Abstract

The process of making tofu includes several steps, namely the process of soaking soybeans, washing soybeans, milling soybeans, boiling or cooking, filtering, settling and adding vinegar. The purpose of this study it was to obtain a Petri Net model of the tofu making process and perform simulations with signed Petri Nets. Simulations are carried out to determine the dynamics that occur during the process of making tofu. The data used is by observation in a household-scale tofu and tempeh processing industry in Tarakan City. The Petri Net model obtained consists of six transitions and ten places. Assuming that every enable transition will always be fired in every state, there are sixteen possible states that can be achieved in the Petri Net simulation.

Abstract

Several agricultural activities around the world emphasize the need to develop technology for cultivating plants in greenhouses that consumes low costs energy. Rainwater harvesting in areas with high rainfall is an alternative source of irrigation water for greenhouse plants. Rainwater harvesting results can be used in greenhouses as a source of fertigation water and microclimate control. Plants require an adequate amount of water on a continuous basis, and this is one of the factors that contribute to the success of greenhouse plant cultivation. The purpose of this article is to increase understanding of rainwater harvesting for irrigation systems and microclimate control in greenhouses. The results of rainwater harvesting from the rooftop greenhouse can meet 61.49-69% of the greenhouse's irrigation water needs. Microclimate reference, substrate moisture content, soil/planting media moisture content, and phyto-sensing can all be used to guide greenhouse irrigation. Rainwater harvested meets irrigation water quality criteria and can save money on irrigation costs. Furthermore, rainwater harvesting results can be used as a source of raw water for fertigation systems and microclimate control in greenhouses. Rainwater harvesting for greenhouse microclimate control can reduce temperatures by 1.3-3.6 °C and is less expensive than fan cooling systems.

Abstract

Abstrak. Pengeringan merupakan faktor penting dari pengolahan kopi, tanpa pengeringan yang tepat baik itu pengeringan mekanis maupun secara tradisional kualitas biji kopi tidak akan memenuhi standar yang disyaratkan. Proses pengeringan yang baik tidak hanya berpengaruh terhadap sifat fisik biji kopi seperti tingkat kadar air, namun juga meningkatkan citarasa dan aroma dari biji kopi tersebut. Karakteristik terbaik yang diperoleh dari biji kopi setelah proses pengeringan akan menentukan kualitas produk kopi di pasaran. penelitian ini bertujuan mengetahui pengaruh metode pengeringan terhadap penurunan kadar air dan sifat organoleptik biji kopi arabika dan robusta sehingga didapatkan metode terbaik dalam pengolahan kopi. 50 kg biji kopi Arabica dan robusta dikeringkan di bawah sinar matahari dengan menggunakan alas terpal, sedangkan 50 kg sisanya dikeringkan menggunakan mesin pengering biji-bijian tipe batch. Uji organoleptik (rasa dan aroma) menggunakan metode uji Hedonik dan diolah dengan analisis sidik ragam. Pengeringan biji kopi secara mekanis menunjukkan penurunan kadar air yang lebih cepat (17jam) daripada pengeringan secara tradisional (23 jam). Hasil pengujian rasa dan aroma menunjukkan biji kopi Arabica yang dikeringkan menggunakan mesin pengering mekanis lebih disukai panelis dengan nilai uji hedonik tertinggi (67 dan 63 poin). The Effect of Drying Methods on the Characteristics and Organoleptics of Arabica Coffee Beans (Coffeae Arabica) and Robusta Coffee Beans (Coffeae Cannephora) Abstract. Drying is an important factor in coffee processing, without proper drying, both mechanical drying and traditionally the quality of coffee beans will not meet the required standards. A good drying process not only affects the physical properties of coffee beans such as the level of water content, but also increases the flavor and aroma of the coffee beans. The best characteristics obtained from coffee beans after the drying process will determine the quality of coffee products on the market. This study aims to determine the effect of drying method on decreasing water content and organoleptic properties of arabica and robusta coffee beans so that the best method in coffee processing is obtained. 50 kg of Arabica and robusta coffee beans are dried under the sun by using terpal, while the remaining 50 kg is dried using a batch-type grain drying machine. Organoleptic test (taste and aroma) using Hedonic test method and processed by analysis of variance. Mechanical drying of coffee beans shows a decrease in water content faster (17 hours) than traditional drying (23 hours). The taste and aroma test results showed Arabica coffee beans dried using a mechanical drying machine were preferred by panelists with the highest hedonic test values (67 and 63 points).

Abstract

Abstrak                                                                                 Sonneratia alba memiliki buah yang cukup besar dan memiliki rasa masam. Masyarakat sekitar Desa Sengkong biasa memanfaatkannya sebagai bahan tambahan masak ikan kuning. Ketersediaan buah yang berlimpah di desa ini mendorong tim PKM untuk memanfaatkan buah tersebut untuk diolah menjadi minuman yang mengandung antioksidan. Buah bakau atau prepat/pedada memiliki kandungan flavonoid yang baik untuk penangkal radikal bebas didalam tubuh, selain itu kandungan ini juga bermanfaat untuk membunuh bakteri yang ada pada tubuh. Setelah masyarakat diberikan informasi tentang manfaat dari buah prepat, maka tumbuh kesadaran masyarakat Desa Sengkong untuk mulai memanfaatkan dalam membuat produk turunannya. Mulai dari sirup, sabun, dodol dan lain sebagainya. Produk sekunder ini akan memudahkan masyarakat mengkonsumsinya dalam varian rasa dan tekstur. Selain itu juga bisa menambah pendapatan rumah tangga karena telah lahir UMKM baru dalam bidang olah produk pertanian. Kata Kunci: buah; mangrove; sirup; sonneratia alba; antioksidan AbstractSonneratia alba has a fairly large fruit and a sour taste. People around Sengkong village usually use it as an additional ingredient for cooking yellow fish. The abundant availability of fruit in this village encouraged the PKM team to use the fruit to be processed into a drink that contains antioxidants. Mangrove fruit, or prepat/pedada, contains flavonoids that are good for counteracting free radicals in the body. Besides that, this content is also useful for killing bacteria in the body. After the community was given information about the benefits of prepat fruit, the awareness of the people of Sengkong village grew, and they started utilizing it in making derivative products. Starting with syrup, soap, dodol, and so on. These secondary products will make it easier for people to consume them in a variety of flavors and textures. In addition, it can also increase household income because new UMKM have been born in the field of processing agricultural products. Keywords: fruit; mangrove; syrup; sonneratia alba; antioxidant

Abstract

Malinau Robusta coffee demonstrates untapped potential within the specialty coffee market. This study aims to evaluate the quality of Malinau coffee comprehensively and benchmark it against prominent specialty coffees such as Gayo, Toraja, and Kintamani. A descriptive quantitative method was employed to analyze critical parameters including caffeine content, moisture level, defect value, impurity level, grain size, and flavor profile. Coffee samples were gained from nine coffee-producing villages in Malinau Regency, involving 28 farmers covering 190 ha of coffee plantations. The results identified distinct strengths of Malinau coffee, notably its low moisture level (10.2%) and high caffeine content (1.94%) among the samples, offering a strong and intense flavor profile including chocolatey, a bitter aftertaste, and fruity undertones. Challenges for Malinau coffee includes high defect value (65.7/300 g) and impurity level (0.6%), which undermine its marketability in premium segments. To bring Malinau coffee up to par with other established specialty coffees, improvements in post harvest handling are needed, particularly sorting, quality control and consistent processes methods. By adopting innovative cultivation and processing, Malinau coffee holds strong potential as a competitor of specialty coffee, both for domestic and global markets while highlighting its unique regional identity. Keywords: Malinau coffee, North Kalimantan, Quality improvement, Robusta, Specialty coffee.
