Abstract

Maize has attracted the attention of local governments due to its high yield potential and economic prospects, but the strategic value of this commodity has not been specific to particular locations. Therefore, this study aimed to assess degraded land suitability and determine the regional comparative advantages for maize development in the Gorontalo sustainable agriculture areas. The suitability class was assessed using Automatic Land Evaluation System software, while comparative advantages were determined using input-output and regional analysis. The input-output analysis was based on maize farming data from interviews with 80 farmers. This study also employed location quotient, specialization index, and localization index analyses based on maize, rice, and soybean production data for 2014, 2016, and 2018. The results showed that land degradation caused by soil erosion was dominated by moderate, heavy, and very heavy categories. Most of the actual land suitability for maize was classified as marginal suitable (S3) but became very suitable (S1) and moderately suitable (S2) after the limiting factors were improved. Furthermore, maize was profitable for the land suitability classes of S1, S2, and S3, and the commodity was most concentrated in Mootilango District. Based on the results, land management recommendations followed a pattern of recommendation I > II > III > not recommended.

AbstractThe lack of water availability and the short period of maize growth has the potential to be the main obstacles to achieving optimal production. Therefore, this research aimed to determine the water availability and long growth period (LGP) of maize plants in Boalemo Regency, which was included in the agrokilmat zone E2. Rainfall and temperature data from Saritani, Tangkobu, and Bubaa climate stations in Boalemo Regency were used over ten years, from 2012 to 2022. The soil profile moisture content data used pF 2.5 and pF 4.2 while the tool used Cropwat8.0. Furthermore, the determination of available water and LGP was conducted using a water balance table with the Thornwaite method. The results showed that the highest and lowest water availabilities were 556 mm and 118 mm at the Saritani and Tangkobu climate stations, with a maximum LGP of maize at 242 days and 181 days, respectively. Based on climate stations, the availability of water and the amount of LGP follow the pattern of Saritani climate station > Bubaa climate station > Tangkobu climate station.

Abstract

The signifcant efect of land quality on maize production has not been fully considered in the existing land suitability criteria.Terefore, this study aims to determine land suitability criteria for hybrid maize in Boalemo Regency based on the optimum yieldand land quality. It was carried out in Boalemo Regency, Indonesia, where the land unit of 67 units was surveyed to obtain landcharacteristics data. A partial least square of structural equation model (PLS-SEM) with SmartPLS 8.0 was used to select a robustland quality controlling hybrid maize yield, while the boundary line method was used to determine optimum yield and differentiating of land suitability criteria. Te result showed that land qualities that defne the optimum yield of hybrid maize wereroot conditions, nutrient availability, nutrient retentions, land preparation, and erosion hazard. Te soil characteristics wereefective depth, coarse material, organic C, total N, K exchangeable, slopes, soil erosion, rock outcrops, and surface rocks.Furthermore, the highest optimum yield of 8.54 ton/ha was achieved by the total N and slopes for a very suitable class (S1), whilethe lowest of 5.58 ton/ha was obtained by exchangeable K for class S1. Tis showed that the combination of PLS-SEM andboundary line analysis was a better approach to developing new land suitability criteria for hybrid maize.

Abstract

Porang is becoming recognized as a strategic commodity due to its high demand and substantial economic value. However, the lack of a standardized set of site-specific land suitability criteria for porang presents challenges in conducting land suitability assessments and planning for its use. Therefore, this study addressed the knowledge gap by evaluating land suitability classes and the implications of land management for porang cultivation, using different parametric methods. A comprehensive survey of 32 land units was conducted, followed by soil analysis in the laboratory. The square root (SRM) and the Rabia and Terribile (RTM) parametric methods were employed for the land suitability assessment. Subsequently, the land management priorities were determined based on the results of the land suitability class analysis derived from both methods. The results showed that land suitability for porang plants with SRM and RTM was dominated by the very suitable class (S1), however, the distribution of S1 was wider with RTM. The remaining classes with SRM consisted of moderately suitable (S2), marginally suitable (S3), currently not suitable (N1), and permanently not suitable (N2), while the remaining classes with RTM only consisted of S1, S2, and S3 classes without class N. The priority of land management for porang plants for both parametric methods is dominated by priority I, however, in SRM there are priorities II, III, and NP (not priority), while in RTM, there are only II and III. Based on land suitability class and land management priority, RTM was still better than SRM.

Nasionalisme Pangan Profesor Go Ban Hong

Selasa, 09 Sep 2014 16:30 WIB,   1,004x

Oleh: J Anto. Menjadi Soekarnois tak selalu identik dengan menjadi anggota atau kader dari partai politik atau ormas yang mengusung ideologi Soekarnoisme. Seorang yang disebut Soekarnois juga tak mesti pernah memiliki pertalian politik saat presiden pertama itu berkuasa. Bahkan tak mesti pula berasal dari trah biologis Soekarno itu sendiri.

Prof. Dr. Go Ban Hong jelas bukan seorang Soekarnois dalam arti ideologis seperti itu. Ia hanya seorang Guru Besar. Seorang ilmuwan yang mendedikasikan sebagian besar hidup dan ilmunya untuk pertanian, khususnya bidang penelitian ilmu tanah untuk pengem­bangan pertanian pangan.

Sebuah pilihan karier yang tergolong "sunyi" (dari publikasi media massa), "kering" (dari materi), namun mampu menerjemahkan idealismenya sebagai ilmuwan.

Jalan hidup Profesor Go, begitu ia dipanggil, setidaknya memang dipengaruhi oleh Soekarno. Lebih tepat lagi, ajaran Soekarno tentang kemandirian pangan. Perhatian pada isu ketahanan pangan inilah yang menautkan keduanya.

Tentang pikiran Soekarno terhadap pentingnya ketahanan pangan bagi suatu negara, menurut Andreas Maryoto (Maryoto: 2009) bisa diilacak dari tiga babak hidup Soekarno ketika menghadapi krisis pangan, mulai dari Soekarno muda hingga diturunkan sebagai presiden pada tahun 1967.

Sejumlah tulisan Soekarno muda yang terangkum dalam bukunya yang berjudul Di Bawah Bendera Revolusi menyiratkan kegelisahan Soekarno terhadap rakyat yang kesulitan pangan pada tahun 1932-1933. Salah satu topik yang sempat diperdebatkan adalah, "Mana jang lebih baik, beras atau djagung, dan mengapa?"

Bagi Prof Go sendiri, pengabdiannya terhadap pembangunan pertanian pangan bermula dari peristiwa 27 April 1952. Saat itu di Kampung Baranang Siang, Bogor, sebuah sejarah tengah ditoreh di lapangan pendidikan Indonesia. Presiden RI Dr. Ir. Soekarno meletakkan batu pertama pemba­ngunan kampus Fakultas Pertanian Univer­sitas Indonesia, yang kelak berubah menjadi Institut Pertanian Bogor (IPB).

Ada pidato Soekarno di situ. Pidato yang telah mengubah jalan hidup seorang Go Ban Hong, salah satu mahasiswa yang ikut menyaksikan acara itu. Ban Hong muda waktu itu merasa larut dalam alam pikiran Soekarno yang bicara tentang pentingnya penyediaan pangan bagi rakyat. Menurut Soekarno kecukupan pangan menentukan "mati hidupnya bangsa kita."

Dan masalah pangan menurut Soekarno hanya dapat diselesaikan oleh orang-orang yang sung­guh memahami persoalan pangan, berlatar belakang pendidikan pertanian dan pangan. Soekarno menge­tuk kesadaran pemuda Indonesia agar menempuh pendidikan pertanian di Bogor karena Indononesia saat itu sangat kekurangan kader di lapangan perta­nian dan peternakan.

Pidato Soekarno itu rupanya mampu mengge­rak­kan hati Ban Hong yang saat itu tengah me­nung­gu untuk diwisuda pada tahun berikutnya 1953. Ban Hong mengaku terkesan dengan seruan Bung Karno yang mene­gaskan pentingnya perta­nian tanah kering atau peladangan. Seruan itulah yang meman­tapkan hati­nya mendalami ilmu tanah dan menekuni profesi pene­liti ilmu tanah.

Keputusan Ban Hong mengabdi pada ilmu tanah selain didorong keinginan kuat mewu­judkan visi Bung Karno tentang kecukupan pangan juga didorong oleh munculnya kesadaran filo­sofis dirinya bahwa hidup mati manusia berada di atas tanah. Karena itu, pendalaman, pengemba­ngan, dan penerapan ilmu tanah sangat penting bagi kelangsungan hidup ma­nusia.
