Abstract

Perkembangan Kota Ambon sebagai ibu kota Provinsi Maluku dan kota Orde I dalam lingkup wilayah Provinsi Maluku memicu perkembangan struktur dan pola ruang meluas ke kawasan pesisir. Dampak pembangunan yang tidak terkendali turut mempengaruhi ekosistem mangrove berupa berkurangnya luasan lahan hutan mangrove di beberapa wilayah di Kota Ambon. Dengan mengamati komunitas mangrove di Teluk Ambon dilakukan pada wilayah perairan pantai Negeri Passo, Waiheru, Nania, Negeri Lama, dan Poka, yang mewakili wilayah Teluk Ambon Dalam dan Negeri Tawiri, yang mewakili wilayah Teluk Ambon Luar. Dengan metode eksploratif dan teknik pengolahan data citra, pengamatan dan analisa dampak. Hasil penelitian menunjukan pengurangan luasan hutan mangrove dipengaruhi oleh wilayah pemanfaatan untuk permukiman penduduk, jembatan dan Pelabuhan, Pasar Mardika, Hotel/Penginapan, Restoran dan Café, tempat rekreasi, fasilitas kesehatan, penambangan bahan galian C, pertanian, docking, perikanan tangkap, perikanan budidaya, tempat pembuangan sampah, Dampaknya adalah komunitas mangrove tidak banyak ditemukan pada Teluk Ambon Bagian Luar karena pengaruh arus dan gelombang yang relatif besar dan perairan Teluk Ambon Bagian Luar ekosistem mangrove hanya ditemukan pada wilayah pantai Negeri Tawiri. Komposisi spesies mangrove pada wilayah Teluk Ambon secara keseluruhan, diperoleh 19 Spesies mangrove sejati tergolong dalam 10 famili dan 13 genus. Jumlah spesies mangrove pada perairan Teluk Ambon lebih rendah dibandingkan jumlah spesies mangrove di Indonesia. Indikator dampak juga ditunjukkan dengan nilai kualitas air sungai yang tidak sesuai dengan baku mutu (bau, warna, DO, BOD, COD dan keberadaan E. coli), semakin meningkatnya sampah padat yang dihasilkan, serta tingginya sedimentasi pada beberapa wilayah mangrove di perairan Teluk Ambon

Abstract

The research aims to determine the species richness, diversity and distribution of mangrove populations in forest areas, which is one of the parameters of forest health in the Passo Village’s mangrove forest. It was conducted from July to August 2023 on Ambon Island using the Forest Health Monitoring Field Methods Guide. The research covered 2 hectares of mangrove forest with 3 clusters of 12 observation plots. It was found that seven species of mangroves were found in the area, namely Sonneratia alba,  Rhizophorastylosa, Avicennia marina, Aegiceras corniculatum, Bruguiera gymnorrhyza and Bruguiera parviflora. Cluster 1 had 260 trees. Cluster 2 had 321 trees, and Cluster 3 had 193 trees. The highest value of mangrove species richness was at the sapling level of 1,003. Meanwhile, the species diversity was classified as low at only 0.701 at the seedling level. The highest density of the Sonneratia alba species was 4,290, the species dominance of the Sonneratia alba was 22,240, and the highest importance index occupied by the Sonneratia alba was 160.95. Considering the low level of mangrove forest biodiversity on Ambon Island, rehabilitation and reforestation efforts are needed to maintain the quality and health of the ecosystem, especially in facing the impact of climate change on small islands.

Abstract

The Ralstonia solanacearum species complex is a highly destructive plant pathogen with a remarkably broad range of hosts, and ongoing discoveries continue to expand its host list. In May 2023, a new type of bacterial wilt affecting ginger (Z. officinale) crops in Semarang Regency, Central Java was reported. Early symptoms included sudden withering of leaves in adult plants followed by complete wilting and darkening of the vasculature, ultimately leading to plant death. This research specifically investigates the spread of Ralstonia solanacearum Species Complex within ginger cultivation in Semarang Regency. Twenty bacterial isolates were collected from soil and diseased Z. officinale plants at twenty different locations. Physiological and biochemical analyses confirmed that the causative agent for Z. officinale bacterial wilt was Ralstonia solanacearum belonging to biovar 3 and 4. The study also revealed that the distribution of this pathogen remains focused in the Banyubiru and Sumowono sub-districts. These findings will enhance our understanding of how Ralstonia solanacearum Species Complex spreads among ginger crops and its impact on them.

Abstract

Hortikultura sebagai subsektor pertanian menjadi salah satu penyumbang peningkatan devisa negara devisa negara, salah satunya adalah komoditas bawang merah. Jumlah produksi bawang merah mencapai 2 juta ton pada tahun 2021 lebih tinggi jika dibandingkan dengan komoditas hortikultura lainnya seperti cabai merah besar yang hanya mencapai 1,2 juta ton dan cabai rawit sebesar 1,3 juta ton. Hal tersebut berdampak positif terhadap ekspor sehingga volume ekspor bawang merah mengalami peningkatan. Sebagai komoditas musiman, Produksi bawang merah seringkali mengalami fluktuasi sehingga berdampak pada harga bawang merah yang juga berfluktuasi baik di pasar dalam negeri maupun bawang merah yang diperdagangkan di luar negeri. Tujuan penelitian ini adalah untuk menganalisis daya saing bawang merah Indonesia di pasar negara ASEAN, dan faktor-faktor yang mempengaruhi volume ekspor bawang merah Indonesia ke negara ASEAN. Penelitiannini menggunakan analisissRCA (Revealed Comparative Advantage), EPD (Export Product Dynamic), potensi X-Model ekspor, dan regresi data panel dengan data observasi sebanyak 15 tahun. Hasil penelitian menunjukkan Indonesia mempunyai keunggulan komparatif berdasarkan analisis RCA tahun 2007-2021 di pasar Thailand dan Vietnam, sedangkan Indonesia hanya memiliki keunggulan kompetitif di pasar Thailand serta memiliki potensi pengembangan pasar optimis di pasar Thailand. Faktor-faktor yang dapat meningkatkan volume ekspor bawang merah Indonesia adalah GDP riil negara ASEAN sedangkan yang dapat menurunkan volume ekspor bawang merah Indonesia ke pasar ASEAN adalah nilai tukar, populasi, harga ekspor dan jumlah produksi bawang merah negara ASEAN.

Abstract

Penelitian ini bertujuan untuk penggambaran struktur rantai pasok jeruk siam, menganalisis struktur biaya logistik, dan menyusun strategi alternatif untuk tier rantai pasok jeruk siam, dengan tujuan untuk memperbaiki distribusi pendapatan yang lebih merata dan meningkatkan pendapatan petani. Total responden pada penelitian ini sebanyak 21 orang. Metode yang digunakan untuk melakukan analisis biaya logistik adalah metode Activity-Based Costing (ABC). Hasil dari penelitian ini adalah sistem rantai pasok komoditas jeruk siam terdiri dari empat tier, dengan tier utamanya adalah petani, pengepul desa, pedagang besar (collector), dan pedagang kecil (retail seller). Hasil perhitungan biaya logistik menunjukkan bahwa total biaya logistik sebesar Rp8.113.21/kg dengan 53,31% merupakan biaya yang berasal dari aktivitas material handling dan 46,69% lainnya adalah biaya dari aktivitas procurement, transportation, inventory, dan information. Berdasarkan perhitungan biaya logistik, ada beberapa rekomendasi yang dapat dilakukan, seperti menambah aktivitas pascapanen di tingkat petani dan menerapkan aktivitas logistik yang lebih efisien dan responsif di tingkat petani. Strategi Vendor Managed Inventory (VMI) sebaiknya digunakan dalam semua pola rantai pasok.

Abstract

Potatoes are among the vegetables highly susceptible to climate change, and its consequences can significantly affect technical efficiency.However, the production of potato relatively fluctuated due to some factors influencing it. The study aims to analyze the factors affecting potato production, measure the level of technical efficiency in potato farming, and identify the socio-economic factors that influence technical inefficiency in potato farming, both in the rainy and dry seasons. The study was conducted in Merangin Regency, Jambi Province. A purposive sampling method was used to select the research area and collect data from 102 potato farmers. The data were analyzed using the Stochastic Frontier Cobb-Douglas production function model with a maximum likelihood estimation (MLE) approach. The research results show that land and seed variables significantly influence potato production, both in the rainy and dry seasons. Meanwhile, fertilizer P and labor only significantly influence the dry season. The average level of technical efficiency in the dry season (0.89) is higher than in the rainy season (0.73). The results of the average difference test (t-test) show that in the dry season, the level of technical efficiency has a higher value than in the rainy season, with a significance of 1%. The significant socio-economic variables influencing technical efficiency are membership in farmer groups.
