Abstract

Keberhasilan pertumbuhan dan hasil panen tanaman salah satu faktornya ditentukan adalah viabilitas benih. Teknologi coating benih atau pelapisan benih merupakan solusi yang dapat diterapkan untuk meningkatkan viabilitas benih. Penelitian ini bertujuan untuk menganalisis aplikasi PGPR pada proses pelapisan benih dan mengidentifikasi jenis bahan pelapis yang efektif terhadap peningkatan viabilitas benih padi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan enam perlakuan dan tiga ulangan sehingga diperoleh 18 unit uji perkecambahan. Perlakuan terdiri dari kombinasi suspensi PGPR konsorsium rizobakteri (genus Bacillus sp, Bacillus amylolquifaciens) dan berbagai macam bahan pelapis (bubuk kelor, bubuk kopi, bubuk kunyit, tapioka, dan brown sugar). Hasil yang diperoleh menunjukkan bahwa perlakuan coating benih kombinasi PGPR dan bahan pelapis bubuk kelor memberikan kombinasi yang efektif terhadap rata-rata daya kecambah (59,92%), keserempakan tumbuh maksimum (47,67%KN/etmal), jumlah kecambah normal (65,00 biji), benih keras (2,33 biji), dan rata-rata benih mati (3,33 biji) dibandingkan perlakuan lainnya. Hasil penelitian ini dapat menjadi dasar bagi pengembangan teknologi pelapisan benih yang lebih efisien, hemat biaya dan ramah terhadap lingkungan sehingga pada akhirnya dapat berkontribusi pada peningkatan produktivitas pertanian sebagai upaya menjaga ketahanan pangan. The success of plant growth and yield is determined by seed viability. Seed coating technology is a solution that can be applied to increase seed viability. This study aims to analyze the application of PGPR in the seed coating process and identify the type of coating material that is most effective on rice seed viability. This study used a completely randomized design (CRD) with six treatments and three replications to obtain 18 germination test units. The treatments consisted of a combination of PGPR suspension of rhizobacterial consortium (genus Bacillus sp, Bacillus amylolquifaciens) and various coating materials (Moringa powder, coffee powder, turmeric powder, tapioca, and brown sugar). The results obtained showed that the seed coating treatment of a combination of PGPR and moringa powder coating material provided an effective combination of average germination (59.92%), maximum growth uniformity (47.67%KN/etm), number of normal sprouts (65.00 seeds), hard seeds (2.33 seeds), and average dead seeds (3.33 seeds) compared to other treatments. The results of this study can be the basis for the development of seed coating technology that is more efficient, cost-effective and environmentally friendly so that it can ultimately contribute to increasing agricultural productivity as an effort to maintain food security.

Abstract

Palm oil is one of the plantation commodities that play an important role in the Indonesian economy. Wild plants are still considered as harmful plants because in general people do not know their benefits. The purpose of this study was to identify and document wild plant species that grow under pine stands in Tinggimoncong District, Gowa Regency, South Sulawesi and analyze the potential benefits of wild plant species, especially related to their use in the fields of health, economic agriculture and other value-added products. The method used was the Exploration Method by exploring the research location of the habitat of wild plants under pine stands. The identification process is carried out by taking pictures of samples through the Picture This application available on the Google Playstore platform then matching using an invasive plant identification book. The results of the study found as many as 20 species of potential wildplants consisting of the families Asteraceae Poaceae Phyllanthaceae, Melastomataceae, Umbelliferae, Lamiaceae, Nephrolepidaceae, Polypodiaceae, Urticaceae, Plantaginaceae, Polygalaceae, Pteridaceae, Solanaceae, Rubiaceae, Verbenaceae, Caryophyllaceae. Families from Asteraceae, Poaceae, and Polypodiaceae produced more than 1 wild plant species compared to other families which only produced an average of 1 plant species. Overall, wild plants found under pine stands are useful as medicinal plants. Some species are useful as food for animal feed, ornamental plants, mosquito larvicides, foot sanitizers, sunscreen, natural pesticides, insecticides, and vegetable herbicides. This research contributes to the development of science, providing a positive impact on the empowerment of local communities, which not only provides scientific contributions but also sustainable socio-economic and environmental.

Abstract

Seed dormancy poses a serious challenge when aiming for precise and uniform sowing times in crop cultivation activities. Dormancy can reduce seed viability thus inhibiting germination and early plant growth. The purpose of this study was to test the effectiveness of gold snail extract enriched with PGPR (Plant Growth Promotion Rhizobacteria) bioactivator by optimizing the length of soaking in local rice seeds that experience dormancy. The research was conducted using a Completely Randomized Design (CRD) with 5 treatments of control soaking duration (P0), 12 hours soaking duration (P1), 24 hours (P2), 36 hours (P3) and 48 hours (P4) with 4 replications so that a total of 20 experimental units were obtained. Each experimental unit consisted of 25 local Kamba rice seeds by observing the percentage of germination, vigor index, growth speed, fresh weight, dry weight, root length and pH changes during the fermentation process. The results showed that various treatments of soaking time in gold snail extract enriched with PGPR bioactivator did not provide statistically significant differences in the germination of local rice seeds that experienced dormancy. However, there was an increasing trend in all observation parameters indicating that the viability and vigor of seeds soaked in gold snail extract for 36 hours (P3) were better than the control. pH and temperature observed before and after fermentation, showed conditions that remained optimal. The combination of gold snail extract added with PGPR as a bioactivator is an alternative solution that can accelerate the breaking of dormancy, increase seed viability and vigor as an effort to support more optimal and sustainable early growth of rice plants.

Abstract

Soy milk kefir offers a plant-based alternative to dairy probiotics. This study aimed to enhance both the chemical and functional characteristics of soy milk kefir by evaluating the effects of varying kefir grain starter doses and added Clitoria ternatea (telang) flower juice. A 3x4 factorial design was employed using three starter levels (40g, 50g, 60g per liter soy milk) and four telang juice concentrations (0ml, 10ml, 20ml, 30ml per liter). Key parameters analyzed post-fermentation included protein content (Kjeldahl), lactic acid (titration), pH, Water Holding Capacity (WHC, centrifugation), anthocyanin content (differential pH method), and Lactic Acid Bacteria (LAB) count (plate count). Results indicated significant (p<0.05) effects of both starter dose and telang juice concentration, and their interaction, on all measured characteristics. Specifically, the 40g starter + 30ml juice treatment yielded the highest protein (39.35%) and anthocyanin (18.42 mg/mL). The 50g starter + 20ml juice treatment showed the highest WHC (67.30%). The 60g starter + 30ml juice treatment produced the highest lactic acid (20.30%). Higher LAB counts were observed in several treatments including A0B0, A1B1, A2B2, and A2B3 compared to others. In conclusion, optimizing kefir grain dosage and adding telang flower juice significantly improves soy milk kefir's nutritional profile (protein) and functional attributes (anthocyanins, WHC, LAB), demonstrating its potential as an enhanced plant-based functional food.

Abstract

Tanah bekas likuifaksi umumnya memiliki kandungan bahan organik sangat rendah (<1%), struktur tanah rusak, porositas tidak stabil, serta aktivitas mikroba yang menurun sehingga memerlukan amandemen organik untuk memulihkan sifat fisik, kimia, dan biologinya. Pupuk kandang sapi menjadi pilihan solusi karena kaya C-organik dan unsur hara makro serta mudah terdekomposisi, sedangkan arang sekam berperan memperbaiki aerasi dan porositas tanah berpasir. Penelitian ini bertujuan mengkaji efektivitas pupuk kandang sapi dan arang sekam sebagai bahan amandemen tanah eks-likuifaksi di Desa Jono Oge serta dampaknya terhadap pertumbuhan dan hasil bawang merah lokal Palu. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan tujuh perlakuan, yaitu amandemen tanah + pupuk kandang (1:1), tanah + arang sekam (1:1), tanah + pupuk kandang + arang sekam (1:1:1), tanah + pupuk kandang (2:1), tanah + arang sekam (2:1), tanah + pupuk kandang + arang sekam (2:1:1), dan tanah tanpa amandemen sebagai kontrol dengan lima ulangan. Parameter yang diamati meliputi sifat fisik, kimia, dan biologi tanah serta pertumbuhan dan hasil tanaman. Hasil penelitian menunjukkan bahwa perlakuan kombinasi tanah bekas likuifaksi, pupuk kandang dan arang sekam rasio 1:1:1 memiliki tinggi tanaman (44,50 cm), bobot segar umbi (20,70 g), dan bobot kering umbi (8,97 g) bawang merah lokal palu tertinggi. Aplikasi bahan organik dengan proporsi seimbang terbukti efektif merehabilitasi tanah bekas likuifaksi dan meningkatkan produktivitas bawang merah lokal Palu sehingga berpotensi diterapkan sebagai strategi pertanian berkelanjutan pada lahan pasca bencana. ABSTRACT Post-liquefaction soil has very low organic matter content (<1%), damaged soil structure, unstable porosity, and decreased microbial activity, so it requires organic amendments to restore its physical, chemical, and biological properties. Cow manure is a solution of choice because it is rich in organic carbon and macronutrients and is readily decomposed, while rice husk charcoal improves aeration and porosity in sandy soil. This study aims to assess the effectiveness of cow manure and rice husk charcoal as amendments to post-liquefaction soil in Jono Oge Village and their impact on the growth and yield of local shallots in Palu. The study used a Completely Randomized Design (CRD) with seven treatments:  soil + manure (1:1), soil + rice husk charcoal (1:1), soil + manure + rice husk charcoal (1:1:1), soil + manure (2:1), soil + rice husk charcoal (2:1), soil + manure + rice husk charcoal (2:1:1), and soil without amendment as a control with five replications. The parameters observed were soil physical, chemical, and biological properties, plant growth and yield. The results showed that manure and rice husk charcoal in a ratio of 1:1:1 produced the highest of height (44.50 cm), fresh weight of bulbs (20.70 g), and dry weight of bulbs (8.97 g) of local Palu shallot plants. Organic materials application in balanced proportions has been proven effective in rehabilitating liquefied soil and increasing local Palu shallots productivity, suggesting its potential as a sustainable agricultural strategy in post-disaster areas.

Abstract

Synthetic insecticides are still used as the main solution in suppressing herbivorous insect attacks on maize at the farm level. The purpose of this research is to determine and find new ways farmers use insecticides wisely through a multi-aspect approach. The method used to determine the sample was purposive sampling with 50 corn farmers spread across five villages in the Tambulava sub-district. Primary data collection was obtained by observation through direct interviews with corn farmers using a prepared semi-structured questionnaire, and secondary data were obtained through a literature study and various sources related to research issues. Quantitative data were analyzed by simple tabulation (cross-tabulation analysis), while qualitative data were analyzed using an interpretation of existing phenomena. The results showed that four herbivorous insect species attacked corn plants in the Tanambulava District: Spodoptera frugiperda, Helicoverva armigera, Ostrinia furnacalis, and Locusta sp. Insecticide application time by local farmers is generally done in the morning by 90%, with application frequency varying 1-3 times a week. There are 13 active insecticide ingredients used by corn farmers in Tambulava District, Sigi Regency.

Abstract

Particularly in the waters of Tinangkung, Central Sulawesi, the management of seaweed through marine spatial planning and evidence-based site selection remains extremely limited. The objective of this study was to assess the suitability of the environment for Kappaphycus alvarezii cultivation based on spatial modeling using a Geographic Information System (GIS). Eight environmental parameters were tested, namely depth, temperature, salinity, brightness, current velocity, nutrients (nitrate and phosphate), pH, and dissolved oxygen (DO), which were integrated into GIS software using the weighted overlay method to produce a land suitability map. The results indicated that the area was divided into three suitability classes, namely highly suitable (S1) covering an area of ± 722.79 ha (31.8%), suitable (S2) covering an area of ± 1,616.72 ha (66.6%), and unsuitable (N) covering an area of ± 88.29 ha (3.6%). The central and southern zones of Tinangkung Bay are classified as highly suitable (S1) with stable water characteristics, high clarity, and optimal oxygen and salinity content. In contrast, coastal and estuarine areas are classified as less suitable (S2) due to the influence of land runoff, which alters salinity and pH. GIS-based modeling is effective in integrating environmental data to assist in a comprehensive mapping of marine aquaculture suitability. This study produced the first land suitability map for K. alvarezii aquaculture in Tinangkung waters, which can serve as a scientific basis for the formulation of marine spatial planning policies and sustainable seaweed aquaculture management in Central Sulawesi.
