ABSTRACT
The UNHAS Campus Intellectual Product Development Program (PPUPIK) aims to produce Unhas Synthetic Corn Seeds (SINHAS-1) to support corn development on dry and marginal lands, particularly in the face of drought and low nitrogen availability, which have been major obstacles in national corn production. Seed production will be carried out through seed production stages at the Exfarm of the Faculty of Agriculture, Hasanuddin University, and partner fields in Bajeng District, Gowa Regency, from May to October 2025. The process follows Good Seed Production Practices (GSPP), including variety isolation, plant maintenance, roguing, harvesting, drying to a moisture content of <12%, cleaning using a seed cleaner, certification, and packaging before distribution to farmers and relevant partners. The SINHAS-1 variety demonstrates high seed quality with genetic purity ≥98% and germination rate >90%, in accordance with SNI 01-6233-2000. Productivity reaches 2.5 t/ha during the dry season and remains stable under abiotic stress conditions. The seed price is IDR 15,000/kg, which is more affordable than hybrid seeds (>IDR 100,000/kg). The implementation of the program also increases students\u27 capacity in seed entrepreneurship, strengthens the function of Exfarm as a campus seed business unit, and expands farmers\u27 access to adaptive superior seeds for marginal land.
Keywords: SINHAS-1, marginal land, open-pollinated seeds, stress tolerance, seed production
Study of Wheat (Triticum aestivum L.) Seed Deterioration Pattern Using a Systems Approach
Full text linkWheat seeds, one of the orthodox seed types, naturally experience a decline in quality during long-term storage. This deterioration is a complex process that involves various factors throughout the seed\u27s lifecycle. However, seed deterioration studies are based on static approaches. Therefore, moving from static to dynamic indicators, which describe changes in the state of seed biological systems over time, would be exciting. The study aimed to estimate the vigor and storability of wheat seeds based on a systems approach. The research was carried out using a systems approach, while the stages of the research were as follows: literature study and data collection from several scientific journals, preparation of flowcharts, models, simulations, and validation. The results showed that the estimation of wheat seed deterioration could be predicted through a systems approach. The estimation of wheat seed deterioration is a system that involves many variables that are interrelated and occur simultaneously. The following equations can estimate the wheat seed deterioration model: ROS(t) = ROS(t - dt) + (-H2O2) x dt; H2O2 = ROS x Changes index of H2O2; MDA = 4.62271 + (18.4012 - 4.62271) x exp (-22.2767 x H2O2 1.70613); FFA = 123.336 x exp (-10.1865 x H2O2); germination = 2.30234 + (109.524 - 2.30234) / (1 + exp (11.4657 x ln (\u27MDA\u27 / 9.39342))). During storage, antioxidant enzymes that degrade reactive oxygen species (ROS) become inactive. The accumulation of ROS leads to membrane damage, resulting in decreased vigor, which is characterized by reduced germination rates
Pengaruh Pemberian Trichokompos dan Unsur Hara Zn Terhadap Fisiologis dan Produksi Biji Tanaman Kakao (Theobroma cacao L.): The Effect of Trichokompos and Zn Fertilizer on the Physiology and Seed Production of Cocoa Plants (Theobroma cacao L.)
Full text linkPenelitian ini bertujuan untuk mempelajari dan menganalisis pengaruh kombinasi trichokompos dan unsur hara Zn terhadap produktivitas tanaman kakao. Penelitian ini dilaksanakan di Desa Pasang, Kecamatan Maiwa, Kabupaten Enrekang, Provinsi Sulawesi Selatan, dilaksanakan pada April hingga Oktober 2024. Penelitian dilaksanakan dalam bentuk percobaan di lapangan menggunakan Rancangan Petak Terpisah (RPT), petak utama adalah trichokompos yang terdiri atas 3 taraf, yaitu: tanpa trichokompos (kontrol), 7,5 ton/ha, dan 15 ton/ha, sedangkan anak petak adalah pupuk Zn yang terdiri atas 4 taraf, yaitu: kontrol (tanpa pupuk Zn), Pupuk Zn 0,25 g/L, Pupuk Zn 0,50 g/L, dan Pupuk Zn 0,75 g/L. Berdasarkan kedua faktor tersebut terdapat 12 kombinasi perlakuan dengan 3 ulangan menggunakan 2 tanaman sehingga terdapat 72 tanaman yang diamati. Hasil penelitian menunjukkan bahwa aplikasi pupuk Zn secara nyata meningkatkan komponen fisiologis tanaman kakao, menurunkan persentase jumlah bunga dan pentil buah yang gugur serta memperbaiki kualitas buah kakao. Pupuk Zn 0,50 g/L memberikan hasil terbaik terhadap kandungan klorofil a (317,84 µmol m-2), klorofil b (138,59 µmol m-2), klorofil total (457,72 µmol m-2), dan persentase bunga gugur (72,76%). Aplikasi pupuk Zn 0,75 g/L memberikan jumlah pentil buah gugur terbaik (74,34%). Walaupun tidak terdapat interaksi yang nyata dari kedua perlakuan, pemberian pupuk Trichokompos dan Pupuk Zn cenderung meningkatkan jumlah biji per buah dan bobot 100 biji kering tanaman kakao

Comparison of Mangrove and Coastal Ecosystem Management Strategies between Padang City (Indonesia) and Port Dickson (Malaysia) to Support Coastal Resilience
Full text linkMangrove and coastal ecosystems play a critical role in enhancing coastal resilience; however, their effectiveness strongly depends on governance arrangements and management strategies. This study applies a qualitative comparative case study approach integrating a Systematic Literature Review (SLR) and field observations to compare mangrove and coastal ecosystem management strategies in Padang City (Indonesia) and Port Dickson (Malaysia). A structured comparative framework was used to assess biophysical conditions, governance structures, monitoring capacity, community participation, and contributions to ecological, institutional, and social resilience. The results indicate that Padang City possesses larger mangrove extent and higher species diversity, supporting stronger ecological and social resilience, but is constrained by fragmented governance and weak enforcement. Port Dickson exhibits smaller and fragmented mangrove areas with clearer institutional authority and periodic monitoring, yet limited social–ecological integration. The findings highlight that effective coastal resilience requires integrating strong regulatory frameworks, community engagement, and consistent long-term monitoring
Responsibility of Business Operators in the Sale and Purchase of Ulcer Medication for Abortion on Facebook Marketplace in Merauke
Full text linkThis study aims to analyze the responsibility of business actors in the sale and purchase of ulcer medication for abortion through the Facebook marketplace and to analyze the legal remedies available to consumers who suffer losses in online transactions through the Facebook marketplace. The type of legal research used in this study is empirical legal research. In addressing this research issue, the primary legal materials used consisted of interviews with business actors and consumers involved in the sale and purchase of stomach ulcer medication. Secondary legal materials consisted of information or facts obtained indirectly through social media, journals, studies, books, and scientific works related to consumer protection law and health law. The issues studied were analyzed qualitatively and the data was then presented descriptively. The results of the study show that (1) Business actors are not fully responsible for the losses suffered by consumers because they only provide a refund of half the price of the medicine purchased, and there are even business actors who end the conversation by blocking consumers on messenger chat media. This is not in accordance with consumer rights as stipulated in Article 4 of the UUPK, Article 7 of the UUPK regarding the obligations of business actors, and Article 19 of the UUPK regarding the responsibilities of business actors. (2) Legal actions that can be taken by consumers who have suffered losses from online transactions on Facebook Marketplace include suing business operators through the general court or through the Consumer Dispute Settlement Agency (BPSK), but to date, no consumers have filed lawsuits in the general court or BPSK. Moreover, there is no BPSK in Merauke, so consumers who feel aggrieved must file a lawsuit with the BPSK in Jayapura
Illocutionary Speech Acts in the Lyrics of “Mathasibnish” Based on Searle’s Theory
Full text linkSong lyrics as a form of poetic text not only serve an aesthetic function but also contain a communicative dimension that reflects the speaker’s attitudes, intentions, and emotional states within interpersonal relationships. In the context of modern popular Arabic music, themes of betrayal and disappointment are frequently represented through language rich in pragmatic meaning. This study aims to examine the realization of illocutionary speech acts in the lyrics of “Mathasibnish” written by Amir Teima and popularized by Sherine Abdel Wahab. The research employs a qualitative descriptive approach, drawing on speech act theory proposed by J. L. Austin and further developed by John Searle, which classifies illocutionary acts into representative, directive, commissive, expressive, and declarative categories. The data consist of utterances in the song lyrics, collected through documentation techniques and analyzed through processes of identification, classification, and interpretation of their pragmatic functions. The findings reveal that four types of illocutionary speech acts are present in the lyrics, namely representatives, directives, commissives, and expressives, while declaratives are not identified. The dominance of expressive acts emphasizes that the song discourse is oriented toward the expression of emotion, particularly feelings of disappointment and inner pain resulting from betrayal. Meanwhile, representative, directive, and commissive acts function to reinforce the speaker’s position and decisions within the relationship
Sosialisasi Stunting dengan Tema Gizi Optimal, Tumbuh Maksimal di Desa Ujung Labuang
Full text linkMasalah stunting masih menjadi fokus utama pembangunan kesehatan di Indonesia karena berpengaruh terhadap kualitas sumber daya manusia di masa depan. Meskipun kebijakan nasional telah diarahkan untuk menurunkan angka stunting, beberapa wilayah seperti Desa Ujung Labuang, Kabupaten Pinrang, masih menghadapi tantangan dalam implementasi di lapangan. Berdasarkan data BKKBN (2025), tercatat 13 anak balita mengalami stunting di Desa Ujung Labuang. Kondisi tersebut mencerminkan masih perlunya upaya berkelanjutan dalam peningkatan pengetahuan dan perubahan perilaku masyarakat terkait gizi anak. Sehubungan dengan hal tersebut, kegiatan sosialisasi ini diselenggarakan sebagai upaya strategis untuk meningkatkan pemahaman dan kesadaran masyarakat mengenai pencegahan dan penanganan stunting. Metode yang digunakan meliputi sosialisasi langsung melalui pemaparan materi dan diskusi interaktif dengan sasaran masyarakat yang memiliki anak balita, terutama yang terindikasi stunting. Evaluasi keberhasilan dilakukan melalui observasi keterlibatan peserta dan pengumpulan umpan balik pasca kegiatan. Hasil evaluasi terhadap 33 peserta sosialisasi pencegahan dan penanganan stunting, secara umum terdapat peningkatan pengetahuan pada mayoritas peserta. Hasil akumulasi dari empat aspek penilaian menunjukkan bahwa sebanyak 27 peserta (81,8%) mengalami peningkatan pengetahuan, sedangkan 6 peserta (18,2%) memiliki pengetahuan yang relatif tetap. Antusiasme peserta terlihat dari keaktifan dalam bertanya, berdiskusi, serta memberikan tanggapan positif terhadap materi yang disampaikan. Dengan demikian, kegiatan ini diharapkan dapat menjadi langkah awal dalam membangun kesadaran kolektif masyarakat desa untuk berperan aktif dalam pencegahan stunting secara berkelanjutan
