Abstract

Minuman susu segar termasuk salah satu minuman favorit yang banyak dikonsumsi masyarakat, dan termasuk salah satu jenis minuman yang tidak dapat bertahan lama pada suhu lingkungan, akibat banyak sekali zat yang memicu bakteri untuk tumbuh dan berkembang biak dengan mudah di dalam susu. Pada penelitian ini dibahas tentang sistem pembunuh bakteri pada susu dengan menggunakan kombinasi sistem refrigerasi, heater dan listrik tegangan tinggi.Pada tahap awal susu segar dengan jumlah 4 liter dipanaskan oleh heater hingga mencapai suhu pasteurisasi (60oC – 70oC ), kemudian diberi tegangan tinggi listrik ( 25 kv) dan terakhir suhunya dipertahankan pada 4oC dengan sistem refrigerasi. Setelah proses-proses tersebut didapatkan hasil bahwa untuk mencapai suhu pasteurisasi dibutuhkan 844.800 Joule dalam waktu 40 menit. Tegangan listrik tinggi yang dikeluarkan flyback selama 5 menit mampu membunuh sebagian bakteri di dalam susu dan untuk mencapai suhu 4oC pada sistem refrigerasi butuh waktu 120 menit. Dengan proses-proses tersebut sistem berhasil menurunkan kuantitas bakteri di dalam susu.

Abstract

This study aims to build a decision support system that can choose the chairman of the Youth Red Cross using the Additive Ratio Assessment (ARAS) method and to overcome the problems faced by the selection committee for the chairman of the Youth Red Cross at SMA Negeri 1 Lebakwangi Kuningan, West Java. The ARAS (Additive Ratio Assessment) method is a multi-criteria decision-making method based on ranking using the utility degree by comparing each alternative's overall index value to the optimal alternative's overall index value. The results of the research obtained are the existence of a decision support system for the election of the candidate for the chairman of the Youth Red Cross, assisting the election committee in assessing and selecting candidates for the PMR board according to the criteria. The design of a decision support system for selecting the chairman of the Youth Red Cross at SMA Negeri 1 Lebakwangi is implemented using a web-based programming language, for the predetermined assessment criteria and sub-criteria can be stored systemized, thus enabling relatively faster processing. By using this decision support system application that has been designed, the assessment and selection of candidates for the chairman of the Youth Red Cross become more accurate and more accessible because it uses computerized media so that the selection of candidates for chairman can be more neat and systematic.

Abstract

This study aims to analyze the impact of product knowledge and promotion on honey pumpkin buying decisions at PT Askara Farm Indonesia. The research method uses a quantitative descriptive method with a survey approach with a sample 75 people. Data was collected by filling out a questionnaire for product knowledge and promotion with buying decisions. Then the data colleted was analyzed using SPSS 16.0 for windows a significance level (α) of 0,05 with data analysis methods consisting of Validity Test, Reliability Test, Classical Asumption Test ( Normality Test, Heteroscedastisity Test, Multicolinearity Test), Multiple Linear Regression Analysis, Coefficient of Determination and Hypothesis Testing. From the results of the study, the tcount value of the product knowledge variable (X1) was 2,509 ttable, namely 1.66600 and promotion with the promotion variable (X2) with a tcount value of 1.706 ttable, namely 1.66600 with an R Square of 0.336. Thus, the independent variables, namely product knowledge and promotions, have a positive influence on the dependent variable in purchasing decisions of 33.6%. ABSTRAK Penelitian bertujuan untuk menganalisa dampak pengetahuan produk dan promosi terhadap keputusan pembelian labu madu di PT Askara Farm Indonesia. Metode penelitian menggunakan metode deskriptif kuantitatif dengan pendekatan survey dengan sampel sebanyak 75 orang. Pengumpulan data dilakukan dengan pengisian kuesioner untuk pengetahuan produk dan promosi dengan keputusan pembelian. Selanjutnya data yang terkumpul dianalisa dengan SPSS 16.0 for windows dengan tingkat kemaknaan (α) 0.05 dengan metode analisis data yang terdiri Uji Validitas, Uji Reliabilitas, Uji Asumsi Klasik (Uji Normalitas, Uji Heteroskedastisitas, Uji Multikolinearitas), Analisis Regresi Linear Berganda, Koefisien Determinasi dan Uji Hipotesis. Dari hasil penelitian diperoleh nilai thitung variabel pengetahuan produk (X1) sebesar 2,509 ≥ ttabel yaitu 1,66600 dan promosi dengan variabel promosi (X2) dengan nilai thitung sebesar 1,706 ≥ ttabel yaitu 1,66600 dengan R Square sebesar 0,336. Dengan demikian variabel bebas yaitu pengetahuan produk dan promosi mempunyai pengaruh yang positif terhadap variabel terikat keputusan pembelian sebesar 33,6%.

Abstract

Purpose: Artikel ini mengusulkan model konseptual untuk menilai dampak (net benefits) dan ketahanan siber (cyber resilience) dari sistem informasi/teknologi terapan yang digunakan pada layanan publik, industri, lingkungan, dan kualitas hidup. Methodology: Penelitian ini menggunakan pendekatan integrative literature review dan theory synthesis (Torraco, 2005; Snyder, 2019), dengan merangkum temuan riset e-government, kualitas layanan digital, public value, serta praktik teknologi terapan di Indonesia (misalnya evaluasi kepuasan pengguna website e-government dan penerapan teknologi pemantauan keamanan berbasis Raspberry Pi). Results: Hasil sintesis menghasilkan model IMPACT-IS yang memetakan (1) enablers (kualitas sistem, kualitas informasi, kualitas layanan, tata kelola data, ketahanan siber, dan kapabilitas organisasi), (2) mekanisme (penggunaan, kepuasan, kepercayaan, literasi digital, dan partisipasi), serta (3) outcomes berupa public value dan manfaat lintas-sektor. Artikel ini merumuskan delapan proposisi yang dapat diuji secara empiris dan seperangkat indikator operasional untuk evaluasi program. Limitations: Artikel bersifat konseptual sehingga belum menguji model pada konteks institusi tertentu; validasi kuantitatif/eksperimen lapangan diperlukan. Contribution: Model ini menyediakan kerangka evaluasi yang sistematis dan dapat digunakan sebagai blueprint penelitian terapan maupun panduan perbaikan layanan digital bagi instansi publik, pengelola layanan industri, dan pengembang teknologi yang berorientasi dampak.

Abstract

The development of information technology encourages business actors to shift from manual systems to more efficient computerized systems. Loddy’s Pet Shop Cirebon still uses manual (non-computerized) transaction recording, which is prone to human error, data loss, and delays in financial reporting. This research aims to design and implement a payment system based on the Quick Response Code Indonesian Standard (QRIS), integrated with the store’s cashier system, to facilitate transaction processing and financial recording. The research method used is descriptive, with data collection techniques including observation, interviews, and literature study, while the system development adopts the Rapid Application Development (RAD) method. The system is built using PHP and MySQL and integrated with the Midtrans payment service to generate dynamic QRIS codes. The implementation results show that the system can minimize recording errors, accelerate payment processes, generate financial reports automatically, and improve operational efficiency. With this system, Loddy’s Pet Shop can enhance service quality and gain a competitive advantage in the digital era.
