Logam merupakan salah satu jenis kemasan pangan yang banyak digunakan, untuk mencegah korosi. Logam biasanya dilapisi dengan pelapis epoksi resin seperti bisfenol A (BPA). BPA dapat mempengaruhi sistem endokrin dan dapat menyebabkan kerusakan pada berbagai jaringan serta organ. Penelitian ini bertujuan untuk mengetahui kandungan migrasi BPA pada kemasan kaleng sarden dan kornet serta paparannya pada penduduk Indonesia. Sampel yang digunakan adalah kemasan kaleng kosong untuk sarden dan kornet masing-masing 12 buah kemudian dianalisis menggunakan HPLC-UV Vis. Hasilnya menunjukkan bahwa konsetrasi migrasi BPA dalam kemasan kaleng sarden (menggunakan simulan etanol 20%) berkisar antara 0,005 – 0,05 mg/kg. Sedangkan dalam kemasan kaleng kornet (menggunakan simulan etanol 10%) sebesar 0,005 mg/kg. Rerata estimasi paparan perhari migrasi BPA dari konsumsi sarden dalam kaleng tertinggi terdapat pada usia 24-59 bulan yaitu 0,0546 µg/kgBB, sedangkan estimasi paparan perhari migrasi BPA dari konsumsi kornet dalam kaleng tertinggi terdapat pada usia anak 5-12 tahun yaitu sebesar 0,0066 µg/kgBB. Nilai risiko P95 untuk paparan migrasi BPA dari konsumsi sarden dalam kaleng pada seluruh kelompok usia sebesar 2,3883% sedangkan nilai risiko paparan dari konsumsi kornet dalam kaleng pada seluruh kelompok usia sebesar 0,3846%. Nilai risiko tersebut tidak melebihi asupan harian yang dapat ditoleransi sementara (tTDI), yang mengindikasikan bahwa paparan migrasi BPA melalui kemasan kaleng sarden dan kornet akibat mengkonsumsi sarden dan kornet tidak menimbulkan risiko bahaya terhadap kesehatan manusia di Indonesia.

Based on the results of several studies, it's questionable if freeze-thaw pretreatment can improve dried product qualities. To answer this question, a meta-analysis was conducted to determine the effect of freeze-thaw pretreatment on the quality of dried products. This research aimed to assess the impact of freeze-thaw pretreatment on the quality of dried plant-based foods. The data was sourced from the Scopus database, and the selection criteria were based on the PRISMA protocol. All meta-analysis calculations were performed using OpenMEE Software. The results revealed that freeze-thaw pretreatment significantly affected ΔE, TFC, and TPC. However, freeze-thaw pretreatment does not significantly affect shrinkage and hardness. Based on what the analysis subgroup found, the best freezing temperatures are -20 °C and -196 °C because both temperatures favorably impact TFC and hardness. Moreover, freeze-thaw pretreatment is applicable to I-C, NIR, and HA-MV drying.

Fruit rot disease is one of the important diseases that causes a high yield loss of snake fruit during storage. The alternative of postharvest process to maintain the quality of snake fruit is hot water treatment. This study aims to obtain a combination of soaking time and temperature that can control fruit rot disease of Pondoh snake fruit. The treatment consisted of 45, 50 and 55°C for 5 and 10 minutes and control. The results showed that hot water treatment had a significant effect on the snake fruit. Temperature of 50°C for 5 minutes is more effective in preventing the appearance of disease symptoms up to 10th days of storage, compared to controls which started to show symptoms on the 2nd day. Isolation of fungal pathogen from diseased control were found 4 fungi, i.e Thielaviopsis paradoxa, Aspegillus flavus, Fusarium sp. and Penicillium sp., while T. paradoxa and A. flavus are still found on treated diseased samples with hot water treatment. Hot water treatment did not affect the water content and total fruit acid but impacted to the weight loss and was able to maintain the hardness value and the panelist's preference level based on organoleptic tests.

Kelapa sawit (Elaeis guineensis, Jack) merupakan sumber pendapatan bagi jutaan keluarga petani, sumber devisa negara, penyedia lapangan kerja, serta sebagai pendorong tumbuh dan berkembangnya industri hilir berbasis kelapa sawit di Indonesia. Pelepah kelapa sawit merupakan limbah padat yang berasal dari perkebunan kelapa sawit. Kertas adalah bahan tipis yang dihasilkan dengan kompresi serat yang berasal dari pulp. Proses pembuatan pulp adalah dengan cara pemisahan senyawa lignin untuk mendapatkan serat selulosa dari kayu. Penelitian ini bertujuan memanfaatkan pelepah sawit untuk dimanfaatkan pada pembuatan kertas yang sesuai SNI. Tahapan penelitian ini adalah pencacahan, pencucian, perebusan, perendaman NaOH, perendaman H2O2, penghalusan, penambahan talcum, pencetakan dan pengeringan dengan oven pada suhu 75 0C, 80 0C, 85 0C. Sebanyak 64% panelis menyatakan bahwa kertas yang dihasilkan dengan suhu pengeringan 75 0C berwarna putih sedangkan pada suhu 80 0C sebayak 62% panelis yang menyatakan bahwa kertas yang dihasilkan berwarna putih dan pada 85 0C sebanyak 56% yang menyatakan kertas berwarna putih dan sesuai dengan SNI 4733.

Biofilm is an alternative packaging for food products in the form of thin layers made from natural materials that are safe to use and for consumption. One of the materials used in the manufacture of biofilms is starch. However, starch-based biofilms have a weakness, namely their low water resistance. The addition of green cayenne pepper leaf extract is thought to improve the physicochemical properties as well as the potential to become antimicrobial for biofilms. The purpose of this study was to determine the effect of the addition of green cayenne leaf extract on the physicochemical and antimicrobial properties of cassava starch biofilm. The green cayenne leaf extract formulations used in this study were F0 (control), F1 (1 ml), F2 (1.5 ml), F3 (2 ml), F4 (2.5 ml) and F5 (3 ml) with 3 repetitions each. The results of this study indicate that the addition of green cayenne leaf extract has a significant effect on thickness (0.17-0.26 mm), tensile strength (2.25-5.87 Mpa), elongation (44.9-81.9 % ), solubility (23.1-27.6 %), water vapor permeability (5.20-9.23 g/m.s.kPa), moisture content (11.3-11.8 %) and microbial inhibition on F5 results in higher values of F0 and F1.

Quality of melon indicated by size (fruit weight), appearance, and sweetness. In Indonesia, weight of high quality melon was 800 to 1,200 grams each. Mainly, the melon was cultivated in open fields during the dry season with several limitations of cultivation. To cope with those problems, melon was cultivated inside the greenhouse. However, there are several parameters influenced to melon quality inside the tropical greenhouse with hydroponic system. There were a few studies on the prediction model development of melon inside the greenhouse in a tropical area, Indonesia. The aim of this study was to develop an artificial neural networks (ANNs) model to predict the melon production inside the greenhouse (fruit weight) using several parameters such as the number of days to fruit formation, number of days to maturity, plant length, fruit width, fruit length, fruit cavity diameter, flesh diameter, branch number, fruit branch number, and leaf number. The result of this study was the ANN model with configurations of 10 input layers, 6 hidden layers, and 1 output layer with R2 was 0.93. This study concluded that there is a correlation between the input parameters with the weight of the melon.

One of the methods that can be used by Indonesian people in urban farming is the Aeroponic method of planting plants. The aeroponic method has a faster nutrient delivery speed than hydroponics and normal plant cultivation. The main objective of this study was to design an aeroponic monitoring and control system for Pakcoy (Brassica rapa. L) using the blynk application as an interface for remote control. The control system used is NodeMCU V3, DHT22 sensor, HC-SR04 ultrasonic sensor and TDS sensor. Plants in the system use a container box measuring 110 cm x 80 cm with 10 nozzles on the inside of the box attached to a ½ inch pipe, with 24 planting holes on the lid of the box with a spacing of 20 cm. The pump will automatically turn on when the temperature in the box is >25oC and will stop when the temperature is =24oC, or when the humidity is <80%. The results obtained during the 30 days of research showed that the average R2 value of the DHT22 sensor was 0.9864 and 0.9864, the HC-SR04 sensor was 0.996 and the TDS sensor was 0.9899. Observations on the growth of pakcoy plants obtained an average height of 13.3 cm for system plants and 13.4 cm for control plants. The average leaf width in system plants was 4.3 cm and 3.6 cm in control plants. the average number of leaves on system plants is 8 leaves and 9 leaves on control plants. The system plant weight was 5.493 gr and that of the control plant was 2.961 gr. The control system that has been made can work well and can be used in aeroponic cultivation of plants.

Penerapan konsep pemanfaatan limbah penggilingan padi sebagai sumber energi dapat mendukung peningkatan produktifitas energi terbarukan. Konsep eksergoekonomi dapat dijadikan sebagai salah satu satu langkah untuk melihat peluang sekam dapat dijadikan sebagai penambah energi di sistem penggilingan padi yang telah teritegerasi dengan gasifier. Specific Exergy Cost (SPECO) dijadikan sebagai metodenya, dimana metode tersebut menggabungkan analisis eksergi dan analisis ekonomi dengan menerapkan konsep biaya ke dalam sistem termal. Berdasarkan hasil analisisnya, gas produser mampu menjadi pengganti dari bahan bakar solar di sistem penggilingan padi berskala kecil. Jika dibandingkan dengan input tersebut sekam dan produk energi dari gasifier mampu menghasilkan eksergi masing-masing hampir 6 dan 4 kali lipat. Disamping itu, pemanfaatan gas produser juga dapat menekan biaya pengeluaran bahan bakar hingga mencapai 84,67%.

Horticultural crops have different classifications of land suitability for each plant. Therefore, accuracy is needed in the selection of crops for the land to be planted. This study aims to develop DSS for determining the type of horticultural crops adapted to agroecological characteristics. The methods used were Software Development Life Cycle (SDLC) with analysis for selecting suitable crops involving MOORA, BC ratio, NPV, and IRR. The validation process was carried out using land data from Panyingkiran District and Cikalongkulon District. The results show that the DSS made is able to provide recommendations that are in accordance with the state of agroecology on the actual land and plant categories, namely annual plants and perennial plants. The recommended horticultural crops also coincide with the plants cultivated by farmers in the respective areas.

Alat dan mesin pertanian (Alsintan) dibuat dengan tujuan untuk memudahkan kerja manusia dalam bidang pertanian. Misal, untuk memudahkan proses pengecilan dan mencapai keseragaman ukuran gula tebu dapat digunakan disk mill. Tujuan penelitian ini secara umum adalah melakukan uji teknis terhadap Disk Mill tipe FFC-15, dan secara khusus untuk mengetahui rendemen gula tebu dari hasil pengecilan ukuran menggunakan disk mill. Penelitian ini telah dilakukan di Laboratorium Manajemen dan Produksi Mesin Pertanian Departemen Teknik Pertanian dan Biosistem, Fakultas Teknologi Pertanian Universitas Andalas pada bulan September 2022. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial dengan lima kali ulangan. Hasil penelitian menunjukkan rata-rata nilai rendemen dan kapasitas kerja efektif pengecilan ukuran partikel gula tebu untuk seluruh perlakuan sebesar 88.13% dan 7.62 kg/jam dengan rata-rata kadar air sebelum dan sesudah pengecilan ukuran masing-masing 3.36% dan 2.04%. Nilai rendemen terbaik terdapat pada perlakuan ketiga (90.93%) dengan rata-rata putaran mesin sebesar 2,781.20 rpm. Selain itu, losses tertinggi terdapat pada perlakuan pertama dengan rata-rata nilai sebesar 15.37% pada kecepatan putaran mesin rata-rata 1,733.20 rpm.
