Abstract

Suboptimal soil conditions can lead to reduced latex production and quality. One of the main factors influencing latex production is soil fertility, where fertile soil with adequate nutrient content can enhance latex yield. One of the efforts to improve production is through proper fertilization, where the dosage and timing of phosphorus (P) and potassium (K) application must align with the needs of the rubber plant and the condition of the soil. By using appropriate P and K fertilizers, rubber farmers can increase both latex yield and quality. This research was conducted using a factorial experiment with a randomized complete block design (RCBD) and three replications. The first factor was the amount of TSP fertilizer, divided into four categories: P0 = without TSP application per tree, P1 = 175 g per tree, P2 = 200 g per tree, and P3 = 225 g per tree. The second factor was the dose of KCl fertilizer, consisting of four categories: K0 = control, K1 = 200 g per tree, K2 = 250 g per tree, and K3 = 300 g per tree. The findings indicated that TSP fertilizer application had a significant effect on dry rubber content, while KCl doses did not show a significant effect on latex volume, wet latex weight, dry latex weight, or dry rubber content.

Abstract

Abstract Banana (Musa sp) is one of the tropical fruit types originating from Southeast Asia. Bananas have a high enough potential to be managed intensively, because they have become an export and import trading business in the international market.Tissue culture is a method of plant propagation conducted vegetatively in a synthetic medium under sterile conditions (in vitro). Acclimatization is a period of adaptation of plantlets from in vitro (controlled environment) culture media to the open spaces before being planted in the field. One of the factors that influence the success of plantlets acclimatization is the use of the right media composition so that it can produce good plants. This study was conducted to determine the effect of growth of bananas (Musa acuminnata cv. Barangan) resulting from acclimatization with the use of variations in cow manure growing media. The research was using a completely randomized design (CRD) with a single factor. The factor was the treatment of planting media composition (soil: husk: cow manure) consisting of 8 levels: S1 = 1:1:1, S2 = 1:1:2, S3 = 1:2:1, S4 = 1:2:2, S5 = 2:1:1, S6 = 2:1:2, S7 = 2:2:1, S8 = 4:2:1. Variables observed included plant height, leaf number, leaf length, leaf width, and stem diameter. Data were analyzed by analysis of various test levels of 5% and further analysis of Duncan's Multiple Range Test (DMRT). The results showed that the treatment comparison of the composition of the planting medium, soil: husk: cow manure did not significantly affect the growth of barangan banana plants. In the treatment of comparison of the composition of soil: husks: cow manure (1:2:1) gives higher results and better results on all variable variables observed Keywords: Growth; manure; tissue culture

Abstract

Papaya is a horticultural commodity with many benefits and high economic value for the people of Indonesia. California papaya is a favorite variety in Indonesia due to its various advantages. Effective and agroecological cultivation techniques are needed to increase production. This study aims to determine the optimal dosage of mycorrhizae and manure in increasing papaya plant growth. This study was conducted in the dry land of Tawengan Village, Sambi District, Boyolali Regency, at 180 m above sea level. The research used a factorial Complete Randomized Block Design (CRBD) with 3 blocks as replications. The first factor was mycorrhizae with 3 levels: 0 g/plant, 75 g/plant, and 150 g/plant. The second factor was manure with 4 levels of application doses: 0 kg/plant, 3 kg/plant, 6 kg/plant, and 10 kg/plant. The results showed that the application of mycorrhizae and manure can improve the characteristics of plant height, stem diameter, and crown width. The mycorrhizal application dose of 150 g/plant and the application of 5.7 kg/plant of manure is the optimal dose to increase papaya growth, which will support increased production.

Abstract

Keberadaan ruang terbuka hijau perkotaan penting untuk menciptakan lingkungan yang nyaman di tengah isu pemanasan global dan peningkatan populasi. Salah satu faktor penting yang memengaruhi kenyamanan pengunjung taman kota adalah kondisi iklim mikro. Penelitian ini bertujuan untuk menganalisis kondisi iklim mikro, menghitung indeks kenyamanan (THI), dan menganalisa persepsi pengunjung terhadap tingkat kenyamanan pada Taman Ulin, Taman PAUD, dan Taman Pintar di Kota Tenggarong, Kabupaten Kutai Kartanegara. Data iklim mikro (intensitas cahaya, suhu udara, dan kelembapan udara) diukur langsung di lapangan, sedangkan persepsi pengunjung dikumpulkan melalui survei. Hasil penelitian menunjukkan tiga taman kota yang diteliti memiliki kondisi iklim mikro yang berbeda disebabkan perbedaan jumlah vegetasi yang ditanam pada setiap taman kota. Indeks kenyamanan di Taman Ulin (27,66), Taman PAUD (28,02), dan Taman Pintar (27,88) termasuk dalam kategori “nyaman”. Persepsi pengunjung terhadap kenyamanan berdasarkan indikator iklim memiliki rata-rata penilaian secara berturut-turut di Taman Ulin sebesar 4,32 (kategori sangat baik), Taman PAUD sebesar 2,84 (kategori kurang baik), dan Taman Pintar sebesar 4,13 (kategori baik). Informasi kondisi iklim mikro dan persepsi pengunjung serta tingkat kenyamanan pada taman kota dapat dijadikan bahan pertimbangan dan menjadi rekomendasi bagi pemerintah daerah dalam pengelolaan dan perencanaan taman kota yang lebih baik, termasuk penempatan vegetasi, kawasan teduh, dan fasilitas pendukung lainnya, dengan mempertimbangkan kebutuhan masyarakat dan prinsip-prinsip kenyamanan iklim.

Abstract

Pengaplikasian amelioran dan pupuk NPK pada tanah ultisol dapat meningkatkan kualitas tanah secara fisik dan kimia. Penelitian ini bertujuan untuk mengkaji peran amelioran dan pemupukan NPK dalam meningkatkan produktivitas jagung hibrida pada tanah ultisol. Penelitian dilakukan dengan menggunakan rancangan acak kelompok faktorial. Perlakuan amelioran sebagai faktor pertama dengan 4 taraf yaitu a0, tanpa amelioran; a1, biochar sekam padi 5 ton ha-1; a2, lumpur sawit 5 ton ha-1; a3, gabungan biochar sekam padi dan lumpur sawit 10 ton ha-1. Pemupukan NPK sebagai faktor kedua yang terdiri dari 5 taraf yaitu p0, tanpa pupuk NPK; p1, 150 kg ha-1; p2, 200 kg ha-1; p3, 250 kg ha-1; p4, 300 kg ha-1. Hasil penelitian diperoleh bahwa interaksi perlakuan amelioran dan pemupukan NPK dapat meningkatkan variabel tinggi tanaman, diameter tongkol serta panjang tongkol. Perlakukan pemupukan dapat meningkatkan volume akar, berat pipilan basah, dan berat kering pipil. Perlakuan amelioran dapat meningkatkan variabel volume akar. Perlakuan NPK 150 kg ha-1 serta gabungan biochar sekam padi 5 ton ha-1 dan lumpur sawit 5 ton ha-1 merupakan dosis terbaik yang dapat meningkatkan produktivitas tanaman jagung pada tanah ultisol. Kata kunci: amelioran, kesuburan tanah, produksi jagung, tanah ultisol
