Penelitian ini bertujuan untuk melihat pengaruh penerapan akuntansi pertanggungjawaban sebagai alat ukur kinerja manajer pada KSU Dhanadyaksa Jatim tahun 2012-2014. Jenis penelitian ini adalah deskriptif kualitatif dan deskriptif kuantitatif. Populasi dalam penelitian ini yaitu 105 anggota aktif KSU Dhanadyaksa Jatim. Penarikan sampel dilakukan dengan menggunakan Purpossive Sampling. Jumlah sampel minimal sebesar 80 sampel. Kategori responden yang diteliti, ditentukan minimal responden berpendidikan SMA keatas, dan hanya 43 kuesioner yang layak dan memenuhi syarat dengan berpendidikan minimal SMA untuk diteliti lebih lanjut. Teknik pengumpulan data dalam penelitian ini yaitu menggunakan kuesioner, wawancara, dokumentasi dan studi kepustakaan. Definisi operasional yang digunakan dalam penelitian ini adalah akuntansi pertanggungjawaban (X) dan kinerja manajer (Y). Hasil penelitian menunjukkan bahwa Akuntansi pertanggungjawaban pada KSU Dhanadyaksa sudah baik dilihat dari syarat-syarat akuntansi pertanggungjawaban yang telah diterapkan. Sedangkan kinerja manajer berdasarkan karakteristik akuntansi pertanggungjawaban pada KSU Dhanadyaksa Jatim bisa dikatakan belum berjalan dengan optimal. Hal tersebut dapat dilihat dari pusat pertanggungjawaban telah dilaksanakan namun manajer bertanggungjawab atas seluruh pusat-pusat pertanggungjawaban tersebut. Standar realisasi pinjaman merupakan tanggungjawab manager secara penuh, sedangkan marketing lebih ditekankan untuk mengatasi kredit macet pada anggota. RAPB yang dibebankan kepada manajemen dari tahun 2012 sampai 2014 realisasi pendapatan KSU Dhandyaksa Jatim tidak mencapai target. Sedangkan untuk biaya KSU Dhandyaksa Jatim dari tahun 2012 sampai 2013 hampir selalu tidak dapat terealisasi. Pemberian penghargaan belum diterapkan secara optimal dan menyeluruh dan hanya diberikan kepada manajer saja. Sedangkan hukuman yang pernah diberikan kepada karyawan yaitu teguran dan surat peringatan, Variabel akuntansi pertanggungjawaban berpengaruh positif dan signifikan terhadap kinerja manajer.

Co-sensitization of natural dyes on TiO2 for dye-sensitized solar cell (DSSC) was proposed between chlorophyllin (C) and xanthophylls (X at various volume ratios of C/X. Chlorophyllin is chlorophyll derivative providing -COOH groups essential for binding to TiO2. The chlorophyll was extracted from dried spinach (amaranthus viridis) leaves in a mixture of methanol-acetone (70%:30%). Chlorophyll extract dye was obtained after partition of the crude extracts in diethyl ether solution. Then, it was hydrolyzed under alkaline condition to get chlorophyllin. Xanthophyll was extracted from fresh petal of chrysanthemum (chrysanthemum indicum) flowers. Blending of chlorophyllin and xanthophyll was carried out at various volume ratios of C to X (1:0, 5:1, 1:1, 1:5, 0:1). Titania solar cells were constructed in sandwich system of conducting glass-titania/dyes as the photoanode and conducting glass-platinum as the photocathode. Electrolyte solution containing I-/I3- was inserted between the electrodes by capillary action. All dye extracts and blending solutions were analyzed by UV-Vis spectrophotometer. It is shown that the absorption spectra of blending dyes are complimentary in the visible region resulted in a panchromatic response of the dyes. From the cyclic voltammogram of the dyes and blended-dyes, it is found that the energy level of xanthophyll is the lowest. The I-V test at 100 mw/cm2 irradiation confirmed that the energy conversion efficiency (h) of the blended dyes of xanthophyll and chlorophyllin-sensitized solar cell resulted in significant improvement than those of the single dye. Beneficially, the mixed dyes can be adsorbed from solution blend using single dipping step.

AbstractBasal stem rot (BSR) disease caused by Ganoderma sp. is a major disease in oil palm. One of the keys to successfully control BSR disease is to detect the pathogenic infections as early as possible. Early detection technique has been developed in this study was using volatile compounds sensors known as an electronic nose, specifically Electronic Nose 118. Plant samples were obtained from roots, stems, leaves, and soils of four plant categories, which were midly, moderately, and severely infected by Ganoderma, and healthy plants. The test results showed that Electronic Nose was able to record the profile of volatile organic compounds (VOC) produced by Ganoderma sp. The Linear Discriminant Analysis (LDA) results showed that the root and stem samples were differentiated in fairly high level of discrimination with values of 89.66% and 94.59% respectively, while for internal validation value were 98.18% and 89.18%. However, for leaf and soil samples, Electronic Nose 118 resulted in low discriminations. The test results show that Electronic Nose 118 can distinguish samples of roots and stems of healthy plant and Ganoderma-infected plant with a high accuracy.[Keywords: Ganoderma, linier discriminant analysis (LDA), pathogen infection, sensor, volatile organic compound] AbstrakPenyakit busuk pangkal batang (BPB) yang disebabkan oleh Ganoderma sp. merupakan penyakit utama pada kelapa sawit. Salah satu kunci keberhasilan pengendalian penyakit BPB adalah diketahuinya infeksi patogen sedini mungkin. Teknik deteksi dini yang saat ini dikembangkan dalam penelitian ini adalah menggunakan sensor senyawa volatil yang dikenal dengan electronic nose, khususnya Electronic Nose 118. Sampel tanaman diperoleh dari akar, batang, daun, dan tanah dari empat kondisi tanaman, yaitu tanaman yang terinfeksi Ganoderma ringan, sedang, berat dan tanaman sehat. Hasil pengujian menunjukkan bahwa profil senyawa organik volatil yang dihasilkan oleh infeksi Ganoderma sp. dapat ditangkap oleh Electronic Nose 118 dengan baik. Hasil analisis Linear Discriminat Analysis (LDA) menunjukkan bahwa sampel akar dan batang terbedakan dengan tingkat diskriminasi yang cukup tinggi dengan nilai secara berurutan yaitu 89,66% dan 94,59%, sedangkan untuk validasi internal masing-masing 98,18% dan 89,18%. Namun demikian, untuk sampel daun dan tanah, pengujian dengan Electronic Nose 118 menghasilkan tingkat diskriminasi yang rendah. Hasil pengujian menunjukkan Electronic Nose 118 dapat membedakan sampel akar dan batang dari tanaman sehat dan tanaman terserang Ganoderma dengan akurasi tinggi.[Kata kunci : Ganoderma, LDA, infeksi patogen, sensor, senyawa organik volatil]

This research aims to explore project-based learning models in 21st century health education, with a focus on improving collaboration and problem-solving skills. Through a systematic literature review covering 15 research journals published between January 2020 and January 2024, it was found that project-based learning significantly improved students' global health competencies. Results showed improvements in communication and problem-solving skills, reflecting progress in students' capacity to think critically and collaborate in the context of global health issues. Although the results are positive, challenges such as inadequate teacher training and limited resources must be overcome to maximize the benefits of this learning model. This research provides important insights for educators and policy makers in implementing project-based learning in health education.
