<p class="p0">Serabi Solo is a traditional food made from rice flour, coconut milk, sugar, salt, water and other ingridients. Serabi is round, flat and porous. Coconut milk was used to develop serabi's taste making it sweet and savory. However, rancidity can decrease quality of serabi during shelf life. Mold growth also affects food safety of this perishable food. Serabi Solo is developing as gift that has longer shelf life beside flavor and appearance variations. Concrete solutions to inhibit rancidity were matcha green tea because of poliphenol as an antioxidant. Matcha green tea addition and pasteurization improved Serabi Solo quality and inhibited rancidity. Based on previous research, matcha green tea 1% made Serabi shelf life longer (24,66 hours). Other solution was coconut milk pretreatment. According to previous research, lemon juice pH 3 was used in coconut milk with hurdle technique made Serabi Solo has shelf life longer (32 hours). Therefore, this activity was to introduce matcha green tea 1% and lemon juice pH 3 to extend shelf of Serabi Solo in SME Linco's Solo.</p><p class="p0"><strong>Bahasa Indonesia Abstrak</strong>: Kue serabi solo merupakan salah satu makanan tradisional yang terbuat dari tepung beras dan santan. Kue ini bulat, pipih dan berpori-pori. Penambahan santan saat memasak serabi membuat serabi terasa manis dan gurih. Namun, santan dalam serabi selain memberikan rasa gurih juga mudah mengalami kerusakan selama penyimpanan. Munculnya aroma dan rasa tengik yang tidak disukai menyebabkan penurunan kualitas dan daya simpan kue serabi. Selain itu, pertumbuhan kapang juga menjadi masalah keamanan pangan pada serabi. Padahal sebagai produk oleh-oleh, serabi diharapkan memiliki umur simpan lebih panjang selain variasi rasa dan tampilan yang menarik dan kekinian. Solusi aplikatif untuk menghambat ketengikan pada kue serabi solo adalah penggunaan matcha green tea karena mengandung polifenol sebagai antioksidan. Penambahan matcha green tea dan perlakuan pasteurisasi pada santan dapat memperbaiki mutu dan mampu menghambat proses ketengikan sehingga dapat memperpanjang umur simpan kue serabi. Hasil dari penelitian sebelumnya, pada uji ketengikan menunjukkan bahwa kue serabi dengan penambahan matcha green tea konsentrasi 1% memiliki umur simpan selama 24,66 jam. Selain penambahan, matcha green tea, upaya memperpanjang umur simpan serabi yaitu dengan mendesain pretreatment santan. Penelitian sebelumnya menggunakan jenis jeruk dan konsentrasi pH asam sitrat yang paling disukai konsumen dan pengaruh serta lama daya simpan serabi dengan pretreatment santan menggunakan teknik hurdle. Serabi yang paling disukai adalah serabi dengan formula pretreatment santan menggunakan air jeruk lemon dengan pH 3 yang memiliki umur simpan 32 jam. Oleh karena itu, pada kegiatan PkM ini mengaplikasikan matcha green tea 1% dan sari jeruk lemon dengan pH 3 untuk meningkatkan umur simpan serabi terhadap variabel ketengikan di UKM Lincos Solo. </p><div id="gtx-trans" style="position: absolute; left: 23px; top: 207.571px;"> </div>

“Kue kembang goyang” is a popular Indonesian traditional food made from rice flour. Millet flour with an amylose content equal to rice flour can be substituted for rice flour in the “kue kembang goyang” formulation. The research aimed to determine the amylose content of 3 varieties of foxtail millet flour (Setaria italica (L.) P. Beauv.) and to determine the best formula of “kue kembang goyang” in several ratios of foxtail millet flour:rice flour-based on crunchiness and oil absorption. The research was divided into two phases. Phase I, involved determining the amylose content of the three varieties of foxtail millet flour (erecta, compacta, glabra) and stage II involved determining the physical characteristics of “kue kembang goyang” in the ratio of foxtail millet flour:rice flour (0: 100, 20:80, 40:60, 60:40, 80:20) and concentration of coconut milk (20%, 30%, 40%). The result of phase I showed that the highest amylose content was found in foxtail millet flour of erecta variety (37.91 ± 0.51%). The phase II result showed that the ratio of foxtail millet flour:rice flour affected the texture and absorption of oil of “kue kembang goyang”. The higher the ratio of foxtail millet flour, the lower the count peaks, toughness, oil absorption, but the higher fracturability of “kue kembang goyang”. Increasing the concentration of coconut milk can increase count peaks, toughness, fracturability, and an oil absorption of “kue kembang goyang”. The best formula of “kue kembang goyang” was obtained in the ratio of foxtail millet flour:rice flour 60:40 and 30 % of coconut milk-based on the highest crunchiness and oil absorption resembled the control.

Studies were made of green plantain behavior when stored under various conditions to develop the best method of prolonging their shelf life without affecting their overall quality and processing characteristics. Freshly harvested green plantains start to ripen in about 7 days, reaching full ripeness 2 days later, when kept under room conditions at temperature of about 85° F. When stored in refrigerated chambers, plantains from the Guayamero and Maricongo cultivara remain green for 12 days, at which time signs of chilling damage begin to appear. However, the quality of plantains stored in these refrigerated chambers at 45° and 55° F. with relative humidities of 86 to 88 percent are definitely affected. At 45° F. a marked hardening of the fruits was observed and at 55° F., signs of false ripening appeared, impairing the quality of the produce. Shelf life of green plantains may be successfully prolonged, however, when thiobendazole-treated fruits are stored in sealed polyethylene bags containing an ethylene absorbent (about 200 g. of Purafil). TBZ was used in a 200-p.p.m. concentration to control mold growth. By using these combined techniques plantains were kept perfectly green for 25 days at room temperature (85° F.) and for 55 days under refrigeration (55° F.). This method had no detrimental effect on the stored fruit, as shown by the sensory evaluations of two processed products prepared from the stored green plantains at various intervals throughout the study. Tasters rated the samples as good or superior to similar products prepared from freshly harvested green fruit.

Food Safety sistem is a method that commonly use to guarantee the quality of food product in order to avoid hazard which can causing harm to the consumer. One of the well-known traditional food, Tempe, which is made from fermented soybean, has consumed by most of people in Indonesia. Tempe has a short shelf life. The aim of processing Tempe are to make the shelf life longer and also to diversify product of Tempe. One of the most popular product of Tempe is Tempe cracker. Parerejo village is well-known as one of the Tempe and Tempe cracker production base in East Java. Unfortunately, its production has not yet applied Food Safety Sistem. Some actions were needed in order to improve the knowledge of the Tempe and Tempe cracker producers about Food Safety Sistem. Firstly, questionnaires were distributed to the Tempe and Tempe Cracker producers in Parerejo village to determine the level of community understanding about Food Safety Sistem. After distributing the questionnaires, the next action was presenting of the definition, the aspects and the importance of implementation Food Safety Sistem in the production process of Tempe and Tempe cracker. Questionnaires showed that most of the producers of Tempe and Tempe crackers in Parerejo village realizes the importance of implementation Food Safety Sistem. In other hand, Food Safety Sistem has some obstacles to fully apply in the production process. The biggest challenge is the production facilities. Improving sanitation sistems such as sanitation of workers and equipment is one of the real efforts that can be done to improve the production sistem. Sortation of raw material also an effort to avoid physical hazard that can causing harm of the product. At least, awareness of the community about Food Safety Sistem have improved and committed to do some correction in order to avoid the hazard in production process.

The salt water mixes with fresh water and forms brackish water. The brackish water contains some quantity of salt, but not equal to sea water. Salinity determines the geographic distribution of the number of marshes found in estuary. Hence salinity is a very important environmental factor in estuary system. Sand is one major natural aggregate, required in construction industry mainly for the manufacture of concrete. The availability of good river sand is reduced due to salinity. The quality of sand available from estuarine regions is adversely affected due to this reason. It is the responsibility of engineers to check the quality of sand and its strength parameters before using it for any construction purpose. Presence of salt content in natural aggregates or manufactured aggregates is the cause for corrosion in steel. In this study the amount of salinity present in estuary sand was determined. Three different methods were used to determine the salinity in different seasonal variations. The sand sample collected nearer to the sea was found to be high in salinity in all methods.  It can be concluded that care should be taken before we use estuary sand as a construction material due to the presence of salinity.
