Every variety of apple has its particular physical characteristics, which are affected by different pre-harvest factors. Manual classification of these varieties by human labor has several weaknesses, such as the inconsistency, subjectivity, fatigue and different accuracy due to different level of experience of the inspector. This study was aimed to design and evaluate a simple computer-based vision system for recognizing and grading several varieties of apples based on their physical characteristics. Images of apples were taken and were used as training data with different algorithms to extract the particular characteristics of each variety, such as color and shape. The extracted Hue color channels and contour vector were recorded as the reference data and were used to recognize the similar characteristic of those images from the testing data group. The k-nearest neighbors algorithm was used to decide whether an apple belongs to a particular variety. The results show that the recognition rate based on color only was between 84–97% and it was between 5–77% it is based on the shape only. Rotating the image significantly increases the recognition rate (to be between 5 - 69% based on the shape only). Moreover, combining both color and shape characteristics significantly improves the recognition rate.

Eggplant (Solanum melongena L.) is a horticultural product widely distributed in Indonesia and is an easily damaged commodity during storage. Suitable storage conditions are needed to increase the eggplant's shelf-life. This study aims to determine the differences and the best conditions of packaging type, storage temperature, and shelf-life to maintain and improve the eggplant's quality. This research was conducted using a Nested Design with three replications. The analysis used includes weight loss, moisture content, ash content, pH, firmness level, protein content, fat content, and carbohydrates content. The results indicate that storage at cold temperatures (±8 °C) can inhibit metabolic processes, so there is a decrease in protein and carbohydrate content due to lower respiration processes than eggplant stored at room temperature (±27 °C). The type of polyethylene (PE) plastic packaging can reduce the potential for damage to eggplant during storage and increase the eggplant's shelf-life compared to brown kraft paper bag packaging and without packaging, which is characterized by better weight loss, protein, carbohydrates, and texture. Storage treatment for five days at cold temperatures (±8 °C) with PE plastic packaging was the best treatment in this study.

Bioethanol has been developed as an alternative biofuel. Elephant grass is one of the lignocelluloses that can be used as a source of bioethanol. The bioethanol fermentation process should be improved along with its economic competitiveness to promote its wider application. This study aims to investigate and to evaluate the best scheme of biethanol (standalone) and the combination of bioethanol and its by-products through technoeconomic analysis. The method used is collecting data from several previous studies and simulating it with SuperPro Designer. Data from flowsheeting simulation is used as economic simulation data using Microsoft Excel. The results of this study indicate that the processing of biogas and lignin waste as fuel and lignosulfonates can increase the economic value of the bioethanol production process. The best economic value is the bioethanol production process using biogas and lignin as fuel for a Biomass Power Plant which is called Pembangkit Listrik Tenaga Biomassa (PLTBm) with a Net Present Value (NPV) of IDR 364,358,976,036, Internal Rate of Return (IRR) 11.32%, Pay Back Period (PBP) 7.2 years, and Profitability Index (PI) 1.08

This study aims to determine the variations effect of black garlic concentration on the sauce's physical, chemical, and organoleptic characteristics. The experimental design used was a Completely Randomized Design with a single factor, the ratio of black garlic concentration to sauce paste. The experiment was performed with five treatments and three replications. The ratio of black garlic concentration to the sauce paste in this experiment was 5:95 (A1), 10:90 (A2), 15:85 (A3), 20:80 (A4), and 25:75 (A5). The results showed that the black garlic concentration significantly affected the sauce's physical and chemical characteristics (Total Dissolved Solids (TDS), color intensity, viscosity, antioxidant activity, and total polyphenols). The organoleptic test showed that black garlic concentration significantly affected panelists' preference for color, taste, viscosity, and overall parameters and did not significantly affect aroma preference. The best treatment was the sauce with a 15:85 (A3) concentration ratio of black garlic to sauce paste. The best treatment sauce's physical characteristics were 34.23±0.17 °Brix TDS, 1.35±0.12 color intensity, and 0.41±0.05 Poise viscosity, while the chemical characteristics were 22.75±0.38% antioxidant activity and 1.07±0.21 mg GAE/g total polyphenols. The organoleptic test of the best treatment sauce's results was 5.97 color preference, 5.30 aroma, 5.57 taste, 5.43 viscosity, and 5.23 overall preference.

Polyhydroxyalkanoates (PHAs) and exopolysaccharides (EPSs) are biopolymers bacteria under nutrient-limiting conditions. In this study, bacterial strains were isolated from hot springs. Soil samples were collected from Tatta Pani, Azad Kashmir, Pakistan. Bacterial strains AJ2 and AJ3 were selected due to their ability to produce PHAs and EPSs. Phylogenetic analysis showed that strain AJ2 was Micrococcus yunnanensis and AJ3 was Psychrobacter sp. Three carbon sources (glucose, glycerol, and molasses) were used for polymer production. The effect of high pH (8) and high temperature (55 °C) was checked on PHAs and EPSs production. The highest yield of PHAs was given by strain AJ3 (89.43%) with molasses. When grown at 55 °C for 24 hours, strain AJ3 showed the highest PHAs accumulation, 79% with glucose. At alkaline pH 8, strain AJ3 gave 34% PHAs with molasses. The highest EPSs production was observed for strain AJ3. AJ3 gave 70g/L of EPSs with both glucose and glycerol. The amplification of the phaC gene was done to confirm the genetic basis of PHAs production. FTIR analysis showed clear bands at 1722 cm-1 and 2925 cm-1 representing the carbonyl and alkyl groups of PHAs, respectively.

Sago grows in lowland and peat swamp regions that are relatively isolated due to limited basic infrastructures, including energy supply, especially electricity. These limitations constraining the development of sago starch production and industry. The sago starch production process generates by-products such as sago bark waste, pith waste, and wastewater which are potentially used as an energy source. This paper discusses a closed system model of an energy-independent sago starch production process from the utilization of by-products and wastewater. A mass balance model was developed to calculate the energy potency of by-products and waste to construct a closed system for the sago starch production process. The model's output showed that the by-product from processing 1,000 tons of sago stems per day with an optimal yield of 14% potentially generates 90,562 kWh of energy. This energy potency can meet the 26,070 kWh energy needed for sago starch production, making it possible to develop into a closed production system. Further research is needed to determine the site-specific aspects that affect energy sufficiency.

Peternakan ayam kini semakin banyak dijumpai di berbagai daerah di Indonesia. Baik dalam skala besar maupun skala rumahan. Namun, dalam kegiatan peternakan ayam tersebut muncul beberapa permasalahan yang dihadapi oleh masyarakat, khususnya peternak, yaitu ketika kotoran ternak bercampur dengan air dan urin dari ayam sehingga menimbulkan bau yang tidak sedap. Bau tak sedap ini seringkali merugikan petani dan lingkungan sekitar pertanian. Hal ini juga menyebabkan ketidaknyamanan masyarakat di sekitar area pertanian, yang sangat disayangkan. Padahal, jika pupuk kandang dikelola dengan baik, bisa dihasilkan produk lain yang, misalnya pupuk kandang. Penelitian ini bertujuan untuk mengetahui perbedaan screen mesh 10 dan 20 pada proses pengepresan kotoran hewan (pupuk kandang) khususnya ayam. Penelitian ini menggunakan kotoran ayam sebagai media. Metode yang digunakan dalam proses penelitian adalah dengan menguji dua mesh dengan media kotoran ayam kemudian dilakukan perbandingan yang meliputi konsumsi daya, tingkat penurunan kadar air, dan kapasitas produksi menggunakan alat pengukur kadar air untuk mengukur kadar air, tang meteran digunakan untuk mengukur arus yang mengalir pada kabel, dan tachometer digunakan untuk mengukur kecepatan putaran poros mesin pupuk kandang. Hasil dari pengujian ini meliputi konsumsi daya, tingkat pengurangan kadar air, dan kapasitas produksi. Hasil pengujian menunjukkan bahwa terdapat kelebihan dan kekurangan masing-masing mesh dengan pengujian yang telah dilakukan, mesh 20 adalah yang terbaik.

Saat ini, alat penyuplai air masih mengaplikasikan pompa elektrik dan dijumpai pada pompa hidrolik ram. Lalu, prinsip palu air diaplikasikan untuk menghasilkan tekanan. Tekanan air dihasilkan dari perubahan momentum massa fluida secara tiba-tiba. Peningkatan tekanan ini mampu meningkatkan meter kolom air. Metode penelitian dilakukan secara eksperimen. Perancangan instalasi pompa hidram menggunakan variasi diameter lubang katup 30, 31, 32 mm dan panjang langkah 10, 20, dan 30 mm. Hasil penelitian menunjukkan head water hammer ditingkatkan pada langkah lebih panjang. Performa pompa terbaik dihasilkan pada panjang langkah 30 mm dan mengoptimalkan head water hammer 24 m. Di sisi lain, head water hammer menajdi berkurang pada discharge valve yang lebih besar.

Salah satu metode perbaikan pipa tanpa menghentikan aliran fluida yang mengalir adalah sleeve repair dengan pengelasan in-service. Risiko hydrogen cracking pada pengelasan in-service dapat dihindari dengan mengontrol kekerasan pada HAZ maksimum 350 VHN. Pada penelitian ini, dilakukan pengelasan melingkar pada konfigurasi sleeve tipe B berdiameter 4" dan tebal 6 mm menggunakan metode pengelasan FCAW (semi otomatis) dengan aliran air sebesar 5 liter/menit. Alat yang digunakan untuk pengelasan adalah robot memutar sederhana pada pipa dan mesin las Daiden MIGi 200 dengan elektroda E71T-11 berdiameter 0,8 mm. Beberapa parameter pengelasan seperti arus, voltase, dan kecepatan feed elektroda diatur konstan berturut-turut sebesar 120 ampere, 20 volt, dan 7,5 meter/menit. Sementara kecepatan pengelasan divariasikan mulai dari tercepat 10 mm/detik, 6 mm/detik, hingga paling lambat 1 mm/detik. Kekerasan pada las sendiri teramati lebih tinggi dari HAZ. Sementara itu, kekerasan pada CGHAZ diamati lebih tinggi daripada FGHAZ. Kekerasan HAZ cenderung meningkat seiring bertambahnya kecepatan pengelasan. Nilai kekerasan maksimum untuk kecepatan 1, 6, dan 10 mm/s (atau heat input 4.800, 400, dan 240 J/mm) berturut-turut sebesar 250, 351, dan 465 VHN. Menimbang batasan kekerasan yang diacu, potensi terjadinya hydrogen cracking dapat diamati pada kecepatan pengelasan 6 mm/s (heat input 400 J/mm) sehingga direkomendasikan agar pengelasan dilakukan dengan kecepatan di bawah itu.
