Judul: Faktor-faktor yang mempengaruhi pengetahuan, sikap, dan keterampilan kader tentang modul dasar pada posyandu berhasil dan kurang berhasil : Studi kasus di Keluarahan Cikole, Kelurahan Selabatu, dan Kelurahan Kebon Jati, Kecamatan Cikole, Kotamadya Sukabumi
Abstrak: Tujuan penelitian ini adalah mengetahui faktor-faktor yang mempengaruhi pengetahuan, sikap, dan keterampilan (PSK) kader tentang modul dasar serta bagaimana perbedaan PSK tersebut antara Posyandu yang berhasil dan kurang berhasil. Secara khusus penelitian ini bertujuan untuk mengetahui PSK kader tentang modul dasar pada Posyandu yang berhasil dan kurang berhasil, mengetahui pengaruh faktor karakteristik demografi (umur, status pernikahan, jumlah anggota keluarga, jumlah anak, dan keberadaan balita), faktor sosial ekonomi (tingkat pendidikan, status pekerjaan, pekerjaan suami/KK, dan tingkat pendapatan), dan faktor pengalaman selama menjadi kader (lama menjadi kader, keikutsertaan dalam pelatihan dan supervisi, sarana, dan insentif), mengetahui hubungan antara PSK kader tentang modul dasar, dan tingkat partisipasi masyarakat dengan keberhasilan Posyandu.

Judul: Hubungan Sikap dan Motivasi Kerja dengan Kinerja Kader Posyandu (Kasus: Desa Coper dan Desa Kutuwetan, Kecamatan Jetis, Kabupaten Ponorogo, Jawa Timur).
Abstrak: Pembangunan kesehatan merupakan hal yang penting dalam membangun kualitas manusia di suatu negara salah satunya dengan melakukan pelayanan kesehatan berbasis partisipasi masyarakat. Sikap kader terhadap kegiatan-kegiatan Posyandu mencakup aspek kognisi, afeksi, dan konasi. Aspek motivasi kerja mencakup motivasi eksternal dan internal. Sikap dan motivasi kerja ini akan dihubungkan dengan kinerja kader Posyandu seperti kerjasama, pemanfaatan waktu, tingkat kehadiran, kualitas kerja, dan kuantitas kerja. Tulisan ini bertujuan untuk mengetahui hubungan sikap dan motivasi dengan kinerja kader. Penelitian ini menggunakan pendekatan kuantitatif yang didukung dengan data kualitatif. Metode yang digunakan dalam penelitian ini adalah metode survey dengan responden sebanyak 35 orang. Hasil penelitian ini menunjukkan, terdapat hubungan signifikan antara sikap dengan motivasi kerja kader sebesar 0,390 serta hubungan antara sikap denga kinerja sebesar 0,322 dan terdapat hubungan antara motivasi kerja dengan kinerja sebesar 0,375.

Judul: Extracellular Expression of thermostable Geobacillus stearothermophilus T1.2RQ Lipase for Biodiesel Production
Abstrak: The extracellular expression of enzymes in an excellent secretion host such as Bacillus subtilis is a useful strategy for making enzymes of industrial significance more affordable by lowering the cost of its downstream processing. Lipases are a category of hydrolases that catalyze the hydrolysis of triglycerides to glycerol and free fatty acids. Also, lipases catalyze the hydrolysis and transesterification of other esters as well as the synthesis of esters. They can perform very specific biotransformation reactions and are widely used in food, organic synthesis, detergents, cosmetic, and pharmaceutical industries. Geobacillus stearothermophilus T1.2RQ lipase is an industrially-desired thermostable lipolytic enzyme with an excellent hydrolytic and transesterification activity. This study aimed to express T1.2RQ lipase, in B. subtilis WB800 and ensure its secretion into the extracellular medium. Three signal peptides (AmyQ, Epr, LipA) and two promoters (Pgrac01 and Pgrac100) were used in the secretory-expression of T1.2RQ lipase, based on five constructed expression vectors constructed by restriction cloning and PCR mutagenesis. Sangers sequencing was used to verify constructs to ensure they are in the correct reading frame. Recombinants vectors, pHT43 (plasmid control), pHT43-T1.2RQ, pHT43- T1.2RQ_AmyQ, pHT43-T1.2RQ_Epr, and pHT43-T1.2RQ_LipA, were transformed by electroporation into Bacillus subtilis WB800. The electroporation was successful with the optimum condition of 2500V, 200 ohms, 25µF, and 5milliseconds. Recombinant B. subtilis pHT43 (negative control) and pHT43-T1.2RQlip + signal peptides were streaked on the lipidic agar, LA+TBN. All four recombinants, including the negative control (B. subtilis WB800-pHT43), produced clear zones on the TBN agar plate after overnight incubation (fig 2), indicating the presence of a lipolytic enzyme in all of the recombinant B. subtilis cells. pHT43-T1.2RQlip + signal peptides (AmyQ, Epr, and LipA) have clear zones with significantly higher diameters than B. subtilis WB800-pHT43 (negative control). This phenomenon suggests that the recombinant thermostable lipase T1.2RQ introduced into these cells was successfully expressed, thereby increasing the lipolytic capability of its host cells T1.2RQ lipase was expressed in 50ml terrific broth medium (TB) and the expression induced with 1mM IPTG. Lipase activity assay using p-nitrophenyl esters showed that all three signal peptides directed the secretion of T1.2RQ lipase into the extracellular medium. Signal peptide, LipA, resulted in the highest extracellular activity of 5.6 U/mL, which corresponds to a 6-fold increase over the parent B. subtilis WB800 strain. Meanwhile, signal peptides, AmyQ and Epr produced 4.2 U/mL and 3.4 U/mL activity respectively. SDS-Zymogram analysis confirmed that T1.2RQ lipase was correctly processed and secreted in its original size of 44 kDa. An attempt to further increase lipase expression level by promoter optimization showed that, contrary to expectation, promoter Pgrac100 exhibited similar expression levels as the original Pgrac01. Nevertheless, the demonstration of the successful secretion of T1.2RQ lipase in this work confirms the latter as a promising approach for the industrial production of the enzyme
