Abstract

The livestock sector plays a significant role in providing quality feed to support the growth and productivity of poultry. Vegetables are widely used as an alternative feed, but the chopping process is still often done manually, which is time-consuming, labor-intensive, and produces uneven cuts. This study aims to design and build a vegetable chopper equipped with three types of blades and a chopping capacity of 1 kg per minute. The research method includes literature studies, conceptual design, manufacturing process, and testing of the chopped results. The machine consists of a 2.2 kW electric motor with 2850 RPM, an 8 cm long shaft, and three types of blades. The test results show that using three blades produces the most uniform chopped results, meeting the poultry feed standards (50–100 mm). This tool is expected to assist small and medium-scale farmers in preparing poultry feed more efficiently and hygienically.

Abstract

One of the main reasons people become disabled or die is because of a stroke. The key to swift and effective therapy is an early diagnosis. This research examines the relative performance of the Naïve Bayes and Random Forest algorithms in identifying stroke cases using data collected from patients at the Cipayung Health Center. Age, gender, BMI, smoking status, hypertension, and other physical and mental health issues are some of the characteristics represented in the 644 samples used in the study. Collecting data, cleaning it up, and then evaluating the model using metrics like recall, precision, and accuracy are all part of the research process. With a 92% accuracy rate, the Random Forest algorithm outperformed Naïve Bayes (87% accuracy rate), according to the data. Medical professionals may use these results as a guide to improve stroke detection, which in turn accelerates treatment and lessens the likelihood of consequences. The findings of this study also pave the way for future research into machine learning algorithms.

Abstract

The transformation of oil palm empty fruit bunch (EFB) incineration ash into granular potassium fertilizer offers a promising approach to recycling agro-industrial waste while producing value-added products. This study focuses on the formulation of EFB ash-based granules using tapioca starch as a natural binder, and examines the effects of binder weight and drying time on granule yield, pH, K₂O content, and moisture content. Tapioca starch was incorporated at five  different weight (5, 10, 15, 20,  and 25 g) to evaluate its influence on granulation performance. The results showed that increasing tapioca starch content significantly improved the granule yield, achieving a maximum of 67.91% at 15 g. However, there are no granular formed. The granular formed at weight of binder 25 g that resulted 67.22% yield and 36.72% Potasium. The pH of the granules slightly decreased with increasing binder dosage. Moisture content was influenced by both the binder weight and drying time; higher starch content retained more water. This study demonstrates that tapioca starch is a viable biodegradable binder for producing eco-friendly granular fertilizers from EFB ash, supporting sustainable waste valorization and agricultural practices.

Abstract

Nutmeg (Myristica fragrans) is one of Indonesia’s agricultural commodities with recognized health benefits as a traditional medicine. In addition, nutmeg has potential as a natural treatment for scabies. This study aimed to evaluate the effectiveness of nutmeg fruit bioactive compounds in scabies treatment. Nutmeg extraction was conducted using three different solvents: ethanol, ethyl acetate, and n-hexane. The extract with the most dominant phytochemical composition was further analyzed for bioactive compounds using GC-MS and antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Subsequently, the extract was tested against Sarcoptes scabiei mites obtained from 15 stray cats. The effectiveness of nutmeg extract was evaluated in a spray formulation by observing mite mortality and lesion reduction. The results demonstrated that the ethanol extract of nutmeg fruit contained the most abundant phytochemicals, with 3-Methyl-2,5-Furandione (21.26%) and Maleic Anhydride (14.21%) as the dominant compounds. The ethanol extract also exhibited strong antioxidant activity with an IC₅₀ value of 21.41 ppm. In vitro testing showed 100% mite mortality at a 25% extract concentration within 24 hours, while in vivo testing on scabies-infected cats treated with the nutmeg spray extract revealed a significant reduction in scab lesions compared to the control group. These findings indicate that nutmeg extract possesses potent acaricidal and antioxidant properties, making it a promising alternative treatment for scabies. Further studies are required to refine the formulation and explore its clinical applications.

Abstract

Permasalahan yang sering kali muncul pada aplikasi berbasis server side, adalah request request dan response dalam jumlah yang besar. Proses request serta response akan terus berlanjut selama pengguna berinteraksi dengan aplikasi, Jika hal ini terus berlanjut maka penggunaan sumber daya (resource) yang berlebih pada CPU dapat menjadikan perfoma aplikasi tidak optimal bahkan dapat menimbulkan crash, yang berdampak pada layanan dan kualitas aplikasi. Oleh karena itu, diperlukan teknik untuk menangani permasalahan tersebut. Metode yang diimplementasikan pada penelitian ini ialah membuat aplikasi berbasis server side dengan dua spesifikasi yaitu dengan module cluster dan tanpa module cluster, selanjutnya kedua aplikasi dengan spesifikasi yang berbeda, masing-masing akan dilakukan tahap pengujian performa serta monitoring, kemudian dilakukan proses analisa hasil perbandingan untuk mendapatkan kesimpulan. Module cluster akan membantu untuk melakukan teknik clustering, teknik clustering ialah mengelompokkan proses yang sama serta sering dieksekusi. Dengan teknik ini beban kerja pada CPU akan terdistribusi, sehingga memberikan peningkatan performa aplikasi.

Abstract

The application of the bankruptcy model using the Altman Z-score model is carried out to predict financial difficulties by using balance sheet analysis which can reflect the company's financial performance. Insurance companies are needed to minimize risks and uncertainties for futureprotection. Altman's Z-score model is analyzed through the calculation results if it is smaller than <1.1 it is concluded that the company is at high risk, if the calculation results are 1.1-2.6 it is concluded that the company is prone to bankruptcy, and if the calculation result is> 2.6 itcan be said that the company is healthy. So that the probability of bankruptcy can be estimated using the Z- score Altman method. This modeling can be used by insurance companies in making decisions. (MMG) Keywords: Bankruptcy, Financial Performance, Altman's Z-score Method

Abstract

Pengemudi ojek online merupakan kelompok pekerja sektor informal dengan tingkat mobilitas dan risiko kecelakaan lalu lintas yang tinggi. Asuransi kecelakaan diri berperan sebagai instrumen perlindungan finansial, namun pemanfaatannya sangat bergantung pada pemahaman tertanggung terhadap ketentuan polis. Penelitian ini bertujuan untuk menganalisis pemahaman pengemudi ojek online terhadap asuransi kecelakaan diri berdasarkan ketentuan jaminan, pengecualian, dan klausula penting dalam Polis Standar Asuransi Kecelakaan Diri Indonesia (PSKDI). Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan teknik pengumpulan data melalui kuesioner tertutup yang disusun berdasarkan ketentuan PSKDI. Informan penelitian berjumlah sepuluh orang pengemudi ojek online yang beraktivitas di wilayah Pamulang, Kota Tangerang Selatan. Analisis data dilakukan melalui tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa pemahaman pengemudi ojek online terhadap asuransi kecelakaan diri masih tergolong rendah dan bersifat parsial. Sebagian besar informan hanya memahami jaminan meninggal dunia akibat kecelakaan, sementara pemahaman terhadap jaminan cacat tetap, biaya perawatan medis, serta risiko yang dikecualikan dalam PSKDI masih terbatas. Temuan ini menunjukkan adanya kesenjangan antara ketentuan polis dan persepsi pengemudi ojek online terhadap cakupan perlindungan asuransi kecelakaan diri.
