Penelitian ini bertujuan untuk menginvestigasi pengaruh pemberian pupuk mikoriza dan pupuk kompos terhadap pertumbuhan dan produksi tanaman pakcoy (Brassica rapa L.). Pada penelitian ini percobaan yang dilakukan terdiri atas 6 perlakuan dengan masing – masing perlakuan diberi 4 pengulanagan. Hasil penelitian menunjukkan bahwa pemberian pupuk mikoriza secara individual meningkatkan pertumbuhan tinggi tanaman dan jumlah daun tanaman sawi pakcoy. Pemberian pupuk mikoriza dan pupuk kompos secara individual meningkatkan pertumbuhan tinggi tanaman pada konsentrasi 20% dan jumlah daun pada konsentrasi 15% dan 30%. Pertumbuhan tanaman ini juga berdampak positif pada peningkatan produksi pakcoy, dengan peningkatan dan hasil yang lebih tinggi.

Bioetika adalah hal yang krusial dalam penelitian dan penggunaan hewan di laboratorium agar sesuai dengan standar kesejahteraan dan etika. Ayam dan telur SPF (Specific Pathogen Free) sangat penting dalam penelitian biomedis karena bebas dari patogen spesifik yang bisa mempengaruhi hasil penelitian. Penelitian ini bertujuan untuk menganalisis penerapan prinsip bioetika dalam pengelolaan dan pemanfaatan ayam SPF serta telur SPF di Laboratorium sebagai media vaksin bebas patogen. Metodologi yang diterapkan dalam penelitian ini adalah studi literatur review dengan menggunakan teknik analisis data yaitu analisis isi (contenct analysis). Hasil penelitian yaitu terdapat prinsip etika ketika hendak melakukan penelitian menggunakan hewan haruslah mengikuti prinsip 3R (replacement, reduction, refinement) dan prinsip 5F (Five freedom). Penggunaan ayam SPF (Specific Pathogen Free) dalam industri peternakan dan produksi vaksin memerlukan perhatian khusus terhadap kesejahteraan hewan.

Fe deficiency in plants results in yellowing of leaves on plants and also reduces the quality of fruit produced. Fe deficiency in plants can be treated by applying slow release fertilizer which will release the nutrients in the fertilizer slowly according to plant needs so that there will be no problem of deficiency or excess of Fe. Activated Carbon/Alginate/Nanocellulose-Fe Composite can be used as slow release fertilizer because this composite releases Fe slowly with citric acid medium and tested with AAS. The functional groups in the Activated Carbon/Alginate/Nanocellulose-Fe Composite showed no disappearance of the functional groups belonging to activated carbon, alginate or nanocellulose so that it can be said that these three components were successfully made into composites and can be carriers of nutrients in micro-fertilizers.

OPEFB is one source of natural fiber-based composites which have the potential to become activated carbon and nanocellulose. This study aims to synthesize and characterize the activated carbon/alginate/nanocellulose-Cu composite. The characterization used in this study is FTIR and PSA. The synthesis of activated carbon/alginate/nanocellulose-Cu composites began with a process of carbonization and activation with H3PO4 to produce Activated Carbon. Followed by a bleaching process with NaClO2 and a delignification process with Na2SO3 and NaOH to produce Nanocellulose. Alginate using commercial alginate. Furthermore, the three ingredients were mixed until homogeneous and put into a 0.1M CuSO4 solution to produce beads. The results of the characterization of characterization of PSA Nanocellulose obtained a particle size of 41.05 nm and the result of FTIR characterization on the activated carbon/alginate/nanocellulose-Cu composite contained the functional group OH group, triple C bond from stretching alkyne, C=C aromatic group, C-H alkane group, C-O group, the P=O stretching vibration of the P-O-C group and the alcohol OH group expressing the active carbon; there are functional groups of hydroxyl (OH), carboxyl, carbonyl, and C-O-C and –COOH bonds which represent alginate and there are OH functional groups, stretching C-H bonds, C-O stretching, stretching C-C, and β- glucosidic bonds between glucose units which indicate nanocellulose.

This study aims to determine the adsorption equilibrium of the activated carbon of empty palm oil fruit bunches and KA-Cu(TAC) on Zn(II). Oil palm empty fruit bunches are used as a bio-sorbent in making carbon at a temperature of 5000 C, the resulting carbon is activated using H3PO4 and modified into a composite with metal organic frameworks of Cu metal and terephthalic acid. MOFs and KA-Cu(TAC) composites were produced by reflux method. Activated carbon, MOFS and KA-Cu(TAC) were characterized using XRD. The adsorption process of Zn(II) metal was analyzed using AAS and determined the optimum conditions with various concentrations to determine the adsorption equilibrium. XRD characterization results show that activated carbon has an amorphous structure, while MOFs Cu(TAC) and KA-Cu(TAC) have a crystalline structure. The optimum condition of activated carbon and KA-Cu(TAC) at a concentration of 180 ppm with the appropriate adsorption isotherm model is the Langmuir isotherm.

Research on the slow release kinetics of Fe(III) ions from Activated Carbon/Alginate-Fe(III) composites or abbreviated as K/A-Fe(III) has been carried out. The aim of this research was to synthesize K/A-Fe(III) composite as a material that has the potential to become a slow release micronutrient fertilizer and to study the kinetics of slow release of Fe(III) ions from the composite. The K/A-Fe(III) composite was synthesized by mixing alginate suspension and activated carbon (alginate: activated carbon weight ratio = 1:3 and 3:1) until homogeneous. Composite grains were characterized using Fourier Transformed Infrared (FTIR) spectroscopy, the kinetics of Fe(III) release from the three composite variations found that KAlg31 composite showed more absorption and release of Fe ions than KAlg13.

Abstract Food safety is an important aspect in public health, especially in preventing foodborne diseases. This study aims to analyze pathogenis microbial contamination in several food samples such Dried Anchovy, Dried Shrimp dan Brownies. The test methods used include otal plate count (measuring the total number of microbes in the sample), Most Probable Number (MPN) to detect Escherichia coli, Staphylococcus aureus test and Salmonella test. The results showed that all food samples tested were still within the safe limits set by the Indonesian National Standard (SNI) and the Food and Drug Administration (BPOM) so they were suitable for consumption. Therefore, this study emphasizes the importance of microbiological monitoring and testing in ensuring food safety to prevent health risks due to pathogenic microbial contamination. Abstrak Kemanan pangan merupakan aspek penting dalam kesehatan masyarakat terutama dalam mencegah penyakit akibat pangan (Foodborne Diseases). Penelitian ini bertujuan untuk menganalisis cemaran mikroba patogen pada beberapa sampel pangan seperti Dried Anchovy, Dried Shrimp dan Brownies. Metode pengujian yang digunakan meliputi angka lempeng total (mengukur jumlah keseluruhan mikroba dalam sampel), Most Probable Number (MPN) untuk mendeteksi Escherichia coli, uji Staphylococcus aureus dan uji Salmonella. Hasil penelitian menujukkan bahwa seluruh sampel pangan yang diuji masih berada dalam batas aman yang ditetapna oleh Standar Nasional Indonesia (SNI) dan Badan Pengawas Obat dan Makanan (BPOM) sehingga layak untuk dikonsumsi. Oleh karena itu, penelitian ini menegaskan pentingnya pengawasan dan pengujian mikrobiologis dalam memastikan keamanan pangan untuk mencegah risiko kesehatan akibat kontaminasi mikroba patogen.
