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: 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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
