakaf berupa tanah yang diproduktifkan, maka berkembang juga layanan wakaf qur’an. Hasil pengelolaan tanah wakaf digunakan untuk membiayai da’i-da’i yang dikirim oleh Dewan Da’wah Islamiyah Indonesia ke daerah-daerah dengan tujuan syi’ar Islam. Dana-dana yang terkumpul sebagai hasil dari pengelolaan tanah-tanah wakaf yang diproduktifkan sepenuhnya dialokasikan murni untuk kepentingan umat. Selain itu, hasil dari pengelolaan wakaf tersebut juga dialokasikan untuk  pengelola atau nadzir.
