Soybeans become a source of plant protein and an essensial food ingredient in Indonesia. Extreme climate change causes weather changes; the impact is a long dry season which results in drought. Efforts to deal with drought stress are carried out using drought-tolerant soybean varieties that drop of production can be suppressed. The purpose of the study is to study growth responses for several different soybean varieties with drought-stricken conditions. The research was conducted from October 2019 to January 2020 at the Green House Agroecotechnology Laboratory of the Faculty of Agriculture, University of Sultan Ageng Tirtayasa, Banten. Factorial randomized block design method was then used which consists of two factors and three repetition. The first factor were that the Varieties consists of V1: Argo mulyo variety; V2: Deja 2 and V3 varieties: Dena varieties. The second factor was drought percentage comprising k1: 100% ATT (Groundwater Available); k2: 80% ATT, k3: 60% ATT and k4: 40% ATT. The results showed that differences in varieties and drought stress did not significantly affect the growth and yield of soybean crops. Argo Mulyo varieties are superior to drought stress compared to Deja 2 and Dena varieties from the weight of 100 seeds. No interaction of different soybeans varieties treatment and drought stress on all observation parameters.

The objectives of this activity are: 1. increasing beef cattle productivity through early pregnancy detection technology in Sungai Kunyit Village, South Solok District, 2. increasing community knowledge and skills in the application of early pregnancy detection technology, and 3. transferring science and technology from tertiary institutions to the community in Sungai Kunyit Village, South Solok District. This activity was carried out in July 2019 in Sungai Kunyit Village, South Solok District. In this activity involved lecturers, students at Andalas University, breeders, and the community in Sungai Kunyit Village, South Solok District. While the methods used are lecture, question and answer, demonstration, coaching, and evaluation methods. While coaching and evaluating the activities carried out continuously. The results obtained from this activity are 1. the community and breeders are able to implement early pregnancy detection technology in beef cattle, 2. the high response of the community and breeders both in the extension activities and demonstration of early pregnancy detection technology, and 3. increased income of the community and breeders in Sungai Kunyit Village, South Solok District. This activity was attended by community leaders, village apparatus, and Sungai Kunyit village extension officers, South Solok. From the results of the action, it can be concluded that this activity is categorized as very successful and provides benefits to the community. This can be seen at the time when the events of the breeders/farmer groups and the community are substantial towards the development of beef cattle business.

Kegiatan pengabdian pada masyarakat ini dilakukan pada usaha peternakan sapi potong di kelompok Taruko Saiyo, Kelurahan Cupak Tangah, Kecamatan Pauh Kota Padang. Permasalahan dikelompok sasaran adalah adopsi inovasi oleh peternakan rendah karena kurang mendapat penyuluhan dan motivasi usaha anggota kelompok menurun. Tujuan dari kegiatan ini adalah 1) Introduksi inovasi peternakan dan  2) Meningkatkan motivasi angota kelompok Taruko Saiyo dalam menjalankan usaha peternakan sapi Potong. Transfer pengetahuan pada kelompok sasaran di lakukan dengan menggunakan metode penyuluhan melalui pendekatan ceramah dan sosialisasi. Hasil dari kegiatan adalah terjadi perubahan perilaku sasaran terutama pada aspek koqnitif, yaitu  perubahan pengetahuan anggota kelompok Taruko Saiyo dari tidak mengetahui jenis jenis inovasi peternakan menjadi tahu, baik itu inovasi pada aspek pakan, aspek reproduksi maupun inovasi dalam bentuk program dan kebijakan pemerintah. Terjadi peningkatan motivasi anggota kelompok sasaran yang tergambar dari bergabungnya kembali anggota kelompok yang sebelumnya sudah tidak aktif dari keanggotaan dan terpilihnya kepengurusan baru di kelompok Taruko Saiyo. Kata Kunci: Introduksi Inovasi, Inovasi Peternakan, Motivasi Usaha, Perbaikan Usaha, Usaha Peternakan ABSTRACT This community service activity is carried out in the beef cattle business in the Taruko Saiyo group, Cupak Tangah Village, Pauh District, Padang City. The problem in the target group is the low adoption of innovation by farms due to lack of counseling and decreased business motivation of group members. The objectives of this activity are 1) Introducing livestock innovations and 2) Increasing the motivation of the Taruko Saiyo group members in running a beef cattle business. Transfer of knowledge to target groups is carried out using extension methods through lecture and socialization approaches. The result of the activity is that there is a change in target behavior, especially in the competitive aspect, namely a change in the knowledge of the Taruko Saiyo group members from not knowing the types of livestock innovations to knowing, both innovations in the aspects of feed, aspects of reproduction and innovation in the form of government programs and policies. There was an increase in the motivation of target group members as reflected in the rejoining of group members who had previously been inactive from membership and the election of new management in the Taruko Saiyo group.

This research used a Randomized Block Design with two factors, the first factor was waterlogging of four levels: 100% Soil Water Available (SWA), 125% SWA, 150% SWA, 175% SWA. The second factor was nitrogen fertilizer of three levels: 0 kg ha -1 ), 25 kg ha -1 ), 50 kg ha -1 with three replication. The results showed that treatment of waterlogging affects the number of soybean plant leaves at five Weeks After Planting (WAP). The number of leaves in the waterlogging treatment is 175% less compared to the waterlogging of 100% SWA, 125% SWA, and 150% SWA. Nitrogen treatment affects the stomata length of soybean crops. Nitrogen fertilizer doses of 50 kg ha -1 have a lower stomata length compared to doses of 0 kg ha -1 and 25 kg ha -1 . There is interaction in the treatment of waterlogging and nitrogen fertilizers at a plant height of 2 WAP.

Rice has different varieties, with each variety possessing diverse physical and chemical characteristics. The objective of this study was to analyze the physicochemical properties of several Indonesian local rice varieties.
