Judul: Analisis Manajemen Risiko Operasional Koperasi Karanggaan Lembur Mandiri
Abstrak: Di tahun 2020 tercatat jumlah partisipasi masyarakat Indonesia yang tertarik bergabung koperasi hanya sebesar 8.41%. Di samping itu, jumlah koperasi syariah yang berkembang tercatat sejumlah lebih dari 4046. Jumlah tersebut masih sangat sedikit dibandingkan dengan kebutuhan pembiayaan UMKM mencapai 39,72 juta usaha. Salah satu koperasi jasa syariah yang beroperasi saat ini adalah Koperasi Jasa Syariah Karanggaan Lembur Mandiri yang berlokasi di Bekasi. Penelitian ini bertujuan untuk mengidentifikasi risiko operasional. Adapun penelitian ini dilakukan dengan pendekatan kualitatif yaitu dengan metode in-depth interview. Hasil dari penelitian ini yaitu terdapat 25 risiko operasional, diantaranya 3 risiko ekstrim, 7 risiko yang tergolong pada tingkat tinggi dan 15 risiko yang berada pada tingkat sedang., In 2020, it was recorded that the number of Indonesian people who were interested in joining cooperatives was only 8.41%. In addition, the number of developing sharia cooperatives is recorded at more than 4046. This amount is still very small compared to the financing needs of MSMEs reaching 39.72 million businesses. One of the sharia service cooperatives currently operating is the Karanggaan Overtime Mandiri Sharia Services Cooperative located in Bekasi. This study aims to identify operational risk. This research was conducted with a qualitative approach, namely the independent interview method. The results of this study are that there are 25 operational risks, including 3 extreme risks, 7 risks that are classified as high level and 15 risks that are at a moderate level.

Judul: Analisis Kinerja dan Partisipasi Anggota Koperasi Mandiri Jaya Kabupaten Bogor
Abstrak: Koperasi merupakan salah satu lembaga yang dapat menunjang perkembangan agribisnis pedesaan. Peran koperasi dalam sektor pertanian sangat penting, karena kondisi pertanian di Indonesia dicirikan dengan skala usaha yang kecil dan tersebar. Penelitian ini bertujuan untuk menganalisis tingkat kinerja kelembagaan dan partisipasi anggota Koperasi Mandiri Jaya serta menganalisis alternatif strategi perbaikan kinerja Koperasi Mandiri Jaya. Sampel dalam penelitian ini diambil dengan metode purposive sampling dengan jumlah responden sebanyak 30 orang. Penelitian ini menggunakan analisis Penilaian Tangga Perkembangan (PTP) dan korelasi Rank Spearman. Hasil dari penelitian ini menunjukkan bahwa kinerja koperasi berada pada zona hijau yang berarti kinerja koperasi sudah berada dalam kondisi baik. Melalui uji korelasi dengan menggunakan Rank Spearman diperoleh informasi bahwa terdapat hubungan yang searah antara manfaat sosial ekonomi dengan partisipasi anggota pada bidang organisasi, permodalan dan unit usaha.

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.
