Abstract

The cassava production center in Bogor City is produced by Ciluar Village. Based on the potential of Ciluar Village, which has a lot of cassava agricultural land, cassava peel waste has the potential to be used as organic fertilizer. The aims of this paper are (1) to find out the minimum time to produce compost with the basic ingredients of cassava peels and goat manure with pH parameters according to Indonesian National Standard (SNI) standard; (2) to find out the best composition between cassava skin and goat manure to produce compost. There were three types of treatment based on weight composition comparison between cassava skin and goat manure. The results of the compost quality test were analyzed (statistical test) using analysis of variance (ANOVA) and LSD test (Lessest Significant Difference) to determine the effect of treatment on the observed variables with the help of IBM SPSS 26 software. The conclusions of this study include: (1) the minimum time to produce compost made from cassava peels and goat manure with pH parameters according to SNI is 42 days; (2) the best composition between cassava skin and goat manure to produce compost is a ratio of 7:3.

Abstract

Bahan organik dan mikroorganisme diperlukan untuk memperbaiki sifat fisik tanah pasca galian batuan agar dapat digunakan untuk budidaya tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi bahan organik dan mikroorganisme tanah terhadap perbaikan fisik tanah pasca galian batuan dan pertumbuhan cabai rawit. Penelitian dilaksanakan di Cibiru Bandung, Jawa Barat dengan titik ordinat  -6.92049471880716, 107.716127309820, dari bulan Juni sampai Oktober 2020, menggunakan Rancangan Acak Kelompok (RAK) Faktorial  dua faktor dan diulang tiga kali. Faktor pertama yaitu bahan organik: b0 : kontrol (tanpa pemberian bahan organik), b1: kompos Paitan 15 t ha-1, b2: kompos eceng gondok 15 t ha-1, b3: abu cangkang sawit 15 t ha-1. Faktor kedua : mikroba: mo: kontrol (tanpa pemberian mikroba), m1 : Inokulum campuran Fungi Mikoriza Asburkular (FMA) 10 g polibag-1, m2 :Inokulum campuran  BPF (Bakteri Pelarut Fosfat) 10 ml polibag-1, m3 : campuran FMA dan BPF. Hasil penelitian menunjukkan eceng gondok 15 t ha-1 yang diberikan bersamaan dengan FMA atau BPF menaikan kelembaban tanah. Aplikasi bahan organik dan mikroba menurunkan agregat stabil tahan air. Eceng gondok dan BPF masing-masing menurunkan suhu tanah. Aplikasi bahan organik dan mikroorganisme belum berpengaruh dalam peningkatan pertumbuhan tanaman cabai rawit, namun berpengaruh terhadap fisik tanah  tanah pasca galian batuan.ABSTRACTOrganic matters and microorganisms are needed to improve the physical properties of the post-mine sand pits soil so that it can be used for plant cultivation. The purpose of this study was to know the influence of organic matters and soil microorganism application on post-mine sand pits soil improvement and chili pepper growth. This study was conducted in Cibiru Bandung (-6.92049471880716, 107.716127309820), from June to October 2020, using Block Randomized Factorial Design two factors and repeated three times. The first factor was organic matters: b0 : control, b1: compost Titonia 15 t ha-1, b2: compost Hyacinth 15 t ha-1, b3: palm shell ash 15 tha-1. The second factor: microbes: m0: control, m1: mix inoculum AMF  10 g polybag-1, m2 : mix inoculum PSB 10 ml polybag-1 , m3 : mixture of AMF and PSB. The results showed that hyacinth 15 t ha-1 given with FMA or PSB increased soil moisture. The application of organic matters and microbes decreased water stable aggregates. Hyacinth and PSB lower the temperature of the soil. The application of organic matters and microorganisms has not had an effect in increasing the growth of chili pepper plants but influences the physical properties of the post-mine sand pit  soil.

Abstract

Coral transplantation is the activity of cultivating/breeding coral colonies using the fragmentation method. Several techniques have been used in transplant activities, but knowledge of the right transplantation technique is needed so the activities can run well. This study aims to determine the effect of different types of substrate and attachment media used on the growth rate and survival of Acropora tenuis corals transplanted into three attachment media at Karang Malang beach at a depth of two meters. The research was carried out for four months, March-June 2023 through field research using a randomized block design method with two factors, namely the type of substrate used (cement, coral, clay, glass bottles, cans) and different attachment media (control, cement, epoxy). The results of the analysis showed that the use of cement as a fixing medium was more effective and affected coral growth and the growth rate of Acropora tenuis than epoxy and without adhering media. The highest growth rate was found in cement attachment media, which was 0.62 cm/month, and the lowest in the method without attachment media, namely 0.45 cm/month. While the epoxy sticking method is 0.51 cm/month. The survival rate for cement attachment media was 96%, epoxy adhesion media was 88% and treatment without attachment media/control was 76%.
