Abstract

This study aims to determine the effect of the Project-Based Learning (PjBL) model on knowledge and attitude outcomes regarding the topic of etiquette in using social media. The type of research used is quantitative with a quasi-experimental design, specifically the non-equivalent control group design. The data collection techniques employed were tests and questionnaires. The research instruments consisted of a knowledge test and an attitude questionnaire.This study was conducted at SMK Mulya Husada Purwokerto, with the population being all 11th-grade students and the samples being students from Pharmacy class 1 and Pharmacy class 3. The data analysis technique used was non-parametric tests, namely the Mann-Whitney test.The results of the study showed that the PjBL model can improve both knowledge and attitudes, as indicated by Mann-Whitney test results, with an Asymp. Sig. (2-tailed) value of 0.000, which is less than 0.05. Therefore, the null hypothesis (H0) is rejected and the alternative hypothesis (Ha) is accepted. There is a significant effect of using the Project-Based Learning model in improving learning outcomes in Islamic Religious Education (PAI) subjects for 11th-grade students at SMK Mulya Husada Purwokerto

Abstract

This study aims to analyze the influence of internal and external factors on stock returns in destroying the food and beverage industry listed on the IDX from 2011 to 2021. The sample in this study used a purposive sampling technique or was based on specific criteria with 12 companies. This research data is panel data, namely a combination of times series and cross-section data, which is tested statistically using Stata. Three data analyses are used: model estimation test, model selection, and static panel regression model estimation results with the criterion of a P value < 0.05, so there is a significant influence between the independent and dependent variables. The research results prove that the best model chosen is the CEM model. The research results demonstrated that the variables ROE (P Value: 0.543 > 0.05), DER (P Value: 0.491 > 0.05), interest rates (P Value: 0.373 > 0.05), and inflation (P Value: 0.165 > 0.05) statistically does not affect stock returns. However, the exchange rate variable (P Value: 0.005 < 0.05) significantly impacts stock returns. The research results also prove that ROE, DER, interest rates, exchange rates, and inflation can explain stock returns of 12.30%. In comparison, the remaining 87.70% is influenced by other variables not included in the research.

Abstract

This study investigates the impact of venture capital assistance from LazisMu, entrepreneurial orientation, and digital transformation on the performance of Micro Small Enterprises (SMEs) in Karanganyar Regency. A quantitative approach was used by collecting data from 122 SME respondents who received assistance from LazisMu and have adopted digitalization in the marketing of their products. The data was analyzed using the Smart PLS method to test the relationship between variables. The results showed that business capital assistance from LazisMu has a significant effect on SME performance. However, entrepreneurial orientation has no significant effect. In contrast, digital transformation has a significant impact by improving the operational efficiency and business strategy of SMEs, helping them compete more effectively in a competitive market. This research provides important insights for LazisMu policies and similar institutions to support SMEs more effectively with follow-up research and qualitative approaches to understand more deeply the influence factors.

Abstract

Jati Utama Nusantara (JUN) is one type of growing regime of fast grown teak (Tectona grandis Linn. F) derivedfrom Jati Plus Perhutani (JPP). JUN trees have fewer branches and a more cylindrical-shaped trunk, as well asexhibit rapid growth compared to the teak cultivated from seed (conventional); accordingly, they can beharvested in a shorter time. Despite its fast growth, some studies showed that the wood had not met the SNI01-0608 standard as raw material for furniture. The research aimed to improve several physical and mechanicalproperties of young JUN wood through thermal compression treatment. The test sample for 5-year-old JUNwood was prepared with a size of 2.5 cm (thickness/radial) by 10 cm (width/tangential) by 30 cm(length/longitudinal), then compressed using a 25 kg/cm2-pressure for 40 minutes in three temperaturetreatments of 170°C, 180°C, and 190°C. Testing of wood mechanical and physical properties referred to ASTMD143. The wood crystallinity was observed using an X-Ray Diffractometer (XRD), and the wood surface wasobserved visually. Wood cell structure as supporting data was observed using a stereo-capable microscope(Zeiss). The results revealed that the thermal compression could improve the physical and mechanicalproperties of the densified JUN samples compared to the nonthermally compressed samples. Based on datasimulation, the wood samples' best physical and mechanical properties occurred at approximately 185°C's heatpress.

Abstract

Bark extracts of nine plant species from Lore Lindu National Park (NP) had been studied for the antioxidant potential and their cytotoxic effects. The antioxidant activity was tested by determining the peroxidevalue (POV) using the iodometric method. The toxicity test was done by counting the death of shrimp larva (Artemia salina) using Brine Schrimp Lethality Test (BSLT) method. The test results showed three bioactive components (saponin, flavonoid, and polyphenol) were mostly obtained fromthe 3 plant species that have low POV, namely Dysoxylum gaudichaudianum, Gardenia augusta, and Nauclea orientalis. The most striking of cytotoxic effects (LC50< 200 μg/ml) were found from Koordersiodendron pinnatum (170.86 μg/ml), Nauclea orientalis (182.89 μg/ml), and Kleinhovia hospita (191.35 μg/ml) extracts.

Abstract

Pengelolaan sampah yang baik merupakan salah satu upaya penting dalam menciptakan lingkungan sekolah yang bersih, sehat, dan berkelanjutan. Namun, masih banyak siswa yang belum memiliki pemahaman dan kepedulian terhadap pemilahan serta pengolahan sampah organik dan anorganik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan siswa dalam mengelola sampah melalui pelatihan pengolahan sampah organik dan anorganik di lingkungan sekolah. Metode yang digunakan meliputi sosialisasi, demonstrasi, praktik langsung pemilahan sampah, serta pembuatan kompos dari sampah organik. Hasil pelatihan menunjukkan adanya peningkatan pemahaman siswa mengenai jenis-jenis sampah, teknik pemilahan, dan manfaat pengolahan sampah bagi lingkungan. Selain itu, siswa menjadi lebih peduli dan berpartisipasi aktif dalam menjaga kebersihan sekolah. Kegiatan ini diharapkan dapat menjadi langkah awal dalam membentuk budaya peduli lingkungan dan mendukung terwujudnya sekolah yang bersih dan berwawasan ekologis.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif dengan media teka teki silang terhadap motivasi dan hasil belajar siswa pada mata pelajaran pendidikan agama islam. Pendekatan penelitian yang digunakan adalah kuantitatif dengan desain Quasi Experiment melalui rancangan Non-equivalent Control Group Design. Populasi dalam penelitian ini mencakup seluruh siswa kelas X yang berjumlah 348 siswa. Sampel ditentukan melalui teknik purposive sampling, yang terdiri atas kelas X-J sebagai kelompok eksperimen (30 siswa) dan kelas X-B sebagai kelompok kontrol (30 siswa). Teknik pengumpulan data dilakukan melalui instrumen angket untuk mengukur tingkat motivasi belajar serta instrumen tes pilihan ganda berupa pretest posttest untuk mengukur hasil belajar siswa. Data yang telah terkumpul kemudian diolah dan dianalisis menggunakan uji statistik Independent Sample T-Test. Diperoleh nilai signifikansi (Sig. 2-tailed) untuk variabel motivasi belajar sebesar 0,000, dan untuk variabel hasil belajar sebesar 0,000. Karena nilai signifikansi kedua variabel tersebut lebih kecil dari 0,05 (0,000 < 0,05), maka H0 ditolak dan Ha diterima. Dengan demikian, dapat disimpulkan bahwa penggunaan model pembelajaran kooperatif dengan media teka-teki silang berpengaruh secara signifikan terhadap motivasi dan hasil belajar siswa pada mata pelajaran pedidikan agama islam.
