BAKTERI PENGHASIL AMILASE YANG DIISOLASI DARI EKOENZIM LIMBAH BUAH-BUAHAN
Get PDFMany of potential enzymes can be found in the ecoenzyme, one of them is amylase. Amylase is an enzyme that is able to hydrolize the glycoside bonds of starch or starch into dextrin, glucose and maltose which is widely used in various industries such as beverages. This study aims to isolate the ecoenzyme bacteria and test their ability to produce amylase. Isolation of ecoenzyme bacteria was carried out using serial dilution methods 10-1, 10-3, 10-5. A total of 0.1 ml of each dilution series was pipetted and spread on the Nutrient agar (NA) medium. The bacterial isolates that grew were then purified and identified by morphological observation, Gram staining and their enzymatic activity was tested using Starch Agar (SA) media qualitatively. The results of this study showed there were 39 bacterial isolates from ecoenzyme with different morphological characteristics. The amylase activity test were found that 34 isolates had a positive activity to hydrolize the starch in the SA media which was indicated by the formation of a clear zone around the bacterial colonies. Each bacterial isolate had a different hydrolysis index value, which ranged from 9.45 to 23.65. The highest clear zone diameter index value from starch hydrolysis was EJM 15 isolate.

BANK SAYUR ORGANIK ALTERNATIF MENINGKATKAN KETAHANAN PANGAN RUMAH TANGGA DI DESA SETIAWARGI
Get PDFThe fact that the village is the recipient of conditional social assistance for the poorest families in Tamansari District, Tasikmalaya City in 2019 is a component of great concern in Setiawargi Village. Food security, particularly during the current pandemic, is one of the issues associated with the community in the village. There is concern that this will further worsen the household food security situation, particularly for sustainable farming households. In Depok, Setiawargi Village, the alternative offered by external parties, namely the Siliwangi University Community Service Team through the Food Security Scheme, is to assist in the procurement of organic vegetable banks to target farming group partners and women's farming groups. The implementation activities to be carried out include: 1) observation of the community's initial needs; 2) preparation of seeds and post-observation equipment; (3) Home yard optimization counseling; (4) Introduction to organic vegetable banks; (5) Organic vegetable packaging, design, and marketing training; and (6) Organic vegetable planting assistance. The results of this activity suggest that the local community is passionate about the concept of an organic vegetable bank. The issue, however, is that the use of organic fertilizers has not been maximized so far because of the long-term results obtained. Other external parties, such as farm extension workers who work in synergy with the community service team, must continue to assist the local community to experience the minimal benefits of an organic vegetable bank for the welfare of the family, hoping to meet the needs of other communities in the future.Komponen yang menjadi perhatian besar di Desa Setiawargi adalah desa tersebut merupakan penerima bantuan sosial bersyarat keluarga miskin terbanyak se-Kecamatan Tamansari, Kota Tasikmalaya pada tahun 2019. Salah satu permasalahan yang dihadapi masyarakat di desa tersebut terkait dengan ketahanan pangan terlebih di masa pandemi sekarang ini. Hal ini dikhawatirkan semakin memperparah kondisi ketahanan pangan keluarga khususnya rumah tangga tani secara berkelanjutan. Alternatif yang ditawarkan pihak eksternal, yakni Tim Pengabdian Pada Masyarakat Universitas Siliwangi melalui skema Ketahanan Pangan adalah pendampingan pengadaan bank sayur organik pada mitra sasaran kelompok tani dan kelompok wanita tani di Kampung Depok, Desa Setiawargi. Kegiatan pelaksanaan yang dilakukan meliputi: 1) Observasi kebutuhan awal masyarakat; 2) Persiapan benih dan peralatan pasca observasi; 3) Penyuluhan optimalisasi lahan pekarangan; 4) Pengenalan bank sayur organik; 5) Pelatihan pengemasan, desain, dan pemasaran sayur organik; dan 6) Pendampingan penanaman sayur organik. Hasil kegiatan ini menunjukkan bahwa masyarakat setempat antusias dengan adanya ide bank sayur organik. Namun permasalahan yang timbul adalah selama ini penggunaan pupuk organik kurang dimaksimalkan karena hasilnya yang memakan waktu lama. Dibutuhkan peran serta pihak eksternal lainnya, seperti penyuluh pertanian yang bersinergi dengan tim pengabdian untuk terus mendampingi masyarakat setempat agar merasakan manfaat bank sayur organik minimalnya untuk kesejahteraan keluarga, dengan harapan kedepannya memenuhi kebutuhan masyarakat lainnya
