Judul: Implementasi Manual Sistem Jaminan Halal dan Sistem Hygiene Sanitasi di Warung Sego Bandarlampung
Abstrak: Warung Sego menyajikan menu makanan tradisional yang belum pernah diuji pemenuhannya terhadap persyaratan hygiene sanitasi dan persyaratan sertifikasi halal HAS 23000 sehingga keamanan dan kehalalannya belum terjamin. Penelitian ini bertujuan untuk menerapkan dan memaksimalkan semua kriteria manual Sistem Jaminan Halal (SJH) dan uji coba penerapannya di Warung Sego. Manual ini diperlukan sebagai panduan teknis untuk memenuhi persyaratan hygiene sanitasi dan kehalalan dari produk yang dihasilkan. Manual SJH disusun berdasarkan kondisi nyata rumah makan Warung Sego dan berisi tentang kriteria-kriteria implementasi sistem jaminan halal. Kriteria Sistem Jaminan Halal terdiri dari kebijakan halal, tim manajemen halal, pelatihan, bahan, produk, fasilitasi produksi, prosedur tertulis aktivitas kritis, kemampuan telusur, penanganan produk yang tidak memenuhi kriteria, audit internal, serta pengkajian ulang manajemen. Hasil penelitian menunjukkan bahwa pada saat pengimplementasian Manual Sistem Jaminan Halal terdapat beberapa kriteria yang belum terpenuhi yakni fasilitas produksi dan sanitasi, persyaratan bahan dan pelatihan eksternal. Terdapat bahan yang belum memiliki dokumen pendukung, serta belum ada karyawan yang mengikuti pelatihan eksternal. Hasil penelitian menunjukkan bahwa manual SJH dapat diimplementasikan kecuali pada fasilitas, audit eksternal dan sebagian persyaratan bahan. Berdasakan hal tersebut maka diusulkan perbaikan yaitu melengkapi dokumen pendukung untuk bahan, mengikuti audit eksternal HAS 23 000 dan merancang ulang tata letak ruangan sehingga dapat dilakukan implementasi secara keseluruhan., Warung Sego serves traditional food menus that have never been tested for compliance with sanitation hygiene requirements and HAS 23 000 halal certification requirements so that safety and halalness are not guaranteed. This study aims to apply and maximize all criteria for the Halal Assurance System (SJH) manual and to test the application at Warung Sego. This manual is needed as a technical guide to meet the sanitation and halal hygiene requirements of the products produced. The HAS Manual is compiled based on the real conditions of the Warung Sego restaurant and contains the criteria for implementing the halal guarantee system. The criteria for the Halal Assurance System consist of halal policy, halal management team, training, materials, products, production facilitation, written procedures for critical activities, traceability, handling of products that do not meet the criteria, internal audits, and management reviews. The results showed that during the implementation of the Halal Assurance System Manual there were several unfulfilled criteria, namely production and sanitation facilities, material requirements and external training. There are materials that do not have supporting documents, and there are no employees who have attended external training. The results showed that HAS manual can be implemented except for facilities, external audits and some material requirements. Based on this, improvements are proposed, namely completing supporting documents for materials, following the HAS 23 000 external audit and redesigning the layout of the room so that the overall implementation can be carried out.

Judul: Implementasi Manual Sistem Jaminan Halal dan Higiene Sanitasi di Rumah Makan Angkringan Khas Jogja Mas Bowo Bogor
Abstrak: Angkringan Khas Jogja Mas Bowo merupakan rumah makan yang menyajikan beragam makanan tradisional khas daerah Jogja dan Solo. Rumah makan tersebut belum melakukan sertifikasi halal maupun higiene sanitasi sehingga keamanan dan kehalalan produknya belum terjamin. Oleh karena itu, penelitian ini bertujuan untuk menyusun dan menerapkan sebuah manual Sistem Jaminan Halal bagi Angkringan Khas Jogja Mas Bowo berdasarkan kriteria-kriteria yang terdapat pada Halal Assurance System (HAS) 23 000. Manual SJH merupakan dokumen berisi panduan teknis untuk memenuhi sebelas kriteria sistem jaminan halal yang sesuai dengan kondisi rumah makan. Penelitian diawali dengan melakukan analisis terhadap kondisi umum dan proses bisnis Angkringan Khas Jogja Mas Bowo. Setelah data keadaan lapang rumah makan diketahui, selanjutnya dilakukan penyusunan manual SJH dan implementasinya. Hasil penelitian menunjukkan bahwa manual SJH belum dapat diimplementasikan sepenuhnya karena belum terpenuhinya beberapa kriteria. Kriteria yang belum dapat diimplementasikan di antaranya belum adanya pelatihan eksternal bagi karyawan, belum lengkapnya dokumen pendukung bahan, serta fasilitas sanitasi yang belum lengkap. Berdasarkan kelemahan tersebut, usulan perbaikan yang dapat dilakukan yaitu melakukan pelatihan eksternal HAS 23 000 bagi karyawan, melengkapi dokumen pendukung bahan dan pemasok, dan melengkapi fasilitas sanitasi., Angkringan Khas Jogja Mas Bowo is a restaurant that serves a variety of traditional foods typical of the Jogja and Solo regions. This restaurant does not yet have halal and hygiene sanitation certification so that the safety and halalness of the products are not guaranteed. Therefore, this research is being done to develop and implement a manual for Halal Assurance System based on the criteria contained in the Halal Assurance System (HAS) 23 000. The manual is a document that contains technical guidelines to fulfill the eleven criteria of the Halal Assurance System that are following the real conditions of the restaurant. The study begins by analyzing the general condition and business process at Angkringan Khas Jogja Mas Bowo. After knowing the state of the field, the halal assurance system manual was developed and implemented. The results showed that the HAS manual could not be fully implemented because several criteria had not been fulfilled. The criteria that cannot be implemented include the absence of external training for employees, incomplete supporting documents for materials, and incomplete sanitation facilities. Based on these weaknesses, improvements are proposed, namely by participating in an external training of HAS 23 000, completing supporting documents for materials and suppliers, and sanitation facilities.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
