Abstract

Tomat (Solanum lycopersicum) merupakan jenis tanaman hortikultura yang umumnya ditanam secara luas di Indonesia. Badan Pusat Statistik melaporkan bahwa produksi tomat di Kota Batu, Jawa Timur dari tahun 2020 ke tahun 2021 mengalami penurunan. Produksi tomat pada tahun 2020 sebesar 117.501 kuintal dan mengalami penurunan pada tahun 2021 menjadi 76.745 kuintal. Penelitian ini direncanakan untuk dilakukan di Desa Torongrejo, Junrejo, Kota Batu, mulai dari bulan Juni hingga Agustus tahun 2023. Metode yang hendak dipilih berupa observasi langsung, perangkap jaring, perangkap yellow trap, dan perangkap pitfall trap. Penelitian ini dilaksanakan pada area pertanaman tomat yang telah ditanami dengan tanaman refugia selama periode 4 minggu. Observasi dilakukan sebanyak delapan kali, dengan interval dua kali dalam seminggu dan dimulai pada fase generatif yaitu umur tanaman tomat memasuki 6 MST (Minggu Setelah Tanam) hingga 10 MST. Parameter pengamatan meliputi jumlah hama dan musuh alami, identifikasi jenis, dan keanekaragaman hama dan musuh alami yang terdapat pada pertanaman tomat dengan penanaman refugia. Data hasil observasi dicatat dan diorganisir dalam tabel menggunakan Microsoft Excel. Analisis data kuantitatif keanekaragaman hama dan musuh alami dilakukan dengan menghitung indeks keanekaragaman jenis (H’), indeks kemerataan jenis (E), dan indeks asosiasi. Serangkaian pengamatan serangga pada pertanaman tomat telah dilakukan sebanyak 16 kali pengamatan dan terdapat 11 genus yang terdiri dari 5 ordo. Nilai indeks keanekaragaman hama dan musuh alami pada petak refugia dengan nilai 0,6435 lebih tinggi dibandingkan pada petak tanpa refugia. Sedangkan untuk nilai indeks kemerataan hama dan musuh alami juga ditunjukkan lebih tinggi pada petak refugia dengan nilai 0,2683. Hasil nilai x hitung indeks asosiasi setiap hama dan musuh alami yang ditemukan di penelitian ini menunjukkan tidak adanya asosiasi antara setiap hama dan musuh alami.

Abstract

The objectives of this study were to determine whether the application of kasgot organic fertilizer can increase the growth and yield of edamame, determine whether the effectiveness of kasgot organic fertilizer is better than non-kasgot organic fertilizer, and determine the best combination of kasgot organic fertilizer and non-kasgot organic fertilizer in increasing the growth and yield of soybeans. The treatments used: no organic fertilizer (control) (P0), non kasgot solid organic fertilizer (P1), non kasgot liquid organic fertilizer (P2), kasgot solid organic fertilizer (P3), kasgot liquid organic fertilizer (P4), non kasgot solid and liquid organic fertilizer (P5), kasgot solid and liquid organic fertilizer (P6), and non kasgot organic fertilizer and kasgot organic fertilizer (P7). The research findings indicate that the application of organic fertilizer enhances the growth and yield of soybeans compared to the control. Specifically, the combination of solid kasgot organic fertilizer (5 t ha-1) with liquid kasgot (50 ml L-1 water) produced the best plant growth and number of pods plant-1. It was also reported that the variables of number of branches, plant height, and plant wet weight significantly positively correlate with the number of pods plant-1.

Abstract

Mango (Mangifera indica L.) can be developed through plant propagation by the method of shoot-tip grafting. The problem that often take place is the distance between the mother tree and the location of the connection that is far apart, so it takes a long time and is tough to finish within one day. This research aims to obtain a combination of shelf life and types of scion wrapping materials on the growth of mango seedlings. The research conducted in April - August 2023 at UPT Horticultural Seed Development using Complete Randomized Design (CRD) with 2 factors 3 replications. The first factor is storage time (L) (0 days, 2 days, 4 days, and 6 days) and the second factor is the type of wrapping materials (M) (without packaging, banana frond wrapping, newspaper wrapping, and coconut husk wrapping). Parameters include the time at which shoots appear, the percentage of viable grafting, the length of the shoots and the total number of leaves. The results showed that in general the percentage of success was 70%. The treatment of storage time and type of entres wrapper did not affect the percentage of live grafting, but at a storage time of 2 days, the fastest results were obtained at the time of bud emergence and the longest results in bud length. Keywords: Entry, Length of Storage, Type of Wrapping, Mango Shoot Grafting

Abstract

The decline in domestic productivity of longan (Dimocarpus longan L.) occurred due to increased imports. Efforts to get seedlings quickly without requiring a long time can be done by vegetative propagation of longan (shoot grafting). The purpose of this study was to obtain a combination of soaking time with the right concentration of young coconut water on the growth of shoots. The research was conducted from April to July 2023 at Kebun Mangga Pohjentrek, Pasuruan. This study used a 4x4 factorial pattern arranged in a completely randomized design (CRD) with three replications.  There are 2 factors studied, the first factor is the duration of immersion of the scion consisting of 4 levels (0, 2, 4, 6 hours). The second factor is the concentration of young coconut water consisting of 4 levels (0%, 25%, 50%, 75%). The parameters observed were bud break, percentage of finished grafts, bud length, bud diameter, and number of leaves. The results showed that there was an interaction between the combination of soaking time of 4 hours with a concentration of 25% on the length of shoots at 28 DAG. Effective growth is obtained at a soaking time of 4 hours and a concentration of 25% young coconut water on the parameters of shoot length and shoot diameter.Keywords : scion, longan, concentrate coconut water, shoot grafting

Abstract

The growth and production of hydroponic water spinach using liquid organic fertilizer and appropriate planting media determines the success of the plant. The aim of this research is to determine the effect of liquid organic fertilizer (LOF) substitution types and planting media on the growth of water spinach (Ipomoea reptans) production. Data collection was carried out in the month 23 Februaty – 30 March 2023 in Pudakpayung village, Banyumanik District, Semarang City. Treatments were arranged using a completely randomized design with 2 factors. Factor 1 is the planting medium in 2 level, M1 = Rockwool dan M2 = Cocopeat, and factor 2 is the substitution of liquid organic fertilizer in 4 levels, N1 = 4 ml/l AB mix, N2 = 3 ml/l AB mix + 2 ml/l POC, N3 = 2 ml/l AB mix + 3 ml/l POC, dan N4 = 4 ml/l POC. Each treatment was carried out in 3 repetitions so that there were 24 experimental units. The parameters observed were plant height, number of leaves, root length, shoot fresh weight, root weight, biomass weight, and leaf color. The data was analyzed for variance and further tested using the honest real difference (BNJ) at the 5% level. The research results showed that the use of LOF of rice waste and papaya fruit could substitute AB mix at a concertation of 2 ml/l AB mix + 3 ml/l LOF or 50%. However, the use of 100% POC cannot replace AB mix in growth and production of water spinach. Keywords : AB mix, cocopeat, liquid fertilizer, rockwool, rice, papaya fruit, waste

Abstract

Food security is a challenge in almost all developing countries with low to middle-income levels, including Indonesia. Rice, as one of the primary food sources and a pillar of Indonesian society, has shown a decline in both production and productivity in recent years. This decline in rice production and productivity is attributed to the conversion of productive rice fields due to the high input costs required for each planting season. This situation arises from the limited ability of farmers to make accurate production estimates over large areas and within short timeframes. This research was conducted in Sambas Regency, West Kalimantan, in 2024 with the goal of estimating rice production using satellite imagery technology and geographic information systems (GIS) in Sambas Regency. The data used were obtained through sampling methods in each sub-district, and the imagery data were acquired from Landsat 8 satellites, processed using the Normalized Difference Vegetation Index (NDVI) combined with GIS, and analyzed using QGIS 3.36.3 software. The analysis indicates that the coefficient of determination for rice productivity is highly influenced by the NDVI value, which is 90%, with the formula y = 3.9453x + 0.5287. Consequently, the average rice production in Sambas Regency in 2024 is 2.36 tons/ha.Keywords : imagery, NDVI, Qgis, rice

Abstract

Orchid plantlets are expected to be able to adapt and grow under optimal conditions during the acclimatization period. Selecting appropriate planting media and providing proper nutrition is one of the efforts that can be made to increase the success of high growth of Dendrobium, sp orchid plantlets during the acclimatization period. The aim of this research was to identify the appropriate planting medium and concentration of rooting starter solution to support the growth of Dendrobium sp orchid plantlets during acclimatization. This research was carried out from March to July 2022 at the Bangka Belitung University Experiment and Research Garden. This study used a factorial randomized block plan. The first factor is the planting medium; (M1) pine bark, (M2) Paraserianthes falcataria bark, (M3) acacia bark, and (M4) fern. The second factor is the industrial growth concentration 20 ml/l (K0) and 10 ml/l (K1). The results showed that the acclimatization of Dendrobium sp orchid plantlets was successful as seen from the large growth in plantlet height and the emergence of new shoots. The treatment that produced the highest growth of Dendrobium sp orchid plantlets during the acclimatization period was fern media and the best rooting starter concentration was 20 ml/l. The combination that showed the highest growth in Dendrobium sp. orchid plantlets during the acclimatization period was fern media + 20 ml/rooting starter. Key words:   Dendrobium, tree bark, acacia bark, fern, rooting starter, Paraserianthes
