Abstract

Perubahan fisika dan kimia dalam timbunan kompos diteliti selama proses pengomposan limbah pembuatan botol yang terkontaminasi oleh gemuk (grease). Temperature awal menunjukkan peningkatan diikuti oleh penurunan secara bertahap pada akhir proses pengomposan. C:N rasio dan bahan tambahan nampaknya mempunyai pengaruh yang paling nyata dalam memproduksi temperatur tinggi. Proses pengomposan selama lima (5) bulan tidak menghilangkan kontaminan sampai batas yang dipersyaratkan. Oleh karena itu diperlukan waktu tambahan guna mengurangi kontaminan sampai level yang ditetapkan. Proses pengomposan ini berhasil dalam menghasilkan temperatur yang meningkat, namun parameter yang menyebabkan kenaikan temperatur tersebut masih belum jelas.

Abstract

Growth media waste of white oyster mushroom cultivation can be used as ruminant feed. We observed the nutrient content of the growth media waste. The focus is on the protein, carbohydrate, mineral and crude fiber. The protein, calcium and phosphor content of white oyster mushroom growth media waste is higher than the protein content in the media before it was used for mushroom cultivation. However, the fat content is lower after the media was used than control (the media before it was used). The difference is caused by microorganism degradation. The growth media waste can be used as ruminant feed up to 75 % of total forage dry matter without any negative effect.

Abstract

Agriculture Extension and Communication undergraduate study program (S1 Agribusiness) at Universitas Terbuka (UT) has been opened since 2004.Starting from the registration period of 2012.2, Agribusiness Study Program has been issuing practicum guide as a guidance for students to do their practicum indepedently. This study aims to get students' perceptions of self-practicum management regarding the implementation of independent practicum guidance and analyzet he constraints that exist in the field experienced by the students. The survey is conducted on students who took practicum during the registration periods of 2013.1 to 2014.2. A survey is conducted by questionnaires. The questionnaire asks three aspects of practicum implementation which are practicum guidance aspect, material aspect and of practical support services aspect. Students' perceptions regarding practical implementation are positive, although there are tendencies of having difficulties in understanding the practical guidelines. They feel the guideline is not systematic and lack of details.. The language used in the guideline regarded by most non-extension students as difficult to understand. Students expect the practical guide to be more detailed and clear. They said that it would be easier if at any part of the report is written in great detail of what should they fill, there should be an explanation of how the repot will be rated. Although in general students have positive perceptions, there were some students who had dificulties in accessing practical guidance, obtaining materials and tools, and having qualified and competent instructor. Another constraint felt by most of the students is the marks sometimes received behind the schedule. Mulai masa registrasi 2012.2 Program Studi Agribisnis Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Terbuka (FMIPA-UT) menerapkan pelaksanaan praktikum mandiri dan memberlakukan Panduan Pelaksanaan PraktikumMandiri yang dirancang sebagai panduan bagi peserta praktikum untuk melaksanakan praktikum secara mandiri. Penelitian ini bertujuan untuk mendapatkan datapersepsi mahasiswa terhadap pedoman dan pelaksanaan praktikum mandiri, serta kendala-kendala di lapangan yang dialami oleh mahasiswa.Survei dilakukan terhadap mahasiswa yang mengambil praktikum pada masa registrasi 2013.1 sampai dengan 2014.2 dengan meminta mereka mengisi kuesioner. Kuesioner menanyakan tiga aspek dari pelaksanaan praktikum yaitu aspek pedoman praktikum, aspek materi praktikum dan aspek layanan penunjang praktikum. Persepsi mahasiswa terhadap pelaksanaan praktikum cukup positif, meskipun ada kecenderungan mahasiswa mengalami kesulitan memahami pedoman praktikum. Mereka merasakan panduan praktikum kurang sistematis dan detail. Bahasa yang digunakan dalam panduan oleh sebagian mahasiswa non penyuluh dianggap sulit dipahami. Mahasiswa mengharapkan panduan praktikum dibuat lebih detail dan jelas. Mereka mengatakan akan lebih mudah jika pada setiap bagian laporan dituliskan secara detail hal-hal yang harus mereka masukkan, jika perlu diberikan kisi-kisi penilaian laporan. Meskipun secara umum persepsi mahasiswa terhadap praktikum positif, namun masih ada sebagian mahasiswa yang mengalami kendala dalam hal mengakses panduan praktikum, memperoleh bahan dan alat praktikum serta tidak mudah mendapatkan instruktur yang kompeten. Kendala lain yang dirasakan sebagian besar mahasiswa adalah nilai praktikum yang tidak diterima sesuai jadwal.

Abstract

During Covid-19 pandemic, online learning has been implemented as a strategic solution by many universities to prevent the spread of the Covid-19. This new teaching learning practice has encouraged researchers to conduct a survey of student readiness and satisfaction with the online learning services. This study aims to uncover two strategic issues including factors that influence student readiness and satisfaction and the level of student readiness and satisfaction dealing with online learning services. This research employs quantitative research methods using online surveys and involving all students who were actively registered in 2019 and 2020 both UT and non-UT students who participated in online learning services. Samples, however, were taken from all respondents covering western, central, and eastern Indonesia. It was discovered that structurally, supporting aspects contribute around 37%, prospect aspects 25%, benefit aspects 23%, and constraint aspects 11%, towards a dimension of the formation of participants' online learning perceptions. The findings show that participants have quite different views on supporting aspects, benefits, or prospects of online learning from the aspects of constraints. The relationship among the three distribution groups of variable categories shows three quite different positions in terms of participants' perceptions on online learning, namely accepting, moderate or opposing positions. Their opinion on online learning programs, during the Covid-19 outbreak, participants differed in their opposing positions on the one hand and moderate positions on the other, especially regarding costs, trends, and prices of devices/supporting equipment for online learning participants.

Abstract

Potensi bahan pakan ternak yang ada di desa Tegal Kecamatan Kemang Kabupaten Bogor, Jawa Barat secara optimal belum mampu untuk mendukung produktivitas dan reproduktivitas ternak yang diusahakan, karena nilai nutrisi dan kecernaannya yang rendah. Kelemahan pemanfaatan limbah pertanian sebagai pakan adalah kandungan seratnya yang tinggi (35 - 45%) dan kadar proteinnya yang rendah (1,8 – 3,5%). Oleh karena itu dalam pemanfaatannya perlu dilakukan pengolahan. Peternak di wilayah Tegal, kecamatan Kemang belum terbiasa dengan teknologi untuk meningkatkan produktivitas ternaknya, khususnya teknologi pakan. Kegiatan pengabdian kepada masyarakat dengan teknologi Amonia Fermentasi (Amofer) menghasilkan pemanfaatan limbah pertanian sebagai pakan alternatif untuk ternak kambing. Teknologi amonia-fermentasi dapat meningkatkan produktivitas ternak karena dapat meningkatkan pertambahan bobot badan dan memperbaiki reproduksi ternak. Upaya peningkatan reproduksi ternak kambing dapat ditempuh juga melalui pemberian pakan penguat/tambahan yang dinamakan flushing. Dengan flushing mempercepat waktu terjadinya estrus/birahi bagi kambing lokal calon induk menjadi sekitar 10 bulan. Melalui teknologi flushing terjadi estrus yang lebih cepat (menjadi 3 bulan pasca beranak), sehingga dihasilkan 3 kali beranak dalam 2 tahun. Selain itu dengan pakan flushing, akan meningkatkan goat crop 10 – 20%, sehingga akan mempercepat pertambahan populasi kambing lokal dengan kualitas yang baik. Peningkatan kemampuan reproduksi ternak kambing lokal akibat pemberian pakan flushing pada akhirnya akan mampu meningkatkan populasi ternak kambing lokal secara lebih cepat, karena kambing lokal akan efisien dalam aktivitas reproduksinya. Peningkatan efisiensi reproduksi ini jelas akan meningkatkan populasi ternak di suatu wilayah, sekaligus peningkatan pendapatan masyarakat.

Abstract

Kalikesur Village, located in the Kedungbanteng District of Banyumas Regency, possesses significant prospects in agriculture and animal husbandry. Typically, the villagers continue to rely on forage fodder, such as grass and agricultural waste, to feed their poultry and cattle. Hence, the objective of our community activity is to acquaint the inhabitants of Kalikesur Village with the Azolla plant as a substitute feed and as a material for bio-organic fertilizer. We also want to teach cultivating methods so that an Azolla business group can be established. Getting to know one another, sharing insights on the value and advantages of Azolla for animal feed and bio-organic fertilizers, constructing basic bio-flocks (ponds), learning how to cultivate and harvest Azolla, creating fertilizer with Azolla as a base, and initiating new Azolla marketing campaigns on social media were some of the activities that took place. One of the program's many results is the technology transfer for growing Azolla, which may be used as a bio-organic fertilizer and a nutritional feed alternative. Additionally, it creates instructions for growing Azolla and using it as bio-organic fertilizer and animal feed. Additionally, the program provides manuals on the business analysis of Azolla. It contributes to the increase in livestock production, thereby enhancing the income and welfare of community service partners and the surrounding region.
