Judul: Perkiraan Kehilangan Pangan (Food Loss dan Food Waste) Komoditas Beras di Indonesia
Abstrak: Tujuan dari penelitian ini adalah untuk untuk memperkirakan besarnya food loss dan food waste komoditas beras di Indonesia. Desain penelitian yang digunakan adalah analisis deskriptif kuantitatif. Penelitian dilakukan dengan mengolah data sekunder yang berkaitan dengan food loss dan food waste komoditas beras di Indonesia dengan menggunakan formula tertentu. Pengolahan data dilakukan di Bogor, Jawa Barat, pada bulan Februari – April 2016.Food loss komoditas beras yang diperkirakan besarnya pada penelitian ini meliputi tahapantahapan pemanenan, perontokan, pengeringan, dan tahapan penggilingan serta tahapan distribusi.Food waste komoditas beras meliputi food waste yang terdapat pada tingkat rumah tangga, restoran, dan rumah sakit di Indonesia. Hasil dari penelitian ini adalah sebesar 23.92% atau hampir ¼ beras yang diproduksi di Indonesia loss dan waste. Hal tersebut menyebabkan kerugian ekonomi senilai 86.6 triliun rupiah dan kehilangan zat gizi berupa energi sebesar 395 kkal/kap/hari dan protein sebesar 7.46 gram/kap/hari protein, serta kerugian di bidang lingkungan berupa pemborosan sumber daya alam seperti air dan udara.

Judul: Estimated of Economic Losses and Community Behavior on Household Rice Food Waste (Case Study: Cikupa District, Tangerang Regency)
Abstrak: Food waste merupakan makanan layak konsumsi yang mengalami pembuangan di tingkat konsumen, baik sebelum atau sesudah masa kedaluwarsa. Salah satu jenis food waste yang dihasilkan adalah beras. Peningkatan food waste beras menyebabkan kerugian terhadap ketahanan pangan, pemborosan ekonomi dan pencemaran lingkungan. Kecamatan Cikupa merupakan salah satu wilayah sebagai sumber penghasil sampah terbesar kedua di Kabupaten Tangerang, Provinsi Banten. Permasalahan sampah rumah tangga di Kecamatan Cikupa yaitu sampah dibuang tanpa proses pemilahan, tidak ada pengelolaan sampah secara berkelanjutan, serta penimbunan dan pembakaran sampah di lahan terbuka. Tujuan penelitian untuk menghitung nilai kerugian ekonomi akibat food waste beras, menganalisis faktor penyebab, dan mengkaji strategi pengelolaan food waste beras rumah tangga. Metode yang digunakan yaitu SNI 19-3964-1994, damage cost, benefit transfer, metode regresi logistik, dan analytical hierarchy process (AHP). Hasil penelitian menunjukkan bahwa food waste beras di Kecamatan Cikupa menyebabkan kerugian ekonomi sebesar Rp25.637.901.552 per tahun dan kerugian lingkungan sebesar Rp43.186.964.681 per tahun. Faktor penyebab food waste beras adalah harga beras, selera, pengetahuan, kesehatan dan umur. Strategi pengelolaan food waste beras dapat diimplementasikan dengan meningkatkan kualitas sumber daya manusia (SDM) melalui kegiatan pemanfaatan sampah menjadi pupuk dan pakan ternak., Food waste is referred to edible food that is thrown away by the people, either before or after the expired time. Rice is one of the common food waste products. The increase in rice food waste causes losses to food security, economic waste and environmental problem. Cikupa sub-district is the second largest waste producer in Tangerang Regency, Banten Province. The problem of household waste in Cikupa District is disposing of waste without a sorting process, there is un sustainable waste management, as well as landfilling and burning waste in open area. The aims of this study are to calculate the value of economic and environmental losses due to rice food waste, to analyze the causal factors, and to examine sustainable food waste management strategies. The method used are SNI 19-3964-1994, damage cost, benefit transfer, logistic regression method, and analytical hierarchy process. The results showed that rice food waste in Cikupa District caused economic losses of Rp25.637.901.552/year and environmental losses of Rp43.186.964.681/year. Generated food waste are driven by the price of rice, tastes, knowledge, habits, health and age. Food waste management strategies can be implemented by improving the quality of human resources (HR) through educational to process waste into fertilizer and feed animal.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
