Penelitian ini bertujuan untuk mengetahui tingkat pengetahuan dan faktor yang mempengaruhi pengetahuan pelaku usaha mikro kecil di Kecamatan Bogor Utara terhadap halal self declare. Data diperoleh dari hasil menyebarkan kuesioner, observasi dan wawancara, dan data tersebut dianalisis menggunakan analisis deskriptif dan analisis regresi logistik. Hasil penelitian ini menunjukkan bahwa tingkat pengetahuan pelaku usaha mikro dan kecil di Kecamatan Bogor Utara masih sangat rendah. Hasil analisis regresi logistik menunjukkan bahwa variabel pengetahuan halal, networking, sosialisasi, pendidikan terakhir, dan skala usaha berpengaruh signifikan terhadap tingkat pengetahuan pelaku usaha mikro dan kecil terhadap Halal Self Declare di Kecamatan Bogor Utara., Based on PP No. 39 of 2021, one way to carry out halal certification for Micro and Small Enterprises (UMK) is to halal self declare. This study aims to determine the level of knowledge and factors that influenced micro small business owners in North Bogor District against halal self declare. The data were taken from questionnaires, observations and interviews, and were analyzed using descriptive analysis and logistic regression analysis. The results of this study indicate that the level of knowledge of micro and small business actors in North Bogor District is still very low. The results of logistic regression analysis show that the variables of knowledge, networking, socialization, education, and business scale have a significant effect on the level of knowledge of micro and small enterprise on halal self declare in North Bogor District.

Judul: Niat dan Perilaku Pelaku Usaha Mikro dan Kecil
(UMK) Terhadap Halal Self Declare (Studi Kasus: Halal Science Center IPB).
Abstrak: Berdasarkan Peraturan Pemerintah nomor 39 tahun 2021, halal self declare adalah skema pengajuan sertifikasi halal bagi UMK dengan produk berbahan baku bukan daging. Penelitian ini bertujuan untuk menganalisis karakteristik dan faktor-faktor yang memengaruhi niat dan perilaku pelaku UMK terhadap halal Self Declare. Model acuan dalam penelitian ini menggunakan theory of planned behavior (TPB) yang telah dimodifikasi. Penentuan responden dalam penelitian ini menggunakan teknik purposive sampling. Populasi responden merupakan semua pelaku UMK yang sudah memiliki sertifikat halal melalui Halal Science Center (HSC) IPB. Pengumpulan data dari responden menggunakan kuesioner yang disebarkan secara langsung dan dianalisis menggunakan analisis deskriptif dan SEM-PLS. Hasil penelitian menunjukkan bahwa variabel attitude, kesadaran halal, dan religiusitas berpengaruh positif dan signifikan terhadap niat halal self declare. Variabel yang berpengaruh positif dan signifikan terhadap perilaku self declare adalah perceived behavioral control dan niat halal self declare., Based on Government Regulations number 39 of 2021, halal self declare is a scheme for applying a halal certification for MSEs with products made from non-meat raw materials. This research aims to analyze the characteristics and factors which influence the intention and behavior of SMEs toward halal self declare. A modification reference model from the theory of planned behavior is applied in this research. In this study, the respondents were determined using a purposive sampling technique. The respondent population were all MSE actors who already had halal certificates through Halal Science Center (HSC) IPB. Data collection from respondents using questionnaires distributed directly and analyzed using descriptive analysis and SEM-PLS. The results showed that the variables of attitude, halal awareness, and religiosity had a positive and significant effect on halal self declare intentions. The variables that have a positive and significant effect on halal self declare behavior are perceived behavioral control and halal self declare intention.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
