Abstract

Ultisols are the largest order in Indonesia among other acid soils, namely around 41,919 million ha, with the problem of insufficient P availability in soil for plant growth, requiring special treatment to increase available P in the soil. This study aims to examine the effect of compost and rock phosphate in increasing the availability of P in Ultisols. The research was conducted in April–May 2016 at the Laboratory of Chemistry and Soil Fertility, University of Hasanuddin, Makassar. The study used a randomized block design and was carried out by incubating straw compost, gamal leaves, cow dung and rock phosphate in Ultisol soil with a soil weight of 300 g. The research results show that 15th day of incubation showed the highest available P of 12.97 ppm with a pH of 5.15 in the KJ575%+KS525%+BF treatment, while on the 30th day of incubation the available P increased 17.45 ppm in the rock phosphate treatment with a pH of 5.58. The application of rock phosphate and SP36 reduced Al-P, Fe-P, and Ca-P, while the application of organic matter, in this case compost, did not reduce Al-P, Fe-P, and Ca-P.

Abstract

The low uptake of N and P nutrients by maize plants can be caused by the low availability or levels of N and P nutrients in the soil used as the planting medium. The Alfisol soil used in the study had N-total levels of 0.15% (low) and P2O5 of 12.76 ppm (medium). The addition of phosphate solubilizing microbes, pelleted organic fertilizer, and inorganic fertilizer can increase the availability of N and P nutrients in the soil, so that plant uptake of N and P nutrients can also increase. This study aims to determine the effect of a combination of phosphate-solubilizing microbes (PSM), pelleted organic fertilizer, and inorganic fertilizer on the nutrient uptake of maize plants. This research was conducted at the Experimental Farm, Faculty of Agriculture, Hasanuddin University and plant samples were analyzed at Hasanuddin University's Soil Fertility Chemistry Laboratory, Department of Soil Science, Faculty of Agriculture. This study used a Randomised Group Design (RGD). The treatments consisted of a combination of M0 = without phosphate solubilizing microbes; M1 = addition of phosphate solubilizing microbes; B0 = without pelleted organic fertilizer; B1 = pelleted organic fertilizer dose of 5 tonnes/ha; B2 = pelleted organic fertilizer dose of 10 tonnes/ha; A0 = without inorganic fertilizer; A1 = inorganic fertilizer 50% of the recommended dose. The results showed that the M0B2A0 treatment produced plants with the highest level of N nutrient uptake, which was 633.33% higher than the M0B0A0 treatment. In comparison, the M1B2A1 treatment had plants with the highest level of P nutrient uptake, which was 933.33% higher than the M0B0A0 treatment.

Abstract

This study investigated and evaluated the implementation of governance practices concerning the control environment in government-operated water supply firms in South Sulawesi Province, Indonesia. The objective of this study was to ascertain the most effective methods for implementing governance within government-owned firms. It also examined the maturity level of the control environment. This study utilized the multiple case study method and focused on three observed organizations. The qualitative data was analyzed using implementation-level assessment and comparison analysis across the cases. Multiple discoveries were unveiled in this investigation. Initially, the implementation of a control environment in observed organizations was rudimentary. Furthermore, effective communication and coordination across pertinent departments enhanced control consciousness inside the organization. Furthermore, this study recognized the significance of employing a procedural selection process for audit firms. Nevertheless, multiple domains necessitate enhancement to augment the quality of governance, specifically recognizing the significance of risk management and compliance programs. Additional aspects that may arise in control environment practices, such as corporate culture and political difficulties, should be further investigated.

Abstract

Bawang merah salah satu komoditas sayuran penting yang banyak dibutuhkan masyarakat sebagai bumbu penyedap masakan. Kebutuhan dari tahun ke tahun mengalami peningkatan seiring dengan bertambahnya jumlah penduduk dan beragamnya produk olahan. Ketersediaannya yang langka menimbulkan keresahan di tengah masyarakat dan mempengaruhi inflasi secara nasional. Sebagai komoditas penting maka pemerintah mencanangkan produksi nasional bawang merah sebesar 1.410.847 ton. Untuk mencapai produksi tersebut dibutuhkan benih sebanyak 155.556 ton umbi bibit dan biji bibit (True shallot seed) sebanyak 28.590. Selama ini, biaya usahatani bawang merah khususnya dari bibit dapat mencapai 60% dari total biaya produksi dengan mutu bibit yang kurang memenuhi syarat agronomi. Karena bibit diperoleh dari umbi yang diseleksi dari hasil panen umbi untuk konsumsi. Semestinya produksi untuk bibit berbeda cara pe-nanganannya dengan produksi untuk konsumsi. Perbanyakan tanaman bawang merah dengan umbi memiliki kekurangan di antraanya biayanya mahal karena dibutuhkan bibit dalam jumlah besar (1,0-1,5 ton/ha), mudah rusak dan umur simpannya singkat (kurang 3 bulan) serta mengalami masa dormansi. Sedangkan keuntungan menggunakan biji adalah biaya produksinya rendah karena dibutuhkan 5-6 kg/ha, hemat biaya transportasi bibit,  umur simpan lebih lama (2 tahun), ukuran umbi  lebih besar, dan produksinya lebih tinggi. Penggunaan biji untuk bibit bawang merah merupakan alternatif dalam membudidayakan bawang merah lebih murah dengan produktivitas yang tinggi.   Kata Kunci, Bawang merah, biji untuk bibit, dan umbi untuk bibit.

Abstract

Bawang merah dikenal sebagai sayuran umbi merupakan salah satu komoditas penting, selain untuk bumbu dapur juga digunakan sebagai pengobatan herbal untuk meningkatkan imunitas tubuh. Peningkatan produktivitas bawang merah, selain meningkatkan hasil panen juga mengurangi biaya produksi per satuan hasil, sehingga margin keuntungan petani menjadi lebih besar. Kebutuhan bawang merah dalam negeri dari tahun ke tahun cenderung mengalami peningkatan seiring dengan beragamnya pemanfaatan bawang merah selain bumbu dapur juga bahan baku berbagai olahan. Petani membudidayakan bawang merah umumnya menggunakan bibit dari umbi. Dalam satu hektar dibutuhkan umbi bibit 1-1.2 ton/ha dengan ukuran umbi sedang (5-10 g), saat musim tanam tiba harga bibit bawang merah Rp40.0000-Rp50.000/kg. Harga bibit bawang merah melalui lapak daring sudah mencapai Rp75.000/kg, bagi petani yang modalnya terbatas pada sentra produksi menunda menanam dan beralih ke komoditas lain. Oleh karena itu, dibutuhkan alternatif sumber bibit yaitu mengggunakan biji botani atau true shallot seed (TSS). Kelebihan biji botani (TSS) sebagai bibit di antaranya hanya 4-6 kg/ha dibandingkan umbi yang mencapai 1-1,2 ton/ha, biaya bibit sekitar Rp18 juta/ha dibandingkan dengan umbi yang mencapai Rp50 juta-Rp60 juta/ha, lebih tahan simpan (2 tahun), ukuran umbi lebih besar dan seragam serta produktivitasnya lebih tinggi (>20 ton/ha). Budidaya bawang merah dari biji merupakan terobosan untuk meningkatkan produktivitas di atas rata-rata nasional (9,8 t/ha). Teknologi penanaman bawang merah menggunakan biji belum banyak dipahami di tingkat petani walau memilki banyak  keuntungan sehingga perlu dilakukan pelatihan dan demonstrasi plot. Kata kunci: Biji, umbi, bawang merah, produktivitas tinggi, ramah terhadap lingkungan.   ABSTRACT Shallots are known as bulb vegetables and are one of the essential commodities, not only used as kitchen spices but also as herbal medicine to boost the body's immunity. Increasing shallot productivity enhances yield and reduces production costs per unit of output, resulting in greater profit margins for farmers. The domestic demand for shallots tends to increase yearly, driven by their various uses, not only as spices but also as raw materials for various processed products. Farmers generally cultivate shallots using bulbs as planting material. One hectare of land requires 1-1.2 tons of medium-sized bulb seeds (5-10 g). During the planting season, the price of shallot seeds ranges from IDR.40,000 to IDR50,000/kg. The price of shallot seeds on online marketplaces has reached IDR75,000/kg, making farmers with limited capital in production centers postpone planting and switch to other commodities. Therefore, an alternative seed source is needed, which is botanical seeds or True Shallot Seed (TSS). The advantages of TSS include requiring only 4-6 kg/ha compared to bulbs which require 1-1.2 tons/ha, seed costs of around IDR18 million/ha compared to bulbs which reach IDR50 million-IDR60 million/ha, longer shelf life (up to 2 years), larger and more uniform bulb size, and higher productivity (>20 tons/ha). Shallot cultivation using TSS is a breakthrough to increase productivity above the national average (9.8 t/ha). However, farmers still do not widely understand the technology for planting shallots using seeds despite its many benefits, thus requiring training and demonstration plots. Keywords: Seeds, bulbs, shallots, high productivity and the environment friendly.
