Judul: Analysis the Cost and Nutrients of Food Waste Inpatients at UPTD RSUD Bangka Tengah
Abstrak: Salah satu indikator pelayanan makanan rumah sakit adalah persentase sisa makanan pasien ≤20%. Dampak sisa makanan mengakibatkan biaya yang terbuang dan asupan gizi pasien menjadi tidak adekuat. Penelitian dilakukan pada pasien rawat inap UPTD RSUD Bangka Tengah menggunakan metode penelitian cross sectional dengan subjek 48 orang. Hasil penelitian menunjukkan bahwa sisa makanan memenuhi indikator pelayanan gizi (<20%). Rata-rata biaya yang terbuang sebagai sisa makanan per pasien adalah Rp 790,79 per hari atau Rp 284.684,4 per tahun. Zat gizi dalam sisa makanan sebesar 68,73 kalori; protein 2,57 gr; lemak 2,47 gr dan karbohidrat 9,39 gr. Hasil penelitian menunjukkan bahwa terdapat hubungan yang signifikan antara sisa makanan dengan jenis kelamin (p=0,001) dan sisa makanan dengan kelas perawatan (p=0,002). Tidak terdapat hubungan yang signifikan antara sisa makanan dengan usia (p=0,605); sisa makanan dengan jenis perawatan (p=0,388) dan sisa makanan dengan jenis diet (p=0,975)., One of hospital food service indicators is the patient's food waste percentage ≤20%. The impact of food waste results in wasted costs and inadequate nutritional intake of patients. The research was inpatients at UPTD RSUD Bangka Tengah used a cross sectional research method with 48 subjects. The results showed that food waste according to indicator (<20%). The cost average of food waste per patient was Rp 790,79 per day or Rp 284.684,4 per year. Nutrients of food waste were 68,73 calories; protein 2,57 gr; fat 2,47 gr and carbohydrates 9,39 gr. The result showed that there was a significant correlation between food waste with gender (p=0,001) and food waste with inpatient class (p=0,002). There was not significant correlation between food waste with age (p=0,605; food waste with type of hospital care (p=0,388) and food waste with type of diet (p=0,975).

Judul: Cost Analysis of Food Waste and Food Acceptance Inpatient in RSUDZA Banda Aceh
Abstrak: Penelitian ini bertujuan menganalisis biaya sisa makanan dan daya terima makanan pada pasien rawat inap di RSUDZA Banda Aceh. Desain penelitian yang digunakan yaitu cross sectional study dengan jumlah subjek 47 pasien selama 10 hari. Data karakteristik pasien, daya terima makanan, dan data konsumsi makanan luar rumah sakit didapatkan melalui wawancara menggunakan kuesioner dan data sisa makanan pasien diperoleh melalui metode Comstock. Hasil penelitian menunjukkan bahwa rata-rata sisa makanan pasien yaitu sebesar 27,9% dengan biaya rata-rata sisa makanan dalam sehari adalah Rp24.264 per pasien per hari atau sebesar 28,5% dari total biaya makan. Hasil penelitian menunjukkan bahwa terdapat hubungan yang signifikan (p<0,05) antara kondisi fisik dan daya terima dengan sisa makanan pasien., The aim of this study was to analyse the cost of food waste and sensory characteristics of food inpatient in RSUDZA Banda Aceh. The research design was cross sectional study with 47 subject during 10 days. Characteristic subject, food acceptance and consumption of food from outside the hospital were collected by interview using questionnaire and sample of food waste obtained by Comstock methods.The result showed that the average of patients food waste was 27,9% with the average cost was Rp24 264 per patient per day or 28,5% of food cost. The result showed that there was a significant correlation (p<0,05) between physical condition and food acceptance with food waste.

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
