Judul: Factors that Influence Participation in Halal Self Declare in Baleendah District
Abstrak: Halal self declare merupakan dukungan pemerintah bagi usaha mikro dan kecil (UMK) agar memiliki daya saing dalam industri halal. UMK mendapat perhatian khusus karena terbukti memiliki dampak signifikan bagi perekonomian Indonesia. Kendati demikian, halal self declare masih belum maksimal dimanfaatkan. Per Mei 2023, program sertifikasi skema self declare tahap ketiga baru mencapai 8,9% dari 1 juta target. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keikutsertaan dalam halal self declare di Kecamatan Baleendah. Kecamatan Baleendah dipilih karena merupakan kecamatan dengan populasi dan penduduk muslim terbanyak di Kabupaten Bandung. Data dianalisis menggunakan analisis deskriptif dan regresi logistik. Hasil analisis regresi logistik menunjukkan variabel religiusitas, sosialisasi, dan bantuan berpengaruh positif signifikan, sementara variabel lama usaha memiliki pengaruh signifikan yang negatif terhadap keikutsertaan halal self declare UMK. Implikasi kebijakan yang dapat dilaksanakan adalah mendorong lebih banyak sosialisasi, bantuan, serta pemberlakuan teguran bagi UMK yang belum melaksanakan halal self declare., Halal self declare represents government support for micro and small enterprises (SMEs) to enhance their competitiveness in the halal industry. SMEs receive special attention due to their significant impact on Indonesia's economy. However, the utilization of halal self declare remains suboptimal. As of May 2023, the third halal self declare certification program had only reached 8.9% of its 1 million targets. This research aims to analyze the factors influencing participation in halal self declare in the Baleendah district. Baleendah district was chosen because it has the largest Muslim population in Bandung Regency. Data were analyzed using descriptive analysis and logistic regression. The logistic regression analysis results indicated that religiosity, socialization, and assistance variables had a significant positive impact, while the variable length of business had a significant negative impact on SMEs participation in halal self declare. Policy implications that can be implemented include increasing socialization, assistance, and the implementation of warnings for SMEs that have not yet implemented halal self declare.

Judul: The Level of Knowledge of Micro and Small Enterprise on Halal Self Declare in North District
Abstrak: Berdasarkan PP no 39 Tahun 2021 salah satu cara melakukan sertifikasi halal untuk Usaha Mikro Kecil (UMK) adalah dengan halal self declare. 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: 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.
