Abstract

The study was conducted at two locations, namely the headwaters and mid stream part Ciliwung. A teach location made six transects with 45m length of each transect. Each transect made 5 sample plots measuring 1x1m with the distance between sample plots is 10m.  Then be identified, then calculated FR, KR, INP and Diversity Index Type. Based on the research results, There are 23 species of plants preventing erosion which is included in the 14 family. Ciliwung headwaters part  there are 19 species of plants preventing erosion of the 12 family, with a percentage of 57,5% and the highest Importance Value Index was Panicum maximum of 41.83%. Ciliwung midstream part there are 15 species of plants preventing erosion of the 9 tribes, with a percentage  45,4%  and  the highest Importance Value Index was  Pennisetum purpureum of 44.16%. Plant species diversity index prevention of erosion in watersheds (DAS) Ciliwung low with values ranging between 0,90-0,95. Key words: erosion control plants, watershed (DAS), Ciliwung

Abstract

Heavy metals in waters are a threat to living things both biota that are in these waters, as well as on plants and humans that depend on these water sources. Water quality improvement can be done by utilizing local gravestone (Pilsbryoconcha exilis) as a natural filter. In this study consisted of four treatments and three replications. The amount of gravestone weights of 200 grams, 300 grams and 400 grams acts as a treatment that will later be seen its effect on water containing arsenic metal. The results of this study indicate that local gravestone can reduce arsenic levels in waters with a treatment weight of 400 grams showed the best results with the final result arsenic level of 0.0101 ppm and the highest daily growth rate is 200 grams of weight treatment with a market value of 4.40%.

Abstract

Plants, like other living things, need a combination of nutrients to live, grow and reproduce. Nutrients in plants can also be divided into two, namely mobile nutrients and immobile nutrients (non-moving nutrients). The condition of plants that are deficient or lacking in nutrients will experience growth disturbances and affect the yield of leaves or fruit. Leaf color can be a characteristic of plants under normal conditions or experiencing nutrient deficiencies. Deficiency of nutrients in plants will affect leaf shape, fruit production and plant age which results in stunted growth and rapid death of plants, in fruit production there will be loss of flowers or ovaries so that production will decrease. So far, plant maintenance has been done manually. Each plant is seen for later analysis of the results and it takes time to identify nutrient deficiencies. The aim of the study was to identify nutrient deficiencies in image-based chili plants based on the characteristics of the Red, Green, Blue (RGB) color and texture analysis using the Support Vector Model (SVM). The benefit of the research is to make machine learning-based applications to identify nutrient deficiencies which are divided into four classes, namely nitrogen (N) and phosphorus (P) deficiencies, P and potassium (K) deficiencies, N and K deficiencies, and chili leaves with normal class. .There are 120 plant data with an accuracy of 84.4%.

Abstract

Desa Cisalada merupakan salah satu Desa di wilayah Kecamatan Cigombong, Kabupaten Bogor. Mata pencaharian di desa tersebut didominasi oleh buruh, petani, pedagang, serta buruh rumah tangga, dengan tingkat pendidikan didominasi oleh jenjang SD dan SMP. Di desa tersebut pemukimannya padat dengan pekarangan yang sempit, selain itu terdapat beberapa lahan yang tidak produktif. Tujuan dari kegiatan pengabdian ini adalah memberikan pengetahuan dan keterampilan masyarakat dalam memanfaatkan lahan pekarangan yang sempit dan lahan non produktif melalui hidroponik. berupa penyuluhan dan pelatihan kepada masyarakat desa tersebut Program dilaksanakan dengan melakukan pembinaan, pelatihan, dan pendampingan tentang budidaya hidroponik. Hasil kegiatan ini adalah bertambahnya wawasan masyarakat non produktif mengenai pemanfaatan lahan non produktif dengan sistem hidroponik. Keterampilan masyarakat meningkat, dengan dapat melakukan penanaman, pemeliharaan dan penanganan pasca panen sayuran menggunakan metode hidroponik. Masyarakat dapat menyediakan sayuran untuk kebutuhannya sendiri.

Abstract

Upaya perlindungan terhadap burung jalak Bali Leucopsar rothschildi di Indonesia dilakukan antara lain melalui penangkaran. Keberhasilan upaya penangkaran dapat dilihat dari meningkatnya populasi satwa yang ditangkarkan. Penelitian ini dilakukan untuk menganalisis sumber protein yang menghasilkan laju pertumbuhan optimal anak jalak Bali di Penangkaran Kere Ayem Bird Farm. Penelitian menggunakan Rancangan Acak Lengkap dengan tiga perlakuan sumber protein, dan tiga ulangan. Pakan diberikan pada anak burung berumur satu minggu dengan cara diloloh (hands feeding), selama enam minggu. Pakan yang diberikan adalah bubur pur yang ditambahkan sumber protein berbeda, yaitu ulat Hongkong, ulat Jerman, dan jangkrik. Variabel yang diukur yaitu pertambahan bobot tubuh, panjang tubuh, panjang kepala, panjang sayap, panjang ekor, panjang kaki, panjang paruh, dan pertumbuhan bulu burung. Pemberian jangkrik dalam pakan menghasilkan laju pertumbuhan tertinggi anak jalak Bali, dibandingkan ulat Hongkong, dan ulat Jerman. Enam dari tujuh variabel pertumbuhan, menunjukkan beda nyata akibat perlakuan, sedangkan pertambahan panjang paruh tidak berbeda nyata. Pertambahan ukuran-ukuran tubuh anak jalak Bali yang tertinggi terlihat pada minggu ke dua perlakuan. Pemberian jangkrik sebagai sumber protein hewani lebih disukai anak jalak Bali, dan meningkatkan pertambahan ukuran-ukuran tubuh, serta pertumbuhan bulu.

Abstract

Lahan basah merupakan ekosistem perairan darat yang berperan penting memsok air bagi kebutuhan manusia. Penurunan kualitas perairan sungai akan berdampak terhadap keragaman jenis fauna avertebrata di ekosistem tersebut. Daerah Aliran Sungai (DAS) Cisadane merupakan aliran sungai besar, dengan daerah tangkapan air seluas 1.100 km2. Salah satu cara menilai kualitas air sungai secara biologi adalah melalui analisis makroavertebrata, karena kepekaannya terhadap bahan pencemar. Penelitian ini ditujukan untuk konservasi DAS Cisadane melalui analisis keragaman dan kelimpahan makroavertebrata. Pengambilan data dilakukan pada empat stasiun pengamatan, yaitu area Maseng (stasiun I), Pamoyanan Sari (stasiun II), Cibalagung (stasiun III), dan Bubulak (stasiun IV). Penelitian ini berhasil mengidentifikasi 21 spesies avertebrata, dengan tiga spesies paling melimpah, yaitu Pantala flavescenes (capung ciwet), Parathelphusa convexa (ketam/yuyu sawah), dan Lumbricina (cacing tanah). Tingkat keragaman spesies avertebrata secara keseluruhan termasuk dalam kategori keragaman sedang (indeks H’= 1,93). Tingkat keragaman spesies, dan kelimpahan spesies avertebrata ke arah hilir DAS Cisadane semakin menurun, berdasarkan kriteria indeks keragaman Shannon-Wienner, dan kelimpahan relatif spesies. Kualitas air sungai Cisadane terindikasi tercemar ringan-sedang di stasiun I, II, III, dan tercemar sedang-berat di stasiun IV.
