Nata is one of the organic food products that has a high fiber content. Nata is a product of fermentation by Acetobacter xylinum. The review that discusses the making of nata by analyzing the effect of the pH of the media and the duration of fermentation at the same time is still very limited. Thus, this review aims to discuss the effect of media pH and fermentation time on nata de coco bacilli. Paying attention to the factors that affect the growth of Acetobacter xylinum bacteria during the fermentation process needs to be done so that it can produce nata de coco with optimum thickness and weight and a chewy texture. These factors include the pH of the media and the length of fermentation. The ingredients for making nata de coco consist of coconut water, granulated sugar, ZA or Ammonium phosphate, and Acetobacter xylinum seeds. The method of implementing the activity which consists of counseling and practice of making nata de coco is able to increase the knowledge of residents, teachers, students (i) about nata de coco and coconut water which are potential natural plants (natural products), as well as skills (soft skills) in making nata de coco. The teachers, students(i) and residents admitted that they were greatly helped by this activity as a form of training that could be applied in their daily lives in entrepreneurship, even though it was a small scale.Keyword: nata de coco, media pH, fermentation time, education

Biodiesel can be made by utilizing used cooking oil through a chemical process, namely through a transesterification reaction, namely changing the oil (triglycerides) into fatty acid methyl esters. Washing must be done to remove the remaining impurities in biodiesel. The dry washing method is purification by utilizing the adsorption process to remove impurities in crude biodiesel. Bentonite is an alternative adsorbent that can be used as dry washing in the biodiesel refining process because it is cheaper, abundant in nature and has a layered structure with the ability to swell. The purpose of the study was to determine the ability of bentonite activated with acid as a dry washing agent in biodiesel purification. The research method used is the dry washing process method using bentonite adsorbents. The application of bentonite adsorbent as much as 6 grams with a contact time of 3 hours is the best operating condition to produce biodiesel with a pH of 6 and a clarity value of 96.7.

Shallots are an important food commodity for the needs of various Indonesian cuisines and other uses that are widely utilized. However, currently shallot farmers complain about post-harvest shallots that are easily damaged such as rotting, wrinkling, porous, root growth and fungal growth. To reduce this damage, preservation is needed. One alternative technology is Co-60 Gamma Ray Irradiation based on the principle of electromagnetic radiation that produces high-energy photons that cause ionization and excitation in the material it passes through. The nature of Gamma rays used in the preservation process has great penetrating power and does not cause temperature changes in the irradiated food. The purpose of this study was to determine the effect of Co-60 gamma ray irradiation on the optimization of the shelf life of post-harvest preservation of shallots with variations in control doses: low, medium and high, variations in temperature and quality parameters. The method of this research stage is: 1) Sample preparation. 2) Gamma Ray Irradiation of Co-60 with variation of control dose: low, medium and high 3) Analysis of temperature measurement and measurement of quality parameters (water content, weight loss, damage and hardness) against the irradiation dose. The results showed that gamma ray irradiation of Co-60 affected the length of shoots based on variation of dose and temperature, namely on day 1 and day 14 the combination of 650Gy treatment at 350C had the smallest shoot length, water content was relatively high, weight loss was relatively small, damage was relatively small and hardness was relatively high.

Mudahnya penyebaran virus korona mengharuskan kita menerapkan pola hidup bersih dan sehat sesuai protokol kesehatan yang ada melalui cuci tangan dan penyemprotan cairan kimia yang bisa membunuh virus dan kuman atau disinfeksi. Disinfeksi sendiri harus dilakukan dari lingkungan terkecil yaitu rumah dan dimulai dari diri sendiri. Penyemprotan cairan disinfektan tengah marak dilakukan di tengah pandemi global virus Covid-19. Tidak hanya oleh instansi resmi, warga juga berlomba-lomba melakukannya secara mandiri. (Budiman,2020). Sebagai alternatif pengganti disinfektan dari alkohol dan klorin, yaitu dengan menggunakan air rebusan daun sirih dan jeruk nipis yang merupakan bahan alami dan bisa kita temukan di pasar maupun di perkebunan. Daun sirih bisa menjadi alternatif di tengah kelangkaan bahan-bahan yang digunakan membuat cairan disinfektan. (Wisnu,2018). Pada penelitian ini menggunakan pendekatan penelitian yaitu Studi Pustaka (Library Research). Studi kepustakaan adalah pengumpulan data yang dilakukan dengan menelaah dan membandingkan buku, literatur, catatan, serta berbagai laporan yang berkaitan dengan masalah yang akan dipecahkan. Penggunaan daun sirih dan jeruk nipis untuk bahan alami pembuatan disinfektan terbukti efektif untuk menghambat penyebaran pathogen, membunuh pathogen, membasmi virus, kuman, jamur. Kandungan unsur-unsur senyawa dari kedua bahan alami ini berfungsi sebagai antiseptik alami terhadap beberapa pathogen, seperti Staphylococcus aureus., Bacillus sp., Escherichia coli, dan Salmonella Rafi.
