Abstract

This research was conducted from October to November 2024 in the greenhouse and laboratory of the Faculty of Agriculture, Science, and Health at Timor University. The purpose of this study was to determine the effect of the interaction between biochar compost residue and tofu waste POC on the growth and yield of pak choy plants. The study employed a completely randomized design (CRD) factorial experiment consisting of two factors. The first factor was biochar compost residue, and the second factor was tofu waste POC residue. The biochar compost factor consisted of three levels: 0% biochar compost, 10% biochar compost (0.4 kg biochar compost mixed with 3.6 kg soil), and 30% biochar compost (1.2 kg biochar compost mixed with 2.8 kg soil). The tofu waste POC factor also had three levels: 0 mL/L water, 100 mL/L water, and 200 mL/L water. These factors resulted in nine treatment combinations, each replicated three times, for a total of 27 experimental units. The results showed no significant interaction between biochar compost residue and tofu waste POC. However, the biochar compost residue alone had a substantial effect on plant growth parameters. This research provides valuable information for agriculture by helping to determine the use of biochar compost as a fertilizer and growing medium in pak choy cultivation, enhancing growth and yield.

Abstract

Penelitian ini bertujuan untuk menginvestigasi pengaruh kedalaman dan tempat aplikasi kompos biochar terhadap pertumbuhan dan hasil tanaman pakcoy (Brassica rapa L.) di lahan kering entisol. Percobaan ini menggunakan desain faktorial dengan dua faktor, yaitu kedalaman (5 cm, 15 cm, dan 25 cm) serta tempat aplikasi (olah lubang dan olah alur). Parameter yang diamati meliputi tinggi tanaman, jumlah daun, bobot segar total, bobot segar tajuk, bobot segar akar, panjang akar, bobot kering tajuk, dan bobot kering akar. Hasil analisiss varians menunjukkan bahwa tidak terdapat interaksi yang signifikan antara kedalaman dan tempat aplikasi pada seluruh parameter yang diamati. Namun, perlakuan tunggal memberikan pengaruh signifikan pada beberapa parameter. Kedalaman 5 cm dan 25 cm memberikan hasil terbaik pada parameter jumlah daun (21 HST) serta bobot segar akar. Pada perlakuan tempat aplikasi, pengolahan olah lubang secara konsisten menghasilkan pertumbuhan yang lebih baik dibandingkan dengan pengolahan olah alur, terutama pada tinggi tanaman (14-28 HST), jumlah daun, bobot segar total tanaman, bobot segar tajuk, bobot segar akar, panjang akar, dan bobot kering tajuk. Hal ini disebabkan olah konsentrasi kompos biochar pada pengolahan olah lubang lebih dekat dengan zona perakaran sehingga ketersediaan hara lebih optimal. Secara keseluruhan, penelitian ini menekankan pentingnya penentuan kedalaman dan metode aplikasi biochar untuk meningkatkan efisiensi pemanfaatan nutrisi pada tanah marginal. Aplikasi biochar pada kedalaman 5 cm atau 25 cm serta pengolahan olah lubang dapat menjadi strategi efektif untuk memperbaiki sifat tanah, meningkatkan ketersediaan unsur hara, dan meningkatkan produktivitas tanaman pakcoy di lahan kering entisol.

Abstract

Red chili (Capsicum annuum L.) is one of the most important vegetable commodities in the food industry and has many benefits. As a member of the Solanaceae family, red chili has high economic value and attractive market prospects. In addition to being consumed fresh as a mixture of cooking spices, chili fruit can also be preserved in various forms, such as pickles, sauces, chili flour, and dried fruit. This study aims to analyze the physical-chemical properties of soil in dry land used for chili cultivation (Capsicum annum L.) by the Taruna Jabalfarm Farmer Group in North Central Timor Regency. The parameters analyzed include soil texture, water content, organic matter, soil pH, and nutrient content such as nitrogen (N), phosphorus (P), and potassium (K). The results of the analysis showed that the soil has a sandy clay texture with a dominant sand content of 76.16%. The water content reaches 20.45%, organic matter is classified as low at 1.19%, slightly alkaline pH at 7.65%, and phosphorus content is very high at 62.26%, and potassium is quite good at 0.76%. Based on the results of this analysis, the soil requires additional processing in the form of organic matter and proper fertilization to support optimal growth of chili plants.

Abstract

This study aimed to examine the changes in the chemical properties of dryland Entisols upon the application of liquid organic fertilizer (LOF) from tofu waste and biochar, especially the content of C-organic, total N, total P, and P2O5 (available P), and the yield of pak choi. This study used a completely randomized factorial design. The first factor was the dose of tofu waste LOF (100, 200, and 300 ml/L water) and the second factor was the type of biochar (soil+rice husk biochar, soil+sawdust biochar, soil+rice husk biochar+ sawdust biochar). The combination of tofu waste LOF (100 ml/L) and the mixture of rice husk biochar and sawdust biochar (1:1:1) resulted in the most significant increase in C-organic (7.37%), total N (0.61%), total P (178.01 mg/100 g), and P2O5 (157.23 ppm) compared to other treatments. However, at a high dose of tofu waste LOF (300 ml/L of water), the contents of C-organic, total N, total P, and P2O5 tended to decrease, presumably due to the low pH of the tofu waste LOF. In terms of plant parameters, rice husk biochar treatment was the best for increasing the fresh weight of the shoots. This indicates that the optimal combination of LOF and biochar improved the chemical properties of Entisol analyzed after harvesting but did not increase the yield of pak choi at the beginning of application. However, rice husk biochar alone provided the best results for pak choi as an indicator plant. Keywords: C-organic, nitrogen, phosphorus, soil fertility, Timor

Abstract

Selama ini hampir semua KWT hanya melakukan kegiatan budidaya tanaman hortikultura maupun tanaman pangan namun belum melakukan kegiatan pengolahan produk. Hal ini yang menyebabkan jumlah stunting di Desa Tapenpah 21 orang. Untuk mengatasi hal demikian perlu adanya pangan sumber protein. Tempe merupakan sumber protein nabati yang cukup penting bagi masyarakat Indonesia yang difermentasi. Keunggulan tempe diantaranya daya cerna protein, karbohidrat dan lemaknya lebih baik; beberapa kandungan vitamin lebih tinggi, ketersediaan (bioavailabilitas) mineral menjadi lebih baik. Pelatihan pembuatan tempe dengan tujuan untuk menurunkan angka stunting. Selain itu, diharapkan menjadi nilai tambah bagi masyarakat Desa Tapenpah yaitu membuat tempe sendiri untuk dikonsumsi dan juga dapat dijual. Hal ini akan berdampak terhadap ekonomi masyarakat. Melalui KWT diharapkan wanita-wanita yang umumnya adalah ibu rumah tangga bukan saja dapat produktif dan mandiri dalam memenuhi kebutuhan pangannya tetapi juga produktif dan mandiri dalam pemenuhan kebutuhan gizi keluarga.  Oleh karena itu perlu adanya sosialisasi dan pelatihan pembuatan tempe kepada KWT sebagai penyedia makanan dalam rumah tangga. Sehingga dengan pemberian tempe, pertumbuhan berat badan penderita gizi buruk (Stunting) akan menurun dan diare menjadi sembuh dalam waktu singkat. Pengolahan kacang kedelai  menjadi tempe dapat menurunkan kadar raffinosa dan stakoisa yaitu suatu senyawa penyebab timbulnya gejala flatulensi (perut kembung).
