“…The land snails of Stylommatophora do not move far over their lifetime and are sensitive to calcium availability for their shell formation and development (Zuliantoni et al 2022). The small number of land snail found in this experiment could be an indicator that the soil is low in calcium (Sari 2021) with pH of 4.6 and low in N, P, and K. The earthworm of the order of Oligochaeta is mostly burrow into the soil and result in a very small amount of individual found in the trap during this experiment. Earthworm has an avoidance behavior towards pesticides (Yang et al 2018).…”

Abstract. Chaniago I, Yulistriani, Umami IM, Bukhari ZZ. 2023. Soil macrofauna diversity and weed dynamics in response to different methods of weed control in smallholder rubber farming. Biodiversitas 24: 3106-3113. Weeds interference in rubber farmland may reduce latex yield. Farmers apply herbicides to control weeds. However, the herbicide not only controls weed but also affects the presence of soil macrofauna. A study has been conducted to determine the effect of different method of weed control on soil macrofauna and weeds at smallholder rubber farming at Pulau Punjung, Dharmasraya District, West Sumatra, Indonesia. The experiment was conducted in a completely randomized block design with 6 treatments and 4 pseudo-replications. Treatment was mechanical control, without weed control, and 4 doses of herbicide glyphosate+metsulfuron-methyl (1.5 L ha-1 + 15 g ha-1, 2 L ha-1 + 15 g ha-1, 2.5 L ha-1 + 15 g ha-1, 3 L ha-1 + 15 g ha-1) with 400 L ha-1 of volume. Pitfall traps were used to collect the soil macrofauna. Data were analysis with ANOVA for weed and soil macrofauna in response to different methods of weed control. Results demonstrated that the application of glyphosate+metsulfuron-methyl herbicide significantly suppressed weeds higher than that of other methods of weed control (p<0.05). Para grass (Brachiaria mutica (Forssk.) Stapf) was the most dominant weed but has been affected most by 3 L ha-1 + 15 g ha-1 herbicide mixture. Soil macrofauna of the order Hemiptera was affected most by the application of herbicide with a total reduction of 71.58% of number of individuals at 12 weeks after application of herbicide. In general, different weed control methods resulted in varied numbers of orders and individuals of the soil macrofauna.

“…Najiyati & Danarti (1999) menyatakan bahwa tanaman kopi menghendaki tanah yang gembur, subur, dan kaya bahan organik agar sistem perakarannya tumbuh dengan baik dan dapat mengambil unsur hara sebagaimana mestinya. Sarawati (2015) Media tanam yang digunakan untuk penelitian ini yaitu media tanam tanah (kontrol), arang sekam, cocopeat, serbuk kayu dan sekam. Kebanyakan orang sering menggunakan tanah sebagai media tanam karena tanah baik bagi perakaran tanaman, gudang unsur hara, dan dapat menyediakan air serta udara untuk keperluan tanaman.…”

Tanaman kopi robusta dapat di perbanyak secara vegetatif dengan cara stek batang agar tanaman yang di hasilkan dapat memproduksi karakteristik yang sama dengan induknya. Keberhasilan perbanyakan menggunakan stek batang harus diimbangi dengan media tanam yang tepat karena dapat berpengaruh terhadap pertumbuhan stek batang. Media tanam yang di gunakan harus media tanam yang berpori, gembur, serta di dukung dengan drainase dan sirkulasi udara yang baik bertujuan agar akar yang baru dapat menembus media tanam untuk menacari makan. Penelitian ini bertujuan untuk mengetahui pengaruh perbandingan media tanam terhadap hasil pertumbuhan stek batang tanaman kopi robusta pada fase pembibitian dan memperoleh perbandingan media tanam yang tepat yang mampu memberikan pertumbuhan stek batang tanaman kopi robusta pada fase pembibitan yang paling baik. Bahan yang di gunakan yaitu tanaman indukan kopi robusta, polybag, tanah, cocopeat, arang sekam, serbuk kayu, pupuk kandang, ZPT root up, plasik sungkup, greenhouse. Penelitian ini menggunakan RAK 1 faktor yaitu: berbagai perbandingan media tanam. Terdapat 5 perlakuan, 4 ulangan, dan memiliki 5 unit sampel sehingga ada 100 bahan stek batang. Hasil penelitian ini menunjukan perbandingan antara tanah : cocopeat : pupuk kandang dan tanah : serbuk kayu : pupuk kandang berpengaruh nyata terhadap hasil pertumbuhan stek batang tanaman kopi robusta. Perbandingan media tanam berpengaruh nyata terhadap hasil pertumbuhan stek batang tanaman kopi robusta.

“…Pada penelitian terdahulu, Pratiwi et al (2019) menyatakan bahwa pemberian POC urine sapi memberikan pengaruh lebih baik terhadap panjang batang tebu daripada perlakuan kontrol. Unsur hara dan kandungan hormon IAA yang terdapat dalam POC urine sapi diduga mampu melakukan pemanjangan dan diferensiasi sel batang sehingga membentuk proses pemanjangan tunas (Sapri & Febrialdi, 2021). Pemanjangan tunas juga dapat disebabkan oleh pembesaran sel karena masuknya auksin ke dalam sel.…”

Sugarcane (Saccharum officinarum L.) is an important plantation commodity as the main raw material for producing sugar consumed in Indonesia. One of the varieties cultivated is VMC 86-550, but one of the technical obstacles to its cultivation is the slow and non-uniform growth of the seeds. Therefore, one effort to maximize the growth of budset seed varieties requires proper nutrition and contains growth-promoting hormones. Therefore, this study aims to determine the response of giving liquid organic fertilizer (LOF) from cow urine to the growth of VMC 86-550 sugarcane seedlings using the budset method. To find out the purpose, this study used a factorial randomized block design with a concentration factor of LOF of cow urine consisting of five levels (0%, 10%, 15%, 20%, and 25%). The second factor is the application frequency which consists of once every 2 weeks and once every 4 weeks, so there were 10 treatments and repeated three times. This study used a completely randomized factorial design and was analyzed using ANOVA if there was a significant influence followed by Duncan Multiple Range Test (DMRT) at a 5% level using SPSS 20 software. Observation variables included plant height, stem diameter, number of leaves, number of tillers, and root length of sugarcane seedlings up to 90 HST. The results showed that the addition of cow urine LOF had an effect on the growth of sugarcane seedlings, both from the concentration and frequency of application, but the combination of the two did not have a significant effect on all observation variables.
