Fertilizer is a source of nutrients needed by plants, as well as sea grapes. Bat Manure found in the caves of Bolok Village have not been properly utilized and have the potential to be used as a basic ingredient in fertilizer. However, the bat manure must be processed first through composting because plants cannot absorb nutrients from organic matter that is still raw, regardless of its form and origin. The purpose of this community service activity is to provide community knowledge and skills regarding the manufacture of Bat Manure Liquid Organic Fertilizer starting from the preparation of materials, packaging to labeling. The method used in this service activity is a combination of lectures, discussions and practices. Community service activities were responded very well by the local community, this was shown by the active participation of the residents in all stages of the training so that they could run smoothly. It is hoped that in the future this fertilizer can become an alternative product so that it can overcome fertilizer scarcity and reduce production costs and can become an additional livelihood for the people of Bolok Village.

Kotoran kelelawar mengandung banyak unsur hara yang tinggi (N, P, K, Ca, Mg, S), namun di sisi lain hasil buangan kelelawar ini mengandung C/N rasio yang rendah sehingga perlu dilakukan suatu proses untuk meningkatkan C/N rasio yang pada akhirnya dapat dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk mengetahui kadar nitrat dan fosfat pada pupuk guano serta pemanfaatannya untuk pertumbuhan anggur laut (Caulerpa racemose). Penelitian ini dilaksanakan pada bulan Oktober sampai November 2021 bertempat di Teaching Factory Budidaya, Politeknik Kelautan dan Perikanan Kupang, Nusa Tenggara Timur. Pembuatan pupuk guano dilakukan menggunakan kotoran kelelawar, EM4, gula merah, terasi, dan air tawar sebagai pelarut yang difermentasikan selama 12 hari dan dilakukan pengujian sampel setiap tiga hari sekali. Hasil penelitian menunjukkan bahwa kotoran kelelawar secara alami mengandung kadar fosfat dan nitrat berturut-turut sebesar 1,030 mg/L dan 2,308 mg/L. Kadar fosfat dan nitrat selama 12 hari fermentasi mengalami penurunan dan kenaikan dan diperoleh hasil kadar fosfat dan nitrat pada hari ke-12 sebesar 1,302 mg/L dan 2,296 mg/L. Peningkatan dan penurunan kadar fosfat dan nitrat berkaitan dengan aktivitas mikroorganisme yang terdapat di dalam EM4. Hasil penelitian menunjukkan bahwa pupuk guano mengandung kadar fosfat dan nitrat yang dapat dimanfaatkan sebagai sumber nutrisi bagi tanaman dan terbukti dapat meningkatkan pertumbuhan anggur laut (C. racemose) dengan menaikkan bobot anggur laut dan panjang serta jumlah ramuli. Pupuk guano yang diperoleh dapat dijadikan alternatif pengganti pupuk organik yang harganya relatif mahal di Kota Kupang.

ABSTRAK Anggur laut (Caulerpa sp.) merupakan salah satu jenis rumput laut yang memiliki nilai ekonomis tinggi yaitu dapat dimanfaatkan sebagai bahan makanan, pangan fungsional, dan obat.Sebagian kecil masyarakat wilayah Nusa Tenggara Timur telah mengenal anggur laut, namun pemanfaatannya masih sangat terbatas sebagai bahan makanan segar saja atau disebut dengan lawar. Anggur laut tersebut diperoleh dari alam sehingga ketersediaannya sangat tergantung dari alam dan kondisi musim. Budidaya merupakan cara yang dapat dilakukan untuk memastikan ketersediaan dan jumlah anggur laut sehingga dapat dimanfaatkan oleh masyarakat secara berkelanjutan. Tujuan kegiatan ini adalah memberikan sosialisasi tentang budidaya serta potensi anggur laut, dan memberikan pelatihan tentang budidaya anggur laut bagi masyarakat Desa Bolok.Kegiatan pengabdian kepada masyarakat ini bermitra dengan Kelompok Tani Rumput Laut â€œUT LATUâ€ yang beralamat di Dusun III, Desa Bolok, Kupang Barat, NTT.Metode pelaksanaan kegiatan dilakukan dua tahap. Tahap pertama adalah sosialisasi tentang budidaya anggur laut, manfaat anggur laut, produk olahan anggur laut dan tahap kedua adalah pelatihandengan tahapan persiapan alat dan bahan, penimbangan bibit anggur laut, penanaman dalam media tanam berupa PE, penambahan pupuk Guano, pemasukan media tanam ke dalam kontainer box, monitoring pertumbuhan, panen, dan pengawetan sederhana anggur laut.Pada saat panen diperoleh bobot anggur laut berkisar antara 680 â€“ 1210 g dari bobot awal 400 g selama pemeliharaan 30 hari, pertumbuhan relatif diperoleh nilai 70 â€“ 203%. Setelah kegiatan ini dilaksanakan, masyarakat mulai menyadari akanmanfaat anggur laut, dan dapat ditumbuhkan pada kontainer box yang diletakkan di pekarangan rumah sehingga dapat menjadi alternatif kegiatan budidaya oleh masyarakat.

Aquaculture is a food production sector that is developing quite rapidly in the world with a projection that production will double in the next 15-20 years. However, to run a cultivation system, you must have a large area of â€‹â€‹land and large capital. The Covid-19 pandemic has had an impact on all aspects of people's lives. One of the aspects most affected by the pandemic is the economy, namely the occurrence of mass layoffs. Therefore, it is necessary to make alternative efforts that can help increase people's income during a pandemic, with a low risk of failure, and easy to implement as a side business during a pandemic. Budikdamber or also known as fish farming in buckets, can be an alternative business that can be done to maintain food security and increase income during a pandemic. Budikdamber is a form of fish farming that is inexpensive and easy to implement. The Budikdamber extension activity is one way to educate the community around Bolok Village, West Kupang, NTT. This PkM program was carried out with the output of the Budikdamber extension activity on November 9, 2020, attended by 56 participants from Bolok Village, West Kupang District, Kab. Kupang. The output of this program is that the people of Bolok Village are more educated about the easy and inexpensive practice of catfish farming in order to maintain independent food security in the midst of the Covid-19 pandemic and at the same time become an alternative solution for people's income, because they do not use large land and can take advantage of the yard. .
