Judul: Good Manufacturing Practices and Halal Assurance System Plan of Cake Products from Home Industry
Abstrak: IRTP perlu didorong untuk dapat memenuhi persyaratan regulasi dan pemenuhan kebutuhan konsumen akan pangan yang bermutu, aman dan halal. Magang tugas akhir ini bertujuan mengevaluasi penerapan CPPB-IRT dan menghasilkan manual secara sederhana dalam menyusun rencana SJH dan implementasinya pada produk cakes. Tahapan magang yang dilakukan di IRTP XYZ terbagi menjadi dua prosedur, yaitu prosedur CPPB-IRT dan prosedur SJH. Hasil kegiatan magang ini menunjukkan IRTP XYZ masuk dalam IRTP level IV dalam penerapan CPPB-IRT. Elemen ketidaksesuaian yang harus diperbaiki adalah elemen kritis dan serius. Elemen ketidaksesuaian kritis diantaranya pengondisian tempat sampah, kebersihan karyawan setelah dari toilet, belum memiliki kode produksi, serta penanggung jawab IRTP XYZ belum memiliki sertifikat PKP dan program pelatihan. Sedangkan, elemen ketidaksesuaian serius antara lain tidak tersedia sarana cuci tangan lengkap, toilet terbuka ke ruang produksi, dan karyawan masih mengenakan perhiasan saat produksi. Selain itu, IRTP XYZ telah memiliki manual SJH dan penerapan SJH sudah diterapkan. Kekurangan yang ditemukan adalah belum mengikuti pelatihan eksternal dan dokumen pendukung kehalalan bahan (sertifikat halal) dari sirup ceri sudah kedaluwarsa. Rekomendasi perbaikan untuk penerapan CPPB-IRT ialah memperbaiki elemen ketidaksesuaian kritis dan serius serta registrasi sertifikasi SPP-IRT. Sedangkan Perbaikan SJH dengan mengikuti pelatihan eksternal dan mengganti bahan baku ceri dengan merek lain., Food home industries (IRTPs) need an encouragement to meet the regulation and consumers’ demand on quality, safe, and halal food. This internship project aimed to evaluate the application of GMP and produce a simple manual in preparing a halal assurance system (HAS) plan and its implementation for cake products. The internship stages at IRTP XYZ were divided into two procedures, namely the GMP procedure and the HAS procedure. The results of this internship showed that IRTP XYZ was categorized as level IV in the implementation of GMP. Elements of non-conformance that must be corrected are critical and serious elements. Critical non-conformities elements were the condition of the rubbish bin, the cleanliness of employees after using the toilet, not having a production code, and the person in charge of IRTP XYZ does not have a food safety personal certificate and training program for the employees. Meanwhile, elements of serious non-conformities were not having complete hand washing facilities, toilets open to the production room, and employees still wearing jewelries during production. In addition, XYZ household food industry already had the HAS manual and the HAS implementation has been implemented. The shortcomings found were that they had not attended external training, and the supporting documents for the halal ingredients (halal certificate) from cherry syrup had expired. Recommendations for improvement for the implementation of GMP are fixing critical and serious non-conformities elements and registration for SPP-IRT certification. Meanwhile, the improvement of HAS is done by participating in external training and replacing the raw cherries with other brands.

Judul: The Application of Good Manufacturing Practises and Design of Halal Assurance System Manual at SME’s VRI FOOD
Abstrak: Industri rumah tangga pangan (IRTP) memiliki keterbatasan dalam menghadapi perekonomian global di era perdagangan bebas. IRTP dituntut untuk menghasilkan produk yang bermutu, aman dan berdaya saing tinggi. Pemenuhan izin legal berupa SPP-IRT dan sertifikat halal merupakan salah satu cara agar IRTP mampu memenangkan persaingan pasar dan menjamin keamanan produk yang dihasilkan. Kegiatan penelitian ini bertujuan untuk melakukan evaluasi terhadap pemenuhan kriteria CPPB-IRT termasuk di dalamnya pemenuhan sertifikat penyuluhan keamanan pangan dan label kemasan agar memeroleh SPPIRT serta melakukan implementasi sistem jaminan halal di IRTP VRI FOOD. Kegiatan penelitian ini dibagi menjadi enam tahapan yaitu mengetahui keadaan dan kondisi IRTP VRI FOOD, melakukan perbaikan untuk memenuhi persyaratan CPPB-IRT, melakukan sertifikasi produk minuman jahe instan, menyusun dan mengimplementasikan manual sistem jaminan halal, serta melakukan analisis finansial. Hasil kegiatan penelitian ini menunjukkan IRTP VRI FOOD masuk dalam IRTP level I serta memiliki SPP-IRT dan manual sistem jaminan halal. Selain itu usaha pembuatan jahe instan yang dilakukan oleh IKM VRI FOOD layak untuk dijalankan secara finansial karena nilai NPV (Rp2.223.544)>0, Net B/C (6,09)>1, dan IRR(72%)>DR(14%)., Household Food Industry (IRTP) has limitations in facing the global economy in the era of free trade. IRTPs are required to produce quality, safe, and highly competitive products. Fulfillment of legal permits in the form of SPP-IRT and halal certificates is one way that IRTPs can win the market competition and ensure the safety of the products produced. This research activity aims to evaluate the fulfillment of the CPPB-IRT criteria including the fulfillment of food safety counseling certificates and packaging labels to obtain SPP-IRT and implement a halal guarantee system at IRTP VRI FOOD. This research activity was divided into six stages, namely knowing the state and condition of IRTP VRI FOOD, making improvements to meet CPPB-IRT requirements, certifying instant ginger drink products, compiling and implementing manual halal assurance systems, and conducting financial analysis. The results of this research show that IRTP VRI FOOD is included in the level I IRTP and has an SPP-IRT and manual for the halal assurance system. Also, the instant ginger-making business carried out by IKM VRI FOOD is feasible to run financially because the NPV value (Rp2.223.544)> 0, Net B / C (6,09)> 1, and IRR (72%)> DR (14 %).

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
