Abstract

Penelitian ini bertujuan untuk mengetahui kualitas terbaik antara tiga jenis rumput yaitu rumput Pakchong, rumput Zanzibar, dan rumput Biograss Agrinak pada interval pemotongan yang berbeda-beda yakni pada umur pemotongan 50 hari (U1), 60 hari (U2), dan 70 hari (U3). Metode yang digunakan dalam penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola Faktorial dengan dua faktor. Percobaan dilakukan dengan ulangan 3 kali sehingga didapatkan 9 kombinasi. Adapun variabel pada penelitian ini yaitu Bulk dencity, Daya Serap (Water Regain capacity), Daya Larut (Water Sulobility), Energi Bruto (Gross Energy), Total Degestible Nutrien (TDN). Rumput Pakchong berbeda nyata (P<0,05) paling tinggi pada bulk dencity, daya larut air (Water solubility), energi bruto (Gross energy), dan TDN (Total Digestible Nutrient) dibandingkan rumput Zanzibar dan rumput Biograss Agrinak. Umur pemotongan berpengaruh nyata (P<0,05) terhadap kualitas fisik (Bulk density) dan berpengaruh sangat nyata (P<0,01) terhadap Energi Bruto (Gross energy), pada pemotongan umur 60 hari paling tinggi. Interaksi antara jenis rumput dan umur pemotongan hanya terjadi pada variabel pengamatan daya larut air (Water solubility) tertinggi pada kombinasi perlakuan rumput Pakchong dengan umur pemotongan 70 hari (R1U3), dan variabel TDN tertinggi pada kombinasi perlakuan rumput Zanzibar dengan umur pemotongan 50 hari (R2U1).

Abstract

Kegiatan PKM ini dilaksanakan pada Kelompok Tani Ternak “Wana Sari Merta” di Desa Pancasari, Kecamatan Sukasada-Kabupaten Buleleng, Provinsi Bali dengan judul ”PKM Pemanfaatan Kotoran Kelinci Pada Kelompok Tani Ternak Di Kawasan Wisata Desa Pancasari-Kecamatan Sukasada, Kabupaten Buleleng Provinsi Bali”. Sampai saat ini di Desa Pancasari yang berada disekitar lokasi wisata Danau Buyan dan Danau Tamblingan masyarakatnya dalam budidaya tanaman yang banyak dikembangkan tanaman cabai, tomat, sawi, kentang, brokoli, selada, wortel, stroberi dan jenis lainnya dan masih banyak menggunakan pupuk organik yang berasal dari kotoran ayam yang mudah didapat dalam jumlah besar dan dapat memenuhi kebutuhan luasan tanam yang cukup luas. Kesempatan ini sebenarnya dapat dimanfaatkan oleh masyarakat petani ternak khususnya kelinci sebagai peluang untuk mensuplai pupuk organik dari limbah kelinci baik padat maupun cair. Sampai saat ini permasalahan yang dihadapi mitra adalah kotoran padat dan cair belum diolah secara optimal dan memproses /memproduksi pupuk organik dari kotoran tersebut belum secara intensif/hanya sewaktu-waktu sesuai permintaan, produk belum dikemas dengan baik dan belum ada label sehingga dalam proses pemasaran belum dapat dikenal secara luas asal produsennya yang menjadi kendala bagi kelompok mitra, aspek manajemen dan pemasaran produk serta faktor penunjang lainnya masih perlu ditingkatkan. Solusi yang sudah diberikan pada kelompok mitra adalah transfer teknologi budidaya kelinci penyiapan pakan fermentasi, teknologi pengolahan kotoran kelinci, uji mutu produk pada laboratorium, kemasan dan pelabelan, manajemen usaha, pemasaran, temu usaha/mitra, serta bantuan alat dan bahan. Tujuan kegiatan PKM ini bagi mitra adalah: adanya peningkatan pengetahuan dan keterampilan mitra dalam budidaya kelinci serta memanfaatkan limbah padat dan cair kelinci sebagai pupuk organik dalam mensubstitusi penggunaan pupuk anorganik yang ada di wilayah mitra. Selain itu, dapat menjadi alternatif bahwa limbah padat dan cair kelinci bagi masyarakat disekitar mitra dapat dipakai sebagai pupuk organik dalam pemupukan tanaman yang dibudidayakan selain pupuk-pupuk organik dari ayam yang telah digunakan saat ini . Sentuhan teknologi dalam pengolahan limbah kelinci akan memberi nilai tambah yang tinggi bagi petani ternak mitra. Dari kegiatan ini target luaran yang telah dicapai yaitu kelompok mitra secara mandiri mampu memanfaatkan limbah kelinci padat maupun cair dengan baik menjadi “Pupuk Organik Padat” (POP) dan “Pupuk Organik Cair” (POC) yang dikemas dan ada label sehingga dapat dipasarkan lebih luas dan diharapkan dapat meningkatkan pendapatan kelompok mitra.

Abstract

Waste is unwanted residual material after the end of a process. The problem of waste has become a global issue that is a threat to the environment if it is not properly managed. Based on data from the Klungkung Regency Environmental Service in 2019, from four sub-districts in Klungkung Regency namely Dawan, Banjarangkan, Klungkung, and Nusa Penida, the volume of waste per day is more than 115,000 kg/person/day from a population of more than 230 thousand people, when compared production average waste production weighing 0.5 kg per person/day. Meanwhile, in terms of composition, the highest amount of waste is organic waste (68%), dust, rock and the like (8%), glass and plastic bottles 7%, followed by sheet plastic 5% and plastic 4%. The results of the analysis and depiction on the graph of the survey results were 4 (four) villages that had a high percentage of segregation, namely Semarapura Kauh Village (83.33%), followed by Semarapura Tengah (82.23%), followed by Semarapura Kangin Village (78.87. %) and Semarapura Kaja (75.21%). The results of this study prove that two locations have a very low level of sorting waste (less than 50%), namely Jempriring street in Semarapura Klod (47.61%), Rama street (42.11%), and Puputan street in Semarapura Kangin (44.73%). From this research, it can be concluded that public awareness of sorting waste in the two locations is still lacking.

Abstract

Timuhun Village, located in Banjarangkan District, Klungkung Regency, covers an area of 375 hectares with a population of 3,334 in 2021. Approximately 86.67% of the total land is utilized for agriculture, including rice fields, gardens, and dry fields, with a total agricultural area of 325 hectares. This village plays a significant role in food production, especially rice, supported by the irrigation system from Subak Timuhun, which utilizes the Manik Tirta Spring. However, challenges in water management arise due to the higher elevation of agricultural land compared to water sources, leading to difficulties in meeting the demands for clean water and irrigation. The Appropriate Technology of Hidropande is introduced as a solution to lift water from lower sources. This study aims to develop an integrated water management model by analyzing the residual water volume from the Manik Tirta Spring, determining the irrigation requirements for the paddy-cassava-paddy cropping pattern, and planning optimal water management strategies. Utilizing CROPWAT 8.0 software, this research estimates the water needs of crops based on various climatic and soil parameters. The results indicate that the highest irrigation water requirement reaches 41 mm/decade in December, while the lowest demand of 6.8 mm/decade occurs during the maturation phase of the plants. With calculations showing surplus residual water of 1.97 liters/second, the potential discharge from the Manik Tirta Spring can be maximized to support irrigation and meet clean water needs, alongside plans for developing a more efficient Hidropande pump. This study provides valuable insights into sustainable water management in Timuhun Village.

Abstract

Biochar is a material rich in carbon with the physical characteristics of porous biochar morphology. Biochar has the ability to retain nutrients and water, increase microbial life in the soil and overall increase soil fertility. Animal waste that often pollutes the environment can be converted into biochar through incomplete combustion to produce biochar charcoal which can be used to improve nutrient-poor agricultural soils. This service is carried out at the Satwa Winangun livestock farmer group, Tangkas Village, Klungkung Regency which takes place from May to July 2021. This PKM activity aims to increase the understanding and skills of partners to innovate in processing livestock waste into biochar. The method used to achieve this goal is through training, mentoring, and technology transfer with direct practice in the field. The transfer of technology for making biochar from animal waste received a good response from the trainees, especially because they had never made biochar. Through group strengthening and technology transfer with the PKM program, the trainees have been able to practice directly the process of making biochar and producing biochar fertilizer products that are ready to be applied to agricultural land.

Abstract

The provincial government of Bali has continuously encouraged livestock farming communities to form livestock groups especially the cows, through the Simantri program since 2009/2010 and is now known as Sipadu. In addition to this program, livestock groups are also formed independently by livestock farmers spread across Bali, one of which is the “Sato Luwih” livestock group in Kendran Village, Tegalalang-Gianyar, which requires guidance and assistance in empowering the resources they have, namely livestock and waste produced. The livestock group in Kendran village was only formed in early 2020, where its members have different abilities in raising livestock, both experienced and just starting to learn to raise livestock. Besides that, the existing resources in the form of cattle waste have not been utilized, on the one hand the waste still has the potential to increase group income if it is processed into organic compost. The problems faced by the group and group members are the lack of knowledge in the management of animal feed using rice straw, knowledge of technology for processing cow dung, both faeces and urine into organic fertilizer, and lack of understanding of the use of organic compost fertilizer in the farming system. Therefore, through PKM activities, it is necessary to provide assistance and transfer of applied technology to group members, so that the utilization of their resources can be utilized optimally. The methods used in this PKM activity are: observation and group discussion, counseling, and field practice. Group discussions were carried out by involving group administrators to determine the provision of activity materials and implementation schedules. Counseling was given to all group members about making fermented straw feed and making organic cow manure. While the practice is carried out directly by group members, and the results have been evaluated. The results of the PKM show that group members have been able to make fermented straw as animal feed and utilize livestock dung waste into organic fertilizer, so as to maintain the cleanliness of the cage environment. From this PKM activity, it can be concluded that there has been a change in the behavior of group members, namely knowledge and skills, while changes in attitude still need to be carried out by field observations.
