Judul: Development of Guidelines (Code of Practice) for Inspection of Processing Facilities for Palm Cooking Oil
Abstrak: Minyak goreng sawit merupakan minyak pangan yang berasal dari buah kelapa sawit dan biasa digunakan sebagai bahan menggoreng bagi sebagian besar masyarakat Indonesia. Produksi minyak goreng sawit harus mempertimbangkan aspek keamanan pangan agar aman sampai di tangan konsumen. Meninjau Permenperin Nomor 46 tahun 2019 dan PerBPOM Nomor 22 tahun 2021 mengenai Pemberlakuan SNI wajib minyak goreng sawit dan Izin CPPOB sarana produksi. Implementasi tersebut dengan adanya pengawasan keamanan pangan berbasis risiko telah menjadi tugas BPOM untuk menyusun pedoman pemeriksaan yang efektif sehingga dapat memenuhi tugas pengawasan post-market dan penerbitan izin CPPOB. Kegiatan magang ini bertujuan mengkaji rancangan pedoman inspeksi sarana pengolahan minyak goreng sawit dengan melakukan pengembangan terhadap regulasi dan informasi yang mendukung dalam penyusunan pedoman inspeksi. Hasil analisis perbandingan terhadap aturan yang ada di Indonesia dan internasional seperti Codex dan FAO (Food and Agriculture Organization) memiliki persamaan maupun perbedaan dalam spesifikasinya serta kemiripan antara SNI (Standar Nasional Indonesia) dan MS (Malaysian Standard). Standar internasional tersebut digunakan untuk mengisi kekosongan regulasi dengan mengadopsi beberapa peraturan nasional. Studi pustaka terhadap aspek proses dan pengendalian dilakukan untuk melengkapi informasi terkait pengolahan dan aspek pengendalian khusus terhadap minyak goreng sawit yang harus dipertimbangkan saat pengawasan sarana produksi minyak goreng sawit., Refined palm oil is a food oil derived from oil palm fruit and is commonly used as a frying ingredient for most Indonesians. The production of palm cooking oil must consider aspects of food safety so that it reaches consumers safely. Reviewing Permenperin number 46 of 2019 and PerBPOM number 22 of 2021 concerning Enforcement of mandatory SNI for palm cooking oil and CPPOB permits for production facilities. This implementation with risk-based food safety supervision has become the task of BPOM to develop effective code of practice so that they can meet national standards. This internship activity aims to review the draft guidelines for inspection of palm cooking oil processing facilities by developing regulations and supporting information in the preparation of inspection guidelines. The results of the comparative analysis of existing regulations in Indonesia and internationally such as Codex and FAO have similarities and differences in their specifications and the similarity between SNI (Standar Nasional Indonesia) and MS (Malaysian Standard). These international standards are used to fill the regulatory gap by adopting several national regulations. Literature study on process and control aspects was conducted to complete information related to processing and specific control aspects of palm cooking oil that must be considered when supervising palm cooking oil production facilities.

Judul: Kajian Penerapan Produksi Bersih pada Agroindustri Minyak Goreng Kelapa (Studi Kasus di Koperasi Wanita Srikandi)
Abstrak: Penerapan produksi bersih pada agroindustri minyak goreng kelapa dilakukan untuk meminimalkan limbah dan mencegah kehilangan sumber daya. Penelitian ini bertujuan mengkaji peluang produksi bersih pada proses produksi minyak goreng kelapa. Tahapan penelitian mencakup analisis quick scan, identifikasi aliran material, energi dan limbah, penentuan alternatif produksi bersih, analisis kelayakan teknis, lingkungan dan finansial berupa benefit cost ratio (B/C ratio) serta payback period (PP), penentuan prioritas penerapan produksi bersih dengan metode perbandingan eksponensial. Rantai proses terdiri dari pembuatan minyak klentik di tingkat pemasok, kemudian dilanjutkan menjadi minyak goreng kelapa di tingkat pabrik. Alternatif produksi bersih pada tingkat pemasok adalah: (1) pengolahan nata de coco (B/C ratio 1,17 dan PP 0,74 tahun), (2) pengolahan pupuk kompos (B/C ratio 1,26 dan PP 0,29 tahun), serta (3) pembuatan maggot (B/C ratio 1,75 dan PP 0,45 tahun). Alternatif produksi bersih pada tingkat pabrik adalah: (1) penjadwalan produksi (B/C ratio 170 dan PP 0,05 bulan), (2) perbaikan SOP penuangan minyak (B/C ratio 4,55 dan PP 0,01 tahun), (3) water recycle (B/C ratio 2,99 dan PP 4,23 tahun), dan (4) penggantian instalasi pipa (B/C ratio 3,95 dan PP 0,05 tahun). Prioritas alternatif yang direkomendasikan pertama pengolahan pupuk kompos untuk tingkat pemasok dan penjadwalan produksi untuk tingkat pabrik., The application of cleaner production in the coconut cooking oil agroindustry carried out to minimize waste and prevent resources lost. This study aims to examine the opportunities for cleaner production in the process of coconut cooking oil. Research stages included quick scan analysis, identification of material flow, energy and waste, determination of cleaner production alternatives, technical, environmental and financial feasibility analysis as benefit cost ratio (B/C ratio) and payback period (PP), and determining priorities for the application of cleaner production with the exponential comparison method. The process chain consists of the crude coconut oil production at supplier level, then continuing into the coconut cooking oil at factory level. Alternative cleaner production at the suppliers level is (1) nata de coco processing (B/C ratio 1.17 and PP 0.74 years), (2) composting (B/C ratio 1.26 and PP 0.29 years), and (3) maggot production (B/C ratio 1.75 and PP 0.45 years). Alternative cleaner production at the factory level is (1) production scheduling (B/C ratio 170 and PP 0.05 months), (2) improvement in oil pouring techniques (B/C ratio 4.55 and PP 0.01 years), (3) water recycle (B/C ratio 2.99 and PP 4.23 years), and (4) pipe installation replacement (B/C ratio 3.95 and PP 0.05 years). The first recommended alternative priority was compost processing for supplier level and production scheduling for factory level.

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.
